Main shaft 10 is provided with boss 102, bayonet lock 103, groove 104 and scotch 105.Boss 102 is ends that are arranged at main shaft 10.Bayonet lock 103 stretches out on the end face of boss 102, and it is a non-axial symmetry cylinder, promptly can be the polygon cylinder, is used for main shaft 10 is fixedly installed in the body of portable electronic equipment, and stops main shaft 10 to rotate relative to the portable electronic equipment body.The other end of main shaft 10, and be provided with groove 104 near the position of this end face, main shaft 10 these ends (figure does not show) have chamfering and install with convenient.Scotch 105 is cylinders, and it is symmetricly set on the main shaft 10, and near boss 102 and bayonet lock 103, this scotch 105 can be one-body molded with main shaft 10, also can offer a hole on main shaft 10, inserts in this hole by a pin to form again.

The hollow circular cylinder of driven member 20 for having cylindrical bore 204, it comprises end face 201 and rotation prevention portion 202.The slightly larger in diameter of its endoporus 204 is in the diameter of main shaft 10.The end face 201 of driven member 20 is provided with V-shaped groove 203, and the open end width of V-shaped groove 203 is less than the diameter of scotch 105, and the junction of itself and end face 201 is that cambered surface is to seamlessly transit; Rotation prevention portion 202 is convexly set on the sidewall of driven member 20, is used for being connected with the lid of folding mobile electronic installation, rotates relative to the portable electronic equipment lid to stop this driven member 20.

Spring 30 is a cylindrical compression spring, and its internal diameter is slightly larger than the diameter of main shaft 10, and its external diameter is not more than the external diameter of driven member 20.

Snap ring 40 which is provided with an endoporus 401 and an opening 402 for having certain thickness C shape ring.The diameter of the external diameter of snap ring 40 and spring 30 is suitable, and the width of its thickness and groove 104 is suitable.Endoporus 401 is located at the middle part of snap ring 40, and the diameter at groove 104 places of its diameter and main shaft 10 is suitable.Opening 402 is located on one side of snap ring 40 and in endoporus 401 and is connected, and its width is less than the diameter of groove 104, and snap ring 40 has certain elasticity, the groove 104 that can opening 402 be opened snap in main shaft 10 by external force.

See also shown in Figure 2, during assembling, the end that main shaft 10 is provided with chamfering passes endoporus 204, the spring 30 of driven member 20 successively, the opening 402 of opening snap ring 40 at last is arranged in it in groove 104, wherein, an end end face 201 of driven member 20 is near boss 102, and scotch 105 somes are arranged in the V-shaped groove 203 of end face 201 recesses, spring 30 is sheathed on the main shaft 10 and between driven member 20 and snap ring 40, and driven member 20 can rotate and can endwisely slip along main shaft 10 relative to main shaft 10.

The portable electronic equipment (figure does not show) that is applicable to the utility model linkage comprises lid and body.Lid (figure does not show) cooperates with the rotation prevention portion 202 of the driven member 20 of linkage, and body (figure does not show) cooperates with the bayonet lock 103 of main shaft 10.When lid is closed with respect to body, the scotch 105 of main shaft 10 fastens with the V-shaped groove 203 of driven member 20, linkage of the present utility model is in metastable state, and because scotch 105 and V-shaped groove 203 snap fit, need to use scotch 105 is skidded off in V-shaped groove 203, phenomenon can not shake and make the relative body of its lid (figure does not show) (figure does not show).

With the lid of portable electronic equipment with respect to the body opening procedure in, main shaft 10 is fixed with respect to body, lid drives driven member 20 and rotates relative to body, the releasing that engages of the V-shaped groove 203 of driven member 20 and scotch 105, scotch 105 is held the last slide relative of smooth end face 201 level with both hands in driven member 20 1, at this moment, driven member 20 endwisely slips along the end of main shaft 10 to tool groove 104, spring 30 is compressed and gathers an elastic force, driven member 20 is under the elastic restoring force effect of spring 30, be resisted against scotch 105, make between end face 201 and the scotch 105 to produce frictional force and keep the optional position to stop.When lid (figure do not show) is subjected to the external force effect, body (figure does not show) when being deployed into maximum angle relatively, the feature of its external structure, scotch 105 keeps stop on the end face 201 of driven member 20, reach stable state.

With lid (figure do not show) with respect to body (figure does not show) by open mode when closed, to lid (figure does not show) body (figure does not show) application of force relatively.Under external force, lid (figure does not show) drives driven member 20 reverse rotations, the scotch 105 of the end face 201 relative main shafts 10 of driven member 20 slides, when lid (figure do not show) body (figure does not show) when forwarding closed relatively position to relatively, V-shaped groove 203 fastens with scotch 105, driven member 20 endwisely slips to tool boss 102 1 ends of main shaft 10, promptly reaches stable state, lid (figure does not show) body (figure does not show) engaging relatively.

Be appreciated that in order to increase the frictional force between its end face 201 and the scotch 105 can be provided with microgroove on this end face 201, this scotch 105 is arranged to a long column body, a plane (figure does not show) is cut at its position that contacts with end face 201.
