[0001] This utility model relates to the field of garden and horticulture pruning tools, and in particular to a telescopic aerial tree branch saw. Background Technology

[0002] Pruning and harvesting are essential parts of fruit tree growth management. my country ranks first in the world in fruit production, and fruit trees are planted throughout the country, resulting in a large amount of orchard pruning and harvesting work. Pruning can reduce excess branches, increase the effective canopy layer, increase the effective leaf index, improve photosynthesis, control the apical dominance of fruit tree branches, promote flower bud differentiation, and overcome the phenomenon of fruiting on the periphery of the tree and alternate bearing.

[0003] Although my country's harvesting machinery has developed rapidly, and harvesting tools such as harvesters and power pruning tools have been applied, most of the existing tools have been optimized in terms of functionality, but insufficient attention has been paid to the protection of the tools after use. This has led to the tools being damaged by accidental bumps when not in use, and some tools may even cause accidental injury. In response to this technical problem, this application proposes a telescopic high-altitude tree branch saw. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a telescopic high-altitude tree branch saw. When the saw is retracted, it can be conveniently protected by an integrated protective cover, which can also prevent injury from sharp blades. At the same time, the saw adopts a detachable structure, which can be conveniently replaced or removed when not in use for a long time.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A telescopic aerial tree branch saw includes a telescopic handle. The bottom end of the telescopic handle is connected to a rotating component via a telescopic assembly.

The pressure block 13 and the mounting base 11 are slidably connected by two sleeves 12 through a protrusion 20. The protrusion 20 is slidably connected inside the sliding groove. The left and right ends of the mounting base 11 are connected to the sleeves 12 on the left and right sides respectively by bolts for secondary locking. When installing the saw 6, align the positioning hole at its bottom end with the mounting rod 14 and slide it in. Then install and push the pressure block 13. Slide the sleeves 12 along the sliding groove from both sides to initially lock them. Insert the bolts into the insertion holes formed by the sleeves 12 on both sides and the mounting base 11 and tighten them to achieve secondary locking, ensuring that the saw 6 will not loosen under high-intensity vibration.

[0031] Reference Figure 1 and Figure 6A motor housing 15 is fixedly connected to the front side of the blade holder 3. A blade 4 is fixedly connected to the drive end of the motor housing 15. The blade 4 is directly driven by the motor to rotate at a small angle, which drives the blade 4 to cooperate with the cutting edge of the blade holder 3 to perform the cutting action. The blade 4 is located in the middle of the blade holder 3. The top of the blade holder 3 near the blade 4 has a sharp cutting edge structure. The motor housing 15 is equipped with a motor. The motor is a 42V DC brushless motor with a planetary gearbox. It is electrically connected to the motor driver (based on Bluetooth 5.0 communication protocol) at the device end through a waterproof cable. The operator sends commands through a handheld waterproof remote control. After receiving the signal, the driver dynamically adjusts the current output to drive the motor to provide power to the blade 4, so that it cooperates with the cutting edge of the blade holder 3 to complete the cutting action.

[0032] Working principle: When using the saw, rotate the protective cover 2 along the rotating rod 8 to pull out the locking rod 10 at the middle of the inner part of the protective cover 2 from the elastic buckle 9, releasing the protection. Then, slide out the telescopic handles 16, 17, and 18 inside the telescopic handle 1 according to the required height, and engage the spring clips 19 in the corresponding holes. During pruning, insert the branch to be pruned between the blade holder 3 and the blade 4. Start the external controller; the motor inside the motor housing 15 rotates, driving the blade 4 at its drive end to move upwards. Together with the cutting edge structure on the top of the blade holder 3 near the blade 4, the cutting is completed. To disassemble or replace saw 6, unscrew the bolts threaded into the socket 12 and mounting base 11, and pull the sockets 12 at both ends to the left and right respectively. The protrusions 20 on the inner wall of the socket 12 slide out from the grooves of the mounting base 11 and the pressure block 13, releasing the lock on the pressure block 13. Slide the pressure block 13 backward so that the connecting part at the bottom of saw 6 can be removed from the outer wall of the mounting rod 14. If replacement is required, install the new saw 6 onto the outer wall of the mounting rod 14. If not replacement, slide the mounting rod 14 directly into the hole on the back side of the pressure block 13, slide the sockets 12 at both ends in, and insert and tighten the bolts to lock them.
