[0028] Working Principle: A second pruning shearer 3 is rotatably connected to pruning shearer 1 via a connecting button 2. Handles 4 are fixedly connected to the rear sides of both pruning shearer 1 and pruning shearer 3. A mounting groove 5 is provided on one side of each pruning shearer 1 and pruning shearer 3. A blade 6 is slidably connected to the inner side of the mounting groove 5. A blade 7 is fixedly connected to the outer surface of the blade 6. A connecting groove 8 is provided at the end of the blade 6. A spring 9 is fixedly connected to the inner side of the connecting groove 8. A connecting plate 10 is fixedly connected to the outer surface of the spring 9. A fixing groove 11 is slidably connected to the outer surface of the connecting plate 10. A bolt 12 is connected to the upper surface of the connecting plate 10. The blade 7 can be disassembled by slidably connecting the blade 6 to pruning shearer 1. When it is necessary to disassemble and replace the blade 7, the bolt 12 is rotated to... Bolt 12 rotates and separates from connecting plate 10. Then, by pulling blade 7, connecting plate 10 is subjected to force and squeezed, thus sliding into the inner side of connecting groove 8. This allows blade 6 to slide out from the inner side of mounting groove 5, thereby removing blade 7 from pruner 1. When a new blade 7 needs to be replaced, pressing the two sets of connecting plates 10 causes them to slide into the inner side of connecting groove 8. Blade 6 is then slid into the inner side of mounting groove 5. Once blade 6 is fully inside mounting groove 5, the elasticity of spring 9 causes connecting plate 10 to quickly slide into the inner side of fixing groove 11. Bolt 12 then secures blade 6 and blade 7 to pruner 1, facilitating the replacement of blade 7.
