The outside of the trapezoidal column 7 is fixedly connected to the right inner wall of the shell 1, and the front and rear sides of the trapezoidal column 7 are fixedly connected with limiting rods 8, which are fixedly connected to the front and rear sides of the trapezoidal column 7 to limit the movement range of other components. A rotating assembly is provided at the right end of the shell 1, and the rotating assembly includes a sleeve 9. The inside of the sleeve 9 is slidably connected to the right end of the shell 1, so that the shell 1 can be quickly disassembled from the inside of the sleeve 9.

[0023] Reference Figure 3 - Figure 5 Two special-shaped cavities 10 are provided inside the sleeve 9 to limit the movement trajectory of the limit rod 8. A plurality of strong springs 11 are fixedly connected to the right side of the inner wall of the sleeve 9 at the far end. The right sides of the plurality of strong springs 11 are fixedly connected to the right side of the inner wall of the sleeve 9. The two sides of the strong springs 11 are fixed so that the strong springs 11 can be evenly stressed. Two arc plates 12 are slidably connected to the inner wall of the rotating assembly. The left sides of the plurality of strong springs 11 are respectively fixedly connected to the right sides of the two arc plates 12. The outer sides of the arc plates 12 are slidably connected to the inside of the special-shaped cavity 10. The outer sides of the two arc plates 12 are slidably connected to the inner wall of the sleeve 9. The arc plates 12 can move stably through the restrictions of the sleeve 9 and the special-shaped cavity 10. A spline groove 13 is provided inside the dovetail column 4

[0024] Working principle: when the shell 1 needs to be removed separately, by holding the shell 1, pressure is applied to the inside of the sleeve 9, and then the limit rod 8 is driven to slide on the inner wall of the sleeve 9 and push the arc plate 12, and then the arc plate 12 will squeeze the strong spring 11, so that the strong spring 11 can store elastic potential energy, and after the sleeve 9 slides to a suitable position, the special-shaped cavity 10 opened by processing makes the inside of the sleeve 9 form two hook-shaped structural tendencies, and then the shell 1 is rotated ninety degrees, at this time the shell 1 can be taken out, and when installing, the shell 1 needs to push the limit rod 8 to slide in the special-shaped cavity 10 opened in the sleeve 9 Inside, and push the arc plate 12 again to compress the strong spring 11. After sliding to the appropriate position, turn ninety degrees again to release the pressure on the shell 1. At this time, the arc plate 12 will be pushed by the elastic force provided by the strong spring 11, pushing the arc plate 12 against the limit rod 8 to complete the installation. The spline groove 13 opened by the dovetail column 4 cooperates with the spline shaft, and the worm also cooperates with the thrust part to prevent the generation or transmission of axial thrust. This design is mainly used to ensure that the worm shaft remains stable during operation and does not generate unnecessary friction or vibration due to axial thrust, thereby improving the reliability and performance of the system.
