On individual suspension ring, and suspension ring are limited in suspension ring hanging hole by spacer pin, be correspondingly arranged on the upside of described crescent lock ring
Oil scraper ring, oil scraper ring is arranged in elevator body by interference fit made of rubber, the structure bag of described lock ring handle
Slide bar and sliding sleeve are included, slide bar is inserted into sliding sleeve, and the end of slide bar is fixedly connected on crescent lock ring after passing through described chute
On, the width of chute is equal to the diameter of slide bar, and spring is cased with slide bar, and described sliding sleeve has to elevator under the action of the spring
The close trend of main body, the both ends of described chute are each provided with a lock hole to match with the diameter of described sliding sleeve,
When at lock ring handle motion to described lock hole, in described sliding sleeve insertion lock hole, the upper end of described spacer pin is set
There is the link made of steel wire, magnet is cased with the middle part of link.
Described crescent lock ring is made of copper.
Two end sets of described chute have the guiding surface for guiding sliding sleeve to be skidded off out of lock hole.
The beneficial effects of the utility model are：The utility model can have by setting oil scraper ring in the upside of elevator body
Effect prevents greasy filth from entering around crescent lock ring, so as to avoid the generation of catching phenomenon.The utility model has by setting
The lock ring handle of flexible stretching structure so that lock ring handle may be locked in two extreme positions, so as to improve lock ring in pole
Positional stability during extreme position, the uncontrolled movement of crescent lock ring is avoided, eliminates potential safety hazard.
