detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Figures 1 to 3. In an embodiment of the present invention, a keyboard for computer teaching includes a base 1. Suction cups 17 are connected to both sides of the lower end of the base 1 for fixing the base 1 on the desktop. The upper end of the base 1 The two sides are connected with annular chute 15, and the middle part of annular chute 15 is connected with ball 16, and ball 16 can roll in the annular chute 15, and the left side of the upper end of the base 1 is connected with telescopic sleeve 4, and the inner telescopic spring 3 of telescopic sleeve 4 The lower end of the telescopic spring 3 is connected with the base 1 for fixing the telescopic spring 3, the upper end of the telescopic spring 3 is connected with the telescopic post 6, and the left end of the telescopic post 6 is connected with the telescopic pressure plate 5 for adjusting the up and down movement of the telescopic post 6, so The upper end of the annular chute 15 is connected with a support plate 5, and both sides of the support plate 5 are evenly provided with telescopic holes 14, and the telescopic holes 14 are matched with the telescopic column 6, thereby realizing the fixing of the telescopic column 6, the support plate 2 The upper end is connected with a fixed plate 13, and the middle part of the upper end of the fixed plate 13 is provided with a groove for placing the adjusting rod 12. When the keyboard is not in use, the adjusting rod 12 is placed in the groove to avoid mutual interference with the keyboard body 9. The fixed plate 13 The upper end is provided with slide rail 8, and the middle part of slide rail 8 is connected with slide ball 7, and described slide ball 7 can move left and right along slide rail 8, and can realize turning over at the two ends of slide rail 8, and the upper end of described fixed plate 13 is right The side is connected with an adjustment rod 12, and the adjustment rod 12 is connected with a support plate 13 through a rotating seat, so that the adjustment rod 12 can rotate left and right, and then the up and down angle of the keyboard body 9 can be adjusted.
