Abstract

The utility model discloses a handhold electric tool, which comprises a motor arranged in a tool main body, a hand lever connected on the tool main body, and a handle switch mechanism arranged on the holding portion of the hand lever. The handle switch mechanism comprises a switch for controlling a motor circuit to cut in and out and a trigger which triggers the switch to start. The switch is directly fixed on the trigger while the inside of the holding portion of the hand lever has a trigger rib which is relatively arranged to a contact point on the switch. In the utility model, as the switch in the handle switch mechanism is directly arranged on the trigger, the integral structure of the handle switch mechanism is substantially simplified, the space in the holding portion of the hand lever is completely saved in order to conveniently arrange other mechanisms, the bulk of the integral hand lever does not need to enlarge like the prior art, people can feel comfortable and convenient when in holding and operating.

Description

Hand held electric tool

Technical field

The utility model relates to a kind of hand held electric tool.

Background technology

Conventional hand held electric tool comprises tool body, be located at the motor of tool body inside and be connected on the tool body and by motor-driven work package, usually all be provided with handle on the described tool body, handle inside is provided with the switch of control motor circuit break-make, then is provided with to be used for the trigger that trigger switch is opened on handle.

Yet above-mentioned existing hand held electric tool shortcoming is as follows: originally seem more crowded with regard to narrow and small handle inner space because switch is set directly at inner the making of handle, and be unfavorable for the design of some other mechanism; And be the volume that increases handle integral body to the conventional solution of this problem at present, but increasing the handle overall volume but can cause the also corresponding increase of holding area volume on the handle, and it is very uncomfortable that people's holding operation is got up.

Summary of the invention

The utility model purpose is: a kind of hand held electric tool is provided, and the bat-handle switch mechanism structure in this hand held electric tool is simple, save the space, and holding operation gets up more comfortable.

The technical solution of the utility model is: a kind of hand held electric tool, comprise the motor be located in the tool body, be connected the handle on the tool body and be located at bat-handle switch mechanism on this handle grip position, this bat-handle switch mechanism comprises the switch of control motor circuit break-make and triggers the trigger of this switch open; Described switch directly is fixed on the trigger, is provided with the relative triggering muscle in the contact on this switch in the described handle grip position simultaneously.

Trigger described in the utility model is by pivotally connected on handle, and this trigger portion snaps in the cavity of inside, handle grip position; Also be provided with container cavity on the trigger simultaneously, and described switch is fixed on the trigger by alignment pin, and is absorbed in this container cavity.Switch further is located in the container cavity on the trigger can better saves handle grip position volume inside, reduce the volume at handle grip position, it is more comfortable that people's holding operation is got up.

Bat-handle switch mechanism described in the utility model comprises that also one is convenient to the elastic component that resets after the trigger activity, the preferred back-moving spring of this elastic component, and an end of this back-moving spring is against on the spring base that is formed in the handle grip position, and the other end then is against on the trigger.

This hand held electric tool described in the utility model, it is when operation, and staff is held on the handle grip position, drives the switch activity by the clinching trigger, connect motor circuit behind the triggering muscle in the handle grip position is touched in the contact on the switch, make the electric tool operate as normal.And behind the staff releasing trigger, trigger resets under the elastic force effect of elastic component, and muscle cuts off motor circuit thereby triggering is left in the contact on the switch, quits work.

The utility model advantage is:

This hand held electric tool described in the utility model, because the switch in the bat-handle switch mechanism is set directly on the trigger, simplified the structure of bat-handle switch mechanism integral body greatly, fully saved handle grip position volume inside so that the setting of some other mechanism, and need not as prior art, to increase the volume of handle integral body, so make the people when holding operation, can feel more comfortable and convenient.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described:

Fig. 1 is the section of structure of a kind of specific embodiment of the utility model;

Fig. 2 is the stereochemical structure cutaway view of handle and switching mechanism thereof among Fig. 1.

Wherein: 1, tool body; 2, motor; 3, handle; A, holding area; 301, trigger muscle; 302, spring base; 4, switch; 401, contact; 5, trigger; 6, pivot; 7, container cavity; 8, alignment pin; 9, elastic component; 10, work package.

The specific embodiment

Embodiment: in conjunction with Fig. 1, Figure 2 shows that a kind of specific embodiment of the utility model hand held electric tool, it is a kind of shrub and hedge trimmer, the work package 10 that comprises tool body 1, is located in the tool body 1 motor 2, is connected on the tool body 1 and driven by motor 2, takes shape in the handle 3 on the tool body 1 and is located at bat-handle switch mechanism on this handle 3 holding area A; Described work package 10 is the tool sections that radially extend.

The mechanism of bat-handle switch described in the present embodiment is made of switch 4, trigger 5, pivot 6, alignment pin 8 and elastic component 9.Described trigger 5 is connected on the handle 3 by pivot 6, and these trigger 5 parts snap in the cavity of A inside, handle 3 holding area.Described switch 4 is fixed on the trigger 5 by alignment pin 8, and is absorbed in the container cavity 7 of being located on the trigger 5; This switch 4 is electrically connected with motor 2, is used to control the break-make of motor 2 circuit, has contact 401 on the switch 4, and forms in the described handle 3 holding area A with the relative triggering muscle 301 in contact 401.Described elastic component 9 is a back-moving spring, and an end of this back-moving spring is against on the spring base 302 that is formed in the handle 3 holding area A, and the other end then is against on the trigger 5, is convenient to resetting after trigger 5 activities.

The described this hand held electric tool of present embodiment, it is when operation, staff is held on the handle 3 holding area A, drive switch 4 activities by clinching trigger 5, connect motor 2 circuit behind the triggering muscle 301 in handle 3 holding area A are touched in the contact on the switch 4 401, make the electric tool operate as normal.And behind staff releasing trigger 5, trigger 5 resets under the elastic force effect of elastic component 9, thereby triggering muscle 301 cut-out motors 2 circuit are left in the contact 401 on the switch 4, quit work.

The described this hand held electric tool of present embodiment, because the switch in the bat-handle switch mechanism 4 is set directly on the trigger 5, simplified the structure of bat-handle switch mechanism integral body greatly, handle 3 holding area A volume inside have fully been saved so that the setting of some other mechanism, and need not as prior art, to increase the volume of handle 3 integral body, so make the people when holding operation, can feel more comfortable and convenient.
