Fix one end of the watchband spring, and lengthen the outer pipe1 of the watchband spring, to make the both ends stick in the watch cover tightly without any gaps. Wherein, one is the fixed head2. another is the movable head3, the spring4 is in the outer pipe, and in order to separate the spring and the tangential line, the tangential line is marked as 5. The usage of the watchband spring is: when load the watchband it is the same as before, but after the load it can't be taken away, we must break the opening of the movable head3 by using the 0.5mm drill.
