In the above mentioned garden shears with improved structure, the driving mechanism includes a first gear, the first gear is coaxially and fixedly arranged on the first rotating shaft,
the cutter is characterized in that a first fixed vertical rod and a second fixed vertical rod are fixedly arranged on the inner side face of the second cutting edge, the first fixed vertical rod and the second fixed vertical rod are respectively located on two sides of the first cutting edge, a first fixed transverse rod and a second fixed transverse rod are fixedly arranged on the opposite faces of the first fixed vertical rod and the second fixed vertical rod respectively, circular-arc-shaped racks are fixedly arranged on the opposite faces of the first fixed transverse rod and the second fixed transverse rod, the circular-arc-shaped racks are coaxially arranged with the hinged shaft, the circular-arc-shaped tooth surfaces of the circular-arc-shaped racks face towards the first cutting edge, the circular-arc-shaped racks are meshed with the first gear, and the first fixed transverse rod, the second fixed transverse rod and the circular-arc-.

Compared with the prior art, the gardening scissors with the improved structure have the following advantages:
1. the free end of the second rod is in contact with the outer surface of the cutting member and carries the cutting member in the direction of the cutting gap. Since the shears have an inertia that remains during movement, the shears will move towards the first rod along the length of the second rod, so that the shears are located in the recess formed between the first and second rods. Alternatively, the recess receives the cutting member as the first rod moves, the cutting member contacts the first rod, the cutting member moves under its own inertia onto the second rod, and contact with the second rod generates a frictional force which may act to prevent the cutting member from sliding out of the recess.
2. The shears are moved into the shearing gap by the first and second rods. As the first and second blades rotate, the shearing gap gradually decreases, and the first and second blades will contact the outer surface of the object to be sheared and finally cut the object. The structure can replace the working mode of pulling the shearing object close by other tools and then shearing the shearing object, and the shearing of the shearing object positioned outside the shearing gap can be realized only by operating the first handle and the second handle in the process, so that the operation is convenient.
3. When the second rod moves, the triangular ridge is driven, so that the triangular ridge moves around the second rotating shaft. In the process, when the third surface is in contact with the outer surface of the cutting object, the cutting object moves towards the concave part along the third surface, so that the guiding function is achieved; when the concave part holds the shearing object, and the shearing object moves towards the first surface along the length direction of the second rod, the shearing object stops moving after contacting with the first surface, so that the first surface can play a role in blocking, and the shearing object is prevented from sliding out of the concave part.
4. In first pole and second pole drive the shearing thing and move to shearing the clearance, when the surface contact of first cutting edge and second cutting edge and shearing thing simultaneously, the thing will be blocked between first cutting edge and second cutting edge, and first pole and second pole are difficult to drive the thing and continue to move of shearing to make the horticulture of this improvement structure cut the card dead, can't work. In order to avoid the situation, after the object to be cut is clamped between the first blade and the second blade, the first blade and the second blade continue to rotate, and meanwhile, the second rotating shaft also rotates, but the first rod or the second rod generates acting force with the object to be cut, and the acting force contracts or extends the scroll spring, so that the scroll spring generates deformation, and the situation that the object to be cut is clamped is prevented. After the first blade and the second blade cut the object to be cut, the elastic force generated by the deformation of the spiral spring can quickly separate the upper part or the lower part of the object to be cut from the gardening scissors with the improved structure, thereby improving the working efficiency.

Detailed Description
The following are specific embodiments of the present invention and are further described with reference to the drawings, but the present invention is not limited to these embodiments.
The first embodiment is as follows:
referring to fig. 1 to 7, a pair of garden shears with an improved structure, including a first blade 12 and a second blade 13 which are crossed and hinged through a hinge shaft 15, wherein the first blade 12 is located above the second blade 13, the lower end of the first blade 12 is fixedly connected with a first handle 1, the lower end of the second blade 13 is fixedly connected with a second handle 11 which is arranged opposite to the first handle 1, and the garden shears further include:
the first rotating shaft 3 is rotatably arranged on the outer side surface of the first blade 12 and is positioned near a hinge shaft 15, and a driving mechanism capable of driving the first rotating shaft 3 to rotate when the first blade 12 and the second blade 13 rotate around the hinge shaft 15 is arranged between the first rotating shaft 3 and the hinge shaft 15;
the second rotating shaft 4 is rotatably arranged on the outer side surface of the first blade 12 and is positioned between the tip of the first blade 12 and the first rotating shaft 3, and a transmission mechanism capable of driving the second rotating shaft 4 to rotate through the first rotating shaft 3 is arranged between the second rotating shaft 4 and the first rotating shaft 3;
and one end of the first rod 6 is arranged on the second rotating shaft 4, the other end of the first rod 6 extends out of the outer side edge of the first blade 12, a second rod 61 is fixedly arranged at the end part of the first rod, and the included angle between the second rod 61 and the first rod 6 is 45-135 degrees and faces the second blade 13.
A shearing gap 14 is formed between the first blade 12 and the second blade 13, the inner edge of the outer side surface of the first blade 12 is a first cutting edge 121, and a flat surface 122 is formed between the outer edge of the outer side surface of the first blade 12 and the first cutting edge 121. The first rotating shaft 3 and the second rotating shaft 4 are both vertically located on the flat surface 122.
The first and second grips 1 and 11 are operated so that the first and second blades 12 and 13 rotate about the hinge shaft 15, and the cut object cannot be cut when the cut object is located outside the cutting gap 14. Meanwhile, when the first blade 12 and the second blade 13 rotate around the hinge shaft 15, the driving mechanism is driven, the driving mechanism drives the first rotating shaft 3 to rotate, and the first rotating shaft 3 drives the second rotating shaft 4 through the transmission mechanism. The second pivot 4 carries the first rod 6, and the first rod 6 carries the second rod 61, so that the second rod 61 moves around the second pivot 4 in the direction of the shear gap 14. In the process, the free end of the second rod 61 comes into contact with the outer surface of the cutting object and entrains the cutting object in the direction of the cutting gap 14. Since the shear has an inertia that remains during the movement, the shear will move along the length of the second rod 61 towards the first rod 6, so that the shear is located in the recess 62 formed between the first rod 6 and the second rod 61. Alternatively, the recess 62 receives the cutting when the first rod 6 moves, the cutting comes into contact with the first rod 6, the cutting moves onto the second rod 61 under its own inertia, and the contact with the second rod 61 generates a frictional force that may function to prevent the cutting from sliding out of the recess 62.
The cutting object is moved into the cutting gap 14 by the first rod 6 and the second rod 61. As the first blade 12 and the second blade 13 rotate, the cutting gap 14 is gradually reduced, and the first blade 12 and the second blade 13 will contact the outer surface of the object to be cut, and finally cut the object to be cut. The structure can replace the working mode of pulling the cut object close by other tools and then cutting the cut object, and the cut object positioned outside the cutting gap 14 can be cut only by operating the first handle 1 and the second handle 11 in the process, so that the operation is convenient.
Preferably, the second shaft 4 is located on the flat surface 122 near the tip of the first cutting edge 121, thereby increasing the length of the first shaft 6 extending beyond the first blade 12 and extending the range of motion of the first shaft 6 and the second shaft 61. The angle between the first rod 6 and the second rod 61 is 90 degrees, which not only enlarges the movement range of the second rod 61, but also ensures that the cutting objects can not slide out of the concave part 62.
Particularly, the stupefied 7 of triangle of the rectangular shape that still sets up vertically downwards, the stupefied 7 of triangle has first face 71, second face 72 and the third face 73 that the head and the tail connected gradually, the free end fixed connection of first face 71 and second pole 61, the contained angle that forms between first face 71 and the second pole 61 is the acute angle, the contained angle that forms between first face 71 and the third face 73 is the obtuse angle, the contained angle that forms between first face 71 and the second face 72 is the acute angle, and the contained angle that forms between second face 72 and the third face 73 is the acute angle.
When the second rod 61 moves, the triangular ridge 7 is carried along, so that the triangular ridge 7 moves around the second rotating shaft 4. In the process, when the third face 73 is in contact with the outer surface of the cut object, the cut object will move along the third face 73 toward the concave portion 62, thereby serving as a guide; when the cutout is received in the recess 62 and the cutout is moved toward the first surface 71 along the length of the second rod 61, the cutout stops moving after contacting the first surface 71, so that the first surface 71 can function as a stopper to prevent the cutout from slipping out of the recess 62.
Preferably, the included angle formed between the second surface 72 and the third surface 73 is 30 degrees, so that better guiding function can be achieved. The included angle formed between the second surface 72 and the first surface 71 is 60 degrees, and the included angle formed between the first surface 71 and the second rod 61 is 90 degrees, so that a better blocking effect can be achieved.
In particular, the driving mechanism comprises a first gear 31, the first gear 31 is coaxially fixed on the first rotating shaft 3,
the inner side surface of the second blade 13 is fixedly provided with a first fixed vertical rod 21 and a second fixed vertical rod 22, the first fixed vertical rod 21 and the second fixed vertical rod 22 are respectively positioned at two sides of the first blade 12, the opposite surfaces of the first fixed vertical rod 21 and the second fixed vertical rod 22 are respectively fixedly provided with a first fixed cross rod 211 and a second fixed cross rod 221, the opposite surfaces of the first fixed cross rod 211 and the second fixed cross rod 221 are fixedly provided with an arc-shaped rack 2, the arc-shaped rack 2 and the hinge shaft 15 are coaxially arranged, the arc-shaped tooth surface of the arc-shaped rack 2 faces the first blade 12, the arc-shaped rack 2 is meshed with the first gear 31, and the first fixed cross rod 211, the second fixed cross rod 221 and the arc-shaped rack 2 are all positioned above the first blade 12.
When the first blade 12 and the second blade 13 rotate around the hinge shaft 15, the first gear 31 and the circular arc-shaped rack 2 perform relative movement, i.e., the first gear 31 rotates around the circular arc-shaped rack 2. Meanwhile, the first gear 31 rotates to drive the first rotating shaft 3 to rotate, and the first rotating shaft 3 drives the second rotating shaft 4 to rotate through the transmission mechanism.
Because the first fixed vertical rod 21 and the second fixed vertical rod 22 are respectively located at two sides of the first blade 12, and the first fixed cross rod 211, the second fixed cross rod 221 and the circular-arc-shaped rack 2 are all located above the first blade 12, the first fixed vertical rod 21, the second fixed vertical rod 22, the first fixed cross rod 211, the second fixed cross rod 221 and the circular-arc-shaped rack 2 do not limit the rotation of the first blade 12 and the second blade 13.
Specifically, the transmission mechanism includes a second gear 32, the second gear 32 is coaxially fixed on the first rotating shaft 3 and is located below the circular arc-shaped rack 2, a third gear 41 is coaxially fixed on the second rotating shaft 4, the third gear 41 is located below the first rod 6, and the third gear 41 and the second gear 32 are in transmission connection through a chain 42.
The second gear 32 is carried along when the first rotary shaft 3 rotates. The second gear 32 drives the third gear 41 through the chain 42, and the third gear 41 drives the second rotating shaft 4 to rotate.
Specifically, the radius of the circular arc-shaped rack 2 is larger than that of the second gear 32, and the diameter of the second gear 32 is larger than that of the first gear 31 and the third gear 41.
Because the circular arc-shaped rack 2 is fixed on the second blade 13, the position of the first rotating shaft 3 which is rotatably arranged on the first blade 12 is always unchanged, so that the first angular speed of the relative rotation of the first blade 12 and the second blade 13 is equal to the second angular speed of the first gear 31 rotating around the circular arc-shaped rack 2;
since the radius of the first gear 31 is smaller than that of the circular arc-shaped rack 2, the third angular velocity of the rotation of the first gear 31 itself is greater than the second angular velocity;
since the first gear 31 and the second gear 32 are coaxially disposed through the first rotating shaft 3, the angular velocities of the first gear 31 and the second gear 32 are the same. But the linear velocity at the edge of the second gear 32 is greater than the linear velocity at the edge of the first gear 31. The third gear 41 is in transmission connection with the second gear 32 via the chain 42, so that the fourth angular velocity of the third gear 41 is greater than the third angular velocity of the first gear 31, and also greater than the first angular velocity.
The fourth angular speed of the third gear 41 is the speed of the second rotating shaft 4 when rotating, so that the rotating speed of the second rotating shaft 4 is greater than the relative rotating speed of the first blade 12 and the second blade 13, and the first rod 6 and the second rod 61 drive the cut object to move into the cutting gap 14, thereby facilitating the first blade 12 and the second blade 13 to cut the cut object.
Referring to fig. 1, 3, 4 and 5, specifically, a spiral spring 5 is disposed on the second rotating shaft 4, one end of the spiral spring 5 is fixedly disposed on the second rotating shaft 4, and the other end is fixedly connected to the end of the first rod 6.
In first pole 6 and second pole 61 drive the shearing thing and move to shearing clearance 14, when first cutting edge 12 and second cutting edge 13 contacted with the surface contact of shearing thing simultaneously, the shearing thing will block between first cutting edge 12 and second cutting edge 13, and first pole 6 and second pole 61 are difficult to drive the shearing thing and continue to move to make the horticulture of this improvement structure cut the card dead, can't work. To avoid such a situation, after the cutting object is clamped between the first blade 12 and the second blade 13, the first blade 12 and the second blade 13 continue to rotate, and at the same time, the second rotating shaft 4 also rotates, but an acting force is generated between the first rod 6 or the second rod 61 and the cutting object, and the acting force contracts or extends the volute spring 5, so that the volute spring 5 generates a deformation amount, and the gardening shears with the improved structure are prevented from being clamped. After the first blade 12 and the second blade 13 cut the cut object, the elastic force generated by the deformation amount of the spiral spring 5 can rapidly separate the upper part or the lower part of the cut object from the garden shears with the improved structure, thereby improving the working efficiency.
Specifically, spring connecting blocks 16 are fixedly arranged on the opposite surfaces of the first handle 1 and the second handle 11, and a return spring 17 is arranged between the two spring connecting blocks 16.
When the cutting gap 14 is gradually reduced, the distance between the first handle 1 and the second handle 11 is also gradually reduced, so as to compress the return spring 17, and the return spring 17 is compressed to generate an elastic force, which facilitates the separation of the first handle 1 and the second handle 11 after cutting off the cut object, and also drives the first gear 31 to move downwards around the circular arc-shaped rack 2.
Example two:
the present embodiment is substantially the same as the first embodiment, except that:
referring to fig. 8, the return spring 17 and the two spring connecting blocks 16 are replaced by a hydraulic rod 18, the end of a piston cylinder of the hydraulic rod 18 is hinged on the first handle 1, the end of the piston rod is hinged on the second handle 11, the first handle 1 is provided with a controller 8 and a storage battery 9, and the controller 8 is electrically connected with the hydraulic rod 18 through the storage battery 9.
During operation, the hydraulic rod 18 is started, and the hydraulic rod 18 drives the first handle 1 and the second handle 11 to move, so as to drive the first blade 12 and the second blade 13 to move, and further, the first rod 6 and the second rod 61 drive the shearing object to move into the shearing gap 14. This structure facilitates the operation of the first and second grips 1 and 11.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications or additions may be made to the described embodiments or alternatives may be employed by those skilled in the art without departing from the spirit or ambit of the invention as defined in the appended claims.
