The unlocking body 1251 is movably provided in the quick-release plate 122, and the end of the unlocking body 1251 passes through the quick-release plate 122 to be exposed to the outside. The first protrusion 1252 is fixedly provided on the side of the unlocking body 1251. The first protrusion 1252 is movably provided at the first movable groove 1223, and the end of the first protrusion 1252 passes through the quick-release plate 122 to be exposed to the outside. The adapter 124 is exposed at the third mounting position 1221 through the first movable groove 1223; the adapter 124 is provided with a limiting portion 1241, and the limiting portion 1241 is provided with a positioning groove 1242 and a first guide slope 1243 to guide the first protrusion 1252 to move along the first movable groove 1223, the positioning groove 1242 and the first guide slope 1243 are connected, and the end of the first protrusion 1252 can move into the positioning groove 1242 along the first guide slope 1243 to increase the structural stability.

At this time, the second protrusion 1254 extends out of the second movable groove 1224 under the action of the first elastic member 1256 and abuts against the blocking surface 1262, so that the positioning assembly 125 will not be directly reset, that is, the first protrusion 1252 is in a state of leaving the positioning groove 1242. At this time, the adapter 124 can be slid and taken out. After the adapter 124 is taken out, the positioning assembly 125 is reset under the action of the second elastic member 1253.

The positioning protrusion 1135 is triangular in shape, and the two sides of the positioning protrusion 1135 correspond to the states of the locking member 1132 extending into and out of the locking hole 1281 respectively; specifically, when the toggle member 1131 is toggled, the positioning protrusion 1135 is abutted against to compress the third elastic member 1134, and the toggle member 1131 is toggled from one side of the positioning protrusion 1135 to the other side of the positioning protrusion 1135, and the third elastic member 1134 drives the positioning protrusion 1135 to reset to clamp the toggle member 1131, thereby realizing the state switching of the locking member 1132.

[0069] See also Figure 7-8 In this embodiment, a rotating surface 1271 is provided on the first mounting component 127 , and the second driving component 3 is drivingly connected to the rotating surface 1271 .

[0070] In this embodiment, a second limiting member 1272 is provided on the rotating surface 1271, and a second limiting track 1111 is provided at the first support arm 111 corresponding to the second limiting member 1272, and the second limiting member 1272 is movably provided in the second limiting track 1111. With the provision of the second limiting track 1111, when the second driving assembly 3 drives the first mounting assembly 127 to pitch and rotate, the second limiting member 1272 moves in the second limiting track 1111, and the pitch rotation range of the first mounting assembly 127 is limited by the cooperation of the second limiting member 1272 and the second limiting track 1111.

[0071] In this embodiment, a second sensing member 1273 is provided on the rotating surface 1271, and a second stroke detection member 1112 for detecting the position of the second sensing member 1273 is provided on the first support arm 111, and the second stroke detection member 1112 corresponds to the position of the second sensing member 1273. The second stroke detection member 1112 can detect the stroke of the pitch rotation by detecting the position of the second sensing member 1273. With such a configuration, the rotation stroke can be safely detected, and a software limit is provided; specifically, the mechanical limit angle of the second limit member 1272 and the second limit rail 1111 can be slightly larger than the software limit angle, so that the mechanical limit has a margin, thereby ensuring the safety of the structure during operation. Specifically, the second sensing member 1273 is a magnet, and the second stroke detection member 1112 is a Hall sensor, such as a switch-type Hall sensor. It is worth noting that the pitch stroke limited by the second limit track 1111 is greater than the stroke specified by the software, so as to leave a margin for the rotation of the lamp stand in the process of controlling the rotation of the lamp stand device, so as to ensure the safety of the rotation of the lamp stand device. Furthermore, the extra margin stroke of the second limit track 1111 can be distributed at both ends of the second limit track 1111, so that both the origin and the end point of the pitch rotation of the light 5 have margins.

[0072] In this embodiment, the second drive component 3 includes a second motor 31 and a second harmonic reducer 32. The second motor 31 is fixedly connected to the first support arm 111, and the second motor 31 is connected to the second harmonic reducer 32. The second drive end 321 of the second harmonic reducer 32 is connected to the rotating surface 1271, so that the second motor 31 is driven and connected to the rotating surface 1271 through the second drive end 321 of the second harmonic reducer 32.

[0073] In this embodiment, a hanging ring 6 is provided on both the mounting frame 1 and the control box 2. Herein, the lamp stand device can be installed on a fixed bracket on the ground. In some usage scenarios, the lamp stand device can also be installed by hoisting. In this way, the hanging ring 6 can assist the hoisting installation, for example, by passing some hanging ropes through the hanging ring 6 to help hoist the lamp stand device.

[0074] See also Figure 1 , 10 The control box 2 includes a box body 23, a display screen 24, a shielding member 25 and a third locking assembly 26. The display screen 24 is fixedly arranged on the box body 23, the shielding member 25 is movably arranged on the box body 23, and a convex block 251 is arranged on the shielding member 25. The third locking assembly 26 includes a locking member 262 with a clamping block 261 and a rotating shaft 263. The clamping block 261 can clamp the convex block 251. The locking member 262 is rotatably arranged on the box body 23 through the rotating shaft 263. When the locking member 262 is pressed, the locking member 262 is locked. When the locking block 261 releases the locking protrusion 251, the user can turn over the shielding member 25 to observe the electric control light stand display data on the display screen 24, such as the pitch angle, etc. The user can also reset the shielding member 25 and press the locking member 262 to rotate the locking member 262. When the shielding member 25 is reset, the locking block 261 can be pressed on the protrusion 251 to block the display screen 24 for protecting the display screen 24. It is worth noting that a second spring 264 is also provided between the locking member 262 and the box body 23 to increase the structural stability and provide elastic force to reset the locking member 262. A control button 241 for controlling the information displayed on the display screen 24 is also provided at the display screen 24.
