Abstract
The utility model relates to a switch of electric tool comprising a push rod, a push rod spring and a base, the push rod can be movably and vertically mounted in the base, the push rod is positioned in the center of the base, a movable contact support, a movable contact sheet, a movable contact spring and a static contact sheet are symmetrically and respectively distributed in the bases on two left and right sides of the push rod, lateral wings are distributed at left and right two sides on the push rod symmetrically, the movable contact sheets can be mounted on the movable contact support vertically and swingingly, one end of the movable contact is connected to the lateral wing, the other end of the movable contact spring is connected to the movable contact sheet. Because the movable contact support, the movable contact sheet, the movable contact spring and the static contact sheet are respectively mounted at left and right two sides of the base, said parts layout ensures that the integral height of the switch of electric tool can be reduced greatly, accordingly, the integral dimension of the switch of electric tool is diminished, which is propitious to the electric tool miniaturization, and the utility model is much more suitable for hand holding, the comfortableness of the can be used effectively.
Description
Technical field
The utility model relates to a kind of switch, particularly a kind of electric tool switch.
Background technology
Electric tool switch of the prior art generally comprises push rod, push rod spring and pedestal, push rod is installed in the pedestal up and down movably, also comprise upper and lower sides dynamic/static contact and upper and lower sides spring in the pedestal, one end of upside spring is fixedlyed connected with the upside moving contact, the other end is fixedlyed connected with the push rod upside, one end of downside spring is fixedlyed connected with the downside moving contact, and the other end is fixedlyed connected with the push rod downside.The shortcoming that the electric tool switch of said structure exists is: because upper and lower sides dynamic/static contact and upper and lower sides spring branch stand in the both sides up and down of pedestal, increased the height of pedestal virtually, the height that correspondingly is installed in the push rod in the pedestal also can increase, make the electric tool overall dimensions higher after being installed to electric tool, feel and comfort thereby influence holding of electric tool.
Summary of the invention
In order to solve the shortcoming of above-mentioned electric tool switch, the electric tool switch that the utility model provides a kind of height to reduce.
Technical solution of the present utility model provides a kind of electric tool switch, comprise push rod, push rod spring, pedestal, push rod is installed in the pedestal up and down movably, push rod is positioned at pedestal central authorities, be respectively equipped with moving contact rack, movable contact spring, moving contact spring and the static contact of symmetrical distribution in the pedestal of the push rod left and right sides, the left and right sides is provided with the flank of symmetrical distribution on the push rod, movable contact spring is installed on the moving contact rack up and down swingably, moving contact spring one end is connected to flank, and the moving contact spring other end is connected to movable contact spring.
Because in the above-mentioned technical solution, moving contact rack, movable contact spring, moving contact spring and static contact are installed in the pedestal left and right sides respectively, so component layouts has guaranteed that the electric tool switch whole height reduces greatly, thereby the electric tool switch overall dimensions is diminished, help the electric tool miniaturization, and be fit to staff more and grip, effectively strengthen the comfort level of using electric tool switch.

Embodiment
Below in conjunction with drawings and Examples the utility model is described in further detail.
Extremely shown in Figure 5 as Fig. 1, the embodiment of the utility model electric tool switch, comprise push rod 1, push rod spring 3, pedestal 2, push rod 1 is installed in the pedestal 2 up and down movably, push rod 1 is positioned at pedestal 2 central authorities, be respectively equipped with moving contact rack 4, movable contact spring 5, moving contact spring 6 and the static contact 7 of symmetrical distribution in the pedestal 2 of push rod 1 left and right sides, push rod 1 left and right sides is provided with the flank 8 of symmetrical distribution, movable contact spring 5 is installed on the moving contact rack 4 up and down swingably, moving contact spring 6 one ends are connected to flank 8, and moving contact spring 6 other ends are connected to movable contact spring 7.
In addition, as Fig. 1, Fig. 4, shown in Figure 5, between above-mentioned moving contact spring 6 and flank 8, be provided with pad 10, pad 10 is provided with lower hem 13 and horizontal raised line 14, flank 8 is provided with installing hole 15 up and down, the last lower hem 13 of pad 10 is respectively installed to the installing hole up and down 15 of flank 8, and moving contact spring 6 one ends are connected with the horizontal raised line 14 of pad 10.Owing to be provided with pad 10 between moving contact spring 6 and the flank 8, wearing and tearing reduction between moving contact spring 6 and the flank 8, the useful life of having improved switch, and employed spring can select bigger elastic force, so can improve the action sensitivity of switch.
As Fig. 1, Fig. 2, shown in Figure 3, above-mentioned movable contact spring 5 one ends are back hook, and time hook end hook joint of movable contact spring 5 can further bring the advantage that promotes the electric tool switch reliable in action and rationally utilize the base interior space on moving contact rack 4.
Said structure also can be done following improvement: as Fig. 1, Fig. 4, shown in Figure 5, on described movable contact spring 5 moving contact 9 is set, fixed contact 11 is set on the static contact 7.The sound contact that cooperatively interacts can make the course of action of electric tool switch accurately reliable, and the sensitivity that improves electric tool switch further.
