[0015] The detailed connection means are well-known in the art. The following mainly introduces the working principle and process, which are as follows:

[0016] In the present invention, the first motor 3, the second motor 6 and the electric telescopic rod 7 are all connected to the external electric control system through wires. The above devices and connection methods are all existing technologies and will not be described in detail here.

[0017] According to the instruction manual Figure 1-2It can be known that when the utility model is in use, the inner hole of the gear 13 to be processed is aligned with the position of the first top cone 8 and the second top cone 10, and the electric telescopic rod 7 is started. The telescopic end of the electric telescopic rod 7 drives the connected first top cone 8 to move in the direction of the second top cone 10, so that the ends of the first top cone 8 and the second top cone 10 are embedded in the inner hole of the gear 13 to fix the gear 13. After fixation, the edge or end face of the upper part of the gear 13 is processed.
