Description

Technical Field

[0001] The utility model belongs to the technical field of gardening tools, in particular to a pair of pruning shears. Background Art

[0002] With the development of the economy, the forestry and fruit industry, as one of the pillar industries of agriculture, is also developing rapidly. It provides a rich variety of dried and fresh fruits, prospers urban and rural markets, meets the needs of consumers, and helps fruit farmers in mountainous areas get out of poverty and become rich. In addition, in order to green the environment, many parks and green spaces have been built in cities and towns across the country, and many ornamental plants have been planted. Both fruit tree planting and gardening require pruning. Currently, common pruning shears use a traditional scissors structure to shear branches using the principle of leverage. The shearing force is related to the length of the handle. The longer the handle, the greater the shearing force. However, it is obviously unrealistic to design scissors to be long and large in order to save effort in shearing branches. Traditional scissors are relatively heavy, laborious to operate, and have low work efficiency, making it difficult to meet the shearing force requirements. Summary of the Invention

[0003] The utility model aims to provide a pruning shear which is more labor-saving to operate by gripping and pressing, has a simpler overall structure and can make pruning easier and more convenient.

[0004] The purpose of this utility model is achieved in this way:

[0005] A pruning shear comprises a left blade and a right blade hinged to the left blade via a rotating shaft, the lower end of the left blade being provided with a rotating handle which can rotate relative to the left blade, the upper end of the rotating handle being provided with a left gear portion, and the lower end of the right blade being provided with a right gear portion, the left gear portion being meshed with the right gear portion, and while driving the left blade and the right blade to rotate, the left gear portion and the right gear portion enter a meshing state, and the left blade and the right blade rotate around the rotating shaft, and while the left gear portion and the right gear portion rotate relative to each other, the rotating handle also rotates around the tail end of the left blade, thereby opening the left blade and the right blade.

[0006] Furthermore, a left rotating hole and a right rotating hole are respectively opened at the connection between the left blade and the right blade, and a rotating shaft passes through the left rotating hole and the right rotating hole. The left blade rotates around the rotating shaft through the left rotating hole, and the right blade rotates around the rotating shaft through the right rotating hole.

[0007] Furthermore, a first connecting hole is provided at the tail end of the left blade, and a second connecting hole is provided at the upper end of the rotating handle. Connecting parts are passed through the first connecting hole and the second connecting hole, and the connecting parts connect the left blade and the rotating handle. The rotating handle can rotate relative to the left blade around the connecting parts.

[0008] Furthermore, a left handle is provided at the lower end of the rotating handle, and a left mounting groove is formed at the front end of the left handle. The lower end of the rotating handle passes through the left mounting groove. A right handle is provided at the lower end of the right blade, and a right mounting groove is formed at the front end of the right handle. The lower end of the right blade passes through the right mounting groove.

[0009] Furthermore, a left fixing hole is formed at the upper end of the left handle. The connecting piece passes through the first connecting hole, the second connecting hole and the left fixing hole, so that the left handle and the rotating handle are fixedly connected, and the left handle is rotatably connected to the left blade. A right fixing hole is formed at the upper end of the right handle. The rotating shaft passes through the left rotating hole, the right rotating hole and the right fixing hole, so that the right handle and the right blade are fixedly connected.

[0010] Furthermore, a left abutting portion and a right abutting portion are respectively formed in a protruding manner on the sides of the left handle and the right handle. When the left abutting portion and the right abutting portion abut against each other, the left blade and the right blade are both in a coincident state upward along the rotating shaft.

[0011] The prominent and beneficial technical effects of the present utility model compared with the prior art are:

[0012] The purpose of the present utility model is to provide a pruning shear that is more labor-saving in gripping and pressing operations, has a simpler overall structure, and can prune more easily and conveniently. It includes a left blade and a right blade hinged to the left blade through a rotating shaft. The blades are hinged to the left blade through the rotating shaft, enabling the left blade and the right blade to open and close smoothly, thereby being able to cut off branches smoothly. A rotating handle that can rotate relative to the left blade is provided at the lower end of the left blade. A left gear portion is provided at the upper end of the rotating handle, and a right gear portion is provided at the lower end of the right blade. The left gear portion meshes with the right gear portion. While driving the left blade and the right blade to rotate, the left gear portion and the right gear portion enter the meshing state, and the left blade and the right blade rotate around the rotating shaft. While the left gear portion and the right gear portion rotate relative to each other, the rotating handle also rotates around the tail end of the left blade, thereby opening the left blade and the right blade. The end of the left blade is provided on the rotating handle. When the user wants to prune a branch, first drive the left blade and the rotating handle to separate the lower ends of the left blade and the right blade, and make the left blade and the right blade rotate around the rotating shaft. The left gear portion and the right gear portion rotate meshingly from the back to the front. Since the rotating handle is rotationally connected to the left blade, while the rotating handle drives the left blade to rotate, the rotating handle will rotate relative to the left blade around the connecting member. The present utility model mainly controls, through the meshing of the left gear portion and the right gear portion, that when the left blade and the right blade are rotated and opened, the rotating handle will rotate relative to the left blade around the connecting member, thereby controlling the angle between the lower ends of the left blade and the right blade after rotation to be greater than the angle between the left blade and the right blade after rotation, increasing the lever structure between the left blade and the handle, increasing the shearing force generated by the left blade and the right blade, reducing the force required for pruning branches, and achieving the effect of labor saving, so as to prune branches more easily and conveniently.

[0026] The present utility model will be further described below in conjunction with specific embodiments:

[0027] A pruning shear includes a left blade 1 and a right blade 3 hinged to the left blade 1 through a rotating shaft 2. A rotating handle 4 that can rotate relative to the left blade 1 is provided at the lower end of the left blade 1. A left gear part 5 is provided at the upper end of the rotating handle 4. A right gear part 6 is provided at the lower end of the right blade 3. The left gear part 5 meshes with the right gear part 6. While driving the left blade 1 and the right blade 3 to rotate, the left gear part 5 and the right gear part 6 enter the meshing state. The left blade 1 and the right blade 3 rotate around the rotating shaft 2. While the left gear part 5 and the right gear part 6 rotate relative to each other, the rotating handle 4 also rotates around the tail end of the left blade 1, so as to open the left blade 1 and the right blade 3.

[0028] The purpose of the present utility model is to provide a pruning shear that is more labor-saving in gripping and pressing operations, has a simpler overall structure, and can prune more easily and conveniently. It includes a left blade 1 and a right blade 3 hinged to the left blade 1 through a rotating shaft 2. The blades are hinged together through the rotating shaft 2, so that the left blade 1 and the right blade 3 can be smoothly opened and closed, and thus the branches can be smoothly cut off. A rotating handle 4 that can rotate relative to the left blade 1 is provided at the lower end of the left blade 1. A left gear portion 5 is provided at the upper end of the rotating handle 4, and a right gear portion 6 is provided at the lower end of the right blade 3. The left gear portion 5 meshes with the right gear portion 6. While driving the left blade 1 and the right blade 3 to rotate, the left gear portion 5 and the right gear portion 6 enter the meshing state, and the left blade 1 and the right blade 3 rotate around the rotating shaft 2. While the left gear portion 5 and the right gear portion 6 rotate relative to each other, the rotating handle 4 also rotates around the tail end of the left blade 1, so as to open the left blade 1 and the right blade 3. The end of the left blade 1 is provided on the rotating handle 4. When the user wants to prune a branch, first drive the left blade 1 and the rotating handle 4, so that the lower ends of the left blade 1 and the right blade 3 are separated, and the left blade 1 and the right blade 3 rotate around the rotating shaft 2, and the left gear portion 5 and the right gear portion 6 rotate meshingly from back to front. Since the rotating handle 4 is rotatably connected to the left blade 1, while the rotating handle 4 drives the left blade 1 to rotate, the rotating handle 4 will rotate relative to the left blade 1 around the connecting member 11. The present utility model mainly controls the angle between the lower ends of the left blade 1 and the right blade 3 after rotation to be greater than the angle between the left blade 1 and the right blade 3 after rotation by the mutual meshing of the left gear portion 5 and the right gear portion 6. When the left blade 1 and the right blade 3 are rotated and opened, the rotating handle 4 rotates relative to the left blade 1 around the connecting member 11, thereby increasing the lever structure between the lower end of the left blade 1 and the handle, increasing the shearing force generated by the left blade 1 and the right blade 3, reducing the force required for pruning branches, achieving the effect of labor saving, and being able to prune branches more easily and conveniently.

[0029] Preferably, left rotation holes 7 and right rotation holes 8 are respectively opened at the connection of the left blade 1 and the right blade 3. The rotating shaft 2 penetrates through the left rotation hole 7 and the right rotation hole 8. The left blade 1 rotates around the rotating shaft 2 through the left rotation hole 7, and the right blade 3 rotates around the rotating shaft 2 through the right rotation hole 8. The left and right handles increase the shearing force of the left blade 1 and the right blade 3. The gear meshing structure is more labor-saving, effectively enhances the driving force, reduces the direct force, realizes labor saving, increases the working efficiency, and causes less burden on the user.

[0030] Preferably, a first connection hole 9 is formed at the tail end of the left blade 1, a second connection hole 10 is formed at the upper end of the rotating handle 4, a connecting member 11 is inserted into the first connection hole 9 and the second connection hole 10, the connecting member 11 connects the left blade 1 and the rotating handle 4, and the rotating handle 4 can rotate relative to the left blade 1 around the connecting member 11.

[0031] Preferably, a left handle 12 extends from the lower end of the rotating handle 4, a left mounting groove 13 is formed at the front end of the left handle 12, the lower end of the rotating handle 4 is inserted into the left mounting groove 13, a right handle 14 extends from the lower end of the right blade 3, a right mounting groove 15 is formed at the front end of the right handle 14, and the lower end of the right blade 3 is inserted into the right mounting groove 15. The extension of the left and right handles on the rotating handle and the right handle 14 is to make it more convenient to hold the pruning shears, and the extension of the left and right handles can increase the angle difference between the upper and lower ends after the left blade 1 and the right blade 3 rotate, making the pruning shears more labor-saving when in use.

[0032] Preferably, a left fixing hole 16 is further formed at the upper end of the left handle 12, the connecting member 11 is inserted into the first connection hole 9, the second connection hole 10 and the left fixing hole 16, so that the left handle 12 and the rotating handle 4 are fixedly connected, and the left handle 12 is rotatably connected to the left blade 1. A right fixing hole 17 is further formed at the upper end of the right handle 14, the rotating shaft 2 is inserted into the left rotating hole 7, the right rotating hole 8 and the right fixing hole 17, so that the right handle 14 and the right blade 3 are fixedly connected, which is convenient to respectively mount the left and right handles on the left blade 1 and the right blade 3.

[0033] Preferably, a left abutting portion 18 and a right abutting portion 19 are respectively convexly formed on the sides of the left handle 12 and the right handle 14. When the left abutting portion 18 and the right abutting portion 19 abut against each other, the left blade 1 and the right blade 3 are both in a coincident state upward from the rotating shaft 2. When the pruning shears are not in use, the handles are combined, and the left abutting portion 18 and the right abutting portion 19 abut against each other, preventing the left blade 1 and the right blade 3 from being misaligned when they coincide, and causing the left blade 1 and the right blade 3 to open in the opposite direction and cut the user.
