Referring to fig. 1 to 6, a pin bending mechanism according to the present invention will be described. The utility model provides a pin mechanism of bending, including centre gripping subassembly 20 and the subassembly 30 of bending, centre gripping subassembly 20 is used for 1 pin of centre gripping electron device, and is fixed with electron device 1, and the subassembly 30 of bending is used for bending 1 pin of electron device, makes 1 pin of electron device buckle. The clamping assembly 20 comprises a positioning block 21 and a pressing block 22, the pressing block 22 is arranged opposite to the positioning block 21, the pressing block 22 is used for being matched with the positioning block 21 to clamp the pin of the electronic device 1, and the pin of the electronic device 1 is clamped between the positioning block 21 and the pressing block 22.

When the first driving member 32 moves, the connecting arm 33 is driven to rotate along the hinge position with the mounting seat 31, so that the connecting arm 33 swings. The bending piece 34 is installed on the connecting arm 33, and the bending piece 34 is located on one side of the positioning block 21 close to the pressing block 22. When the connecting arm 33 rotates, the bending piece 34 can be driven to move circularly, and then the pin is pushed towards the pin bending direction, so that the pin is pressed downwards, and the pin is bent downwards. Namely: the bending piece 34 performs circular motion, and not only has displacement in the horizontal direction to generate thrust in the horizontal direction to the pins, but also has displacement in the vertical direction to generate thrust in the vertical direction to the pins. Therefore, in the pin bending process, the bending piece 34 always has bending thrust on the pin, so that the pin is bent. The bending piece 34 moves towards the fixed end of the pin in the pin bending process; when the bending piece 34 just contacts the pin, the position of the bending piece 34 is far away from the positioning block 21, and the contact positions of the bending piece 34, the positioning block 21 and the pin have a certain distance in the length direction of the pin, so that the extrusion effect on the edge position of the pin close to the positioning block 21 is reduced; when the pin is bent, the bending piece 34 moves towards one side of the fixed end of the pin, so that the acting force of the bending piece 34 on the surface of the pin along the length direction of the pin is reduced, namely, the cutting action of the bending piece 34 on the pin is reduced. Meanwhile, the weakening of the extrusion effect can cause the pressure of the bending piece 34 on the surface of the pin to be smaller, and further greatly weaken the cutting effect of the bending piece 34 on the pin.
