Description

Technical Field

[0001] This application relates to the field of garden tools technology, and in particular to a high-branch shears. Background Technology

[0002] Pruning shears (also known as pruning saws) are designed to achieve the cutting action of two blades with teeth, while simultaneously allowing the two blades to rotate relative to the handle of the pruning shears at the required angle to adapt to the growth shape of branches and the desired appearance trimming. When the pruning shears are not in use, the two blades are exposed to the outside environment, making them susceptible to wear from external objects. Protective sleeves are provided to enclose the two blades, protecting them from wear. However, due to the length of the blades, the pruning shears take up a lot of space during storage, and external impacts can cause the protective sleeves to collide with the blades, reducing the lifespan of the pruning shears. Utility Model Content

[0003] The purpose of this utility model is to provide a high-branch pruning shear in response to the defects and deficiencies of the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] The device includes a protective sleeve, a rotating part, a housing, and a support rod. The rotating part includes a rotating shell and a blade part. One end of the blade part is installed inside one end of the rotating shell. The protective sleeve is fitted over the other end of the blade part. One side of the rotating shell is rotatably connected to one side of the housing. One end of the support rod is fixed to one end of the housing. A drive motor is installed inside the housing. The output shaft of the drive motor passes through the rotating shell to drive the blade part to work.

[0006] Preferably, a locking block is provided between the outer shell and the rotating shell. One end of the locking block is rotatably connected to the side wall of the outer shell, and the side wall of the rotating shell is provided with a locking groove. The other end of the locking block is engaged and fixed in the locking groove.

[0007] Preferably, the side wall of the outer casing is provided with a rotating groove, and one end of the locking block is rotatably connected to the rotating groove.

[0008] Preferably, a torsion spring is fitted on the rotating shaft of the locking block, and the torsion spring drives the other end of the locking block to be inserted into the locking groove.

[0009] Preferably, the rotating housing has a balance plate at the end away from the blade section.

[0010] Preferably, the side wall of the protective sleeve is provided with a first locking buckle, which can be fastened to the periphery of the support rod.

[0011] Preferably, the side wall of the balance plate is provided with a second locking buckle, which can be fastened to the periphery of the support rod.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. When the pruning shears are not in use, first put the protective cover around one end of the blade, then rotate the rotating shell 180° so that the protective cover is on one side of the support rod. Then, under the action of the torsion spring, one end of the locking block is inserted and fixed into the locking groove, locking the outer shell and the rotating shell. This reduces the length of the pruning shears and allows the protective cover to be on one side of the support rod, so that the protective cover is not subjected to external forces and the blade is not impacted by the protective cover, thus improving the stability of the pruning shears.

[0014] 2. The balance plate is located at the end of the rotating shell furthest from the blade section. Under the action of the balance plate, the rotating shell can be prevented from tilting under the pull of gravity, thus improving the stability of the rotating part.

[0015] 3. With the first or second locking buckle interlocking with the support rod, the stability of the rotating part of the high-pole shears in both working and non-working states can be ensured. Attached Figure Description

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] This application discloses a high-branch pruning shear.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The device includes a protective sleeve 1, a rotating part 2, a housing 3, and a support rod 4. The rotating part 2 includes a rotating shell 5 and a blade part 6. One end of the blade part 6 is inserted into one end of the rotating shell 5. A bearing is installed and fixed inside one side of the rotating shell 5. A convex ring is integrally provided on one side of the housing 3. The convex ring of the housing 3 is inserted and fixed to the inner circumference of the bearing. A drive motor is installed inside the housing 3. The output end of the drive motor passes through the convex ring, is inserted into the rotating shell 5, and is connected to the blade part 6. The protective sleeve 1 is fitted around the outer circumference of the blade part 6.

[0024] Reference Figure 4 The outer shell 3 has a rotating groove 8 on the circumference of the side near the rotating shell 5. A locking block 9 is rotatably connected in the rotating groove 8. Two locking grooves 10 are evenly opened on the side wall of the rotating shell 5. One end of the locking block 9 is snapped and fixed in one of the locking grooves 10.

[0025] A torsion spring 11 is sleeved around the rotating shaft of the locking block 9. One end of the torsion spring 11 abuts against the side wall of the rotating groove 8 and the other end of the torsion spring 11 abuts against the side wall of the locking block 9. The torsion spring 11 drives one end of the locking block 9 to rotate into the locking groove 10.

[0026] Reference Figure 2 A balance plate 12 is snapped and fixed at the end of the rotating shell 5 away from the blade part 6. Under the action of the balance plate 12, the rotating shell 5 can be prevented from tilting under the pull of gravity on the blade part 6.

[0027] Reference Figure 1 The protective sleeve 1 has a first locking buckle 13 installed and fixed on its side wall. The first locking buckle 13 includes a first mounting base 14 and a first fixing ring 15. The first fixing ring 15 is arc-shaped and its side wall is welded and fixed to the first mounting base 14. The balance plate 12 has a second locking buckle 16 installed and fixed on its side wall. The second locking buckle 16 includes a second mounting base 17 and a second fixing ring 18. The second fixing ring 18 is arc-shaped and its side wall is welded and fixed to the second mounting base 17. The first fixing ring 15 and the second fixing ring 18 can be respectively clamped to the periphery of the support rod 4.
