Illustratively, at least three of the legs 2 are telescoping legs 2a. The advantage of this is that the length of the telescopic leg 2a is adjustable when the multi-legged support is in use, so that the support area of the multi-legged support is changed, for example when the length of the support bar 1 is long or the weight of the power consuming body 3 is heavy, the length of the telescopic leg 2a can be adjusted, so that the support area of the multi-legged support is enlarged.

Illustratively, at least three of the legs 2 are telescoping legs 2a, and after the length of each of the at least three telescoping legs 2a is changed, the angle between the support bar 1 and the support surface is unchanged (e.g., the support bar 1 is maintained perpendicular to the support surface, or is maintained inclined).

Illustratively, at least three legs 2 are telescoping legs 2a, and after the length of each of the at least three legs 2 is changed, the angle of the support bar 1 to the plumb line is constant (e.g., the support bar 1 is always along the plumb line, or has an angle with the undershot line).

For example, the first supporting member 100 is sleeved on the second supporting member 200, and the second supporting member 200 may be fully wrapped around the first supporting member 100, or the second supporting member 200 may be partially wrapped around the first supporting member 100.

The advantage of this arrangement is that the structural strength of the telescopic foot 2a is improved.

Illustratively, the first sliding groove 201 has a cross-section of a semicircle, an ellipse, a polygon, etc., and accordingly, the first support 100 has a portion having a cross-section of a semicircle, an ellipse, a polygon (and the portion is engaged with the first sliding groove 201).

For example, for a cylindrical geometry, the line along the geometric center of its cross-section is its axis, the direction along the axis is the axial direction of the cylindrical geometry, the direction along the geometric center of the cross-section and perpendicular to the axis is the radial direction of the cylindrical geometry, and the direction about its axis is the circumferential direction of the cylindrical geometry.

It will be appreciated that the first support 100 may be positioned at the second support 200 when the telescopic foot 2a is in the supported state, meaning that the first support 100 may be held at the second support 200 when the telescopic foot 2a is in the supported state.

It will be appreciated that when the first support 100 is received in the second support 200, the damping contact of the first support 100 with the second support 200 may cause the first support 100 to be positioned in the second support 200 (i.e., the first support 100 remains in a received state relative to the second support 200).

For example, the first damping protrusion 110 is protruding on the first support body, the first support body is sleeved on the first sliding groove 201, and in one implementation manner of damping contact between the first support member 100 and the second support member 200, only the first damping protrusion 110 is in damping contact with the first sliding groove 201, and the first support body is not in contact with the first sliding groove 201 (the first support body has a gap with the first sliding groove 201), for example, the first damping protrusion 110 is in a strip shape, the first damping protrusion 110 is looped on the first support body, the first damping protrusion 110 is a plurality of protrusions arranged at intervals, and the plurality of protrusions are arranged at intervals.

On the one hand, when the first damping contact protrusion is in damping contact with the first sliding groove 201, the first deformation opening 101 serves as a deformation space of the first cantilever 120, avoiding an excessive damping force between the first support 100 and the second support 200, and on the other hand, when the first support 100 is fitted into the first sliding groove 201, the first deformation opening 101 serves as a deformation space of the first cantilever 120, so that the first support 100 is easily installed into the second support 200.

For example, the third positioning protrusion 132 sliding over the second positioning protrusion 221 may mean that the telescopic leg 2a is in the storage state, and when the third positioning protrusion 132 is in a state of being abutted against the second positioning protrusion 221 and the tensile force applied to the telescopic leg 2a is sufficiently large, the third positioning protrusion 132 slides over the second positioning protrusion 221, so that the first supporter 100 may be protruded from the second supporter 200.
