Description

Technical Field

[0001] This utility model relates to the field of hole opener positioning aids, specifically a hole opener positioning aid. Background Technology

[0002] A hole saw, mounted on a regular electric drill, allows for easy cutting of round, square, and triangular holes, as well as straight and curved lines, on flat or spherical surfaces of various materials such as copper, iron, stainless steel, and plexiglass. It is flexible, convenient, safe, and widely applicable. Classified by material, hole saws include bimetallic, carbide, and diamond hole saws. Different materials are used for different cutting methods. Bimetallic hole saws are the most commonly used, while carbide hole saws are recommended for harder metals, and diamond hole saws are recommended for fragile materials such as glass, carbon fiber, and ceramics.

[0003] The existing connection methods between the support shank and the drill bit and hole saw are mostly threaded connections. After long-term use, the threads will strip, making it inconvenient to remove the drill bit and hole saw from the support shank. This results in low hole-making efficiency, poor practicality, difficulty in ensuring the hole-making accuracy of the workpiece, and inconvenient assembly. Utility Model Content

[0004] The purpose of this utility model is to provide a hole opener positioning aid to solve the problems mentioned in the background art, which has the advantage of convenient assembly.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hole opener positioning aid, comprising a connecting post, the side of which is configured as a hexagonal prism, a connecting ring sleeved on the connecting post, a first inwardly recessed annular groove at one end of the connecting post, a first retaining spring being engaged with the connecting post through the first annular groove, a limiting member at the other end of the connecting post, a spring being provided between the limiting member and the connecting ring, multiple retaining rods being fixedly connected to the connecting ring, a connecting rod integrally connected to one end of the connecting post, and a threaded block integrally connected to the other end of the connecting post.

[0006] By adopting the above technical solution, pressing the connecting ring causes it to move towards the limiting component. At this time, the locking rod will not contact the hole opener, and the spring will be compressed to apply force to the connecting ring, thus achieving the purpose of threaded connection between the threaded block and the external hole opener. After the threaded block and the hole opener are threadedly connected, the connecting ring is released, and under the action of the spring, the locking rod is inserted into the slot to play a limiting role. The limiting component plays a limiting role on the spring, and the first retaining spring can limit the connecting ring at one end of the connecting post.

[0007] As a further embodiment of this utility model: the limiting member includes an inwardly recessed second annular groove provided at the other end of the connecting post, the connecting post is engaged with a second retaining spring through the second annular groove, and the spring is disposed between the second retaining spring and the connecting ring.

[0008] By adopting the above technical solution, the second snap ring, together with the connecting ring, plays a limiting role for the spring.

[0009] As a further embodiment of this utility model: the limiting member includes a limiting ring integrally connected to the other end of the connecting column, the spring is disposed between the limiting ring and the connecting ring, and a limiting protective sleeve is provided on the outer side of the connecting column.

[0010] By adopting the above technical solution, the limiting ring and the connecting ring together play a limiting role for the spring.

[0011] As a further improvement of this utility model, a limiting protective sleeve is provided on the outer side of the connecting column.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] Press the connecting ring to move it toward the limiting component. At this time, the locking rod will not contact the hole opener, and the spring will be compressed to apply force to the connecting ring, so as to achieve the purpose of threaded connection between the threaded block and the hole opener. After the threaded block and the hole opener are threadedly connected, release the connecting ring. Under the action of the spring, the locking rod will be inserted into the slot to play a secondary fixing role. The limiting component plays a limiting role on the spring. The first retaining spring can limit the connecting ring at one end of the connecting post. Attached Figure Description

[0021] The technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0022] In this embodiment of the utility model,

[0023] A hole punch positioning aid, such as Figures 1-6 As shown, it includes a connecting post 1, the side of which is set as a hexagonal prism. A connecting ring 3 is sleeved on the connecting post 1. One end of the connecting post 1 is provided with an inwardly recessed first annular groove 4. The connecting post 1 is engaged with a first retaining spring 5 through the first annular groove 4. A limiting member is provided at the other end of the connecting post 1. A spring 6 is provided between the limiting member and the connecting ring 3. Multiple retaining rods 7 are fixedly connected to the connecting ring 3. A connecting rod 8 is integrally connected to one end of the connecting post 1. A threaded block 9 is integrally connected to the other end of the connecting post 1.
