Compared with the traditional inclined sliding mode, the longitudinal key stroke of the key 200 can be reduced, the thickness of the telescopic structure is reduced, and the miniaturized development trend of the current intelligent bracelet and intelligent watch is adapted;

specifically, as shown in fig. 10, a structure of sliding on an inclined plane is adopted in the past, a required lateral movement distance of a telescopic rod is set as a, a key stroke of a cap body is set as b, and a distance of the inclined plane is set as c, when c is 1.7mm, the a can be unlocked successfully only when the a needs to be 1.4mm, and at this time, the key stroke of the cap body needs to be 1.0mm to meet the length requirement of the a; by adopting the arc guide mechanism 600, as shown in fig. 11, the required transverse movement distance of the telescopic rod is set as a1, the key stroke of the cap body is set as b1, the distance between the circle centers of the two ends of the arc is set as c1, when c1 is 1.7mm and a1 is 1.4mm, b1 can meet the requirement of a1 only by a key stroke of 0.9mm, and the required longitudinal space is shortened; further, at this time, the diameter d1 of the two ends of the circular arc through groove 621 is 0.8mm, the diameter d2 of the outer arc is 3.9mm, and the diameter d3 of the inner arc is 2.3mm. The data can be adaptively adjusted according to the required transverse moving distance of the telescopic rod.

In addition, compared with the conventional inclined sliding mode, the mode that the arc through groove 621 slides relatively can bring smoother hand feeling, and because the inclined sliding mode is in mutual contact in a surface-to-surface mode, the contact surface is large, the generated friction force is relatively large, and the abrasion can occur after the inclined sliding mode is used for a long time, so that the tolerance is caused, and the matching precision is influenced; and this circular arc leads to groove 621 through carrying out sliding connection with guide post 610, compares in current inclined plane cooperation, has that the contact surface is littleer, advantage that frictional force is littleer, promotes and feels, increase of service life.

The working principle is as follows: as shown in fig. 12-17, in the default state, the first elastic element 300 and the second elastic element 500 are in the resilient state, the button 200 is at the highest point of travel, the rod 400 extends outward from the sliding through hole 113 to be connected with the watch band for locking, and the guide post 610 is at the upper end travel of the circular arc through groove 621 at this time. When the key 200 is pressed downwards, the first elastic element 300 is compressed, the guide post 610 moves downwards along with the key 200, at this time, the circular arc through groove 621 generates relative sliding, the rod body 400 is driven to retract towards the shell 100, and the second elastic element 500 is compressed, after the key 200 is completely pressed, the guide post 610 is located at the lower end stroke of the circular arc through groove 621, the rod body 400 retracts into the shell 100 completely, and the unlocking of the watch band is realized. When the watch needs to be locked again, the key 200 is only needed to be released, and at this time, the first elastic element 300 and the second elastic element 500 rebound, so that the rod body 400 is driven to extend outwards to the sliding through hole 113 to be connected with the watch band to realize locking.
