A deep hole drill bit is a drill bit used for drilling deeper holes. Existing deep hole drill bits need to be twisted to be disassembled. When twisting and installing and replacing, lack of experience may easily cause the drill bit to be installed tilted, causing safety accidents. Utility Model Content

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model proposes a deep hole drill bit that is easy to replace, which effectively solves the problem that the deep hole drill bits on the market currently need to be twisted to disassemble, and the lack of experience during twisting and installation and replacement may easily cause the drill bit to be installed tilted, resulting in safety accidents.

[0004] The technical solution adopted by the utility model is as follows: The utility model proposes a deep hole drill bit that is easy to replace, including a limit head, a fixed seat, a slot, a drill rod, a double cutting edge and a spiral chip groove. The fixed seat is fixed on the limit head, the slot is arranged on the fixed seat, the drill rod is fixed on the fixed seat, the double cutting edge is arranged on the drill rod, and the spiral chip groove is arranged on the drill rod.

[0005] Preferably, the fixing seat is arranged between the limiting head and the drill rod.

[0006] In order to better achieve the effect of quick installation, the card slot is arranged in a circular shape.

[0007] In order to achieve the purpose of fixing more quickly, the card slots are provided with two groups.

[0008] Furthermore, the limit head is arranged in a hexagonal shape.

[0009] The beneficial effects achieved by the utility model using the above structure are as follows: the scheme proposes a deep hole drill bit that is easy to replace, which is fixed by snapping through a slot and fixed by limiting a position through a limiting head, thus avoiding installation troubles. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 The utility model is a schematic diagram of the overall structure of a deep hole drill bit that is easy to replace.

[0011] Among them, 1. limit head, 2. fixed seat, 3. slot, 4. drill rod, 5. double cutting edge, 6. spiral chip groove.

[0012] The accompanying drawings are used to provide a further understanding of the present invention and constitute a part of the specification. They are used together with the embodiments of the present invention to explain the present invention and do not constitute a limitation to the present invention. DETAILED DESCRIPTION

[0013] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0014] like Figure 1 As shown, the utility model proposes a deep hole drill bit that is easy to replace, including a limit head 1, a fixed seat 2, a slot 3, a drill rod 4, a double cutting edge 5 and a spiral chip groove 6. The fixed seat 2 is fixedly arranged on the limit head 1, the slot 3 is arranged on the fixed seat 2, the drill rod 4 is fixedly arranged on the fixed seat 2, the double cutting edge 5 is arranged on the drill rod 4, and the spiral chip groove 6 is arranged on the drill rod 4.

[0015] like Figure 1 As shown, the fixing seat 2 is arranged between the limiting head 1 and the drill rod 4 .

[0016] like Figure 1 As shown, the card slot 3 is arranged in a circular shape.

[0017] like Figure 1 As shown, the card slots 3 are provided in two groups.

[0018] like Figure 1 As shown, the limit head 1 is arranged in a hexagonal shape.

[0019] When in use, the user uses this device to first insert the limit head 1 into the limit of the electric drill, and then slide the fixing seat 2 on the electric drill into the slot 3 to fix the limit head 1. When in use, use the double cutting edge 5 to drill holes, and the deep hole waste chips are discharged through the spiral chip groove 6 to avoid blockage. The above is the entire use process of the deep hole drill bit that is easy to replace.

[0020] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
