If there is a description of "first" or "second", it is only used for the purpose of distinguishing the technical features, and cannot be understood as indicating or implying the relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0030] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0031] See also Figure 1-8 The utility model provides a technical solution: a diamond drill bit that is easy to install, comprising a rotating rod 3, four limiting grooves 6 are opened on the surface of the rotating rod 3, and a double drill bit mounting device is arranged on the surface of the rotating rod 3;

[0032] The double drill bit installation device includes two drill bits 5, and the surfaces of the two drill bits 5 are fixedly connected to the surface of the rotating rod 3;

[0033] Among them, the limiting strips 2 are arranged inside the four limiting grooves 6;

[0034] Among them, two positioning holes 7 are provided on the surfaces of the four limiting grooves 6;

[0035] The surfaces of the four limit strips 2 are each provided with two sliding holes 9 , the interiors of the eight sliding holes 9 are all slidably connected with positioning posts 10 , and the surfaces of the eight positioning posts 10 are in contact with the interiors of the corresponding positioning holes 7 .

[0036] The upper surfaces of the four limiting bars 2 are fixedly connected with the mounting components 1 , and the lower surfaces of the mounting components 1 are in contact with the surfaces of the corresponding drill bits 5 .

[0037] Two sliding grooves 11 are respectively formed on the surfaces of the four limiting bars 2 , and two springs 12 are fixedly connected to the surfaces of the eight sliding grooves 11 .

[0038] The interiors of the eight sliding grooves 11 are all slidably connected with disassembly buttons 13 , the surfaces of the eight disassembly buttons 13 are all fixedly connected to the surfaces of the corresponding positioning columns 10 , and the surfaces of the eight disassembly buttons 13 are all fixedly connected to the other ends of the corresponding springs 12 .

[0039] Two threaded holes 14 are respectively formed on the surface of the four limit bars 2 , and screws 4 are threadedly connected inside the eight threaded holes 14 .

[0040] Eight thread grooves 8 are formed inside the rotating rod 3 , and the interiors of the eight thread grooves 8 are all threadedly connected to the surfaces of the corresponding screws 4 .

[0041] When the drill bit 5 needs to be replaced, first, multiple screws 4 are rotated by a tool to remove the multiple screws 4, and then multiple disassembly buttons 13 are pushed to move by external force. The movement of the multiple disassembly buttons 13 drives the corresponding positioning columns 10 to move to disengage from the corresponding positioning holes 7. The movement of the multiple disassembly buttons 13 drives the corresponding springs 12 to be compressed, and then the external force is used to drive the rotating rod 3 to move. The movement of the rotating rod 3 drives the inside of the four limit grooves 6 to disengage from the surface of the corresponding limit strip 2.

[0042] Secondly, the rotating rod 3 is rotated by an external force, and the rotation of the rotating rod 3 drives the drill bit 5 to rotate.

[0043] Finally, the rotating rod 3 is driven to move by external force, and the movement of the rotating rod 3 drives the four limit slots 6 to move and contact the corresponding limit strips 2. When the multiple positioning holes 7 move to coincide with the positions of their corresponding positioning columns 10, the multiple disassembly buttons 13 are released, and the multiple springs 12 are reset to drive the corresponding disassembly buttons 13 to move. The movement of the multiple disassembly buttons 13 drives the corresponding positioning columns 10 to move into the corresponding positioning holes 7. When the sound of the multiple positioning columns 10 colliding with the inside of the positioning holes 7 is heard, the multiple screws 4 are installed by tools and enter the corresponding threaded grooves 8 and threaded holes 14.

[0044] By setting up the connection between multiple positioning columns 10 and their corresponding positioning holes 7 in the double drill bit installation device, the multiple positioning holes 7 are moved and collided with the inside of the corresponding positioning columns 10 under the elastic force of their springs 12, and make a sound. When the sound is heard, it proves that the positions of the multiple threaded holes 14 and their corresponding threaded grooves 8 coincide, and then the screws 4 can be installed. It can not only loosen the rotating rod 3 after hearing the sound, freeing both hands to take the multiple screws 4 and tools, but also make it easy for novices to judge whether they are aligned, thereby achieving the effect of easy installation.

[0045] By arranging two drill bits 5 to share a double drill bit installation device, the utilization rate of the double drill bit installation device is improved. Compared with the general one drill bit 5 corresponding to one rotating rod 3, two drill bits 5 sharing one rotating rod 3 can save more costs.

[0046] Working principle: When the drill bit 5 needs to be replaced, first, multiple screws 4 are rotated by a tool to remove the multiple screws 4, and then the multiple disassembly buttons 13 are pushed to move by external force. The movement of the multiple disassembly buttons 13 drives the corresponding positioning columns 10 to move to disengage from the corresponding positioning holes 7. The movement of the multiple disassembly buttons 13 drives the corresponding springs 12 to be compressed, and then the external force drives the rotating rod 3 to move. The movement of the rotating rod 3 drives the inside of the four limit grooves 6 to disengage from the surface of the corresponding limit strip 2.

[0047] Secondly, the rotating rod 3 is rotated by an external force, and the rotation of the rotating rod 3 drives the drill bit 5 to rotate.

[0048] Finally, the rotating rod 3 is driven to move by external force, and the movement of the rotating rod 3 drives the four limit slots 6 to move and contact the corresponding limit strips 2. When the multiple positioning holes 7 move to coincide with the positions of their corresponding positioning columns 10, the multiple disassembly buttons 13 are released, and the multiple springs 12 are reset to drive the corresponding disassembly buttons 13 to move. The movement of the multiple disassembly buttons 13 drives the corresponding positioning columns 10 to move into the corresponding positioning holes 7. When the sound of the multiple positioning columns 10 colliding with the inside of the positioning holes 7 is heard, the multiple screws 4 are installed by tools and enter the corresponding threaded grooves 8 and threaded holes 14.

[0049] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
