[0030] By adopting the above solution, the control mechanism 7 is provided to control the fixing mechanism 5 , making it convenient for the user to use the fixing mechanism 5 .

[0031] refer to Figure 3 , one side of the guardrail 2 close to the inner wall of the positioning groove 3 contacts the inner wall of the positioning groove 3.

[0032] By adopting the above solution, the positioning groove 3 is provided to position the guardrail 2 , making it convenient for the user to use the guardrail 2 .

[0033] refer to Figure 3 A first through hole 8 for use with the fixing block 503 is opened on one side of the inner cavity of the movable groove 4 close to the fixed groove 6, and a second through hole 9 for use with the control rod 702 is opened on the right side of the right movable groove 4.
