Description

Technical Field

[0001] This utility model belongs to the field of mechanical tool technology, specifically to a right-angle bolt cutter. Background Technology

[0002] Screwdrivers are one of the most commonly used repair tools, found in almost every household. Screwdriver heads come in various shapes, such as flathead, Phillips head, and hexagonal, while the shaft is usually a solid, rigid metal rod that cannot be bent. Although commonly used, screwdrivers have limitations. For example, in actual assembly or repair work, when screwing in or removing screws from complex mechanical parts, if the screw is blocked by an upper component, a straight screwdriver with an inflexible shaft often won't work; screws in dead angles are even more difficult to screw in or out. Utility Model Content

[0003] In view of this, the purpose of this utility model is to overcome the shortcomings of the prior art and provide a right-angle screwdriver. This application provides the following technical solution:

[0004] A right-angle screwdriver includes a handle, a shaft, a bevel gear assembly, and a screwdriver head. One end of the shaft is rotatably connected to the handle, and the other end of the shaft is perpendicular to the screwdriver head. The shaft is connected to the screwdriver head via the bevel gear assembly.

[0005] As an alternative or supplement to the aforementioned right-angle screwdriver, the screwdriver tip is threadedly connected to the bevel gear assembly.

[0006] As an alternative or supplement to the aforementioned right-angle screwdriver, the end of the handle away from the shaft has a storage cavity, the screwdriver head is installed in the storage cavity, and a storage cover is threadedly connected to the storage cavity.

[0007] As an alternative or supplement to the aforementioned right-angle screwdriver, the shank is provided with a bearing, which is disposed between the handle and the shank.

[0008] As an alternative or supplement to the aforementioned right-angle screwdriver, a protective shell is provided at the end of the shank near the screw head.

[0009] As an alternative or supplement to the aforementioned right-angle screwdriver, the outer surface of the handle is provided with anti-slip texture.

[0010] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0011] The right-angle screwdriver of this invention rotates the shank by turning the handle. The rotation of the shank is changed by the bevel gear assembly and transmitted to the screw head, thus realizing the rotation of the screw head. Therefore, compared with the existing screwdrivers, this invention is more convenient and saves time and effort because the right-angle screwdriver can rotate 90 degrees.

[0012] To make the above-mentioned objectives, features and advantages of this application more apparent and understandable, preferred embodiments are described below in detail with reference to the accompanying drawings. Attached Figure Description

[0017] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0018] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0019] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0020] Please refer to Figure 1-2 As shown in the figure, this embodiment provides a right-angle screwdriver, including a handle 1, a shaft 2, a bevel gear assembly 3, and a cutting head 4. One end of the shaft 2 is rotatably connected to the handle 1, and the other end of the shaft 2 is perpendicular to the cutting head 4. The shaft 2 is connected to the cutting head 4 through the bevel gear assembly 3, and the cutting head 4 is threadedly connected to the bevel gear assembly 3. The shaft 2 is provided with a bearing, which is disposed between the handle 1 and the shaft 2. A protective shell 6 is provided at the end of the shaft 2 near the cutting head 4. The outer surface of the handle 1 is provided with anti-slip texture.

[0021] In the above embodiments, such as Figure 1 The diagram shown is a cross-sectional view of the present invention.
