Abstract
The invention discloses a switch for an electric tool, which is simple in structure and comprises a substrate, a press button articulated on the substrate and a potentiometer arranged on the substrate, wherein a driving lever for controlling the potentiometer to work is arranged in the potentiometer; a torsional spring is arranged at a place at which the press button and the substrate are articulated with each other; steps are respectively arranged on the inner walls of the two sides of the press button, which are positioned at the articulation place; the two ends of the torsional spring are respectively arranged below the corresponding steps, when the press button is pressed down, one end of the torsional spring is in contact with the corresponding step, and a kidney slot is also arranged in the inner wall of the press button; an oscillating bar is also articulated on the substrate; and one end of the oscillating bar is provided with a slotted hole, the oscillating bar is sheathed on the driving lever through the slotted hole, and the other end of the oscillating bar is provided with a bayonet lock which is positioned in the kidney slot in the inner wall of the press button. The switch has the advantages that the oscillating bar is used for controlling the reversing of the potentiometer, the structure is very simple, the machining accuracy requirement of the oscillating bar is very low, and the production cost can be effectively reduced.
Description
Technical field
The present invention relates to a kind of electric tool switch.
Background technology
Existing electric tool switch, comprise pedestal, be hinged on the button on the pedestal and be arranged on potentiometer on the pedestal, be useful on the driving lever of control potentiometer work in the potentiometer, thereby realize being connected the control that realizes potentiometer by gear between button and the potentiometer, because the precision prescribed of gear is higher, and the plastic cement gear can not be realized so high precision, so it is not too flexible in commutation.
Summary of the invention
Technical problem to be solved by this invention is: a kind of electric tool switch simple in structure is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of electric tool switch, comprise pedestal, be hinged on button and the potentiometer that is arranged on the pedestal on the pedestal, be useful on the driving lever of control potentiometer work in the potentiometer, the hinged place of described button and pedestal is provided with torsion spring, button is positioned on the inwall of both sides of hinged place and is respectively arranged with step, the two ends of torsion spring lay respectively at the below of corresponding step and when button is pressed, the one end step corresponding with it of torsion spring contacts, also be provided with kidney slot on the button inwall, also be hinged with fork on the pedestal, one end of fork is provided with mounting hole and is enclosed within on the driving lever by this mounting hole, the other end is provided with bayonet lock, and bayonet lock is arranged in the kidney slot on the button inwall.
Described potentiometer is fastened in the pedestal.
The invention has the beneficial effects as follows: utilize fork to control the commutation of potentiometer, its structure is very simple, and the requirement on machining accuracy of fork is very low, can effectively reduce production costs.
Description of drawings
Fig. 1 is the exploded view of electric tool switch of the present invention;
Fig. 2 is the front view of electric tool switch of the present invention.
Among the figure: 1, pedestal, 2, button, 3, potentiometer, 4, driving lever, 5, torsion spring, 6, step, 7, kidney slot, 8, fork, 9, mounting hole, 10, bayonet lock.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As depicted in figs. 1 and 2, electric tool switch of the present invention, comprise pedestal 1, be hinged on button 2 and the potentiometer 3 that is arranged on the pedestal 1 on the pedestal 1, be useful on the driving lever 4 of control potentiometer 3 work in the potentiometer 3, the hinged place of described button 2 and pedestal 1 is provided with torsion spring 5, button 2 is positioned on the inwall of both sides of hinged place and is respectively arranged with step 6, the two ends of torsion spring 5 lay respectively at the below of corresponding step 6 and when button 2 is pressed, the step 6 that one end of torsion spring 5 is corresponding with it contacts, also be provided with kidney slot 7 on button 2 inwalls, also be hinged with fork 8 on the pedestal 1, one end of fork 8 is provided with mounting hole 9 and is enclosed within on the driving lever 4 by this mounting hole 9, the other end is provided with bayonet lock 10, and bayonet lock 10 is arranged in the kidney slot 7 on button 2 inwalls.For compact conformation, described potentiometer 3 is fastened in the pedestal 1.The electric tool switch of said structure is simple in structure, utilizes the swing of simple fork 8 just can realize the commutation of potentiometer 3.Because when button 2 one ends are pressed, the motion that the step 6 of its this end will overcome torsion spring 5 active forces with an end in contact and the work of torsion spring 5, and the swing of button 2 has realized the swing of fork 8 upper ends, because fork 8 is hinged on the pedestal, so the driving lever 4 that the lower end of fork 8 just drives in the potentiometer 3 rotates, thereby effectively realize the speed-regulating function of potentiometer 3.After speed governing finished, button 2 automatically reset under the effect of torsion spring 5, operates very simple.
Claims (2)
1. electric tool switch, comprise pedestal, be hinged on button and the potentiometer that is arranged on the pedestal on the pedestal, be useful on the driving lever of control potentiometer work in the potentiometer, it is characterized in that: the hinged place of described button and pedestal is provided with torsion spring, button is positioned on the inwall of both sides of hinged place and is respectively arranged with step, the two ends of torsion spring lay respectively at the below of corresponding step and when button is pressed, the one end step corresponding with it of torsion spring contacts, also be provided with kidney slot on the button inwall, also be hinged with fork on the pedestal, one end of fork is provided with mounting hole and is enclosed within on the driving lever by this mounting hole, the other end is provided with bayonet lock, and bayonet lock is arranged in the kidney slot on the button inwall.
