[0031] The first lifting rod 201 is fixed to the supporting vertical rod 4. An active gear 203 is fixed inside the first lifting rod 201. The reduction gearbox 206 is fixed inside the first lifting rod 201. The reduction gearbox 206 is connected to the transmission rod 205.

A plurality of sliders are evenly clamped on the outside of the threaded seat 209. A plurality of guide rails are provided on the inner wall of the first lifting rod 201. Sliders are provided on all the plurality of guide rails. The sliders can only move along the corresponding guide rails. The upper end of the threaded seat 209 is connected to the bottom end of the second lifting rod 202. A flexible sealing ring 210 is provided on the inner wall of the top end of the first lifting rod 201. The first lifting rod 201 is in contact with the outer wall of the second lifting rod 202 through the flexible sealing ring 210, so as to prevent tobacco leaves from entering the inside of the lifting rod during operation, prevent the internal structure from being damaged by tobacco leaves or other external foreign objects when the lifting rod operates, and also prevent the lifting rod from damaging the tobacco leaves during operation;

[0032] The drive motor 207 serves as a power source to convert the electrical energy required for the movement of the lifting rod into mechanical energy; the transmission system converts the rotational motion of the motor into linear motion or realizes speed reduction and torque increase through the meshing of gears to meet the requirements of the lifting rod for thrust and speed; the guide rail system is used to guide the movement trajectory of the lifting rod to ensure that the lifting rod remains stable and accurate during the lifting process; the lifting rod body includes multiple coaxial rods, and the lifting function is realized through mechanical connection. Under the coordinated action of the guide rail and the gear, the lifting rod body can achieve precise lifting;

[0033] The guide rail lifting rod 2 remains stable and accurate during the lifting process through the coordinated action of the guide rail and the gear, avoiding shaking and deviation; through the speed reduction and torque increase function of the gear transmission system, the lifting rod can obtain greater thrust and load-bearing capacity, suitable for various load requirements; the guide rail lifting rod 2 has the advantages of good stability and strong load-bearing capacity, and can be applied to various places requiring precise control and stable movement, with wide applications;

[0034] When the drive motor 207 receives the control signal sent by the electronic control box 6, it starts to rotate and output power. The rotational motion of the drive motor 207 is transmitted to the guide rail system through the transmission system. The active gear 203 drives the passive gear, thereby driving the lead screw to rotate clockwise or counterclockwise. The outer wall of the lead screw is threadedly connected to a threaded seat 209. The upper end of the threaded seat 209 is fixed with a second lifting rod 202, and the slider fixed to the outer wall of the threaded seat 209 moves up and down along the guide rail provided on the inner wall of the first lifting rod 201. Thus, it can drive the second lifting rod 202 to move vertically upward or downward along the inner wall of the first lifting rod 201, thereby completing the adjustment of the height of the electric lifting rod. During this process, the meshing effect of the gears realizes speed reduction and torque increase, enabling the lifting rod to obtain sufficient thrust and a stable movement speed. The guide rail system ensures that the lifting rod moves along a predetermined trajectory during the lifting process. Through the guidance of the guide rail, the stable lifting of the guide rail lifting rod 2 is achieved. Under the combined action of the drive motor 207, the gears, and the guide rail, the lifting rod body realizes the lifting action.

[0035] According to Figure 3 As shown, the telescopic support rod 1 includes a base 101, a drive system, a telescopic system, a transmission system, and a control system.

When the multiple coaxial telescopic rod members 104 are arranged, the coaxial telescopic rod member with a larger diameter is closer to the base 101. One end of the coaxial telescopic rod member with the largest diameter is installed on the base 101. Except for the coaxial telescopic rod member with the largest diameter, the distances from the other coaxial telescopic rod members to the base 101 increase in an arithmetic progression.

The thickness of the T-shaped member 105 does not need to be adapted to this distance, and a piston piston sleeve can be installed under the T-shaped member 105 for buffering;

[0038] The telescopic lead screw is arranged inside the multiple coaxial telescopic rod members 104 and is connected to the transmission system. The telescopic lead screw includes a driving lead screw 102 and multiple driven lead screws 103. The driving lead screw 102 is in transmission connection with the transmission mechanism.

[0040] A multi - section coaxial telescopic rod member 104 is relatively installed, and a sealing ring sleeve 109 is sleeved on the other end of the guiding slider 1052. A second circumferential guiding structure is provided between the sealing ring sleeve 109 and the multi - section coaxial telescopic rod member 104.

And through the second circumferential guiding structure, the sealing ring sleeve 109 is restricted between the sealing ring sleeve 109 and the multi - section coaxial telescopic rod member 104, improving the stability of the dust - proof cover sealing ring sleeve 109 during the rising process; The second circumferential guiding structure includes a plurality of guiding pieces 110.

[0041] The first synchronization mechanism includes a first linkage sleeve 106. The active lead screw 102 and the passive lead screw 103 are connected through the first synchronization mechanism. The first linkage sleeve 106 is fixedly installed at the end of the active lead screw 102 away from the transmission mechanism. The first linkage sleeve 106 is circumferentially provided with spaced first linkage teeth. The inner part of the passive lead screw 103 closest to the active lead screw 102 is provided with a first circumferential linkage groove adapted to the outer shape of the first linkage sleeve 106;

[0042] The second synchronization mechanism includes a linkage block. The adjacent passive lead screws 103 are connected through the second synchronization mechanism.

[0043] By fixedly installing a linkage block 108 linked to the driving lead screw 102 at the head of the driving lead screw 102, the linkage block 108 can be sleeved outside the driving lead screw 102 and fixedly connected to the head of the driving lead screw 102 at one end. The driven lead screw 103 closest to the driving lead screw 102 is linked with the linkage teeth through a first circumferential linkage groove, so that when the driving lead screw 102 rotates, it drives the driven lead screw 103 to rotate at the same time; a first circumferential linkage groove is arranged inside each driven lead screw 103. Since the diameters of the driven lead screws 103 are different and they are sleeved together one by one, the diameter of the first circumferential linkage groove also changes with the inner diameter of the driven lead screw 103. Correspondingly, in order to adapt to the inner diameters of the driven lead screws 103, the sizes of the linkage block 108 and the second linkage sleeve 107 also adapt accordingly. The driven lead screws 103 achieve synchronous rotation through the first circumferential linkage groove, the linkage block 108 and the second linkage sleeve 107;

[0044] The drive system drives the driving lead screw 102 and the driven lead screw 103 to rotate synchronously through the drive transmission mechanism, so as to prompt the T-shaped part 105 to drive the coaxial multi-tube segments to lift and lower synchronously.

[0046] The telescopic support rod 1 adopts a multi-section design, and the telescopic system can adjust the telescopic length as needed. Through the control system, the telescopic degree and speed of the telescopic system can be conveniently controlled to achieve precise positioning. The telescopic system maintains good stability during the telescopic process, is not easy to shake or tilt, and ensures the safety and reliability of use;

[0047] When the control system receives the control signal sent by the electric control box 6, it controls the motor to start rotating and output power. The rotational motion of the motor is converted into the linear motion of the telescopic system through the transmission system, so as to drive the telescopic part to expand and contract. Through the precise control of the control system, it can be ensured that a plurality of coaxial rod members and telescopic rods maintain synchronous motion during the telescopic process, reaching the required length and position.

[0048] The handrail 5 is arranged on the support vertical rod 4, and the electric control box 6 is arranged on the handrail 5.

[0049] When the utility model is in use, first place multiple stacks of bundled tobacco on the telescopic support rod as needed.
