Abstract

The present invention relates to a razor device of press key type electric shaver. It comprises blade and blade carrier, the blade is fixed on the blade carrier. It is characterized by that on the blade carrier a pin hole is set, the blade carrier can be movably fixed on the machine shell by means of pin shaft and in hole, on the pin shaft a torsion spring is mounted, one end of said torsion spring is supported on the blade carrier, and another end of said torsion spring is fixed on the machine shell, and on the machine shell a blade carrier locking mechanism is mounted, and the blade carrier locking mechanism comprises press-key, press-key seat and pressure spring. Said invention changes the operation mode of traditional razor, and its operation is flexible and its service life is long.

Description

Button electric razor handle of a knife knife system

Technical field

The present invention relates to a kind of electric shaver, especially the handle knife system of button electric shaver.

Background technology

At present the electric shaver that uses has the handle cutter of pruning temples mostly, and its handle knife system generally adopts driving, pushes away on referring to firmly with mother during use, and knife rest is released, and uses the handle cutter that is installed on the knife rest to carry out the pruning of the hair on the temples.This driving electric razor handle of a knife knife system uses relatively effort, and the time can produce misoperation, cause easy damage handle cutter member.

Summary of the invention

The invention provides a kind of handle knife system of button electric shaver, this handle knife system can make the handle cutter flexible operation of electric shaver, puts in place accurately, and member is not fragile, long service life.

For achieving the above object, the technical solution of the utility model is: a kind of handle knife system of button electric shaver, comprise blade and knife rest, blade is fixed on the knife rest, it is characterized in that: pin-and-hole is arranged on the knife rest, knife rest is fixed on the tool tip by bearing pin and pin-and-hole activity, and torsion spring is housed on the bearing pin, and torsion spring one end is supported on the knife rest, the torsion spring other end is fixed on the support, the knife rest locking mechanism is housed on the casing, and this knife rest locking mechanism comprises button, key base and stage clip, button are sleeved on the key base, stage clip is contained on the key base, key base can be moved to the left under the button effect, and knife rest is provided with snap close, and key base is provided with latch fitting.When knife rest is in when closing up state, latch fitting inserts snap close under the stage clip effect, pin knife rest; When button when moving left, latch fitting breaks away from snap close, knife rest ejects under the torsion spring effect.

The handle knife system of the electric shaver of this structure, as long as click the button that is contained on the casing limit gently, just can open the knife rest locking mechanism, knife rest ejects under the torsion spring effect, this device has changed the mode of operation of traditional handle cutter, has flexible operation, puts in place accurately, advantages such as member is not fragile, long service life.

The specific embodiment

As shown in drawings, the handle knife system of present embodiment button electric shaver, comprise blade (2) and knife rest (1), blade is fixed on the knife rest, pin-and-hole (11) is arranged on the knife rest (1), knife rest is fixed on the casing (12) by bearing pin (3) and pin-and-hole (11) activity, torsion spring (4) is housed on the bearing pin, torsion spring one end is supported on the knife rest, the torsion spring other end is fixed on the casing (12), knife rest relies on the torsion of torsion spring that knife rest is ejected by the bearing pin location, and by the parallel cutting of motor switching transmitting mechanism, casing is equipped with the knife rest locking mechanism on (12), this knife rest locking mechanism comprises button (7), key base (6) and stage clip (5), on the button suit key base, stage clip is contained on the key base, and the stage clip other end is fixed on the casing, key base can be moved to the left under button promotes, knife rest is provided with snap close (9), and key base is provided with latch fitting (8), and present embodiment latch fitting (8) is hook-shaped.When knife rest is in when closing up state, latch fitting (8) inserts snap close (9) down in stage clip (5) effect, and snap close can be lockhole or locked groove, and present embodiment adopts lockhole (10), with the working strength of raising snap close.When needs handle cutter is worked, make key base toward moving left by button, stage clip compresses, and latch fitting breaks away from snap close, and knife rest ejects under the torsion spring effect.When desiring to make the handle cutter to close up, only need knife rest is pressed, at this moment, latch fitting resets under the stage clip effect and inserts snap close knife rest is pinned.

Accompanying drawing provides the handle knife system that uses on the reciprocating electric razor, be a kind of specific embodiment of the present invention, the handle knife system of this button electric shaver equally also is applicable to the electric shaver such as all band handle knife systems such as reciprocating type, rotary, rollers.
