[0019] Compared with the prior art, the beneficial effects of this utility model are: This telescopic and controllable stable vertical lifting device allows for easy adjustment of the clamping and wrapping distance during use, making it easy to adjust the clamping and wrapping distance according to the size of the object being lifted, thus avoiding any impact on the clamping and wrapping efficiency and improving the versatility of the device. Furthermore, it facilitates quick disassembly and assembly when the device is damaged, allowing operators to easily inspect and replace damaged parts, improving the maintenance and repair efficiency of the device, and resulting in a better overall performance. Specific details are as follows:
[0020] 1. The extension length of the connecting frame is limited and adjusted by the second limiting rod in conjunction with the second guide rod, so that the operator can easily adjust the support length of the second guide rod and the connecting frame according to the size of the object being lifted, so as to avoid affecting the clamping and wrapping efficiency of the device and improve the versatility of the device.
[0021] 2. The drive motor, in conjunction with the first drive disc, pushes the drive rod and the second drive disc to rotate inside the support frame.

At this time, the connecting block, in conjunction with the connecting frame connected to its lower end, clamps and limits the suspended object, improving the hoisting stability of the device and preventing the suspended object from falling off due to unstable clamping during upward displacement.
[0022] 3. By rotating the third limit rod outward, the third limit rod relaxes its series limit on the locking block and the limit plate, making it easier for the operator to pull out the limit plate. At this time, the limit plate relaxes its series limit on the connecting plate and the support frame, making it easier for maintenance personnel to replace and repair damaged parts inside the support frame.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Please see Figure 1-6 This utility model provides a technical solution: a telescopic and controllable stable vertical lifting device, including a support frame 1, a positioning block 2, a lifting ring 3, a first limiting rod 4, a drive motor 5, a first drive disc 6, a drive rod 7, a second drive disc 8, a connecting block 9, a first guide rod 10, a first anti-slip pad 11, a second guide rod 12, a connecting frame 13, a guide block 14, a preset hole 15, a second limiting rod 16, a second anti-slip pad 17, a connecting plate 18, a limiting plate 19, a third limiting rod 20, a locking block 21, and an O-ring 22.
[0032] Specifically, such as Figure 3 , Figure 4 and Figure 5As shown, before using the device, the engaging connection between the lifting ring 3 and the positioning block 2 allows the operator to easily install the lifting ring 3 on the upper side of the positioning block 2. At this time, the first limiting rod 4, which passes through the outer side of the lifting ring 3, is rotated. Due to the threaded connection between the first limiting rod 4 and the lifting ring 3 and the support frame 1, the downward rotation of the first limiting rod 4 effectively connects the lifting ring 3 and the support frame 1 together. The lifting rope is then passed through the inside of the lifting ring 3. The second limiting rod 16 is then rotated outwards. Due to the threaded connection between the second limiting rod 16 and the second guide rod 12 and the connecting frame 13, the outward rotation of the second limiting rod 16 loosens its connection to the second guide rod 12 and the connecting frame 13. The series limiting mechanism of the frame 13 facilitates the operator's downward pulling of the connecting frame 13. Due to the sliding connection structure between the connecting frame 13, guide block 14, and second guide rod 12, the downward-moving connecting frame 13 is guided by the second guide rod 12 and guide block 14, preventing positional displacement during downward movement. Upon reaching the designated position, the second limiting rod 16 is pushed inward, causing it to re-enter the preset hole 15. Rotating the second limiting rod 16, which passes through the preset hole 15, reconnects it to the second guide rod 12 and connecting frame 13, thus adjusting the extension / retraction length of the second guide rod 12 and connecting frame 13. In this process, the device is placed outside the suspended object, and the drive motor 5 inside the support frame 1 is activated. The drive motor 5 drives the first drive disc 6 connected to its lower side to rotate inside the support frame 1. Due to the meshing connection between the first drive disc 6 and the second drive disc 8, the first drive disc 6 can effectively push the drive rod 7 and the second drive disc 8 to rotate inside the support frame 1 during rotation. Furthermore, due to the threaded connection between the drive rod 7 and the connecting block 9, the rapidly rotating drive rod 7 can effectively push the connecting block 9 connected to its outer side to move inward. And because the drive rod 7 has opposing threaded structures on its left and right sides, it can easily push the connecting block 9 on both sides... The connecting block 9 moves inward synchronously. At this time, due to the sliding connection structure between the connecting block 9 and the first guide rod 10, the connecting block 9 moving inward is guided and limited by the first guide rod 10, which prevents the connecting block 9 from shifting position during the inward movement. At this time, the connecting block 9, together with the connecting frame 13, clamps and limits the suspended object inside it, so that the first anti-slip pad 11 and the second anti-slip pad 17 fill the gap between the suspended object and the connecting frame 13 and the connecting block 9, preventing the suspended object from falling off due to insufficient friction during the upward movement of the hoisting. This completes the telescopic adjustment of the device, improves the clamping and installation efficiency of the device, and improves the versatility of the device.
[0033] Specifically, such as Figure 1 , Figure 2 and Figure 6 As shown, after the device is used, the third limiting rod 20, which passes through the middle of the limiting plate 19, is rotated. Due to the threaded connection between the third limiting rod 20, the limiting plate 19, and the locking block 21, the upward-rotating third limiting rod 20 relaxes its series limiting effect on the limiting plate 19 and the locking block 21. This allows the operator to pull out the limiting plate 19 and the third limiting rod 20, making it easier for the operator to separate and disassemble the support frame 1 and the connecting plate 18. At this time, maintenance personnel can easily replace and repair any damaged parts inside the support frame 1, improving the maintenance efficiency of the device and reducing the maintenance cost. Simultaneously, a brand-new support frame 1 is reinstalled on both the front and rear sides of the connecting plate 18, and the limiting plate 19 is then reinstalled. On the outside of the connecting plate 18, due to the engaging connection structure between the limiting plate 19, the connecting plate 18, and the support frame 1, the limiting plate 19 can effectively limit the support frame 1 and the connecting plate 18 in series. At this time, the locking block 21 and the O-ring 22 are installed on the lower side of the limiting plate 19. At the same time, the third limiting rod 20 passing through the middle of the limiting plate 19 is rotated, so that the downward rotating third limiting rod 20 can effectively connect the limiting plate 19 and the locking block 21 in series. At this time, the O-ring 22 that fits in the gap between the locking block 21 and the limiting plate 19 fills the gap between the locking block 21 and the limiting plate 19, so as to avoid the structural stability of the connection between the third limiting rod 20 and the locking block 21 due to vibration during the use of the device, and improve the strength of the device.
