[0028] In this embodiment, when the user needs to clamp and fix the whole device, the clamping plate 8 is pulled to drive the sliding blocks 14 to slide horizontally on the fixed rods 15, and the first springs 18 are compressed at the same time. Then, the whole device is placed at the desired fixed position, and the clamping plate 8 is released to reset the first springs 18, the sliding blocks 14 and the clamping plate 8, so that the whole device is fixed at the desired position. The limiting block 17 limits the position of the fixed rod 15 to ensure that the sliding track of the sliding block 14 on the fixed rod 15 is stable and controllable. The fixed rod 15 provides stable guidance for the sliding block 14, so that the sliding block 14 moves linearly along the axial direction of the fixed rod 15, thereby ensuring the smooth opening and closing action of the clamping plate 8.
