The specific embodiment
Below in conjunction with accompanying drawing and embodiment shown in the drawings, the utility model will be further described.
As shown in Figure 1, electric tool of the present utility model comprises: body 103, body 103 is mainly made up of motor casing 105, transmission mechanism shell 107 and rear cap 131, motor casing 105 and the common function with the handle portion that grasps use that forms of rear cap 131, transmission mechanism shell 107 is connected to the leading section of motor casing 105, filling Poewr transmission mechanism 111 in the interior receipts of this transmission mechanism shell 107, for the rotation output of motor 121 is delivered to emery wheel 119.In present embodiment, the electric power of power supply is transported on motor 121 to be driven with power line 160, this motor 121 is mainly by output shaft 123, fan blade 124, armature 125, stator 127, commutator 129 and two carbon brush, and carbon brush holder forms; Rear cap 131 is fixed on motor casing 105 by screw 132, and this motor casing 105 forms with rear cap 131 handle portion 110 grasping for user of service jointly.This handle portion 110 has certain length in the longitudinal direction, can allow user of service grasp side by side with two hands front and back.The interior receipts of this rear cap 131 are filling switch portion 141 in addition, this switch portion 141 is for the "on" position (open mode) and off-position (closed condition) of switch motor 121, in this switch portion 141, action bars 143 is being set, for this switch portion 141 is opened and the operation of closing.This external this action bars 143 is provided with the lockable mechanism 180 that can prevent these action bars 143 maloperations.Aforesaid operations bar 143 has formed the operating parts in the utility model jointly with lockable mechanism 180.
As shown in Figure 2, electric tool lockable mechanism 180 the 1st duty of the present utility model, lockable mechanism locking column 180f is between action bars salient point 143c and casing salient point 105c, thus restriction action bars 143 moves.
As shown in Figure 3, electric tool lockable mechanism 180 the 2nd duty of the present utility model, when lockable mechanism switches after post 180a change in location, lockable mechanism convex surface 180d coordinates with lockable mechanism concave surface 180c lockable mechanism locking column 180f is departed between action bars salient point 143c and casing salient point 105c, thereby cancels the locking to action bars 143.
As shown in Figure 4, electric tool locking mechanism 152 of the present utility model comprises: self-locking briquetting 152a, rotating shaft 152b, briquetting button 152c, spring members 153, holding section 143b.Wherein locking mechanism 152 can be adjusted the motion state of action bars 143; When using hand operated self-locking briquetting 152a, and rotate centered by rotating shaft 152b, in the time reaching holding section 143b and briquetting button 152c position, be locked in on-state by action bars 143, make switch portion 141 for long-time on-state.Same operating personnel by operating operation bar 143, causes holding section 143b to leave the buckle scope of briquetting button 152c, and holding section 143b is disengaged the resistance of briquetting button 152c, and at this moment, under the effect of the elastic force of spring members 153, locking mechanism 152 sets back.
Except above-mentioned preferred embodiment, the utility model still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of forming, within all dropping on the claimed scope of the utility model.
