[0002] As the name implies, a hedge shear is a gardening scissor used to trim hedges and shrubs. Currently, common hedge shears adopt the traditional scissor structure and use the lever principle to cut branches. The cutting force is related to the length of the handle. The longer the handle, the greater the cutting force. However, it is obviously unrealistic to design the scissors to be long and large in order to cut branches with higher toughness. And traditional scissors are difficult to meet the need for cutting force. It is very laborious to cut branches with higher toughness, and it is easy for users to get tired after working with such hedge shears for a long time. Therefore, it is necessary to provide a hedge shear that can easily cut off branches with higher toughness, which is beneficial for users to use. Summary of the Invention

[0003] The purpose of the utility model is to provide a hedge shear with a simple structure, which can easily cut off branches with higher toughness, is more labor-saving for users during use, and is beneficial for users to use.

[0005] A hedge shear includes a left blade, a right blade hinged to the left blade through a rotating shaft, and a left handle and a right handle respectively rotatably connected to the ends of the left blade and the right blade. The left handle and the right handle can rotate relative to the left blade and the right blade respectively. The front ends of the left handle and the right handle are respectively provided with a left rotating part and a right rotating part. The left rotating part and the right rotating part are respectively provided with a left gear part and a right gear part. The left gear part and the right gear part can be meshed with each other. After driving the left handle and the right handle to rotate relative to the left blade and the right blade respectively, the left gear part and the right gear part enter the meshing state. At this time, continuing to rotate the left handle and the right handle can respectively drive the left blade and the right blade to rotate around the rotating shaft to open.

[0006] Furthermore, a guiding member is provided on the right blade. The guiding member is connected to the rotating shaft. The bottom parts of the left rotating part and the right rotating part are respectively formed with a left limiting gear part and a right limiting gear part. The left and right sides of the guiding member are respectively provided with a left guiding gear part and a right guiding gear part. The left guiding gear part and the right guiding gear part can be respectively meshed with the left limiting gear part and the right limiting gear part.

[0007] Further, rotation holes are formed in both the left blade and the right blade, a guiding hole is formed in the guiding member, the top end of the rotating shaft passes through the rotation hole and the guiding hole, a connecting cap is provided at the bottom end of the rotating shaft, the bottom of the connecting cap abuts against the lower surface of the left blade, a clamping portion is formed by extending the top end of the rotating shaft, and the clamping portion abuts against the upper surface of the guiding member.

[0009] Further, placing grooves are formed on the upper surfaces of both the left handle and the right handle, the linkage holes are formed at the bottoms of the placing grooves, and the installation caps are located in the placing grooves.

[0010] Further, hanging holes are formed at the rear ends of both the left handle and the right handle.

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

[0012] A hedge shear, comprising a left blade, a right blade hinged to the left blade through a rotating shaft, and a left handle and a right handle respectively rotatably connected to the ends of the left blade and the right blade. The left handle and the right handle are respectively rotatable relative to the left blade and the right blade. The front ends of the left handle and the right handle are respectively provided with a left rotating part and a right rotating part. The left rotating part and the right rotating part are respectively provided with a left gear part and a right gear part. The left gear part and the right gear part can be meshed with each other. After driving the left handle and the right handle to rotate relative to the left blade and the right blade respectively, the left gear part and the right gear part enter a meshing state. At this time, continuing to rotate the left handle and the right handle can respectively drive the left blade and the right blade to rotate around the rotating shaft to open. The left blade is hinged to the left blade through the rotating shaft, so that the left blade and the right blade can be smoothly opened and closed, so that the branches can be smoothly cut off. And the left handle and the right handle are respectively rotatably connected to the ends of the left blade and the right blade. When the user wants to prune the branches, first hold the left handle and the right handle and rotate the left handle and the right handle relative to the left blade and the right blade respectively, so that the left handle and the right handle are away from each other. Since the left rotating part on the left handle has a left gear part and the right rotating part on the right handle has a right gear part, when the left handle and the right handle are rotating, they actually rotate around the rotation point where the left gear part and the right gear part can be meshed with each other. When the left handle and the right handle rotate relative to the left blade and the right blade to a certain angle, the left gear part and the right gear part are initially meshed together. At this time, the left handle and the right handle can no longer rotate relative to the left blade and the right blade respectively. When the user continues to control the left handle and the right handle to rotate, at this time, the left handle and the right handle will respectively drive the left blade and the right blade to rotate around the rotating shaft, so that the left blade and the right blade are opened. Then move the hedge shear closer to the branches to be pruned so that the branches are located between the left blade and the right blade. At this time, the user moves the left handle and the right handle closer. Since the left gear part and the right gear part are meshed together at this time, when the left handle and the right handle are close to each other, the left blade and the right blade will also be close to each other, so as to cut off the branches between the left blade and the right blade. Compared with the common hedge shears on the market that adopt the traditional scissor structure and use the lever principle to cut the branches, 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 the scissors to be long and large in order to cut branches with higher toughness. When the above hedge shear is used to cut branches with higher toughness, it is very laborious. When the user uses this kind of hedge shear for a long time, it is easy to get tired. In the present utility model, when the left blade and the right blade are close to each other, the mutual meshing and rotation of the left gear part and the right gear part will increase the shearing force generated by the left blade and the right blade, and the angle between the left handle and the right handle after rotation is greater than the angle between the left blade and the right blade after rotation, so that the branches with higher toughness can be smoothly cut off without spending too much effort, which is beneficial to the user to use the hedge shear.

[0031] The following further describes the present utility model in conjunction with specific embodiments:

[0032] A hedge shear, comprising a left blade 1, a right blade 3 hinged to the left blade 1 through a rotating shaft 2, and a left handle 4 and a right handle 5 rotatably connected to the ends of the left blade 1 and the right blade 3 respectively. The left handle 4 and the right handle 5 are respectively rotatable relative to the left blade 1 and the right blade 3. The front ends of the left handle 4 and the right handle 5 are respectively provided with a left rotating part 6 and a right rotating part 7. The left rotating part 6 and the right rotating part 7 are respectively provided with a left gear part 8 and a right gear part 9. The left gear part 8 and the right gear part 9 can be meshed with each other. After driving the left handle 4 and the right handle 5 to rotate relative to the left blade 1 and the right blade 3 respectively, the left gear part 8 and the right gear part 9 enter a meshed state. At this time, continuously rotating the left handle 4 and the right handle 5 can respectively drive the left blade 1 and the right blade 3 to rotate around the rotating shaft 2 to open;The left blade 1 is hinged to the left blade 1 through a rotating shaft 2, so that the left blade 1 and the right blade 3 can be smoothly opened and closed, so that the branches can be smoothly cut off. The left grip 4 and the right grip 5 are respectively rotatably connected to the ends of the left blade 1 and the right blade 3. When the user wants to prune the branches, first hold the left grip 4 and the right grip 5 and make the left grip 4 and the right grip 5 rotate relative to the left blade 1 and the right blade 3 respectively, so that the left grip 4 and the right grip 5 move away from each other. Since the left rotating part 6 on the left grip 4 has a left gear part 8 and the right rotating part 7 on the right grip 5 has a right gear part 9, when the left grip 4 and the right grip 5 are rotating, they actually rotate around the rotation point where the left gear part 8 and the right gear part 9 can mesh with each other. When the left grip 4 and the right grip 5 rotate relative to the left blade 1 and the right blade 3 to a certain angle, the left gear part 8 and the right gear part 9 are initially meshed together. At this time, the left grip 4 and the right grip 5 can no longer rotate relative to the left blade 1 and the right blade 3 respectively. When the user continues to control the left grip 4 and the right grip 5 to rotate, at this time, the left grip 4 and the right grip 5 will respectively drive the left blade 1 and the right blade 3 to rotate around the rotating shaft 2, so that the left blade 1 and the right blade 3 are opened. Then move the hedge shear closer to the branches to be pruned so that the branches are located between the left blade 1 and the right blade 3. At this time, the user moves the left grip 4 and the right grip 5 closer. Since the left gear part 8 and the right gear part 9 are meshed together at this time, when the left grip 4 and the right grip 5 move closer, the left blade 1 and the right blade 3 will also move closer, so as to cut off the branches between the left blade 1 and the right blade 3. Compared with the common hedge shears on the market that adopt the traditional scissors structure and use the lever principle to cut the branches, the cutting force is related to the length of the grip. The longer the grip, the greater the cutting force. However, it is obviously unrealistic to design the scissors to be long and large in order to cut branches with higher toughness. When the above hedge shear is used to cut branches with higher toughness, it is very laborious. When the user uses this kind of hedge shear to work for a long time, it is easy to get tired. In the present utility model, when the left blade 1 and the right blade 3 move closer, the mutual meshing and rotation of the left gear part 8 and the right gear part 9 will increase the cutting force generated by the left blade 1 and the right blade 3, and the angle between the left grip 4 and the right grip 5 after rotation is greater than the angle between the left blade 1 and the right blade 3 after rotation, so that the branches with higher toughness can be smoothly cut off without spending too much effort, which is beneficial to the user to use the hedge shear.;
