The utility model discloses a kind of mower motor with blade counnter attack mounting structure, comprise engine, engine spindle is connected with tool rest by flat key, the tool rest blade that is connected, tool rest comprises cylindrical tube, cylindrical tube bottom is provided with brace, and brace is provided with two arc boss that oppositely arrange, and arc boss is connected and is located at two through holes on blade; Described blade comprises blade body, and blade body two ends are provided with the horizontal knife face connecting by the inclined-plane that is inclined upwardly, and two reverse sides of horizontal knife face are provided with downward-sloping blade.The utility model coordinates two through-hole structures on blade by two arc boss that oppositely arrange on brace, prevent the anti-incised wound human body accident causing of installing of blade, and by blade two sides oppositely downward edge structure to make blade be down-cutting when the cutting, improved safety in utilization.
Description
Technical field
The utility model relates to a kind of mower motor, specifically a kind of mower motor with blade counnter attack mounting structure.
Background technology
General mower motor is mainly used in driving mower to advance and rotary mower blade uses.Traditional mower blade mounting means is all installed blade in related accessory such as 2 points of tool rest upper punch and blade and clamping screws, but this mode that is fixedly connected with exists that mower blade is anti-loaded causes hurting the problems such as human body, is difficult to reach mower job requirement.How preventing that mower blade is counter installs, increase mower service life, to improve job requirement be the object that those skilled in the art study always.
Utility model content
The utility model provides the mower motor with blade counnter attack mounting structure of a kind of simple in structure, stable connection, use safety.
A kind of mower motor with blade counnter attack mounting structure, comprise engine, engine spindle is connected with tool rest by flat key, the tool rest blade that is connected, described tool rest comprises cylindrical tube, cylindrical tube bottom is provided with brace, brace is provided with two arc boss that oppositely arrange, arc boss is connected and is located at two through holes on blade, coordinate two through-hole structures on blade by two arc boss that oppositely arrange, guarantee unique installation site of blade, prevented the casualty accident that the anti-dress of blade causes.The radian of described arc boss is greater than 180 degree, and the contact area improving between arc boss and through hole prevents breaking.Described blade comprises blade body, blade body two ends are provided with the horizontal knife face connecting by the inclined-plane that is inclined upwardly, two reverse sides of horizontal knife face are provided with downward-sloping blade, make blade by the reverse downward edge structure in both sides is down-cutting in the time cutting, and has improved safety in utilization.
Described engine spindle center is provided with screw, the clamping screw that periphery is socketed tool rest cushion cover, tool rest, blade, bolt dottle pin, the butterfly pad successively screw that is threaded.Tool rest cushion cover, tool rest, blade, bolt dottle pin, the butterfly pad of between clamping screw and screw, locking, this combining structure is not only overall locking, and tool rest cushion cover effectively avoided electric machine main shaft and tool rest to contact the wearing and tearing that cause between directly, greatly extend the service life of tool rest and blade.Butterfly pad is located at and between bolt dottle pin and bolt end, is utilized the predeformation structure of butterfly pad to prevent that bolt is along with faults such as getting loose appear in electric machine rotation.
The utility model is by coordinating two through-hole structures on blade by two arc boss that oppositely arrange on brace, prevent the anti-incised wound human body accident causing of installing of blade, and by blade two sides oppositely downward edge structure to make blade be down-cutting when the cutting, improved safety in utilization.
