Abstract: A pair of pliers for loading-unloading E-type clamping piece mainly comprises a clamping operational strip in shape of a long flat board, wherein a C-opening is formed at one end and a crotched opening at the other; and a handgrip that can be inserted with those two ends of the clamping operational strip alternatively. The handgrip is further provided with a movable pin, which can move up or down, fastening to the clamping operational strip. By virtue of abovesaid construction, the clamping operational strip can hold an E-type clamping piece to clamp at a circular groove on a target article, or vice versa. The C-opening can be used by the way to select a required E-type clamping piece by comparing its opening width with outer diameter of the circular groove on a target article.

Abstract: A retainer puller including a head with two clamp halves commonly having an opening at their front ends and a handle at their rear ends, and a bolt. The clamp halves are each provided with a hole. The bolt includes a polygonal head and a rod provided with an axial slot of a determined depth across the free end thereof. The rod of the bolt is rotatably secured through the respective holes of the clamp halves. In use, the free end of a retainer is inserted into the opening of the clamp halves and then into the slot of the bolt. By turning the bolt with a wrench, the free end of the retainer may be wound on the rod to reduce the internal diameter of the retainer and thus tighten the retainer on the objects onto which it is fastened.

Abstract: A tile cutting pliers including two horizontal cutting plates on two pivoted blades at one end and acted against each other to trim tiles, a first mounting frame and a second mounting frame respectively raised from either cutting plate, a circular cutter fastened to the first mounting frame at an outer side for cutting a scratch on tiles, and a jaw plate turned about a pivot on the second mounting frame, the jaw plate having a recessed portion on a front chucking face thereof transversely disposed in the middle, and wherein the jaw plate is turned inwards and moved to act against the first upright mounting frame to clamp a tile being placed therebetween or turned outwards from the first mounting frame for permitting the cutting plates to be acted against each other to cut a tile.

Abstract: A tile cutting tool including two opposing cutters integrally and respectively extended from two pivoted blades and disposed in reversed directions, two jaw plates respectively fastened to the cutters at one side, a cutting wheel fastened between the cutters and the jaw plates for making a scratch on the workpiece, the jaw plates including one having a concave middle part and the other having a convex middle part fitting over the concave middle part, whereby the jaw plates are worked against each other to break the workpiece along the scratch being made on the workpiece by the cutting wheel.

Abstract: A combination pliers including a first pliers body consisted of two pivoted blades with insulated grips, a second pliers body consisted of two pivoted blades attached to the pivot joint of the first pliers body, wherein the jaws of the first pliers body move apart from each other and the jaws of the second pliers body come together as the two insulated grips of the first pliers body are squeezed toward each other; the insulated grips of the first pliers body are returned to their former positions by a torsional spring as the inward pressure is released, causing the jaws of the first pliers body to come together and the jaws of the second pliers body to move apart from each other.
