[0040] like Figure 1 , 3 As shown, in an optional embodiment of the present invention, a first slide rail 39 is fixedly connected to the inner wall of the transmission cavity 3, and the displacement seat 28 is slidably connected to the first slide rail 39.

[0041] like Figure 1 , 3 As shown, in an optional embodiment of the present invention, a second slide rail 40 is fixedly connected to the inner wall of the transmission cavity 3, and the slider 12 and the second electrical connector 9 are both slidably connected to the second slide rail 40.

[0042] like Figure 3 , 6 As shown, in an optional embodiment of the present invention, a friction layer 26 is fixedly attached to the active cylinder 25. The friction layer 26 can increase the friction between the active cylinder 25 and the lamp tube body 35, making it easier for the active cylinder 25 to drive the lamp tube body 35 to rotate.

[0043] In an optional embodiment of the invention, the friction layer 26 is a methyl silicone sleeve.

[0044] Methyl silicone is a silicone-based polymer material with silicon-oxygen bonds as the main chain and methyl groups in the side chains. It not only improves friction but also has the following advantages:

[0045] It has excellent resistance to high and low temperatures and can work stably in a temperature range of -60℃ to 200℃ without becoming brittle or melting.

[0046] Excellent aging resistance, and resistance to ultraviolet rays, ozone and oxidation;

[0047] It has excellent electrical insulation properties, making it suitable for use as an insulating material in electronic equipment.

[0048] In an optional embodiment of the invention, the friction layer 26 is a styrene-butadiene rubber sleeve.

[0049] Styrene-butadiene rubber (SBR) is a synthetic rubber copolymerized from butadiene and styrene. It not only improves friction but also offers the following advantages:

[0050] Excellent wear resistance; styrene-butadiene rubber has high wear resistance and a long service life.

[0051] With relatively low cost, raw material prices and production costs are lower than those of natural rubber, making it one of the most economical and efficient rubber materials.

[0052] It has good electrical insulation properties and is suitable for insulating components in electronic equipment.

[0053] In an optional embodiment of the present invention, the connector body 1 is made of polycarbonate.

[0054] According to an optional embodiment of the present invention, the method for manufacturing the connector body 1 includes: placing polycarbonate granules into an injection molding machine, heating and melting them in the injection molding machine, injecting the molten polycarbonate into a mold, and turning on the cooling system in the mold to cool the formed connector body 1.

[0055] Implementation process:

[0056] The lamp tube body 35 has a first plug 36 on the left end and a second plug 37 on the right end.

[0057] In the initial state, the lamp tube body 35 abuts against the first groove 23 on the movable glass support 21, and the lamp tube body 35 abuts against the second groove 24 on the fixed glass support 22. That is, the movable glass support 21 and the fixed glass support 22 support the lamp tube body 35. The first plug 36 extends into the first electrical connection groove 7 and abuts against the first electrical connection piece 8. The second plug 37 extends into the second electrical connection groove 10 and abuts against the second electrical connection piece 11. Since both the first electrical connection piece 8 and the second electrical connection piece 11 are electrically connected to the power supply, the power supply can provide power to the lamp tube body 35, so that the lamp tube body 35 emits light to provide illumination for the user. The active tube 25 abuts against the lamp tube body 35.

[0058] When the lamp body 35 needs to be replaced, the motor 33 is turned on. The rotor of the motor 33 rotates, and after being reduced by the reducer 34, the rotor drives the threaded rod 31, the second spur gear 32, the first spur gear 30, the rotating rod 27, and the drive cylinder 25 to rotate. The threaded rod 31 is threadedly connected to the inner wall of the threaded hole 14, thereby driving the slider 12, the first elastic element 13, and the second electrical connector 9 to move to the right. The second plug 37 disengages from the second electrical connection slot 10. First, the first permanent magnet 15 moves to the front of the second permanent magnet 29, and the second permanent magnet 29... The magnetic repulsion of the first permanent magnet 15 overcomes the elastic force of the third elastic element 38 and moves backward, thereby releasing the friction layer 26 on the active cylinder 25 from its contact with the lamp tube body 35. When the push wheel 17 moves to contact the wedge plate 18, the push wheel 17 continues to move to the right, which will push the wedge plate 18, the linkage glass rod 20, and the movable glass support 21 to move forward against the elastic force of the second elastic element 19, thereby releasing the movable glass support 21 from supporting the lamp tube body 35. The lamp tube body 35 will fall down, and the user can catch it with their hand under the lamp tube body 35 in advance.

[0059] The reverse motor 33 reverses the rotation of the threaded rod 31, the second spur gear 32, the first spur gear 30, the rotating rod 27, and the drive cylinder 25. The slider 12, the first elastic element 13, and the second electrical connector 9 move to the left. When the push wheel 17 disengages from the wedge plate 18, the wedge plate 18 moves backward and resets under the elastic force of the second elastic element 19, causing the movable glass support 21 to move backward. The motor 33 stops running. The user places the new lamp tube 35 on the first support slot 23 and the second support slot 24 for support. The motor 33 continues to run, and the slider 12 and the second electrical connector 9 continue to move to the left. When the first permanent magnet 15 moves to the left of the second permanent magnet 29, the second permanent magnet 29 loses the magnetic repulsion of the first permanent magnet 15. The drive cylinder 25 and the displacement seat 28 move forward and reset under the elastic force of the third elastic element 38. The friction layer 26 on the drive cylinder 25 and the new lamp tube 35... 5. The outer walls abut together, then the second plug 37 and the left wall of the second electrical connector 9 abut together. The slider 12 continues to move to the left, compressing the first elastic element 13. The second electrical connector 9 pushes the lamp tube body 35 so that the first plug 36 and the right wall of the first electrical connector 6 abut together. When the friction layer 26 on the active cylinder 25 rotates, the friction of the friction layer 26 will drive the lamp tube body 35 to rotate, so that the first plug 36 on the lamp tube body 35 is aligned with the first electrical connection groove 7, and the second plug 37 is aligned with the second electrical connection groove 10. Under the elastic force of the first elastic element 13, the second electrical connector 9 moves to the left, so that the second plug 37 is inserted into the second electrical connection groove 10 and abuts against the second electrical connection piece 11. The second electrical connector 9 pushes the lamp tube body 35 to the left, so that the first plug 36 is inserted into the first electrical connection groove 7. The first plug 36 and the first electrical connection piece 8 abut together, completing the electrical connection.

[0060] When replacing the lamp body 35, this invention eliminates the need for manual rotation of the lamp body 35. The movable glass support 21 moves automatically with the drive of the motor 33, causing the lamp body 35 to fall and automatically disconnect from the electrical connection. The movable glass support 21 then resets with the drive of the motor 33 again. The user simply places the lamp body 35 into the first groove 23 on the movable glass support 21 and the second groove 24 on the fixed glass support 22. The motor 33 automatically rotates the lamp body 35, adjusting its position via the active cylinder 25 and the friction layer 26, eliminating the need for manual alignment. This automatically completes the electrical connection between the first plug 36 and the second plug 37. Throughout the replacement process, the user does not need to touch the lamp body 35, which remains electrically connected, thus improving the efficiency and safety of lamp body replacement.
