[0025] like Figure 2 and Figure 4As shown, the positioning assembly 401 includes a threaded mounting frame 4011, a screw 4012, a connecting plate 4013 and a fixed bracket 4014. The threaded mounting frame 4011 is fixedly connected to the circumferential surface of the mounting ring 7, the screw 4012 is threadedly connected to the inner wall of the threaded mounting frame 4011, the connecting plate 4013 is rotatably connected to the circumferential surface of the screw 4012, the fixed bracket 4014 is fixedly connected to the side end of the connecting plate 4013, the surface of the hose 3 is in contact with the inner wall of the fixed bracket 4014, and the fixed bracket 4014 is elastic and can be used to fix the hose 3 and the upper The air filter 8 on the side is fixed to prevent the hose 3 from being scattered. At the same time, the screw 4012 is rotated. The screw 4012 moves into the threaded mounting frame 4011 through the thread, which can drive the connecting plate 4013 and the fixed bracket 4014 to move, and the storage position of the hose 3 is moved. The rotating direction and position of the mounting ring 7 on the surface of the filter body 1 can be changed to fit the complex placement environment on the table, which is convenient for use. The stabilizing component 402 includes a stabilizing plate 4021 and a connecting block 4023. The side end of the connecting plate 4013 is fixedly connected There is a stabilizing plate 4021, and a connecting piece 4022 is fixedly connected to the side end of the stabilizing plate 4021. A sliding hole 4024 is opened at the side end of the threaded mounting frame 4011. The connecting block 4023 slides with the inner wall of the sliding hole 4024. When the screw 4012 rotates to drive the connecting plate 4013 and the fixed bracket 4014 to move, the connecting plate 4013 is easy to rotate and shake with the rotation of the screw 4012. The stabilizing plate 4021 is connected to the connecting block 4023, and the connecting block 4023 slides with the sliding hole 4024, so that the connecting plate 4013 will not shake when moving and is more stable. The stabilizing component 402 also includes a connecting piece 4022, which is rotatably connected to the circumferential surface of the screw 4012. The side end of the connecting piece 4022 is fixedly connected to the connecting block 4023.

At the same time, the connecting piece 4022 and the connecting block 4023 are fixed to form a whole, which can support the screw 4012 and reduce the probability of the screw 4012 being damaged by gravity.

[0026] like Figure 2 and Figure 3As shown, the support mechanism 6 includes an expansion component 601 and two sets of limit components 602. The expansion component 601 includes a mounting seat 6011, a bidirectional lead screw 6012, two rectangular nuts 6013 and a fitting roller 6014. The mounting seat 6011 is fixedly connected to the side end of the "L"-shaped mounting plate 5. The inner wall of the mounting seat 6011 is rotatably connected with the bidirectional lead screw 6012. The two rectangular nuts 6013 are both threadedly connected to the circumferential surface of the bidirectional lead screw 6012. The two fitting rollers 6014 are respectively fixedly connected to the two rectangular nuts 6013. The two fitting rollers 6014 contact the surface of the fitting hose 3. When the device is in use, the lower side of the hose 3 is prolapsed. The two ends of the bidirectional lead screw 6012 have two threads in opposite directions. When the bidirectional lead screw 6012 rotates, the two rectangular nuts 6013 can move closer to or farther from each other. The length of the bidirectional lead screw 6012 is slightly greater than the maximum moving distance of the fitting roller 6014, which can block one side of the hose 3 to prevent the hose 3 from detaching. The expansion assembly 601 The device also includes a rotating wheel 6015, which is fixedly connected to the circumferential surface of the bidirectional lead screw 6012. A mounting hole 6016 is provided at the upper end of the mounting seat 6011. The rotating wheel 6015 is arranged in the mounting hole 6016. The bidirectional lead screw 6012 can be driven at the center through the rotating wheel 6015, thereby reducing the overall length of the device and reducing space. The two sets of limiting components 602 each include a limiting plate 6021 fixedly connected to the side end of the mounting seat 6011. One end of the limiting plate 6021 movably passes through the side end of the rectangular nut 6013 and extends outward to overlap with one end of the bidirectional lead screw 6012. When the bidirectional lead screw 6012 rotates, the rectangular nut 601 3 is easy to shake with the rotation of the two-way screw 6012, and it is difficult to stably fit the hose 3. The sliding of the rectangular nut 6013 is limited by the limiting plate 6021, so that the rectangular nut 6013 is more stable when sliding and is not easy to shake or tilt. The limiting component 602 also includes a rotating seat 6022, which is rotatably connected to the circumferential surface of the two-way screw 6012. The upper end of the rotating seat 6022 is fixedly connected to the limiting plate 6021. When the two-way screw 6012 rotates, the two ends are easy to swing. The rotation of the two-way screw 6012 is limited by the rotating seat 6022, so that when the two-way screw 6012 rotates, it is not easy to swing.

[0027] Working principle: When the hose 3 needs to be stored to prevent it from being scattered, first insert the circumferential surface of the hose 3 close to the air filter 8 into the fixed bracket 4014, and then rotate the screw 4012. The screw 4012 moves into the threaded mounting frame 4011 through the thread, which can drive the connecting plate 4013 and the fixed bracket 4014 to move, and move the storage position of the hose 3. The storage direction and position are changed by rotating the mounting ring 7 on the surface of the filter body 1, which can fit the complex placement environment on the table, and is convenient During use, when the storage position is well positioned, the prolapsed portion on the lower side of the hose 3 is easily pressed down by gravity and easily folded and damaged. At this time, by rotating the two-way screw 6012, the two-way screw 6012 drives the two rectangular nuts 6013 to move away from each other, and the rectangular nut 6013 pushes the fitting roller 6014 to prop up the hose 3, so that the prolapsed portion on the lower side of the hose 3 has a larger angle and is not easy to be folded and damaged. At this time, the hose 3 is positioned for storage and will not be scattered, which is convenient for use. At the same time, after storage, the hose 3 will not be excessively deflected and damaged.

[0028] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
