Abstract

The utility model discloses an electric sharpener, consisting of a casing. A motor and a power supply are arranged in the casing, an abrasion wheel is connected on the motor axle of the motor, the motor axle of the motor is connected with the abrasion wheel in a transmission way through an elastic connecting device, the elastic connecting device is comprised of a spring holder fixedly connected with the motor axle of the motor, an elastic sleeve fixedly connected with the abrasion wheel and suited on the spring holder, and the spring supported between the spring holder and the elastic sleeve. A sleeve-shaped angle stabilization device suited outside the abrasion wheel is fixed on the electric sharpener, the sleeve wall circumference is provided with at least a feed trough, and the feed trough inclines to the bottom surface of the angle stabilization device and extends to the abrasion wheel. When the utility model works, the feed trough of the angle stabilization device can maintain the direction of feed of the cutter edge, and the elastic connecting device can push the abrasion wheel to be tightly fitted on the cutting edge of the cutter, thereby guaranteeing that the ground cutting edge angle is consistent.

Description

Electric knife sharpener

Technical field

The utility model relates to knife sharpening device, especially a kind of electric knife sharpener.

Background technology

Present electric knife sharpener generally adopts double abrasive wheel, utilize the gap of two emery wheels of rotation to grind the moving knife sword back and forth, two emery wheels of this knife sharpener are difficult to assurance speed unanimity, and the abrasion of grinding wheel post gap changes wayward sharpening angle, cause when whetting a knife, can not keeping blade angle, might scrap the cutter mill.

The utility model content

The electric knife sharpener that can keep blade angle when the purpose of this utility model is a kind of the sharpening is provided constantly.

The technical solution of the utility model is: a kind of electric knife sharpener, comprise shell, be provided with motor and power supply in the shell, be connected with emery wheel on the motor shaft of motor, the motor shaft of described motor is in transmission connection by an elastic connecting device and emery wheel, this elastic connecting device is the spring base of fixedlying connected by with the motor shaft of motor, what fixedly connected with emery wheel is sleeved on resilient sleeve on the spring base, the spring that is supported between spring base and the resilient sleeve constitutes, be fixed with the angle stabilising arrangement of the shell-like that is sleeved on the emery wheel periphery on the electric knife sharpener, have at least one feed groove on the jacket wall circumference of this angle stabilising arrangement, this feed groove is to the inclination of the bottom surface of angle stabilising arrangement and extend to the emery wheel place.

The central authorities of the spring base of described elastic connecting device are provided with vertical back shaft, the spring base outside is arranged with bracing ring, the motor shaft that back shaft is provided with the endoporus power supply machine inserts also fixedly connected, the bottom surface of resilient sleeve is provided with the adapter sleeve that can be sleeved on the back shaft, spring housing is contained on the adapter sleeve, the resilient sleeve outside is arranged with the clamping ring on the bracing ring that can be sleeved on spring base, but the bottom of clamping ring is provided with the hook of spiral-lock on bracing ring.

Described emery wheel is that working face is the inclined-plane emery wheel on inclined-plane.

The top of described shell is provided with motor fixing plate, and motor is fixed on the bottom surface of motor fixing plate, and the angle stabilising arrangement is fixed on the end face of motor fixing plate.

The bottom of described shell is provided with battery cover, and the power supply in the shell is the battery that is installed between motor fixing plate and the battery cover, and the sidewall of shell is provided with press button, and battery constitutes power circuit by electric wire and press button, motor joining.

The utility model is when work, the feed groove of angle stabilising arrangement can keep the direction of feed of blade, but elastic connecting device pushing tow emery wheel is adjacent to the cutting edge of cutter, thereby the blade angle unanimity that assurance grinds, this uses novel easy and simple to handle, laborsaving, safety, and only cutter need be dragged twice on knife sharpener just can finish sharpening.
