Technical Field

[0001] This utility model relates to the field of landscaping, and in particular to an auxiliary device for pruning garden trees. Background Technology

[0002] An existing patent (publication number: CN220571065U) proposes a garden pruning device, including a movable rod for supporting and fixing external structures; a storage mechanism connected inside the movable rod for functional use; the storage mechanism includes a fixed block connected to one side of the movable rod, a receiving groove opened at the top of the fixed block, an internal hinge seat slidably connected in the receiving groove, a support rod connected to the internal hinge seat, and an external hinge seat connected to the top of the support rod; it also includes a measuring mechanism rotatably connected to the top of the fixed block to assist the pruning device in measuring the length of tree pruning. However, this device lacks external protective devices, and workers are prone to accidental contact with the blade during operation, which may lead to cuts. In addition, it increases the chance of the blade colliding with hard objects when not in use, causing blade wear and reducing its service life, which has drawbacks. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a garden tree pruning auxiliary device that offers a comfortable and stable grip, facilitates flexible control over the pruning angle and force, ensures the quality and precision of garden tree pruning, meets the pruning needs of branches at different heights, extends the service life of the pruning blades by increasing their protective properties, and prevents accidental contact between the pruning blades and the operator during carrying or storage, thus reducing safety hazards.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A garden tree pruning auxiliary device includes a pruning blade, a protective shell, a fixed support sleeve, a positioning rod, a fixed plate, a drive gear, a crank handle, and a gripping rod. The fixed support sleeve has a fixed shell at its upper end, and the fixed shell has a storage groove adapted to the pruning blade. The storage groove connects to the pruning blade. The pruning blade has a bushing, and the bushing is connected to the protective shell via a shaft. The shaft sequentially connects the protective shell and the pruning blade, and is connected to a motor. The motor is connected to the protective shell. The lower part of the protective shell has a positioning support sleeve. The fixed support sleeve has a slide rail inside, which is adapted to the positioning support sleeve. The positioning support sleeve is connected to the slide rail and slides within the slide rail. The lower end of the fixed support sleeve has an installation support sleeve, which is threadedly connected to an installation block. The installation block has a baffle, the upper part of which is connected to the installation support sleeve, and the lower part of the baffle has a gripping rod. The gripping rod is externally connected to an anti-slip rubber sleeve.

[0006] The mounting sleeve of this utility model has a drive gear fitted inside and a rocker arm fitted outside. The rocker arm has a drive rod that passes through the mounting sleeve and is connected to the drive gear. The drive gear meshes with a driven gear and is connected to the driven gear. The driven gear fits into the mounting sleeve and has a positioning rod that passes through the fixed sleeve and is threaded to the positioning sleeve.

[0007] The fixed support sleeve of this utility model is externally connected to a fixed strip plate. The fixed strip plate has fixed buckles at both ends. The fixed support sleeve is connected to the inner side of the fixed buckles. The fixed buckles have connecting plates on both sides. The screw passes through the connecting plates and the two ends of the screw are connected by threaded nuts. Beneficial effects

[0008] This utility model allows operators to hold the fixed support sleeve stably by gripping the rod and handle, enabling flexible control over the pruning position of the pruning blade. Through the coordinated operation of the drive gear, positioning support rod, and positioning support sleeve, the pruning blade's support height can be adjusted by turning the crank, expanding the range of pruning heights to meet the needs of pruning branches of different heights. No ladder is required for the operation, improving pruning efficiency and safety. In addition to its convenient operation, the appropriate tool length allows for better control of the pruning angle and force, thereby improving the quality and precision of pruning and enhancing the overall effect of garden tree pruning.

[0009] This utility model's protective shell provides semi-enclosed protection for the pruning blade, preventing damage to branches and leaves in the non-cutting direction during pruning operations. When the protective shell is lowered to its maximum extent and the pruning blade is stored in the storage slot, the fixed shell can protect the pruning blade in the non-operational state, preventing the blade from colliding with external hard objects when not in use, reducing blade wear, increasing its service life, and preventing accidental contact between the blade and the operator during carrying or storage, thus reducing safety hazards.

[0010] This utility model offers a comfortable and stable grip, allowing for flexible control over the pruning angle and force. It ensures the quality and precision of pruning garden trees while meeting the pruning needs of branches at different heights. Furthermore, by increasing the protection of the pruning blades, its service life is extended, and it prevents accidental contact between the pruning blades and the operator during carrying or storage, thus reducing safety hazards.
