The left and right side walls of the connecting plate 120 are provided with mounting grooves 125, and the left and right sides of the top of the connecting plate 120 are screwed with positioning bolts 126. The bottom end of the positioning bolt 126 penetrates the connecting plate 120 and extends to the inner cavity of the mounting groove 125. The inner cavity of the mounting groove 125 is plugged with an L-shaped plate 127, and the positioning bolt 126 is screwed with the positioning bolt 126. The bottom end of the left side press platform 131 is tightly fitted with the top of the L-shaped plate 127, the bottom of the L-shaped plate 127 is fixedly connected with a rubber plate 128, the upper side of the right side wall of the left side press platform 131 is fixedly connected with an extension plate 132, the top of the right side press platform 131 is provided with an extension groove 133, the extension plate 132 is slidably connected to the inner cavity of the extension groove 133, the interior of the left side press platform 131 is screwed with a first screw rod 140, the two ends of the first screw rod 140 pass through the left side press platform 131 and extend to the left and right sides of the left side press platform 131, the left end of the first screw rod 140 is rotatably connected to the right side of the left support plate 110 On the lower side of the side wall, a second screw 150 is screwed inside the right press platform 131, both ends of the second screw 150 pass through the right press platform 131 and extend to the left and right sides of the right press platform 131, the left end of the second screw 150 is fixedly connected to the right end of the first screw 140, the right end of the second screw 150 passes through the right support plate 110 and extends to the right side of the right support plate 110, and the right end of the second screw 150 is fixedly connected to a handle 151, the thread directions of the first screw 140 and the second screw 150 are opposite, and a universal wheel 160 is fixedly connected to the top of the base 100.
