[0030] Two primary screws 2 are arranged inside the top plate 1, and the surfaces of the two primary screws 2 are threadedly connected with moving blocks 7, one end of the moving block 7 is fixedly connected with a push tube 8, and the push tube 8 penetrates and extends to the end outside the top plate 1 and is hinged with a rotating plate 9, and the surface of the rotating plate 9 is hinged with an L-shaped fixing member 10 and a push rod 11, and the other end of the L-shaped fixing member 10 is fixedly connected to the top plate 1, and the other end of the push rod 11 is hinged with a clamping assembly 13 arranged inside the vertical plate 12, and two hinged rods 19 are arranged on the other side of the clamping assembly 13, and the other ends of the two hinged rods 19 are hinged with a support plate 20 that is movably against the ventilation duct 26;

[0031] Further explanation: The adjacent end of the primary screw 2 is fixedly connected with a primary bevel gear set 3, the primary bevel gear set 3 includes three meshing bevel gears, one end of the primary bevel gear set 3 is fixedly connected with a rotating shaft 4, one end of the rotating shaft 4 passes through the top plate 1 and is fixedly connected with a rotating disk 5, the surface of the rotating disk 5 is threadedly connected with abutment bolts 6, and the bottom end of the abutment bolts 6 is inserted into the top plate 1;

[0032] The rotating turntable 5 drives the rotating shaft 4 to rotate, and the meshing transmission of the primary bevel gear set 3 further drives the primary screw 2 to rotate, so as to adjust the position of the support plate 20 in all directions. After the support plate 20 clamps the ventilation duct 26, the abutment bolt 6 can be rotated to insert the other end of the abutment bolt 6 into the top plate 1 to fix the primary screw 2, and the device is kept clamped on the ventilation duct 26;

[0033] The surface of the primary screw 2 is fixedly connected with a secondary bevel gear set 24, which includes two mutually meshing bevel gears. The bottom end of the secondary bevel gear set 24 is fixedly connected to the secondary screw 23. The surfaces of the two secondary screws 23 are threadedly connected with a pressing plate 21. One side of the pressing plate 21 and the bottom plate 25 are fixedly connected to the support plate 20.

[0034] The primary screw 2 drives the secondary screw 23 to rotate under the meshing transmission of the secondary bevel gear set 24, so that the pressing plate 21 can move in the vertical direction, so that the upper and lower sides of the ventilation duct 26 are fixed by the support plate 20;

[0035] A plurality of rubber strips 22 are provided on the inner side of the support plate 20; a raised rubber strip 22 is provided on the inner side of the support plate 20, and the support plate 20 clamps the ventilation ducts 26 of different sizes through the deformation of the rubber strip 22, thereby improving the clamping stability;

[0036] After one end of the hinged rod 19 passes through the clamping device 13, it is hinged to the connecting plate 18. The two sides of the connecting plate 18 are fixedly connected with springs 17. The other end of the spring 17 is fixedly connected to another connecting plate 18 or the clamping device 13. When the support plates 20 on both sides abut against the ventilation duct 26, the support plate 20 at the bottom of the pressure plate 21 has not yet abutted against the ventilation duct 26. As the primary screw 2 rotates, the clamping device 13 is driven to move further toward the ventilation duct 26. The angle between the two hinged rods 19 increases, and the hinged rod 19 drives the other end connecting plate 18 to move, so that the spring 17 undergoes different deformations. Under the reaction of the spring 17, the support plates 20 on both sides can clamp the ventilation duct 26;

[0037] L-shaped guide plates 16 are fixedly connected to both sides of the vertical plate 12, and a guide rod 15 is fixedly connected between the two guide plates 16. A guide block 14 is arranged on the surface of the guide rod 15, and a clamping device 13 is fixedly connected to the guide block 14. When the clamping device 13 is pushed by the rotating plate 9 through the push rod 11, the clamping device 13 can move along the guide rod 15 under the action of the guide block 14, and the moving distance of the clamping devices 13 on both sides can be increased, so that ventilation ducts 26 of different sizes can be fixed;

[0038] A sliding groove 27 is provided in the bottom plate 25, a sliding block 28 is slidably mounted in the sliding groove 27, a return spring 29 is welded between the sliding block 28 and the sliding groove 27, and a mounting plate 30 is provided below the bottom plate 25. It should be noted that the mounting plate 30 is provided at the wall position;

[0039] The mounting plate 30 is provided with a receiving groove 31, in which a fixing plate 32 is fixedly arranged, a limiting plate 33 is fixedly connected to the sliding block 28, and a limiting hole 34 corresponding to the limiting plate 33 is provided on the fixing plate 32, and the bottom plate 25 can be connected to the mounting plate 30 through the sliding connection between the limiting plate 33 and the limiting hole 34;

[0040] A driving shaft 35 extending into the sliding groove 27 is rotatably mounted on the base plate 25 via a damping bearing. The damping bearing can ensure the stability of the driving shaft 35 after rotation. A driving disk 36 is fixedly mounted on one end of the driving shaft 35 located in the sliding groove 27. A traction rod 37 is connected between the driving disk 36 and the sliding block 28.

[0041] The functional principle of the utility model can be explained through the following operation modes:

[0042] The bottom plate 25 is placed on the mounting plate 30, and the driving shaft 35 is rotated to drive the driving disk 36 to rotate, and the driving disk 36 drives the traction rod 37 to deflect, and the traction rod 37 pulls the sliding block 28 to move horizontally in the sliding groove 27, and the sliding block 28 drives the limiting plate 33 to enter the limiting hole 34 in the fixing plate 32, so as to realize the installation operation of the ventilation duct bracket;

[0043] The ventilation duct 26 is placed on the support plate 20 on the surface of the bottom plate 25, and the rotating shaft 4 is driven by the turntable 5 to rotate. On the one hand, the primary screw 2 can be driven to rotate through the primary bevel gear set 3, and the moving block 7 drives the push cylinder 8 to extend and push the fixing member 10. The rotating plate 9 starts to rotate with the connection point of the fixing member 10 as the fulcrum, and the clamping device 13 is driven by the push rod 11 to move along the guide rod 15, so that the support plates 20 on both sides can abut against the two sides of the ventilation duct 26; on the other hand, the primary screw 2 can drive the secondary screw 23 to rotate through the secondary bevel gear set 24, so that the pressure plate 21 moves downward under the action of the secondary screw 23, so that the ventilation duct 26 is fixed by the support plate 20 in the vertical direction. When the support plates 20 on both sides abut against the ventilation duct 26, the pressure plate 2 The bottom support plate 20 does not abut against the ventilation duct 26. As the primary screw 2 continues to rotate, the clamping device 13 is driven to move further toward the ventilation duct 26. At this time, the angle between the hinge rods 19 is increased, driving the other end connecting plate 18 to deform the spring 17. Under the reaction of the spring 17, the support plates 20 on both sides can clamp the ventilation duct 26. With the pressure plate moving up and down, the device can fix ventilation ducts 26 of different sizes, thereby improving the stability of the device in fixing the ventilation duct 26. After the ventilation duct 26 is fixed, the abutting bolt 6 can be rotated to insert the other end of the abutting bolt 6 into the top plate 1 to fix the primary screw 2, thereby maintaining the device clamping the ventilation duct 26, thereby improving the installation stability of the ventilation duct 26.
