Referring to fig. 9, fig. 9 is a schematic structural diagram of an embodiment of a bending tool of the tool assembly shown in fig. 1.

In an embodiment, the tool assembly further comprises a bending tool 03, the bending tool 03 comprising: a first clamping member 031, the first clamping member 031 comprising a first clamping portion 0311 and a shaft 0312 connected; a second clamping member 032, wherein the second clamping member 032 comprises a second clamping part 0321 and a shaft housing 0322 which are connected; wherein, axostylus axostyle 0312 of first holder 031 imbeds in the axle housing 0322 of second holder 032 to axostylus axostyle 0312 can be relative axle housing 0322 along axial displacement, in order to drive first clamping part 0311 of first holder 031 and the second clamping part 0321 of second holder 032 and remove each other in opposite directions, in order to wait to bend from the relative both sides cooperation centre gripping of waiting to bend respectively, and then bend the piece of waiting to bend of centre gripping.

Further, the first clamping portion 0311 includes a first abutting portion 03111 and a second abutting portion 03112 that extend in different directions and are connected, the first abutting portion 03111 is connected to the shaft 0312, the second abutting portion 03112 is away from the shaft 0312 relative to the first abutting portion 03111, and the second abutting portion 03112 is away from the shaft housing 0322 relative to the second clamping portion 0321.

Referring to fig. 9 and 10, fig. 10 is a schematic structural view of a portion of the bending tool shown in fig. 9.

Further, bending tool 03 still includes elastic component 033, and elastic component 033 one end and axostylus axostyle 0312 are relatively fixed, and the other end and the tip that second clamping part 0321 was kept away from to axle housing 0322 are relatively fixed, wherein elastic component 033 is in the compression state when first clamping part 0311 and second clamping part 0321 cooperate the centre gripping to wait to bend. At the end of the bending process, the elastic member 033 is restored to the original state before clamping by the first clamping portion 0311 and the second clamping portion 0321.

Please continue to refer to fig. 9 and 10. The end of the second clamping portion 0321 close to the second abutting portion 03112 extends in a direction away from the first abutting portion 03111 to form a slit 0323 between the second clamping portion 0321 and the first abutting portion 03111, i.e., the end of the second clamping portion 0321 close to the second abutting portion 03112 is slightly tilted to form a slit 0323. Wherein after the slit 0323 is engaged with a to-be-bent member, the slit 0323 can limit the elastic member to drive the first clamping portion 0311 and the second clamping portion 0321 to move away from each other, so as to complete the bending of the workpiece in the state of holding the workpiece.

Specifically, the application process of the bending tool in the embodiment may be as follows: the user drives the second clamping portion 0321 and the first abutting portion 03111 to approach each other, the elastic member 033 is compressed, and after the member to be bent is clamped into the slit 0323 between the second clamping portion 0321 and the first abutting portion 03111, the user starts to bend the member to be bent by the bending tool. The friction between the bent piece and the second clamping portion 0321 in the slit 0323 is enough to limit the elastic piece 033, so that the elastic piece 033 does not drive the first clamping portion 0311 and the second clamping portion 0321 to move back to each other and reset. After the bending is completed, the part to be bent is separated from the slit 0323, and the first clamping portion 0311 and the second clamping portion 0321 are reset under the action of the elastic restoring force of the elastic part 033. The slit 0323 between the second clamping portion 0321 and the first abutting portion 03111 can be conveniently clamped with a to-be-bent member, so that the bending action of the bending tool is facilitated.

Please continue to refer to fig. 10. In an embodiment, a sliding groove 03211 is disposed beside the second clamping portion 0321, and the first abutting portion 03111 is slidably supported in the sliding groove 03211 for guiding the first clamping portion 0311 and the second clamping portion 0321 to move toward each other, wherein the sliding groove 03211 is disposed far away from the slit, so as to prevent the slit 0323 from not playing a role of clamping the to-be-bent piece.

Please continue to refer to fig. 9. In an embodiment, a guide hole 03221 extending in an axial direction is formed in the shaft housing 0322, the shaft rod 0312 is inserted into the guide hole 03221, the shaft rod 0312 is fixedly provided with a guide block 03121, and a cross section of the guide block 03121 and a cross section of the guide hole 03221 are engaged with each other to guide the shaft rod 0312 to move along the guide hole relative to the shaft housing 0322.

Further, one end of the elastic member 033 is fixed to the guide block 03121 of the shaft 0312.
