The two cylinder chamber is in communication with an external power source. The connecting component includes a two-phase spaced connecting body and a joint portion, and the connecting portion detachably couples the two connecting bodies between the two caliper bodies. The two pistons are movably disposed in the two cylinder chambers, each of the pistons being drivable by the external power source.
