[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Example 1

[0026] See also Figure 1-Figure 5 A turning fixture for a rotary joint housing includes a fixing rod 100, a connecting rod 200 is assembled on the top of the fixing rod 100, and a fastening threaded rod 300 is connected to the top of the connecting rod 200 by setting a thread;

[0027] A clamping assembly 400 is provided at the bottom of the fixed rod 100. The clamping assembly 400 includes a pneumatic chamber 401 that passes through the fixed rod 100 and is fixed to the fixed rod 100. An elastic airbag 402 is fixedly connected to one end of the pneumatic chamber 401, and a clamping rod 403 is slidably connected to the other end of the pneumatic chamber 401. Moving the housing toward the fixed rod 100 squeezes the elastic airbag 402 located there, causing the gas in the elastic airbag 402 to be transferred into the pneumatic chamber 401 fixedly connected thereto. This increases the pressure in the pneumatic chamber 401, driving the clamping rod 403, which is slidably connected to the pneumatic chamber 401, to move. The bottom of the fixed rod 100 is rotatably connected to a torsion spring rod 404. A slot 405 is defined on the outside of the torsion spring rod 404. A clamping rod 403 is positioned within the slot 405. The clamping rod 403 and the slot 405 have the same cross-sectional shape. A clamping rod 406 is fixedly connected to the outside of the torsion spring rod 404. When the clamping rod 403 moves, it is immediately removed from the slot 405 on the torsion spring rod 404, and the torsion spring rod 404 is immediately freed from its restraint. Because the torsion spring rod 404 is in a rotatable connection with the fixed rod 100, the torsion spring rod 404, under its own action, drives the clamping rod 406 fixedly connected to it to rotate, thereby stably clamping the housing. This reduces the number of steps required to clamp the device, making the device easier to use. When the device needs to be reset, the shell is removed by manually rotating the clamping rod 406 in the opposite direction. At this time, the elastic airbag 402 loses the restriction of the shell and expands under its own action. Similarly, it drives the clamping rod 403 to move and reset and move into the clamping slot 405, thereby completing the reset, so that the device can be used next time, thereby improving the usability of the device.

[0028] When in use, the shell is moved toward the fixed rod 100, which can squeeze the elastic airbag 402 located there, so that the gas in the elastic airbag 402 is transmitted to the air pressure chamber 401 fixedly connected thereto due to the squeezing, which increases the pressure in the air pressure chamber 401, driving the clamping rod 403 slidably connected to the air pressure chamber 401 to move, and the clamping rod 403 is immediately moved out of the clamping groove 405 on the torsion spring rod 404, and the torsion spring rod 404 immediately loses its restriction. Because the torsion spring rod 404 and the fixed rod 100 are in a rotational connection state, the torsion spring rod 404 drives the clamping rod 406 fixedly connected thereto to rotate under its own action, thereby stably clamping the shell; when the device needs to be reset, the clamping rod 406 is manually rotated in the opposite direction to remove the shell. At this time, the elastic airbag 402 loses the restriction of the shell and expands under its own action, similarly driving the clamping rod 403 to move and reset and move into the clamping groove 405, thereby completing the reset.

[0029] Example 2

[0030] See also Figure 1-Figure 5 Based on the first embodiment, the clamping rod 406 is provided with a suction assembly 500. The suction assembly 500 includes a hydraulic device 501, which is composed of a hydraulic hose and a hydraulic hard pipe. One end of the hydraulic device 501 is fixedly connected to the fixed rod 100, and the other end is fixedly connected to the clamping rod 406. A rotating rod 502 is fixedly connected to the side of the torsion spring rod 404, and an extrusion plate 503 is fixedly connected to the outer side of the rotating rod 502. When the torsion spring rod 404 rotates to clamp, it drives the rotating rod 502 fixedly connected to the torsion spring rod 404 to rotate, which in turn drives the extrusion plate 503 fixedly connected to it to rotate. One end of the hydraulic device 501 is slidably connected to a curved force-bearing rod 504, which is located on the side of the extrusion plate 503 and is fixed between the curved force-bearing rod 504 and the extrusion plate 503. The other end of the hydraulic device 501 is slidably connected to a suction cup 505. When the extrusion plate 503 rotates, the extrusion plate 503 immediately squeezes the arc-shaped force-bearing rod 504 and moves it, cooperating with the hydraulic device 501 that is slidingly connected to the arc-shaped force-bearing rod 504, so that the pressure in the hydraulic device 501 increases, driving the suction cup 505 that is slidingly connected to the hydraulic device 501 to move, extending the clamping rod 406 and adsorbing the shell, thereby improving the stability of the device during the clamping process.

[0031] During use, based on the first embodiment, when the torsion spring rod 404 rotates to clamp, it can drive the rotating rod 502 fixedly connected to the torsion spring rod 404 to rotate, so that the rotating rod 502 drives the extrusion plate 503 fixedly connected to it to rotate, and the extrusion plate 503 then squeezes the arc-shaped force-bearing rod 504 and moves it, cooperating with the hydraulic device 501 slidingly connected to the arc-shaped force-bearing rod 504, so that the pressure in the hydraulic device 501 increases, driving the suction cup 505 slidingly connected to the hydraulic device 501 to move, extending the clamping rod 406 and adsorbing the shell.

[0032] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
