[0002] The flashlight lamp holder positioning and installation mechanism usually involves multiple components to ensure the correct position and firm connection of the lamp holder. The existing flashlight barrels are generally divided into two types: separated head and body and integrated barrel. Most of them use a threaded connection to rotate and tighten the barrel and the head cover to ensure the firm installation of the internal lamp holder assembly. On the existing production line, this step mostly relies on manual operation by workers, specifically, the worker holds the flashlight barrel with one hand and rotates the head cover with the other hand to tighten it.

[0003] This traditional manual installation method has the following problems: since workers are required to manually rotate the head cover, long-term repetitive labor may cause workers' wrist fatigue and even cause occupational diseases, low production efficiency, and manual operation cannot ensure that the strength and tightness of each installation are completely consistent, which may affect the overall performance of the product and user experience.
