Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides a technical solution: the utility model provides a telescopic connection rim, includes fixed frame 1, installing frame 2 and connecting

piece

3, and 3 evenly distributed of a plurality of connecting pieces are on fixed frame 1, and connecting piece 3 includes pullover 31, sleeve 32, round pin axle 33 and spring 34.

Wear to locate fixed plate 11 of fixed frame 1 lower extreme on the pullover 31, sleeve 32 locates fixed plate 11 inboard and cover and establishes on pullover 31, and pullover 31 and sleeve 32 pass through threaded connection, and the tip of sleeve 32 is concave to be equipped with and is used for rotatory fixed drive groove 321, can be rotatory sleeve 32 with screwdriver embedding drive groove 321, makes pullover 31 and sleeve 32 fix on fixed plate 11, dismantles simply, can change at any time when the part damages, and cost of maintenance is low. The pin shaft 33 penetrates through the sleeve head 31, one end of the pin shaft 33 is arranged in the sleeve head 31 and sleeved with the spring 34, the end portion, close to the sleeve head 31, of the pin shaft 33 is convexly provided with a limiting block 331 for preventing the pin shaft 33 from popping out of the sleeve head 31, the end portion of the spring 34 is connected with the limiting block 331, one end, far away from the pin shaft 33, of the spring 34 is connected with the bottom of the inner cavity of the sleeve 32, and the limiting block 331 and the inner wall of the inner cavity of the sleeve 32 form an extrusion.
