Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0021] Please refer to Figures 1-4 As shown, the present invention provides a technical solution:

[0022] A detachable pruning shear includes a first rotating arm 1 and a second rotating arm 3. The first rotating arm 1 and the second rotating arm 3 are rotatably connected by a hinge shaft 2. Pruning blades 4 are fixedly locked to the front ends of the first rotating arm 1 and the second rotating arm 3 by screws 5. Blade mounting grooves 7 are formed on the inner walls of the first rotating arm 1 and the second rotating arm 3 on the front side of the hinge shaft 2. T-shaped sliding grooves 8 are formed on the inner walls of the blade mounting grooves 7. The pruning blades 4 are arranged in the blade mounting grooves 7. T-shaped sliders 41 are provided on the side walls of the pruning blades 4. The T-shaped sliders 41 are in mating connection with the T-shaped sliding grooves 8. Step holes 9 are arranged side by side on the outer walls of the first rotating arm 1 and the second rotating arm 3 on the front side of the hinge shaft 2. One end of the screw 5 passes through the step hole 9 and is screwed into a threaded hole formed in the pruning blade 4. By screwing out the screw 5 from the pruning blade 4, the pruning blade 4 can be detached from the first rotating arm 1 and the second rotating arm 3, facilitating the replacement of the damaged pruning blade 4 by the user alone without replacing the entire pruning shear. Anti-slip teeth 42 are fixedly arranged at the blade edges of the pruning blades 4, and a number of anti-slip teeth 42 at the blade edges of the pruning blades 4 are arranged side by side at equal intervals. The arrangement of the anti-slip teeth 42 can prevent the branches from slipping along the blade edges of the pruning blades 4 during pruning. Handle gloves 6 are sleeved on the first rotating arm 1 and the second rotating arm 3 on the rear side of the hinge shaft 2. During the use of the pruning shear, when the pruning blade 4 is damaged or severely worn and needs to be replaced, the screws 5 can be screwed out of the pruning blade 4 one by one using an internal hexagonal wrench, and then the T-shaped sliders 41 on the pruning blade 4 are slid along the T-shaped sliding grooves 8, and the pruning blade 4 can be detached from the first rotating arm 1 and the second rotating arm 3 to replace the pruning blade 4.

[0023] On the side walls of the first rotating arm 1 and the second rotating arm 3 behind the hinge shaft 2, guiding chutes 10 are respectively formed. On the inner wall of the handle sleeve 6, a pruning handle groove 61 is formed. The tails of the first rotating arm 1 and the second rotating arm 3 are respectively connected with the pruning handle groove 61 in a matching manner. On the inner wall of the pruning handle groove 61, a guiding slider 62 is arranged, and the guiding slider 62 is connected with the guiding chute 10 in a matching manner. In the handle sleeve 6, a screw rod 63 is rotatably connected through a bearing. The front end of the screw rod 63 is screwed into the threaded grooves formed on the first rotating arm 1 and the second rotating arm 3. By rotating the screw rod 63, the handle sleeve 6 can be driven to move along the axial direction of the screw rod 63, so as to adjust the position of the handle sleeve 6. By increasing the distance between the tail end of the handle sleeve 6 and the hinge shaft 2, the pruning operation of the pruning shear can be made more labor-saving, and at the same time, the length of the pruning shear can also be extended, and the use effect is better. The rear end of the screw rod 63 extends to the outside of the handle sleeve 6 and is fixed with an adjusting handle 64. During the use process, by manually rotating the adjusting handle 64 clockwise to drive the screw rod 63 to rotate, the handle sleeve 6 can be driven to move backward along the axial direction of the screw rod 63, so as to increase the distance between the tail end of the handle sleeve 6 and the hinge shaft 2, making the pruning operation more labor-saving, and at the same time, the length of the pruning shear can also be extended.

[0024] Working principle: During use, when the pruning blade 4 is damaged or severely worn and needs to be replaced during the process of using this pruning shear, the screw 5 can be screwed out of the pruning blade 4 one by one by using an inner hexagonal wrench. Then, the T-shaped slider 41 on the pruning blade 4 is slid along the T-shaped chute 8, and the pruning blade 4 can be detached from the first rotating arm 1 and the second rotating arm 3 to replace the pruning blade 4. During the use process, by manually rotating the adjusting handle 64 clockwise to drive the screw rod 63 to rotate, the handle sleeve 6 can be driven to move backward along the axial direction of the screw rod 63, so as to increase the distance between the tail end of the handle sleeve 6 and the hinge shaft 2, making the pruning operation more labor-saving, and at the same time, the length of the pruning shear can also be extended.
