The abutting surface comprises at least two abutting planes, so that any abutting plane can abut against the outer wall of the telescopic rod 20.

Specifically, referring to fig. 9 to 12, fig. 11 is a schematic diagram of a partial enlarged structure in fig. 9, and fig. 12 is a schematic diagram of a partial enlarged structure in fig. 10. In the present embodiment, the abutment surface comprises two abutment planes, i.e. the abutment surface comprises a first plane 155 and a second plane 156. When the first flat surface 155 abuts against the outer wall of the telescopic rod 20, the leg 14 is folded relative to the telescopic rod 20, and when the second flat surface 156 abuts against the outer wall of the telescopic rod 20, the leg 14 is unfolded relative to the telescopic rod 20.

In particular, when the first plane 155 abuts against the outer wall of the telescopic rod 20, the supporting foot 14 is stressed in a balanced manner, so that the supporting foot 14 can be held on the telescopic rod 20 in a relatively stable manner. When the supporting legs 14 are rotated and opened along the arrow direction shown in fig. 9, the included angle between the first plane 155 and the telescopic rod 20 is gradually increased, the surface-to-surface contact between the first plane 155 and the telescopic rod 20 is gradually changed into the surface-to-surface contact between the boundary line of the first plane 155 and the second plane 156 and the outer wall of the telescopic rod 20, if the acting force acting on the supporting legs 14 is removed at this time, the supporting legs 14 are reset under the action of the tangential force of the telescopic rod 20 to the abutting point of the supporting legs 14 due to unstable surface-to-surface contact, and the first plane 155 continues to abut against the outer wall of the telescopic rod 20, so that the supporting legs 14 are kept in the folded state.

It will be appreciated that in one embodiment, the connection surface is planar. That is, the abutment surface includes three abutment planes connected in sequence. When the first plane 155 of the leg 14 abuts against the outer wall of the telescopic rod 20, the leg 14 is stably kept in the folded state relative to the telescopic rod 20. When the connection surface of the leg 14 abuts against the outer wall of the telescopic rod 20, the leg 14 is stably kept in a small-angle opening state with respect to the telescopic rod 20. When the second plane 156 of the supporting leg 14 abuts against the outer wall of the telescopic rod 20, the supporting leg 14 is stably kept in a wide-angle opening state relative to the telescopic rod 20, so as to realize the variable-angle support of the supporting leg 14, which is convenient for adapting to the external supporting planes a with different sizes, and further improve the compatibility of the support.

In another embodiment, the connecting surface is a circular arc surface. That is, the contact surface includes a first plane 155, an arc surface, and a second plane 156 connected in this order. When the first plane 155 of the leg 14 abuts against the outer wall of the telescopic rod 20, the leg 14 is stably kept in the folded state relative to the telescopic rod 20. When the connection surface of the leg 14 abuts against the outer wall of the telescopic rod 20, the leg 14 can be kept in an open state at any angle relative to the telescopic rod 20. When the second plane 156 of the leg 14 abuts against the outer wall of the telescopic rod 20, the leg 14 is stably maintained in a wide-angle open state with respect to the telescopic rod 20. By providing an arcuate connecting surface connected between the first and second planes 155, 156, the foot 14 can be infinitely adjusted relative to the telescoping rod 20 at a location corresponding to the connecting surface.

As shown in fig. 3 and 13, fig. 13 is a schematic perspective view of the leg of fig. 10 when the leg is opened relative to the telescopic rod. The inner wall of the connecting seat 12 is provided with a hinge groove 121, each of the legs 14 includes a leg 141 and a hinge shaft 140 connected to the leg 141, and the hinge shaft 140 is clamped in the hinge groove 121 and can rotate relative to the hinge groove 121. By clamping the hinge shaft 140 in the hinge groove 121, the mounting and dismounting of the leg 14 can be facilitated, and the number of fixing elements can be reduced, thereby simplifying the structure of the connecting socket 12 and the leg 14 and improving the production and assembly efficiency.

The embodiment of the present invention does not specifically limit the connection mode of the hinge shaft 140 and the leg 141.

In the embodiment, the two opposite ends of the hinge shaft 140 are rotatably connected to the connecting base 12, and a part of the outer side wall of the middle portion of the hinge shaft 140 abuts against the outer wall of the telescopic rod 20 to form an abutting surface in the process that the leg 14 rotates relative to the telescopic rod 20.

Specifically, as shown in fig. 3 and 13, opposite ends of the hinge shaft 140 are respectively inserted into the hinge grooves 121 on the connecting holder 12 and are rotatable with respect to the hinge grooves 121. The middle portion of the hinge shaft 140 abuts against the outer wall of the telescopic rod 20, and the abutment force of the telescopic rod 20 against the leg 14 enables the leg 14 to be relatively held at a predetermined angular position.

Further, as shown in fig. 9 and 13, the legs 141 have an arc-shaped cross section, and the legs 141 are folded to form a hollow cylinder. Specifically, the legs 141 are arc-shaped plates, and when the legs 141 are folded, they can form a hollow cylinder with an open end.

The telescopic rod 20 is slidably inserted through the connecting seat 12 and is accommodated in the hollow cylinder. As shown in fig. 7, when the telescopic rod 20 is in a contracted state, it can be accommodated in the hollow cylinder to reduce the volume of the bracket for easy accommodation. As shown in fig. 8, when the telescopic rod 20 is in the extended state, the telescopic rod 20 extends out from the inside of the hollow cylinder for supporting the photographing apparatus. Moreover, by slidably connecting the connecting seat 12 and the telescopic rod 20, on one hand, when the plurality of support legs 14 are relatively opened and supported on the external support plane a, the telescopic rod 20 can be slid in a direction away from the external support plane a, so as to avoid interference between the telescopic rod 20 and the external support plane a; on the other hand, when the telescopic rod 20 is in the retracted state, the telescopic rod 20 can be slid towards the direction close to the supporting leg 14, so that the size of the support along the axial direction of the telescopic rod 20 is reduced, the size of the support is further reduced, and the support is convenient to store.

Further, as shown in fig. 13, the end of the extendable rod 20 is formed with a retaining portion 21, and when the connecting holder 12 slides to the end of the extendable rod 20, the retaining portion 21 abuts against the end surface of the connecting holder 12. Through set up anticreep portion 21 at the end of telescopic link 20, can be so that the terminal cross sectional dimension of telescopic link 20 is greater than the fenestrate size on connecting seat 12 to avoid telescopic link 20 to deviate from on connecting seat 12.

As shown in fig. 1 and 13, each of the legs 14 further includes a supporting latch plate 143, the supporting latch plate 143 is disposed at the supporting end 142 of the leg 141, and the supporting latch plate 143 is provided with a snap structure for engaging with each other when the plurality of legs 14 are folded.
