Technical Field

[0001] This utility model relates to the field of hand tools, and in particular to a spin-formed detachable tool. Background Technology

[0002] In gardening and outdoor activities, tools are commonly used. Some of these tools have blades. Most tools are fixed, folding, or telescopic structures, and the blades cannot be disassembled. When a blade is damaged, the entire tool must be purchased, which is wasteful. Furthermore, it is not possible to replace the blades with different functions according to the needs of use, which has certain limitations. Utility Model Content

[0003] The purpose of this utility model is to address the problems existing in the background technology by proposing a spinning-type detachable tool that is easy to disassemble, allows for individual replacement of the blade when it is damaged, has low cost, and can install different functional blades along the axial or transverse direction according to the needs of use, making it flexible in use.

[0004] The present invention provides a spinning-type detachable tool, comprising a blade, an outer sleeve, an inner sleeve, and a spinning cylinder. The outer sleeve has a forward-facing strip-shaped notch I, an external thread on the outer circumferential surface of the front section, a limiting hole in the front section, and an internal thread on the inner side of the outer sleeve. The inner sleeve is threaded to the inner side of the outer sleeve via the internal thread and has a forward-facing strip-shaped notch II. The spinning cylinder is threaded onto the external thread of the outer sleeve, and the spinning cylinder has transversely distributed insertion holes for securing a blade installed axially along the spinning cylinder at the strip-shaped notch II or for securing a blade transversely inserted into the insertion holes.

[0020] like Figures 1-5 As shown in the figure, the spin-forming detachable tool proposed in this embodiment includes a blade, an outer sleeve 1, an inner sleeve 2, and a spin-forming cylinder 3.

[0021] The outer sleeve 1 has two forward-facing, evenly spaced strip-shaped notches 102. The outer circumferential surface of the front section of the outer sleeve 1 has external threads, and the front section has a limiting hole 101. The limiting hole 101 is as follows: Figure 2 The "T" shaped hole shown or as Figure 3 The “L”-shaped holes shown have end dimensions of the limiting holes 101 that are larger than the front opening dimensions. Two limiting holes 101 are evenly arranged around the central axis of the outer sleeve 1. The two strip-shaped notches 102 and the two limiting holes 101 are evenly distributed, resulting in a regular structure. The inner side of the outer sleeve 1 has internal threads, and the outer periphery of the front end of the outer sleeve 1 has a tapered surface.

[0022] The inner sleeve 2 is connected to the inner side of the outer sleeve 1 by an internal thread. It has a strip-shaped notch 201 with the opening facing forward. Four strip-shaped notches 201 are evenly arranged around the central axis of the inner sleeve 2, forming a four-segment circumferential strip structure that can be squeezed inward.

[0023] The spinning cylinder 3 is threaded onto the external thread of the outer sleeve 1. The spinning cylinder 3 has two transversely distributed insertion holes 301, which are evenly distributed around the central axis of the spinning cylinder 3. The inner circumference of the front end of the spinning cylinder 3 has a second conical surface with a first extrusion conical surface. The spinning cylinder 3 can fasten the blade (blade 4) installed along the axial direction of the spinning cylinder 3 at the second strip notch 201, or fasten the blade (blade 5) that is transversely inserted into the inner side of the insertion hole 301.

[0024] The blade 4 has protruding bosses 41 on both sides of its end. One side of the front of the blade 4 is sharpened, and the other side is serrated. When installing the blade 4 axially, the inner sleeve 2 is first screwed onto the inner side of the outer sleeve 1. The limiting hole 101 ("T" shaped hole or "L" shaped hole) is roughly aligned with the strip notch 102. Then, the blade 4 is inserted into the inner side of the strip notch 102, which is also inserted into the inner side of the limiting hole 101, until the bosses 41 are located behind the limiting hole 101. Then, the blade 4 is rotated, and the blade 4 drives the inner sleeve 2 to rotate backward. The bosses 41 at the end of the blade 4 are locked in the misaligned part at the rear of the limiting hole 101. Finally, the spinning cylinder 3, which was originally fitted on the outer sleeve 1, is rotated backward. The front end of the spinning cylinder 3 presses the front end of the outer sleeve 1 inward, and the outer sleeve 1 then presses the front part of the inner sleeve 2 inward. The inner sleeve 2 presses the end of the blade 4 firmly.

[0025] like Figure 4 As shown, the width of the end of the second blade 5 is smaller than the width of the front section, and the front end is sharpened. When installing the second blade 5 horizontally, insert the end of the second blade 5 into the insertion hole 301, and then screw the spinning cylinder 3 backward at the external thread of the front section of the outer sleeve 1 to press the end of the second blade 5 tightly against the front end of the outer sleeve 1. When using the second blade 5, the second blade 5 is not easy to fall off from the inside of the insertion hole 301.

[0026] Furthermore, if only two insertion holes 301 are provided, the length of the insertion holes 301 will be too large, resulting in low structural strength of the front section of the spinning cylinder 3. Therefore, if... Figure 5 As shown, the spinning cylinder 3 has a connecting part 31 added to the middle of the insertion hole 301, which divides the insertion hole 301 into two parts and improves the structural strength of the front section of the spinning cylinder 3. However, the shape of the blade 2 5 that is adapted to it is changed at this time. A groove needs to be made at the end of the blade 2 5 so that the connecting part 31 can be inserted. It can still be ensured that the end of the blade 2 5 extends into the inside of the insertion hole 301, and when the spinning cylinder 3 is rotated backward, the blade 2 5 can be pressed tightly against the front end of the outer sleeve 1. At this time, the inner sleeve 2 can be pre-screwed into the inside of the outer sleeve 1.

[0027] To improve the anti-slip performance of this tool during operation, anti-slip textures are provided on the rear section of the outer sleeve 1 and the outer circumference of the spinning cylinder 3.

[0028] This embodiment is easy to disassemble, allowing for individual blade replacement when damaged, resulting in low cost. It allows for flexible installation of either blade 4 axially or blade 5 laterally, depending on usage requirements. When installing different blades, the blades are secured by rotating the spinning cylinder 3 backwards, making operation convenient. Specifically, the spinning cylinder 3 indirectly presses the end of blade 4 by squeezing the inner outer sleeve 1 and inner sleeve 2, while directly pressing the end of blade 5 against the front end of the outer sleeve 1.

[0029] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
