Abstract
The utility model discloses a cutter blade. The cutter blade is provided with an axis which is outstretched longitudinally and is particularly used for rotary type operation. The rotating center of the cutter blade is provided with a mounting hole, and the cutter blade is provided with a double-tooth surface, i.e. arc tooth surfaces are distributed symmetrically along the axis of the cutter blade, and a plurality of saw teeth and backlashes with cutting slotting shaped edges are arranged alternately and successively on the tooth surfaces. When the cutter blade is used, the mounting direction is not needed to be noticed, and the tooth surface of the blade is ensured to be cut into the ground firstly. By adopting the blades with a double-tooth surface structure, the cutter blade has light weight and low loss to the current. The double-tooth surface can be replaced for use, and the using efficiency is high and the cost is low.
Description
Technical field
The utility model relates to a kind of blade, belongs to garden instrument.
Background technology
Trimmer is a outdoor garden instrument, mainly makes neat in edge by blade outstanding weeds on the cutting lawns limit that rotatablely moves of perpendicular, perhaps cuts out the groove of gardening moulding etc.The blade of common single cog is installed inconvenient, and is careless slightly, and the installation direction dress is wrong, and when start was used, blade does not have the one side of tooth at first to cut ground, and was stuck easily, causes electric current to rise, the cutting difficulty, and motor damages easily.And blade is owing to use single cog, after the wearing and tearing of blade single cog, and the blade that need more renew, service efficiency is low, the cost height.
The utility model content
The technical problems to be solved in the utility model is: provide a kind of can be easy for installation, the blade that service efficiency is high.
In order to overcome the defective that exists in the background technology, the technical scheme that its technical problem that solves the utility model adopts is: a kind of blade, blade axis with a longitudinal extension, be particularly useful for rotary operation, the pivot of this blade has installing hole, described blade has the bidentate face, and promptly described blade is distributed with the circular arc flank of tooth along the axis bilateral symmetry, has a plurality of sawtooth and the plurality of teeth voids that are provided with slotting tool shape sword in succession alternately on the flank of tooth.
According to another embodiment of the present utility model, blade comprises that further described sawtooth and described backlash are rounded down.
According to another embodiment of the present utility model, blade comprises that further described blade is " I " type.
According to another embodiment of the present utility model, blade comprises that further described blade adopts perhardened steel to make, and handle through blackout on the surface.
According to another embodiment of the present utility model, blade comprises that further described blade is used for trimmer.
The utility model has solved the defective that exists in the background technology, uses the utility model user not have the installation direction of noting, guarantees that the flank of tooth of blade is cut ground earlier.Since adopt the blade of bidentate face structure, in light weight, and blade is little to the loss of electric current.The bidentate face can be changed use, the service efficiency height, and cost is low.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the structural representation of preferred embodiment of the present utility model;
Fig. 2 is the structural representation of blade.
Wherein: 1, blade, 3, axis, 5, installing hole, 7, the flank of tooth, 9, sawtooth, 11, backlash, 15, the saw lid, 17, output shaft.
Embodiment
With preferred embodiment the utility model is described in further detail in conjunction with the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Trimmer shown in Fig. 1-2 comprises blade 1, drives the motor (not shown) that blade 1 rotates, and has the saw lid 15 that the part of being used for is held blade 1, and the output shaft 17 of motor is connected with blade 1.Wherein, blade 1 has the blade axis 3 of a longitudinal extension, be particularly useful for rotary operation, the pivot of this blade 1 has installing hole 5, described blade 1 has the bidentate face, be that described blade 1 is distributed with the circular arc flank of tooth 7 along axis 3 bilateral symmetry, have a plurality of sawtooth 9 that are provided with slotting tool shape sword in succession and plurality of teeth voids 11 alternately on the flank of tooth 7.Sawtooth 9 is rounded down with described backlash 11.Blade 1 is " I " type.Blade 1 employing perhardened steel is made, and surface process blackout processing, and like this, will be improved greatly the service life of blade 1.
When double cog blade 1 is installed, because blade 1 has the bidentate face, no matter the user carries out the still anti-dress blade 1 of formal dress blade 1 for the first time, can not impact during use trimmer, after the flank of tooth 7 wearing and tearing of a direction, blade 1 is pulled down from output shaft 17, then will saw the flank of tooth 7 of changing another direction after 1 upset and be re-installed on the output shaft 17, the sharp flank of tooth 7 can be proceeded deburring work, and is greatly convenient for users to use.
With above-mentioned foundation desirable embodiment of the present utility model is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this utility model technological thought.The technical scope of this utility model is not limited to the content on the specification, must determine its technical scope according to the claim scope.
