One end of described spring is fixed on the spring housing, and the other end is connected with the projection of lock sleeve.
The upper end of described lock sleeve is provided with draw ring, between draw ring and the lock sleeve back-up ring is set.
The present invention is used in thin take-up axle head, and the top is fixed, and take-up reel is more stable, can not become flexible.
Description of drawings
Fig. 1 is a structural representation of the present invention
Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure: locking device comprises lock sleeve 1, back-up ring 2, draw ring 3, spring housing 4, top 5, spring 6, locking ball 7, take-up axle 8 etc.
The present invention adopts to put at take-up axle 8 external fixation and is provided with toply 5, and described top 5 upper end is provided with stepped hole, and the side of described stepped hole is a taper seat; Fixedly connected with spring housing 4 in top 5 top, in spring housing 4, be provided with lock sleeve 1, the upper end of lock sleeve 1 is provided with draw ring 3, between draw ring 3 and the lock sleeve 1 back-up ring 3 is set, the bottom of lock sleeve 1 is provided with two projectioies, be respectively equipped with several locking balls 7 in the bottom of described projection, the stepped hole of locking ball 7 and top 5 closely cooperates at the step place; The top of spring housing 4 and lock sleeve 1 interference fit form a space between the bottom of spring housing 4 and the lock sleeve 1, spring 6 is set in described space, and an end of spring 6 is fixed on the spring housing 4, and the other end is connected with the projection of lock sleeve 1.
The present invention when locking ball 7 is in the step place of top 5 stepped holes, locks ball 7 and closely cooperates with top 5 in use, can lock take-up axle 8; When pulling draw ring 3, locking ball 7 is up moved along the inclined-plane of stepped hole, thereby can decontrol locking take-up axle 8.
