Description:
BACKGROUND OF THE INVENTION  
       [0001] 1. Field of the Invention  
       [0002] The present invention relates to a grip structure for fixing an angled socket, and more particularly to a grip structure for fixing an angled socket, so that the user may use the angled socket to operate the workpiece easily and conveniently.  
       [0003] 2. Description of the Related Art  
       [0004] A conventional angled socket structure  1  in accordance with the prior art shown in FIGS. 1 and 2 is disclosed in the Taiwanese Patent Publication No. 450158, and comprises a drive body  11 , a driven body  12 , an L-shaped linking bar  13  mounted between the drive body  11  and the driven body  12 , and multiple L-shaped drive bars  14  mounted between the drive body  11  and the driven body  12 . The drive body  11  has a center formed with a linking hole  111  and multiple mounting holes  112  arranged around a periphery of the linking hole  111 . The drive body  11  has one end formed with an insertion hole  113  communicating with the linking hole  111  for insertion of pins  15 . The driven body  12  has a center formed with a linking hole  121  and multiple mounting holes  122  arranged around a periphery of the linking hole  121 . The driven body  12  has one end formed with an insertion hole  123  communicating with the linking hole  121  for insertion of pins  15 . The L-shaped linking bar  13  has two ends each formed with a locking groove  131 . Each of the two ends of the L-shaped linking bar  13  is inserted into one of the linking hole  111  of the drive body  11  and the linking hole  121  of the driven body  12 , and each of the pins  11  is inserted into one of the insertion hole  113  of the drive body  11  and the insertion hole  123  of the driven body  12 , and is inserted into the locking groove  131  of one of the two ends of the L-shaped linking bar  13 , so that the drive body  11 , the L-shaped linking bar  13  and the driven body  12  are combined with each other. Each of the multiple L-shaped drive bars  14  has two ends each inserted into one of the mounting holes  112  of the drive body  11  and one of the mounting holes  122  of the driven body  12 . When the drive body  11  is rotated, each of the multiple L-shaped drive bars  14  may be moved with rotation of the drive body  11 , thereby forming a rotation driving force to drive the driven body  12  to rotate synchronously.  
       [0005] In operation, the drive body  11  may be combined with a pneumatic tool or a motorized tool, and the driven body  12  may be combined with socket or a driver head. Thus, the drive body  11  may be rotated by the pneumatic tool or motorized tool to simultaneously rotate the driven body  12  and the socket or driver head by using the multiple L-shaped drive bars  14 . In such a manner, the socket or driver head may be used to operate a workpiece in a corner or gap having a smaller space by using the bent angle of the angled socket structure.  
       [0006] Thus, when the driven body  12  is rotated by the drive body  11 , the multiple L-shaped drive bars  14  are also driven to rotate. However, the L-shaped linking bar  13  and the multiple L-shaped drive bars  14  are exposed to the ambient environment, so that the user cannot hold the multiple L-shaped drive bars  14  to position the angled socket structure, and has to additionally provide a tool for positioning the angled socket structure, thereby causing inconvenience to the user in operation.

     [0026] The first cover  3  has a bent angle that mates with the bent angle of the angled socket  2 . The first cover  3  has two ends each provided with an outer threaded section  31  which has a distal end provided with an inner flange  311 . The first cover  3  has a mediate portion formed with an inner threaded through hole  32 .  
     [0027] The second cover  4  has a bent angle that mates with the bent angle of the first cover  3 . The second cover  4  has two ends each provided with an outer threaded section  41  which aligns with the outer threaded section  31  of the first cover  3  and has a distal end provided with an inner flange  411  aligning with the inner flange  311  of the outer threaded section  31  of the first cover  3 . The second cover  4  has a mediate portion formed with an inner threaded through hole  42  which aligns with the inner threaded through hole  32  of the first cover  3 .  
     [0028] The first nut  5  is formed with an inner threaded section  51 .  
     [0029] The second nut  6  is formed with an inner threaded section  61 .  
     [0030] The holding bar  7  has one end formed with an outer threaded section  71  that may be screwed into the inner threaded through hole  32  of the first cover  3  or the inner threaded through hole  42  of the second cover  4 , so that the holding bar  7  may be combined with the first cover  3  or the second cover  4  in a perpendicular manner.  
     [0031] In assembly, referring to FIGS.  3 - 5 , the first cover  3  and the second cover  4  are mounted on a periphery of the angled socket  2 . At this time, the inner flange  311  of the outer threaded section  31  of each of the two ends of the first cover  3  and the inner flange  411  of the outer threaded section  41  of each of the two ends of the second cover  4  are respectively inserted into the annular groove  222  of the drive body  22  and the annular groove  212  of the driven body  21 , so that the first cover  3  and the second cover  4  may be retained on the periphery of the angled socket  2 .  
     [0032] Then, the first nut  5  and the second nut  6  are mounted on the two ends of the angled socket  2 , and the inner threaded section  51  of the first nut  5  and the inner threaded section  61  of the second nut  6  are screwed on the outer threaded section  31  of each of the two ends of the first cover  3  and the outer threaded section  41  of each of the two ends of the second cover  4 , thereby fixing each of the two ends of the first cover  3  and each of the two ends of the second cover  4 , so that the first cover  3  and the second cover  4  may be combined and fixed on the periphery of the angled socket  2 , so as to encompass the angled socket  2 . Thus, the first cover  3  and the second cover  4  may function as a grip of the angled socket  2 . In addition, the outer threaded section  71  of the holding bar  7  may be screwed into the inner threaded through hole  32  of the first cover  3  or the inner threaded through hole  42  of the second cover  4 , so that the holding bar  7  may be combined with the first cover  3  or the second cover  4  in a perpendicular manner.  
     [0033] In use, referring to FIG. 6 with reference to FIGS.  3 - 5 , the combination terminal  221  of the drive body  22  of the angled socket  2  may be combined with a motorized tool “A”, and the quick connector  211  of the driven body  21  of the angled socket  2  may be combined with a driver head “B” by the fixing structure  213 . Thus, when the combination terminal  221  of the drive body  22  of the angled socket  2  is rotated, the drive bars  24  may be driven to drive the driven body  21  and the quick connector  211  of the driven body  21  to rotate, so that the driver head “B” fixed on the quick connector  211  of the driven body  21  of the angled socket  2  may also be rotated simultaneously. At this time, the user&#39;s one hand may hold the grip of the angled socket  2  formed by the first cover  3  and the second cover  4  so as to fix the position of the angled socket  2 , thereby facilitating operation of the driver head “B” in a corner or gap having a smaller space by using the bent angle of the angled socket  2 . In addition, the holding bar  7  may function as an auxiliary tool, so that the user may hole the holding bar  7  to fix the position of the angled socket  2  exactly.  
     [0034] Referring to FIGS. 7 and 8, a grip structure for fixing an angled socket  2  in accordance with a second embodiment of the present invention is shown, wherein each of the angled socket  2 , the first cover  3  and the second cover  4  has a bent angle equal 90 degrees.
