The assembly structure of the illuminating lamp 3 and the second longitudinal piece 25 is the same as the assembly structure of the illuminating lamp 3 and the first longitudinal piece 24, and will not be described one by one here.

[0035] The lamp holder 2 is located below the air jet holder 4, and the support tube 1 is provided with an outlet 102 penetrating the wire hole 11 below the lamp holder 2. A first wire is passed through the wire hole 11, and one end of the first wire passes through the outlet 102 and extends out of the support tube 1, and is connected to the lighting lamp 3. The assembly method of the first wire is not affected by the rotation of the driving member 5 and the air jet holder 4, nor will it affect the rotation of the driving member 5 and the air jet holder 4.

[0036] The support tube 1 is also provided with a slip ring seat 6, and a conductive slip ring assembly 7 is also provided on the slip ring seat 6. A terminal group 61 is provided on the outside of the slip ring seat 6, and a lead-out port 60 penetrating the inner cavity thereof is also provided on the outside of the slip ring seat 6; a second wire 701 led out from the lower end of the conductive slip ring assembly 7 is passed through the wire hole 11 or connected to the terminal group 61, and a rotatable third wire 702 is led out from the upper end of the conductive slip ring assembly 7, and the third wire 702 can be used to supply power to an external power-consuming structure that needs to rotate, so as to prevent the phenomenon of rotation winding and ensure the stability of power supply.

[0037] The conductive slip ring assembly 7 includes a shell 71 fixed in the inner cavity of the slip ring seat 6, an insulating seat 72 inserted in the shell 71, a central insulator 73 inserted in the insulating seat 72 and rotatable relative to the insulating seat 72, a plurality of metal conductive rings 74 arranged outside the central insulator 73, a metal elastic arm 75 fixed in the insulating seat 72 and elastically contacting the metal conductive ring 74, the third wire 702 is arranged in the central insulator 73 and electrically connected to the metal conductive ring 74, the second wire 701 is arranged in the insulating seat 72 and electrically connected to the metal elastic arm 75, the outer surface of the metal conductive ring 74 is provided with an arc groove 741, the end of the metal elastic arm 75 is provided with a spherical conductive surface 751, and the spherical conductive surface 751 is in contact with the arc groove 741.

The metal spring arm 75 is assembled and connected with the arc groove 741 on the outer surface of the metal conductive ring 74 by using a spherical conductive surface 751, which can ensure that the metal spring arm 75 is in contact with the metal conductive ring 74 at all times and the contact is stable, thereby ensuring the stability of power supply.

[0038] The insulating seat 72 and the central insulator 73 are assembled via two upper and lower shafts 70 to form a rotatable installation.

[0039] In summary, when the utility model is used, the support tube 1 is hoisted so that the illuminating lamp 3 and the air jet seat 4 are placed at the center of the cylindrical knitting machine. The illuminating lamp 3 illuminates the cylindrical knitting machine to realize the lighting function to meet the production needs. The illuminating lamp 3 can also realize the angle adjustment in the horizontal direction and the elevation angle, which is more convenient to use. At the same time, the rotating frame of the cylindrical knitting machine pushes the driving member 5 during the rotation process, thereby driving the air jet seat 4 to rotate relative to the support tube 1. The high-pressure gas enters through the air hole 12 of the support tube 1 and enters the annular air cavity 41 from the through hole 13 outside the support tube 1. Finally, it is ejected from the air jet hole 40 to the knitting position of the cylindrical knitting machine, and the cotton wool generated during knitting is blown outward to avoid falling into the fabric, thereby ensuring the quality of the fabric. Compared with the fan, the jet seat 4 is smaller in size and requires a smaller space, which can meet the use requirements of a small knitting machine. At the same time, it can also leave enough space for the installation and use of the lighting lamp 3. In addition, the high-pressure gas is sprayed through the jet seat 4, and its wind force is relatively large, which can blow away more cotton wool or thread ends that are difficult to move, and the cleaning effect is better.
