[Brief explanation of drawings]

Fig. 1 is a perspective view of an embodiment of the present invention, Fig. 2 is an exploded view of the first upper jaw, Fig. 3 is a local sectional view of the operation of the adjustment device for the first upper jaw, and Fig. 4 is a peeled lower jaw. 5 is an exploded view of the tension member, FIG. 6 is a side view of the movable handle, and FIG. 7 is a detailed side view of FIG. 1. Amendment November 21, 1980 The claims for utility model registration and the brief description of the drawings are amended as follows. O Utility Model Registration Claims (1) A fixed gripping part is integrally attached, and a frame body is provided with a narrow guide window located toward the tip of the fixed gripping part, and fixed to the tip of this frame body. a first upper jaw member; a first upper jaw member whose one end is pivotally supported on a frame body so as to be rotatable with respect to the first upper jaw member, and whose free end forms a first bite opening; a lower jaw member; a movable gripping portion having a first shearing blade and having one end pivotally supported on the frame body so as to be rotatable with respect to the fixed gripping portion; a second shearing blade that is pivotally supported; a first pin that is inserted through the first lower jaw member, the second shearing blade, and the movable grip and pivotally supported so that they can move within a narrow window of the frame body; a second pin for pivotally supporting one end of the first lower jaw member and a second shearing blade at a position slightly above the first pin of the frame; and a second pin that contacts the lower jaw member and fixedly grips the movable gripping portion. pushing the first lower jaw member so that when the first lower jaw member is rotated toward the lower jaw member, the first lower jaw member is rotated toward the first upper jaw member; a pair of tension members which can form an occlusal opening with their distal ends thereof, and a first tension member between the first upper jaw member and the first lower jaw member which is biased by a spring into a normally open state; a peeling blade located behind the biting mouth and having its rear end engaged with the distal end of the movable gripping part so as to be able to advance and retreat; and a second upper jaw member integrally formed with the movable gripping part. , a second lower jaw member integrally formed with the second shearing blade to form a second bite opening that is rotatable in conjunction with the second upper jaw member, and a movable grip with respect to the fixed grip part; By rotating the part,
Bit the coated conductor wire with the first biting hole, cut the coating at the tip part with the biting hole, and simultaneously pull it out.
, a multi-purpose pliers that allows the second shearing blade to face the conductor and the second gripping opening to overlap and crimp the conductor terminals. (2) The tension member has one end attached to the movable gripping part. The pivotally supported rotary member, the abutting member provided at the other end, and the rotatable member are urged to rotate by their elasticity so that the corresponding abutting member abuts the first lower jaw member and is fixedly gripped. and a tension spring capable of pushing the first lower jaw member when the movable gripping part is rotated relative to the first lower jaw member. (3) The first jaw member is provided with a downwardly opening recess, and the recess has a built-in adjustment device for adjusting the size of the skinning blade. Multi-purpose pliers as described in section. (4) The multi-purpose pliers according to claim 3, wherein the adjustment device comprises an adjustment member that presses the skinning blade against it, and an adjustment operation member that can finely adjust the pressure of the adjustment member.

FIG. 7 is a detailed side view of FIG. 1.

Claims (4)

[Scope of utility model registration request] (1) A frame body to which a fixed handle is integrally attached and a narrow guide window positioned toward the distal end of the fixed handle; a first upper jaw member fixed to the distal end of the frame; a first lower jaw member whose one end is pivoted to the frame body so as to be rotatable relative to the first upper jaw member, and whose free end forms a first bite opening; a movable handle having a shearing knife and having one end pivoted to the frame so as to be rotatable with respect to the fixed handle; a second shearing blade having one end pivoted to the frame so as to be rotatable with respect to the first shearing blade; , a first pin for inserting the first lower jaw member, the second shearing blade, and the movable handle and pivotally fixing them to a narrow window of the frame for limited movement; and one end portion of the first lower jaw member. and a second pin for pivotally fixing a second shearing blade to a position slightly above the first pin on the frame; a tensioning member capable of pushing the first lower jaw member so as to rotate toward the jaw member; a skinning blade located behind the first biting opening between the upper jaw member and the first lower jaw member and having its rear end engaged with a movable handle tip and interlocked so as to be able to move forward and backward; a second upper jaw member integrally formed with the handle; and a second lower jaw member integrally formed with the second shearing blade so as to form a second bite opening that is rotatable in contact with the second upper jaw member. By rotating the movable handle with respect to the fixed handle, the covered conductor is bitten by the first biting opening, and the coating at the tip thereof is cut by the biting opening and handled at the same time. Multi-purpose pliers capable of shearing conductive wires with the second shearing blades and also capable of stacking and bonding conductive wire terminals with each other through the second gripping openings. (2) The tension member includes a rotating member whose one end is pivotally fixed to the movable handle, an abutting member provided at the other end, and a corresponding abutting member that is biased to rotate by the elasticity of the rotating member. is the first above
2. The pliers according to claim 1, further comprising a tension spring that is in contact with the lower jaw member and can push the first lower jaw member when the rotating handle is rotated relative to the fixed handle. (3) The pliers according to item 1 above, wherein the first jaw member is provided with a recess that opens downward, and the recess has a built-in adjustment device for adjusting the size of the peeling blade. .
