Detailed description of the invention
The embodiment combined in accompanying drawing is further described by the present invention below:
As shown in Fig. 1 ~ 9, the invention mainly comprises manual clutch handle 2 and clutch mainboard 3, the bearing bore that clutch mainboard 3 is through before and after being provided with, it is provided with clutch shaft bearing 4 in bearing bore.
Clutch shaft bearing 4 center is provided with clutch block installation cavity, is provided with clutch block 6 in clutch block installation cavity, and clutch block 6 both sides are provided with clutch block gear foot 7.Clutch shaft bearing 4 clutch mainboard 3 side dorsad is provided with two bearing grooves 5.The clutch block gear foot 7 of clutch block 6 both sides is positioned at two bearing grooves 5, and clutch block gear foot 7 is stopped by clutch shaft bearing 4 cannot be to clutch mainboard 3 one lateral movement, it is possible to clutch mainboard 3 one lateral movement dorsad.
Clutch shaft bearing 4 is provided with cam 9 in clutch mainboard 3 side dorsad, cam 9 center is provided with cam sleeve 10 towards Engaging-and-disengaging bearing seat 4 side, being provided with spring 8 in cam sleeve 10, spring 8 end thereof contacts cam 9, clutch block 6 is pressed in the clutch block installation cavity of clutch shaft bearing 4 by the other end.Described cam sleeve 10 both sides are provided with the sleeve clutch groove 11 that clutch block gear foot 7 can be allowed to enter smoothly.
Under electric clutch state, clutch shaft bearing 4 connects drive by the electric driving mechanism 1 being arranged on clutch mainboard 3, and cam 9 is rotated with clutch shaft bearing 4 by clutch block 6.Described electric driving mechanism 1 includes that motor 1.1, motor 1.1 outfan are provided with drive sprocket 1.2, and drive sprocket 1.2 connects drive by driving chain 1.3 and is arranged on the driven sprocket 1.4 of clutch shaft bearing 4 outer ring.
Under manual clutch state, manual clutch handle 2 stretches into through clutch mainboard 3 in the clutch block installation cavity of clutch shaft bearing 4, overcomes spring 8 pressure to be pressed in the cam sleeve 10 of cam 9 by clutch block 6.Manual clutch handle 2 front end is provided with manual clutch fixture block 13, and while pressure clutch block 6, manual clutch fixture block 13 enters sleeve clutch groove 11, thus manually clutch handle 2 band moving cam 9 rotates.Manual clutch handle 2 rear end is provided with the handle 12 vertical with manual clutch handle 2, is convenient for people to rotate dynamic clutch handle 2 and carries out manual clutch.
