Title:
ENGAGEMENT STRUCTURE IN SHAVER HEAD
Document Type and Number:
WIPO Patent Application WO/2020/103113
Kind Code:
A1
Abstract:
An engagement structure in a shaver head is characterized in that: an installation recess (31) is formed at a connector base (3), and a side wall of the installation recess (31) is provided at least with two engagement recesses (32) corresponding to each other; an annular installation boss (41) is formed at a connector (4), and matches and is inserted into the installation recess (31), and installation holes (42) corresponding to the engagement recesses (32) are formed at a side wall of the annular installation boss (41); and a ball (5) is installed in each installation hole (42), and the connector is provided with an elastic member (6) capable of driving the ball (5) such that the ball (5) is partially exposed out of the installation hole (42) and engaged with the engagement recess (32). The advantage of the engagement structure lies in that the elastic member (6) and the ball (5) cooperate with each other, such that wear and tear can be reduced during the detachment of the shaver head by means of rolling and engaging the ball, thereby extending the service life, and making the detachment easier and more convenient.
