Fixed gear along lock gear supporting member turn round when so that lock gear is away from lock gear supporting member, in lock gear
External tooth form engaged with the internal tooth form of retainer, lock gear is locked, and resetting spring returns to initial position at this time, and gear reaches
To the purpose of locking.
In a kind of above-mentioned locking gear, the resetting spring bends setting, and the beginning of resetting spring in the shape of a spiral
End is both provided with the card for resetting spring positioning with end.The fixation of resetting spring is used to help, prevents resetting spring from occurring
The phenomenon of dislocation, influences its normal function.
In a kind of above-mentioned locking gear, the cam receptacle of the gear mass is provided with its circumference for solid
Determine the spring fixing groove of resetting spring beginning card.
There is the axis hole passed through for shaft in a kind of above-mentioned locking gear, at the center in the optical axis portion, it is described
Axis hole in the starriness of rule, and there is the fixation notch stretched into for resetting spring end card on its end face.
In a kind of above-mentioned locking gear, the lock gear supporting member includes：For lock gear movement
Slide support surfaces, and it is used to support when lock gear is released the barrier support surface of lock gear, the slip
Support surface passes through arc transition corner with barrier support surface.
In a kind of above-mentioned locking gear, the retainer is provided outside fixing sleeve, the fixing sleeve and holding
Frame outer surface fits.Prevent in work operating engineering, phenomena such as retainer loosens produces, and improves its stability.
Compared with prior art, this locking gear in the inside of gear mass by setting brake cam with lock gear come real
The locking of existing gear mass, the resetting spring being provided with more rapidly can efficiently realize locking, and there is easily locking, performance to stablize
The advantages of.
