When it is necessary to adjust downward, the arc-shaped tooth block 145 is moved away from the circular tooth block 231 by pulling the handle 2 146, and the support for the circular tooth block 231 is cancelled. The connecting column 21 can fall down, thereby driving the collecting device 241 to fall together, and then the handle 2 146 is loosened, and the arcuate tooth block 145 is rebounded by the resilience of the spring 144, so that the arcuate tooth block 145 returns to its original position and contacts the circular tooth block 231 again to support it, so that the connecting column 21 will not fall down, and the threaded rod 221 is rotated counterclockwise to drive the pressing plate 222 to leave the sliding rod 211 to cancel the fixation of the sliding rod 211, and then the sliding rod 211 can be pulled to adjust the length of the collecting device 241 to control the extended length. When the extended length reaches the user's requirement, , the threaded rod 221 can be rotated clockwise to make the pressing plate 222 press the sliding rod 211 to fix it. The support platform 12 does not require the staff to lift the long rod for a long time to collect sound, so that the collected sound source is more stable. The height and length of the collection device 241 can be adjusted by connecting the column 21. When collecting sound, it can cope with a variety of video shooting scenes, and the effect of use is more comprehensive. By pulling the handle three 43 to move the arc clamping plate 3, the rack 41 will be driven to move together when the handle three 43 is pulled. When the rack 41 moves, the gear 4 will be driven to rotate, so that the right side The racks 41 are moved together so that the two racks 41 are away from each other, so that the two arc-shaped clamping plates 3 are separated from the turntable 13, and the fixation of the turntable 13 is cancelled so that the turntable 13 can be rotated, thereby adjusting the direction of the collection device 241. After the adjustment is completed, the handle three 43 is relaxed and the two arc-shaped clamping plates 3 will be rebounded by the rebound force of the spring two 32 to return to the position to fix the turntable 13. By rotating and adjusting the direction of the collection device 241, there is no need to change the direction of the support platform 12, so that the sound in different directions of the video shooting can be collected, and the operation is easy, thereby reducing the labor intensity of the staff.
