In order to improve this deficiency, the present invention provides an adjustable tripod.

[0005] To achieve the above-mentioned purpose, the present invention is realized through the following technical solutions:

[0006] The two lever arrangement comprises a first end mounted on the bottom surface of the second support frame, and a second end mounted on the bottom surface of the second support frame, wherein the first and second side levers are connected along the longitudinal direction of the swing arm to form a loop of motion.

[0007] As a preferred solution, the outer clip includes a first clipping portion clipped onto the vertical rod, the outer end surface of the first clipping portion is integrally provided with a first connection portion connected to the inner clip, the inner clip includes a second clipping portion clipped onto the extension rod, the outer peripheral surface of the second clipping portion is integrally provided with a second connection portion connected to the outer clip, and the brake pad is located between the first connection portion and the second connection portion.

[0008] As a preferred solution, vertical waist-shaped grooves are opened on the side surfaces of the two outer clips, and the pressing part is slidably connected in the waist-shaped grooves.

[0009] As a preferred solution, a protrusion is provided on the inner surface of the outer clamp, the brake pad is sleeved on the protrusion, and the end surface of the brake pad protruding from the protrusion abuts against the outer end surface of the inner clamp.

[0010] As a preferred solution, the base includes a first hinged seat that is detachably connected to the middle part of the vertical rod, each first hinged seat is hinged with an inclined support rod, each support rod is hinged with a connecting rod in the middle, a second hinged seat is sleeved on the bottom of the vertical rod, and the free end of the connecting rod is hinged to the corresponding second hinged seat.

[0011] Compared with the prior art, the present invention has the following beneficial effects: the device can extend the extension rod or adjust it from a vertical position to a horizontal position by adjusting the position of the handle and the positioning pin, so that the angle of the lamp is wider and the distance and intensity of the light are easier to adjust. The horizontally arranged extension rod can suspend the lamp directly above the photographer without hindering the photographer's composition and framing. It is suitable for industrial production and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS
