[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit its scope.

[0027] The present invention will now be further described with reference to the accompanying drawings.

[0028] Example 1

[0029] Combined with appendix Figure 1-3 The lower housing 1 has an opening at one end, and clamping rods 3 are symmetrically hinged in the opening. One end of the clamping rods 3 protrudes from the lower housing 1, and the other end is located inside the lower housing 1. The clamping rods 3 are bent relative to each other.

[0030] The clamping rod 3 inside the opening is provided with guide blocks 4 symmetrically arranged on the left and right sides. A transmission rod 5 is slidably connected between the guide blocks 4. One end of the transmission rod 5 is exposed outside the lower housing 1. A transmission block 6 is provided on the side of the end of the transmission rod 5 located inside the lower housing 1. The side of the transmission block 6 facing the clamping rod 3 is inclined. The side of the transmission block 6 facing the clamping rod 3 is in contact with one end of the clamping rod 3.

[0031] The lower housing 1 is equipped with a cylinder 7. The piston rod of the cylinder 7 is connected to the transmission rod 5. The clamping rod 3 is located at one end inside the lower housing 1, and its opposite side is connected to the side of the lower housing 1 by a spring 8.

[0032] During operation, the piston rod of cylinder 7 extends, driving the transmission rod 5 to move out of the lower housing 1. As the transmission rod 5 moves, it drives the clamping rod 3 to move relative to it via the transmission block 6. Together, the clamping rod 3 and the transmission rod 5 provide a stable, self-centering clamping effect on the generator rear cover. When the generator rear cover is released, the piston rod of cylinder 7 retracts, and the clamping rod 3, under the action of spring 8, moves away from the end of the lower housing 1, returning to its initial position.

[0033] Combined with appendix Figure 1-3 The clamping rod 3 is rotatably connected to rollers at both ends, and the transmission rod 5 is also rotatably connected to rollers at one end exposed in the lower housing 1.

[0034] When the transmission rod 5 moves, the rollers on the clamping rod 3 roll on the transmission block 6 to ensure smooth transmission. The rollers exposed on the lower housing 1 clamp the generator rear cover.

[0035] Combined with appendix Figure 2 The guide block 4 has a limiting block 11 on one side opposite to it, and the transmission rod 5 has a limiting groove 12 on its side. The limiting block 11 and the limiting groove 12 are slidably connected.

[0036] During the movement of the transmission rod 5, the limiting block 11 on the guide block 4 slides in the limiting groove 12 on the side of the transmission rod 5, providing good guidance for the movement direction of the transmission rod 5.

[0037] Example 2

[0038] Combined with appendix Figure 1 and 4 The inner surface of the side of the lower housing 1 is provided with a connecting post 9, the connecting post 9 is provided with a threaded hole, the cover plate 2 is provided with a groove, the groove is provided with a bolt 10, and the bolt 10 passes through the groove and is threadedly connected to the threaded hole on the connecting post 9.

[0039] The lower housing 1 has a positioning groove 13 on its inner surface, and the cylinder 7 is engaged with the positioning groove 13.

[0040] A pressing pad 14 is provided on the inner surface of the cover plate 2 at the position corresponding to the cylinder 7.

[0041] Based on Embodiment 1, the cover plate 2 is connected to the connecting column 9 on the lower housing 1 by bolts, which facilitates the disassembly and assembly of the housing and thus facilitates the maintenance of the internal structure.

[0042] The positioning groove 13 and the pressing pad 14 work together to fix the position of the cylinder 7.

[0043] The utility model and its embodiments have been described, but this description is not restrictive. The figures shown are only one embodiment of the utility model, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the spirit of the utility model, such design should fall within the protection scope of the utility model.
