[0021] The working principle of the above technical scheme is as follows: in use, the user first installs the flange ring 4 at the hot air supply end, stretches the lengths of the telescopic inner cylinder 7 and the telescopic outer cylinder 6, inserts the flange plate 8 into the corresponding wall through the expansion screws, then installs the hoisting component through the mounting hole 19, fixes the support cylinder 1 at the use position, and then when the air flow needs to be adjusted, rotates the support ring 14 to drive the support rod 23 to rotate, drives one of the support plates 11 through the support rod 23, and rotates through the support plate 11, respectively transmits the rotating action through the first hinge rod 12 and the second hinge rod 13, and makes the first hinge rod 12 and the second hinge rod 13 rotate under the action of being hingedly connected to the hinge column 20, so that the other support plates 11 are pushed to rotate, thereby driving the rotating shaft 15 to rotate, and then making the baffle leaves 17 misaligned, and the wind flows through the misaligned baffle leaves 17 gap, and after being well fitted, the positioning hole 21 and the positioning groove 22 are inserted into the fixing pin inside to fix the telescopic inner cylinder 7 and the rotating shaft 15 after adjustment. This scheme is convenient for adjusting the size of the air flow passing through the support cylinder 1, thereby adjusting the size of the air flow, and is convenient for adjustment.

[0022] In another embodiment, as shown in Figure 1 and Figure 3 , the air holes 9 are uniformly distributed in a spiral thread inside the telescopic outer cylinder 6 and the telescopic inner cylinder 7.

[0023] Through the air holes 9 arranged, when the telescopic outer cylinder 6 and the telescopic inner cylinder 7 are stretched, the air holes 9 are released, one end of the flange plate 8 is blocked, and when the air flow is guided through the telescopic outer cylinder 6 and the telescopic inner cylinder 7, it is stably guided through the uniformly distributed air holes 9, so that the air flow is balanced, the air flow is balanced in the chamber under the guidance of the telescopic outer cylinder 6 and the telescopic inner cylinder 7, thereby balancing the hot air flow, evenly spraying hot air, and stabilizing the heat transfer efficiency and reducing the temperature difference.

[0024] In another embodiment, as shown in Figure 4 , the baffle leaves 17 are uniformly distributed on the outside of the flow guide column 16, and the opposite sides of the baffle leaves 17 have gaps.

[0025] The baffle leaves 17 block the inside of the support cylinder 1, and the outer edge of the baffle leaves 17 can be installed with a sleeved rubber edge to facilitate sealing and reduce air leakage. This design facilitates adjustment of the angle of the baffle leaves 17, thereby adjusting the air flow through the support cylinder 1 through the opening size, and is convenient to use.

[0026] In another embodiment, as shown in Figure 2 and Figure 4 , the two ends of the four first hinge rods 12 and the second hinge rods 13 are movably rotatably connected to the outside of the hinge column 20 through the hinge joints, and the four first hinge rods 12 and the second hinge rods 13 are circumferentially staggered and uniformly distributed on the outside of the support cylinder 1.

[0027] The balanced and staggered distribution of the first hinge rod 12 and the second hinge rod 13 facilitates the rotation of a support plate 11, which in turn causes the first hinge rod 12 and the second hinge rod 13 to push the rotation of multiple support plates 11, thereby causing the rotating shaft 15 to rotate. This allows for small-angle opening and closing adjustments, increasing ease of use.

[0028] In another implementation scheme, such as Figures 1-5 As shown, the positioning holes 21 are evenly distributed in a circle inside the support ring 14, and the positioning grooves 22 are evenly distributed in a circle on the outside of the protective shell 18. The positions of the positioning holes 21 and the positions of the positioning grooves 22 correspond to each other.

[0029] The positioning hole 21 and positioning groove 22 are inserted into the pin to fix the support ring 14 in the position of the protective shell 18, so that the adjusted support ring 14 is fixed and thus the adjusted position does not rotate, thereby making the structural adjustment stable and increasing the effect of use.

[0030] In another implementation scheme, such as Figures 1-5 As shown, the protective shell 18 is fixedly installed on the outside of the support cylinder 1, and the mounting holes 19 are evenly distributed in a circular pattern inside the flange ring 2 5 and flange ring 3 10.

[0031] The protective shell 18 provides protection for the support plate 11, the first hinge rod 12 and the second hinge rod 13. The mounting hole 19 can help the operator install the support cylinder 1 in a fixed position, which is convenient for use. The overall effect is good, which increases the convenience of use and installation. It can adapt to different installation positions and has a good overall performance.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
