Benefits of technology

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: When using this utility model, the end of the lead wire body that needs to be looped is passed from front to back through the U-shaped clamp, two limiting rollers, and then through the space between the shaft roller and the force roller. The two limiting rollers are adjusted by adjusting the front and rear positions of the slider on the slide rail, and then fixed with fixing screws. Then, the U-shaped clamp is placed in front of the limiting rollers, thereby adjusting the looping point of the lead wire body by adjusting the position of the limiting rollers. Turning the handle drives the top plate to rotate, and the spline shaft at the bottom of the top plate drives the round block to rotate through the spline groove. The elastic tab on the outer side of the round block cooperates with the inner ratchet groove to achieve unidirectional rotation. By rotating the top plate, the force roller is driven to rotate to apply extrusion force to the lead wire body. The lead wire body is bent and shaped along the outer edge contour of the shaft roller. Then, the end of the lead wire body is inserted into the U-shaped clamp for fixing, thereby achieving looping. The looping efficiency is high, saving time and effort.
