Description

Technical Field

[0001] This utility model relates to the field of hardware tool technology, specifically to a shank drill bit. Background Technology

[0002] A drill bit is a type of shank-mounted drill tool used to create holes in workpieces or rocks. Drill bits have a wide range of applications, including on drilling machines, lathes, milling machines, and electric drills. There are many types of drill bits, and the hand drill is one of them. Hand drills allow users to easily drill holes in target workpieces when there are no power tools or electricity, and they are especially used in woodworking. Current hand drills generally have a special structure, which makes them relatively less functional and requires more effort to drill. Utility Model Content

[0003] In view of the prior art, the purpose of this utility model is to provide a shank drill bit with a storage and manual drilling handle design, which can facilitate manual drilling by users.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a shank drill bit, including a shank and a drill rod, wherein the shank is also provided with a rocker arm that moves relative to the shank, the rocker arm passing through the shank, and a linkage is provided between its front end and the drill rod.

[0005] As a further feature of the above solution, the crank handle also includes a central rod, a limiting part is provided at the front end of the central rod, a limiting groove is provided on the linkage component, the limiting part and the limiting groove are fitted together and fixed circumferentially, and bolt slots are also provided on the limiting part and the limiting groove.

[0006] As a further feature of the above scheme, the middle rod is provided with a groove, the groove is open relative to the end of the crank handle and is provided with a plug, and the axial length of the groove is greater than or equal to that of the drill rod.

[0007] As a further feature of the above solution, a crank handle is hinged to the crank arm, a two-section handle is hinged to the crank handle, and a storage groove is provided on the tool handle.

[0008] As a further feature of the above solution, the linkage component is provided with a fixing hole on the side opposite to the limiting groove for mounting with a flat-head set screw.

[0009] Beneficial effects: The shank-mounted drill bit of this utility model has a groove that allows the drill rod to be stored and carried when not in use, or a replacement rod to be installed inside for easy replacement as needed. In addition, the crank handle on the handle of this embodiment can be flipped and fitted into the storage groove when not in use. Furthermore, the two-section handle with secondary hinge allows the crank handle and the two-section handle to be flipped out during use, making it easier to drive the drill rod to rotate, which is convenient for drilling.

[0015] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0016] like Figure 1-4 The illustrated shank drill bit includes a shank 1 and a drill rod 2. The shank 1 is also provided with a rocker arm 3 that moves relative to the shank 1. The rocker arm 3 passes through the shank 1, and a linkage 4 is provided between its front end and the drill rod 2. The shank drill bit of this utility model can rotate the rocker arm 3 relative to the shank 1 by holding the shank 1 and rotating it, thereby driving the drill rod 2, which is circumferentially fixed thereto, to rotate, such as to drill a target or perform rotational machining operations.

[0017] As a further provision of the above scheme, the crank handle 3 also includes a central rod 34, a limiting part 35 is provided at the front end of the central rod 34, a limiting groove 36 is provided on the linkage 4, the limiting part 35 and the limiting groove 36 are fitted together and fixed circumferentially, and the limiting part 35 and the limiting groove 36 are also provided with bolt slots 37.

[0018] As a further feature of the above scheme, the middle rod 34 is provided with a groove 8, the groove 8 has an opening 38 at the end of the crank handle 3 and is provided with a plug 9, and the axial length of the groove 8 is greater than or equal to that of the drill rod 2.

[0019] As a further feature of the above scheme, a crank handle 31 is hinged to the crank handle 3, a two-section handle 32 is hinged to the crank handle 31, and a storage groove 33 is also provided on the tool handle 1.

[0020] As a further feature of the above scheme, the linkage 4 is provided with a fixing hole 22 for mounting the flat-head set screw on the side opposite to the limiting groove 36.

[0021] like Figure 1-4 As shown, the shank drill bit tool of this embodiment can be stored in the drill rod 2 when it is not in use by setting the groove 8, which makes it easy to carry, or a replacement rod can be set in it for convenient use. In addition, the crank handle 31 on the crank handle 3 of this embodiment is provided with a two-section handle 32 with secondary hinge. When in use, the two-section handle 32 makes it more convenient to perform drilling and other processing, and can drive the drill rod 2 to rotate more easily.

[0022] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
