Description

Technical Field

[0001] This invention relates to the field of power socket technology, and in particular to a hoisting and lifting socket. Background Technology

[0002] In real life, because the sockets in the room are fixed to the wall, the cables of some large equipment are not long enough. Connecting them with power strips will make the room messy and inconvenient to use electricity. For example, it is inconvenient to install sockets on the ground in relatively spacious laboratories or factories, and installing sockets on the ground will reduce the usable space in the room.

[0003] Therefore, existing technologies still need to be improved and enhanced. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a suspended lifting socket, which aims to solve the problems of inconvenient power supply of fixed sockets on the wall and reduced indoor space utilization caused by connecting them with power strips.

The two first side plates are located on opposite sides of the crossbeam. Along the length of the crossbeam, several fourth pivots are arranged in two rows at both ends of the first base plate, and the bottom end of each fourth pivot is fixedly mounted on the side of the first base plate closest to the crossbeam. Each fourth pivot has a first roller, and the side of each first roller closest to the crossbeam is located within guide rails on both sides of the crossbeam.

[0028] When the first sliding frame slides toward the fifth fixed bracket, it collides with the second micro switch and then stops moving.

[0029] As a further improvement, the aforementioned hoisting and lifting socket also includes:

[0030] The tensioner includes a U-shaped bracket and an adjusting screw. One end of the U-shaped bracket with an opening is clamped to the end of the crossbeam away from the first fixed bracket, and the second fixed bracket is disposed inside the U-shaped bracket. A gap is left between the end of the second fixed bracket away from the first fixed bracket and the end of the U-shaped bracket away from the fixed bracket.

Detailed Implementation

[0056] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0057] Example:

[0058] Please see Figures 1-19The hoisting and lifting socket 7 includes: a horizontal frame 1, with guide rails 2 on both sides of the horizontal frame 1 along its length, and connecting plates 3 at both ends of the horizontal frame 1 for fixing the horizontal frame 1; a first sliding frame 4, which is disposed on one end of the horizontal frame 1 and slides to the other end of the horizontal frame 1 via the guide rails 2, with a first rotating shaft 401 on the first sliding frame 4 and a fixed pulley 402 on the first rotating shaft 401; and a first fixed bracket 5, which is disposed on the horizontal frame 1 away from the first sliding frame 1. The end of the frame 4; cable 6 and socket 7, one end of the cable 6 is fixedly mounted on the cross frame 1, and one end of the cable 6 is located between the first sliding frame 4 and the first fixed bracket 5, the other end of the cable 6 passes around the fixed pulley 402 and is suspended on the first fixed bracket 5, and the other end of the cable 6 is electrically connected to the socket 7, and the socket 7 is suspended on the first fixed bracket 5 through the cable 6; power supply module 8, the power supply module 8 is mounted on the cross frame 1 and is electrically connected to the end of the cable 6 away from the socket 7.

[0059] like Figures 1-7As shown, in this embodiment, the hoisting and lifting socket 7 includes a horizontal frame 1, a first sliding frame 4, a first fixed bracket 5, a cable 6, a socket 7, and a power supply module 8. Along the length of the horizontal frame 1, connecting plates 3 are respectively provided at the top of the front and rear ends of the horizontal frame 1. Guide rails 2 are respectively provided on the left and right sides of the horizontal frame 1. The connecting plates 3 are used to fix the horizontal frame 1. For example, by using screws to pass through the connecting plates 3 and the ceiling, the connecting plates 3 are detachably connected to the ceiling, thereby achieving the suspension of the horizontal frame 1. The first sliding frame 4 is movably mounted on the horizontal frame 1 via the guide rails 2, and the initial position of the first sliding frame 4 is located at the rear end of the horizontal frame 1. The first fixed bracket 5 is located at the front end of the horizontal frame 1, meaning the first sliding frame 4 can slide towards the first fixed bracket 5 on the guide rails 2. The first sliding frame 4 is also provided with a first rotating shaft 401 and a fixed pulley 402. The fixed pulley 402 is mounted on the first rotating shaft 401 and the fixed pulley 402 is mounted on the first rotating shaft 401. The wheel 402 can roll on the first rotating shaft 401. The first rotating shaft 401 and the fixed pulley 402 are both located above the top of the cross frame 1. One end of the cable 6 is pressed and fixed on the cross frame 1 by a buckle plate 35, and one end of the cable 6 is located between the first sliding frame 4 and the first fixed bracket 5. There are two buckle plates 35. The other end of the cable 6 passes around the fixed pulley 402 and is suspended on the first fixed bracket 5. Since the fixed pulley 402 can rotate on the first rotating shaft 401, the friction between the fixed pulley 402 and the cable 6 can be reduced. In this embodiment, the end of the cable 6 fixed on the cross frame 1 is named the lower end of the cable 6, and the end of the cable 6 suspended on the first fixed bracket 5 is named the upper end of the cable 6. The lower end of the cable 6 is close to the first fixed bracket 5, and the upper end of the cable 6 is electrically connected to the socket 7. The power supply module 8 is set on the cross frame 1 and electrically connected to the lower end of the cable 6. The power supply module 8 is used to supply power to the socket 7. When the first sliding frame 4 is pushed from the initial position toward the front end of the cross frame 1, the fixed pulley 402 moves along with the first sliding frame 4 toward the front end of the cross frame 1. At this time, the socket 7, under its own weight, drags the cable 6 down together. When the first sliding frame 4 returns to the initial position, the fixed pulley 402 moves toward the rear end of the cross frame 1, and the fixed pulley 402 pulls the cable 6 toward the rear end of the cross frame 1. At this time, the socket 7 rises by the pull of the cable 6. The present invention can slide the first sliding frame 4 on the cross frame 1 to lift up and down. Compared with the traditional fixed socket 7, the suspended lifting socket 7 is easier to use and store, improves the overall space utilization of the room and avoids the clutter caused by using power strips.

[0060] It should be noted that in this embodiment, the mass of the first sliding frame 4 is greater than the mass of the socket 7. Therefore, when the first sliding frame is in the initial position, the socket 7 cannot drag the cable 6 down by its own weight without external interference.

[0061] As a further embodiment, the hoisting and lifting socket 7 also includes a signal receiving module 9, a drive motor 10, a first synchronous pulley 11, a second synchronous pulley 12, a first synchronous belt 13, a driving pulley 14, a driven pulley 15, a second synchronous belt 16, and a second fixed bracket 17, and the top and bottom of the crossbeam 1 are respectively provided with grooves 18.

[0062] The signal receiving module 9 is mounted on and electrically connected to the power supply module 8. The signal receiving module 9 receives signals from a remote control terminal (not shown) and controls the power supply module 8 upon receiving the signal. The drive motor 10 is mounted on the front end of the crossbeam 1, and the power supply module 8 is electrically connected to the drive motor 10. The second fixed bracket 17 is located at the rear end of the crossbeam 1. The first synchronous wheel 11 is mounted at the bottom of the first fixed bracket 5 via a transmission shaft 19. Specifically, one end of the transmission shaft 19 is mounted on one side of the first fixed bracket 5, and the other end passes through one side of the first fixed bracket 5. The first synchronous wheel 11 is located between the bottom of opposite sides of the first fixed bracket 5. The second synchronous wheel 12 is mounted on the second fixed bracket 17 via a second rotating shaft 20. Specifically, both ends of the second rotating shaft 20 are fixedly mounted on opposite sides of the second fixed bracket 17. On both sides, the second synchronous pulley 12 is disposed between the opposite sides of the second fixed bracket 17. The first synchronous belt 13 is disposed in the belt groove 18 and its two ends are respectively sleeved on the first synchronous pulley 11 and the second synchronous pulley 12. The first synchronous pulley 11 and the second synchronous pulley 12 can rotate simultaneously through the first synchronous belt 13. The first synchronous belt 13 is fixedly connected to the bottom of the first sliding frame 4, that is, the first synchronous belt 13 can drive the first sliding frame 4 to slide on the cross frame 1. The driving pulley 14 is connected to the drive motor 10 through the third rotating shaft 34. The driven pulley 15 is fixedly disposed on the other end of the transmission shaft 19. Here, the other end of the transmission shaft 19 refers to the end of the transmission shaft 19 that passes through one side of the first fixed bracket 5. The two ends of the second synchronous belt 16 are respectively sleeved on the driving pulley 14 and the driven pulley 15. The driven pulley 15 drives the first synchronous pulley 11 to rotate through the transmission shaft 19.

[0063] The working principle of the hoisting and lifting socket 7 in this embodiment is as follows: When the remote control terminal (not shown) issues a descent command to the hoisting and lifting socket 7, the signal receiving module 9 receives the descent signal, and then controls the power supply module 8 to power the drive motor 10 and control the drive motor 10 to rotate forward. The forward rotation of the drive motor 10 drives the drive wheel 14 to rotate forward through the third rotating shaft 34. The drive wheel 14 drives the driven wheel 15 to rotate forward through the second synchronous belt 16. The driven wheel 15 drives the first synchronous wheel 11 to rotate forward through the transmission shaft 19. The first synchronous wheel 11 drives the second synchronous wheel 12 to rotate forward through the first synchronous belt 13. When the first synchronous belt 13 rotates forward, it drives the first sliding frame 4 to slide towards the front end of the cross frame 1. Then, the socket 7 drags the cable 6 down together under its own gravity. When the remote control terminal issues a stop command... When the stop command is issued, the power supply module 8 cuts off the power to the drive motor 10. After the drive motor 10 stops working, the first sliding frame 4 stops sliding, and the socket 7 also stops moving. When the remote control sends an upward command, the power supply module 8 powers on the drive motor 10 and controls the drive motor 10 to reverse. The drive motor 10 drives the drive wheel 14 to reverse through the third rotating shaft 34. The drive wheel 14 drives the driven wheel 15 to reverse through the second synchronous belt 16. The driven wheel 15 drives the first synchronous wheel 11 to reverse through the transmission shaft 19. The first synchronous wheel 11 drives the second synchronous wheel 12 to reverse through the first synchronous belt 13. The first synchronous belt 13 drives the first sliding frame 4 to slide towards the rear end of the cross frame 1. At this time, the fixed pulley 402 drags the cable 6 to move towards the rear end of the cross frame 1, and the socket 7 completes the upward movement under the traction of the cable 6.

[0064] It should be further explained that in this embodiment, the drive motor 10 is an existing worm gear reducer motor, which cannot be reversed under the action of external force. Therefore, in this embodiment, the socket 7 cannot drag the cable 6 and the first sliding frame 4 under its own gravity.

[0065] like Figure 8As shown, as a further embodiment, the hoisting and lifting socket 7 also includes a second sliding frame 21. The second sliding frame 21 is mounted on the crossbeam 1 and is located between the first sliding frame 4 and the first fixed bracket 5. The second sliding frame 21 includes two first side plates 2101, a first base plate 2102, several first rollers 2103, several fourth rotating shafts 2104, and a first support rod 2105 for supporting the cable 6. The number of first rollers 2103 is the same as the number of fourth rotating shafts 2104. For example, there are four first rollers 2103 and four fourth rotating shafts 2104. The left and right ends of the first base plate 2102 are fixedly connected to the bottom of the two first side plates 2101, respectively. The first base plate 2102 is located below the bottom of the crossbeam 1. The two first side plates 2101 are located on both sides of the crossbeam 1. Along the length of the crossbeam 1, the four fourth rotating shafts 2105... The fourth rotating shafts 2104 are arranged in two rows on the left and right ends of the first base plate 2102, and the bottom end of each fourth rotating shaft 2104 is fixedly set on the top side of the first base plate 2102. Each fourth rotating shaft 2104 is provided with a first roller 2103. The side of each first roller 2103 near the cross frame 1 is respectively set in the guide rails 2 on both sides of the cross frame 1. That is, the right side of the first roller 2103 at the left end of the first base plate 2102 is locked in the guide rail 2 on the left side of the cross frame 1, and the left side of the first roller 2103 at the right end of the first base plate 2102 is locked in the guide rail 2 on the right side of the cross frame 1. The second sliding frame 21 is movably set on the cross frame 1 through the cooperation of the first roller 2103 and the guide rail 2. The two ends of the first support rod 2105 are respectively connected to the two first side plates 2101, and the first support rod 2105 is located above the top of the cross frame 1. The cable 6 is suspended on the first support rod 2105. The second sliding frame 21 is disposed between the first sliding frame 4 and the first fixed bracket 5, and can support and guide the cable 6 between the first sliding frame 4 and the first fixed bracket 5.

[0066] like Figure 9As shown, in this embodiment, the first sliding frame 4 includes two second side plates 403, a second base plate 404, several second rollers 405, and several fifth rotating shafts 406. The number of second rollers 405 is the same as the number of fifth rotating shafts 406. For example, there are four second rollers 405 and four fifth rotating shafts 406. The left and right ends of the second base plate 404 are fixedly connected to the bottom of the two second side plates 403, respectively. The second base plate 404 is located below the bottom of the cross frame 1. The bottom plate of the second base plate 404 is fixedly connected to the first synchronous belt 13. The two second side plates 403 are located on the left and right sides of the cross frame 1, respectively. Along the length of the cross frame 1, the four fifth rotating shafts 406... The first rotating shaft 401 is arranged in two rows at the left and right ends of the second base plate 404, and the bottom end of each fifth rotating shaft 406 is fixedly set on the top side of the second base plate 404. Each fifth rotating shaft 406 is provided with a second roller 405. The side of each second roller 405 near the cross frame 1 is respectively set in the guide rail 2 on both sides of the cross frame 1. That is, the right side of the second roller 405 at the left end of the second base plate 404 is locked in the guide rail 2 on the left side of the cross frame 1, and the left side of the second roller 405 at the right end of the second base plate 404 is locked in the guide rail 2 on the right side of the cross frame 1. The two ends of the first rotating shaft 401 are respectively connected to the two second side plates 403, and the fixed pulley 402 is located above the top of the cross frame 1. When the first synchronous belt 13 moves, the first synchronous belt 13 drives the second base plate 404 to move. At this time, the second roller 405 on the first sliding frame 4 rolls in the guide rail 2. By setting the second roller 405 in the guide rail 2, the smoothness of the first sliding frame 4 during the sliding process can be enhanced and the resistance between it and the guide rail 2 can be reduced.

[0067] like Figure 10As shown, as a further embodiment, the hoisting and lifting socket 7 also includes a first spring wire box 22, a second spring wire box 23, and a third fixed bracket 24; wherein the specific structures of the first spring wire box 22 and the second spring wire box 23 are existing technologies, that is, the first spring wire box 22 and the second spring wire box 23 in this embodiment are taken from spring wire boxes on the existing market. The third fixed bracket 24 is disposed at the front end of the crossbeam 1, the first spring wire box 22 is disposed on the right side of the third fixed bracket 24, and the first spring wire 2201 in the first spring wire box 22 is connected to the second sliding frame 21, the second spring wire box 23 is disposed on the left side of the first sliding frame 4, and the second spring wire 2301 in the second spring wire box 23 is connected to the second sliding frame 21; along the length direction of the crossbeam 1, when the second sliding frame 21 is in the middle part of the crossbeam 1, the tension applied by the first spring wire 2201 to the second sliding frame 21 and the tension applied by the second spring wire 2301 to the second sliding frame 21 are... The initial position of the second sliding frame 21 is set in the middle of the cross frame 1. When the first sliding frame 4 moves toward the front end of the cross frame 1, the first sliding frame 4 collides with the second sliding frame 21 and the first sliding frame 4 applies a thrust to the second sliding frame 21 toward the front end of the cross frame 1. The second sliding frame 21 is pushed toward the front end of the cross frame 1 by the first sliding frame 4. When the first sliding frame 4 moves toward the rear end of the cross frame 1, the second spring wire 2301 on the first sliding frame 4 pulls the second sliding frame 21 toward the initial position. When the second sliding frame 21 is pulled to the initial position, the tension of the first spring wire 2201 and the second spring wire 2301 are equal, and the second sliding frame 21 stops moving. In this embodiment, the second spring wire 2301 serves to traction the second sliding frame 21. When the second sliding frame 21 is pushed to the front end of the cross frame 1, the first sliding frame 4 can pull the second sliding frame 21 back to its initial position via the second spring wire 2301. The first spring wire 2201 serves to limit the movement of the second sliding frame 21, ensuring that the extreme position of the second sliding frame 21 when moving towards the rear end of the cross frame 1 is at the middle of the cross frame 1. Since both the first spring wire 2201 and the second spring wire 2301 serve a traction effect, nylon ropes, steel wires, etc., can be used to replace the first spring wire box 22 and the second spring wire box 23. The first spring wire box 22 and the second spring wire box 23 used in this embodiment can avoid the cluttered arrangement of various lines on the cross frame 1. The third fixed bracket 24 is also provided with a second support rod 2401, which is located above the top of the cross frame 1, and the cable 6 is suspended on the second support rod 2401. The third fixed bracket 24 provides support and guidance for the cable 6 between the fixed pulley 402 and the first fixed bracket 5.

[0068] As a further improvement, the bottom of the first fixed bracket 5 away from the crossbeam 1 is provided with a limiting stop 501. When the first sliding frame 4 slides toward the first fixed bracket 5, the socket 7 drags the cable 6 down together under the action of gravity. When the first sliding frame 4 slides toward the end of the crossbeam 1 away from the first fixed bracket 5, the fixed pulley 402 on the first sliding frame 4 drags the cable 6 toward the rear end of the crossbeam 1. The cable 6 drags the socket 7 up, and when the end of the socket 7 connected to the cable 6 abuts against the limiting stop 501, the first sliding frame 4 stops sliding. The first fixed bracket 5 is also provided with a third support rod 502, which is used to support the cable 6. The third support rod 502 is located above the top of the crossbeam 1, and the socket 7 is suspended on the third support rod 502 through the cable 6.

[0069] like Figure 11 As shown, in this embodiment, the hoisting and lifting socket 7 also includes a U-shaped groove. The U-shaped groove is formed by bending steel plates on both sides. The U-shaped groove is located at the top of the crossbeam 1 and between the first sliding frame 4 and the third fixed bracket 24. There is a gap between the bottom of the U-shaped groove and the first synchronous belt 13 to prevent friction. The length direction of the U-shaped groove is consistent with the direction of the crossbeam 1. Part of the cable 6 is located in the U-shaped groove, that is, the portion of the cable 6 from its lower end to the fixed pulley 402 is located in the U-shaped groove. The other part of the cable 6 is suspended in the air by the fixed pulley 402, the first support rod 2105, the second support rod 2401, and the third support rod 502. Here, the other part of the cable 6 refers to the portion of the cable 6 between the fixed pulley 402 and the first fixed bracket 5. By setting a U-shaped groove at the top of the crossbeam 1, the portion of the cable 6 from its lower end to the fixed pulley 402 can be stored in the U-shaped groove, so that the cable 6 is not placed messily on the crossbeam 1.

[0070] As a further embodiment, the hoisting and lifting socket 7 also includes a first micro switch 26, a second micro switch 27, an air switch 28, a fourth fixed bracket 29, a fifth fixed bracket 30, and a support panel 31; the fourth fixed bracket 29 is disposed on the rear end of the crossbeam 1 and is located between the first sliding frame 4 and the second fixed bracket 17, and the power supply module 8 is disposed on the fourth fixed bracket 29; the fifth fixed bracket 30 is disposed on the crossbeam 1 and is located between the first sliding frame 4 and the fourth fixed bracket 29, and the second micro switch 27 is disposed on the side of the fifth fixed bracket 30 closer to the first sliding frame 4. The first micro switch 26 is disposed on the side of the third fixed bracket 24 near the second sliding frame 21. The first micro switch 26 and the second micro switch 27 are electrically connected to the power supply module 8 respectively. The support panel 31 is fixedly disposed on the cross frame 1. The air switch 28 is disposed on the support panel 31. The air switch 28 is powered by the outside, and the lower end of the cable 6 and the power supply module 8 are electrically connected to the air switch 28 respectively. That is, the air switch 28 is used to receive external power, and then the air switch 28 directs the external power to the power supply module 8 and the lower end of the cable 6 respectively. The power supply module 8 is then electrically connected to the drive motor 10, the first micro switch 26 and the second micro switch 27.

[0071] When the first sliding frame 4 pushes the second sliding frame 21 to slide toward the third fixed bracket 24, the side of the second sliding frame 21 near the front end of the cross frame 1 collides with the first micro switch 26. The first micro switch 26 sends a signal to the power supply module 8, indicating that the first sliding frame 4 has slid to the limit position at the front end of the cross frame 1. At this time, the power supply module 8 cuts off the power to the drive motor 10, and the first sliding frame 4 stops moving.

[0072] When the first sliding frame 4 slides toward the fifth fixed bracket 30, after the first sliding frame 4 collides with the second micro switch 27, the second micro switch 27 sends a signal to the power supply module 8, indicating that the first sliding frame 4 has slid to the rear limit position of the cross frame 1 (initial position). At this time, the power supply module 8 cuts off the power to the drive motor 10, and the first sliding frame 4 stops moving.

[0073] In this embodiment, by setting a first micro switch 26 and a second micro switch 27 at both ends of the crossbeam 1, the first sliding frame 4 can be automatically determined to determine whether the first sliding frame 4 needs to stop moving. The air switch 28 can protect the cable 6. When the current is too large, the air switch 28 cuts off the power, so as not to burn out the electrical equipment connected to the socket 7. The air switch 28 has a protective effect.

[0074] like Figures 12-13 As shown, as a further embodiment, the hoisting and lifting socket 7 also includes a tensioner 32. The tensioner 32 includes a U-shaped bracket and an adjusting screw 3202. One end of the U-shaped bracket with an opening is clamped on the rear end of the crossbeam 1, and the second fixed bracket 17 is disposed inside the U-shaped bracket. A gap is left between the rear end of the second fixed bracket 17 and the rear end of the U-shaped bracket. Elliptical through holes are respectively opened on both sides of the U-shaped bracket to form sliding grooves 3203. The two ends of the second rotating shaft 20 are respectively disposed in the sliding grooves 3203 on both sides of the U-shaped bracket. The end of the U-shaped bracket away from the first fixed bracket 5 is also provided with a screw hole 3204. The front end of the adjusting screw 3202 passes through the screw hole 3204 and is fixedly connected to the end of the second fixed bracket 17 away from the first fixed bracket 5. When the rear end of the adjusting screw 3202 is manually rotated, the position of the second fixed bracket 17 on the slide groove 3203 can be controlled. When the adjusting screw 3202 rotates forward, the second fixed bracket 17 moves towards the front end of the slide groove 3203; when the adjusting screw 3202 rotates in reverse, the second fixed bracket 17 moves towards the rear end of the slide groove 3203. By adjusting the position of the second fixed bracket 17, the tension of the first synchronous belt 13 can be adjusted.

[0075] like Figures 14-15 As shown, in this embodiment, the hoisting and lifting socket 7 further includes a housing 36, which is a cuboid housing 36. All structural components included in the hoisting and lifting socket 7 are disposed within the housing 36. The bottom side of the housing 36 is provided with a third through hole 3601 for the socket 7 to enter and exit the housing 36. The rear end of the housing 36 is provided with a fourth through hole 3602. The rear end of the adjusting screw 3202 passes through the fourth through hole 3602 and is disposed outside the housing 36. The top side of the housing 36 is provided with a fifth through hole 3603. The lever on the air switch 28 is disposed within the fifth through hole 3603. When the air switch 28 is closed due to excessive external power current, the lever can be moved to reopen it. The connecting plates 3 at both ends of the cross frame 1 are respectively set at the top of the first fixed bracket 5 and the top of the fourth fixed bracket 29. The connecting plate 3 at the top of the first fixed bracket 5 is bolted to the front end of the top side of the outer shell 36, and the connecting plate 3 at the top of the fourth fixed bracket 29 is bolted to the rear end of the top side of the outer shell 36. The outer shell 36 protects all structural components inside the outer shell 36 and also prevents dust from accumulating on the structural components.

The end of the auxiliary lifting rod 3302 with the second through hole 3306 is sleeved on the end of the main lifting rod 3301 with the first through hole 3304. The fixing screw 3303 passes through the first through hole 3304 and the second through hole 3306, and the two ends of the fixing screw 3303 are respectively located on both sides of the auxiliary lifting rod 3302. A nut 3308 is provided on one end of the fixing screw 3303. The main lifting rod 3301 and the auxiliary lifting rod 3302 are bolted together by the fixing screw 3303 and the nut 3308. The telescopic lifting rod 33 can adjust its length by adjusting the position of the fixing screw 3303 on the main lifting rod 3301 and the auxiliary lifting rod 3302, so that the lifting socket 7 in this embodiment is suitable for various environments.
