In figure: 1, housing, 2, push rod, 3, button, 4, spring, 5, step, 6, block, 7, back-off, 8, cover plate, 9, screw, 10, catch, 11, shell fragment, 12, plug wire mouth.
Embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present utility model in detail.
As shown in Figure 1, switch in electric tool described in the utility model, comprise housing 1, the interior slip of described housing 1 is provided with push rod 2, housing 1 is stretched out in one end of push rod 2, and be arranged with button 3 at this end, the other end of push rod 2 is arranged in housing 1, and that end that is positioned at housing 1 at push rod 2 is provided with spring 4, the inwall of the other end of spring 4 and housing 1 offsets, that end that described push rod 2 contacts with button 1 is provided with step 5, on button 3, be provided with the block 6 offseting with step 5, on push rod 2, being provided with cross section is leg-of-mutton back-off 7, block 6 is between step 5 and back-off 7.For easy for installation firm with clamping, the cross section of described back-off 7 is right-angled triangle, and a right-angle side of right-angled triangle overlaps with the outer wall of push rod 2, and another right-angle side is perpendicular to push rod 2 outer walls and near block 6, back-off 7 and step 5 clamp block 6.
As shown in Figure 2 and Figure 3, in housing 1, be provided with cover plate 8, on cover plate 8, be provided with screw fixing wire 9 and several clamping devices that wire is clamped, clamping device comprises catch 10 and the shell fragment 11 that is arranged on catch 10 1 sides, and shell fragment 11 is provided with V-arrangement plug wire mouth 12 near that end of catch 10.
The utility model has the advantages that: the end of push rod 2 is inserted in button 3 by force, utilize the combination of back-off 7 and step 5, block on button 36 is clamped, make the button 3 of switch and push rod 2 can be effectively, closely, firmly link together, even if user, in extreme environment for use, still can normally use.In described switch, need wire interconnecting piece subelement, in the time that wire is fixing, on shell fragment 11, offer after V-arrangement plug wire mouth 12, after making wire fixing by screw 9, shell fragment 11 is locked all the other positions of wire securely by this plug wire mouth 12 and catch, prevent wire dropping, the stability of the switch greatly improving.
