It includes a limiting box, an internal gripping component, a long rod on the bottom surface of the limiting box, two reinforcing rods on the outer surface of the long rod with their tops connected to the bottom surface of the limiting box, and an anti-slip sleeve on the outer surface of the long rod. A pruning component is installed on the back of the limiting box. The gripping component includes a motor fixedly embedded in the outer surface of the limiting box, with a positive and negative lead screw fixedly connected to the output end of the motor. Through the coordinated arrangement of the limiting box, gripping component, long rod, reinforcing rods, anti-slip sleeve, and pruning component, the device can prune plants using the pruning component and grab the pruned branches using the gripping component, preventing branches from falling and injuring workers after being cut from a height, thus reducing the safety hazards during use.

[0003] The aforementioned pruning device requires multiple motors for operation, has a relatively complex structure, and its weight is concentrated at the top of the long pole, making it difficult for personnel to hold while standing on the ground. Utility Model Content

[0004] To address the shortcomings of the comparative literature, this invention provides a high-altitude green plant maintenance and pruning device, which solves the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a high-altitude green plant maintenance and pruning device, including a long pole, a fixed frame fixedly installed at the bottom of the long pole, a motor fixedly installed on the inner side of the fixed frame, and a battery pack electrically connected to the motor fixedly connected at the bottom of the fixed frame, a mounting frame provided at the top of the long pole, a lead screw rotatably connected to the bottom of the long pole inside the mounting frame, a mounting block located inside the mounting frame threaded on the outer side of the top of the lead screw, and the outer side of the bottom end of the lead screw extending outside the long pole fixedly connected to the output shaft of the motor through a bushing, a blade fixedly installed inside the mounting block by bolts, a guide groove adapted to the mounting block provided inside the mounting frame, a guide rod located outside the lead screw fixedly installed inside the mounting frame, a lower gripping frame movably sleeved on the outer side of the guide rod, an upper gripping frame located above the lower gripping frame fixedly installed inside the mounting frame, and a pushing mechanism installed between the mounting block and the lower gripping frame;

[0006] The pushing mechanism includes a fixed rod that is fixedly fitted inside the mounting block. A connecting plate that is fixedly installed on the lower gripping frame is movably sleeved on the outer side of the top of the fixed rod. A spring located between the mounting block and the connecting plate is fitted on the outer side of the fixed rod, and a retaining ring is engaged on the outer side of the top of the fixed rod that extends out of the connecting plate.

[0007] Preferably, there are two lower gripping frames and two upper gripping frames, and the lower gripping frames and the upper gripping frames are symmetrically distributed on both sides of the blade.

[0008] Preferably, the outer side of the upper gripping frame is provided with a reinforcing block that is fixedly connected to the top of the mounting frame.

[0009] Preferably, reinforcing plates are fixedly installed on both sides of the mounting bracket.

[0010] This utility model has the following advantages:

[0011] 1. Driven by the motor, the mounting block moves upward along the axis of the lead screw, compressing the spring. The elastic force generated by the spring then moves the lower gripping frame upward, clamping and fixing the branch to be pruned between the lower and upper gripping frames. As the mounting block continues to move upward, the blade cuts the branch held between the lower and upper gripping frames. This structure allows the device to perform branch clamping and pruning operations under the drive of a single motor, and its structure is relatively simple.

[0012] 2. By mounting the motor and battery pack at the bottom of the long pole, the weight of the device is concentrated at the bottom of the long pole, making it easier for people to hold the device on the ground. Attached Figure Description

Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1 to 5 A high-altitude green plant maintenance and pruning device includes a long pole 1, a fixing frame 2 fixedly installed at the bottom of the long pole 1, a motor 3 fixedly installed inside the fixing frame 2, and a battery pack 4 electrically connected to the motor 3 fixedly connected to the bottom of the fixing frame 2. A mounting frame 5 is provided at the top of the long pole 1, and a lead screw 6 rotatably connected to the bottom of the long pole 1 is rotatably connected inside the mounting frame 5. A mounting block 7 located inside the mounting frame 5 is threaded onto the outer side of the top of the lead screw 6. The outer side of the bottom end of the lead screw 6 extending outside the long pole 1 is fixedly sleeved with the output shaft of the motor 3 through a bushing. The blade 9 is fixedly installed inside the mounting block 7 by bolts 8. The mounting frame 5 is provided with a guide groove 10 that matches the mounting block 7. The guide groove 10 can limit and guide the mounting block 7, so that the screw 6 can drive the mounting block 7 to move along the axial direction of the screw 6 during rotation. The mounting frame 5 is fixedly fitted with a guide rod 11 located outside the screw 6. The lower gripping frame 12 is movably sleeved on the outside of the guide rod 11. The upper gripping frame 13 located above the lower gripping frame 12 is fixedly installed on the inner side of the mounting frame 5. A pushing mechanism 14 is installed between the mounting block 7 and the lower gripping frame 12.

[0021] The pushing mechanism 14 includes a fixed rod 141 fixedly fitted inside the mounting block 7. A connecting plate 142 fixedly mounted on the lower gripping frame 12 is movably sleeved on the outer side of the top end of the fixed rod 141. A spring 143 is fitted on the outer side of the fixed rod 141 between the mounting block 7 and the connecting plate 142. The elastic force generated by the spring 143 can push the lower gripping frame 12 upward along the axial direction of the guide rod 11 through the connecting plate 142, thereby facilitating the clamping of the tree branch between the lower gripping frame 12 and the upper gripping frame 13. A retaining ring 144 is engaged on the outer side of the top end of the fixed rod 141 extending outside the connecting plate 142. The retaining ring 144 can limit the connection plate 142, so that after the mounting block 7 moves downward and resets under the drive of the motor 3, the retaining ring 144 can drive the lower gripping frame 12 to reset.

[0022] The device has two lower gripping frames 12 and two upper gripping frames 13, and the blades 9 are symmetrically distributed on both sides of the lower gripping frames 12 and the upper gripping frames 13. This structure allows the branches to be subjected to force on both sides during the clamping and pruning operation, thereby reducing the force acting on the long rod 1, making it easier for personnel to hold the device on the ground using the long rod 1.

[0023] The upper gripping frame 13 has a reinforcing block 15 fixedly connected to the top of the mounting frame 5 on its outer side. The reinforcing block 15 can increase the structural strength of the upper gripping frame 13, making it less prone to bending deformation when subjected to external forces. In turn, the lower gripping frame 12 and the upper gripping frame 13 can cooperate to clamp the branches and the blade 9 can cooperate with the upper gripping frame 13 to prune the branches.

[0024] The mounting frame 5 is fixedly installed with reinforcing plates 16 on both sides. The reinforcing plates 16 can increase the structural strength of the mounting frame 5, so that the mounting frame 5 is not easily bent or deformed by external forces when the device is pruning branches with the blade 9.

[0025] Working principle: The upper gripping frame 13 is suspended on the branch to be pruned. The motor 3 is started, and the motor 3 drives the lead screw 6 to rotate. The rotation of the lead screw 6 drives the mounting block 7 to move upward along the axis of the lead screw 6. At the same time, the spring 143 is compressed, which drives the lower gripping frame 12 to move upward along the axis of the guide rod 11. The elastic force generated by the spring 143 clamps and fixes the branch between the lower gripping frame 12 and the upper gripping frame 13. As the mounting block 7 continues to move upward, the blade 9 cuts the branch clamped between the lower gripping frame 12 and the upper gripping frame 13.

[0026] After the branch is cut, the motor 3 is started to drive in reverse. The motor 3 drives the lead screw 6 to rotate in reverse and at the same time drives the mounting block 7 to reset. As the mounting block 7 continues to move down, the fixing rod 141 and the retaining ring 144 drive the lower gripping frame 12 to move down and reset. When the mounting block 7 reaches the lowest point, the motor 3 is turned off.
