Detailed Description

The technical solution of the present invention will be further described in detail with reference to the following detailed description, but the present invention is not limited thereto.

Referring to fig. 1-7, the utility model discloses a gas of bounce-back formula props structure, support 1 including gas, still include bounce-back ware 3, the pressure cylinder end that gas supported 1 is equipped with supports head 2, support head 2 and gas and support 1 and connect soon, support head 2 and bounce-back ware 3's shell is articulated, and support head 2 still with bounce-back ware 3 press the cooperation installation of pole 16, support head 2 direct action and press pole 16, can compress to the shortest point and lock extremely according to pole 16, press once more and can touch bounce-back ware 3, press pole 16 and will support head 2 and push away. The terminal universal slewing mechanism 14 that is equipped with of bracing piece that the gas was supported 1, universal slewing mechanism 14 is equipped with spherical joint 13 including rotating base 4 and axis of

rotation

5, and 5 tops of axis of rotation are equipped with, and spherical joint 13 and the cooperation installation of rotating base 4, and spherical joint 13 can be around rotating base 4 free rotation.

Preferably, one side of the rebounder 3 is provided with a hinge base 6, the hinge base 6 is hinged with the end part of the support head 2, and the air support 1 can rotate around the hinge part. One side of the supporting head 2 close to the rebounder 3 is provided with a convex block 8, and the convex block 8 is matched with a pressing rod 16 of the rebounder 3. When the air support 1 rotates around the hinge close to the rebounder 3, the convex block 8 can gradually extrude the pressing rod 16 of the air support 1 until the pressing rod 16 contracts to the locking position, then the rebounder 3 can be triggered by pressing again, the convex block 8 is ejected out of the pressing rod 16, and the length of the pressing rod 16 can be rotationally adjusted to adjust the relative angle of the rebounder 3 locked by the air support 1.

Preferably, hinge base 6 installs round pin axle 7, and the edge that inserts the end of round pin axle 7 is equipped with the boss, and open at the boss middle part has logical groove, and when inserting round pin axle 7 in hinge base 6, the boss receives the extrusion in bolt hole, to logical groove bending deformation, and the diameter reduces, passes through the bolt hole smoothly, and when the bolt hole was worn out to the boss, deformation resumes, and the boss prevents deviating from of round pin axle, plays the effect of locking.

Preferably, the tail end of the support rod of the air support 1 is provided with a rotating base 4, an inserting cylinder 9 is arranged inside the rotating base 4, and the inserting cylinder 9 is in a cylindrical design with one open end.
