In the above scheme, the outer cylinder 10 is equivalent to a support, the motor base to be processed is clamped and fixed by the pipe end of the inner circular pipe 50 arranged on the outer cylinder and the circular ring 30, specifically, the pipe end of the inner circular pipe 50 is clamped on the lug 5 at one end of the motor base to be processed, the circular ring 30 is clamped on the lug 4 at the other end of the motor base to be processed, and the end surface 1 to be processed, the front spigot 2, the rear spigot 2 and the iron core stop 3 can be processed under the condition of one-time clamping. The distance between the pipe end of the inner circular pipe 50 and the circular ring 30 is in adjustable locking fit, namely the distance between the pipe end of the inner circular pipe 50 and the circular ring 30 is required to be axial and can be changed relatively, when the distance between the pipe end of the inner circular pipe 50 and the circular ring 30 is increased to the axial length of the motor base, the base blank can be placed into the area 40, then the distance between the pipe end of the inner circular pipe 50 and the circular ring 30 is reduced, the pipe end of the inner circular pipe and the circular ring are clamped on the lug lapping lug 4 respectively, the axial clamping locking force is ensured, and at the moment, cutting can be carried out. After the cutting is completed, the end of the inner circular tube 50 is axially displaced and separated from the annular ring 30, and the engine base can be taken out.

In order to realize that the distance between the pipe end of the inner circular pipe 50 and the circular ring 30 is adjustable, there are several preferred schemes, one is that the outer cylinder 10 is in axial displacement fit with the inner circular pipe 50, and the outer cylinder 10 is in circumferential limit fit with the inner circular pipe 50, at this time, the circular ring 30, the end part of the outer cylinder 10 and the two connecting arms 20 are in an integral fixed connection structure; secondly, the outer cylinder 10, the inner cylinder 50 and the connecting arms 20 are of an integrated structure, and the circular ring 30 is axially and movably connected with the two connecting arms 20. The two schemes can realize the purpose that the distance between the pipe end and the circular ring 30 is adjusted to fix and position the added machine base to be processed by the fixing clip.
