[0023] In the description of the present application, it is understood that the orientation or position relationship indicated by the terms "upper", "lower" and the like is based on the orientation or position relationship shown in the drawings, and is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0024] In the description of the present application, the terms "first", "second" and the like are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features.

[0025] Referring to the drawings, Figs. 1-3 In an embodiment of the present embodiment, the rope clamping piece of the rope pulling mechanism comprises an upper clamping plate 1 and a lower clamping plate 2, the upper clamping plate 1 and the lower clamping plate 2 both have a driving end 3 and a clamping end 4, the clamping end 4 cooperates with the clamping material, and the driving end 3 is in transmission connection with a clamping power source 5.

[0026] The upper clamping plate 1 and the lower clamping plate 2 are hinged to the clamping plate mounting shaft 7, and the clamping plate mounting shaft 7 is fixedly arranged relative to the push-pull piece 6. The upper push-pull arm 8 and the lower push-pull arm 9 are respectively hinged to the upper and lower sides of the push-pull piece 6. The upper push-pull arm 8 is hinged to the upper clamping plate 1, and the lower push-pull arm 9 is hinged to the lower clamping plate 2. The clamping power source 5 drives the push-pull piece 6 to move left and right. The output shaft of the clamping power source 5 is connected to the middle part of the push-pull piece 6. The upper and lower sides of the push-pull piece 6 are hinged to the upper push-pull arm 8 and the lower push-pull arm 9 to form the first hinge point 10 and the second hinge point 11. The middle part of the upper push-pull arm 8 is hinged to the upper clamping plate 1 to form the third hinge point 12. The middle part of the lower push-pull arm 9 is hinged to the lower clamping plate 2 to form the fourth hinge point 13. When clamping the material, the distance between the first hinge point 10 and the second hinge point 11 is greater than the distance between the third hinge point 12 and the fourth hinge point 13. The clamping power source 5 and the clamping plate mounting shaft 7 are arranged on the moving seat 14. The moving seat 14 moves left and right. The clamping plate mounting shaft 7 is located in the middle part of the moving seat 14. The first hinge point 10 and the second hinge point 11 are symmetrical about the axis of the output shaft of the clamping power source 5. The third hinge point 12 and the fourth hinge point 13 are symmetrical about the axis of the output shaft of the clamping power source 5.

[0027] In this embodiment, the clamping power source 5 is a pneumatic cylinder. When clamping the rope, the output shaft of the clamping power source 5 drives the push-pull piece 6 to move right. The one end of the upper push-pull arm 8 and the lower push-pull arm 9 moves right to drive the left clamping plate and the right clamping plate to swing inward. The swing of the left clamping plate and the right clamping plate makes the other end of the upper push-pull arm 8 and the lower push-pull arm 9 close during the right movement, and the clamping of the rope is completed. Because the distance between the first hinge point 10 and the second hinge point 11 is greater than the distance between the third hinge point 12 and the fourth hinge point 13, the force of the push-pull arm on the clamping plate is inclined inward, which provides sufficient clamping force on the rope. The balance force is vertically downward, and the clamping plate will not be offset. The balance force is horizontally right, and the clamping plate will not be offset. The clamping power source 5 can be a hydraulic cylinder, an oil cylinder, etc.

[0028] In other alternative embodiments, the clamping power source 5 can be connected to the connecting plate for the clamping plate mounting shaft 7.

[0029] Referring to the drawings Figs. 2-3 The clamping end 4 is provided with a positioning notch 15. The positioning notch 15 is V-shaped. The included angle of the positioning notch 15 is obtuse. The positioning notch 15 of the clamping end 4 is divided into a front section and a rear section. The two sides of the rear section are provided with inclined clamping surfaces 16. The included angle of the clamping surface 16 is smaller than the included angle of the positioning notch 15. The two sides of the front section are provided with horizontal pressing surfaces 17.

[0030] In this embodiment, the clamping surface 16 bends the two sides of the flattened rope head, and straightens the middle of the rope head. The front part of the positioning gap 15 cooperates with the pressing surface 17 to position the rope head during clamping, and the rear part of the positioning gap 15 cooperates with the clamping surface 16 to tension the rope head, so that the rope head is straight and correct, which is beneficial to the clamping of the rope inserting piece.

[0031] The above is the preferred embodiment of the present application, and it should be pointed out that the protection scope of the present application is not limited to this. For those skilled in the art, under the premise of not deviating from the technical range disclosed by the present application, many improvements and refinements or equivalent replacements can be made, which are also regarded as the protection scope of the present application.
