Title: Toy gun capable of piercing two air bottles

Description:
BACKGROUND OF THE INVENTION 
     Field of the Invention 
     The present invention relates to a toy gun structure and in particular to a toy gun capable of piercing two air bottles. 
     Description of Prior Art 
     The current toy gun which uses an air bottle as a power source to shoot bullets utilizes the air cylinder which is installed in the gun body to receive the air steel bottle. One end of the air cylinder is provided with a thimble corresponding to the bottle mouth of the air steel bottle; the other end of the air cylinder is screwed to the screw base pressing against the air steel bottle. The screw base can be rotated to push and position the air steel bottle in the gun body. Meanwhile, the bottle mouth of the air steel bottle is pierced by the thimble to release the compressed air in the air steel bottle to provide the power to shoot bullets. 
     However, the above-mentioned air steel bottle pushed by rotating the screw base to pierce the bottle mouth suffers the following disadvantages. The screw base needs rotating more turns to push the air steel bottle into the air cylinder, which is time- and labor-consuming for the user and actually requires improvement, especially in a survival game in which every second counts. 
     In view of this, the inventor pays special attention to research with the application of related theory and tries to improve and overcome the above disadvantages regarding the prior art, which becomes the improvement target of the inventor. 
     SUMMARY OF THE INVENTION 
     The present invention provides a toy gun capable of piercing two air bottles. The toy gun uses the push rod that can be pressed to drive two air bottles to be individually pierced by the first piercing member and the second piercing member, which further have the effect of quickly piercing two air bottles. 
     In an embodiment, the present invention provides a toy gun capable of piercing two air bottles installed therein. The toy gun comprises a gun body, a first piercing member, a screw base, and a moveable rod assembly. The gun body has an air cylinder. One end of the air cylinder is provided with a connecting tube; the other end of the air cylinder is provided with a screwed tube. The two air bottles are arranged bottom to bottom and received in the air cylinder. The first piercing member is disposed in the connecting tube. The screw base has an end screwed to the screwed tube and the other end with a bottom end. The screw base is provided with a throughhole penetrating through the bottom end and communicating with the interior of the air cylinder. The moveable rod assembly has a push rod that can move to penetrate through the throughhole and to protrude from the bottom end and a return spring flexibly held between the screw base and the push rod. The second piercing member is disposed at an end of the push rod away from the bottom end. When the push rod is pressed, the push rod can drive the second piercing member to pierce one of the two air bottles and then move the other of the two air bottles towards the first piercing member to be pierced by the first piercing member. 
     Compared with the prior art which needs more turns for the screw seat to push the air bottle into the air cylinder, the push rod used in the present invention is just pressed to push the air bottle into the air cylinder such that the air bottles are quickly pierced by the first piercing member and by the second piercing member. Therefore, the toy gun of the present invention has the effects of quickly piercing the air bottles and a two-stage piercing of air bottles.

     DETAILED DESCRIPTION OF THE INVENTION 
     The detailed description and technical details of the present invention will be explained below with reference to accompanying drawings. However, the accompanying figures are for reference and explanation only, but not to limit the scope of the present invention. 
     Please refer to  FIGS. 1-4 . The present invention provides a toy gun capable of piercing two air bottles. The toy gun  10  comprises a gun body  1 , a first piercing member  2 , a screw base  3 , and a moveable rod assembly  4 . 
     The toy gun  10  of the present invention is used to install two air bottles  100 . Each air bottle  100  has a bottle mouth  101  at one end thereof and a bottle bottom  102  at the other end thereof. The compressed air generated after the air bottle  100  is pierced is used to provide the actuating power for the toy gun  10 . 
     The gun body  1  has an air cylinder  11 . One end of the air cylinder  11  is provided with a connecting tube  111  and the other end of the air cylinder  11  is provided with a screwed tube  112 . The connecting tube  111  communicates with the gun barrel (not shown) of the gun body  1  and is used to guide the compressed air generated from the air bottle  100  to flow into the gun barrel to shoot the bullets (not shown). An internal thread  113  is disposed at an inner edge of the screwed tube  112 . 
     In addition, the two air bottles  100  are arranged bottom to bottom and received in the air cylinder  11 . The bottle mouth  101  of one of the two air bottles  100  is disposed corresponding to the connecting tube  111 ; the bottle bottom  102  of the other of the two air bottles  100  is disposed corresponding to the screwed tube  112 . The bottle bottoms  102  of the two air bottles  100  press against each other. The first piercing member  2  is disposed in the connecting tube  111 . 
     The screw base  3  has an end with a top end  31  and the other end with a bottom end  32 . The screw base  3  is provided with a throughhole  33  penetrating through the bottom end  32  and communicating with the interior of the air cylinder  11 . 
     The detailed description is given below. The outer edge of the screw base  3  is provided with an external thread  34  and a second ring groove  35 . The external thread  34  and the internal thread  113  are engaged to each other such that the top end  31  of the screw base  3  is screwed to the screwed tube  112 . 
     Moreover, the bottom end  32  is provided with a recess portion  321  and a bottom surface  322  formed in the recess portion  321 ; the throughhole  33  is formed through the bottom surface  322 . The inner edge of the throughhole  33  extends to form a first projection  331 , a second projection  332 , and a first ring groove  333  disposed between the first projection  331  and the second projection  332 . The top end  31  is provided with a V-shaped recess  311  to fit the shape of the bottle bottom  102  of the air bottle  100 , but not limited to this. 
     The moveable rod assembly  4  has a push rod  41  and a return spring  42 . The push rod  41  can move to penetrate through the throughhole  33  and to protrude from the bottom end  32 . The return spring  42  is flexibly held between the screw base  3  and the push rod  41 . A second piercing member  414  is disposed at an end of the push rod  41  away from the bottom end  32 . 
     Further description is given below. The push rod  41  has a rod body  411  and a press block  412  attached firmly to the rod body  411 . The rod body  411  is disposed through the throughhole  33 ; the press block  412  protrudes from the bottom end  32  and is moveably embedded in the recess portion  321 . 
     In addition, the extruded part  413  extends from an end of the rod body  411  away from the press block  412 . The extruded part  413  can be stopped by the first projection  331  to prevent the rod body  411  from separating from the throughhole  33 . Also, the second piercing member  414  is a piercing pin  415  protruding from the top of the extruded part  413 . 
     In addition, the return spring  42  has a first spring  421  and a second spring  422 . The first spring  421  is clamped between the bottom surface  322  and the press block  412 . The press block  412  can be returned to protrude from the top end  32  by the spring return force of the first spring  421  and drives the extruded part  413  to be received in the throughhole  33 . The second spring  422  is clamped between the extruded part  413  and the second projection  332 . 
     Further description is given below. Without external force applied, the spring return force of the first spring  421  is larger than that of the second spring  422 , which drives the extruded part  413  to be received in the throughhole  33  and the second spring  422  not to return to its original length to be in a compressed state. However, when the press block  412  is pressed to compress the first spring  421  to move the rod body  411  towards the interior of the air cylinder  11 , the second spring  422  flexibly returns to a stretched state and drives the extruded part  413  to press against the air bottle  100  and prevent the air bottle  100  from swaying. 
     When the push rod  41  is pressed by the user, the push rod  41  can move the second piercing member  414  to pierce one of the two air bottles  100  and then move the other of the two air bottles towards the first piercing member  2  to be pierced by the first piercing member  2 . 
     The toy gun  10  of the present invention further comprises a first seal ring  5  that is clamped between the rod body  411  and the screw base  3 ; the first seal ring  5  is received and embedded in the first ring groove  333 . The first seal ring  5  is used to provide an airtight seal between the rod body  411  and the screw base  3 . 
     The toy gun  10  of the present invention further comprises a second seal ring  6  that is clamped between the screwed tube  112  and the screw base  3 ; the second seal ring  6  is received and embedded in the second ring groove  35 . The second seal ring  6  is used to provide an airtight seal between the screwed tube  112  and the screw base  3 . 
       FIGS. 3 and 4  are schematic views of the toy gun  10  of the present invention in operational states. After two air bottles  100  are installed in the air cylinder  11 , the user presses the press block  412  to compress the first spring  421  and move the rod body  411  towards the interior of the air cylinder  11 . Meanwhile, the extruded part  413  is firstly pressed against the bottle mouth  101  of one of the two air bottles  100  such that the second piercing member  414  pierces the bottle mouth  101  of the air bottle  100 . The compressed air generated after the air bottle  100  is pierced flows into the gun barrel through the connecting tube  111  to shoot the bullet. 
     After that, when the user continues to press the press block  412 , the extruded part  413  moves the other air bottle  100  towards the first piercing member  2  until the bottle mouth  101  of the air bottle  100  is pierced by the first piercing member  2 , which achieves the effect of piercing the air bottles by a two-stage procedure. 
     The traditional screw base needs to rotate more turns to move the air bottle into the air cylinder whereas the push rod  41  in the present invention is just pressed and then the air bottle  100  can be pushed into the air cylinder  11  such that the air bottles  100  can be quickly pierced by the first piercing member  2  and by the second piercing member  414 . That is, the toy gun  10  has the effects of quickly piercing the air bottles  100  and a two-stage piercing of air bottles. 
     Furthermore, the spring return force of the first spring  421  can return the extruded part  413  to be received in the throughhole  33  such that the extruded part  413  can remain in the throughhole  33  and cannot touch the air bottle  100  when the push rod  41  is not pressed by the user. Such a design can prevent the air bottle  100  from being carelessly touched to be pierced by the first piercing member  2  or by the second piercing member  414 . 
     In summary, the toy gun capable of piercing two air bottles of the present invention indeed achieves the expected objectives and overcomes the disadvantages of the prior art. Also, the present invention is novel, useful, and non-obvious to be patentable. Please examine the application carefully and grant it as a formal patent for protecting the rights of the inventor.
