Specific implementation mode
Electric tool 100 shown in FIG. 1 specifically can be with angle grinder, which can be used for the works such as cutting and polish
Make.It is in fact possible to understand, electric tool 100 can also be the tool of other polishing classes such as polishing machine, sander, may be used also
Think the tool of the torsion output class such as electric drill, screwdriver, electric hammer, can also be the tool of the reciprocal class such as reciprocating saw, sweep-saw, also
It can be the tool that electric circular saw, bench saw etc. cut class, can also be the tool of the gardens such as grass-mowing machine, grass trimmer class.
As depicted in figs. 1 and 2, electric tool 100 includes：Shell 11, motor 12, output 13 and switching system 20.
Shell 11 is formed with the handle 111 for being held for user, and 11 inside of shell is around the receiving being formed with for accommodating motor 12
Space.Motor 12 is arranged inside shell 11, and motor 12 is for driving output 13 to export power.It is defeated for angle grinder
Go out part 13 and be specifically as follows output shaft, output shaft can connect the grinding for cutting or polishing etc..Switching system 20 is used for
Control the startup or stopping of motor 12.
As shown in Figures 2 to 6, switching system 20 specifically includes：Switch enclosure 21, pull rod 22 and push button 23, wherein switch
Box 21 is arranged in shell 11, and switch enclosure 21 is constituted with motor 12 and is electrically connected, and pull rod 22 is distinguished at the both ends of its extending direction
Connecting valve box 21 and push button 23 are set on shell 11 there are one sliding area 112, and push button 23 can be slided along 101 direction of first straight line
Dynamic setting is in sliding area 112, so that the sliding that push button 23 is constituted with shell 11 along 101 direction of first straight line connects
It connects.When pushing push button 23 to be slided along 101 direction of first straight line, push button 23 can be slided user with respect to shell 11 from non-trigger position
It moves to trigger position.When push button 23 is in non-trigger position, the pull rod 22 being connect with push button 23 makes switch enclosure 21 is in open
The starting state of dynamic motor 12；And when push button 23 is in trigger position, the pull rod 22 being connect with push button 23 is so that switch enclosure 21
In the off-state for disconnecting motor 12.
Specifically, sliding area 112 is specially the groove 113 that the recess of shell 11 is formed, push button 23 is slidable
It is arranged in groove 113.Opening 113a is also formed in groove 113, push button 23 includes the interconnecting piece 231 across opening 113a,
Interconnecting piece 231 passes through opening 113a to stretch to the part inside shell 11 and constitutes connection with pull rod 22, so that working as push button 23
Pull rod 22 can be driven to be moved along the direction for being parallel to first straight line 101 when being slided along 101 direction of first straight line, so that opening
Box 21 is closed to switch between starting state and off-state.Still further, interconnecting piece 231 is two grab 231a,
Pull rod 22 is formed with can be with the hole 221 of grab 231a cooperations.
Switching system 20 further include for generating one so that the biased element 24 that is moved towards non-trigger position of push button 23,
The biased element 24 is specially the spring being connect with pull rod 22.Spring bias pull rod 22 is moved towards off-state, and pull rod 22 is drawn
Dynamic push button 23 is moved along 101 direction of first straight line towards non-trigger position.
The limit hole 113b for push button 23 to be limited in trigger position is also formed in groove 113, push button 23 is formed with
With the limiting section 232 of limit hole 113b cooperations, when limiting section 232 is inserted into limit hole 113b, both mutual cooperation makes
It obtains limit hole 113b and applies a driving force towards limiting section 232, which makes push button 23 along 101 direction of first straight line
On overcome the biasing force of biased element 24 so that push button 23 is maintained at trigger position.
In the present embodiment, switching system 20 further includes for enabling push button 23 rotatable for axis with first axle 102
The shaft part 25 being arranged in sliding area 112,102 direction of first axle and the push button 23 that shaft part 25 rotates slide the
One straight line, 101 direction is mutually perpendicular to.Shaft part 25 extends along 102 direction of first axle, and shaft part 25 constitutes 23 phase of push button
The fulcrum that shell 11 is moved with first axle 102 for shaft rotation.Push button 23 further includes the first press section 233 for being pressed for user
With the second press section 234, wherein the first press section 233 and the second press section 234 are separately positioned on the both sides of shaft part 25, more
For body, the first press section 233 and limiting section 232 are separately positioned on the both sides of shaft part 25, the second press section 234 and limiting section
232 are arranged the homonymy in shaft part 25.One is additionally provided in groove 113 at limit hole 113b to move for backstop push button 23
Backstop boss 113c.
In this way, when user needs to start motor 12, user can first press the first press section 233 while push 23 edge of push button
101 direction of first straight line overcomes the biasing force of biased element 24 to be moved towards non-trigger position, in this way, push button 23 is straight along first
It is also dynamic for shaft rotation with first axle 102 while 101 direction of line is moved to non-trigger position, so that push button 23 crosses backstop
The backstop of boss 113c, when limiting section 232 is aligned with limit hole 113b, user can press the second press section 234 so that
Push button 23 is rotated in the opposite direction with first axle 102, to which at this moment limiting section 232 is inserted into limit hole 113b, into
And limiting section 232 and limit hole 113b coordinate so that push button 23 is limited in trigger position.And when user needs to disconnect motor 12
When, user can first press the first press section 233 and so that push button 23 is dynamic for shaft rotation with first axle 102, then the limit of push button 23
Position portion 232 will be detached from limit hole 113b, and at this moment under the action of biased element 24, push button 23 is reset to non-trigger position.
Shaft part 25 is also detachably connected with the composition of push button 23, in this way, after 100 long-term operation of electric tool, shaft part
25 will be worn, or when having more dust in the groove 113 of shell 11, dust also can countershaft part 25 generate compared with
Big abrasion.The shaft part 25 being worn is so that push button 23 is inadequate with the stroke that first axle 102 moves for shaft rotation, to influence to use
The feel that family uses, at this moment user can extend the service life of switching system 20 by replacing Independent Observer Program's part 25.
More specifically, shaft part 25 is the straight pin extended along 102 direction of first axle, and interconnecting piece 231 forms useful
In the through-hole 231b for making shaft part 25 pass through.Shaft part 25 may be used the larger material of hardness and be made, and turn so as to extend
The service life of shaft member 25.Shaft part 25, which is specifically as follows, to be made of metal material, such as steel may be used and be made.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent substitution or equivalent transformation
The technical solution obtained, all falls in the scope of protection of the utility model.
