An improved structure of bucket tooth for construction tools includes an adapter and a bucket tooth mounted on the adapter. The adapter has an accommodating room and a fixing section. Both side of the bucket tooth have a hole, respectively. An engaging unit is disposed at the accommodating room and the fixing section of the adapter and between the holes of the bucket tooth. The engaging unit includes a lock, an elastic element, and a fixing element. The end of the lock protruding from the accommodating room has an outer angle facing the fixing part to urge against the inner angle in the corresponding hole of the bucket tooth. The lock can thus position the bucket tooth on the adapter and maintains no impact gap between them. When the engaging unit loses its effect, the fixing element prevents the bucket tooth from falling off the adapter.
