[0030] The control switch assembly 4 includes a connector 41, a handle 42, and a control switch (not shown). The connector 41 is connected to the handheld part 2, and the handle 42 is movably connected to the connector 41 and can rotate within the plane of the side wall of the handheld part 2. The control switch is mounted on the handle 42 and is used to control the start and stop of the laser output from the welding torch head 1, so that the handle 42 can rotate within a range of less than or equal to 360°, thereby allowing the operator to operate the control switch at any angle. This utility model provides an easy-to-operate handheld laser welding gun. The control switch assembly 4 is used to control the operation or stop of the welding gun head 1. The handle 42 is movably connected to the connecting body 41, that is, the handle 42 can rotate relative to the handheld part 2. The handle 42 can rotate within the plane of the side wall of the handheld part 2, thereby allowing the handle 42 to rotate within a range of less than or equal to 360°, thereby changing the position of the control switch. This allows the operator to operate the control switch from any angle, thus realizing the operation or stop of the welding gun head 1. This avoids the operator from controlling the gun in the same position for a long time. It can also meet the needs of operators with different operating habits, including left-handed operators, improving overall operability, reducing operator fatigue, and improving operating comfort and work efficiency. This solves the technical problem in the prior art where the button position on the handheld laser welding gun is not adjustable, and the operator fatigue caused by operating in the same position for a long time.

[0031] As an optional implementation, the control switch assembly 4 includes a handle 42, a rotating plate 43, a connector 44, and a spring 45.
