It can be seen that when the rotational positioning cloud base 1 is rotated, the angle of each rotation is 360 degrees divided by the number of positioning holes 12021 in any positioning hole group 1202.

Referring to fig. 2, in the present embodiment, the number of the positioning holes 12021 in each set of positioning hole group 1202 is two. In order to increase the stability of the rotational positioning cloud base 1, the number of the positioning hole groups 1202 is two, and the total number of the positioning holes 12021 is four. Because the gravity of the screw cap 11 and the first support frame 21 fixedly mounted on the screw cap 11, and the gravity of the mobile phone or the camera clamped on the first support frame 21 are transmitted to the base 12 through the positioning balls 1203, in order to make the base 12 uniformly stressed and not stress concentration, the positioning holes 12021 should be prevented from being concentrated on the base 12, respectively, and the connecting line of the centers of the two positioning holes 12021 in the first positioning hole group 1202 is perpendicular to the connecting line of the centers of the two positioning holes 12021 in the second positioning hole group 1202.

For convenience of rotation, the groove surface of the positioning groove 1111 is a spherical surface adapted to the positioning ball 1203, and the spherical area of the positioning groove 1111 may be smaller than half of the spherical area of the positioning ball 1203, so that the resistance received by the positioning groove 1111 is smaller during rotation.

Referring to fig. 5, in order to reduce the abrasion of the positioning elastic member 1204 on the positioning ball 1203, a bearing member 1205 is further disposed in the positioning hole 12021, and the positioning elastic member 1204 employs a positioning spring 12041. Specifically, the carrier 1205 is a T-shaped structure integrally formed, and includes a carrier plate 12051 and an engaging block 12052.

The gasket 1206 is clamped between the screw cover 11 and the seat body 12, so that when the screw cover 11 is covered on the seat body 12, the screw cover 11 compresses the gasket 1206 due to the gravity of the first support frame 21 and the screw cover 11, so that the screw cover 11, the gasket 1206 and the seat body 12 are tightly pressed; when the positioning ball 1203 is located between the positioning hole 12021 and the positioning slot 1111, the periphery of the positioning ball 1203 is tightly pressed, so that the gap between the inner parts of the seat body 12 is reduced; meanwhile, the arrangement of the gasket 1206 increases the frictional resistance between the screw cover 11 and the base 12, so that when the positioning ball 1203 is positioned between the positioning hole 12021 and the positioning slot 1111, the screw cover 11 and the base 12 are not easy to generate slight dislocation or sliding, the positioning between the screw cover 11 and the base 12 is more stable, and the shooting effect of a camera or a mobile phone is facilitated;

in order to prevent the gasket 1206 from rotating along with the rotation of the cap 11, a protrusion 1207 is disposed at the center of one end of the seat 12 close to the cap 11, and a positioning through hole 12061 is disposed at the center of the gasket 1206, the positioning through hole 12061 is matched with the protrusion 1207, so that the gasket 1206 can be sleeved on the protrusion 1207, and the gasket 1206 is positioned on the seat 12. In order to prevent the spacer 1206 and the positioning balls 1203 from interfering with each other, the spacer 1206 is further provided with ball holes 12062 matching with the positioning holes 12021 in position and size, and in this embodiment, the number of the wall holes is four. Therefore, the spiral cover 11 compresses the gasket 1206, so that the gap between the spiral cover 11 and the base 12 is reduced, the spiral cover 11 and the base 12 are not easy to generate light dislocation or sliding, the positioning between the spiral cover 11 and the base 12 is more stable, and the shooting effect of a camera or a mobile phone is facilitated. The gasket 1206 is made of soft rubber, which is equivalent to a protective layer added between the screw cap 11 and the seat body 12, thereby greatly reducing the abrasion between the seat body 12 and the screw cap 11.

Referring to fig. 9, in order to reduce the gap between the screw cap 11 and the housing 12 when the screw cap 11 rotates on the housing 12 and reduce the deviation of the rotation center when the screw cap 11 rotates, a limit component 13 is disposed at one end of the housing 12 close to the screw cap 11.

In order to rotate the screw cap 11 around the central axis 1201, the limiting space 133 is circular in a direction perpendicular to the central axis 1201. Accordingly, the cap 11 is restricted in the stopper space 133, and the cap 11 can rotate about the center axis 1201.

Referring to fig. 10, for convenience of production, the first stopper 131 and the base body 12 are integrally formed, the second stopper 132 and the base body 12 are also integrally formed, and meanwhile, for convenience of the cap 11 being embedded between the first stopper 131 and the second stopper 132, the first stopper 131 and the second stopper 132 should be able to move away from each other, so the base body 12 includes a first pulling-closing member, a second pulling-closing member and a threaded fastener 1210; in this embodiment, the threaded fastener 1210 employs a fastening bolt 12101.

Thus, the fastening bolt 12101 is coupled between the first drawer member and the second drawer member so that the first drawer member and the second drawer member can be coupled to or separated from each other; and since the first stopper 131 and the first drawing member are integrally formed, the second stopper 132 and the second drawing member are integrally formed. When the first drawing and combining piece and the second drawing and combining piece are connected with each other, the first limiting block 131 and the second limiting block 132 are close to each other; when the first drawing and closing member and the second drawing and closing member are separated from each other, the first stopper 131 and the second stopper 132 are separated from each other. Therefore, the screw cap 11 can be taken away from the first stopper 131 and the second stopper 132, and can also be placed between the first stopper 131 and the second stopper 132 and be limited.

Referring to fig. 11 and 12, in order to stabilize the position between the first stopper 131 and the second stopper 132, an abutting elastic member 1211 is additionally provided.
