Technical Field

[0001] The utility model relates to the technical field of tripods, in particular to a tripod which can be adjusted and leveled by a knob. Background Art

[0002] The role of a tripod cannot be ignored for both amateur and professional users. Its main function is to stabilize the camera in order to achieve certain photographic effects. The most common use of a tripod is in long exposure. If the user wants to shoot night scenes or pictures with moving tracks, the exposure time needs to be increased. At this time, the digital camera cannot shake, so a tripod is needed. There are many choices of tripods. In fact, the main purpose of buying a tripod is to provide a stable shooting state for some shooting situations.

[0003] For example, the announcement number is: CN106996771B (named "A tripod device that is easy to level"), which includes a tripod that is in contact with the ground and has an adjustable height, and a support platform arranged at the upper end of the tripod, wherein the tripod includes three evenly distributed support legs, and a support hole that passes through the middle of the support platform is arranged, and further includes: a horizontal adjustment mechanism, a locking mechanism and an instrument installation platform; the horizontal adjustment mechanism is an axially symmetrical body with a plumb line as the symmetry center, including: a cylindrical support rod arranged vertically, a truncated cone-shaped support platform arranged horizontally on the top of the support rod, and a support hole arranged on the upper end of the support platform. A conical weight at the bottom of the support rod, and a spherical rotating shaft body arranged on the support rod near one end of the support platform; a clamping sleeve is arranged outside the rotating shaft body, and a through hole is arranged in the middle of the clamping sleeve which passes through the upper and lower parts, and the through hole has a concave spherical surface matching the rotating shaft body, forming a rotating shaft cavity for accommodating the rotating shaft body, and the horizontal adjustment mechanism is rotatably mounted in the rotating shaft cavity through the rotating shaft body; the clamping sleeve is clamped in the bracket hole to keep the horizontal adjustment mechanism always vertical, and the horizontal adjustment mechanism is locked and fixed by a locking mechanism arranged between the tripod and the horizontal adjustment mechanism.
