Description

Trigger switch structure

The present invention relates to a trigger switching structure, and in particular relates to a situation in which it is necessary to use two-hand operation and switch the click or continuous firing state, and prevent external factors from dialing the paddles, causing a false alarm.

According to the advancement and development of science and technology, traditional hand tools have been used to achieve disassembly or assembly of small power hand tools without the need for force. There are more and more types of small power hand tools available for users to choose from. . Most of the small power hand tools have the advantages of being versatile, fast, and easy to carry, and for the safety of the user, even safety devices or leak-proof, automatic power-off devices are added to enhance the small power. Hand tool security. There are many types of small power hand tools available on the market today, such as nailing machines, wire saws, electric drills, etc., and the nailing machine is exemplified as a prior art embodiment of the present invention.

Please refer to the Republic of China Patent No. 294096 "nailing machine adjustable click device", this creation is about a nailing machine adjustable click device, which is made up of a pick, a lever and a turn The block is configured, wherein the paddle is disposed in the trigger, and the lower two sides are pivotally coupled with the inner surface of the trigger.
