[0027] Clamping assembly 5 includes mounting frame 51, the top of mounting frame 51 is slidably penetrated by two sliding rods 52, the outer wall of two sliding rods 52 is sleeved with spring 53, the bottom of two sliding rods 52 is fixedly installed with plug 54, plug 54 is under the action of spring 53 and is forced into the inside of recess 4, the top of two sliding rods 52 is fixedly installed with pull plate 55, and pull plate 55 can drive sliding rod 52 and plug 54 to move, the outer wall one side of mounting frame 51 is fixedly installed with L-shaped plate 56, the outer wall one side of L-shaped plate 56 is slidably penetrated by moving plate 57, and moving plate 57 can slide on L-shaped plate 56.

[0028] The outer wall one end of plug 54 close to the opening of recess 4 is provided with bevel, when the one side of the bevel of plug 54 is extruded, plug 54 will move, the top of moving plate 57 is fixedly installed with two limiting plates 58, limiting plate 58 can prevent moving plate 57 from falling on L-shaped plate 56, and moving plate 57 can move within a certain range, so that moving plate 57 can move below pull plate 55 or away from the below of pull plate 55, and the two limiting plates 58 are arranged on the two outer walls of L-shaped plate 56.

[0029] The outer wall one end of two springs 53 is fixedly connected with the inner wall top of mounting frame 51, and the outer wall other end of two springs 53 is fixedly connected with the top of plug 54.

[0030] Figures 1-6 The second embodiment is shown, and the main difference from the first embodiment is that the bottom end of the plug 54 slides through the inner wall of the groove 4, and the top end of the convex block 3 is provided with a clamping groove 6 matched with the plug 54.

[0031] The convex block 3 is matched with the groove 4, the bottom end of the first template 1 is fixedly installed with a connecting frame 8, and the bottom end of the second template 2 is fixedly installed with a connecting plug plate 7.

[0032] The outer wall of the connecting plug plate 7 is matched with the inner wall of the connecting frame 8, so that the connecting plug plate 7 can be inserted into the inside of the connecting frame 8, thereby enhancing the stability of the connection between the templates, and the bottom end of the first template 1 and the second template 2 is fixedly installed with a bottom reinforcing plate 9.
