[0036] The second connecting grooves 421 are symmetrically provided at both ends of the second sliding member 42; a second elastic member 43 is provided in the second connecting groove 421; one end of the second elastic member 43 abuts against the bottom surface of the second connecting groove 421; the other end of the second elastic member 43 abuts against the side wall of the second mounting groove 13; When the No. 1 connecting structure 411 slides toward the side close to the center of the connecting seat 1, the No. 2 sliding member 42 moves toward the side of the center of the connecting seat 1 under the action of the elastic force of the No. 2 elastic member 43, so that the No. 3 connecting layer 44 is detached from the No. 1 sliding structure 21, making it convenient for the No. 1 sliding structure 21 to slide.

[0037] A third connecting groove is provided on the side wall of the first sliding structure 21 away from the second sliding member 42 ; a rubber block 213 is fixedly connected in the third connecting groove.

[0038] After adjusting the position of one support member 2, the friction between the rubber block 213 and the side wall of the No. 1 sliding groove 12 increases the stability of the No. 1 sliding structure 21, increases the firmness of the support member 2, and when adjusting the positions of other support members 2, reduces the probability of the adjusted support member 2 moving, and increases the stability of the position of the adjusted support member 2.

[0039] A third protruding structure 211 is disposed at the lower portion of the side wall of the first sliding structure 21 ; the third protruding structure 211 is disposed close to the second sliding member 42 .

[0040] When the third connecting layer 44 contacts the first sliding structure 21 , the third protruding structure 211 contacts the third connecting layer 44 , thereby increasing the friction between the third connecting layer 44 and the first sliding structure 21 , increasing the sliding resistance of the first sliding structure 21 , increasing the stability of the first sliding structure 21 , and increasing the stability of the support 2 .

[0041] No. 1 protrusion structures 4121 are evenly spaced on the side wall of the No. 2 sliding structure 412; a No. 1 slope structure 4122 is provided on one side of each No. 1 protrusion structure 4121; No. 2 groove structures 422 are evenly spaced on the side wall of the No. 2 sliding member 42; a No. 2 slope structure 423 is provided on one side of each No. 2 groove structure 422.

[0042] There are multiple No. 1 protrusion structures 4121 and No. 2 groove structures 422, and the corresponding No. 1 slope structures 4122 and No. 2 slope structures 423 are in contact with each other, so that the No. 2 sliding member 42 is evenly stressed, and the pressure between each No. 3 connecting layer 44 and the corresponding No. 1 sliding structure 21 is equal, preventing the pressure between a No. 3 connecting layer 44 and the corresponding No. 1 sliding structure 21 from being too small, thereby reducing the stability of the position of the No. 1 sliding structure 21, increasing the stability of the No. 1 sliding structure 21, and increasing the stability of the support member 2.

[0043] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation modes, which are merely illustrative rather than restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are within the protection of the present invention.
