The further technological scheme of the utility model is: a kind of swivel hinge mechanism, comprise rotary seat, be installed in vertical mandrel and horizontal mandrel on the rotary seat respectively, described vertical mandrel one end pivot sleeve is located in the rotary seat, the other end and a swivel base are fixed, described rotary seat is provided with axially outside retaining angle projection towards an end of swivel base in vertical mandrel outer ring, state swivel base and be provided with the angle corresponding with keeping off the angle projection and collude; Described horizontal mandrel is vertically fixed on the rotary seat with vertical mandrel, be arranged with fixed base on the described horizontal mandrel, described horizontal mandrel is the cydariform cylinder that cylinder is cut into, axis hole on the described fixed base is for having the word hole that projection forms in the circular hole inboard, the plane of described horizontal mandrel contacts with the projection in word hole, and the arc surface of described horizontal mandrel matches with the circular arc portion in word hole.
Described vertical mandrel upper end is provided with the cap portion of external diameter greater than vertical outside diameter of mandrel, vertical axis hole on the described rotary seat has the top that holds cap portion and internal diameter and the vertical bottom of mandrel corresponding matching, described vertical mandrel is arranged with the pipe spring in cap subordinate side, described pipe spring lower end is supported on the step of being located between vertical axis hole top and the bottom, described vertical mandrel is fixed with nut in the swivel base outer end, also is folded with shell fragment between described nut and the swivel base.
The utility model advantage is:
1. the horizontal mandrel of the utility model is that the cross section is the cydariform axle, it matches with 8 font axis holes on the fixed base, make horizontal mandrel to rotate in the several angle scope with respect to fixed base, this angle limit structure does not need extra increase component, and is simple in structure.
2. the vertical mandrel of the utility model can rotate with respect to rotary seat, the swivel base face relative with rotary seat on the vertical mandrel of being fixed on is provided with the angle of the hook retaining that cooperatively interacts and colludes and keep off the angle projection, its limit structure is simple, make that the swivel hinge mechanism volume is littler, meet the demand of user the electronic product portability.

Embodiment
Below in conjunction with drawings and Examples the utility model is further described:
Embodiment: extremely shown in Figure 5 as Fig. 1, a kind of swivel hinge mechanism, comprise rotary seat 1, be installed in vertical mandrel 2 and horizontal mandrel 3 on the rotary seat 1 respectively, described vertical mandrel 2 one end pivot sleeve are located in the rotary seat 1, the other end and a swivel base 4 are fixing, described rotary seat 1 is provided with axially outside retaining angle projection 5 towards an end of swivel base 4 in vertical mandrel 2 outer rings, stating swivel base 4 is provided with the angle corresponding with keeping off angle projection 5 and colludes 6, when swivel base 4 colludes 6 when arriving retaining angle projections 5 along with vertical mandrel 2 turns to angle with respect to rotary seat 1, rotation is limited, and has so just reached the spacing effect of angle.Described vertical mandrel 2 upper ends are provided with the cap portion 9 of external diameter greater than vertical mandrel 2 external diameters, vertical axis hole 10 on the described rotary seat 1 has the top that holds cap portion 9 and internal diameter and the vertical bottom of mandrel 2 corresponding matching, described vertical mandrel 2 is arranged with pipe spring 11 in cap portion 9 belows, described pipe spring 11 lower ends are supported on the step of being located between vertical axis hole 10 tops and the bottom, described vertical mandrel 2 is fixed with nut 12 in swivel base 4 outer ends, also is folded with shell fragment 13 between described nut 12 and the swivel base 4.After 12 lockings of shelves nut, can oppress shell fragment 13 distortion, thereby produce torsion.
