A holder 6 is made of a synthetic turning and is fixed to the power supply unit 2 by a screw 34 of a side of the body 31 and a screw 34 of a screw hole 33 of the body 31. Support with 35 on. The shape of the engaging portion provided in the jaw arm 12 of the jaw body 5 can be used as long as it can be matched with the holder 6 so as to match the shape of the engaging portion. Can be changed in a variety of designs. For example, the % end of the Z-clamp #12 is set as the opening or the groove of the engaging portion (all of them can be replaced by the above-mentioned claw portion 15. The same reason, the retaining seat 6 f should be engaged, the needle on the forest 14, as long as the shape of the card & part of the jaw body can be changed, the design can be changed. The 3F table 7F is turned into the exploded perspective view of the tongs, and the 4th figure shows the longitudinal section of the jaw body. In this embodiment, the squeezing body 5 is formed by combining the two half-members 5a of the same shape. The half-member 200843236 has an inner surface shape of the outer shape of the plug 4, and has a plug # IU Μ川面面When the other side wall is assembled with the other side wall, the two half-side members 5a are held by the respective pieces of the card 42 to maintain the combined state.

The two side discriminating members 5a of the clip body are combined into a pliers (4), and assembled into a f. In this example, the jaws are clamped. The inner side of the side wall 11a of the 5 is formed to have a convex shape corresponding to the reduced diameter portion 4b of the plug 4, and the upper end of the wall 52 of the jaw body 5 is abutted against the reduced diameter portion 4b of the plug 4. Take the upper part of the fine position. Also, the rear part of the clamp body 5 is provided with the through hole 53 of the shaft surface 4 Wei's miscellaneous part 4σ boots wear ^ large = this constitutes '_4 is can be exposed to the county As for the connection between the Wei and the 11 sharp thieves, the movement of the sharp thief is far from the j-phase. It only means the action of the side clamp arm, and the movement of the other side of the citrus arm is the same, and it goes without saying. If the 1 clamp body 5 is fixedly attached to the holder 6, first, as shown in Fig. 5 (4), the user holds the jaws of the jaw body 5 with the fingers (usually the thumb and forefinger). When the front end of the clamp body 5 is opposed to the retaining seat 6 cylinder = forward push, the two protruding wall 22 can advance along the one side surface 21a of the retaining seat t Qi another wall 21 to guide the jaw body 5 toward the cylindrical portion 21. At the same time, the inclined surface 15b of the claw portion 15 first contacts the surface 1 of the claw portion 14, and as the forceps 5 continues to advance along the inclined surface Ub, the clamp arm 12 is forced to open outward as shown in Fig. 5. (6) shown Therefore, the clamp arm 200843236 12, that is, the hinge piece 13 as the support hinge piece 13 also undergoes elastic stepping: ^ rotation, the front end of which is thus outwardly stretched, and the deflection of the large curvature is in a state of curvature. The spring portion of the shape is also followed by the user from the S闰~, when the holder 6 is held, the claw portion 15 is inclined twice, and the state is further advanced while the jaw body 5 is pushed toward the clamp arm 12 at the same time. The inclined surface 14b of the portion 14 is rotated in the direction, and the front end back_side 3^ fulcrum is turned over the opposite side of the inclined surface 15b over the claw portion 14^6^"the claw portion 15 surface 15a and the claw portion 14 shown in Fig. 2 The engaging surface ^ and the engaging and retaining seat 6 of the claw portion 15 are combined into a body portion', and the second rebounding force of the jaw body 5 and the elastic deformation is added to the hinge portion 13 to achieve And the stability of the card relationship. κ °卩17's elasticity sets the original force'. According to this kind of locking structure, not only can the order & can improve the lock _ the durability of the _ the durability = ^ and the part 15 can be combined, so that the lock can be made $ "Kata" sound ^. , '疋κ refers to the connection of the t-seat 6 so that the grip portion 16 of the grip body 12 is pressed inwardly by the hand 5, so that the jaw end of the pliers april 2 is opened outward, and the jaw body 5 is simultaneously opened. Backward, that is, pulling away from the holder 6, OK. At this time, the engagement surface i5a of the claw portion 15 passes over the surface, and as shown in Fig. 5 (6), the oblique portion i4b is detached from the inclined surface i4b of the claw portion 14, and the engagement of the claw portion 15 is solved. The claw portion 15 is moved rearward with the jaw body 5, and the slope/face 14b of the inclined surface 15^ portion 14 slides rearward and returns to the disengaged state as shown in Fig. 5(4). The above is a detailed description of the specific embodiment of the present invention. It is to be noted that this job is only - can be implemented, and the present invention does not. In this embodiment, for example, in the present invention, if the elastic engagement piece having the same structure as the above-mentioned jaw 2 is directly provided at the end of the power cord (plug, socket, connector, etc.) It is feasible.
