Background technology:

People are when using electric shrub and hedge trimmer work, often need different posture of conversion and position with better pollard, electric shrub and hedge trimmer in the past, its handle and fuselage are fixed together, handle just can not be adjusted according to operator's work habit and different gestures and position, has increased operator's working strength.

In order to address the above problem, people have invented a kind of electric shrub and hedge trimmer of rotatable handgrip, as Chinese patent 200410064903.2 disclosed a kind of electric shrub and hedge trimmers, its handle is installed on the casing by annular sunk key is rotatable, the handle upper end is provided with chute, push button, spring, push button can slide in chute, spring one end is connected with push button, the other end is connected with handle, there are some lock slots at the position that contacts with handle on the casing, push button inserts lock slots under the effect of spring force, and at this moment, handle is fixed; In the time of need unclamping, push push button and dialling backward with thumb, make push button compression spring and break away from lock slots to cooperate, at this moment, handle is rotatable.Simultaneously, for fear of the danger that maloperation when rotated brings to the operator, motor driven switch and push button on the handle are designed to interlocking structure.Adjust handle and have the safety interlock structure though this electric shrub and hedge trimmer can rotate, also have following deficiency:

The first, in this structure, the adjustment of push button need rely on the muscle of thumb to finish, when push button was dialled backward, owing to need the compression spring, the pulling push button just needed certain strength, so make operate comparison difficulty and thumb skid easily, in addition, because the upper end that the chute of push button is arranged on handle is installed, its edge exposes, sharper, after thumb skids, can hit immediately on the edge of runner rear end, muscle on the incised wound thumb uses dangerous easily.

Summary of the invention:

The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of electric shrub and hedge trimmer simple to operate, safe in utilization is provided.

A kind of electric shrub and hedge trimmer that provides according to the utility model, comprise housing, motor, lopping shears and handle, motor is installed in the housing, lopping shears is installed in the housing front end and by motor-driven, the rotatable housing rear end that is installed in of handle, the driving switch of control motor break-make and the rotation pull-button of joystick rotation are installed on the handle, this driving switch and the interlocking of rotation pull-button, described rotation pull-button is by being arranged on the downside that chute on the handle is installed in driving switch, is provided with a back-moving spring between itself and the handle.

The utility model also has following technical characterictic:

Described rotation pull-button comprises handle and the draw runner that is provided with the affixed pair of parallel of shaking hands, handle exposes to handle, two draw runners slidably are installed in the described chute, wherein, lean on the outside of the draw runner of driving switch one side to be provided with first hook, another draw runner outside is provided with a stop block, and two draw runners are inboard to be connected with a contiguous block by its terminal position, this contiguous block inboard is provided with a projection, is placed in back-moving spring one end in this projection.

Described driving switch lower surface be extended with downwards one can cooperate with first hook second link up with, on the housing its with circumference that handle contacts on be provided with the lock slots that some and described stop block cooperates.

Described first, second hook all is " L " type, and wherein, first hook is squeezed and is installed on the draw runner.

According to a kind of electric shrub and hedge trimmer that the utility model provides, prior art has following advantage relatively:

In the utility model, the rotation pull-button is opened the downside that chute in handle is installed in driving switch by one, and its handle exposes to handle, during operation, only need to pull back handle, just can draw back the rotation pull-button very easily with forefinger and/or middle finger, make handle rotatable, it is very convenient to operate, and simultaneously, uses pull handle arrangement, finger can not skid, chute is set in the handle, can not incised wound point, and uses safety very.

Description of drawings:

Introduce the utility model in detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the structure for amplifying schematic diagram of I among Fig. 1.

Embodiment:

See figures.1.and.2, a kind of electric shrub and hedge trimmer that provides according to the utility model, comprise housing 1, motor 2, lopping shears 3 and handle 4, motor 2 is installed in the housing 1, lopping shears 3 is installed in housing 1 front end and is driven by motor 2, handle 4 rotatable housing 1 rear ends that are installed in, the driving switch 5 of control motor 2 break-makes and the rotation pull-button 6 of joystick 4 rotations are installed on the handle 4, this driving switch 5 and 6 interlockings of rotation pull-button, can not starter motor 2 when guaranteeing handle 4 rotations, can not rotary handle 4 behind the starter motor 2, can effectively avoid the operator because of danger that maloperation brought, rotation pull-button 6 is by being arranged on the downside that chute 41 on the handle 4 is installed in driving switch 5, can directly use the forefinger and/or the middle finger of the hand of the handle 4 of holding with a firm grip to spur this rotation pull-button 6, realize the rotatable of handle 4, operate easily, be provided with a back-moving spring 42 between rotation pull-button 6 and the handle 4, be used to rotate automatically reseting of pull-button 6.

Rotation pull-button 6 comprises handle 61 and the draw runner 62 that is provided with handle 61 affixed pair of parallel, handle 61 exposes to handle 4, this handle 61 can be made with soft material, or at its outside parcel one deck soft material, make finger energy when pulling pleasant, do not hinder hand, two draw runners 62 slidably are installed in the chute 41, wherein, lean on the outside of the draw runner 62 of driving switch 5 one sides to be provided with first hook 63, another draw runner 62 outsides are provided with a stop block 65, two draw runners, 62 inboard its terminal positions that lean on are connected with a contiguous block 66, these contiguous block 66 inboards are provided with a projection 67, are placed in back-moving spring 42 1 ends in this projection 67, and driving switch 5 lower surfaces are extended with second hook 53 that can cooperate with first hook 63 downwards, on the housing 1 its with circumference that handle 4 contacts on be provided with some lock slots 15 that cooperate with stop block 65, first,

second hook
