When the ends of the first cutter handle 23 and the second cutter handle 24 gradually extend into the closing groove 2521, the first cutter handle 23 and the second cutter handle 24 gradually close under the guidance of the closing groove 2521, thereby controlling the clamping of the first cutter head 21 and the second cutter head 22. When the cylinder 251 retracts, the piston 252 resets under the rebound of the elastic body 253.

[0117] Specifically, the closing groove 2521 is a conical or frustum-shaped groove, and the ends of the first tool holder 23 and the second tool holder 24 are adapted to the shape of the closing groove 2521.

[0118] In this embodiment, the first cutting head 21 is provided with a first shearing part 211 and a first clamping part 212;

[0119] The second cutter head 22 is provided with a second shearing part 221 and a second clamping part 222. The first shearing part 211 corresponds to the second shearing part 221, and the first clamping part 212 corresponds to the second clamping part 222.

[0120] A clamping gap 27 is formed between the first cutting part 211 and the second cutting part 221 to clamp the wire end when the first cutting head 21 and the second cutting head 22 come together.

[0121] A clamping gap 28 is formed between the second clamping part 222 and the second clamping part 222 to clamp the wire end when the wire end is clamped by the clamping gap 27.

[0122] Specifically, the first clamping part 212 and the first shearing part 211 are arranged in parallel, and the second clamping part 222 and the second shearing part 221 are arranged in parallel.

[0123] In this embodiment, the clamping gap 27 is smaller than the clamping gap 28 in the same state.

[0124] In this embodiment, both the first shearing section 211 and the second shearing section 221 are provided with shearing V-tooths 2111. The shearing V-tooths 2111 on the first shearing section 211 and the shearing V-tooths 2111 on the second shearing section 221 are arranged opposite to each other, and a clamping gap 27 is formed between the shearing V-tooths 2111 on the first shearing section 211 and the shearing V-tooths 2111 on the second shearing section 221. The arrangement of the shearing V-tooths 2111 on the first shearing section 211 and the shearing V-tooths 2111 on the second shearing section 221 allows for more effective clamping of the wire when they come together. In other implementations, shearing V-tooths 2111 may be provided only on one of the first shearing section 211 and the second shearing section 221.

[0125] In this embodiment, either the first clamping part 212 or the second clamping part 222 is provided with a clamping V-tooth 2121, and the other is provided with a clamping plane 2221. A clamping gap 28 is formed between the clamping V-tooth 2121 and the clamping plane 2221. This arrangement of one clamping V-tooth 2121 and one clamping plane 2221 can clamp the wire end more stably. In other implementations, both the first clamping part 212 and the second clamping part 222 may be clamping planes 2221, or both may be clamping V-tooth 2121.

[0126] In this embodiment, a first V-groove 213 is formed between the clamping V-tooth 2121 and the shearing V-tooth 2111 on the first cutter head 21; a second V-groove 223 is formed between the clamping plane 2221 and the corresponding shearing V-tooth 2111 on the second cutter head 22.

[0127] In this embodiment, the clamping scissor head also includes a first handle 23 and a second handle 24. The first handle 23 is fixed to the first cutter head 21, and the second handle 24 is fixed to the second cutter head 22. The joints between the first cutter head 21 and the first handle 23, and between the second cutter head 22 and the second handle 24, are hinged. The opening and closing of the first cutter head 21 and the second cutter head 22 can be controlled by opening and closing the first handle 23 and the second handle 24. Specifically, return springs can also be provided at the joints between the first cutter head 21 and the first handle 23, and at the joints between the second cutter head 22 and the second handle 24, to assist in resetting and separating the two cutters after the first cutter head 21 and the second cutter head 22 have completed cutting.

[0134] In this embodiment, the fixture body 11 is provided with a mounting boss 112, and a disassembly groove is provided on the mounting boss 112; and a clearance groove 1121 communicating with the disassembly groove is also provided on the side of the mounting boss 112. Specifically, there are multiple mounting bosses 112, and multiple disassembly grooves are respectively provided on the mounting bosses 112.

[0135] In this embodiment, a support groove 113 is provided on the side of the fixture body 11 away from the disassembly groove, and the disassembly groove extends into the support groove 113.

[0136] The positioning clamp 1 also includes a support member 13 for supporting the end of the bearing portion 1211. The support member 13 is detachably disposed in the support groove 113 and corresponds to the disassembly groove. When the bearing portion 1211 of the bearing member 121 is inserted into the disassembly groove, the support member 13 can support the end of the bearing portion 1211.

[0137] In this embodiment, the positioning fixture 1 further includes a wire clamping assembly 14 for clamping the leads of the coil product. The wire clamping assembly 14 is disposed on the fixture body 11 and corresponds to the position of the carrier assembly 12. The wire clamping assembly 14 enables the positioning fixture 1 to not only position the coil product but also clamp and position the leads of the coil product.

[0138] In this embodiment, the wire clamping assembly 14 is detachably mounted on the fixture body 11, and the wire clamping assembly 14 can be disassembled and replaced as needed.

[0139] In this embodiment, the wire clamping assembly 14 includes a wire clamping base 141, a rubber ring 142, a fixing screw 143, and a fixing nut 144. The wire clamping base 141 is disposed on the fixture body 11, the rubber ring 142 is disposed on the wire clamping base 141, and the fixing screw 143 passes through the wire clamping base 141 and the rubber ring 142 in sequence and is movably connected to the fixing nut 144.
