Detailed description of the invention
Below in conjunction with accompanying drawing and embodiment shown in the drawings, the invention will be further described.
As shown in Figure 1, electric tool of the present invention comprises: body 103, body 103 is formed primarily of motor casing 105, transmission mechanism shell 107 and rear cap 131, motor casing 105 and rear cap 131 form the function with the handle portion grasped jointly, transmission mechanism shell 107 is connected to the leading section of motor casing 105, being filled with Poewr transmission mechanism 111 in this transmission mechanism shell 107 adduction, being delivered to emery wheel 119 for the rotation of motor 121 being exported.In present embodiment, be transported to be driven on motor 121 with power line 160 by the electric power of power supply, this motor 121 is primarily of output shaft 123, fan blade 124, armature 125, stator 127, commutator 129 and two carbon brush, and carbon brush holder is formed; Rear cap 131 is fixed on motor casing 105 by screw 132, and this motor casing 105 forms the handle portion 110 grasped for user of service jointly with rear cap 131.This handle portion 110 has certain length in the longitudinal direction, and user of service can be allowed can to grasp side by side with before and after two hands.This rear cap 131 adduction is filled with switch portion 141 in addition, this switch portion 141 is for "on" position (open mode) and the off-position (closed condition) of switch motor 121, this switch portion 141 arranges action bars 143, for opening and the operation of closing this switch portion 141.This this action bars 143 external is provided with the lockable mechanism 180 that can prevent this action bars 143 maloperation.Aforesaid operations bar 143 and lockable mechanism 180 constitute the operating parts in the present invention jointly.
As shown in Figure 2, electric tool lockable mechanism 180 the 1st duty of the present invention, 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 invention, after lockable mechanism switches 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, thus cancels the locking to action bars 143.
As shown in Figure 4, electric tool locking mechanism 152 of the present invention comprises: self-locking briquetting 152a, rotating shaft 152b, briquetting button 152c, spring members 153, holding section 143b.Wherein locking mechanism 152 can adjust the motion state of action bars 143; When with hand operated self-locking briquetting 152a, and rotate centered by rotating shaft 152b, when reaching holding section 143b and briquetting button 152c position, being locked in on-state by action bars 143, making switch portion 141 for long-time on-state.Same operating personnel is by operation action bars 143, and cause holding section 143b to leave the buckle scope of briquetting button 152c, the resistance of holding section 143b to briquetting button 152c is removed, 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 present invention still has multiple concrete embodiment.All employings are equal to replacement or equivalent transformation and all technical schemes of being formed, all drop within the scope of protection of present invention.
