Dental handpiece, according to the difference of its clamping trolley pin mode, can be divided into purl formula dental handpiece and pressing type dental handpiece, and car pin is locked on dental handpiece by purl device by purl formula dental handpiece; Pressing type dental handpiece is by pressing its bonnet to lock or taking off car pin.Dental handpiece is made up of mobile phone handle and head usually, and wherein head comprises the parts such as handpiece case, movement and bonnet.Existing pressing type dental handpiece bonnet is made up of bonnet button, spring, bonnet supporter top and bonnet supporter bottom, during the production and assembly of bonnet, first the bottom of bonnet button from bonnet supporter top is passed, both are connected together, then the bottom of spring from bonnet supporter top is passed, with bonnet button immediately preceding together with, finally the bottom of bonnet supporter is tightened to the top of bonnet supporter by the mode of screw thread, spring and button are fixed on bonnet supporter.The mode operation of this assembling bonnet is many, and troublesome poeration, production efficiency is low.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of pressing type dental handpiece optimizing rear cover structure, and the assembling mode operation solving existing bonnet is many, troublesome poeration, the problem that production efficiency is low.
The technical scheme that the present invention solves the problems of the technologies described above is as follows, a kind of pressing type dental handpiece optimizing rear cover structure, comprise mobile phone handle and head, described head comprises handpiece case, movement and bonnet, it is characterized in that: described bonnet is made up of bonnet button, spring and bonnet supporter; Described spring is located between described bonnet button and bonnet supporter; Described bonnet button is connected by snap-in structure with described bonnet supporter.
Further, described snap-in structure comprises groove and can buckle into multiple back-offs of described groove; Described groove is located on described bonnet supporter; Described back-off is located on described bonnet button.
Further, described groove is located at the inside of described bonnet supporter near one end of described bonnet button; Described back-off is located at described bonnet button one end near described bonnet supporter.
Further, described back-off is unidirectional hook structure.
The beneficial effect of above-mentioned further scheme is: back-off is unidirectional hook structure, cannot take out after making it buckle into groove again.
Further, described back-off has three, and three described back-offs evenly and be symmetricly set on described bonnet button.
The beneficial effect of above-mentioned further scheme is: be arranged so that back-off uniform force symmetrically, long service life, and three tip upside down on to meet and use minimizing back-off quantity while needs and saved manufacturing cost.
Further, described groove is an annular groove.
Further, described groove is multiple grooves being in conplane arc, and the quantity of described groove is no less than the quantity of described back-off, and the position of described groove is corresponding with the position of described back-off.
The invention has the beneficial effects as follows: connect bonnet button and bonnet supporter by this snap-in structure connected mode of multiple back-off fastening being fixed in a groove, make the assembling of bonnet more convenient, simultaneously owing to decreasing parts, make the yield rate of production and processing higher, the reliability of product is also higher.
Further, the outside of described bonnet supporter is provided with the screw thread be connected with described handpiece case.
The beneficial effect of above-mentioned further scheme is: be threaded connection and make the structure of dental handpiece compacter, also bonnet for convenience detach.
