The limiting mechanism is installed on the top of the placement plate 13 for limiting the position of the clamping plate 16. The user puts the smoke exhaust equipment to be installed at a high place on the placement plate 13, and raises the placement plate 13 on the top of the telescopic rod 2 to the installation position by controlling the hydraulic device 4 inside the telescopic rod 2. The position is adjusted by the universal wheel 3 at the bottom of the base plate 1. There is no need for the installer to take the smoke exhaust equipment to be installed to a high place, which saves physical strength and makes the installation work safer.

[0025] Reference Figure 4 As shown, in the present embodiment: the fixing mechanism includes a limiting groove 7 opened on both sides of the splicing plate 6, the interior of the hollow box 5 is slidably connected with an L-shaped limiting plate 8, the outer side of the L-shaped limiting plate 8 is fixedly connected with a connecting rod 9, and the outer side of the connecting rod 9 is fixedly connected with a handle 10.

[0026] Reference Figure 5As shown, in this embodiment: the limiting mechanism includes a fixing plate 14 fixedly connected to the top of the placing plate 13, the number of the fixing plate 14 is two, and they are distributed on both sides of the top of the placing plate 13, and both sides of the top of the placing plate 13 are provided with sliding grooves 15, and the internal sliding grooves 15 are slidably connected with a clamping plate 16, and the internal threads of the fixing plate 14 are connected with a threaded rod 17. The user puts the smoke exhaust equipment to be installed in the middle of the clamping plate 16 above the placing plate 13, and rotates the threaded rod 17 to drive the clamping plate 16 to move toward the middle, clamping the smoke exhaust equipment to be installed to prevent the smoke exhaust equipment from falling off during the rising process of the smoke exhaust equipment. When the smoke exhaust equipment needs to be released after the installation is completed, the threaded rod 17 is rotated in the opposite direction to release the clamping of the smoke exhaust equipment.

[0027] Reference Figure 4 As shown, in the present implementation scheme: the inner wall of the hollow box 5 is fixedly connected with a round rod 11, a through hole 21 is opened on one side of the L-shaped limiting plate 8, and the user moves the handle 10 to drive the L-shaped limiting plate 8 to move, and when the hollow box 5 and the splicing plate 6 are fixed, the L-shaped limiting plate 8 moves on the surface of the round rod 11 through the limitation of the through hole 21, preventing the L-shaped limiting plate 8 from tilting and detaching from the inside of the limiting groove 7, resulting in unstable fixation.

[0028] Reference Figure 4 As shown, in the present implementation scheme: the inner wall of the L-shaped limit plate 8 is fixedly connected with a thrust spring 12, the user aligns the position of the notch of the splicing plate 6 with the hollow box 5, and moves the splicing plate 6 toward the direction of the hollow box 5. During the movement, the inner wall of the splicing plate 6 squeezes the L-shaped limit plate 8, so that the L-shaped limit plate 8 moves inward, and at the same time, the thrust spring 12 accumulates force. When the limit groove 7 opened on the splicing plate 6 moves to the top of the L-shaped limit plate 8, the thrust spring 12 pushes the L-shaped limit plate 8 to move to both sides and enter the interior of the limit groove 7, so that the hollow box 5 and the splicing plate 6 are fixed.

When the user rotates the threaded rod 17 to drive the splint 16 to move, the pulley 20 at the bottom of the splint 16 rotates inside the placement grooves 19, reducing the friction between the splint 16 and the slide groove 15, preventing the splint 16 from getting stuck during the movement, and reducing wear.

[0031] The working principle of the utility model is as follows: the user places the smoke exhaust equipment to be installed at a high place on the placement plate 13, raises the placement plate 13 on the top of the telescopic rod 2 to the installation position by controlling the hydraulic device 4 inside the telescopic rod 2, adjusts the position by the universal wheel 3 at the bottom of the bottom plate 1, aligns the splicing plate 6 with the position of the hollow box 5 and installs it, pulls the handle 10 to both sides, drives the L-shaped limit plate 8 to move to both sides, enters the inside of the limit groove 7, fixes the hollow box 5 and the splicing plate 6, and fixes the placement plate 13 on the top of the splicing plate 6 to the top of the telescopic rod 2, which is convenient for the user to splice the smoke exhaust equipment, moves the handle 10 inward, and brings The L-shaped limit plate 8 is moved out of the limit groove 7 to release the fixation of the hollow box 5 and the splicing plate 6 so that the splicing plate 6 can be removed, and the smoke exhaust equipment to be installed is placed in the middle of the clamping plate 16 above the placement plate 13, and the threaded rod 17 is rotated to drive the clamping plate 16 to move toward the middle to clamp the smoke exhaust equipment to be installed to prevent the smoke exhaust equipment from falling off during the rising process. When the smoke exhaust equipment needs to be released from the clamping of the smoke exhaust equipment after the installation is completed, the threaded rod 17 is rotated in the opposite direction to release the clamping of the smoke exhaust equipment, and the mobile handle 10 drives the L-shaped limit plate 8 to move. When the hollow box 5 and the splicing plate 6 are fixed, the L-shaped limit plate 8 is The limit of the through hole 21 moves on the surface of the round rod 11 to prevent the L-shaped limit plate 8 from tilting and disengaging from the limit groove 7. The position of the notch of the splicing plate 6 is aligned with the hollow box 5, and the splicing plate 6 is moved in the direction of the hollow box 5. During the movement, the inner wall of the splicing plate 6 squeezes the L-shaped limit plate 8, so that the L-shaped limit plate 8 moves inward, and at the same time, the thrust spring 12 accumulates force. When the limit groove 7 opened on the splicing plate 6 moves to the position of the top of the L-shaped limit plate 8, the thrust spring 12 pushes the L-shaped limit plate 8 to move to both sides and enter the interior of the limit groove 7, so that the hollow box 5 and the splicing plate 6 are fixed. The thrust of the spring 12 prevents the L-shaped limit plate 8 from moving inward during use of the equipment. After the smoke exhaust equipment is installed, the threaded rod 17 is rotated to release the limit on the clamp 16, and the clamp 16 is driven to move outward under the tension of the tension spring 18 to release the clamping of the smoke exhaust equipment. The hydraulic device 4 is controlled to retract, and the telescopic rod 2 is retracted to move the placement plate 13 downward to place other smoke exhaust equipment. In the process of rotating the threaded rod 17 to drive the clamp 16 to move, the pulley 20 at the bottom of the clamp 16 rotates inside the placement groove 19, reducing the friction between the clamp 16 and the slide groove 15, and preventing the clamp 16 from getting stuck during the movement.
