The movement of the plug-in rod 62 drives the moving rod 64 to move inside the cavity 63 and the plug-in rod 62 moves away from the two end blocks 61. The movement of the moving rod 64 drives the connecting spring 66 to stretch, and then the end of the connecting mechanism 1 is plugged between the two end blocks 61. Then the plug-in rod 62 is released, and the connecting spring 66 loses the external force and returns to its original state, driving the moving rod 64 to move into the cavity 63. The movement of the moving rod 64 drives the plug-in rod 62 to move and be plugged into the end blocks 61 and the plug-in groove 67 on the connecting mechanism 1, which facilitates the disassembly and assembly operation of the connecting mechanism 1.

When in use, first move the two docking bearings toward or away from each other along the horizontal screw 1. When the two docking bearings move to the position of the adjusting mechanism 4, stop moving the docking bearings, and then rotate and move the tightening nut along the horizontal screw 1 to make the tightening nut fit the docking bearing, and then connect the adjusting mechanism 4 with the docking ring. Under the action of the mounting ring, the connection operation of the adjusting mechanism 4 and the horizontal screw 1 can be realized, thereby realizing the installation operation of the adjusting mechanism 4 and the tunnel. At this time, the positioning top block is pushed by the spring piece to position the wind tube 5. After positioning, the wind tube 5 will not shake with the wind force, thereby improving the installation stability of the wind tube 5.

[0037] The structure and principle of the adjustment mechanism 4 composed of a mounting frame, a connecting bearing, an adjusting nut, an adjusting screw, a positioning screw and a positioning nut in the utility model have been disclosed in a tunnel ventilation equipment hanging frame disclosed in Chinese patent application No. 202320582879.X, and its working principle is: two groups of symmetrically distributed mounting frames are arranged on the side of the wind duct 5, and an adjusting screw is arranged through the mounting frame, and an adjusting nut is connected to the adjusting screw, and a connecting bearing is installed between the adjusting nut and the mounting frame, and a positioning screw is inserted into the inside of the docking ring in the connecting mechanism 1, and a positioning nut is connected to the outer wall of the positioning screw.

The movement of the plug-in rod 62 drives the moving rod 64 to move inside the cavity 63 and the plug-in rod 62 moves away from the two end blocks 61. The movement of the moving rod 64 drives the connecting spring 66 to stretch, and then the end of the connecting mechanism 1 is plugged between the two end blocks 61. Then the plug-in rod 62 is released, and the connecting spring 66 loses the external force and returns to its original state, driving the moving rod 64 to move into the cavity 63.

The movement of the threaded sleeve 213 drives the cross bar 214 to move inside the opening 215. The movement of the cross bar 214 drives the support rod 24 to move inside the fixing rod 22. When the support rod 24 moves to fit under the wind tube 5, the rotation of the threaded rod 212 is stopped. Under the action of the support rod 24, the wind tube 5 can be supported to ensure the stability of the hoisting of the wind tube 5.
