Specific implementation mode
The specific implementation mode of the present invention is described in further detail below.
As shown in Figs. 1-2, the present invention includes
Installation axle 2 equipped with mounting hole 1, the installation axle 2 is for being detachably secured to engine；
The rotary body 4 being rotatably connected in the installation axle 2；
Belt pulley 6 that is eccentric and being rotatably installed on the rotary body 4,
It is characterized in that,
The bottom of the rotary body 4 is equipped with mounting hole 8, which is blind hole；
It is removably fixed with rotation limiter 10 in the installation axle 2；
The inner wall of the mounting hole 8 is continuous and has been equidistantly positioned at least one section unidirectional tooth 12；
The outer circumference surface of the rotation limiter 10 is equipped with and is contacted with the unidirectional tooth 12, and for limiting the rotation
Body 4 is only capable of doing the pawl 13 of single direction rotation.
As a further improvement on the present invention, the rotation limiter 10 includes：
The limitation matrix 14 being detachably fixed in the installation axle 2；And
The limitation set 16 being rotatably mounted on the limitation matrix 14, the pawl 13 are mounted on limitation set 16；
Annular groove 18 in 14 upper surface of the limitation matrix is set, and the annular groove 18 is same with the limitation matrix 14
The heart；
Convex block 19 on the limitation set 16 is set, and the convex block 19 being capable of the sliding in the annular groove 18.
As a further improvement on the present invention, the radian value of the annular groove 18 is between 0 to 1/6 π.
As a further improvement on the present invention, further include a rolling bearing 20, the inner ring of the rolling bearing 20, which is fixed, pacifies
