Summary of the invention
The objective of the invention is to overcome the defective that prior art exists, a kind of careless pruner of cutting is provided.
The technical scheme that realizes the object of the invention is: cut careless pruner, comprise main body and base plate cutting assembly, described main body comprises one with the casing of handle, described casing outer setting has the trigger of gauge tap break-make, be provided with rechargeable battery and a motor that is electrically connected by switch and rechargeable battery in the casing, motor output is through motor gear, idler gear, the gear wheel eccentric wheel is to the base plate cutting assembly, described base plate cutting assembly comprises base plate and cutter head assembly, described gear wheel eccentric wheel and Large Gear Shaft During be movable the installation axially, be provided with the back-moving spring that the gear wheel eccentric wheel is resetted in the described main body, settle an extension spring between described base plate and the cutter head assembly.
Further, the two ends of described extension spring are buckled on the stud of cutter head assembly, and middle spaced winding ring is fixed on the base plate.
Described back-moving spring is installed on the Large Gear Shaft During.
Two sides of described base plate are provided with buckle, and described casing base is provided with the draw-in groove corresponding with buckle.
Be provided with spacing push button on the casing of described main body rear end.
Described base plate is provided with hold-down screw.
The present invention has positive effect: the present invention is when allowing blade replacement more, blade to be forwarded to the top tool changing, very visual, blade is installed on the base plate first, and base plate is put into main body together, then utilize back-moving spring and extension spring, when machine turns, the eccentric eccentric wheel meeting of gear wheel Auto-mounting is installed very quick in the ring of eccentric wheel retaining ring, hand need not be run into blade and gets final product tool changing in the exchanging knives process, very safe, cleaning.
