[0029] The specific implementation process is as follows: The driving shaft assembly 1, the roller assembly 2, and the driven shaft assembly 3 are coaxially connected and axially locked with the locking screw 7; the lock nut 6 coaxially and tightly fixes the locking spacer 5 in the driven shaft assembly 3 by using the thread on the locking screw 7. A number of threaded holes a8 are evenly arranged on the outer end face of the locking spacer 5 along the circumferential direction of the shaft; the counterweight block a10 is locked by screwing the set screw a9 with the lock washer a11 through the countersunk round through hole a12 into the threaded hole a8 on the outer end face of the locking spacer. Then, the snap ring a14 is installed in the groove a13 on the side wall of the countersunk head to further prevent the set screw a9 from loosening; stop grooves 18 and counterweight block inlets 19 are respectively formed at the left and right ends of the roller core 16. A number of threaded holes b17 are evenly arranged on the bottom of the stop groove 18 along the circumferential direction of the shaft. After the counterweight block b20 slides through the counterweight block inlet 19 to the designated position in the stop groove 18, the set screw b23 with the lock washer b25 is screwed through the countersunk round through hole b22 into the threaded hole b17 of the roller core for locking; then, the snap ring b24 is installed in the groove b21 on the side wall of the countersunk head to further prevent the set screw b23 from loosening. The counterweight block a and the stop groove have various forms. In this embodiment, the counterweight block a is given as a cylindrical shape (such as Figure 2 ), and for the stop groove, a dovetail shape ( Figure 6 ) and a T-shaped ( Figure 7 ) are respectively given.
