[0014] 1. The utility model is provided with a clamping mechanism. When the adhesive strip is bonded between two plastic plates, one hand holds the handle and the other hand rotates the threaded rod to make the threaded rod leave the through hole. The restoring force of the spring can make the pressing plate drive the clamping column to descend. The hand continues to hold the handle to prevent the clamping column from descending too quickly. When the clamping column contacts the adhesive strip, the handle is released. The downward pressure of the clamping column compresses the adhesive strip to enhance the bonding effect. Compared with the comparative documents, the clamping method of the present application is more convenient, simple in steps, and more labor-saving.

[0015] 2. The utility model sets a clamping mechanism and rotates the screw rod to move the two sliders closer to each other, thereby driving the anti-deviation plates closer to each other and clamping the two plastic plates at the same time. Compared with the spring clamping method, it is more stable and by adjusting the distance between the two anti-deviation plates, plastic plates of different widths can be clamped. The telescopic distance of the spring in the comparative document is smaller, and the clamping range of the present application is larger. BRIEF DESCRIPTION OF THE DRAWINGS
