The utility model solves the technical scheme that its technical problem adopts, it comprises body, back handle, head capsule, protecgulum, head capsule is fixed on casing, protecgulum is fixed on head capsule, the armature spindle of described body is arranged on head capsule rotationally, head capsule is provided with rotating power transmission shaft, rotating output shaft is installed between head capsule and protecgulum, power transmission shaft is vertical with armature spindle to be arranged, output shaft and power transmission shaft be arranged in parallel, armature spindle is fixed with one-level driving gear, power transmission shaft is fixed with one-level driven gear, power transmission shaft is provided with secondary active gear shaft, output shaft is fixed with secondary driven gear, one-level driving gear engages with one-level driven gear, secondary active gear shaft engages with secondary driven gear.
The further scheme of the utility model, described back handle can be arranged on body each 90-degree rotation in left and right, and back handle is provided with the spin locking button coordinated with body.
The further scheme of the utility model, the output of described output shaft is fixed with cutting blade by clip plate and outer plate, protecgulum by protective cover anchor ear be provided with can rapid adjustment protection angle cutting blade protective cover.
The further scheme of the utility model, described one-level driving gear and one-level driven gear angle are bored tooth and are engaged and form primary speed-down, and secondary active gear shaft engages with secondary driven gear helical teeth and forms double reduction.
The further scheme of the utility model, described armature spindle is arranged on head capsule by rotor front bearing, the two ends correspondence of driving cog axle is provided with the drive bearing be arranged on head capsule, and the two ends of output shaft correspondence is provided with the needle bearing that is arranged on head capsule and protecgulum and exports bearing.
The further scheme of the utility model, described head capsule is fixed with dismountable front hand grip.
After adopting said structure, the utility model has following advantage and effect: one is because armature spindle is slowed down and secondary helical teeth engagement deceleration by the engagement of one-level angle cone tooth, realize double reduction drive mechanism, substantially increase Driving Torque, polishing and cutting efficiency improve a lot.Two is that head capsule profile also diminishes thereupon, and the part that cutting blade exposes is relatively many, significantly can increase depth of cut because after employing double reduction, the outside dimension of secondary driven gear diminishes relatively.Three is because back handle can turn 90 degrees by left-right rotary, cutting blade protective cover rapid adjustment can protect angle by protective cover anchor ear, and make cutting operation protection more reliably, safely and smoothly, polishing and cutting function are changed simple and convenient, realize a tractor serves several purposes, the scope of application is wider.Four is that stable drive is reliable because Driving Torque is large, and work more flexibly and steadily, effectively reduces motor temperature rise, greatly extends the service life of product.
