The connecting portion is extended along a reference axis and has a connecting end disposed at a bottom end thereof along the reference axis. The pressing portion has a front edge and a rear edge along a radial direction of the reference axis. A top edge of the pressing portion opposite to the connecting portion is provided with a pressing surface. A first length is defined from a proximal end of the pressing surface adjacent to the front edge to the connecting end along the reference axis. A second length is defined from a distal end of the pressing surface adjacent to the rear edge to the connecting end along the reference axis. The first length and the second length are not equal.
