[0028] In this embodiment, the width direction of the bucket tooth 11 is the width direction of the bucket tooth sleeve 3. Figure 1-4The X-axis direction in the bucket is consistent; by setting a scraper 2 and setting a bucket tooth sleeve 3 on the scraper 2, the structure of the bucket tooth sleeve 3 corresponds to the structure of the bucket tooth 11 on the bucket 1, and the bucket tooth sleeve 3 can be sleeved on the bucket tooth 11 to connect the scraper 2 to the bucket 1. The bucket tooth sleeve 3 is a sleeve-shaped structure with an open end and a closed tip at the other end. The bucket tooth sleeve 3 can be sleeved on the bucket tooth 11 from the open side, and its tip corresponds to the tip of the bucket tooth 11. The bucket tooth sleeve 3 also includes a tip extending toward the bucket 1 and facing the Z direction. The bucket tooth sleeve 3 has four side walls in the positive and negative directions of the axis and the positive and negative directions of the X axis, and a first rotating plate 41 is provided in the inner cavity of the bucket tooth sleeve 3.

When the scraper 2 needs to be installed on the bucket 1, the bucket tooth sleeve 3 is sleeved on the bucket tooth 11. During this process, the tip of the bucket tooth 11 is inserted into the bucket tooth sleeve 3 along the gap between the first connecting block 43 and the lower wall of the inner cavity of the bucket tooth sleeve 3. The first spring 42 is squeezed by the extrusion force of the bucket tooth 11 and contracts. The first rotating plate 41 rotates in the direction away from the lower wall of the inner cavity of the bucket tooth sleeve 3 until the bucket tooth 11 moves to the first connecting groove 12 and is aligned with the first connecting block 43. The first connecting block 43 is embedded in the first connecting groove 12 under the elastic force of the first spring 42. The bucket tooth sleeve 3 is connected to the bucket tooth 11 through the connecting groove 12, thereby enabling the bucket tooth sleeve 3 to be engaged with the bucket tooth 11, that is, the scraper 2 is connected to the bucket 1. When the bucket 1 does not need the scraper 2, an external force is used to drive the first rotating plate 41 to rotate in a direction away from the lower wall of the inner cavity of the bucket tooth sleeve 3, so that the first connecting block 43 is disengaged from the first connecting groove 12, and the bucket tooth sleeve 3 is separated from the bucket tooth 11, thereby realizing the disassembly of the scraper 2.

Correspondingly, the first connecting groove 12 is also a wedge-shaped structure. In the process of separating the scraper 2 from the bucket 1, in order to pull the bucket tooth sleeve 3 away from the bucket tooth 11, an external force along the positive direction of the Y axis can be applied to the bucket tooth sleeve 3. At this time, the force on the inclined surface facilitates the separation of the first connecting block 43 from the first connecting groove 12, and the bucket tooth sleeve 3 is pulled away from the bucket tooth 11 without the use of additional tools.
