The structure of the utility model, when the operation workman operates electric tool, must move earlier and push away the button for the promotion lock banking stop, the cavity that makes the lock banking stop be arranged in the handle totally just can be pressed the handle and promote slide bar conduction switch, has stopped children and has at will pressed down the defect that switch start -up electric tool just can be opened to the handle, in order to guarantee the security of electric tool when operating.
Description
Technical field
This utility model relates to the improvement invention of a kind of on and off switch, and the switch referring more particularly to electric tool improves.
Background technology
Electric tool switch is a kind of on and off switch, the special switch on the instruments such as electric tool such as drilling machine, electric drill, electric hammer.For the insecurity preventing maloperation from bringing, drag hook key is typically set on switch knob to reach anti-self locking function, when using this structure, needs to hook backward with hands to draw, use and be inconvenient for.Thus, those skilled in the art has invented a kind of switch preventing self-lock gear of electric tools, its concrete structure is as follows: be provided with cavity volume on the handle of switch, being provided with lock banking stop in cavity volume, connected the bottom of lock banking stop by push rod, push rod is provided with press section and spring, spring is between press section and housing, moving lock banking stop to reach released state by pressing push rod, when resting, spring recovers initial condition thus realizes lock-out state.But the spring on the push rod of this structure exposes in atmosphere, it is easy to gets rusty and damages, and between the lock part of this electric tool switch and lock groove, lifting surface area is little, it is easy to wearing and tearing mutually, be unfavorable for life-time service.
Summary of the invention
The deficiency existed in view of background technology, the technical problem to be solved in the present invention is to provide the electric tool switch of a kind of simple in construction operation safety.
For this, this utility model adopts the following technical scheme that and realizes: a kind of electric tool switch, including housing, slide bar, hands handle, described handle is connected on described slide bar, on described slide bar, feeler lever is installed, stationary contact and movable contact spring it is provided with in described housing, described slide bar is slidably mounted in described housing, described handle is provided with cavity volume, it is provided with lock banking stop in described cavity volume, the side of described lock banking stop is provided with lock groove, described handle body part is positioned at the top of described lock groove, it is characterized in that: described housing is provided with push button and the groove mated with described push button moving line, described push button is connected with the described sheet that is connected, described connection sheet is connected with described lock banking stop.
Described lock banking stop is provided with through hole, and described connection sheet is connected through described through hole with described lock banking stop.
Described lock groove is arcuation groove, and described handle has the sidewall of chamber portion and has the arc lock part of and arcuation groove match.
Described connection sheet is provided with spring, and described spring is connected with described housing.
This structure of the present utility model is used on electric tool, when not in use, effect due to spring, lock banking stop is promoted to be in heeling condition, during pressing handle, the lock groove that the lock part of the chamber portion body of handle is just locked out on sheet blocks, make the slide bar can not be descending, thus switch is constantly in lock-out state, thus the fabulous insecurity preventing maloperation to bring, and lock part of the present utility model is big with the contact area of lock groove, effectively prevent its abrasion brought because of improper use thus extend the service life of electric tool switch, and the setting of push button, compensate for push rod spring especially and be exposed to the outer shortcoming being easily damaged, improve the quality of electric tool switch, this utility model structure is the simplest, operation is very easy, apply on electric tool, there is good using effect.

Detailed description of the invention
Referring to the drawings, this electric tool switch, including housing 7, slide bar 2, handle 1, handle 1 is connected on slide bar 2, feeler lever 3 is installed on slide bar 2, stationary contact 4 and movable contact spring 5 it is provided with in housing 7, slide bar 2 is slidably mounted in housing 7, handle 1 is provided with cavity volume 13, lock banking stop 10 it is provided with in cavity volume 13, the side of lock banking stop 10 is provided with lock groove 11, handle 1 body part is positioned at the top of lock groove 11, it is characterized in that: housing 7 is provided with push button 8 and the groove 14 mated with push button moving line, push button 8 is connected with being connected sheet 9, connect sheet 9 to be connected with lock banking stop 10.
When switch is in and does not uses state, elastic force effect due to spring 16, promotion connection sheet 9 is moved laterally, and then drives push button 8 to move laterally, thus move with lock banking stop 10, lock banking stop 10 is positioned in the cavity volume 13 of handle 1 obliquely, when depressing handle 1, the lock groove 11 that handle 1 body is just locked out on sheet 10 blocks, thus slide bar 2 just can not be descending, electric tool switch can not be turned on, be in self-locking state；The electric tool switch of this structure, is in close contact between lock groove 11 and lock part 12, and contact area is big, the most durable in use, and the insecurity that can effectively prevent maloperation from bringing, for child, there is preferable preventive effect.During work, push button 8 is promoted toward housing central section, push button 8 moves inward with the bottom of lock banking stop 10, make lock banking stop 10 be in vertical state, now, depress handle 1, the lock groove 11 that handle 1 body just will not be locked out on sheet 10 is stopped, descending with slide bar 2, to turn on switch, it is in released state.During release handle 1, due to the effect of compression spring 6, after reset, will be up with slide bar 2 and handle 1, up put in place after, the reset of spring 16, make again lock banking stop 10 be in heeling condition, be in the most again self-locking state.
Push button 8 is connected with the bottom of lock banking stop 10 by connecting sheet 9, push button 8 fixes connection with being connected sheet 9, connect sheet 9 side to be connected with housing 7 by spring 16, connect sheet 10 cross section in " Q " type structure, connect sheet 10 upper end and pass through hole 15 and lock banking stop 10 compact siro spinning technology of lock banking stop 10, each modular construction of this attachment structure is simple, and its assembling is the most simple and convenient.
The sidewall on handle 1 with cavity 13 part has the lock part 12 of an arcuation; lock part 12 matches with the lock groove 11 of arcuate structure; can effectively lock; make lock part 12 can be locked out groove 11 securely to block; and in life-time service; owing to lock groove 11 is relatively big with the contact area of lock part 12, it is possible to prevent its abrasion caused because of stress, protects locking structure.
