The slider 205 is provided with a fixing groove 301. The side end of the fixed frame 202 is slidably connected with a fixing rod 302. The fixing rod 302 and the fixing groove 301 are plugged in. The cross-section of the fixing groove 301 is a trumpet-shaped structure, and the cross-section of the side end of the fixing rod 302 is an arc-shaped structure. The fixing rod 302 is a hexagonal prism-shaped structure as a whole, and the fixing groove 301 is a hexagonal prism-shaped structure as a whole. When the fixing rod 302 and the fixing groove 301 are plugged in, the screen 207 can be positioned.

[0028] As a technical optimization solution of the utility model, the side end of the fixed frame 202 is fixedly connected to a fixed seat 303, and an electric telescopic rod 304 is installed in the fixed seat 303. The output end of the electric telescopic rod 304 is fixedly connected to the fixed rod 302. When the positioning needs to be released, the electric telescopic rod 304 is started in reverse. When the fixed rod 302 and the fixed groove 301 are separated, the screen 207 can slide down automatically.

[0029] As a technical optimization solution of the utility model, the side end of the fixed seat 303 is detachably connected with a cover plate 305, and the inner side of the cover plate 305 is fixedly connected with a fixing plug 306.
