During the rotation of the hollow shaft 10, each toggle column 15 is driven to move in the corresponding U-shaped plate 12. The U-shaped plate 12 can prevent the toggle column 15 from detaching, thereby moving the piston plate 21 in the air filling box 18 through the sliding rod 22, and the gas stored in the air filling box 18 can be input into the rectangular high-temperature resistant airbag 13 through the air supply pipe 19, so that each part of the rectangular high-temperature resistant airbag 13 is inflated at the same time.

[0038] Working principle: When the sealing furnace cover 2 is closed to seal the tempering furnace body 1, during this process, the hemispherical end of the pressing column 28 can contact the surface of the tempering furnace body 1. As the sealing furnace cover 2 continues to move, the pressing column 28 can apply force to the piston plate 27 in the inflation box 24, so that the piston plate 27 presses the connecting spring 26 to move, so that the gas stored in the inflation box 24 can be input out through the gas transmission one-way pipe 23, and the gas discharged from the gas transmission one-way pipe 23 will enter the rectangular gas collecting cavity 29, and finally be ejected through a plurality of jet holes 30.

When the rotating shaft 31 rotates, it will drive the cleaning brush 34 to clean the surface of the threaded column 3, and when the cleaning brush 34 contacts the surface of the threaded column 3, under the action of the elastic force of the connecting spring three 33, the cleaning brush 34 will tightly adhere to the surface of the threaded column 3, so that the solid impurity particles stuck in the thread groove on the surface of the threaded column 3 can be cleaned off, and the solid particles stuck on the surface of the threaded column 3 are prevented from affecting the screwing. At the same time, when the cleaning brush 34 is separated from the threaded column 3, the connecting spring three 33 will make the cleaning brush 34 shake, so as to shake off the garbage impurity particles attached to the cleaning brush 34 when cleaning, thereby ensuring the cleanliness of the cleaning brush 34, and there is no need to manually clean the cleaning brush 34.

[0041] Working principle: When the rotating mechanism rotates the hollow shaft 10, the shaft 31 on the external mounting plate 32 can be rotated through the transmission of the pulley 1 35, the belt 36 and the pulley 2 38.

At the same time, when the cleaning brush 34 is separated from the threaded column 3, the connecting spring 3 33 will make the cleaning brush 34 shake, so as to shake off the garbage impurity particles attached to the cleaning brush 34 when cleaning, so as to ensure the cleanliness of the cleaning brush 34, and there is no need to manually clean the cleaning brush 34.
