Description

TECHNICAL FIELD

[0001] The utility model relates to a watch processing technical field, especially a watch pointer mounting device. BACKGROUND

[0002] Quartz watches are electronic watches that use a battery as a power source and a quartz crystal oscillator as a time reference. They are popular among consumers for their accurate time display, low maintenance requirements, and wide price range. They usually contain an integrated circuit to control the movement of the hands, and some models also have additional functions such as date display, alarm, timer, etc. Quartz watches are widely popular worldwide for their durability, accuracy, and ease of use.

[0003] The hands of a watch (hereinafter referred to as watch hands) are the key components for displaying time, usually including hour hand, minute hand and second hand. They are installed on the dial and rotate around the watch shaft to indicate the current time. In related technology, watch hand installation is very difficult, mainly because the watch hand is small and precise, requiring high installation accuracy. At the same time, the internal space of the watch is narrow, and the operation space is limited, making it difficult to accurately align and fix the watch hand during installation.

[0004] The watch hand is installed on the watch shaft in an eccentric manner, with one end longer and the other end shorter. This results in the longer end sagging under the influence of gravity during installation, and the watch hand is not horizontal during installation. This causes the inner wall of the needle hole of the watch hand to form an angle with the outer wall of the watch shaft. Since the fitting tolerance between the needle hole and the watch shaft is high, pressing the watch hand and the watch shaft at this time will cause the needle hole or the watch shaft to deform under pressure. SUMMARY
