The power device is specifically a cylinder 6. The cylinder bodies of the two cylinders 6 are respectively fixed on the left and right side walls of the protective box 1 by bolts. The piston rod of the cylinder 6 extends downward, and the piston rod of the cylinder 6 is fixedly connected to the movable plate 5 by bolts.

[0022] A sealing plug 7 is installed at the bottom of the movable plate 5 for sealing the mouth of the glove 23 and pressing it against the glove mounting seat 4. The sealing plug 7 is in the shape of an inverted truncated cone that matches the inner wall of the glove mounting seat 4. The sealing plug 7 corresponds to the glove mounting seat 4 one by one and is located directly above the corresponding glove mounting seat 4. The sealing plug 7 is provided with an air inlet 8 for inflating the glove 23. One end of the air inlet 8 is connected to the bottom of the sealing plug 7 and the other end is connected to one side of the upper end of the sealing plug 7. An air inlet pipe 9 is fixedly installed on the inner side of the top wall of the protective box 1. One end of the air inlet pipe 9 is connected to an air pump 10 through a pipeline. The air inlet pipe 9 is provided with an air inlet branch pipe 11 that corresponds to the sealing plug 7 one by one. Figure 4 As shown, a hose connector 12 is screwed into one end of the air inlet 8 away from the bottom of the sealing plug 7, and the inflation branch 11 is connected to the corresponding hose connector 12 through a hose 13, and an electric valve 24 is installed at the inflation branch 11. An air pressure sensor 14 for measuring the air pressure in the glove 23 is also fixedly installed at the bottom of the sealing plug 7.
