The traction bar 7 can clamp one end of the PE film and then slide through the second traction groove 204 and the first traction groove 101 to drive one end of the PE film to pass through the interior of the equipment and pass through the lifting and stretching roller 5 and the positioning stretching roller 4. In this way, when the lifting and stretching roller 5 moves, the PE film can be placed between the lifting and stretching roller 5 and the positioning stretching roller 4 and stretched by the positioning stretching roller 4 and the lifting and stretching roller 5.

[0026] The top of the shell 2 is provided with a top plate 3, and a motor 301 is installed inside the top plate 3. The bottom of the motor 301 is connected to a first rotating shaft 304, and the side of the first rotating shaft 304 is connected to a transmission belt 302. The end of the transmission belt 302 away from the first rotating shaft 304 is connected to a second transmission shaft 305 with a diameter smaller than the first rotating shaft 304. A group of screw rods 303 are fixed to the bottoms of the second transmission shaft 305 and the first rotating shaft 304, and the screw rods 303 are set between the limit plate 202 and the positioning stretching roller 4. When the motor 301 is started, the first rotating shaft 304 can be driven to rotate, and then the first rotating shaft 304 can be driven to rotate. A group of screw rods 303 below the rotating shaft 304 rotates, and another group of screw rods 303 can drive the second transmission shaft 305 to rotate through the transmission belt 302, so that the position of the adjustment plate 502 on the two groups of screw rods 303 can be adjusted. The clothes moth of the base 1 is fixed with a back plate 6, and the back plate 6 is fixedly connected to the shell 2. Baffles 201 are fixed at both ends of the shell 2, and support plates 102 are also fixed at both ends of the base 1 close to the baffle 201.
