Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As fig. 1, as shown in fig. 2, this motor end cover jump ring erecting tool, guide bar 1 and the sleeve that the cover just can reciprocate on locating guide bar 1 including supplying a plurality of jump ring movable mounting, guide bar 1 is by being round platform column structure setting and being used for supplying the jump ring to strut and the installation department 3 of installation and supplying the spacing portion 4 of sleeve 2 sliding fit to constitute, be provided with between spacing portion 4 one end and the sleeve 2 bottom and supply the reset spring 5 that sleeve 2 elasticity resets, be located and be provided with on the 3 bottoms of installation department and cooperate and be used for the location structure of guide bar 1 location with motor end cover draw-in groove, and be located that spacing portion 4 serves and set up the centre bore 6 that supplies reset spring 5 fixed mounting.

Further saying in detail, location structure comprises the bellying 7 that is located 3 bottom centers of installation department and outside bellied and the locating ring groove 8 that is located 3 bottoms of installation department and is used for the guide bar 1 location, bellying 7 and motor end cover center pin hole looks adaptation, and 8 notch widths of locating ring groove slightly big and motor end cover center pin hole inner wall and the width between the draw-in groove inside wall.

In further detail, the installation part 3 and the limiting part 4 are arranged in an integrated structure, a gap for the sleeve 2 to move up and down is formed between the inner peripheral wall of the sleeve 2 and the outer peripheral wall of the guide rod 1, and an opening of the inner peripheral wall of the sleeve 2 is in a horn structure and is matched with the installation part 3.
