Specific embodiment
Hereinafter, for a more detailed description to the utility model with embodiment combination attached drawing.This embodiment is only to this
The description of utility model preferred forms, does not have any restrictions to the scope of the utility model.
As shown in Figure 1 to Figure 3, a kind of electric tool switch, including push rod 1 and shell 2, the shell 2 is interior to be equipped with circuit
Control panel 3,1 one end of push rod is set in shell 2, and is fixedly connected with regulating part 4, and the other end passes through shell 2, and holding is fixed
There is a button 5, the circuit control panel 3 is set to 4 side of regulating part, and the regulating part 4 is equipped with to be matched with circuit control panel 3
It adjusts the speed piece 41 and touches piece 42, spring 43 is equipped between the regulating part 4 and shell 2.
Regulating part 4 is driven by push rod 1, makes to adjust the speed the position change that piece 41 is in contact with circuit control panel 3, to change
The resistance value for the route being connected to circuit control panel 3, to change the size of current exported in circuit, to change electric tool
Revolving speed speed.
Regulating part 4 is equipped with blocked socket 44 far from one end of circuit control panel 3, and 2 inner wall of shell is equipped with and blocked socket 44
The holding raised line 21 matched.Limit the direction of motion of regulating part 4.
The shell 2 is mutually fastened by two components, fixed by snap.Facilitate the part inside installation shell 2.
It is equipped with dust-proof chamber 22 in the shell 2, is equipped with dustproof sponge 23 in dust-proof chamber 22.The push rod 1 passes through anti-this world
Silk floss 23, the dust of 2 periphery of shell is brought into shell 2 by anti-throw-out lever 1 in the operating condition, protects the component in shell 2.
The shell 2 is equipped with limited block 24, and 24 two sides of limited block are equipped with limiting slot 25, and the button 5 is equipped with and limiting slot
