Description
Technical field
The present invention relates to a kind of electric tool switch, particularly a kind of electric tool switch of poke-rod type.
Background technology
The kind of electric tool switch is a lot, and wherein a kind of poke-rod type electric tool switch just comprises housing, lid, driving lever, contact and contact; The contact power supply that is pivotably connected picks out on the terminal, and the contact is divided into fixed contact and moving contact, and wherein fixed contact is arranged on enclosure interior; Be connected with power access end, on the contact that moving contact is provided with, an end of driving lever contacts with said contact; The while driving lever passes lid and is exposed to outside the lid, pulls driving lever, and move on contact the end of driving lever; Make contact swing, make in moving contact and the housing on the contact the fixed contact contact or separate, to reach the purpose of mains switch.The poke-rod type switch of this structure is stirred driving lever and is very easy to, and therefore, fail safe is relatively poor, and particularly for children, children's curious nature tend to toggle switch, and the operator is because misoperation or the like all can cause security incident sometimes.For electric tool switch, safety guard is set above that, be the development trend in this area.Simultaneously, the switch of this structure, when stirring driving lever, feel is bad, and the sensation irregularity is smooth.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem that the present invention will solve provides a kind of poke-rod type electric tool switch that safety guarantee is arranged.
For this reason, the present invention adopts following technical scheme to realize: a kind of poke-rod type electric tool switch comprises housing, lid, driving lever and contact; Said cover cap is on said housing, and said driving lever contacts with said contact with an end, and the other end passes said lid and is exposed to outside the said lid; Said contact picks out terminal with power supply and is connected, and is provided with moving contact in the end of contact, is provided with fixed contact in the said housing; This fixed contact is connected with said power access end; It is characterized in that driving lever is provided with first bearing pin, said lid inboard is provided with protruding step, and the table top of said step is an arc surface.
Said driving lever is provided with through hole, in said through hole, is provided with spring, and in through hole, is provided with feeler lever, and said driving lever contacts with said contact through feeler lever.
Said driving lever is provided with the ball capitulum, and said first bearing pin is arranged on the said ball capitulum.
Two madial walls of said housing are provided with pedestal, and the table top of said pedestal is the arc surface of indent, and said driving lever is provided with second bearing pin, and said second bearing pin places on the table top of said pedestal when work.
This structure of the present invention, owing to step is set in the lid inboard, and after first bearing pin is set on the driving lever, when not working; First bearing pin places in the groove of step and lid body, and can't stir driving lever this moment, driving lever to be pressed, make that first bearing pin on the driving lever breaks away from described groove after; After placing the table top of step, just can stir driving lever, this structure; Prevented misoperation effectively, and children can not arbitrarily stir driving lever, avoid the generation of security incident.

Embodiment
With reference to accompanying drawing; This poke-rod type electric tool switch comprises housing 1, lid 6, driving lever 3 and contact 8, and said lid 6 covers on said housing 1; Said driving lever 3 is provided with through hole 4; In said through hole 4, be provided with spring 5, and in through hole 4, be provided with feeler lever 7, said driving lever 3 contacts with said contact 8 through feeler lever 7.Spring 5 has certain compression degree when mounted, and therefore, the elastic force of spring 5 ejects feeler lever 7 and contacts with contact 8, so feeler lever 7 well contacts with contact 8 all the time, and also steadily smooth when pushing.The other end of driving lever 3 passes said lid 6 and is exposed to outside the said lid 6, and said contact 8 picks out terminal 2 with power supply and is connected, and is provided with moving contact 9 in the end of contact 8; Be provided with fixed contact 10 in the said housing 1, this fixed contact 10 is connected with said power access end 11, on the said driving lever 3 ball capitulum 14 is set; Said ball capitulum 14 is provided with first bearing pin 15, and said lid 6 inboards are provided with protruding step 12, and the table top of said step 12 is an arc surface; Protruding simultaneously step 12 forms a groove 13 with lid 6 bodies, and this electric tool switch is not under working condition, and first bearing pin 15 just places in this groove 13; Therefore, stir driving lever 3 this moment, because the activity space of driving lever 3 is restricted; Just can't stir, prevent effectively that misoperation and children from disorderly dialling and the security incident that causes.When this electric tool switch is controlled, push driving lever 3, after first bearing pin 15 on the driving lever 3 breaks away from described groove 13; " climb " on the table top of step 12, and the table top of step 12 is an arc surface, stirs driving lever 3 this moment; First bearing pin 15 is moved on the circular arc table top of step 12, therefore can easily stir driving lever 3, make feeler lever 7 move left and right on contact 8 on the driving lever 3; When feeler lever 7 on the driving lever 3 when the left end of contact 8 moves on to right-hand member, make contact 8 with power access end for a spot wobble, make the right-hand member of contact 8 fall; Make the moving contact 9 on the contact 8 contact with housing 1 interior fixed contact 10, thus turn-on power; When feeler lever 7 on the driving lever 3 is mobile from right to left side on contact 8, make contact 8 an end perk of moving contacts 9 is installed and break away from fixed contact 10, thus deenergization, the purpose that so just reaches out and close; Left end among this paper and right-hand member are according to the drawing direction.And when pressing driving lever 3, spring 5 pressurizeds in driving lever 3 through holes 4, the elastic force of spring 5 tightly withstands contact 8 with feeler lever 7; Make when driving lever 3 is stirred; The power of will stirring is sent on the contact 8 effectively, swings on the terminal 2 fast and contact 8 is picked out at power supply, to reach rapid switching purposes.After driving lever 3 is stirred to the right; First bearing pin 15 on the driving lever 3 will break away from the circular arc table top of step 12; Drop to again in the described groove 13, the purpose of once more driving lever 3 being pinned is to guarantee the fail safe of electric tool switch; Effectively avoid misoperation or children's the operation that is not intended to, make the work of electric tool have high fail safe.Two madial walls of said housing 1 are provided with pedestal 17, and the table top of said pedestal 17 is the arc surface 18 of indent, is provided with second bearing pin 16 near the bottom on the said driving lever 3, and said second bearing pin 16 places on the table top 18 of said pedestal 17 when work.After driving lever 3 was pushed, second bearing pin 16 on the driving lever 3 just dropped on the arc surface pedestal 17 of indent of 1 liang of madial wall of housing, like this; After driving lever 3 is stirred, can be along the track swing of setting, contact 8 is out of shape owing to overexert to prevent to press driving lever 3; Simultaneously, driving lever 3 is easily swung, therefore; The electric tool switch of this structure, be very long its useful life.
