Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The invention relates to coaxial cable strippers and more particularly to a coaxial cable stripper of the type that is equipped with functionality which can adjust depth of cuts, and cut off of both individual insulating layers of a coaxial cable. 
         [0003]    2. Description of Related Art 
         [0004]    In order to cut the double layers of insulating material off of a coaxial cable, the traditional method is as follows: 
         [0005]    Directly utilize sharp blade to cutoff both the insulating layers of a coaxial cable. Individually cut the double layers off of insulating material off of a coaxial cable via a sharp blade of a clamp. 
         [0006]    The disadvantages of these two types of implementation are that the coaxial cable risks being cut apart, stripped a part, or deformed due to improper operations by users. 
         [0007]    Due to the fact that the market demand is very high in terms of cutting the double layer of insulating material off of coaxial cables, inventors have been developing tools that will improve the aforementioned disadvantages. There are already two prior art that perform these aforementioned implementations. The theory of cutoff in both of these patents is via two cutting components of a coaxial cable stripper by first tightly clamp down a coaxial cable at the coaxial cable stripper, followed by rotating the coaxial cable or the coaxial cable stripper, then utilize the two cutting components on the coaxial cable stripper to individually cut the double layers of insulating material off of the coaxial cable. Upon further inspection, although the two aforementioned patents can achieve the cutoff functionality of the double layers of insulating material of a coaxial cable, the depth of cut is a fixated value due to the two cutting components utilized by the coaxial cable stripper. Therefore, the tool is only useful for a given unchangeable coaxial cable specification. If the goal is to cutoff a different coaxial of different specification, the cutting component must be exchanged or replaced. This special requirement will bring inconveniences to a user especially during portable applications. 
         [0008]    Bearing above conventional drawbacks in mind, a novel coaxial cable stripper having the ability of varying depth of cut is finally developed. 
       SUMMARY OF THE INVENTION 
       [0009]    It is therefore one object of the invention to provide a coaxial cable stripper which is applicable for cutting coaxial cable; furthermore, the cutting component on the coaxial cable stripper is capable of adjusting the depth of cuts. The coaxial cable stripper comprises a main body, a first spring, a shaft body, and a rotatable, displaceable part. Wherein the main body has a first hollow structure, one receptacle is disposed at one end of the main body, the receptacle is interconnected with the first hollow structure, a first guide hole is disposed on one side of the receptacle, a second guide hole is disposed on the other side of the receptacle, a first hole and an eighth hole are disposed adjacent to the receptacle; the first spring is disposed within the first hollow structure; the shaft body passes through the receptacle and is placed within the first hollow structure, the first spring is disposed between the shaft body and the first hollow structure; moreover, the first spring pushes the shaft body and the first hollow structure, a through hole for rod is disposed at the shaft body, a rod first passes through the first guide hole then passes through the through hole for rod and finally enters into the second guide hole, a third hole is disposed at the shaft body, a first gap and a second gap are disposed within the third hole, a fifth hole is disposed at one side of the shaft body, a first blade guide groove and a first blade seat are disposed within the shaft body, a first blade and a first polygonal hole are disposed at the first blade seat, the first blade seat is disposed at the first blade guide groove, moreover, the first blade seat can move on the first blade guide groove, the first blade guide groove leads the first blade to displace on the first blade seat, the first blade may protrude outside of the first gap, a second spring is disposed within the shaft body, the second spring is disposed between the first blade seat and the shaft body, furthermore, the second spring pushes simultaneously against the first blade seat and the shaft body, a second blade is disposed at the shaft body and the second blade may protrude outside of the second gap; an extension is disposed at the rotatable, displaceable part, a first polygonal cylinder is disposed at the extension, the first polygonal cylinder can rotate inside the first polygonal hole, the extension passes first through the eighth hole then through the fifth hole and finally into the first polygonal hole. 
         [0010]    The shaft body also comprises a second blade seat which is equipped with the second blade and a second polygonal hole, the second blade seat is installed at the second blade guide groove, moreover, the second blade seat is movable at the second blade guide groove, the second blade guide groove guides the second blade to displace on the second blade seat, a third spring is installed between the second blade seat and the shaft body, moreover, the third spring simultaneously pushes against the second blade seat and the shaft body; the extension comprises: a second polygonal cylinder; rotation made by rotatable, displaceable part leads the second polygonal cylinder to rotate inside the second polygonal hole, the second polygonal cylinder provides adjustments to various edges of the second polygonal cylinder which push against the second polygonal hole, subsequently leading the second blade seat to displace along the second blade guide groove, hence, to adjust the height of the second blade at the second blade seat that protrudes outside of the second gap. 
         [0011]    Theory behind adjusting a cutting component to produce variable depth of cut: Rotate the rotatable, displaceable part causes the first polygonal cylinder to rotate inside the first polygonal hole, subsequently, various edges of the first polygonal cylinder will push against the first polygonal hole, leading the first blade seat to displace along the first blade guide groove, hence, resulting in making adjustment to the height of the first blade at the first blade seat that protrudes outside of the first gap; and/or rotate the rotatable, displaceable part causes the second polygonal cylinder to rotate inside the second polygonal hole, subsequently, various edges of the second polygonal cylinder will push against the second polygonal hole, this action leads the second blade seat to displace along the second blade guide groove, resulting in making adjustment to the height of the second blade at the second blade seat that protrudes outside of the second gap. 
         [0012]    Following is the theory of variable depth of cut utilizing the first blade and the second blade: 
         [0013]    The height of the first blade that protrudes outside of the first gap A 1  for example: H 2  or H 3  is different from the height of the second blade that protrudes outside of the second gap A 2  for example: Hence, two different depths of cuts can be simultaneously against the coaxial cable. 
         [0014]    Following is the theory of cutting a coaxial cable: 
         [0015]    Rotate the rotatable and displaceable part causes the first polygonal cylinder to rotate inside the first polygonal hole, subsequently, various edges of the first polygonal cylinder will push against the first polygonal hole, leading the first blade seat to displace along the first blade guide groove, hence, resulting in making adjustment to the height of the first blade at the first blade seat that protrudes outside of the first gap. 
         [0016]    When a thrust F is applied to the shaft body of the coaxial cable stripper, the thrust F will compress the first spring. The guidance of the first guide hole and the second guide hole along the rod causes the shaft body to displace towards the direction of the hollow structure; hence, the movement leads the third hole to displace towards the hollow structure. A coaxial cable can be placed within the third hole of the coaxial cable stripper once the third hole overlaps with the first hole. 
         [0017]    Stress at the shaft body is relieved once thrust F is removed. When that happens, the first spring will be automatically trending back to its original position. In addition, the shaft body will be guided by the first guide hole and the second guide hole at the rod and be pushed away from the hollow structure the blockage from the rod will not allow the shaft body and the hollow structure to completely separate. At this moment, the coaxial cable being placed in the third hole will be clamped tightly inside the third hole while the first blade and the second blade will make their cuts into the coaxial cable. 
         [0018]    The coaxial cable is held securely because of the difference in depth made by the cuts coming from the first blade and the second cut, and following by rotating the coaxial cable stripper or secure the coaxial cable stripper and follow by rotating the coaxial cable, the first insulating layer and the second insulating layer will therefore be cut off. 
         [0019]    The above and other objects, features and advantages of the invention will become apparent from the following detailed description taken with the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0063]    Referring to  FIGS. 1 to 43 , a coaxial cable stripper  100  in accordance with the invention comprises the following components as discussed in detail below. 
         [0064]    The coaxial cable stripper  100  is applicable for cutting coaxial cables  200 . The coaxial cable stripper  100  comprises a main body  10 , a first spring  21 , a shaft body  30 , and a rotatable, displaceable part  40 . 
         [0065]    The main body  10  has a first hollow structure  11 , one receptacle  12  is disposed at one end of the main body  10 , the receptacle  12  is interconnected with the first hollow structure  11 , a first guide hole  13  is disposed on one side of the receptacle  12 , a second guide hole  14  is disposed on the other side of the receptacle  12 , and a first hole  61  and an eighth hole  68  are disposed adjacent to the receptacle  12 . 
         [0066]    The first spring  21  is disposed within the first hollow structure  11 ; the shaft body  30  passes through the receptacle  12  and is placed within the first hollow structure  11 , the first spring  21  is disposed between the shaft body  30  and the first hollow structure  11 ; moreover, the first spring  21  pushes the shaft body  30  and the first hollow structure  11 , a through hole for rod  33  is disposed at the shaft body  30 , a rod  50  first passes through the first guide hole  13  then passes through the through hole for rod  33  and finally enters into the second guide hole  14 , a third hole  63  is disposed at the shaft body  30 , a first gap A 1  and a second gap A 2  are disposed within the third hole  63 , a fifth hole  65  is disposed at one side of the shaft body  30 , a first blade guide groove  35  and a first blade seat  31  are disposed within the shaft body  30 , a first blade  311  and a first polygonal hole  81  are disposed at the first blade seat  31 , the first blade seat  31  is disposed at the first blade guide groove  35 , moreover, the first blade seat  31  can move on the first blade guide groove  35 , the first blade guide groove  35  leads the first blade  311  to displace on the first blade seat  31 , the first blade  311  may protrude outside of the first gap A 1 , a second spring  22  is disposed within the shaft body  30 , the second spring  22  is disposed between the first blade seat  31  and the shaft body  30 , furthermore, the second spring  22  pushes simultaneously against the first blade seat  31  and the shaft body  30 , a second blade  321  is disposed at the shaft body  30  and the second blade  321  may protrude outside of the second gap A 2 . 
         [0067]    An extension  41  is disposed at the rotatable, displaceable part  40 , a first polygonal cylinder  411  is disposed at the extension  41 , the first polygonal cylinder  411  can rotate inside the first polygonal hole  81 , the extension  41  passes first through the eighth hole  68  then through the fifth hole  65  and finally into the first polygonal hole  81 . 
         [0068]    Thus, rotation made by rotatable, displaceable part  40  leads the first polygonal cylinder  411  to rotate inside the second polygonal hole  81 , the first polygonal cylinder  411  provides adjustments to various edges of the first polygonal cylinder  411  which push against the first polygonal hole  411 , subsequently leading the first blade seat  31  to displace along the first blade guide groove  35 , hence, to adjust the height of the first blade  311  at the second blade seat  31  that protrudes outside of the second gap A 1 . 
         [0069]    When a thrust F is applied to the shaft body  30  of the coaxial cable stripper  100 , the thrust F will compress the first spring  21 . The guidance of the first guide hole  13  and the second guide hole  14  along the rod  50  causes the shaft body  30  to displace towards the direction of the hollow structure  11  rotatable, displaceable part  40  will also move at the eighth hole  68 ; hence, the movement leads the third hole  63  to displace towards the hollow structure  11 . A coaxial cable  200  can be placed within the third hole  63  of the coaxial cable stripper  100  once the third hole  63  overlaps with the first hole  61 . 
         [0070]    Stress at the shaft body  30  is relieved once thrust F is removed. When that happens, the first spring  21  will be automatically trending back to its original position. In addition, the shaft body  30  will be guided by the first guide hole  13  and the second guide hole  14  at the rod  50  and be pushed away from the hollow structure  11 ; moreover, the blockage from the rod  50  will not allow the shaft body  30  and the hollow structure  11  to completely separate. At this moment, the coaxial cable  200  being placed in the third hole  63  will be clamped tightly inside the third hole  63  while the first blade  311  and the second blade  321  will make their cuts into the coaxial cable  200 . 
         [0071]    After the coaxial cable  200  is securely held and follow by rotating the coaxial cable stripper  100 , the first blade  311  and the second blade  321  will cut the first insulating layer  210  and/or the second insulating layer  220  off of the coaxial cable  200  or secure the coaxial cable stripper  100  and follow by rotating the coaxial cable  200 , the first blade  311  and the second blade  321  will cut the first insulating layer  210  and/or second insulating layer  220  off of the coaxial cable  200 . 
         [0072]    Also in this example, the first hole  61  and the eighth hole  68  are interconnected; hence, the rotatable, displaceable part  40  is allowed to rotate and/or move while inside the first hole  61  and the eighth hole  68 . 
         [0073]    Also in this example, the other side of the receptacle  12  has the second hole  62 , the second hole  62  is interconnected with the first hole  61 ; hence, the coaxial cable  200  is allowed to be placed within the second hole  62  and the first hole  61 . 
         [0074]    Also in this example, the shaft body  30  comprises: the second blade seat  32  at where the second blade  321  and a fourth hole  64  are installed, wherein the extension  41  passes through the eighth hole  68 , then passes through the fifth hole  65 , then passes first polygonal hole  81 , then finally into the fourth hole  64 . 
         [0075]    Also in this example, the shaft body  30  comprises a seventh hole  67 , wherein the extension passes through the eight hole  68 , then passes through the fifth hole  65 , then passes through the first polygonal hole  81 , then passes through the fourth hole  64 , then finally into the seventh hole  67 . 
         [0076]    Also in this example, first polygonal hole  81  comprises a third flat surface  81 A. The first polygonal cylinder  411  comprises a first flat surface  411 A. When the first polygonal cylinder  411 A is rotated, the first flat surface  411 A pushes against the third flat surface  81 A. Through the rotation of the rotatable, displaceable part  40 , the first polygonal cylinder  411  is driven to rotate inside the first polygonal hole  81 . The first flat surface  411 A pushes the third flat surface  81 A, which leads the first blade seat  31  to displace at the first blade guide groove  35 ; hence, resulting in making adjustment to the height of the first blade  311  at the first blade seat  31  that protrudes outside of the first gap A 1 . 
         [0077]    Also in this example, the first polygonal hole  81  comprises a first positioning slot  81 B. The first polygonal cylinder  411  comprises a first protrusion  411 B. When the first polygonal cylinder  411  rotates, the first protrusion  411 B can be positioned inside the first positioning slot  81 B and pushes against the first positioning slot  81 B. Through the rotation of the rotatable, displaceable part  40 , the first polygonal cylinder  411  is driven to rotate inside the first polygonal hole  81 . The first protrusion  411 B can be positioned inside the first positioning slot  81 B and pushes against the first positioning slot  81 B, leading the first blade seat  31  at the first blade guide groove  35  to displace; hence, allowing the adjustment of the height of the first blade  311  at the first blade seat  31  that protrudes outside of the first gap A 1 . 
         [0078]    Also in this example, extension  41  comprises a groove  42  which is lodged at the eighth hole  68 ; hence, the rotatable, displaceable part  40  can move and rotate at the eighth hole  68 , the rotatable, displaceable part  40  can rotate at the eighth hole  68 , or the rotatable, displaceable part  40  can move at the eighth hole  68 . 
         [0079]    Also in this example, the shaft body  30  comprises a second blade seat  32  at which the second blade  321  and the second polygonal hole are disposed, furthermore, the second blade seat  32  is disposed at the second blade guide groove  36  and is also movable along the second blade guide groove  36  which guides the displacement of second blade  321  on the second blade seat  32 ; a third spring  23  is installed between the second blade seat  32  and the shaft body  30  while simultaneously pushes the second blade seat  32  and the shaft body  30 ; the extension comprises: a second polygonal cylinder  421 . The rotation of the rotatable, displaceable part  40  drives the second polygonal cylinder  421  to rotate inside the second polygonal hole  82  while adjusting various edges of the second polygonal cylinder  421  to push the second polygonal hole  82 ; moreover, the rotation of the rotatable, displaceable part  40  also drives the second blade seat  32  to displace on the second blade guide groove  36  in order to adjust the height of the second blade  321  of the second blade seat  32  that protrudes outside of the second gap A 2 . 
         [0080]    Also in this example, extension  41  passes through the eighth hole  68 , then passes through the fifth hole  65 , then passes through the first polygonal hole  81 , then finally into the second polygonal hole  82 . 
         [0081]    Also in the example, the shaft body  30  comprises a seventh hole  67 . The extension passes through the eighth hole  68 , then passes through the fifth hole  65 , then passes first polygonal hole  81 , then passes through the second polygonal hole  82 , and finally into the seventh hole  67 . 
         [0082]    Also in this example, the second polygonal hole  82  comprises a fourth flat surface  82 A. The second polygonal cylinder  421  comprises a second flat surface  421 A. When the second polygonal cylinder  421  rotates, the second flat surface  421 A can push against the fourth flat surface  82 A. The rotation of the rotatable, displaceable part  40  drives the second polygonal cylinder  421  to rotate inside the second polygonal hole  82 , while the second flat surface  421 A push against the fourth flat surface  82 A, the action drives the second blade seat  32  to displace along the second blade guide groove  36 ; hence, resulting in making adjustment to the height of the second blade  321  of the second blade seat  32  that protrudes outside of the second gap A 2 . 
         [0083]    Also in this example, the second polygonal hole  82  comprises a second positioning slot  82 B. The second polygonal cylinder  421  comprises a second protrusion  421 B. When the second polygonal cylinder  421  rotates, the rotation causes the second protrusion  421 B to position inside the second positioning slot  82 B while pushing against the second positioning slot  82 B; therefore, the rotation of the rotatable, displaceable part  40  drives the second polygonal cylinder  421  to rotate inside the second polygonal hole, moreover, the second protrusion can be positioned at inside the second positioning slot  82 B and pushes against the second positioning slot  82 B, and the rotation of the rotatable, displaceable part  40  also drives the second blade seat  32  to displace along the second blade guide groove  36 ; hence, resulting in making adjustment to the height of the second blade  321  of the second blade seat  32  that protrudes outside of the second gap A 2 . 
         [0084]    Also in this example, a wrench is secured to the main body  10 . The wrench  200  can be used to lock bolts. 
         [0085]    Following is a description of first operations of the coaxial cable stripper  100 : 
         [0086]    The rotation of the rotatable, displaceable part  40  causes the extension to rotate, which drives the first polygonal cylinder  411  to rotate inside the first polygonal hole. 
         [0087]    The rotation of the first polygonal cylinder  411  pushes the first polygonal hole  81  upward or downward, which causes the first blade seat  31  to displace along the first blade guide groove  35 , which further pushes the first blade  311  of the first blade seat  31  upward or allows the first blade  311  of the first blade seat  31  to move downward; hence, resulting in making adjustment to the height of the first blade  311  which protrudes outside of the first gap A 1  the second spring  22  of the shaft body  30  will simultaneously push against the first blade seat  31  and the shaft body  30 . 
         [0088]    Because the height of first blade  311  that protrudes outside the first gap A 1  e.g., H 2  or H 3  is different from the height of the second blade  321  that protrudes outside the second gap A 2  e.g., H 1 ; therefore, two separate cuts having different depth can be made against the coaxial cable  200 . 
         [0089]    Since the shaft body  30  and the first spring  21  pushing against each other, when a thrust F is applied against the shaft body  30  of the coaxial cable stripper  100 , the thrust F will compress the first spring  21 , the shaft body  30  displaces towards the hollow structure  11  via the guidance of the first guide hole  13  and the second guide hole  14  the rotatable, displaceable part  40  will also move at the eighth hole  68 ; hence, these movements leads the third hole  63  to displace toward the hollow structure  11 , coaxial cable  200  can be placed within the third hold  63  of the coaxial cable stripper  100  once the third hole  63  and the first hole  61  overlap and lined up with each other. 
         [0090]    Stress at the shaft body  30  is relieved once thrust F is removed, the first spring  21  will be automatically trending back to its original position, in addition, the shaft body  30  will be guided by the first guide hole  13  and the second guide hole  14  at the rod  50  and be pushed away from the hollow structure  11  the blockage from the rod  50  will not allow the shaft body  30  and the hollow structure  11  to completely separate At this moment, the coaxial cable  200  being placed in the third hole  63  will be clamped tightly inside the third hole  63  while the first blade  311  and the second blade  321  will make their cuts into the coaxial cable  200 . 
         [0091]    After the coaxial cable  200  is securely held and follow by rotating the coaxial cable stripper  100 , the first blade  311  and the second blade  321  will cut the first insulating layer  210  and/or the second insulating layer  220  off of the coaxial cable  200  or secure the coaxial cable stripper  100  and follow by rotating the coaxial cable  200 , the first blade  311  and the second blade  321  will cut the first insulating layer  210  and/or second insulating layer  220  off of the coaxial cable  200 . 
         [0092]    Following is a description of second operations of the coaxial cable stripper  100 : 
         [0093]    The rotation of extension  41  of the rotatable, displaceable part  40  causes the second polygonal cylinder to rotate inside the second polygonal hole  82 . 
         [0094]    The rotation of the second polygonal cylinder  421  pushes the second polygonal hole  82  upward or downward, which causes the second blade seat  32  to displace along the second blade guide groove  36 , which further pushes the second blade  321  of the second blade seat  32  upward or allows the second blade  321  of the second blade seat  32  to move downward; hence, resulting in making adjustment to the height of the second blade  321  which protrudes outside of the second gap A 2  the third spring  23  of the shaft body  30  will simultaneously push against the second blade seat  32  and the shaft body  30 . 
         [0095]    Because the height of second blade  321  that protrudes outside the second gap A 2  e.g., H 5  or H 6  is different from the height of the first blade  311  that protrudes outside the first gap A 1  e.g., H 4 ; therefore, two separate cuts having different depth can be made against the coaxial cable  200 . 
         [0096]    Since the shaft body  30  and the first spring  21  pushing against each other, when a thrust F is applied against the shaft body  30  of the coaxial cable stripper  100 , the thrust F will compress the first spring  21 , the shaft body  30  displaces towards the hollow structure  11  via the guidance of the first guide hole  13  and the second guide hole  14  the rotatable, displaceable part  40  will also move at the eighth hole  68 ; hence, these movements leads the third hole  63  to displace toward the hollow structure  11 , coaxial cable  200  can be placed within the third hold  63  of the coaxial cable stripper  100  once the third hole  63  and the first hole  61  overlap and lined up with each other. 
         [0097]    Stress at the shaft body  30  is relieved once thrust F is removed, the first spring  21  will be automatically trending back to its original position, in addition, the shaft body  30  will be guided by the first guide hole  13  and the second guide hole  14  at the rod  50  and be pushed away from the hollow structure  11  the blockage from the rod  50  will not allow the shaft body  30  and the hollow structure  11  to completely separate. At this moment, the coaxial cable  200  being placed in the third hole  63  will be clamped tightly inside the third hole  63  while the first blade  311  and the second blade  321  will make their cuts into the coaxial cable  200 . 
         [0098]    After the coaxial cable  200  is securely held and follow by rotating the coaxial cable stripper  100 , the first blade  311  and the second blade  321  will cut the first insulating layer  210  and/or the second insulating layer  220  off of the coaxial cable  200  or secure the coaxial cable stripper  100  and follow by rotating the coaxial cable  200 , the first blade  311  and the second blade  321  will cut the first insulating layer  210  and/or second insulating layer  220  off of the coaxial cable  200 . 
         [0099]    Following is a description of third operations of the coaxial cable stripper  100 : 
         [0100]    The rotation of the rotatable, displaceable part  40  drives the extension  41  to rotate. The rotation of the extension  41  will result in the rotation of the first polygonal cylinder  411  to rotate inside the first polygonal hole  81 ; the rotation of the first polygonal cylinder  411  to rotate inside the first polygonal hole  81 . 
         [0101]    The rotation of the first polygonal cylinder  411  and the rotation of the second polygonal cylinder  421  will result in the rotation of the first polygonal cylinder  411  pushes the first polygonal hole  81  upward or downward, which causes the first blade seat  31  to displace along the first blade guide groove  35 , which further pushes the first blade  311  of the first blade seat  31  upward or allows the first blade  311  of the first blade seat  31  to move downward; hence, resulting in making adjustment to the height of the first blade  311  which protrudes outside of the first gap A 1  the second spring  22  of the shaft body  30  will simultaneously push against the first blade seat  31  and the shaft body  30 . 
         [0102]    The rotation of the second polygonal cylinder  421  pushes the second polygonal hole  82  upward or downward, which causes the second blade seat  32  to displace along the second blade guide groove  36 , which further pushes the second blade  321  of the second blade seat  32  upward or allows the second blade  321  of the second blade seat  32  to move downward; hence, resulting in making adjustment to the height of the second blade  321  which protrudes outside of the second gap A 2  the third spring  23  of the shaft body  30  will simultaneously push against the second blade seat  32  and the shaft body  30 . 
         [0103]    The reasons why two different cuts have different depths can be made to coaxial cable are below. The height of the first blade  311  that protrudes outside of the first gap A 1  for example: H 2  or H 3  is different from the height of the second blade  321  that protrudes outside of the second gap A 2  for example: H 1 ; or the height of the second blade  321  that protrudes outsides of the second gap A 2  for example: H 5  or H 6  is different from the height of the first blade  311  that protrudes outsides of the first gap A 1  for example: H 4 . 
         [0104]    Since the shaft body  30  and the first spring  21  pushing against each other, when a thrust F is applied against the shaft body  30  of the coaxial cable stripper  100 , the thrust F will compress the first spring  21 , the shaft body  30  displaces towards the hollow structure  11  via the guidance of the first guide hole  13  and the second guide hole  14  the rotatable, displaceable part  40  will also move at the eighth hole  68 ; hence, these movements leads the third hole  63  to displace toward the hollow structure  11 , coaxial cable  200  can be placed within the third hold  63  of the coaxial cable stripper  100  once the third hole  63  and the first hole  61  overlap and lined up with each other. 
         [0105]    Stress at the shaft body  30  is relieved once thrust F is removed, the first spring  21  will be automatically trending back to its original position, in addition, the shaft body  30  will be guided by the first guide hole  13  and the second guide hole  14  at the rod  50  and be pushed away from the hollow structure  11  the blockage from the rod  50  will not allow the shaft body  30  and the hollow structure  11  to completely separate. At this moment, the coaxial cable  200  being placed in the third hole  63  will be clamped tightly inside the third hole  63  while the first blade  311  and the second blade  321  will make their cuts into the coaxial cable  200 . 
         [0106]    After the coaxial cable  200  is securely held and follow by rotating the coaxial cable stripper  100 , the first blade  311  and the second blade  321  will cut the first insulating layer  210  and/or the second insulating layer  220  off of the coaxial cable  200  or secure the coaxial cable stripper  100  and follow by rotating the coaxial cable  200 , the first blade  311  and the second blade  321  will cut the first insulating layer  210  and/or second insulating layer  220  off of the coaxial cable  200 .
