The watchband comprises at least one connecting assembly arranged in the length direction of thewatchband and a sensor; the sensor is arranged on one side, which is in contact with the limb of a user, of the watchband; the sensor is used for characteristic parameters of the user; the characteristic parameters are used for representing whether the length of the watchband is matched with the limb size of the user or not; the connecting assembly comprises a first connecting unit and at least one second connecting unit which are arranged in the length direction of the watchband; a coil is arranged in the first connecting unit; and magnetic poles are arranged in the second connecting unit. Under the interaction of magnetic poles generated after the coil in the first connecting unit is electrified and the magnetic poles arranged in the second connecting unit, the distance between the firstconnecting unit and the second connecting unit can be changed, so that the length of the watchband is matched with the limb size of the user.

Description

technical field [0001] The invention relates to the field of terminals, in particular to a strap, a watch and a method for controlling the length of the strap. Background technique [0002] In order to make it easy to wear and ensure that the length of the strap matches the thickness of the wrist, the strap is often designed as two parts that are fastened according to a certain fastening method (these two parts can be called A strap and B strap), for example , designed to press figure 1 The two parts snap together with the butterfly clasp shown, or designed to snap figure 2 The jacks shown snap together in two parts.
