Description

Technical Field

[0001] This utility model relates to the field of gardening tools technology, and in particular to a pruning shear cover. Background Technology

[0002] With the advancement of science and technology and the deepening research in plant physiology, people have gradually come to understand the laws of plant growth and development, the principles of photosynthesis, and the regulatory role of hormones in plant growth. This knowledge provides a theoretical basis for modern pruning techniques, making pruning no longer merely an experience-based operation, but a scientific and reasonable process based on the physiological characteristics of plants. According to the principle of apical dominance, pruning terminal buds can promote the growth of lateral branches, thus making the plant more lush. After understanding the importance of photosynthesis to plant growth, people will prune branches reasonably to ensure that all parts of the plant can receive sufficient light and improve the efficiency of photosynthesis. Pruning shears, as a tool widely used in the field of horticulture, play a key role in pruning the branches of flowers and trees, helping them grow according to the grower's expectations.

[0003] Different plant species have vastly different pruning requirements, necessitating customized pruning plans for each plant. This places higher demands on the professional knowledge and skills of pruning technicians. In large-scale agricultural and forestry production, pruning speed is slow and quality cannot keep up. Existing common pruning shears have diverse structures, some resembling ordinary scissors, consisting of two blades connected by a cross shaft, including a fixed handle, a movable handle, and the shear body. The movable handle has a collar that holds the fixed and movable handles in a closed state, using leverage to prune. However, these types of pruning shears have revealed many problems in actual use. When the worker uses the collar to close the pruning shears, the length of the collar on the movable handle is greater than the distance between the fixed and movable handles when the pruning shears are fully closed, making it difficult for the movable handle to close completely, thus creating a safety hazard. Regarding the blade changing design, although some pruning shears have blade changing holes and covers, in actual operation, the blade changing process may be cumbersome and require auxiliary tools, affecting work efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a pruning shear cover plate, which aims to improve the problems of low safety factor and difficulty in changing blades in the prior art.

[0039] Working principle: Hold the handle 23 and turn on the switch 25 on the left side. This will start the motor 1 to control the rotation of the first rotating column 3, which will drive the half gear 4 to rotate, causing the round gear 5 to rotate. This will drive the turntable 7 to rotate through the second rotating column 6, causing the rear guide column 9 to rotate with the disc. This will allow the left side of the swing column 10 to move back and forth. Due to the characteristics of the half gear 4, the swing column 10 will pause, so that the bottom arc blade 13 will not trim continuously. This makes it easier for the user to use, improves efficiency, and increases safety.

[0040] When the curved blade 13 needs to be replaced, simply turn screw 203 to dislodge it from the front and rear sides of the fixing post 201, separating housing 204 and housing 205, and also separating the small round groove 208 and the locking post 207. Then, simply turn knob 206 to dislodge the curved blade 13. Replace it with a new curved blade 13 and install it, then tighten knob 206 to complete the replacement. The curved blade 13 will wear down after long-term use. This structure allows users to replace the old curved blade 13, making it convenient for users.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
