[0029] Furthermore, an electric push rod 8 is fixedly connected to the top of the fixed pull block 9, and a pressing plate 10 is fixedly connected to the bottom of the electric push rod 8. The side of the pressing plate 10 is slidably connected to the inner wall of the fixed pull block 9, so that the protective clothing can be clamped and fixed.

[0030] Furthermore, a controller 19 is fixedly connected to the side of the sealing cover 2, and the controller 19 is connected to the air pump 1, the electric push rod 28, the motor 17 and the gas detector 20 through a circuit line, which is convenient for the staff to centrally control and can also accurately determine the time when the motor 17 stops operating.

[0034] Through the above technical solution:

[0035] When in use, first start the electric push rod 14 through the controller 19, and then the electric push rod 14 drives the sealing cover 2 to move upward through the fixed plate 3, so that the sealing cover 2 leaves the fixed bottom block 5. At this time, the protective clothing can be placed on the fixed track plate 7, and the edges of the protective clothing are placed inside the 5 fixed pull blocks 9 of the fixed bottom block.

The tooth block 12 passes through the rotating groove 15, so that during the rotation of the tooth block 12, the fixed shaft 14 is squeezed by the rotating groove 15, and gradually moves away from the fixed column 16, thereby driving the connecting plate 11 and the fixed pull block 9 to move outward, so as to pull the protective clothing. Since the bottom of the fixed pull block 9 is in contact with the top of the fixed bottom block 5, only when the protective clothing is torn, the colorless and odorous gas in the sealing cover 2 will enter the protective clothing through the crack, and thus be detected by the gas detector 20. At this time, the motor 17 and the air pump 1 stop working. The time when the gas detector 20 generates an electrical signal to stop the motor 17 can be calculated, and the pulling force on the protective clothing can be calculated, so that the detection data is more accurate.
