Technical Field

[0001] The utility model relates to a combined double-head drilling tool. Background Art

[0002] In modern manufacturing and mechanical engineering, drilling is a common process. To meet different work requirements, engineers have designed a variety of drilling tools. However, as the diversity and complexity of the work increases, the performance requirements for the tools are also getting higher and higher.

[0003] In order to adapt to changing working conditions and improve work efficiency, double-ended drilling tool designs have appeared on the market. The design of double-ended drilling tools can provide two different sizes or types of drilling functions to a certain extent, but they are usually fixed on one axis and cannot be easily adjusted or replaced. Utility Model Content

[0004] The main purpose of the utility model is to provide a combined double-ended drilling tool to solve the problems raised in the above background technology.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] A combined double-ended drilling tool comprises a first drill tip and a second drill tip arranged opposite to each other, wherein a first connecting block is arranged at the bottom of the first drill tip, a second connecting block is arranged at the bottom of the second drill tip, a first thread is arranged at the outer side of the first connecting block, a second thread is arranged at the outer side of the second connecting block, and an internally threaded connecting tube is arranged at the outer sides of the first connecting block and the second connecting block.

[0007] Preferably, a slide rail is provided at the bottom of the first connection block, and a slider used in conjunction with the slide rail is provided at the bottom of the second connection block.

[0008] Preferably, one side of the slide rail is closed, and the other side of the slide rail passes through the side wall of the first connecting block.

[0009] Preferably, third threads are provided at both ends of the outer wall of the internally threaded connecting pipe.

[0010] Preferably, the third thread and the first thread have opposite rotation directions.

[0011] Preferably, a reinforcement cap is provided above the internally threaded connecting pipe, and a fourth thread is provided inside the reinforcement cap.

[0012] Preferably, the reinforcement cap is provided with a through hole for the first drill tip and the second drill tip to pass through.

[0013] Beneficial technical effects of the utility model:

[0014] The separable first drill tip and second drill tip provided by the utility model improve the adaptability of the tool and allow the user to quickly replace the drill tip according to different work requirements. At the same time, the first connection block and the second connection block are connected and fixed by the internal threaded connection pipe, which ensures the stability of the connection and reduces the risk of loosening or falling off during work. The design of the slide rail and the slider ensures that the first drill tip and the second drill tip can be aligned when combined, so that the internal threaded connection pipe can easily connect the two. In addition, by connecting the reinforcement cap to the end of the internal threaded connection pipe, automatic loosening due to vibration or rotation is effectively prevented, which increases the safety and reliability in use.

DETAILED DESCRIPTION

[0020] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0021] like Figure 1-Figure 4As shown, the combined double-ended drilling tool provided in this embodiment includes a first drill tip 1 and a second drill tip 2 arranged opposite to each other, a first connecting block 3 is arranged at the bottom of the first drill tip 1, a second connecting block 4 is arranged at the bottom of the second drill tip 2, a first thread 5 is arranged on the outer side of the first connecting block 3, a second thread 6 is arranged on the outer side of the second connecting block 4, and an internal thread connecting tube 7 is arranged on the outer side of the first connecting block 3 and the second connecting block 4. When in use, the positions of the first drill tip 1 and the second drill tip 2 are adjusted so that the two are arranged opposite to each other and the bottom surfaces of the first connecting block 3 and the second connecting block 4 overlap. When the first drill tip 1 needs to be used for drilling a hole, one end of the internal thread connecting tube 7 is overlapped with the top surface of the first connecting block 3, and the rest of the internal thread connecting tube 7 wraps the second drill tip 2 to serve as a drill handle, and vice versa.

[0022] In this embodiment, if Figure 1 As shown, a slide rail 8 is provided at the bottom of the first connecting block 3, and a slider 9 used in conjunction with the slide rail 8 is provided at the bottom of the second connecting block 4. One side of the slide rail 8 is closed, and the other side of the slide rail 8 passes through the side wall of the first connecting block 3, ensuring that the first drill tip 1 and the second drill tip 2 can be accurately aligned when combined, simplifying the assembly process and improving the overall structural stability.

[0023] In this embodiment, if Figure 1 As shown, third threads 10 are provided at both ends of the outer wall of the internal threaded connecting tube 7, a reinforcement cap 11 is provided above the internal threaded connecting tube 7, and a fourth thread 12 is provided on the inner side of the reinforcement cap 11. The rotation directions of the third thread 10 and the first thread 5 are opposite, which helps to prevent automatic loosening under the action of vibration or rotational torque, thereby improving safety and reliability during use.

[0024] In this embodiment, if Figure 1 As shown, the reinforcing cap 11 is provided with a through hole 13 for the first drill tip 1 and the second drill tip 2 to pass through, so as to facilitate installation.

[0025] In summary, in this embodiment, the separable first drill tip 1 and second drill tip 2 provided in this embodiment improve the adaptability of the tool, allowing the user to quickly replace the drill tip according to different work requirements. At the same time, the first connecting block 3 and the second connecting block 4 are connected and fixed by the internal threaded connecting tube 7, which ensures the stability of the connection and reduces the risk of loosening or falling off during work. The design of the slide rail 8 and the slider 9 ensures that the first drill tip 1 and the second drill tip 2 can be aligned when combined, so that the internal threaded connecting tube 7 can easily connect the two. In addition, by connecting the reinforcement cap 11 to the end of the internal threaded connecting tube 7, automatic loosening due to vibration or rotation is effectively prevented, thereby increasing safety and reliability during use.

[0026] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
