[0002] Motor, commonly known as "motor", refers to an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction. The motor includes multiple parts such as rotor, stator and winding. During the production process of the motor, the copper wire in the winding needs to be inserted and then the copper wire ends are welded. Since the wire ends in the winding are relatively soft, they need to be manually clamped with tools such as pliers and then welded. However, there are many wire ends in the winding and they are messy. They need to be constantly combed and repeatedly clamped with tools, which is very troublesome. Utility Model Content

After the wire ends are clamped and fixed in order, you only need to use a welding machine to weld the two wire ends on the clamping assembly together.

[0026] The thread end is placed in the clamping groove, and the thread end is located between the clamping plate 6 and the inner ring 2. By rotating the threaded rod 8, the clamping plate 6 is moved close to the inner ring 2 and cooperates with the inner ring 2 to clamp the thread end.

[0028] By rotating the swivel 10, the swivel 10 will use the arc groove 17 to drive each arc plate to move away from or closer to the inner ring 2 at the same time, so that the thread ends clamped on each mounting plate 7 can be loosened at the same time, wherein the arc center of the arc groove 17 deviates from the axis of the swivel 10; wherein, the swivel 10 will be provided with corresponding components to limit the rotation of the swivel 10 (such as increasing the friction of the rotation of the bearing seat on the swivel 10, or opening a screw hole on the swivel 10 and threading the screw, and then using the end of the screw to resist and squeeze the outer ring 3, thereby increasing the friction of the rotation of the swivel 10). The above method is to prevent the swivel 10 from loosening, and the above method is a prior art means, and the specific structure and method, as well as the drawings, are not described.

[0033] The base 13, the fixing rod 5 and the connecting rod 4 are used to adjust the height of the device body 1 so that the clamping position of the device body 1 just adapts to the height at which the motor wire end is clamped.

[0034] like Figure 1As shown, in some embodiments, the limiting assembly includes a pin 12 slidably connected to a socket opened on one side of the fixing rod 5, and the connecting rod 4 is provided with pin slots 11 distributed in a linear array and plugged into the pin 12;

[0035] By lifting the connecting rod 4 and making the corresponding pin groove 11 on the connecting rod 4 parallel to the socket, and then inserting the pin 12 into the socket and the pin groove 11, the rod 5 and the connecting rod 4 can be firmly fixed.
