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, the potentiometer comprising pedestal, be hinged on the button on pedestal and be arranged on pedestal, the driving lever for the work of controlling potential device is had in potentiometer, realize being connected by gear between button with potentiometer thus realize the control of potentiometer, because the precision prescribed of gear is higher, and plastic cement gear can not realize so high precision, therefore it is not too flexible when commutation.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of structure simple electric tool switch.
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, the potentiometer being hinged on the button on pedestal and being arranged on pedestal, the driving lever for the work of controlling potential device is had in potentiometer, the hinged place of described button and pedestal is provided with torsion spring, the inwall that button is positioned at the both sides of hinged place is respectively arranged with step, the two ends of torsion spring lay respectively at corresponding step below and when button is pressed, the step that one end of torsion spring is corresponding with it contacts, button inwall is also provided with kidney slot, pedestal is also hinged with fork, one end of fork is provided with mounting hole and is enclosed within driving lever by this mounting hole, the other end is provided with bayonet lock, bayonet lock is arranged in the kidney slot on button inwall.
Described potentiometer is fastened in pedestal.
The invention has the beneficial effects as follows: utilize fork to carry out the commutation of controlling potential device, its structure is very simple, and the requirement on machining accuracy of fork is very low, effectively can reduce production cost.

Fig. 2 is the front view of electric tool switch of the present invention.
In 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.
Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As depicted in figs. 1 and 2, electric tool switch of the present invention, comprise pedestal 1, the potentiometer 3 being hinged on the button 2 on pedestal 1 and being arranged on pedestal 1, the driving lever 4 worked for controlling potential device 3 is had in potentiometer 3, the hinged place of described button 2 and pedestal 1 is provided with torsion spring 5, the inwall that button 2 is positioned at the both sides of hinged place is respectively arranged with step 6, the two ends of torsion spring 5 lay respectively at corresponding step 6 below and when button 2 is pressed, the step 6 that one end of torsion spring 5 is corresponding with it contacts, button 2 inwall is also provided with kidney slot 7, pedestal 1 is also hinged with fork 8, one end of fork 8 is provided with mounting hole 9 and is enclosed within driving lever 4 by this mounting hole 9, the other end is provided with bayonet lock 10, bayonet lock 10 is arranged in the kidney slot 7 on button 2 inwall.In order to compact conformation, described potentiometer 3 is fastened in pedestal 1.The electric tool switch structure of said structure is simple, utilizes the swing of simple fork 8 just can realize the commutation of potentiometer 3.Because when button 2 one end is pressed, the step 6 of its this end also will do the motion overcoming torsion spring 5 active force with the end thereof contacts of torsion spring 5, and the swing of button 2 achieves the swing of fork 8 upper end, because fork 8 is hinged on pedestal, so the lower end of fork 8 just drives the driving lever 4 in potentiometer 3 to rotate, thus effectively realize the speed-regulating function of potentiometer 3.After speed governing terminates, button 2 automatically resets under the effect of torsion spring 5, operates very simple.
Claims (2)
1. electric tool switch, comprise pedestal, the potentiometer being hinged on the button on pedestal and being arranged on pedestal, the driving lever for the work of controlling potential device is had in potentiometer, it is characterized in that: the hinged place of described button and pedestal is provided with torsion spring, the inwall that button is positioned at the both sides of hinged place is respectively arranged with step, the two ends of torsion spring lay respectively at corresponding step below and when button is pressed, the step that one end of torsion spring is corresponding with it contacts, button inwall is also provided with kidney slot, pedestal is also hinged with fork, one end of fork is provided with mounting hole and is enclosed within driving lever by this mounting hole, the other end is provided with bayonet lock, bayonet lock is arranged in the kidney slot on button inwall.
