Description

Detent mechanism

Technical field

The present invention is about the detent mechanism of a kind of detent mechanism, particularly a kind of pointer.

Background technology

Present making rapid progress of science and technology, the speed progress that semiconductor technology promptly doubles with open ended transistor size on per 18 months its circuit, its performance also doubles.Therefore, also more and more little at electronic product towards volume, but functional more and more strong direction is developing.

Under light, thin, short, the little trend of electronic product, all only possess usually the most basic keyboard is arranged, or even need external connection keyboard that the function of instruction input just can be provided.If the user wants on less operation interface, assign and the same in the past instruction its handling comparatively difficulty that just becomes.Therefore, manufacturer develops the instruction that simplifies the operation of method with touch successively.Now, in consumption electronic products, exist the application of many touch panels.

Yet, if directly remove Touch Screen, can have oiliness because of finger, and on screen, stay fingerprint with finger, cause screen-picture comparatively fuzzy.And on undersized panel, if, cause operational erroneous judgement property easily directly with the finger touch panel.Therefore, on undersized panel, be to adopt pointer to operate mostly.

At present, the reception position of pointer is the back side or the side at electronic product mostly.When the user needs, take out again and use.And the method that known pointer is taken in, major part all is directly pointer to be inserted accommodating groove, and is little than pointer through the caliber of accommodating groove front end, to block pointer, makes pointer be unlikely to drop.The mode that the user takes out is the ridge of the pointer tail end that directly press...withes one's finger, and the application of force is ticked pointer again.But with pointing the mode that catches on pointer and take out, user's Overexertion takes place easily, and cause pointer directly to fly out.This measure lets surface wear and the scratch on ground of the pointer tip of the brushstyle of a writing or painting easily, when the user is used in the contact panel operation with pointer again, causes the contact panel surface by scratch equally.Even pointer vanishes from sight after flying out, and the user can only go to buy a new pointer again and substitute.

The method that other has known pointer to take in is taken out pointer for the mode that adopts elastic force.When the user will take in, pointer is pressed into the passing element in the storage tank, the front end clasp of pointer is by one section metal wire rod clamping with bending and molding, the element institute buckle and pointer tail end clasp is reset makes pointer be positioned storage tank.When the user will take out; The application of force makes itself and tail end clasp break away from the relation of buckle at reposition element, passes element generation elastic-restoring force and make, and oppositely pointer is ejected outside the storage tank; But pointer is still by the metal wire rod clamping, and the user applies external force again pointer is detached.Yet this mode has following problem, when user's application of force is pressed into the passing element with pointer; Excessively the application of force makes the pointer tip of the brushstyle of a writing or painting push up the storage tank inwall and damages easily; And metal wire rod also easily because of the long-term elasticity variation of using, can't be combined closely with the tip of the brushstyle of a writing or painting clasp during clamping pointer, when the pointer At time of eject; The problem that can occur getting loose phenomenon and cause excessive the ejection to storage tank, user need pick up pointer voluntarily exists.

Summary of the invention

Pointer commonly used can produce the problem that pointer ejects accommodating groove when taking out, like the mode of ticking with finger, cause the pointer storage tank that directly flies out easily because of the application of force is improper.With the method for elastic force, the tip of the brushstyle of a writing or painting of pointer easily supports and causes damage in the top mutually with storage tank, and metal wire rod is long-term can to produce elastic fatigue after using, and when pointer receives elastic force and ejects storage tank, pointer also can take place directly eject the situation outside the storage tank.In view of above problem, the present invention provides a kind of to have the protection pointer tip of the brushstyle of a writing or painting and prevents that pointer from excessively ejecting the detent mechanism of accommodating groove.

Detent mechanism disclosed according to the present invention is applied to accommodating touch-control pen, and these pointer two ends have one first clasp and one second clasp, and it includes storage tank, pushing part and clamping piece.Storage tank has an arrival end and and inserts and puts end, and this pointer is inserted in this storage tank by this arrival end, and has the ready position that the favorite places and of taking in this storage tank breaks away from this arrival end one distance.The pushing part is arranged at this arrival end place through one first elastic component movably to concern.Be positioned at this favorite places in this pointer, this pushing part is suitable for buckle or breaks away from this first clasp.Clamping piece is arranged on this and inserts and puts the end place with relation movably through one second elastic component.Clamping piece also has a fastener arm, and the fastener arm is snapped in this second clasp, is moved to this ready position to limit this pointer by this favorite places.

Detent mechanism disclosed according to the present invention; After wherein first elastic component is compressed; Be the state that breaks away from buckle between pushing part and the pointer, pointer just receives the passing strength that second elastic component produces, together with the clamping piece segment distance that in storage tank, slides; But pointer is still grasped by clamping piece, and this distance can be limited by the displacement interferometer that clamping piece and storage tank produce mutually.So, can prevent effectively promptly that pointer from excessively ejecting storage tank and the problem that need pick up or lose, significantly increase user's convenience, and the tip of the brushstyle of a writing or painting through pen cap protection pointer, its damage prevented.
