The upper surface of the right end of the travel groove 1021 is provided with a travel notch 1023 with the same shape and size as the fixed seat 402.
The working principle is as follows: when the shaft end of the transmission shaft is ground, the transmission shaft is fixed by the locking piece 404 and the driving motor 403 and the grinding piece 307 are electrified to work. An operator presses down the sanding part 307 through the lifting handle 3071, when the sanding part 307 is pressed down, the connecting rod 306 drives the sliding plates 305 in the left support part 301 and the right support part 302 to press the compression spring 304, and meanwhile, the connecting rod 306 drives the transmission crankshaft 501 to move downwards along the limiting frame 3022.

In addition, in order to be suitable for grinding shaft ends of transmission shafts with different lengths, the sliding stroke of the sliding bottom plate 401 of the fine adjustment assembly in the sliding groove 201 can be adjusted. When a transmission shaft with short length is ground, the fine adjustment screw rod 504 is screwed, the fine adjustment screw rod 504 generates thrust on the sliding bottom plate 401 through the combined action of the thread groove 2012 in threaded connection with the fine adjustment screw rod, the sliding bottom plate 401 is pushed to slide towards the lifting assembly, and the distance from the locking piece 404 to the lower part of the grinding piece 307 is shortened; similarly, when the transmission shaft with a long length is polished, the fine adjustment screw rod 504 is loosened, the fine adjustment screw rod 504 generates pulling force on the sliding bottom plate 401 through the combined action with the thread groove 2012, the sliding bottom plate 401 is pushed to slide back to the lifting assembly, and the distance from the locking member 404 to the lower part of the polishing part 307 is increased.
