A fixing block 12 is fixedly installed on one side of the clamping plate 11 close to the inner wall of the adjusting plate 8. A spring 10 is provided on the inner wall of the adjusting plate 8. A gear 14 is fixedly installed on the output shaft of the motor 4. A gear ring 15 is fixedly installed on the outer wall of the connecting column 5. A cylinder 16 is fixedly installed on the inner wall of the connecting column 5. A pressing plate 17 is fixedly installed on the telescopic end of the cylinder 16. In the above structure, the pressing plate 17 is located at the bottom of the supporting plate 6. By starting the cylinder 16, the telescopic end of the cylinder 16 moves downward, thereby driving the pressing plate 17 to move downward, so that the pressing plate 17 presses the top of the ring network cabinet below.

[0022] In a preferred embodiment, two extension blocks are provided on the top of the adjustment plate 8, and the extension blocks are located inside the support plate 6. The two extension blocks on the top of the adjustment plate 8 are respectively penetrated by the guide rail 7 and the double-headed screw 13. In the above structure, the extension blocks on the top of the adjustment plate 8 are penetrated by the guide rail 7, so that the guide rail 7 limits the adjustment plate 8 through the extension blocks on the top of the adjustment plate 8, so that the guide rail 7 will not tilt when moving. At the same time, through the threads provided on the outer wall of the double-headed screw 13, by rotating the double-headed screw 13, the double-headed screw 13 drives the extension blocks on the top of the adjustment plate 8 to move.

[0023] In a preferred embodiment, the spring 10 is located between the clamping plate 11 and the adjusting plate 8, and the two ends of the spring 10 are overlapped on the side of the clamping plate 11 close to the adjusting plate 8 and the inner wall of the clamping plate 11 respectively. In the above structure, when the adjusting plate 8 moves toward the ring network cabinet as a whole, the clamping plate 11 is fitted with the outer wall of the ring network cabinet, and then the clamping plate 11 moves toward the adjusting plate 8. By moving the clamping plate 11 toward the adjusting plate 8, the spring 10 contracts, so that the spring 10 forms tension, and then the clamping plate 11 obtains the force to move toward the outer wall of the ring network cabinet.

[0024] In a preferred embodiment, there are two adjusting plates 8, springs 10, clamping plates 11 and fixing blocks 12, and the two adjusting plates 8, springs 10, clamping plates 11 and fixing blocks 12 are symmetrically distributed at the bottom of the support plate 6, and the extension blocks at the top of the two adjusting plates 8 are respectively located at the two ends of the double-headed screw 13. In the above structure, by starting motor 2 9, motor 2 9 drives the double-headed screw 13 to rotate, and the double-headed screw 13 drives the two adjusting plates 8 to move toward the ring network cabinet located in the middle through the thread. When the two clamping plates 11 are in contact with the outer wall of the ring network cabinet, the two clamping plates 11 are forced to move toward the inner wall of the two adjusting plates 8 through pressure, thereby causing the spring 10 to contract, so that the spring 10 forms an outward tension, and then the two clamping plates 11 obtain force toward the outer walls of the two sides of the ring network cabinet, thereby fixing the two sides.

[0025] In a preferred embodiment, an annular groove is provided on the outer wall of the connecting column 5, and an annular extension piece is provided on the inner wall of the fixing sleeve 3 at a position close to the annular groove on the outer wall of the connecting column 5, and the annular extension piece on the inner wall of the fixing sleeve 3 is located inside the annular groove on the outer wall of the connecting column 5. In the above structure, the annular piece on the inner wall of the fixing sleeve 3 is located in the annular groove on the outer wall of the connecting column 5, so that the annular piece on the inner wall of the fixing sleeve 3 limits the connecting column 5 through the annular groove on the outer wall of the connecting column 5, so that the connecting column 5 can only rotate on the inner wall of the fixing sleeve 3.

[0026] In a preferred embodiment, the gear 14 and the gear ring 15 have the same height, and the outer walls of the gear 14 and the gear ring 15 are meshed. In the above structure, by starting the motor 4, the motor 4 drives the gear 14 to rotate, the gear 14 drives the gear ring 15 to rotate through the meshing of the outer wall with the gear ring 15, the gear ring 15 drives the connecting column 5 to rotate, and the connecting column 5 drives the support plate 6 to rotate.

[0027] Working principle: when using this equipment, the bottom of the ring network cabinet is padded so that the ring network cabinet is suspended, and two adjustment plates 8 are placed on both sides of the ring network cabinet. By starting motor 29, motor 29 drives the double-headed screw 13 to rotate, and the double-headed screw 13 drives the two adjustment plates 8 to move toward the ring network cabinet through the threads of the outer wall. By padded at the bottom of the ring network cabinet, the bottom of the adjustment plate 8 enters the bottom of the ring network cabinet. When the clamping plates 11 inside the two adjustment plates 8 contact the two sides of the outer wall of the ring network cabinet, the two clamping plates 11 are forced to move toward the inner walls of the two adjustment plates 8 through pressure, thereby contracting the spring 10, so that the spring 10 forms an outward tension, and then the two clamping plates 11 obtain force toward the outer walls of the two sides of the ring network cabinet, thereby fixing the two sides. At this time, the two clamping plates 11 hold the ring network cabinet. It is fixed in the middle. At this time, the cylinder 16 is started, so that the telescopic end of the cylinder 16 moves downward, thereby driving the pressure plate 17 to move downward, so that the pressure plate 17 presses the top of the ring network cabinet below, thereby fixing the top of the ring network cabinet. At this time, the mechanical crane arm 1 is started, and the mechanical crane arm 1 lifts the bottom, thereby lifting the ring network cabinet. When the ring network cabinet needs to be rotated and adjusted, the motor 4 is started, and the motor 4 drives the gear 14 to rotate, and the gear 14 drives the gear ring 15 to rotate. The gear 14 drives the connecting column 5 to rotate on the inner wall of the fixed sleeve 3, thereby making the connecting column 5 drive the support plate 6 to rotate, and the rotation of the support plate 6 drives the two adjustment plates 8 at the bottom to rotate, and the two adjustment plates 8 drive the ring network cabinet to rotate, thereby making the ring network cabinet rotate to adjust its position.
