Description

A kind of electric tool

Technical field

The utility model relates to a kind of hand-held lawn care instrument.

Background technology

At present, people are usually by increasing on mower that deburring wheel annex is realized not only can beating the grass but also can deburring, but the operator often is positioned at the direction operation moving head perpendicular to deburring, is unfavorable for the application of force.U.S. Pat 6516598 discloses a kind of electric cutting tool, by the drive mechanism of multidirectional rotation is set at the moving head head, the power supply that will be positioned at away from the first end of beating the grass is delivered to moving head, simultaneously between moving head and two operating grips, roller is set, be used to support entire tool beat the grass and deburring two states lower edge operator's direction of motion move, because the mower motor is positioned at the end away from moving head, the weight of whole motor and vibration all concentrate on the grip position, can be quite tired after the operator works long hours.European patent EP 1415524 discloses a kind of mower, a sheathed detachable roller with the coaxial setting of working head on the moving head housing, housing can rotate between position and the trim position beating the grass with respect to handle, when mower is beaten the grass line when being positioned at perpendicular, handle and handle assembly turn to perpendicular with respect to moving head, roller can move along operator's moving direction, because the installation site of roller on housing limit and can not be overlapped with the motor center of gravity because of structure, the vibration of motor can cause roller to turn round when beating the grass, the moving line instability.

Summary of the invention

For overcoming the above-mentioned defective of prior art, it is a kind of easy to use that the utility model provides, motion stabilization, two function mowers simple to operate.

The purpose of this utility model is achieved in that a kind of electric tool, comprise: the cutting tool that in first working face, rotates around first axle, be contained in the motor that links to each other with described cutting tool in the housing, and the handle assembly of the elongation that links to each other with housing, second axis runs through described handle assembly, described handle assembly can rotate with respect to described housing between the primary importance and the second place, when described handle assembly is positioned at primary importance, described second axis and first working face have a certain degree, when described handle assembly is positioned at the second place, described second axis is parallel with first working face, it is characterized in that: the axis of described roller is parallel haply with first axle but do not overlap; Described handle assembly comprises and can revolve the handle that turn 90 degrees around second axis; Also be provided with assist handle on the described handle assembly; Described handle assembly links to each other with housing by jockey, and described jockey comprises connector that links to each other with handle assembly and the matrix that links to each other with housing, and described connector can rotate around rotation with respect to described matrix; Described matrix extends axially certain distance along rotation and forms support arm, and described roller is arranged on the end of described support arm; Described matrix and housing can be one; When described handle assembly was positioned at the second place, the center of described second axis and roller was positioned at same plane haply; Described handle assembly comprises the connecting rod of handle and elongation, described connecting rod comprise link to each other with housing first end and second end that links to each other with handle.

Compared with prior art, the beneficial effects of the utility model are: by on housing, increasing the roller annex,, realize the simple conversion of mower and two kinds of functions of trimmer in conjunction with the handle assembly that rotates relative to housing, and easy to operate.

Embodiment

Referring to accompanying drawing 1～4, a kind of mower comprises working head 4, links to each other with working head 4 and can be with respect to the handle assembly 3 of working head 4 around rotation 18 rotation by jockey 5, and is arranged on assist handle 16 on the handle assembly 3.Wherein, working head 4 comprises and can be used to drive the motor 2 of cutting tool 1 around the cutting tool 1 of first axle 11 rotations, and the housing 6 that holds motor 2.Cutting tool 1 can be the flexibility line of beating the grass, and also can be plastics cutting blade or Metal Cutting sheet, can be around first axle 11 rotations in first working face 12.Operator's working head 4 that tramps with one's feet, apply the power angled to handle 8 with handle assembly axis 14, make handle assembly 3 that jockey 5 drives turn to horizontal level from the upright position with respect to working head 4, simultaneously the handle in the handle assembly 38 is rotated 90 ° around second axis 14, thereby, mower can be converted into trimmer, and housing 6 is provided with roller 10, and the operator can apply operating physical force along the direction of motion of trimmer.

Handle assembly 3 links to each other with housing 6 by jockey 5 and can rotate between a plurality of positions around rotation 18 with respect to housing 6.Handle assembly 3 comprises the connecting rod 19 of handle 8 and elongation, and first end 31 of described connecting rod 19 links to each other with housing 6, and second end 32 of connecting rod 19 links to each other with handle 8.When handle assembly 3 was positioned at primary importance, second axis 14 and first working face 12 had a certain degree.Under the duty of beating the grass, this angle is 30～60 degree normally, are suitable for the operator most firmly.This angle can reach 90 degree, and this moment, the operator can discharge both hands fully, and mower just can be uprightly on the ground under other external force effects not having.When handle assembly 3 is positioned at the second place, second axis 14 is parallel with first working face 12, this moment, the operator rotated 90 degree with handle 8 around second axis 14, made handle assembly 3, moving head 4 and deburring wheel 10 in the same plane substantially, mower can be hung on the wall.

Jockey 5 comprises the matrix 7 that takes the shape of the letter U and T-shaped connector 9.Matrix 7 arm wherein extends axially certain distance along rotation 18 and forms support arm 15, the axis 13 that is parallel to the roller of first axle 11 in the end of support arm 15 formation one, roller 10 is involuted by two halves, is fastened on the end of support arm 15 and rotates around the axis 13 of described roller by screw.Matrix 7 is set on the housing 6, and also can make with housing 6 is one.One end of connector 9 links to each other with handle assembly 3, and the other end links to each other with matrix 7 and can rotate in a plurality of positions around rotation 18 with respect to matrix 7.When handle assembly 3 turned to the second place, the center of roller 10 and second axis 14 were positioned at same plane substantially, and the operator can move along the direction that roller 10 rolls, and carries out deburring, motion stabilization.

When electric tool uses as mower, the handle assembly 3 and first working face 12 have a certain degree, the operator is holds handle 8 on the other hand, another hand grips assist handle 16, the edge needs the direction of finishing to move the moving head 4 of mower, and guard shield 17 can prevent that the residue after cutting tool 1 will be beaten the grass from getting rid of to the operator.When electric tool uses as trimmer, elder generation's swing handle assembly 3, make second axis 14 parallel with first working face 12, simultaneously around second axis, 14 swing handles 8, make handle assembly 3 that the operator sees and roller 10 roughly at grade, this moment, operator grasps handle 8 and assist handle 17 moved along the direction of deburring, and the rotating direction of roller 10 is identical with operator's moving direction, and flexible operation is laborsaving.
