In the multi-legged support implementing the embodiment of the present invention, at least one of the legs 2 is a telescopic leg 2a, and when the multi-legged support is not used, the first supporting member 100 is slidable relative to the second supporting member 200, so that the length of the telescopic leg 2a is shortened, and the occupied volume of the multi-legged support is reduced. And, when using this multi-legged support, the length of flexible stabilizer blade 2a is adjustable for multi-legged support can adapt to the unevenness better, or the holding surface that inclines.

For example, when the multi-legged support is placed on a rugged support surface, if the retractable legs 2a are suspended with respect to the support surface, the retractable legs 2a can be adjusted to contact the support surface by adjusting the retractable legs 2a.

By way of example, the multi-legged stand may be a three-legged stand, a four-legged stand, a five-legged stand, a six-legged stand, i.e. the number of legs 2 of the multi-legged stand may be 3, 4, 5, 6, etc.

Illustratively, the electric main body 3 may be a fan, a lamp, a mobile phone, a panel, etc., for example, the fan, the lamp is fixedly or movably mounted on the support rod 1, for example, the mobile phone and the panel may be clamped by a clamp 4, and the clamp 4 is fixedly or movably mounted on the support rod 1.

Preferably, an embodiment of the present invention further provides a shooting support, which includes a shooting terminal 3 and the multi-pin support, where the support rod 1 of the multi-pin support is used to support the shooting terminal 3, and the shooting terminal 3 may be a mobile phone, a tablet, or the like.

Illustratively, at least one leg 2 is fixedly mounted to the support rod 1, e.g., at least one telescoping leg 2a is fixedly mounted to the support rod 1, e.g., a first support or a second support of the telescoping legs 2a is fixedly mounted to the support rod.

Illustratively, each of the at least three legs 2 is fixedly mounted to the support rod 1, and the at least three legs 2 are radially expandable relative to the support rod 1. For example, all the legs 2 are telescopic legs 2a, at least three telescopic legs 2a are fixedly mounted on the support rod 1, and at least three telescopic legs 2a are radially openable relative to the support rod 1.

Illustratively, the angle of the at least one leg 2 relative to the support bar 1 may vary, in particular, the at least one leg 2 may be rotatable relative to the support bar 1, more particularly, the at least one leg 2 may be directly or indirectly rotatably connected to the support bar 1; for example, the angle between the at least one telescopic leg 2a relative to the support bar 1 may vary, in particular, the at least one telescopic leg 2a may be rotatable relative to the support bar 1, more in particular, the at least one telescopic leg 2a may be directly or indirectly rotatably connected to the support bar 1, e.g., the first support or the second support of the telescopic leg 2a may be directly or indirectly rotatably connected to the support bar.

Illustratively, at least one of the legs 2 is retractable or openable with respect to the support bar 1, e.g., at least one of the telescoping legs 2a is retractable or openable with respect to the support bar 1.

Illustratively, at least three legs 2 are each retractable or openable with respect to the support rod 1, and at least three legs 2 are retractable in the support rod 1 after the first support 100 of the retractable leg 2a is retracted in the second support 200 of the retractable leg 2a, for example, at least three legs 2 are each movably mounted to the support rod 1, and when at least three legs 2 support the support rod 1, at least three legs 2 are radially opened with respect to the support rod 1; when the multi-leg bracket is not used, at least three support legs 2 can be mutually folded, or at least three support legs 2 are contained in the support rod 1. For example, after the at least three legs 2 are received in the supporting rod 1 and the first supporting member 100 is received in the second supporting member 200, the at least three legs 2 may form a first column structure. The first columnar structure can be a cylinder, an elliptic cylinder, a prism and a rounded prism.

For example, the at least three legs 2 are all telescopic legs 2a, and after the at least three legs 2 are received in the supporting rod 1 and the first supporting member 100 is received in the second supporting member 200, the at least three telescopic legs 2a may form a first cylindrical structure. For example, the cross section of the second supporting member 200 is arc-shaped or fan-shaped, when the at least three telescopic legs 2a are folded, the second supporting member 200 of the at least three telescopic legs 2a is folded to form a first cylindrical structure.

Illustratively, at least three legs 2 may exhibit an equal length, or at least two legs 2 of the at least three legs 2 may exhibit an equal length, or at least three legs 2 may exhibit different lengths between two legs.

For example, at least three legs 2 may be opened at equal angles with respect to the support bar 1, or at least two legs 2 may be opened at equal angles with respect to the support bar 1, or any two legs 2 may be opened at different angles with respect to the support bar 1.

Illustratively, the support bar 1 is perpendicular to the support surface or the support bar 1 is inclined with respect to the support surface when the multi-legged stand is in the support state.

This has the advantage that the length of the telescopic legs 2a can be adjusted when using the multi-legged stand, so that the support area of the multi-legged stand can be changed, for example, when the length of the support rod 1 is long or the weight of the power consumption body 3 is heavy, the length of the telescopic legs 2a can be adjusted so that the support area of the multi-legged stand becomes large.

Illustratively, the at least three legs 2 are all telescopic legs 2a, and after the at least three telescopic legs 2a change their lengths, the included angle between the supporting rod 1 and the supporting surface is not changed (for example, the supporting rod 1 is perpendicular to the supporting surface, or inclined).

Illustratively, the at least three legs 2 are all telescopic legs 2a, and the angle between the support rod 1 and the plumb line is unchanged after the at least three legs 2 change the length thereof (for example, the support rod 1 always follows the plumb line, or has an angle with the underline).

For example, the first support 100 is sleeved on the second support 200, and the second support 200 may be completely wrapped around the first support 100, or the second support 200 is partially wrapped around the first support 100.

Illustratively, the first damping protrusion 110 is in damping contact with the second support 200, the first damping protrusion 110 is tightly fitted with the second support 200, and the first damping protrusion 110 and the second support 200 have a friction force, so that the first support 100 can be positioned on the second support 200.

Illustratively, the second supporting member 200 is provided with a first sliding groove 201, the first supporting member 100 is slidably sleeved in the first sliding groove 201, and the first damping protrusion 110 is in damping contact with an inner wall of the first sliding groove 201.

Illustratively, the first support 100 is fully wrapped, half wrapped, or partially wrapped by the second support 200.

In some implementations of the invention, referring to fig. 15 and the like, the first sliding groove 201 is a cylindrical groove, and the first support 100 is circumferentially fixed relative to the first sliding groove 201.

Illustratively, the cross section of the first sliding groove 201 is "c" shaped, the first support 100 has a portion with the cross section of "c", and the portion with the "c" shape of the first support 100 is matched with the first sliding groove 201, for example, the first sliding groove 201 may be a closed "c" shaped groove, or a "c" shaped groove with an opening. This has the advantage that the structural strength of the telescopic leg 2a is increased.

Illustratively, the cross section of the first sliding groove 201 is semicircular, elliptical, polygonal, etc., and accordingly, the first support 100 has a portion (and the portion is engaged with the first sliding groove 201) having a semicircular, elliptical, polygonal cross section.

It is understood that the first supporting member 100 can be positioned on the second supporting member 200 when the telescopic leg 2a is in the supporting state, which means that the first supporting member 100 can be kept on the second supporting member 200 when the telescopic leg 2a is in the supporting state.

It can be understood that when the first support 100 is received in the second support 200, the damping contact between the first support 100 and the second support 200 can position the first support 100 in the second support 200 (i.e. the first support 100 is kept in the received state relative to the second support 200).

In other examples, the first sliding groove 201 is a cylindrical groove with a cross section having any other shape, such as a cylindrical groove, and the first sliding portion 140 is a cylindrical body with a cross section having any other shape, such as a cylindrical body.

In some implementations of the embodiment of the invention, referring to fig. 9, 15, and the like, the first support 100 includes a first support body and a first damping protrusion 110 protruding from the first support body, and the first damping protrusion 110 is in damping contact with the first sliding groove 201, so that the first support 100 is in damping contact with the first sliding groove 201. The first damping protrusion 110 is provided to provide a frictional damping to the first and

second supports

100 and 200 at any position where the first damping protrusion 110 is in a damping contact with the first sliding groove 201.

For other examples, the second sliding groove 203 is a cylindrical groove with a cross section having any other shape, such as a cylindrical groove, and accordingly, the first body 130 is a cylindrical body with a cross section having any other shape, such as a cylindrical body.

In some implementations of the embodiment of the present invention, referring to fig. 11, 18, etc., the first supporting member 100 has a third positioning protrusion 132, the second positioning protrusion 221 can abut against or can slide over the third positioning protrusion 132 during the sliding process of the first supporting member 100 relative to the second supporting member 200, the second supporting member 200 has a second positioning protrusion 221, and when the telescopic leg 2a is in the contracted state, the third positioning protrusion 132 abuts against the second positioning protrusion 221, so that the first supporting member 100 can be prevented from sliding out of the second supporting member 200. The advantage of this arrangement is that when the first support 100 is received in the second support 200, the first support 100 is retained in the second support 200, and the first support 100 is prevented from sliding relative to the second support 200, thereby preventing the telescopic leg 2a from being received.
