[0003] The quartz clock movement, as the core component of the quartz clock, the optimization degree of its internal structure directly determines the performance and cost-effectiveness of the whole machine. However, the traditional movement design is often based on empiricism and conservative strategy, resulting in a large number of surplus empty spaces inside. These spaces have not been effectively utilized, which not only increases the material cost, but also limits the miniaturization and lightweight development of the movement.

[0004] The waste of structural resources mainly reflects in the following aspects: first, the movement layout is unreasonable, the gap between the components is too large, and the compact and efficient arrangement cannot be achieved; second, unnecessary complex structure exists in the movement, which increases the processing difficulty and cost; third, due to the redundancy of design, the overall weight of the movement is relatively large, which is not conducive to energy saving and environmental protection.

[0005] Taking the suspension position design of the movement as an example, the traditional method often sets the suspension part on the front cover body of the movement. The original intention of this design may be to facilitate installation or maintenance, but objectively it leads to the increase of the overall size of the movement, especially exceeding the effective range of the movement cover plate, which further affects the layout flexibility of the movement in the clock body, increases the overall volume of the clock body, and is not conducive to the effective use of space. SUMMARY

[0011] The anti-disengagement part comprises an anti-disengagement plate arranged on the inner side of the rear cover, which extends into the inner side of the front cover and abuts against the lower end of the upper side wall of the front cover.

[0012] The anti-disengagement part comprises a positioning column and a positioning hole or a positioning groove arranged on the front cover and the rear cover, the positioning column is fixedly arranged on one of the cover plates of the front cover and the rear cover, and the positioning hole or the positioning groove is fixedly arranged on the other cover plate; the positioning column is assembled in the positioning hole or the positioning groove, and the positioning column matches the positioning hole or the positioning groove.

[0013] The hanging part is a groove arranged on the outer side of the rear cover.

[0014] The hanging part is a through hole arranged in the blank area of the rear cover.

[0015] The positioning column and the positioning groove are arranged on the rear side of the hanging part, so that the total length of the matched positioning column and the positioning groove is less than the distance between the inner sides of the front cover and the rear cover.

[0016] The beneficial effects of the above technical solutions are:

[0017] 1. The utility model innovatively proposes a new scheme of arranging a hanging position on the rear cover of the movement. This reform not only greatly optimizes the internal structure layout of the movement, but also enables the movement to significantly reduce the occupied space in the clock body while maintaining the original functional integrity, thereby improving the design freedom of the clock body and providing the possibility of designing a more compact and exquisite clock product. In addition, since the hanging position is arranged on the rear cover, the hanging position will not exceed the cover of the movement and be hidden, so the logistics packaging box of the movement can also be correspondingly reduced, reducing the consumption of packaging materials and meeting the urgent needs of the current society for green and environmentally friendly production.

[0018] 2. The implementation of this utility model is not only a significant breakthrough in traditional design concepts, but also a powerful demonstration of the quartz clock industry's technological innovation capabilities. It will not only promote the miniaturization and lightweighting of products, enhancing market competitiveness, but also hopefully lead the industry's transition to a more efficient and environmentally friendly production model. With the gradual promotion of this innovative technology, we have reason to believe that future quartz clock products will better align with modern home aesthetics, achieving a perfect fusion of functionality and aesthetics, and providing consumers with a higher quality of life experience. At the same time, this will also encourage more companies to increase R&D investment, jointly propelling my country's quartz clock manufacturing industry to a higher level of development.
