The positioning member 5 includes a shell 51 rotatably connected to the left end of the upper side of the lifting plate 4. A second motor 52 is provided at the bottom of the shell 51. A second screw 53 driven by the second motor 52 is rotatably connected to the middle part of the shell 51. The second screw 53 is threadedly connected to a traction plate 54 slidably connected to the inner side of the shell 51. Four groups of traction arms 55 are rotatably connected to the upper edge of the traction plate 54. The oblique upper end of the traction arm 55 is rotatably connected to a clamping block 56 slidably connected to the shell 51.
