[0022] The inner built-in warehouse 21 is arranged in the vertical rod 2 to accommodate the lead screw 22, so that the lead screw 22 can rotate in the vertical rod 2 to provide power for the subsequent component linkage. One end of the lead screw 22 has a lead screw shaft 221 connected to one end of the lead screw 22 and the motor, which is located in the support seat 25. The support seat 25 is fixed to the bottom of the inner built-in warehouse 21 by the support block 26, which ensures that the lead screw 22 is upright and can be driven by the motor in the motor compartment 5. The outer side of the lead screw 22 is sleeved with a threaded sleeve 23, and the threaded sleeve 23 is connected with the limiting sleeve 3. The number of the limiting sleeve 3 can be added as needed to facilitate lifting and carrying different number of objects. The threaded sleeve 23 cooperates with the limiting sleeve 3. The rotation of the lead screw 22 should drive the threaded sleeve 23 to rotate synchronously. However, due to the limiting of the sliding groove 7 on the vertical rod 2, the threaded sleeve 23 can only be fixed and displaced up and down by the thread. The fixed plate 24 on the threaded sleeve 23 connects the limiting sleeve 3 to ensure stable linkage. The control box 8 at the bottom of the vertical rod 2 drives the motor compartment 5 at the top. The motor drives the lead screw 22 to rotate and drive the components to operate, so that the moving connecting plate 4 carries the objects up and down.

[0023] Please refer to Figure 3The top of the vertical rod 2 is provided with a top connecting piece 6, which is used for fixing the top of the vertical rod 2, so as to prevent the vertical rod 2 from deviating during operation. The bottom of the vertical rod 2 is provided with a base 1, which is used for expanding the contact area of the vertical rod 2 on the ground. The base 1 supports the vertical rod 2. The base 1 and the top connecting piece 6 fix the two ends of the vertical rod 2. The base 1 is mainly used for reducing the possibility of the vertical rod 2 falling down, and the top connecting piece 6 completely fixes the vertical rod 2. The top connecting piece 6 comprises a bottom connecting plate 62 used for connecting with the vertical rod 2. The bottom connecting plate 62 is bolted with the top of the vertical rod 2. The connecting claw 61 is used for connecting the bottom connecting plate 62 and the top connecting plate 63. The connecting claw 61 is also used for connecting the bottom connecting plate 62 to the middle section of the vertical rod 2 and extending downward. The bottom connecting plate 62 is provided with the connecting claw 61. The connecting claw 61 is connected with the top connecting plate 63. The top connecting plate 63 is used for bearing two connecting claws 61. The top connecting plate 63 is provided with a connecting rod 64, which is used for connecting with the fixing device of the top, so as to stabilize the connection of the vertical rod 2.

[0024] When the screw rod type lifting machine is used, the vertical rod 2 is in a core position. An inner built-in bin 21 is arranged in the vertical rod 2, which is used for accommodating a screw rod 22, so as to ensure that the screw rod 22 can rotate freely in the vertical rod 2, thereby driving the subsequent components to operate. One end of the screw rod 22 is provided with a screw rod rotating shaft 221. The screw rod rotating shaft 221 is connected to the other end of the screw rod 22 connected with a motor. The screw rod rotating shaft 221 is arranged in a supporting seat 25. The supporting seat 25 is arranged in the inner built-in bin 21. The bottom is stably supported by a supporting block 26. The screw rod rotating shaft 221 is effectively prevented from deviating. The screw rod 22 is always straight and can be driven to rotate by the motor in the motor bin 5. The outer side of the screw rod 22 is sleeved with a threaded sleeve 23. The outer side of the threaded sleeve 23 is connected with the inner side of the limiting sliding sleeve 3. At the same time, the fixed plate 24 on the threaded sleeve 23 further tightly connects the threaded sleeve 23 and the limiting sliding sleeve 3. When the screw rod 22 rotates, the threaded sleeve 23 should be driven to rotate synchronously. However, due to the limiting effect of the sliding groove 7 on the vertical rod 2, the threaded sleeve 23 can only be fixed and moved up and down according to the threaded drive. On the layout of the outer side of the vertical rod 2, the bottom is provided with a control box 8, and the top is provided with a motor bin 5. The control box 8 is used for driving the motor bin 5. The motor in the motor bin 5 drives the screw rod 22 to rotate, thereby driving the limiting sliding sleeve 3 closely connected with the threaded sleeve 23 to move up and down along the vertical rod 2. The limiting sliding sleeve 3 is connected with the moving connecting plate 4. Finally, the moving connecting plate 4 realizes the up and down carrying function of the object.
