The outside of described two expansion pieces is supported with elastic component respectively.This spring combines two expansion pieces under normal condition, during charging back indentation pin, again two expansion pieces are suppressed together with its elastic force.
Described pedestal is provided with the slit and fills up structure.Under charged state,, be in the good insulation performance state with effective maintenance pin in order to fill up the slit that comprises pin holes between the two expansion pieces.
Described expansion piece is provided with guide frame, so that when stretching out pin, makes two expansion pieces according to default direction expansion.
The present invention is by embracing two expansion piece bullets on pin, and a pushing structure of moving with pin is set, two expansion agllutinations lump together under the normal condition, pin is positioned at the shaver housing, in a single day pin is pushed out during charging, the two is promptly expanded to both sides under the promotion of pushing structure, thereby it is idle that shaver is in, when normal non-charged state such as using, keep its little and attractive in appearance overall dimension, the thin shell that the shaver shell is had be subjected to the user to favor, and under shaver charges the transition condition of operation, just when pin stretches out, just allow the shell structure physical dimension that relates to the charging plug part enlarge, make it satisfy the corresponding national standards requirement, with the safety of guaranteeing that the shaver user charges and uses.
The present invention be advantageous in that:
1, in the slimming of market demand popular welcome electric shaver profile, ultrathin typeization, and wish that shaver carries under the situation of chargeable plug simultaneously, adopt the charging plug of the present invention's exploitation, can be under the prerequisite that does not increase shaver profile gauge, solve present rechargeable slim, ultrathin shaver because of charging plug physical dimension deficiency, can not satisfy the concerned countries standard-required, have the problem of charging operation hidden danger.
2, adopt the charging plug of the present invention's exploitation, can make slim, ultrathin shaver be more convenient for portably using, for client offers convenience.
3, ingenious, the compact in design, easy and simple to handle, safe in utilization of charging plug structure that adopts the present invention to design and develop can improve the scientific and technological content and the product specification of shaver product simultaneously, thereby obtain bigger economic benefit.
Below in conjunction with Figure of description the present invention is described in detail.
