Abstract: A connection structure is configured to connect a watchband including a watchband body to a watchcase including a watchcase body. The connection structure includes a latching member attached to a first end of the watchband body; and an elastic piece attached to the watchcase body and located in a locking slot of the watchcase body. When the latching member is inserted into the locking slot, the latching member is engaged with the elastic piece to thereby engage the watchband body with the watchcase body.
