Abstract

The invention discloses a fuse-equipped trigger switch which comprises a housing, a trigger switch and a fuse unit, wherein the trigger switch and the fuse unit are mounted in the housing. The trigger switch comprises a positioning sleeve, a rotor and a torsional spring. The rotor is rotatably connected with the positioning sleeve. Two ends of the torsional spring are respectively arranged on the rotor and the positioning sleeve. The outer periphery of the rotor is provided with a trigger head. One end surface of the rotor is provided with a fuse trough. The fuse unit comprises a blocking pin. One end of the blocking pin extends into the fuse trough and furthermore the blocking pin can be disengaged from the housing along the axial direction. According to the fuse-equipped trigger switch, through arranging the blocking pin, safety insurance is added for a triggering step.

Description

technical field [0001] The invention relates to a mechanical trigger switch structure, in particular to the field of a trigger switch with safety. Background technique [0002] Most of the trigger switches on the market are electric or simple button triggers, which have a high failure rate and do not have a safety device, so they are not suitable for some occasions that require particularly strict reliability. Contents of the invention [0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the present invention provides a trigger switch with insurance and reliable triggering. [0004] Technical solution: In order to achieve the above object, the safety trigger switch of the present invention includes a casing, a trigger switch and a safety unit installed inside the casing; the trigger switch includes a positioning sleeve, a rotor and a torsion spring, and the connection between the rotor and the positioning sleeve The two ends of the to...
