Detailed description of the invention
Below in conjunction with accompanying drawing, describe specific embodiment of the invention scheme in detail.
As Fig. 1, shown in Fig. 2, electric tool switch of the present invention, the button 2 comprising housing 1 and be arranged on outside housing 1, button 2 is provided with push rod 3, one end of push rod 3 is stretched in housing 1, and the push rod 3 being positioned at housing 1 is provided with spring 4, one end of spring 4 and the inwall of housing 1 offset, the upper end of housing 1 is provided with the direction of motion and the perpendicular driving lever 5 of button 2 direction of motion, housing 1 is stretched out at the two ends of driving lever 5 respectively, driving lever 5 side is provided with the torsion spring 7 that driving lever 5 is resetted by snap close 6, two ends of torsion spring 7 are stretched in driving lever 5 respectively, the end face edge place, upper end of button 2 is provided with enclosing 8, button 2 is provided with two blocks---the first block 9 and the second block 10, chute 11 is formed between first block 9 and the second block 10, chute 11 prolong to identical with the direction of motion of button 2, first block 9 and the second block 10 are respectively arranged with the first raised line 12 and the second raised line 13, first raised line 12, the first locating slot 14 is formed between first block 9 and enclosing 8, second raised line 13, the second locating slot 15 is formed between second block 10 and enclosing 8, the middle part of driving lever 5 is provided with the grab 16 matched with the first locating slot 14 and the second locating slot 15.In order to driving lever 5 can reset promptly and accurately, described push rod 3 is positioned on the position outside housing 1 and is provided with guide rail 17, gap 18 is left between guide rail 17 and the inwall of button 2 away from one end of housing 1, release link 19 is provided with between push rod 3 and guide rail 17, the upper end of release link 19 is flexibly connected with the middle part of push rod 3, the middle part of release link 19 is rotated and is arranged on housing 1 outer wall, and namely release link 19 can be rotated around the tie point place of release link 19 and push rod 3 and ensure that release link 19 can also rotation in the middle part of it.The lower end of release link 19 is provided with dovetail groove, and guide rail 17 is arranged in dovetail groove---shown in Fig. 3.
The course of work of electric tool switch of the present invention is: as figure institute 1 shows, when electric tool needs to promote driving lever 5 (namely left-handed person utilizes thumb to promote driving lever 5) locking electric tool duty to the lower right corner, first press the button 2, along with pressing of button 2, the afterbody of grab 16 along chute 11 to button 2 for button 2 on driving lever 5 moves, when grab 16 skids off chute 11, now release link corrects getaway 17 19 times and in gap 18 between guide rail 17 and button 2, then left hand thumb promotes driving lever 5 to the lower right corner, now grab 16 moves to the lower right corner, when grab 16 is positioned at the lower left of the second locating slot 15, release button 2, button 2 is below reset left under the effect of spring 4, but button 2 is when reset, because grab 16 is motionless, snap in the second locating slot 15 immediately, now unclamp left hand thumb, grab 16 cannot enter chute 11 after being blocked by the second raised line 13 and reset, and button 2 does not also reset completely under the stop of grab 16, thus realize the locking of electric tool duty, now button 2 and driving lever 5 are all locked in place.When needs unlock, again press the button 2, grab 16 on driving lever 5 departs from immediately from the second locating slot 15, and break away from the constraint of the second raised line 13, due to driving lever 5 in its direction of motion without constraint, reset under the effect of torsion spring 7, namely grab 16 slips in chute 11, due to the effect of release link 19, grab 16 can accurately slip in chute 11, and button 2 also resets completely under the effect of spring 4 subsequently.If when the people of normal right-handed uses electric tool, method of operating is contrary with above-mentioned introduction, has just repeated no more at this.Above-mentioned electric tool switch well solves the problem of left-handed person inconvenient operation.
