Detailed description of the invention

With reference to the accompanying drawings the utility model is described in further detail below.

As shown in Figure 1-Figure 3, the multifunctional pliers that the utility model embodiment relates to, comprise tong arm 1 and tong arm 23, described tong arm 1 and tong arm 23 are by the mutual cross-articulation of jointed shaft 15, one end of described jointed shaft 15 is fixed on tong arm 1, the other end of jointed shaft 15 is connected with screw rod 14, screw rod 14 is through described tong arm 23 and be rotary with nut 21, nut 21 radiuses are less than described jointed shaft 15 radiuses, on described screw rod 14, be connected with catch 20, catch 20 is between described tong arm 23 and nut 21 and rotatable being fixed on described tong arm 23, catch 20 radiuses are greater than described jointed shaft 15, the part that described screw rod 14 extends to described nut 21 outsides is provided with pin-and-hole, in pin-and-hole, cross-under has bearing pin 22, bearing pin 22 length are less than described jointed shaft 15 diameters, one side of described tong arm 1 and tong arm 23 is binding clip 2, binding clip 2 is circular arc, binding clip 2 inner sides are provided with tooth 1, binding clip 2 tops have pincers face 1, pincers face 1 has the tooth 2 10 of engagement, described binding clip 2 inner surfaces have the wrench faces vertical with pincers face 11 with pincers face 1 junction, described binding clip 2 is provided with Iron-shearing device blade 6 near the inner side, position of jointed shaft 15, Iron-shearing device blade 6 sides are wrench faces 2 13, the opposite side of described tong arm 1 and tong arm 23 is clamp handle 4, clamp handle 4 is provided with wire stripper 8 near the inner side, position of jointed shaft 15, on wire stripper 8, be distributed with in pairs multiple specifications different semicircle jaw 23, clamp handle 4 middle parts of described tong arm 23 are provided with spring 9, clamp handle 4 ends of described tong arm 1 and tong arm 23 have the hole of pulling 1, clamp handle 4 distal outer surface are provided with screw thread 16 and are connected with internal angle wrench 5 by described screw thread 16, internal angle wrench 5 tops have the hole of pulling 2 18, described tong arm 1 and tong arm 23 clamp handles 4 pull hole 1 and to pull hole 2 18 sizes different, 2 18 inner sides, the hole of pulling are provided with deep hole, dismountable being fixed with " one " font screwdriver 19 and " ten " font screwdriver 19 respectively in deep hole, screwdriver 19 terminal end shape are with to pull hole 2 18 identical, screwdriver 19 is connected in the deep hole of described internal angle wrench 5.

When concrete use, the pliers under assembled state can be used as pliers, mouth of pipe pincers, wire stripper 8 and iron shears, and the spring 9 at tong arm 23 places, for automatically strutting after clamp handle 4 is closed up, makes operation more laborsaving.Simultaneously, the clamp handle 4 of tong arm 1 and tong arm 23 is dismantled, can be obtained the spanner of four kinds of sizes, " one " font screwdriver 19 and " ten " font screwdriver 19, when using, can insert conversely by screwdriver 19 the pulling in hole 2 18 of internal angle wrench 5 tops, and easy to use.

Dismounting tong arm 1 and tong arm 23 o'clock, first nut 21 is outwards unscrewed, because screw rod 14 ends are provided with bearing pin 22, so nut 21 can not screw off screw rod 14, then the catch of clamping 20 is pushed aside, because the size of nut 21 and bearing pin 22 is all less than described jointed shaft 15, therefore nut 21 and bearing pin 22 need not be pulled down and one 7 points of tong arm 23 and tong arms can be opened, avoid pulling down the problem that part is easily lost.The independent tong arm 1 or the tong arm 23 that disassemble can be used as spanner, and binding clip 2 inner surfaces, wrench faces 1 and wrench faces 2 13 are working face.
