[0005] In order to achieve the above object, the utility model discloses the following technical scheme: a kind of easy-to-wear pearl flat bottom drill pearl of the utility model, including drill body part and drill bottom part, the drill body part is fixedly arranged on drill bottom part, the drill body part is circular truncated cone, the side surface of drill body part is cut into multiple continuous bevels of equal division, the drill bottom part is cylindrical, drill body part and drill bottom part are equipped with through pearl hole, the opening edge of the pearl hole in drill bottom part is equipped with internal chamfer.The flat bottom drill pearl of the utility model includes the drill body part of circular truncated cone and the drill bottom part of cylindrical, this structure design not only makes the utility model have the shape of diamond, but also can keep drill body part on top, drill bottom part in the state of falling down accurately and being worn on guide pearl strip (guide pearl rod) when arranging drill, arrange pearl smoothly and can guarantee the correctness of pearl position;In addition, this structure design can increase the stability of the utility model, can keep stable when pearl embroidering and not easy to incline, so that embroidery needle can be accurately worn in pearl hole and not easy to collide;The opening edge of the pearl hole in drill bottom part is equipped with internal chamfer, internal chamfer plays the role of guiding, so that the flat bottom drill pearl of the utility model is more easily worn on guide pearl strip (guide pearl rod), which is conducive to improving production efficiency.

[0006] Preferably, the drill body part and the drill bottom part are of homogeneous integral structure. The drill body part and the drill bottom part are of homogeneous integral structure, which is firm in structure and can be obtained by one-piece molding, thus facilitating processing.

[0007] Preferably, the drill body part and the drill bottom part are non-transparent, semi-transparent or transparent.

[0008] Preferably, the height of the drill body part is 1.3 to 1.5 times the height of the drill bottom part.

[0009] Preferably, the internal chamfer is bevel or round.

[0010] Preferably, the internal chamfer is round.

[0011] Preferably, the center line of the pearl hole is collinear with the center lines of the drill body part and the drill bottom part.

[0012] Therefore, the utility model has the following beneficial effects:

[0013] (1) The flat bottom drill pearl includes the drill body part of circular truncated cone and the drill bottom part of cylindrical, which has the shape of diamond, and can be worn on guide pearl strip (guide pearl rod) when arranging drill, arrange pearl smoothly and can guarantee the accuracy of pearl position.
