[0025] The inner wall of the fixed box 7 is slidably connected with a trapezoidal slider 8, so that the trapezoidal slider 8 can slide horizontally, and the inner wall of the trapezoidal slider 8 is rotatably connected with a circular plate 9, which is used to limit the circular plate 9 to prevent the circular plate 9 from falling off. The external thread of the threaded rod 10 is connected to the inner wall of the rear end of the fixed box 7. The threaded rod 10 is restricted by the fixed box 7 so that the threaded rod 10 can move forward and backward after rotation. The rear side of the circular plate 9 is fixedly connected with the threaded rod 10, and the circular plate 9 is driven to rotate together by the force of the threaded rod 10. The front end of the threaded rod 10 is rotatably connected to the inner wall of the rear end of the trapezoidal slider 8, and the rear side of the threaded rod 10 is fixedly connected with a turning handle 11. The threaded rod 10 is driven to rotate by holding the turning handle 11 and applying a rotating force. The left and right ends of the rear side of the inner wall of the control housing 1 are fixedly connected with special-shaped blocks 12 to provide supporting force for the special-shaped blocks 12, and the inner walls of the two special-shaped blocks 12 are fixedly connected with telescopic components on the far side.

[0026] Reference Figure 1 , Figure 4 and Figure 5 , the two telescopic components each include a limit rod 13, the inner walls of the two special-shaped blocks 12 have a side far from each other fixedly connected to the side far from each other of the two limit rods 13, providing support force for the limit rod 13, the outer sleeve of the limit rod 13 is provided with a spring 14, the two springs 14 have a side far from each other fixedly connected to the inner walls of the two special-shaped blocks 12, and the springs 14 can be uniformly stressed by fixing both sides of the spring 14 and restricting the inside, and the outer sliding connection of the telescopic component is provided with a sliding plate 15, the rear sides of the two sliding plates 15 are respectively slidably connected to the left and right ends of the rear side of the inner wall of the control housing 1, and the left and right sides of the trapezoidal slider 8 are respectively in contact with the adjacent side of the two sliding plates 15, and the sliding plate 15 can be pushed to move after the trapezoidal slider 8 is forced to slide;

[0027] The outer part of the limit rod 13 is slidably connected to the inner wall of the sliding plate 15. The limit rod 13 limits the sliding plate 15 so that the sliding plate 15 can slide horizontally. The adjacent sides of the two springs 14 are respectively fixedly connected to the distant sides of the two sliding plates 15.

The outer side of the limit plate 19 is slidably connected to the inner wall of the hook block 17. The limit plate 19 can slide horizontally due to the restriction of the hook block 17. The far sides of multiple limit plates 19 are fixedly connected to the rubber plates 20. The limit plates 19 are pushed to slide after being stressed. The outer side of the rubber plate 20 is slidably connected to the inner wall of the hook block 17. The rubber plate 20 can slide horizontally due to the restriction of the hook block 17.

[0029] Working principle: When we use the gas bearing Stirling refrigerator control device, we separate the connected cables and wrap them around the outside of the hook-shaped blocks 17 in pairs. In order to adapt to the length of the cables, we hold the turning handle 11 and apply a rotating force to drive the threaded rod 10 to rotate on the inner wall of the fixed box 7 for limiting, so that the threaded rod 10 can move on the inner wall of the fixed box 7, and then drive the circular plate 9 to rotate on the inner wall of the trapezoidal slider 8, so that the trapezoidal slider 8 is pushed forward by the force pushed by the threaded rod 10, and the inclined push on both sides of the trapezoidal slider 8 pushes the two inclined sliding plates 15 to move in opposite directions on the special-shaped block 1 2, and at the same time, the sliding plate 15 slides outside the limiting rod 13 and pushes the spring 14, so that the spring 14 can store elastic potential energy, and then give the sliding plate 15 a reset force, and the two sliding plates 15 move in a special shape to push the connecting plate 16 to slide respectively, and then push the hook block 17 to slide to adapt to the excess cable length, and then the cable is wound around the outside of the hook block 17 in pairs, and at the same time, the cable will squeeze the rubber sheet 20, so that the rubber sheet 20 pushes the limiting plate 19 to slide outside the hook block 17 and squeezes the spring 2 18 after being subjected to force, thereby giving the rubber sheet 20 a force in the opposite direction, and then improving the loosening effect.
