The convex part has an opened groove and the concave part has a pivotal rod corresponding to the opened groove and pivotally arranged into the opened groove. Therefore, the first lever can be vertically assembled to the second lever. The second lever has two clamping parts on two lateral sides thereof and clamping the pivotal stages of the base. Therefore, the first lever and the second lever are firmly retained on the base and stably guide the keytop such that the keytop will not be shaken during operation.
