[0033] It should be noted that the clamp body 1 is configured as a U-shaped structure to adapt to air ducts of different sizes, thereby improving the applicability of the clamp body 1.

[0034] See also Figure 2In order to quickly and effectively fix the air duct body 2, the positioning mechanism 3 in this embodiment includes a plurality of hinge seats 31, a plurality of hinge rods 32, a plurality of hook claws 33, a plurality of first telescopic rods 34 and a plurality of compression springs 35. The plurality of hinge seats 31 are fixed to the top of the opposite side of the left and right side walls of the inner cavity of the card body 1, the hinge rods 32 are hingedly connected to the hinge seats 31, the hook claws 33 are fixed to the lower surface of the hinge rods 32, and the plurality of first telescopic rods 34 are fixed to the bottom between the card body 1 and the opposite side of the hook claws 33. The compression springs 35 are movably sleeved on the outer surface of the first telescopic rods 34. The air duct body 2 is placed in the inner cavity of the card body 1, so that the hook claws 33 are subjected to pressure and the first telescopic rods 34 and the compression springs 35 are shortened. Then, the left end of the fastening screw 4 is fixed to the top of the left end of the card body 1, so that the top of the card body 1 is fixed to prevent the air duct body 2 from detaching, and then the hook claws 33 can be automatically reset and tightly hook the outer wall of the air duct body 2, thereby enhancing the anti-falling effect.

[0035] In this embodiment, a plurality of hinged seats 31, hinged rods 32, hooks 33, first telescopic rods 34 and compression springs 35 are evenly distributed on the opposite side of the left and right side walls of the inner cavity of the card body 1.

Fixed on the opposite side of the two arc-shaped clamping plates 52, the two pull rods 55 are pulled toward the side away from the mounting block 51, and the movement of the pull rods 55 drives the arc-shaped clamping plates 52 to move, so that the two arc-shaped clamping plates 52 move away from each other, and the protruding rods 56 are fixed in pairs at the left and right ends of the opposite side of the two arc-shaped clamping plates 52. The movement of the two arc-shaped clamping plates 52 drives the protruding rods 56 fixed to the arc-shaped clamping plates 52 to move. At this time, the second telescopic rod 53 and the return spring 54 are squeezed until the left end of the fastening screw 4 can pass through the mounting block 51.

[0038] In this embodiment, limiting grooves are provided on the opposite sides of the front and rear side walls of the inner cavity of the mounting block 51, and limiting blocks are fixed on the front and rear sides of the arc-shaped clamping plate 52.

[0040] It should be noted that after adjusting the fastening screw 4 to an appropriate extension length, the two pull rods 55 can be loosened, the return spring 54 rebounds and drives the second telescopic rod 53 to extend, thereby pushing the two arc-shaped clamping plates 52 to move relative to each other, until the protruding rods 56 at the upper and lower ends enter the grooves 6 on the surface of the fastening screw 4, and the left end of the fastening screw 4 can be fixed. Since the right end of the fastening screw 4 is threadedly connected to the right end of the clamp body 1, the stability of the fixation of the fastening screw 4 is further improved, thereby achieving faster installation and disassembly operations.

[0041] The working principle of the above embodiment is:

[0042] (1) When positioning the air duct body 2, the fastening screw 4 is not fixed to the top of the left end of the clamp body 1. The hook 33 is in an inclined state due to the action of the first telescopic rod 34 and the compression spring 35. The air duct body 2 is placed in the inner cavity of the clamp body 1, so that the hook 33 is subjected to pressure and the first telescopic rod 34 and the compression spring 35 are shortened. Then, the left end of the fastening screw 4 is fixed to the top of the left end of the clamp body 1, so that the top of the clamp body 1 is fixed to prevent the air duct body 2 from detaching. Then, the hook 33 can be automatically reset and tightly hooked to the outer wall of the air duct body 2, thereby enhancing the anti-falling effect.

[0043] (2) When fixing the fastening screw 4, the fastening screw 4 can be rotated to the left so that the left end of the fastening screw 4 enters the through hole opened at the top of the left end of the clamp body 1, and then the two pull rods 55 are pulled to the side away from the mounting block 51. The movement of the pull rod 55 drives the arc-shaped clamping plate 52 to move, so that the two arc-shaped clamping plates 52 move away from each other, and drives the protruding rod 56 fixed to the arc-shaped clamping plate 52 to move. At this time, the second telescopic rod 53 and the return spring 54 are squeezed until the left end of the fastening screw 4 can pass through the mounting block 51. After adjusting the fastening screw 4 to an appropriate extension length, the two pull rods 55 can be loosened, the return spring 54 rebounds and drives the second telescopic rod 53 to extend, thereby pushing the two arc-shaped clamping plates 52 to move relative to each other until the protruding rods 56 at the upper and lower ends enter the grooves 6 on the surface of the fastening screw 4, and the position of the fastening screw 4 can be fixed.
