[0050] The screen body 1 of the present invention is detachably connected to the fixing plate 2, which facilitates the replacement of the screen body 1. The locking and fixing of the screen body 1 is achieved by using the locking mechanism 5, which is more convenient and has a better fixing effect. The driving motor 9 drives the connecting rod 11 to rotate through the belt 13, and the connecting rod 11 drives the locking nut 8 to rotate through the first gear 14 and the second gear 15, and the locking nut 8 drives the locking rod 7 to move, and finally the locking head 16 is clamped in the locking groove 17 to fix the screen body 1. The transmission wheel and the connecting rod 11 are used to realize the translational clamping of four locking heads 16 driven by a driving motor 9 at the same time, which can ensure the synchronous locking of the locking head 16 and improve the locking effect of the locking mechanism 5. The transmission structure of the locking mechanism 5 is stable and reliable, with a long service life and a good locking effect.

[0051] The present invention adopts four steps to install the screen body 1, namely, a. installation of the support seat 3; b. installation of the fixing plate 2; c. debugging of the bracket structure; and d. installation of the screen body 1. The steps are simple, the installation effect is good, the installation efficiency is high, and the installation time is saved. At the same time, during the locking process of the screen body 1, the movement of the clamping plate 18 is used to trigger the locking, which is convenient and has a good locking effect. The installation of the screen body 1 is simple and convenient, and the replacement of the screen body 1 is also simple and convenient, saving time, eliminating cumbersome steps, and having a good installation effect.

[0052] The above are only specific embodiments of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent replacements or modifications made based on the present invention to solve basically the same technical problems and achieve basically the same technical effects are all included in the protection scope of the present invention.
