[0022] 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.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, this utility model provides a technical solution for a multifunctional grape pruning tool, including an electric pruner 1 and a backpack power supply 2. A power cord 3 is provided between the electric pruner 1 and the backpack power supply 2. A sliding support column 5 is fixedly installed at the bottom of the electric pruner 1. A handle 4 is connected to the sliding support column 5. A protective mechanism 6 is installed on the sliding support column 5. A limiting mechanism 7 is installed inside the sliding support column 5. Through the combined use of the protective mechanism 6 and the limiting mechanism 7, foreign objects can be prevented from falling into the user's eyes during the pruning process, making it convenient for the user to prune the grape branches at the top of the grape trellis.

[0024] like Figure 2 , Figure 4 and Figure 5As shown, the protective mechanism 6 includes a positioning ring seat 604 fixedly installed on the sliding support column 5 and a sliding ring seat 605 slidably installed on the sliding support column 5. A film bracket 602 is rotatably installed on the positioning ring seat 604, and a transparent film 601 is fixedly installed on the film bracket 602. A support bracket 603 is provided between the film bracket 602 and the sliding ring seat 605. An installation shaft 606 is rotatably installed on both the positioning ring seat 604 and the sliding ring seat 605. An installation groove 608 is provided on the film bracket 602, and a connecting leg 607 is rotatably installed in the installation groove 608. The lower half of the sliding support column 5 is threaded, and the handle 4 is threaded to the sliding support column 5. A rotating shaft is provided on the connecting leg 607, and the connecting leg 607 is rotatably installed in the installation groove 608 through the rotating shaft.

[0025] Specifically, before pruning the grapevines at the top of the trellis, the sliding ring 605 can be pushed upwards. When this action is performed, the support bracket 603 will correspondingly push the film bracket 602 upwards. As the film bracket 602 expands upwards, it will also cause the transparent film 601 to expand. In this way, when pruning begins, the expanded transparent film 601 will be positioned above the eyes, effectively blocking any foreign objects that may fall during pruning, thus protecting the eyes from injury.

[0026] like Figure 2 , Figure 3 and Figure 6 As shown, the limiting mechanism 7 includes a mechanism housing 702 fixedly installed inside the sliding support column 5. The front end of the mechanism housing 702 is provided with an inlet / outlet hole 701. A reset spring 704 is provided inside the mechanism housing 702. A spring seat 703 is slidably installed inside the mechanism housing 702. A limiting protrusion 705 is fixedly installed on the spring seat 703. A through hole is provided on the sliding support column 5, and the through hole on the sliding support column 5 is aligned with the inlet / outlet hole 701 on the mechanism housing 702.

[0027] Specifically, when the sliding ring seat 605 is moved to the position above the limiting protrusion 705, the return spring 704 will perform its reset action. During this process, the return spring 704, through its own elastic force, will push the limiting protrusion 705 forward, ensuring that the limiting protrusion 705 can extend beyond the outer side of the sliding support 5. In this way, the limiting protrusion 705 will be positioned in the falling path of the sliding ring seat 605, acting as a blockage and thus limiting the downward trend of the sliding ring seat 605. This design ensures that the transparent film 601 can remain open continuously, providing convenience for users and allowing them to easily prune the grapevines at the top of the trellis.

[0028] Working principle: The backpack power supply 2 provides power to the electric pruning device 1, allowing the user to prune the grapevines by hand. Before pruning the grapevines at the top of the trellis, the sliding ring seat 605 can be pushed upwards. When the sliding ring seat 605 is pushed upwards, the support bracket 603 will push the film bracket 602 upwards. After the film bracket 602 is extended upwards, it will open the transparent film 601. When pruning the grapevines at the top of the trellis, the open transparent film 601 will block the user's eyes, preventing foreign objects from falling into the user's eyes during the pruning process. Secondly, when the sliding ring seat 605 is pushed to move above the limiting protrusion 705, the return spring 704 will return to its original position. When the return spring 704 returns to its original position, it will push the limiting protrusion 705 forward, causing the limiting protrusion 705 to extend beyond the sliding support 5 and block the downward path of the sliding ring seat 605, restricting the sliding ring seat 605 from sliding down. This keeps the transparent film 601 in an open state, making it convenient for the user to prune the grapevines at the top of the trellis. Furthermore, the electric pruner 1 of this application features a detachable blade head, comprising two different functional blade heads: a trimming blade head suitable for routine pruning, and a branch trimming blade head particularly suitable for cutting thicker branches. This design allows users to select the appropriate blade head according to their actual needs, thereby improving work efficiency and pruning quality. In addition, the power cord 3 of this application incorporates a steel wire rope, the end of which is securely fixed to the handle 4. This further enhances the connection strength between the cord and the handle, ensuring a more stable connection. This design effectively prevents the risk of the cord breaking due to being pulled by branches during use, thus improving the product's safety and durability.
