ABSTRACT:
A clipper includes a first hollow tube that has an upper end provided with a first detachable trimming device and a lower end that is provided with a circumferential oblong slot that has an axial access which extends from the periphery of the lower end. The axial access includes two opposed faces, one of which has a projection formed thereon. The projection and a remaining one of the faces cooperatively define a predetermined clearance. A second hollow tube is inserted co-axially into the first tube and has an upper end provided with a second detachable trimming device, and a lower end that has an engaging rod which extends radially outward from an external surface of the second tube. The engaging rod has a diameter that is wider than the predetermined clearance. The engaging rod is pressed past the projection of the axial access of the first tube when the second tube is inserted into the first tube. Each of a pair of pressing plates has an upper portion attached pivotally to the upper end of the first tube and a lower end which is provided with a notch that engages the engaging rod of the second tube. A biasing spring biases lower portions of the pressing plates to move away from each other.
