Embodiment

Explanation at length below with reference to Figure of description a kind of welding-cutting tool bat-handle switch of the present invention being done.

Shown in accompanying drawing, a kind of welding-cutting tool bat-handle switch of the present invention, its structure comprises anti-misoperation push button 3, switch loam cake 1, switch lower cover 12, movable slider 4 and touch-pressure switch module 13; Wherein, the centre of switch loam cake 1, switch lower cover 11 is a groove-like, and anti-misoperation push button 3 is arranged on the top of switch loam cake 1; Switch loam cake 1 is buckled in the top of switch lower cover 12, and both left ends link together through hinge axis 11, and right-hand member snaps together through flange 18 each other; The centre of switch loam cake 1 has cylindrical void 16, and the bottom of anti-misoperation push button 3 is provided with transplants a cutting 5, and cutting 5 is passed the blind holes of cylindrical void 16 in the middle of movable slider 4 and is plugged on; Be provided with horizontal reset spring 2 between the right-hand member of the right side of movable slider 4 and switch loam cake 1; The semicircle cambered surface is processed in the bottom of movable slider 4, and the semicircle cambered surface is slidingly connected with the semicircle cambered surface fixed slider 15 that is arranged on the switch lower cover 12, and the left end that is positioned at switch loam cake 1 middle cylindrical void 16 supports 9 to being arranged with one; Support 9 belows and be provided with a seesaw 7; Be provided with vertical reset spring 10 between the left end of the left end of seesaw 7 and switch lower cover 12, the below of seesaw 7 right-hand members is provided with and presses tongue 9, and it is relative with the touch-pressure switch module 13 that is arranged on the switch lower cover 12 to press tongue 9; Seesaw 7 right-hand members also are provided with salient point 6; Salient point 6 matches with the groove of opening above movable slider 4 left side semicircle cambered surfaces, and the right-hand member of switch lower cover 12 bottoms is provided with conductor interface slot 17, and the plug 14 of touch-pressure switch module 13 is positioned in the middle of the conductor interface slot 17.The top of anti-misoperation push button 3 is provided with big boss 19 and small boss 20.

Embodiment
