Specific embodiment
The present invention includes organic frame 19, and rotatable pressure knot axis 15 is provided in the rack 19, and the pressure knot axis 15 is logical
The connection pressure knot roller 2 of over-voltage knot arm 10, the pressure knot roller 2 are operated synchronously in company with pressure knot axis 15；
It is provided on the pressure knot axis 15 and controls the brake gear that the pressure knot axis 15 operates, the brake gear includes to embrace
The brake disc 16 of the pressure knot axis 15, the brake disc 16 are formed with the cavity for accommodating the pressure knot axis 15, the brake gear
It is additionally provided with the driving device for changing the cavity size, presses knot axis 15 to be held tightly or be released to realize.
The driving device includes the brake ribbon 14 being arranged in outside the brake disc 16, and the brake ribbon 14 drives the brake
The operating of hull 16 is provided with outside the brake ribbon 14 to change the space size that brake disc accommodating pressure ties axis 15 and compresses the brake
The chain 13 of vehicle band 14.
Described 13 one end of chain is connected on pin shaft 12, and the other end of the chain 13 is connected on chain connecting block 17；
The pin shaft 12 connects a roller 4 by brake swing rod 3, is provided with cam 5 and the cooperation of the roller 4 realizes 4, roller
The variation set；
