Description
Technical field
The utility model relates to a kind of electric tool switch, the anti-self-locking mechanism of particularly a kind of electric tool switch.
Background technology
In order to prevent misoperation, electric tool switch of the prior art generally can be provided with anti-self-locking mechanism, usually adopting to be provided with to collude on switch knob draws key to reach the function of anti-self-locking, when using the anti-self-locking mechanism of this structure, need collude backward with hand and draw, it is very inconvenient to use, and the back that puts on one's gloves is especially used to collude and drawn key just more inconvenient.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of anti-self-locking mechanism of convenient and labor-saving electric tool switch that uses.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: the anti-self-locking mechanism of a kind of electric tool switch, comprise switch knob, switch panel, the rear end of switch knob and the rear end of switch panel are hinged, the front end of described switch panel is provided with the lock platform, the front end of described switch knob is provided with slidably push button of horizontal direction, stretch out outside the switch knob rear end of push button, the front end of push button is provided with and locks the lock top that platform matches, and is provided with holddown spring between the front end of push button and the switch knob.
The beneficial effect of the anti-self-locking mechanism of the utility model electric tool switch is: because the front end of described switch knob is provided with slidably push button of horizontal direction, during use, promote push button forward, can make switch be in released state, electric tool switch in use itself has the power that promotes forward, therefore uses convenient and labor-saving.
The utility model will be further described below in conjunction with the drawings and specific embodiments.

Fig. 2 is the switch knob and the switch panel articulated structure signal partial sectional view of the anti-self-locking mechanism of electric tool switch among Fig. 1.
Fig. 3 is that the anti-self-locking mechanism of electric tool switch is in the lock state the structural representation partial sectional view among Fig. 1.
Fig. 4 is that the anti-self-locking mechanism of electric tool switch is in released state structural representation partial sectional view among Fig. 1.
Embodiment
As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, a kind of embodiment of the anti-self-locking mechanism of the utility model electric tool switch, comprise switch knob 5, switch panel 8, the rear end of the rear end of switch knob 5 and switch panel 8 is hinged, the front end of described switch panel 8 is provided with lock platform 7, the front end of described switch knob 5 is provided with slidably push button 4 of horizontal direction, stretch out outside the switch knob 5 rear end of push button 4, the front end of push button 4 is provided with and locks the lock top 6 that platform 7 matches, and is provided with holddown spring 2 between the front end of push button 4 and the switch knob 5.In order to make structure compact more, the front end of described push button 4 can be provided with spring eye 3, the front end of switch knob 5 is provided with push button jump ring 1, push button jump ring 1 is fixedly mounted on the switch knob 5, one end of holddown spring 2 is fixed in the spring eye 3 of push button 4, and the other end of holddown spring 2 is fixed on the push button jump ring 1.In order to make the switch profile more attractive in appearance, the rear end of described switch panel 8 can be provided with holder 9, the both sides of holder 9 are respectively equipped with pin-and-hole 11, be respectively equipped with the projection 12 that matches with pin-and-hole 11 on the both sides inwall of switch knob 5 rear ends and holder 9 opposite positions, projection 12 on the switch knob 5 both sides inwalls is installed in the both sides pin-and-hole 11 of holder 9, can realize the hinged of switch knob 5 and switch panel 8, because the outside of switch knob 5 no longer includes pin-and-hole, so the switch outward appearance obviously improves.For more convenient to install, the end face both sides of described holder 9 can be respectively equipped with slope 10, the bottom of described both sides projection 12 is respectively equipped with oblique angle 13, during installation, with the end face sloped sides 10 of oblique angle, the bottom 13 secured in alignment seats 9 of both sides projection 12, pin switch knob 5 and push away downwards, under the mating reaction on oblique angle 13 and slope 10, utilize the elasticity of switch knob 5 sidewalls, can like a cork the projection 12 on the switch knob 5 both sides inwalls be installed in the both sides pin-and-hole 11 of holder 9.
The operation principle of the anti-self-locking mechanism of the utility model electric tool switch is: as shown in Figure 3, under the effect of holddown spring 2, push button 4 moves backward, and this moment, the lock top 6 of push button 4 propped up lock platform 7, and switch knob 5 can not move downward, and promptly switch is in the lock state; During use, promote push button 4 forward, push button 4 drives lock top 6 and travels forward, and this moment staggers mutually with lock platform 7 in the lock top 6 of push button 4, and switch knob 5 can freely move downward, and promptly switch is in released state, as shown in Figure 4.
