[0029] Optionally, two lifting mechanisms 3 are arranged at intervals on the frame 1. The ends of the lifting mechanisms 3 are provided with control components 4. The control components 4 include a rotating rod 41, a worm gear 42 and a worm 43. The rotating rod 41 is arranged at one end of the support rod 11 along the second direction. The worm 43 is arranged at both ends of the rotating rod 41. The worm gear 42 is arranged at the end of the double-ended screw 31 with positive and negative threads. The worm gear 42 and the worm 43 mesh.

[0030] Exemplary, in embodiments of this utility model, such as Figure 4 As shown, by setting two lifting mechanisms 3, the stability of the lifting movement of the frame 1 can be improved. A first motor 44 is also set at one end of the rotating rod 41. The first motor 44 drives the rotating rod 41 to rotate. The rotation of the rotating rod 41 drives the worm gear 43 on it to rotate. The worm gear 43 meshes with the worm wheel 42, thereby driving the double-ended screw 31 with positive and negative threads to rotate. By setting the control component 4, the two lifting mechanisms 3 can be linked together, and the slider 32 on them can be driven to slide on the double-ended screw 31 with positive and negative threads, which improves the synchronization of the two lifting mechanisms 3, thereby further improving the structural stability of this live broadcast frame.

[0031] Optionally, a movable seat 5 is slidably provided at the bottom of the support rod 11, and a mounting seat 7 is rotatably provided at the bottom of the movable seat 5.

[0032] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, the movable base 5 is slidably mounted on the support rod 11, allowing the live streaming equipment to be adjusted in position along the support rod 11. The mounting base 7 is rotatably mounted at the bottom of the movable base 5, allowing the orientation of the live streaming equipment to be adjusted. This enables the live streaming equipment mounted on this live streaming rack to adapt to different live streaming needs, thereby improving the applicability of this live streaming rack.

[0033] Optionally, multiple movable seats 5 are provided, and the multiple movable seats 5 are arranged at intervals along the support rod 11.

[0034] For example, in this embodiment of the present invention, by setting multiple movable seats 5, and each movable seat 5 having a mounting base 7 at its bottom, multiple live streaming devices can be set on a support rod 11, thereby increasing the number of live streaming devices that can be installed on the live streaming rack and improving the live streaming effect.

[0035] Optionally, a guide rod 61 arranged along a first direction is provided inside the support rod 11. The guide rod 61 is rotatably disposed inside the support rod 11. A first bevel gear 62 is sleeved on the guide rod 61. A rotating column 63 is provided on the top of the mounting base 7. A second bevel gear 64 is provided on the top of the rotating column 63. The first bevel gear 62 meshes with the second bevel gear 64.

[0036] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, the rotating column 63 is fixed to the top of the mounting base 7 and passes through the bottom of the movable base 5. A second bevel gear 64 is mounted on the top of the rotating column 63, thus the second bevel gear 64 is also located within the movable base 5. A first bevel gear 62 can be fixed to the guide rod 61. When the guide rod 61 rotates, the first bevel gear 62 also rotates simultaneously, thereby driving the second bevel gear 64 to rotate, causing the mounting base 7 to rotate and adjusting the orientation of the live streaming equipment mounted on the mounting base 7. Multiple first bevel gears 62 can be spaced apart on the guide rod 61, each connected to a different second bevel gear 64 on one of the mounting bases 7. This allows multiple live streaming devices to be turned simultaneously when the guide rod 61 is rotated, enabling batch control of multiple live streaming devices. This structure is simple and easy to operate; by controlling the rotation of the guide rod 61, multiple live streaming devices can be turned simultaneously, further improving the ease of operation of this live streaming stand.

[0037] Optionally, the guide rod 61 is a spline shaft, the first bevel gear 62 has a shaft hole at its center that matches the spline shaft, and a fixing block 51 is fixedly installed inside the movable seat 5. The fixing block 51 is located on the side of the first bevel gear 62 away from the second bevel gear 64 and is in contact with the first bevel gear 62.

[0038] Exemplary, in embodiments of this utility model, such as Figure 5 As shown, the guide rod 61 is configured as a spline shaft, so that the guide rod 61 will not slip with the first bevel gear 62 when it rotates, thus ensuring the power transmission between the guide rod 61 and the first bevel gear 62. Furthermore, a fixing block 51 is set in the movable seat 5, and the first bevel gear 62 is clamped between the fixing block 51 and the second bevel gear 64. When the movable seat 5 slides along the support rod 11, the first bevel gear 62 and the second bevel gear 64 can also move with the movement of the movable seat 5. This allows the live broadcasting equipment to simultaneously slide along the support rod 11 and change its orientation, thereby further improving the ease of operation of this live broadcasting stand.

[0039] Optionally, each of the multiple support rods 11 is provided with a guide rod 61, and each of the multiple guide rods 61 is provided with a third bevel gear 65. The end of the support rod 11 is provided with a transmission rod 66 arranged along the second direction, and multiple fourth bevel gears 67 are provided at intervals on the transmission rod 66. The fourth bevel gears 67 mesh with the third bevel gears 65.

[0040] Exemplary, in embodiments of this utility model, such as Figure 6 As shown, a second motor 68 is also provided at one end of the transmission rod 66. When the second motor 68 drives the transmission rod 66 to rotate, it drives the fourth bevel gear 67 to rotate, thereby driving multiple third bevel gears 65 to rotate, which in turn drives multiple guide rods 61 to rotate. This allows the orientation of multiple live streaming devices on multiple guide rods 61 to be adjusted simultaneously. When batch adjustments of live streaming devices are required, the adjustment time can be greatly shortened, thereby further improving the ease of operation of this live streaming stand.
