The rod wall of the first square rod 2 is movably sleeved with a square sleeve 3. The surface of the first square rod 2 and the inner wall of the square sleeve 3 are coated with a wear-resistant coating to improve the wear resistance of the surface of the first square rod 2 and the inner wall of the square sleeve 3. A splint 4 is fixedly provided on the upper side of the two square sleeves 3. A motor 10 is fixedly provided on the outer side of the column 1 on one side. The output end of the motor 10 is fixedly connected to one end of the first square rod 2. Push plates 5 are provided on the inner sides of the two columns 1. Through holes are provided on the upper sides of the two push plates 5 and at positions corresponding to the first square rod 2. The longitudinal cross-section of the through holes is circular to prevent interference between the first square rod 2 and the push plates 5 as much as possible. A side plate 11 is fixedly provided on the inner side of the column 1, and a rotating rod 12 is rotatably provided on the inner side of the side plate 11. The motor 10 is a reduction motor, which can provide a large and stable transmission force. The motor 10 is fixedly connected to the column 1 through a support frame, so that the connection between the motor 10 and the column 1 is more stable.

[0029] Example 2

[0030] Reference Figure 1-5The rod wall of the rotating rod 12 is provided with a transmission mechanism for driving the push rod 8 to move. The transmission mechanism includes a push rod 8 and a movable ring 7. The push rod 8 is fixedly sleeved on the rod wall of the rotating rod 12. The movable ring 7 is fixedly arranged on the side of the push plate 5 close to the push rod 8. One end of the push rod 8 extends to the rear side of the movable ring 7. A round pin 9 is fixedly provided on the front side of the end of the push rod 8 away from the rotating rod 12. The front end of the round pin 9 passes through the movable ring 7. The front end of the round pin 9 is fixedly sleeved with a retaining ring 16. The retaining ring 16 conflicts with the front side of the movable ring 7 to prevent the round pin 9 from slipping out of the movable ring 7 as much as possible.

[0031] Example 3

[0032] Reference Figure 1-5 A limiting mechanism for limiting the rotation of the rotating rod 12 is provided on the outer side of the push plate 5. The limiting mechanism includes a first gear 13 and a second gear 15. The first gear 13 is fixedly sleeved on the front end of the rotating rod 12, and the second gear 15 is meshed and arranged on the lower side of the first gear 13.

[0035] When the second gear 15 is released, the second gear 15 is reset under the action of the spring 17 and meshes with the first gear 13 again, thus completing the limit of the rotating rod 12. At this time, the motor 10 drives the first square rod 2 to rotate, so that the two splints 4 rotate to the two sides of the beam placed on the ground, and then the second gears 15 at both ends separate the second gear 15 from the corresponding first gear 13, that is, releasing the limit of the rotating rod 12, and then rotating the rotating rod 12, so that the push rod 8 rotates toward the horizontal, that is, the round pin 9 pushes the movable ring 7, and then the push plate 5 moves, and the push plate 5 pushes the corresponding square sleeve 3 to slide along the first square rod 2, so that the splints 4 on both sides clamp the beam, and then release the second gear 15. The second gear 15 is reset under the elastic force of the spring 17 and meshes with the first gear 13 again, thus completing the limit of the rotating rod 12. At this time, the motor 10 drives the first square rod 2 to rotate, so that the beam can be flipped, that is, time-saving and labor-saving clamping and lifting of the beam can be achieved.
