[0012] As a preferred embodiment of the convenient locking structure for a watch strap according to this utility model, two guide rods are provided, and the two guide rods are symmetrically distributed on both sides of the bidirectional lead screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] By fitting the connecting frame at the end of the second watch strap onto the connecting seat, one end of the connecting frame will be embedded in the groove. Then, by rotating the rotating rod clockwise through the knob, the meshing relationship between the first and second bevel teeth will drive the bidirectional lead screw to rotate. At this time, the two threaded connecting blocks connected by the threads on the outer wall of the bidirectional lead screw will move in opposite directions along the guide rod, so that the limiting pin at the end of the connecting plate can extend outward and be inserted into the limiting slot on the outer wall of the connecting frame. This achieves convenient locking between the watch straps, and the structure is relatively simple. After locking, the watch strap is difficult to release unless manually operated, thus preventing the watch from getting lost. Attached Figure Description
