Abstract

A novel electric pruning shear includes a mainframe, a front handle, a back handle and a cutter; the mainframe includes a housing, a motor arranged in the housing and a braking device; the front handle and the back handle are respectively arranged at the front and the back ends of the housing; the cutter is arranged at the front end of the housing and is driven by the motor; the braking device consists of an interlocks and a brake lever which is controlled by the interlocks and can move up and down; the front and the back handles are respectively provided with a front switch and a back switch; a microswitch is mounted on the upper end of the brake lever in the housing; the front switch and the back switch are connected with the interlocks through flexible elements; when the front switch and the back switch are closed, the brake lever moves upwards, pushes against and opens the microswitch. The novel electric pruning shear is not only safe to use, but also has low cost.

Description

A kind of electric shrub and hedge trimmer

Technical field:

The utility model relates to a kind of garden instrument, particularly a kind of electric shrub and hedge trimmer.

Background technology:

Electric shrub and hedge trimmer in the past, the injury that the operator is brought for fear of error starting, people are provided with switch and make its interlock on the handle of front and back, must before and after switch on the handle all closed, motor could start, concrete structure is: in front hand grip and back handle place one microswitch is installed all, two microswitches are connected in series by lead, power supply must be through just being connected to motor behind two microswitches, on the handle of front and back, be provided with the start button that can start microswitch and expose to handle, people are the start button on the necessary hand control back handle when operation, start button on the another hand control front hand grip, like this, just effectively eliminated the operator and given harm own or that other people brought because of error starting.But this structure still exists some shortcomings, is specially:

The first, this inside configuration, the lead that connects each microswitch is long, is fixed up cumbersome and easily loosening, and rupturing because of touching moving component easily in the loosening back of lead, causes shutdown or leak electricity, and uses dangerous;

The second, this structure must increase the cost of complete machine with two switches.

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 safe in utilization, with low cost are provided.

A kind of electric shrub and hedge trimmer that provide according to the utility model, comprise main frame, front hand grip, back handle, shear, main frame comprises housing, be located at the motor in the housing, the brake stop device, before, back handle is located at the front and back end of housing respectively, shear is located at the housing front end and by motor-driven, the brake stop device is controlled brake lever moving up and down by a linkage and by this linkage and is formed, before, before being separately installed with on the back handle, back switch, in the brake lever upper end one microswitch is installed in the housing, before, back switch all is connected with linkage by flexible member, current, when back switch is all closed, moves on the brake lever and replace and open microswitch.

The utility model also has following technical characterictic:

Described flexible member is cable wire or brake cable.

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

The first, this structure has only been installed a microswitch at the brake lever upside, and the lead that connects between itself and the motor is very short, thereby, relatively good fixing, be not easy to become flexible, the probability end very damaged, appear in lead, uses as safe as a house.

The second, this structure has only been used a microswitch, its complete machine cost has been descended, thereby cost is cheaper.

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 provide according to the utility model, comprise main frame 1, front hand grip 2, back handle 3, shear 4, main frame 1 comprises housing 5, be located at the motor 6 in the housing 5, brake stop device 7, this brake stop device 7 is between motor 6 and back handle 3, before,

back handle

2,3 are located at the front and back end of housing 5 respectively, shear 4 is located at housing 5 front ends and is driven by motor 6, brake stop device 7 is made up of the brake lever moving up and down 72 of these linkage 71 controls a linkage 71 and, before, back handle 2, before being separately installed with on 3,

back switch

21,31, in brake lever 72 upper ends one microswitch 9 is installed in the housing 5, before,

back switch

21,31 all are connected with linkage 71 by flexible member 10, to control this linkage 71, this flexible member 10 can be cable wire or brake cable, current,

back switch

21,31 when all closed, flexible member 10 pulling linkages 71, linkage 71 is controlled simultaneously to move on the brake lever 72 and is replaced and open microswitch 9, motor 6 energisings, this electric shrub and hedge trimmer enters duty, only preceding,

back switch

21,31 when all closed, moves height on the brake lever 72 and could start microswitch 9.

The foregoing description is only for the usefulness that the utility model is described; and be not to restriction of the present utility model; the those of ordinary skill in relevant technologies field; under the situation that does not break away from spirit and scope of the present utility model; can also make various variations and modification; therefore all technical schemes that are equal to also belong to category of the present utility model, and scope of patent protection of the present utility model should be limited by each claim.
