[0002] A composite drill tool is a drill that combines multiple functions. It can complete multiple processing tasks such as drilling and reaming in one operation. This tool is usually made of carbide or high-speed steel, which has high wear resistance and strength. The design of the composite drill enables it to efficiently process different materials, such as metal, plastic, wood, etc. The composite drill has the characteristics of versatility, high efficiency and high precision. It needs to choose the right coolant or lubricant when working to reduce friction and heat, and extend the tool life.

[0003] During actual use, the drill bit continuously adds coolant or water impact when drilling to reduce the drilling temperature. The water mixed with debris will splash to the surroundings as the drill bit rotates. The drill bit and the fixture will also be stained with dirty water. This kind of dirty water mixed with debris will form stubborn stains if not cleaned in time, which will be difficult to clean later. In addition, the dirty water mixed with debris will have a certain flushing effect on the drill bit, affecting the drilling accuracy of the drill bit and causing great losses. Utility Model Content

[0026] Reference Figure 1-6 The utility model provides a self-cleaning composite drill bit tool, comprising a fixed connection seat 2 fixed to the handle of a drill bit 1, a docking ring 3 is connected to the bottom of the fixed connection seat 2, a tension spring 4 is connected to the bottom of the docking ring 3, the other end of the tension spring 4 is connected to a rotating base 5, a cleaning kit 6 is connected to the bottom of the rotating base 5, and the cleaning kit 6 rotates at the bottom of the rotating base 5;

[0027] Specifically, the cleaning kit 6 includes a movable sleeve 61 , which is sleeved on the outside of the drill bit 1 , and is internally connected to a cleaning sleeve 62 , in which a cleaning sponge 63 is fixed, and the cleaning sponge 63 is wrapped around the outside of the drill bit 1 .

[0028] Reference Figure 4-5 A plurality of fixed seats 31 are provided on the top of the docking ring 3, and docking slots 21 are provided at the bottom of the fixed connecting seat 2 corresponding to the plurality of fixed seats 31. A fixing hole 22 is reserved in the middle of the fixed connecting seat 2, and the fixing hole 22 is fixed to the handle of the drill bit 1.

[0029] Specifically, a plurality of fixed holders 31 are evenly spaced, and a block 32 is provided on one side of the fixed holder 31 close to the drill bit 1 . The block 32 is correspondingly fixed in the docking slot 21 , and a side of the block 32 close to the docking slot 21 is set as an inclined surface.

[0030] In this embodiment, the fixed connection seat 2 is first mounted on the handle of the drill bit 1. The docking ring 3 is fixed to the bottom of the fixed connection seat 2 through the cooperation of the docking slot 21 and the fixed seat 31. One end of the tension spring 4 is fixed to the bottom of the docking ring 3, and the other end is fixed to the top of the rotating base 5. The cleaning kit 6 is connected to the bottom of the rotating base 5, wherein the rotating slot 51 and the rotating extension plate 64 cooperate to ensure that the cleaning kit can rotate relative to the rotating base 5.

[0031] Reference Figure 1-3 The tension spring 4 is fixed at the bottom of the docking ring 3 and is arranged outside the drill bit 1, that is, the inner diameter of the tension spring 4 should be at least larger than the outer diameter of the drill bit 1, and the other end of the tension spring 4 is fixed at the top of the rotating base 5.

[0032] Reference Figure 6 A rotating groove 51 is provided at the bottom of the rotating base 5 , and a rotating extension plate 64 is provided at the top of the movable sleeve 61 corresponding to the rotating groove 51 , and the rotating extension plate 64 is clamped in the rotating groove 51 .
