[0002] Garden shears are a tool used to trim and tidy up plants, trees, shrubs and other garden plants. It usually consists of two sharp blades and a handle. The blades of the garden shears can be opened and closed by operating the handle to cut the branches or leaves of the plant. The design of the garden shears makes the pruning work more precise and convenient, which can help gardening enthusiasts and professional gardeners to prune and shape plants.
[0003] For example, the Chinese patent with application number 202321516424.4 discloses a garden shear for landscaping, comprising two transmission rods, one end of each of the two transmission rods is provided with a threaded hole, the inner walls of the two threaded holes are threadedly connected with a threaded rod, and one end of each of the two threaded rods is fixedly connected with a connecting block. The advantage of the utility model is that through the coordinated arrangement of the threaded hole, threaded rod, connecting block, scissors body, storage shell, support shaft, saw blade, fixed socket, fixed spring, pull block and fixed plug rod, the scissors body can be separated from the transmission rod when pruning thicker branches, and the saw blade can be extended, so that the thicker branches can be cut by the saw blade, so that the garden shear structure increases the function of saw blade cutting, avoids the more troublesome operation of pruning thicker branches due to not carrying a saw blade, and thus reduces the labor intensity of the operator.
[0004] However, in actual use, the blades of the garden shears will be worn to varying degrees during long-term use. The blades in this solution cannot be replaced, resulting in the entire garden shears being unable to be used normally after the blades are worn, which wastes financial resources. At the same time, the garden shears in this solution cannot adjust the length, and the scope of application has certain limitations. Utility Model Content

[0034] Example 2
[0035] like Figure 1-4 As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the other end of the handle 1 away from the fixing assembly 4 is fixedly connected with an adjustment mechanism 5, and the adjustment mechanism 5 includes a hollow handle 501, a bearing 502, a screw rod 503, a slider 504, a telescopic cylinder 505, a limiting cylinder 506, a vertical groove 507, and an adjustment cap 508. The bottom of the hollow handle 501 is fixedly connected with the bearing 502, the inner part of the bearing 502 is movably connected with the screw rod 503, and the outer part of the screw rod 503 is movably connected with A slider 504, a telescopic cylinder 505 is fixedly connected to the top of the slider 504, a vertical groove 507 is opened inside the telescopic cylinder 505, the end of the screw rod 503 is fixedly connected to the limiting cylinder 506, the other end of the screw rod 503 away from the limiting cylinder 506 is fixedly connected to the adjusting cap 508, two groups of handles 1 are provided, the two groups of handles 1 are movably connected by rivets 2, the other end of the protrusion 402 is fixedly connected to the trimming blade 3, the protrusion 402 and the fixed frame 406 are opened with slots, and the slots are adapted to the pin 403.
[0036] In this embodiment, the adjustment mechanism 5 in the scheme can adjust the length of the garden shears, making it convenient for use in different pruning scenarios and improving the applicability of the product. The two sets of handles 1 in the scheme are movably connected, and the angle between the two can be adjusted, so that the two sets of pruning blades 3 are close to each other to prune branches. The pin 403 in the scheme can be fixed in the slot of the protrusion 402 through the reaction force of the first return spring 405, thereby fixing the pruning blade 3.
[0037] Example 3
[0038] like Figure 1-4As shown, on the basis of Example 1 and Example 2, the utility model provides a technical solution: preferably, the adjustment mechanism 5 is provided with two groups, the outside of the hollow handle 501 is provided with anti-slip grooves 8, the inner side wall of the telescopic cylinder 505 is fixedly connected with a fixed block 6, the side wall of the fixed block 6 is fixedly connected with a second reset spring 7, the screw rod 503 passes through the hollow handle 501 and extends into the interior of the telescopic cylinder 505, the telescopic cylinder 505 is movably connected to the hollow handle 501, the interior of the slider 504 is provided with a thread compatible with the screw rod 503, and the diameter of the limiting cylinder 506 is larger than the diameter of the internal opening of the slider 504.

[0040] The following is a detailed description of the working principle of the garden shears specially used for landscaping.
[0041] like Figure 1-4 As shown, when in use, the two hollow handles 501 are held and force is applied internally. Since the two sets of knife handles 1 are hinged by the rivets 2, the two pruning blades 3 are brought close to each other to prune the branches. At the same time, the second return spring 7 is compressed and stores force. When the user stops applying force to the hollow handle 501, the hollow handle 501 is reset and the pruning blades 3 are separated. When the pruning blades 3 need to be replaced, the pin cap 407 is pulled out to separate the latch pin 403 from the protrusion 402. The latch pin 403 moves upward and drives the limit plate 404 to squeeze the first return spring 405 upward to store force. At this time, the pin cap 407 is pulled out to separate the latch pin 403 from the protrusion 402. The protrusion 402 with the pruning blade 3 is inserted into the groove 401, the pin cap 407 is loosened, the first reset spring 405 is reset, and the pin 403 is inserted into the groove 401 inside the protrusion 402, so that the pruning blade 3 can be quickly replaced. When the length of the garden shears needs to be adjusted, the adjusting cap 508 is rotated to make the screw rod 503 rotate inside the bearing 502, so that the slider 504 drives the telescopic cylinder 505 to move up and down. When it moves upward to the farthest point, the limiting cylinder 506 will block the main slider 504 to prevent the telescopic cylinder 505 from falling off, and finally the length of the garden shears can be adjusted.
[0042] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
