Detailed Description
In order to make the content of the present invention more clearly understood, the technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings.
A bolt clipper comprising: 1 blade, 2 pin shafts, 3 pressing plates, 4 bolts, 5 nuts, 6 screws, 7 nail nuts, 8 left connecting arms, 9 clamp handles, 10 rubber handles, 11 middle connecting arms, 12 right connecting arms, 13 adjusting screws, 14 elastic elements, 15 steel balls and 16 fastening screws. The middle part and the lower part of the blade 1 are respectively provided with a through hole, the side surface of the blade 1 is provided with an arc-shaped groove, the pin shaft 2 is arranged in the arc-shaped groove, the left blade 1 and the right blade 1 can flexibly rotate around the pin shaft 2, the left side of the upper part of the left connecting arm 8 is provided with the arc-shaped groove, the middle part of the arc-shaped groove is provided with the through hole, the lower part of the blade 1 is arranged in the arc-shaped groove, the blade 1 is connected with the left connecting arm 8 through 6 screws, the right side of the upper part of the left connecting arm 8 is provided with the through hole, the lower part of the left connecting arm 8 is provided with a groove, the lower part of the left connecting arm 8 is inserted into the 9 forceps handle, the 9 forceps handle is punched into the elongated groove through a punch, so that the left connecting arm 8 cannot be pulled out of the forceps handle 9, the head of the middle connecting arm 11 is provided with the through hole, the left connecting arm 8 is connected with the middle part of the connecting arm 11 through 6 screws, the middle connecting arm 11 is provided with the through 6 screws, the groove is arranged at the lower part of the middle connecting arm 11, the lower part of the connecting arm is inserted into the 9 clamp handle, the 9 clamp handle is punched into the elongated slot through a punch press, the connecting arm in the 11 clamp cannot be pulled out of the 9 clamp handle, a threaded hole is formed in the side face of the middle part of the connecting arm in the 11 clamp, 16 fastening screws are arranged in the threaded hole, a through groove is formed in the connecting arm in the 12 right connecting arm, the connecting arm in the 11 clamp is wrapped outside the through groove, a through hole is formed in the head part of the connecting arm in the 12 right connecting arm and connected with the blade 1 through 6 screws, a through hole is formed in the tail part of the connecting arm in the 12 right connecting arm and connected with the connecting arm in the 11 through 6 screws, a threaded hole is formed in the middle part of the connecting arm in the 12 right connecting arm, 13 adjusting screws are arranged in the threaded holes, a counter bore is formed in the head part of the 13 adjusting screws, 14 elastic elements are arranged in the counter bore, one end of the 14 elastic elements is in contact with the counter bore in the 17 adjusting screw head part, one end is in contact with 15 steel balls, and the connecting arm in contact with the 11 steel balls.
