Abstract
Description
Technical Field
[0001] This utility model relates to the field of grafting tools, and more particularly to a batch cutting device for grafting. Background Technology
[0002] Grafting often involves batch grafting, and the grafting branches usually need to be cut before grafting. Currently, there are two main types of tools used for cutting grafting branches. One is a general-purpose garden knife. This method requires manually cutting the branches into the appropriate shape, which is inefficient and not suitable for batch operations.
[0003] To address this issue, existing technologies have developed standardized pruning tools tailored to different grafting methods. However, these tools have significant drawbacks. Firstly, they are mostly single-handed pliers, limiting the diameter of branches they can cut. They are generally only suitable for cutting branches with a diameter of no more than 5mm, and are particularly difficult to use when cutting harder branches. Secondly, the devices are limited by size and strength, and are inconvenient to sharpen when the blade is dull, resulting in a short lifespan. Currently, there is no corresponding solution to this problem. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a grafting batch cutting device that is simple in structure, labor-saving to use, and especially suitable for batch grafting.
[0005] The equipment includes a support frame, which serves as the assembly base for the equipment.
[0006] A pressure bar is threaded through the bracket, and a cutting tool is provided at the bottom of the pressure bar;
[0007] The pressure rod is rotatably equipped with a pulley, the pulley is equipped with a movable arm, and the movable arm is hinged to the bracket.
[0008] A return spring is also provided between the pressure rod and the bracket.
[0009] The effect achieved is that when the boom presses down to contact the pulley, the pressure rod sinks as the boom presses down, causing the cutter to sink and complete the cutting action. The pulley on the pressure rod makes the boom's downward stroke smoother. Furthermore, the return spring ensures the pressure rod automatically returns to its original position after pressing down.
[0010] The beneficial effects of this utility model are: it solves the drawbacks of existing grafting branch cutting tools, enabling wider application of branches, and is especially labor-saving to use. Furthermore, the equipment has high overall strength, and the blades can be detached and individually sharpened. It has a longer service life and a wider range of applications.

[0016] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation
[0017] Reference Figure 1 , Figure 2 The present invention provides a batch cutting device for grafting, which includes a support frame, and the support frame is the assembly base of the device.
[0018] A pressure rod 7 is threaded through the bracket, and a cutting tool 8 is provided at the bottom of the pressure rod 7;
[0019] The pressure rod 7 is rotatably equipped with a pulley 4, and the pulley 4 is equipped with a movable arm 3, which is hinged to the bracket.
[0020] A return spring 5 is also provided between the pressure rod 7 and the bracket.
[0021] The effect achieved is that when the boom 3 presses down to contact the pulley 4, the pressure rod 7 sinks as the boom 3 presses down, which in turn drives the cutter to sink and perform the cutting action. The pulley 4 on the pressure rod 7 makes the downward stroke of the boom 3 smoother. Furthermore, the pressure rod 7 can automatically return to its original position after pressing down, thanks to the return spring 5.
[0022] In Example 1, the bracket includes a base plate 1, a rear baffle 2 integrally connected to the rear of the base plate 1, and an assembly base plate 6 disposed in front of the rear baffle 2.
[0023] The effect achieved in this way is to increase the intensity of equipment use.
[0024] Furthermore, the base plate 1 is provided with a recessed countersunk hole, and an anvil 9 is movably disposed in the countersunk hole, and the position of the countersunk hole corresponds to the cutting tool 8.
[0025] Preferably, the cutting board 9 is a wooden cutting board 9.
[0026] This achieves the effect of facilitating the application of force during the cutting action.
[0027] In Example 2, the pressure rod 7 is a spline rod, and the mounting base plate 6 is provided with a corresponding spline hole, through which the pressure rod 7 passes.
[0028] The effect achieved is that the pressure rod 7 stops rotating, meaning that the pressure rod 7 does not rotate during the pressing process.
[0029] Example 3, refer to the accompanying drawings in the specification. Figure 2 or Figure 3 The cutting tool 8 includes a base 81, and the base 81 and the bottom of the pressure rod 7 are respectively provided with pin holes, and a pin is passed through the base 81 and the pressure rod 7.
[0030] A cutter 82 is integrally connected to the base 81, and the cutting edge of the cutter 82 is facing downward.
[0031] Preferably, the cutter 82 is provided with various sizes and forms, such as crimping, tongue connection, and other specific forms, as well as corresponding specific size specifications for different forms.
[0032] In Example 4, a pulley 4 assembly frame is provided on the pressure rod 7, and the pulley 4 assembly frame is in the form of channel steel;
[0033] The return spring 5 is disposed between the pulley 4 assembly bridge and the assembly base plate 6, and is sleeved on the pressure rod 7.
[0034] The effect achieved in this way is to optimize the assembly structure.
[0035] Furthermore, the pulley 4 is a V-grooved pulley.
[0036] The result is that the downward stroke of boom 3 is more stable and smooth.
[0037] In Example 5, the pressure rod 7 is hinged to the front of the rear baffle 2 and is in the form of an elongated tube; an anti-slip rubber sleeve is provided at the end of the pressure rod 7.
[0038] This makes it easier to generate force when pressing down.
[0039] Preferably, a force-adding rod is also movably provided on the pressure rod 7.
[0040] The effect achieved in this way is to lengthen the lever arm, making it more labor-saving.
