[0035] As a further implementation of the scheme, the projection of the connecting rivet 31 in the vertical direction is circular, the angle between the connecting rivet 31 and the handle head assembly 21 is 90°, the inclined hole 32 is connected with the curved groove 212, the rotating plate 33 is provided with two, the two rotating plates 33 are symmetrically distributed inside the connecting rivet 31, the inner shell 34 is attached to the inside of the connecting rivet 31, the limiting groove 37 is opened in the same shape as the sliding groove 36, the side of the moving block 35 close to the rotating plate 33 is arc-shaped, and the side of the vertical plate 38 is arc-shaped. The symmetrical design of the rotating plate 33 enables the two rotating plates 33 to be simultaneously pushed by the air entering the connecting rivet 31 through the inclined hole 32, thereby better driving the moving block 35 to move and improving the operation effect of the device. The design of the limiting groove 37 and the sliding groove 36 ensures the stability and reliability of the internal mechanical mechanism, preventing the loosening or falling of the parts.

[0036] Workflow: When using the labor-saving green pruning pliers, the operator holds two opposite handle assemblies 2 at the same time, observes the branches that need to be cut, determines the specific cutting position, and simultaneously applies pressure to the two opposite handle assemblies 2. The handle assembly 2 moves with the fixed connection of the blade head 1, and the blade head 1 is limited by the rivet assembly 3 to cut the branches. When the handle assembly 2 is under pressure, the air bag ring 222 is deformed and exerts force on the pressing block 223. Since the air inside the air bag ring 222 provides a buffer when compressed, the air bag ring 222 drives the flexible contact between the pressing block 223 and the rubber tube 224, and the air inside the rubber tube 224 enters the curved groove 212 through the through hole 226, then enters the connecting rivet 31 through the inclined hole 32. The air entering the connecting rivet 31 pushes the rotating plate 33 to rotate, which in turn pushes the moving block 35 to move. Since the side of the moving block 35 is arc-shaped, it can reduce the friction between the rotating plate 33 and the moving block 35, which is conducive to force transmission. When the moving block 35 moves, the vertical plate 38 passes through the limiting groove 37 in the inner shell 34 and leaks out of the sliding groove 36, thereby increasing the friction between the connecting rivet 31 and the handle head assembly 21. The arc-shaped side of the vertical plate 38 can effectively prevent scratches and damage when the vertical plate 38 comes into contact with the handle head assembly 21. When the connecting rivet 31 rotates between the handle head assemblies 21, the increased friction allows the handle assembly 2 to cut the branches with the blade head 1 without providing excessive cutting force, preventing the branches from breaking and causing damage to the operator. The different diameters of the two ends of the rubber tube 224 allow the air inside the rubber tube 224 to be expelled in different amounts when the air bag ring 222 at different positions is compressed, better adapting to different lengths of torque when holding the handle assembly 2 at different positions. This meets the requirement of labor saving while achieving the effect of balanced buffering of the rivet assembly 3.

[0037] While the embodiments of the present application have been illustrated and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the spirit and scope of the application, which is defined by the appended claims and their equivalents.
