[0002] In scenes such as photography and stage, it is often necessary to set up lights to supplement the lighting of different areas. A considerable portion of the lamps used in these scenes are required to be able to change the pitch angle and illumination direction according to the situation. It is also often necessary to replace lamps with matching parameters according to the on-site conditions. Therefore, a lamp stand with two supporting structures is often used as a fixing mechanism for the light source. The light source is fixed between the two supporting members, and the light source is adjusted through the lamp stand to adjust the illumination angle of the light source. Currently, a hard connection is often used between the light source and the lamp stand. In some lamp stands with a driver, since there is a certain locking force between the driver and the light source, the motor and transmission components will be dragged to generate a relatively large reverse force in the process of adjusting the illumination angle of the light source, so that the motor and transmission components in the driver are in a state of unbalanced force, which will significantly affect the service life of the driver.

Common support members on a lamp stand include but are not limited to Figure 1 In the first support member 100 and the second support member 200 shown in the figure, the driving member 102 for driving the light source to rotate is arranged at one end of the first support member 100. Of course, it can be understood that in some other embodiments, the driving member 102 can also be arranged at one end of the second support member 200. In some other embodiments, the driving member 102 can also be arranged at one end of the first support member 100 and one end of the second support member 200 at the same time.

[0040] See also Figure 2 The output end 101 of the driving member 102 is inserted into the first rotating base 301 through the opening on the first rotating base 301, and a first adjusting member 103 is provided at the end of the output end. The first rotating base 301 is movably connected with the first supporting member 100 in the supporting member, that is, the first rotating base 301 can rotate relative to the first supporting member 100 with the output end 101 of the driving member 102 as the axis, and the first rotating base 301 also has an opening, which is used for the output end 101 of the driving member 102 to pass through so that the output end 101 of the driving member 102 is connected to the first supporting member 100. See Figure 2 A first locking assembly 302 is also provided on the first rotating base 301 . The first locking assembly 302 is movably connected to the first rotating base 301 .

[0042] See also Figure 2 and Figure 3 , Figure 3 A schematic diagram of the cross-sectional structure of a lamp stand provided in the present embodiment at the first locking component 302. The first toothed disc 303 is fixed to the end of the output end 101 of the driving member 102 by screws. The first toothed disc 303 plays the role of fixing the first rotating base 301 to prevent the first rotating base 301 from falling off the first supporting member 100, and can also play the role of increasing the contact area and dispersing the force. The first toothed disc 303 is provided with teeth on the side away from the first rotating base 301, and the teeth cooperate with the teeth of the second toothed disc 304 to improve the stability during locking and avoid slipping. It can be understood that the second toothed disc 304 can be a complete toothed disc or only a part of the toothed disc, that is, Figure 2 and 3 shown.

The first locking column 305 also cooperates with the first rotating base 301 through a threaded opening so that the first locking column 305 can change the screwing in and out of the first locking column 305 by changing the rotation direction, thereby realizing the mutual locking or release of the second toothed disc 304 and the first toothed disc 303.

[0043] In some other embodiments, the first locking assembly 302 also includes a first wrench portion 306, one end of the first locking column 305 is connected to the first wrench portion 306, and the other end is connected to the first rotating base 301, and the first wrench portion 306 can drive the second chainring 304 to move closer to or away from the first chainring 303 through the first locking column 305.

One end of the first wrench part 306 is connected to the first locking column 305. The other end of the first locking column 305 passes through the second toothed disc 304 and is then movably fixed on the first rotating base 301. Common connection methods between the first locking column 305 and the first rotating base 301 include but are not limited to threaded connection. The threaded connection can control the screwing in and screwing out of the first locking column 305 by changing the rotation direction of the first locking column 305, thereby driving the second toothed disc 304 to approach or move away from the first toothed disc 303. In this embodiment, the first locking column 305 can be moved by bending the first wrench part 306, and the rotation direction of the first locking column 305 can be adjusted by changing the bending direction. When the first wrench part 306 is bent in the tightening direction, the screw rod of the first locking column 305 is screwed inward, pressing down the second tooth plate 304 until the second tooth plate 304 and the first tooth plate 303 are locked, completing the locking. It can be understood that Figure 2 and Figure 3 The threaded base connecting the first locking column 305 and the first rotating base 301 is an independent component on the first rotating base 301, but in some other embodiments, the threaded base connecting the first locking column 305 and the first rotating base 301 can also be made integrally with the first rotating base 301.
