When the surfaces of the two splints 11 are respectively in close contact with the two side surfaces of the stretcher frame, and the two moving blocks 12 continue to move along the bidirectional screw rod 22, each slide rod 18 will slide relative to the corresponding moving block 12, and the first spring 19 will be deformed.

[0022] A rectangular block 25 is fixedly connected to the lower surface of each splint 11, and a bending block 28 is slidably installed on each moving block 12. A hinged rod 17 is hinged on the bending block 28, and one end of the hinged rod 17 away from the bending block 28 is hinged to the rectangular block 25. The distance between each moving block 12 and the corresponding splint 11 will be reduced, and the inclination angle of the hinged rod 17 will change. The bending blocks 28 will move up along the slide groove 29 at the same time. During the upward movement of the bending blocks 28, the upper surfaces of each bending blocks 28 will move up against the lower surface of the gravity plate 27.

[0023] A slide groove 29 with a convex cross-section is provided on one side surface of each moving block 12, and each bending block 28 is slidably connected to the corresponding slide groove 29. Two rotating disks 26 are fixedly connected to the rotating shaft 5, and a pull rope 14 is arranged between the two rotating disks 26.

After the gravity plate 27 moves up, the telescopic rod 20 is deformed. Under the elastic force of the torsion spring 24, the rotating shaft 5 will rotate in the opening and reel in the pull rope 14, and the rotating plate 15 will rotate together with the rotating shaft 5.

[0024] A support rod 7 is slidably connected to the bearing plate 16, and a push plate 13 is fixedly connected to the upper end of the support rod 7.

A limiting groove 3 with a right-angle trapezoidal cross section is provided on the fixed block 9. The support rod 7 The lower end is fixedly connected with an extrusion rod 6 with a concave cross-section. During the movement of each moving block 12, under the transmission action of the bending rod 10, the fixed block 9 will move at the same time, and the distance between the two fixed blocks 9 will increase, and the two ends of the extrusion rod 6 will gradually abut against the inclined surface of the limit groove 3. With the continuous movement of the fixed block 9, the extrusion rod 6 will move up, and the support rod 7 will slide relative to the bearing plate 16 at the same time, the second spring 8 will be deformed, and the push plate 13 will push the stretcher frame to move upward during the upward movement.

[0025] Two symmetrically arranged rectangular plates 23 are fixedly connected to the multiple supporting legs 2, and a reinforcing rod 21 is fixedly connected to each rectangular plate 23. Each reinforcing rod 21 is slidably connected to the corresponding fixed block 9. During the movement of each fixed block 9, it will simultaneously slide relative to the corresponding reinforcing rod 21, and the reinforcing rod 21 has a certain supporting effect on the fixed block 9.

[0026] A sliding opening 30 is provided on the inner wall of one side of the installation cavity, and a rectangular opening is provided on the lower inner wall of the installation cavity for the bending rod 10 to move back and forth. The sliding opening 30 can limit the moving trajectory of the moving block 12 to prevent the moving block 12 from swinging, and the rectangular opening can limit the moving trajectory of the bending rod 10 to prevent the bending rod 10 from swinging. A servo motor 4 is fixedly installed on one side of the support frame 1, and the driving end of the servo motor 4 is fixedly connected to the bidirectional screw rod 22. When the servo motor 4 is powered on, the servo motor 4 can drive the bidirectional screw rod 22 to rotate.

[0027] In the present invention, in the initial state, the push plate 13 is located inside the groove, and the upper surface of the push plate 13 is flush with the upper surface of the supporting plate 16, and the stretch frame (not shown) is placed on the supporting plate 16, and then the servo motor 4 is powered on, and the servo motor 4 drives the bidirectional screw 22 to rotate, and the two moving blocks 12 move along the bidirectional screw 22 at the same time, and the distance between the two moving blocks 12 is reduced. Under the transmission action of the two moving blocks 12, the two splints 11 move at the same time. When the surfaces of the two splints 11 are respectively in close contact with the two side surfaces of the stretch frame, the two moving blocks 12 continue to move along the bidirectional screw 22, and each slide rod 18 will slide relative to the corresponding moving block 12, and the first spring 19 will be deformed. At this time, the position of each bending block 28 is located directly below the gravity plate 27.

[0028] As each moving block 12 continues to move, the distance between each moving block 12 and the corresponding clamping plate 11 will decrease, the inclination angle of the hinge rod 17 will change, and the bending block 28 will move up along the slide slot 29 at the same time. As the bending block 28 moves up, the upper surface of each bending block 28 will move up against the lower surface of the gravity plate 27. Since one end of the inelastic pull rope 14 is fixedly connected to the gravity plate 27 and the other end is wound around the rotating shaft 5 and cannot be separated from the rotating shaft 5, the elastic force of the torsion spring 24 is smaller than the gravity of the gravity plate 27 itself, and the gravity plate 27 moves up. After that, the telescopic rod 20 is deformed, and under the elastic force of the torsion spring 24, the rotating shaft 5 will rotate in the opening and reel in the pull rope 14. After the rotating plate 15 rotates together with the rotating shaft 5, part of the surface of the rotating plate 15 will fit with the upper surface of the stretcher frame. Under the clamping action of the two clamping plates 11, the stretcher frame can be fixed and limited in the horizontal direction. Under the joint action of the bearing plate 16 and the rotating plate 15, the stretcher frame can be fixed and limited in the vertical direction, thereby realizing automatic clamping of the stretcher frame, and the installation efficiency of the stretcher frame is higher.

[0029] When the stretcher frame needs to be disassembled, the servo motor 4 drives the bidirectional screw 22 to rotate. During the movement of the two moving blocks 12 along the bidirectional screw 22, the distance between the two moving blocks 12 increases, and the rotating plate 15 rotates back to the initial position, that is, it is separated from the surface of the stretcher frame, and the surfaces of each clamping plate 11 are separated from the two side surfaces of the stretcher frame. During the movement of each moving block 12, under the transmission action of the bending rod 10, the fixed block 9 moves at the same time, and the distance between the two fixed blocks 9 increases, and the two ends of the extrusion rod 6 gradually abut against the inclined surface of the limit groove 3. As the fixed block 9 continues to move, the extrusion rod 6 will When the stretcher frame is moved upward, the support rod 7 slides relative to the support plate 16 at the same time, and the second spring 8 is deformed. During the upward movement of the push plate 13, the stretcher frame will be pushed upward until the stretcher frame is pushed to the top of the support frame 1. After that, the hydraulic cylinder 31 works, and the driving end of the hydraulic cylinder 31 moves toward the direction close to the stretcher frame, and gradually moves against the surface of the stretcher frame, so that the stretcher frame can be pushed into the storage frame (not shown), so that the stretcher frame is separated from the push plate 13, thereby realizing the automatic disassembly of the stretcher frame. During the loading and unloading process of the scaffolding, the labor intensity of the staff is relatively small, and the operation is relatively convenient and quick, which is conducive to the use of the quilting machine.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
