[0029] As a preferred embodiment, the connecting assembly 3 includes an external thread block 301, a fixed block 302, an internal thread groove 303, a connecting groove 304, a connecting spring 305, a connecting slider 306 and a connecting block 307; the external thread block 301 is fixedly connected to the end of the transmission shaft 206; the fixed block 302 is fixedly arranged on the groove slope grinding block 102; the fixed block 302 is provided with an internal thread groove 303 on the side away from the groove slope grinding block 102; the external thread block 301 is threadedly connected to the internal thread groove 303; a connecting groove 304 is provided in the transmission shaft 206; one end of the connecting spring 305 is fixedly connected to the inner wall of the connecting groove 304; the connecting slider 306 slides It is movably arranged in the connecting groove 304, and the connecting slider 306 is fixedly connected to the other end of the connecting spring 305; five connecting blocks 307 are fixed in a ring array on the side of the connecting slider 306 away from the connecting spring 305, and the ends of the connecting blocks 307 extend to the outside through the connecting groove 304; the connecting blocks 307 are a truncated cone structure with a larger upper part and a smaller lower part, which can not only improve the connection strength between the connecting blocks 307 and the connecting slider 306, but also reduce the contact area between the connecting blocks 307 and the fixed block 302, thereby reducing the rotational resistance of the connecting blocks 307 to the fixed block 302; the connecting blocks 307 are in contact with the fixed block 302. When the groove slope grinding block 102 is replaced, the groove slope grinding block 102 is rotated to thread the external thread block 301 into the internal thread groove 303, and the fixing block 302 is moved away from the transmission shaft 206, so that the connecting spring 305 is no longer stressed and begins to stretch, so that the connecting slider 306 slides in the connecting groove 304, and the connecting block 307 moves until the external thread block 301 and the internal thread groove 303 are no longer connected.

At this time, the connecting spring 305 returns to its original shape, and the disassembly is completed. When installing, the external thread block 301 and the internal thread groove 30 3, and the fixing block 302 moves toward the direction of the transmission shaft 206, so that the fixing block 302 presses the connecting block 307, so that the connecting block 307 moves in the opposite direction, so that the connecting slider 306 slides in the opposite direction in the connecting groove 304, so that the connecting spring 305 is forced to contract until the side surface of the fixing block 302 contacts the side surface of the transmission shaft 206. At this time, the connecting spring 305 no longer contracts, and the relative force generated by the contraction of the connecting spring 305 makes the threaded connection between the external thread block 301 and the internal thread groove 303 more stable.
