[0030] The inner wall of the rotating ring 201 and the two sides of the air inlet pipe 202 are provided with a slide groove 207, and the inner wall of the slide groove 207 is slidably connected with a baffle 208. One end of the two baffles 208 extends to the inner wall of the annular pipe 203. Figure 3 As shown, the baffle 208 blocks the annular tube 203, so that the gas input into the inlet pipe 202 can only be output to the outside through the single outlet pipe 204;

[0031] One end of the two baffles 208 also extends to the outside of the rotating ring 201, and the outer walls of the two baffles 208 are fixedly connected to a connecting rod 209. The outer wall of one side baffle 208 is rotatably connected to a screw rod 210, and the other end of the screw rod 210 is fixedly connected to a knob 211. The outer wall surface of the screw rod 210 is threadedly sleeved with the rotating ring 201. Figure 5 As shown, the screw rod 210 is driven to rotate on the side of the rotating ring 201 by the knob 211, thereby driving the baffle 208 to move along the sliding groove 207;

[0032] The restraint mechanism 1 includes a mounting plate 101, the middle part of the surface of the mounting plate 101 is rotatably connected to the rotating ring 201, and the surface of the mounting plate 101 is fixedly connected with abutment tubes 102 on all four sides. The outer wall of each abutment tube 102 is symmetrically fixedly connected to a piston cylinder 104, and the inner wall of the piston cylinder 104 is fixedly connected to an elastic pressure airbag 105. Each abutment tube 102 is symmetrically provided with a card slot 103 on the side away from the piston cylinder 104, and the inner wall of the card slot 103 is movably connected to the card shaft 206.

[0033] The working principle of this utility model:

[0034] When the device is in use, the air pump is connected to the air inlet pipe 202, and the rotating ring 201 is rotated so that the air inlet pipe 202 is aligned with different abutting pipes 102. During the rotation of the rotating ring 201, the arc surface of the clamping shaft 206 is squeezed, thereby compressing the elastic member 205, causing the clamping shaft 206 to shrink into the interior of the rotating ring 201. When the clamping shaft 206 is aligned with other clamping grooves 103, the elastic member 205 pushes the clamping shaft 206 into the interior of the clamping groove 103 and positions it. The air pump inflates the air inlet pipe 202, and the gas enters the interior of the abutting pipe 102 and inflates the elastic pressure airbag 105. After the elastic pressure airbag 105 expands, it pushes the side ear 107 by pushing the movable rod 106, and then the restraining ring 108 drives the steel rope to move and increases the preload force.

[0035] When it is necessary to adjust the pre-tightening force of all steel ropes at the same time, rotate the knob 211, and the screw rod 210 drives the baffle 208 to move along the slide groove 207, so that the baffle 208 cancels the blockage of the annular tube 203. At this time, when air is inflated into the air inlet pipe 202, all elastic pressure airbags 105 can be expanded at the same time, thereby increasing the pre-tightening force of all steel ropes.

[0036] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
