Pruning tool for garden maintenance

Abstract

This utility model discloses a garden maintenance pruning tool, belonging to the technical field of pruning tools. It includes a pruning shear frame and pruning shear blades. The pruning shear blades are slidably installed within the pruning shear frame, which has a groove containing a connecting component for magnetically connecting the pruning shear blades. A positioning component for positioning the pruning shear blades is also provided inside the pruning shear frame. This garden maintenance pruning tool allows for convenient disassembly and reassembly of the blades through the installation of a protruding post and a spring. When the pruning shear blades need to be installed, pulling the lifting plate moves the support column upwards, which in turn moves the protruding post on the fixed circular plate upwards. The pruning shear blades are then inserted into the groove. Lowering the lifting plate causes the protruding post to move into the first hole due to the spring's elasticity. The installation of the protruding post and spring not only allows for convenient replacement of the blades when they become dull but also allows for the replacement of blades with different shapes depending on the environment.

A first hole 8 is provided on the trimmer blade 2, and the protruding post 16 is located in both the second hole 13 and the first hole 8. The connecting assembly includes a magnetic plate 10 and a metal plate 14. The metal plate 14 is fixedly installed in the groove 11, and a magnetic plate 10 is fixedly installed at one end of the trimmer blade 2. A suction plate 10 is provided, and the magnetic suction plate 10 is magnetically connected to the metal plate 14. The trimmer shears frame 1 is equipped with a rotating shaft 6, which provides a fulcrum to realize the cutting action. With the acceleration of urbanization and the improvement of residents' requirements for the quality of living environment, the urban green area continues to expand, and the workload of garden maintenance has increased significantly. Pruning is the core link of daily garden management, and the performance of its tools directly affects the work efficiency and quality. Traditional pruning tools mostly adopt a fixed blade design, which is not convenient to replace when the blade becomes dull after a certain period of use. At the same time, it is not possible to replace different blades according to different environments. Therefore, by installing a protruding post 16 and a spring 15, the blade can be easily disassembled. When it is necessary to install the trimmer shears blade 2, the blade can be easily disassembled. During installation, first pull the lifting plate 4, then the lifting plate 4 moves the support column 9 upward, and the support column 9 moves the protruding column 16 on the fixed circular plate 12 upward, bringing the protruding column 16 above the second hole 13. The spring 15 then moves with elastic force. Next, insert the scissor blade 2 into the groove 11, and then the magnetic plate 10 and the metal plate 14 are magnetically connected. Then, lower the lifting plate 4, and the protruding column 16 will enter the first hole 8 through the elastic force of the spring 15, thus completing the installation. To disassemble, repeat this operation. The installation of the protruding column 16 and the spring 15 not only allows for convenient replacement of the blade after it becomes dull, but also allows for the replacement of blades of different shapes according to different environments, improving work efficiency.

[0023] Please see Figures 1-5As shown, the fixing plate 17 is provided with a first threaded hole 18 and a second threaded hole 19. A screwing plate 3 is provided above the trimmer handle 7, and the screwing plate 3 can be threadedly connected to both the first threaded hole 18 and the second threaded hole 19. A baffle 5 is fixedly installed on the fixing plate 17 to prevent the trimmer handle 7 from falling off during sliding. In order to facilitate the carrying of the trimmer tool, the trimmer handle 7 is telescopically extended by using the first threaded hole 18 and the second threaded hole 19 in conjunction with the screwing plate 3. When it is necessary to retract the trimmer handle 7, the screwing plate 3 is screwed, so that the threaded post on the screwing plate 3 is screwed out of the second threaded hole 19, allowing the trimmer handle 7 to slide. Then it slides above the first threaded hole 18, so that the threaded post on the screwing plate 3 is aligned with the first threaded hole 18. The screwing plate 3 is then screwed again to allow the threaded post to enter the first threaded hole 18 for fixation, completing the retraction. This makes the trimmer tool easy to carry and store.

[0024] As a technical optimization of this utility model, when it is necessary to install the trimmer blade 2, first pull the lifting plate 4, then the lifting plate 4 drives the support column 9 to move upward, the support column 9 drives the protrusion 16 on the fixed circular plate 12 to move upward, bringing the protrusion 16 above the second hole 13. The spring 15 performs elastic movement, then the trimmer blade 2 is inserted into the groove 11. Then the magnetic plate 10 and the metal plate 14 are magnetically connected. Then the lifting plate 4 is lowered, and the protrusion 16 will enter the first hole 8 through the elastic movement of the spring 15, thus completing the installation. To disassemble, simply repeat this operation. The protruding post 16 and spring 15 not only allow for convenient replacement of the blade after it becomes dull, but also enable the replacement of blades with different shapes according to different environments, improving work efficiency. When it is necessary to retract the handle 7 of the trimmer, turn the rotating plate 3 to unscrew the threaded post on the rotating plate 3 from the second threaded hole 19, allowing the handle 7 of the trimmer to slide. Then slide it above the first threaded hole 18, align the threaded post on the rotating plate 3 with the first threaded hole 18, and then turn the rotating plate 3 to allow the threaded post to enter the first threaded hole 18 for fixation, completing the retraction. This makes the trimmer tool easy to carry and store.
