Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, as Figure 1-4 As shown, this utility model provides a straightening auger drill bit, including a collar 1, a first connecting post 2 inside the collar 1, a second connecting post 3 on the lower side of the first connecting post 2, a first stud 4 fixed at the top of the first connecting post 2, a connector 5 installed at the bottom of the second connecting post 3, a drill bit body 6 installed at the bottom of the connector 5, and a buffer structure 13 for buffering the drill bit body 6 between the first connecting post 2 and the second connecting post 3.

[0023] The overall effect of Embodiment 1 is that, through the setting of the first stud 4, the device can be connected to an external impactor to play a righting role. Through the setting of the buffer structure 13, when the drill body 6 hits a hard object, it can buffer and reduce shock, avoiding damage to the drill body 6 or the connection of the device, thus making it more practical.

[0024] Example 2, as Figure 1-4As shown, the buffer structure 13 includes a spring 1301 fixed between the first connecting post 2 and the second connecting post 3. A damper 1302 is installed inside the spring 1301 between the first connecting post 2 and the second connecting post 3. A first connecting plate 1303 is fixed to the bottom end of the first connecting post 2 outside the spring 1301. A second connecting plate 1304 is fixed to the top end of the second connecting post 3 outside the first connecting plate 1303. Limiting blocks 14 are fixed to both ends of the outer wall of the first connecting plate 1303. Limiting grooves 15 matching the limiting blocks 14 are opened at both ends of the inner wall of the second connecting plate 1304. Multiple connecting brackets 11 are fixed on the outer wall of the 2. The ends of the multiple connecting brackets 11 away from the first connecting post 2 are fixed to the inner wall of the collar 1. The outer walls of the first connecting post 2 and the second connecting post 3 located outside the collar 1 are both provided with a first wrench groove 12. The outer wall of the connector 5 is provided with a second wrench groove 16. The top of the connector 5 is fixed with a second stud 7. The bottom of the second connecting post 3 is provided with a threaded groove 8 that matches the second stud 7. The second stud 7 and the threaded groove 8 are threadedly connected. The inner wall of the collar 1 is fixed with a baffle 9. The second connecting post 3 passes through the baffle 9 and is slidably connected to the baffle 9. The outer wall of the drill bit body 6 is provided with a slot.

[0025] The overall effect of Embodiment 2 is that, through the setting of the second stud 7 and the screw groove 8, when it is necessary to replace the connector 5 and the drill body 6, it is only necessary to pull the second wrench groove 16 with a wrench to drive the connector 5 to rotate, thereby driving the connector 5 and the drill body 6 to be threaded out, which is convenient for replacement and more practical. In addition, the slot opened on the outer wall of the drill body 6 makes it drill faster, which is more practical. When the drill body 6 hits a hard object, it will drive the second connecting post 3 to move upward. Through the operation of the spring 1301 and the damper 1302, it will be buffered and shock-absorbing, avoiding damage to the drill body 6 or the connection of the device, which is more practical.

[0026] Working principle: When in use, the first stud 4 connects to an external impactor for straightening. With the second stud 7 and the threaded groove 8, when the connector 5 and drill body 6 need to be replaced, simply pull the wrench through the second wrench groove 16 to rotate the connector 5, thereby causing the connector 5 and drill body 6 to be threaded out for easy replacement. Furthermore, the slot on the outer wall of the drill body 6 allows for faster drilling. When the drill body 6 impacts a hard object, it causes the second connector 3 to move upwards. The operation of the spring 1301 and damper 1302 provides cushioning and shock absorption, preventing damage to the drill body 6 or the connection points of the device. Additionally, when drilling, simply rotating the device in the opposite direction to the rotation of the second stud 7 within the threaded groove 8 will prevent the second stud 7 from automatically rotating out.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
