Description

Technical Field

[0001] This utility model relates to the field of scissors technology, and in particular to hydraulic pull-out garden scissors for high branches. Background Technology

[0002] Garden pruning shears are a specialized gardening tool used to trim branches at higher elevations. Through the combination of a long handle and scissors, they allow for easy cutting of hard-to-reach branches. Existing pruning shears lack a fixed function, making them prone to opening and causing injury. This increases the difficulty of operation, reduces the pruning shears' applicability, and diminishes their practicality.

[0003] Patent CN215454127U discloses a type of high-branch shears for landscaping. The user folds the shear body closed and then manually rotates a screw. The screw rotation causes a screw sleeve to move backward, which in turn moves a T-shaped plate backward. The T-shaped plate then moves a connecting plate backward, which in turn moves an arc-shaped pawl backward, contacting the shear body through an opening. Simultaneously, the connecting plate's backward movement causes a slider to move backward. The slider, in conjunction with a groove, moves backward while the connecting plate stretches a spring, thus securing the shear body. This design solves the problem of existing shears lacking a securing function, which can easily open and cause injury. It reduces the difficulty of operation for the user, increases the applicability of the shears, and improves their practicality.

[0004] When using the aforementioned scissors, it is inconvenient to prune high branches using the scissor body. Directly cutting thicker branches with the scissor body requires greater force to repeatedly squeeze the thicker branches, making the operation cumbersome, greatly reducing pruning efficiency, increasing working time, and increasing the labor intensity of the user. Utility Model Content

[0005] This utility model is designed to solve the aforementioned technical problems by providing a hydraulic pull-out garden pruning shears, which aims to address the issues raised in the background section.

[0006] The technical solution of this utility model is:

[0007] A hydraulic pull-out garden pruning shears includes two blades, a connecting shaft, and two handles. The connecting shaft passes through both blades. The top ends of the two handles are fixedly connected to the two blades respectively. Vertical plates are fixedly connected to both ends of the connecting shaft. A mounting frame is fixedly connected between the two vertical plates. A cutting assembly is located on the rear side of the mounting frame. The cutting assembly includes a side plate, a hydraulic cylinder, and a cutting blade. The side plate is fixedly installed on the rear side of the mounting frame. The cylinder body of the hydraulic cylinder is fixedly connected to the side plate, and the piston rod of the hydraulic cylinder is fixedly connected to the cutting blade. A moving assembly is located on the mounting frame. The moving assembly includes a stepper motor, a forward and reverse lead screw, a slide bar, two sliders, and two pressing plates. The stepper motor is fixedly installed on one side of the mounting frame, and its output shaft is fixedly connected to the forward and reverse lead screw. The two pressing plates are located on opposite sides of the two handles.

[0008] Furthermore, both ends of the positive and negative lead screws are rotatably connected to the mounting frame via bearings, and both the positive and negative lead screws and the slide rods pass through the two sliders. The positive and negative lead screws are threadedly connected to the two sliders, and the bottom ends of the two extrusion plates are fixedly connected to the two sliders respectively.

[0009] Furthermore, a pad is movably provided on one side of the cutting blade, and one side of the pad is fixedly connected to the mounting frame.

[0010] As can be seen, the above technical solution can protect the mounting frame and prevent the cutting edge of the cutting blade from directly contacting the mounting frame.

[0011] Furthermore, two baffles are movably provided on the top of the positive and negative lead screws, and the two baffles are fixedly installed on the front and rear sides inside the mounting frame, respectively.

[0012] As can be seen, the above technical solution can protect the positive and negative lead screws to prevent tree debris from falling on them.

[0013] Furthermore, the stepper motor has a built-in electromagnetic locking structure.

[0014] It can be seen that the above technical solution is designed to facilitate the limiting of the forward and reverse lead screws.

[0015] Furthermore, a telescopic rod that can adjust the height of the mounting frame is fixedly connected to the bottom end of the mounting frame.

[0016] Furthermore, a handle is fixedly connected to the bottom end of the telescopic rod, which serves to facilitate the user's handholding.

[0017] The beneficial effects of the utility model are:

[0018] 1. By pulling the telescopic rod, the distance between the mounting frame and the handle can be adjusted. Then, the cutting blade is moved to the position of the thicker branch. The piston rod on the hydraulic cylinder retracts, which drives the cutting blade to move horizontally and cut the thicker branch. Similarly, the piston rod on the hydraulic cylinder extends, which drives the cutting blade away from the mounting frame. This cycle is repeated. The operation is simple and convenient for cutting thicker branches, which effectively improves the efficiency of pruning and reduces the labor intensity of the user.

[0019] 2. The stepper motor drives the forward and reverse lead screws to rotate. The forward and reverse lead screws can drive the two sliders to move towards each other, thereby driving the two extrusion plates to move towards each other. Since the two vertical plates and the connecting shaft limit the two blades, the two extrusion plates can drive the two blade handles to move the tops of the two blades towards each other. The two blades can cut short thin branches. The structure is simple and has a wide range of applications. Attached Figure Description

[0028] Refer to the instruction manual appendix Figure 1-5 The hydraulic pull-out garden pruning shears of this embodiment include two blade bodies 1, a connecting shaft 2, and two handles 3. The connecting shaft 2 passes through the two blade bodies 1. The top ends of the two handles 3 are fixedly connected to the two blade bodies 1 respectively. Vertical plates 4 are fixedly connected to both ends of the connecting shaft 2. A mounting frame 6 is fixedly connected between the two vertical plates 4. A cutting assembly 7 is provided on the rear side of the mounting frame 6. The cutting assembly 7 includes a side plate 701, a hydraulic cylinder 702, and a cutting blade 703. The side plate 701 is fixedly installed on the rear side of the mounting frame 6. The cylinder body of the pressure cylinder 702 is fixedly connected to the side plate 701, and the piston rod of the hydraulic cylinder 702 is fixedly connected to the cutting blade 703. A moving component 5 is provided on the mounting frame 6. The moving component 5 includes a stepper motor 501, a forward and reverse lead screw 502, a slide rod 503, two sliders 504, and two extrusion plates 505. The stepper motor 501 is fixedly installed on one side of the mounting frame 6, and the output shaft of the stepper motor 501 is fixedly connected to the forward and reverse lead screw 502. The two extrusion plates 505 are located on opposite sides of the two blade holders 3.

[0029] Furthermore, both ends of the positive and negative lead screws 502 are rotatably connected to the mounting frame 6 via bearings, and both the positive and negative lead screws 502 and the slide rods 503 pass through the two sliders 504. The positive and negative lead screws 502 are connected to the two sliders 504 via threads, and the bottom ends of the two extrusion plates 505 are fixedly connected to the two sliders 504 respectively.

[0030] Furthermore, a pad 8 is movably provided on one side of the cutting blade 703, and one side of the pad 8 is fixedly connected to the mounting frame 6.

[0031] Furthermore, the top of the forward and reverse lead screw 502 is movably provided with two baffles 11, and the two baffles 11 are respectively fixedly installed on the front and rear sides inside the mounting frame 6. The stepper motor 501 has a built-in electromagnetic locking structure.

[0032] Furthermore, a telescopic rod 10 that can adjust the height of the mounting frame 6 is fixedly connected to the bottom end of the mounting frame 6, and a handle 9 is fixedly connected to the bottom end of the telescopic rod 10.

[0033] The usage method of this embodiment is as follows:

[0034] In use, the user holds the handle 9 and pulls the telescopic rod 10 to adjust the distance between the mounting frame 6 and the handle 9, positioning the mounting frame 6 near a tree branch at a high point in the garden. The position of the mounting frame 6 is locked by the positioning cap on the telescopic rod 10. Then, the cutting blade 703 is moved to the position of a thicker branch, and the hydraulic cylinder 702 is activated. The piston rod on the hydraulic cylinder 702 retracts, causing the cutting blade 703 to move horizontally and cut the thicker branch. Similarly, the piston rod on the hydraulic cylinder 702 extends, causing the cutting blade 703 to move away from the mounting frame 6. This cycle is repeated, making the operation simple and convenient for cutting thicker branches. This effectively improves pruning efficiency and reduces the user's labor intensity. At the same time, the pad 8 can protect the mounting frame 6, preventing the cutting edge of the cutting blade 703 from directly contacting the mounting frame 6.

[0035] Move the two blades 1 to the position of the thinner branch, start the stepper motor 501, and the stepper motor 501 drives the positive and negative lead screws 502 to rotate. Since the two sliders 504 are threadedly connected to the positive and negative lead screws 502, and the slide rod 503 restricts the rotation of the two sliders 504, the positive and negative lead screws 502 can drive the two sliders 504 to move towards each other, thereby driving the two extrusion plates 505 to move towards each other. Since the two vertical plates 4 and the connecting shaft 2 limit the two blades 1, the two extrusion plates 505 can drive the two blade handles to move the tops of the two blades 1 towards each other. The two blades 1 can cut the thinner branches. The structure is simple and has a wide range of applications. At the same time, the baffle 11 can protect the positive and negative lead screws 502 to prevent tree debris from falling on the positive and negative lead screws 502. It is worth noting that a spring is installed between the two blades 1. The spring can provide restoring force during the use of the two blades 1, ensuring that the two blades 1 can quickly return to the open state after the cutting operation.
