Abstract: The press-connecting pliers mainly comprises a main body, a testing unit and an electric power supplying unit; the main body at least has a press-connecting slot for press connecting of an electric communication terminal and a transmitting line; the testing unit is provided in the main body and comprises an electric circuit board, a testing insertion groove and an indicating unit for the purpose of examining whether the communication terminal is electrically connected after press connecting, and using the electric power supplying unit to supply electric power required by the testing unit. Thereby, after press connecting of the electric communication terminal using the press-connecting slot, it is convenient to examine whether the communication terminal is electrically connected after press connecting directly through the testing unit.

Abstract: A folding wheelchair includes two side frame units arranged in parallel at two sides, each side frame unit formed of two four-bar linkages arranged at different elevations, a plurality of folding bars transversely coupled between the side frame units, two sets of guide rods respectively coupled to the side frame units and adapted to guide folding of the wheelchair between the extended position and the collapsed position, and two swivel hooks for hooking on the pivot between each set of guide rods to lock the wheelchair in the extended position.

Abstract: The pair of press-connecting pliers mainly have a first handle provided with a press-connecting die block, the press-connecting die block at least has two set of press-connecting sections allowing diversion and position changing, while the second handle can drive a press-connecting head to move toward the press-connecting die block to press connect a set of wire and pin in cooperation with the two set of press-connecting sections capable of being opposite to the press-connecting head after diversion; and by the functions of diversion and position changing of the two set of press-connecting sections, the press-connecting pliers at least can do press connecting of pins and wires of two specifications.

Abstract: The pair of press-connecting pliers for pins on electric communication terminals are provided on the front and rear sides of thereof with three kinds of press-connecting grooves. One of the two sides is formed thereon a first press-connecting groove and a second press-connecting groove, while the other side is formed thereon a third press-connecting groove in opposition to the second press-connecting groove; so that the left and right sides of the press-connecting pliers are formed thereon two terminal holding seats respectively from the first press-connecting groove, the second press-connecting groove and the third press-connecting groove, thereby the two terminal holding seats at least can simultaneously do press connecting for pins on electric communication wires and electric communication terminals of three different types, this simplifies the size of the entire press-connecting pliers.

Abstract: A pair of multifunctional peeling pliers of which a pair of mutually confronting cutting blades are provided on the handles of the pliers, the pliers are provided with a plurality of peeling knives and wire receiving recesses having suitable spaces respectively from the cutting blades of the handles; and a spring is provided between the handles of the pliers. Thereby, the whole pliers can be used to cut wires by means of the cutting blades and to practice peeling of a coating layer of a wire taking advantage of the section on one of the handles having the peeling knives and wire receiving recesses. And when the pliers are not in use, the handles of the pliers can be in the closing state normally by the action of the spring to avoid exposure of blades of the cutting knife and the peeling knives and to increase safety of the entire pliers.

Abstract: A plastic handle structure of a clamp tool, wherein, a hard plastic layer is provided on the two lateral edge areas of the bottom plate thereof with two lateral edge portions for a fitting-over portion, and the opening of the fitting-over portion per se is provided with two lateral edge portions, the top of the hard plastic layer is cut to open. A transversely directed die block for shaping the fitting-over portion fills soft plastic material in the lateral edge portions for the fitting-over portion, the lateral edge portions of the fitting-over opening and the top cut portion during a soft plastic layer enveloping process, enveloping and filling processes of the soft plastic layer are thus completed, and the structure of the fitting-over portion can be shaped. In the entire operation for the plastic handle, the hard plastic layer can be molded from an upper and a lower die in order to reduce the waiting time to do the enveloping process of the soft plastic layer.

Abstract: A pair of rotational peeling pliers. The pliers include an upper and lower half part and an adjustment member, wherein, the middle sections of the upper and lower half parts are connected to form an upper and a lower clamping arm on the front section as well as an upper and lower handle on the rear section of the pliers. The upper clamping arm has a knife, and the lower clamping arm has wire recesses. When one of the recesses is filled by a wire, and the upper and lower clamping arms are pressed to get close to each other, the knife cuts into an outer insulation layer on the wire to peel it. The adjustment member includes a fixing seat, the knife and an adjustment portion. The fixing seat is inserted in the receiving groove with the bottom thereof fixedly clamping the knife.

Abstract: A terminal coupling pliers comprises a guiding block, a primary molding portion, and a secondary molding portion on the front side of a primary hand-grip, and cone-shaped grooves on the adjacent surface of the primary molding portion and the secondary molding portion, a secondary hand-grip pivoted on the central portion of the primary hand-grip, and a pushing block pivoted on the front side of the secondary hand-grip and being arranged within the guiding block wherein the pushing block having a terminal insertion hole on front side thereof. The pushing block can move toward the cone-shaped grooves as the primary and secondary hand-grips are pushed closely. During its application, the junction of the terminal coupled with the signal line is enclosed with a ring and inserted into the terminal insertion hole. By closing the primary hand-grip and the secondary hand-grip, the ring will be pushed, deformatively by the pushing block, against the molding hole to lock the terminal and the signal line firmly.

Abstract: A pair of pliers for connecting an end connector by compression, wherein, a main handle is provided on the front end thereof with a mould block which is provided on the front end thereof with an alignment notch, a clamping seat is provided behind the notch and is clamped by an elastic element, a secondary handle is pivotally connected in the middle of the main handle, a pusher block is pivotally connected to the secondary handle and is provided on a front end thereof with an end-connector socket, after closing by pressing of the main handle to the secondary handle, the pusher block pushes the end connector to compress a tapered pipe; after combination of the end connector with a signal line by insertion, the signal line is placed in the clamping seat, and the end connector is inserted in the socket, when the main handle and the secondary handle are closed by pressing to each other, a collar can be abutted on the inner side of the clamping seat, so that the end connector and the collar can be compressed to tig
