Specific implementation mode
Technical scheme of the present invention and advantageous effect are further illustrated in the following with reference to the drawings and specific embodiments.
Referring to attached drawing 1 to attached drawing 3, the cut spring suitable for small-sized installation space of the invention, including it is outer sleeve 7, interior
One end of sleeve 6 and spring 5, inner sleeve 6 is fixed with end 4, and the other end can be inserted in outer sleeve 7, the interposition of outer sleeve 7
The outside set is fixed with ring flange 71, and outer sleeve 7 and each comfortable end set of inner sleeve 6 have a locking pin hole, interior under assembled state
One end of sleeve 6 is sleeved in outer sleeve 7, and spring 5 is sleeved on the outside of outer sleeve 7, and spring 5 is in compressive state, and one end is against
On end 4, the other end is against on ring flange 71, and the locking pin hole in the locking pin hole and inner sleeve 6 on outer sleeve 7 overlaps,
Locking pin 8 is installed in locking pin hole.
Referring to attached drawing 2, ring flange 71 is arranged in the outside in the centre position of outer sleeve 7 cut spring of the invention, makes
Obtaining outer sleeve 7 can be through walls, i.e., across spring assembly mounting bracket 10, so as to utilize 10 lower section of spring assembly mounting bracket
Space.
In the case of 7 setting through walls of outer sleeve of the present invention, locking pin 8 needs to set across spring assembly mounting bracket 10
It sets in the lower section of holder 10, referring to attached drawing 3, to need to open up the lock passed through for the both ends of locking pin 8 in mounting bracket 10
