[0002] An excavator is a commonly used engineering machinery, mainly used for excavation and loading operations. The excavator bucket tooth group is generally composed of two parts: a bucket tooth and a tooth seat. The rear part of the bucket tooth has a cavity, and the head of the tooth seat has a protrusion that can be accommodated in the cavity of the bucket tooth. The bucket tooth cavity and the protrusion on the head of the tooth seat are firmly combined together through the tooth pin. When replacement is needed, generally only the bucket tooth part that is easily worn needs to be replaced.

[0003] According to the patent with announcement number CN218374163U, a bucket tooth assembly of an excavator is proposed. The bucket tooth assembly of the excavator is provided with a connecting mechanism and a locking mechanism between the bucket tooth seat and the bucket tooth head. When the bucket tooth of the excavator is damaged, it is convenient to separate the bucket tooth seat from the bucket tooth head, which is beneficial to replace the bucket tooth seat and the bucket tooth head separately and avoid replacing the bucket teeth as a whole. It can not only reduce costs but also save resources.

[0004] However, the bucket tooth assembly of the excavator fixes the bucket tooth head by positioning bolts, so that after the bucket is used for a long time, the positioning bolts are easy to loosen, thereby causing the bucket tooth head to fall off. Therefore, a safe and stable excavator bucket tooth is proposed to solve the above problem. Utility Model Content

[0007] Furthermore, the internal threads of the excavator bucket and the sleeve are installed with four fixing bolts, and the four fixing bolts are evenly distributed when viewed from top to bottom.

[0008] Furthermore, the bucket tooth seat and the bucket tooth head are each provided with five, and the five bucket tooth heads are respectively spaced apart from the four fixing bolts.

[0009] Furthermore, movable holes are provided inside the bucket tooth head and the bucket tooth seat, and the inner surface of the movable hole is slidably connected to the outer surface of the sleeve.

[0010] Furthermore, an expansion portion is fixedly installed on one side opposite to the two sleeves, and an expansion block is fixedly installed on one side opposite to the two threaded rods.

[0011] Furthermore, the front and rear side walls of the inner cavity of the bucket tooth seat are in a conical shape, and the expansion block is in a conical shape.

[0012] Furthermore, the right side wall of the inner cavity of the movable hole is a limiting groove, and a limiting strip is fixedly installed on the right side of the sleeve, and the outer surface of the limiting strip is embedded in the inner surface of the limiting groove.

[0013] Compared with the prior art, the technical solution of this application has the following beneficial effects:
