[0002] Watch repair refers to a series of operations to maintain, repair and service a watch to ensure its normal operation and extend its service life. Watch repair mainly includes battery replacement, cleaning and lubrication, parts replacement, time and date correction, waterproofing and movement repair, etc. Watch repair needs to be performed by professional repair personnel or watch repair centers;

[0003] The fixing bracket is one of the commonly used tools in the process of watch repair and maintenance. It is mainly used to clamp and fix the watch case to ensure the stability of the watch during the repair process.

[0004] When a traditional four-legged fixing stand for watch repair is used, in order to ensure the clamping effect on the watch case, it is usually necessary to turn four knobs in sequence to successfully fix the watch case on the fixing stand. The operation method is relatively cumbersome, and the watch case cannot be accurately fixed in the middle of the four-legged fixing stand. Therefore, a four-legged fixing stand for watch repair is proposed. Utility Model Content
