One slider, its center through hole is passed through for axostylus axostyle, and the inboard props up extension member, and the corresponding flat bevel of periphery is provided with sliding surface, and the outside is provided with a sliding recess and two adjacent sliding protuberances;

One revolving part, its central open-work passes through for axostylus axostyle, and is buckled in catching groove with a cramp, revolving part is connected with axostylus axostyle, its inboard is provided with an end recess and adjacent two ends protuberance, dock with the sliding protuberance and the sliding recess formation of this slider, and periphery is provided with an interface:

Can two article that be connected to sleeve and revolving part be raise or cover by the relative action of extension member, slider and revolving part.

Wherein the flat bevel of this sleeve is for being oppositely arranged.

Wherein this interface is single, double face or the polygon cylinder of milling.

Wherein this extension member is a spring.

Wherein this open-work is a convex shape, and cramp is placed in the open-work.

Description of drawings

For further describing concrete technology contents of the present utility model, at first see also accompanying drawing, wherein:

Fig. 1 is the three-dimensional exploded view of the utility model rotating shaft;

Fig. 2 is the sectional drawing of the utility model group after upright;

Fig. 3 a and Fig. 3 b are the stereogram of the utility model two serviceability;

Fig. 4 is the stereogram of the utility model group after upright.

Embodiment

As shown in Figure 1, basically, rotating shaft of the present utility model is combined by a sleeve 1, one axostylus axostyle 2, one extension members, 3, one sliders 4 and a revolving part 5.

Wherein, sleeve 1 is a hollow cylinder, and a hole 11 is opened in the bottom, pass through for axostylus axostyle 2, hold nozzle 12 then to chat inserting of element after the confession in addition, sleeve 1 periphery forms a flat bevel 13 at least, as shown in the figure, this sleeve 1 periphery forms two flat bevels 13 relatively, in order to the axial slip of slider 4.In addition, flat bevel 13 latter ends form a junction, and with article, for example the body intercalation is fixed.Only this flat bevel 13 does not exceed with aforesaid embodiment, and it must be the polygon cylinder, also can obtain identical guiding and locating effect.

Axostylus axostyle 2 is a body of rod, each element that it is chatted after axially passing through, and bottom reel 21 then props up a hole 11, and the top then has a catching groove 22.

Extension member 3 is an elastomer, and for example spring after it passes through for axostylus axostyle 2, and is placed in the sleeve 1.

Slider 4 is a cylinder, and its inboard is resisted against extension member 3, and central authorities establish a through hole 41 and pass through for axostylus axostyle 2, and sliding surface 42 is established in the corresponding flat bevel of periphery 13 positions, to insert in the sleeve 1, makes whole the slider 4 can axial displacement sleeve 1 in, forms interactions with extension member 3.These slider 4 outsides are provided with a sliding recess 43 and two adjacent sliding protuberances 44, dock effect to form with revolving part 5.

Revolving part 5 also is a cylinder, its central authorities open a step shape open-work 51 pass through for axostylus axostyles 2 after, be buckled in catching groove 22 with a cramp 23, cramp 23 is placed in the open-work 51, to define whole shaft length.These revolving part 5 inboards are provided with an end recess 53 and adjacent two ends protuberance 52, to dock with the two sliding

protuberances

44 and 43 formation of sliding recess of slider 4.In addition, these revolving part 5 surfaces are provided with at least one interface 54, with another article, for example the lid intercalation is fixed, and is ditto described, this interface 54 can be the single, double binding locating effect that face or polygon cylinder all can obtain to expect that mills when implementing.

As Fig. 2 and shown in Figure 4, be sectional drawing and stereogram after the utility model group is stood.When operating as desire, see also Fig. 3 a, the sliding protuberance 44 of this slider 4 and sliding recess 43 form mated condition with the end recess 53 and the end protuberance 52 of revolving part 5 respectively, for example represent body and lid to be in the state of covering.As desire lid is raised,, made two ends protuberance 52 break away from sliding recesses 43 and, make slider 4 be subjected to the end thrust of revolving part 5, and make sliding surface 42 in flat bevel 13, move along the laterosurtrusion of two sliding protuberances 44 then by pulling open lid, and compression extension member 3.See also Fig. 3 b, only when end protuberance 52 is crossed the summit of sliding protuberance 44, then extension member 3 stretches, make slider 4 outer moving, and impel end protuberance 52 to move down along sliding protuberance 44 other sides, buckle into sliding recess 43 once again up to 52 times turnbacks of two ends protuberance, on behalf of lid, this promptly be the state of raising with respect to body.And lid is covered on body as desire, only need reverse operating to get final product.

Via enforcement of the present utility model, its movable end that improves axostylus axostyle really is with the processing difficulties of rivet clasp in the revolving part outside, and both are in conjunction with not good disappearance.In addition, via the relative action of extension member, a slider and a revolving part, make the lid function that tool is raised automatically and covered in a certain angle.Moreover, can combine the location with body and lid apace by the flat bevel of sleeve and the interface setting of revolving part, exempt screwing togather operation.Into person is arranged especially, assembling rapid and convenient of the present utility model, and the requirement of not losing its precision really is a big good structure of ware.

The utility model discloses, and is a kind of of preferred embodiment, such as Ju Bu change or modification and come from technological thought of the present utility model and be have the knack of this skill the people was easy to know by inference, all do not take off patent right category of the present utility model.
