Problems solved by technology

[0002] In the prior art, the trigger protection switch is generally set at a position where the operator’s index finger is inconvenient to touch. When operating the protection switch device, two hands are required to complete the operation, which is laborious, time-consuming and inconvenient.
Especially when the protection state is suddenly released and the index finger is still on the trigger, it is extremely easy to misuse and cause serious consequences
At the same time, the trigger switch in the protected state, the trigger cannot be moved during operation

Abstract

The invention discloses a trigger switch, which relates to the trigger switch device field. The trigger switch comprises a housing, a protection switch, a switch rotation shaft, a trigger, a trigger rotation shaft and a torsion spring. The protection switch comprises a switch crank and a switch gap wherein the switch crank is installed inside the housing by the switch rotation shaft and the switch gap is arranged at one end of the switch crank. The trigger is arranged at the inner side of the housing by the trigger rotation shaft. One side of the trigger close to the switch gap is provided with a boss. Through the rotation of the switch crank and the trigger, it is possible to move the boss of the trigger to the inner part of the switch gap. The torsion spring is fixedly arranged between the inner side of the housing and the trigger. The design of the trigger switch of the invention allows simple, safe and reliable operations. Just with one index finger, a user of the trigger switch can complete the buckling of the trigger and the switching between the locked state and the free state of the protection switch. Particularly, when relieving the dead-lock state, the index finger of the user has to be lifted by some angle from the trigger, which effectively avoids the erroneous contact in the use of the trigger.

Description

technical field [0001] The invention relates to the field of trigger switch devices, in particular to a trigger switch. Background technique [0002] In the prior art, the trigger protection switch is generally set at a position where the operator's index finger is inconvenient to touch. Two hands are required to operate the protection switch device, and the operation is laborious, time-consuming and inconvenient. Especially when the protection state is suddenly released and the index finger is still on the trigger, it is extremely easy to misuse and cause serious consequences. At the same time, the trigger switch in the protected state cannot be operated during operation. Contents of the invention [0003] In view of this, the present invention has designed and completed a set of trigger switch, which has the characteristics of simple operation, safety and reliability, etc. The user of the trigger switch only needs to use the index finger of one hand to pull the trigger ...
