The novelty and other features of the present invention will be apparent from the following detailed description of the embodiments of the drawings.

As shown in the first and second embodiments, in the preferred embodiment, the present invention is provided with a rotating shaft 10 including a main shaft of a set size and diameter, and the rotating shaft 10 is provided with a reduced diameter shaft 11 at one end, the reduced diameter The shaft 11 has upper and lower opposite flat faces 12 for forming a shorter lateral width W and a longer longitudinal length L in the shaft, and at the same time, preferably between the end of the reduced diameter shaft 11 and the main shaft of the rotating shaft 10. The utility model is provided with a shoulder 13 for expanding the diameter, and a screw end 14 at the other end; a pair of tabs 15 are arranged on the outer side of the main shaft of the rotating shaft 10 for assembling the electronic device (such as a tablet) Rack (not shown in this figure).

A fixed bracket 20 is assembled to the reduced diameter shaft 11 and abuts one end of the entire fixed bracket 20 to the shoulder 13. The fixed bracket 20 is provided with a through-reduced shaft An elastic shaft tube 21 of the elliptical tube 21, the elastic shaft tube 21 is provided with a set diameter (such as a shorter transverse width W than the reduced diameter shaft 11 and slightly smaller than the longitudinal length L) An elastic notch 23 is provided; the entire fixing bracket 20 is extended and a fixing piece 24 is extended. At the same time, the inner hole 22 is preferably provided with upper and lower opposite inner cutting planes 25, 26 (see FIGS. 5 and 6 for details), so that the opposite ends of the inner cutting planes 25, 26 can be used as a blocking device for the rotation stroke. .

A fixed inclined block 30 is sequentially pressed against the fixed bracket 20 to be assembled to the reduced diameter shaft 11 , and the fixed inclined block 30 is provided with a central hole movable through the reduced diameter shaft 11 31, and a low-step surface 32 is disposed at one end, and the low-order surface 32 is provided with at least one arc-shaped protrusion portion toward the outer side. In this embodiment, the arc-shaped protrusion portion is two oppositely-divided tapered protrusions 33. 34, the conical protrusions 33, 34 are converged from the lower step surface 32 by an obliquely outwardly narrowing width to an end of an arc; The oblique block 30 extends toward one end with an opposite fixing piece 35 of the fixing piece 24 of the fixing bracket 20.

An movable inclined block 40 is sequentially pressed against the fixed inclined block 30 and coupled to the reduced diameter shaft 11 in an interlocking manner. In this embodiment, the movable inclined block 40 includes the reduced diameter rod The inner hole 41 of the same section of the body 11 is inserted and coupled, and the movable inclined block 40 and the opposite end portion of the arcuate protrusion of the fixed oblique block 30 are provided with opposite low-order faces and arc-shaped protrusions. In this embodiment, the opposite arcuate projections are the same two spaced apart opposing conical projections 42 (only one of which is shown in the drawings), and in the normal state, the conical projections 33, 34 and relative The conical projections 42 abut each other near the end of the arc (see Figures 1 and 3 for details).

One end of a compression spring 50 abuts against the other end of the arcuate protrusion of the movable block 40 and is movably assembled to the reduced diameter shaft 11 and then locked to the thread end by a nut 60. 14 Position all components and place the compression spring 50 in a set pressurized state.

As shown in the third and fourth figures, according to the above-described automatic bounce mechanism, when the rotating shaft 10 is rotated by force, the reduced-diameter shaft 11 will synchronously interlock the movable inclined block 40 as shown in FIG. 3, so that The movable slanting block 40 is rotated along the circumferential arrow so that the arcuate projections and the opposite arcuate projections (ie, the conical projections 33, 34 and the opposite conical projections 42) of the fixed slanting block 30 and the movable slanting block 40 are phased. The axial arrow displacement is gradually generated by the inclined surface to further push the compression spring 50 toward the end of the arc. At this time, the compressed compression spring 50 will release the reverse axial tension as indicated by the arrow as shown in FIG. The block 40 is further deflected to produce a reverse axial displacement, thereby interlocking the reduced diameter shaft 11 such that the set tabs 15 provided at one side end interlock the electronic device stand.

As shown in FIGS. 5 and 6, the longer longitudinal length L of the reduced diameter shaft 11 will be rotated by the fifth figure due to the deflection during the normal to automatic bounce of the reduced diameter shaft 11. By the position shown in Fig. 6, it is thus possible to force the elastic shaft tube 21 to form a positioning clamp when the mechanism is actuated. For the force, and through the inner hole 22, it is preferable to provide a cutting plane 12 which is vertically opposed to the end of the reduced-diameter shaft 11 on both sides of the inner-cut planes 25, 26 as a blocking means for the stroke. In this embodiment, the reduced-diameter shaft 11 including the upper and lower opposing cutting planes 12 is inserted into the elastic shaft tube 21 (known as the unit cell structure), which has the advantages of simple structure, easy manufacture, and low cost, but this A structure is only used for convenience of illustration and is not intended to be limiting.

As shown in Figures 7 and 8, the present invention is thus configurable through a predetermined fixing piece 24 and a relative fixing piece 35 to be disposed at opposite positions on the back sides of the electronic device (such as the tablet computer 70). The tablet 70 is preset to be relatively concave. The entry area 71 is provided in a normal state (i.e., the stand 80 is not opened as shown in Fig. 7), and a relative shape of the stand 80 is combined in a flat manner such that the side edges 81, 82 of the stand 80 are close to the upper end position. The set of tabs 15 disposed on one side of the rotating shaft 10 (not shown) are respectively connected; at the same time, in the normal state, the main body of the tripod 80 and the tablet computer 70 are respectively provided with attachment means 90 at opposite positions. The attachment device 90 is a relative magnet element, and can be used to fold the tripod 80 in a normal manner, and when the tripod 80 is disengaged, the rotating shaft 10 is matched with the elastic shaft tube 21 and relatively fixed obliquely. The block 30 and the movable ramp 40 and the compression spring 50 automatically bounce the stand 80 to the set support angle as described above (as shown in Fig. 8), and vice versa, the stand 80 can be pushed back in the opposite direction. Normally flatten the storage position.

The creation thus provides an improved automatic lifting mechanism for the tripod, which is simpler in structure, and is also manufactured and assembled in the factory. At the same time, the opening or closing action of the tripod of such electronic equipment is also faster. And convenient.
