The fixing device 8 includes a support plate 81, a rotating rod 82, a fixed sleeve 83, a movable rod 84, a limiting block 85, a locking block 86, a locking groove 87, a fixing rod 88, a sliding groove 89, and an adjusting mechanism 810. The support plate 81 is fixed inside the movable block 3. The rotating rod 82 is rotatably connected to the right end of the support plate 81 via a bearing, and the rotating rod 82 passes through the interior of the movable block 3. The fixed sleeve 83 is fixed to the outside of the rotating rod 82, the movable rod 84 is fixed to the outside of the fixed sleeve 83, the limiting block 85 is fixed to the right end of the support plate 81, and the locking block 86 is fixed to the outside of the fixed sleeve 83. Block 86 penetrates the interior of movable block 3 and is located inside slot 87, which is located inside connecting block 5. Fixing rod 88 is fixed to the right end of block 86, and its outer side is located inside sliding groove 89, which is located inside movable rod 84. Adjustment mechanism 810 is located at the right end of movable block 3. Limiting block 85, block 86, and slot 87 are arranged horizontally. This arrangement allows block 86 to extend into slot 87 during movement through the cooperation of limiting block 85. The inner part has a notch and fits against the outer side of the locking block 86. This setting restricts the movement trajectory of the locking block 86 by the limiting block 85.

There are four sets of movable rod 84, limiting block 85, locking block 86, locking groove 87, fixing rod 88 and slide groove 89, which are equally distributed inside the movable block 3. This setting improves the fixing effect between the movable block 3 and the connecting block 5.

[0025] Please see Figure 5 This utility model provides a rubber torsion shaft technical solution: a rubber torsion shaft, the adjusting mechanism 810 includes a protective shell 8101, a worm gear 8102, a worm 8103 and a handle 8104. The protective shell 8101 is fixed to the right end of the movable block 3, the worm gear 8102 is fixed to the outside of the rotating rod 82, the worm 8103 meshes with the worm gear 8102, and one end of the worm 8103 is rotatably connected to the inside of the protective shell 8101 through a bearing seat. The handle 8104 penetrates the inside of the protective shell 8101, and the rear end of the handle 8104 is fixedly connected to the worm 8103. The outer side of the handle 8104 is provided with anti-slip texture, which makes the rotation of the handle 8104 more stable.

[0026] The working principle is as follows:

[0027] First, when the rubber rod 4 inside the rubber torque shaft is damaged during use, it needs to be replaced.

[0028] Second, rotate the handle 8104 to drive the worm 8103 to rotate. When the worm 8103 rotates, it drives the worm wheel 8102 to rotate. When the worm wheel 8102 rotates, it drives the rotating rod 82 to rotate. When the rotating rod 82 rotates, it drives the fixed sleeve 83 to rotate.

[0029] Third, when the fixed sleeve 83 rotates, it drives the movable rod 84 to rotate. When the movable rod 84 rotates, it drives the fixed rod 88 to rotate, causing the fixed rod 88 to move along the slide groove 89. When the fixed rod 88 moves, it drives the locking block 86 to move. The locking block 86 moves along the inside of the limiting block 85, causing the locking block 86 to move out of the slot 87.

[0030] Fourth, when the locking block 86 is removed from the slot 87, the fixing effect between the movable block 3 and the connecting block 5 can be canceled, and the connecting block 5 can be removed from the movable block 3. Then the rubber rod 4 can be replaced. After the replacement is completed, the connecting block 5 is inserted along the movable block 3, and the handle 8104 is rotated in the opposite direction to make the locking block 86 extend into the slot 87 to complete the fixing between the movable block 3 and the connecting block 5, and then it can be used again.

The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0032] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
