The setting of the water trough can smoothly discharge the debris. The annular diamond drill bit will wear during the drilling and cutting process.

[0003] According to a patent document with the existing publication number CN213234958U, an annular diamond drill bit is disclosed, which includes a working layer, the working layer includes a working layer end face, the working layer end face is used to drill and cut the object to be cut; the working layer end face is provided with a working layer water groove penetrating the inner and outer surfaces of the annular diamond drill bit, the working layer water groove is used to play a chip removal role when the annular diamond drill bit is advanced, and the working layer water groove is an inclined groove arranged with respect to the axial direction of the annular diamond drill bit; the annular diamond drill bit also includes a transition layer, and the transition layer is used to It is connected to the drill bit base to fix the annular diamond drill bit on the drill bit base. When this technical solution is in use, the transition layer water groove and the working layer water groove are staggered with each other, so that the transition layer water groove and the working layer water groove can occupy the circumferential length of the annular diamond drill bit as much as possible, thereby further increasing the circumferential groove length of the annular diamond drill bit, which is more convenient for the smooth chip removal of the annular diamond drill bit. Regarding the above technical solution, although this solution realizes smooth chip removal, it is impossible to limit the cutting depth during cutting, which is inconvenient when used.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] See also Figures 1 to 3 The utility model provides a technical solution: an annular diamond drill bit, comprising a drill bit body, the drill bit body comprising a fixed seat 1, a connecting seat 2 is fixed on the fixed seat 1, a supporting seat 3 is fixed on the top of the connecting seat 2, an annular groove is opened between the supporting seat 3 and the fixed seat 1, a drill bit 7 is fixed on the top of the supporting seat 3, a heat dissipation component 8 is opened between the drill bit 7 and the supporting seat 3, a fixing groove 4 and a supporting groove 5 are respectively opened on the supporting seat 3, the fixing groove 4 and the supporting groove 5 are staggered in the left and right distribution, the width of the supporting groove 5 is greater than the width of the fixing groove 4, and the inner walls of the supporting groove 5 and the fixing groove 4 are both provided with fixing holes 6, which facilitate the limited fixing of the limit block 9, and the inner walls of the fixing groove 4 and the supporting groove 5 support the two ends of the limit block 9 to avoid the influence caused by the swing of the limit block 9 during use.

[0020] In this embodiment, a limit block 9 is movably installed inside the support groove 5 and the fixed groove 4, and a mounting hole is opened on the limit block 9. A fixing mechanism 11 is rotatably installed inside the mounting hole, and one end of the fixing mechanism 11 is rotatably installed inside the fixing hole 6. The heat dissipation component 8 includes an opening 12, and the opening 12 is opened on the support seat 3 and the drill bit 7. An inclined hole 13 is opened at one end of the opening 12. The diameter of the inclined hole 13 is larger than the diameter of the opening 12. The diameter of the inclined hole 13 is larger than the diameter of the opening 12, so that the debris inside the opening 12 can be quickly thrown out from the inclined hole 13 at a later time.

[0021] When the device is in use, the fixing seat 1 is installed on the power equipment, and the annular groove between the connecting seat 2 and the supporting seat 3 provides the supporting seat 3 with limited fixing as a whole. When in use, the power mechanism drives the supporting seat 3 to rotate as a whole, and the rotation of the supporting seat 3 realizes friction drilling of the object through the drill bit 7. While drilling, the opening 12 and the inclined hole 13 cooperate to quickly remove the high temperature on the drill hole 7. The high temperature on the drill bit 7 at another position is quickly removed through the fixing groove 4 and the supporting groove 5. With the friction of the drill bit 7, the cutting and drilling of the object is completed. Before use, the limiting block 9 is installed in the fixing groove 4 or the supporting groove 5 according to the required drilling and cutting depth. After the limiting block 9 is installed in the supporting groove 5, the object can be cut to a high depth. After the limiting block 9 is installed in the fixing groove 4, the object can be cut to a shallow depth. During cutting, the supporting seat 3 drives the limiting block 9 to rotate. When the supporting seat 3 and the drill bit 7 are lowered, the object contacts the side of the limiting block 9. After the contact, the cutting depth can be quickly understood, thereby completing the stop of the drill bit 7, meeting the use in different situations.
