The specific embodiment

The specific embodiment of the present utility model: as shown in Figure 1, 2, a kind of tweezers of peeling off, include two plastics tweezer arms 1, a wherein end of described plastics tweezer arm 1 is fixedly connected, plastics tweezer arm 1 relies on the open-shaped attitude of elastic force, the other end of described plastics tweezer arm 1 is provided with metal tweezer head 2, and described metal tweezer head 2 extends to described plastics tweezer arm 1 inside, and described plastics tweezer arm 1 inboard opposite face is provided with the detent mechanism that prevents plastics tweezer arm 1 relativity shift.

As shown in Figure 3, in this specific embodiment, it is leg-of-mutton double wedge 21 that a described wherein metal tweezer head 2 is provided with the cross section, and another metal tweezer head 2 is provided with the groove 22 that is complementary with described double wedge 21.Described detent mechanism has two kinds of embodiments: first kind of embodiment is: vertically be provided with two datum levels that are parallel to each other vertically on a plastics tweezer arm 1 medial surface therein, constitute described detent mechanism with a side of a described wherein datum level, two confined planes that the opposite side of another datum level fits respectively when being provided with in 2 clampings of metal tweezer head on another plastics tweezer wall 1 medial surface.In this specific embodiment, one in front and one in back two catch vertically are set on a plastics tweezer arm 1 medial surface therein vertically, one side of being departed from back catch 4 by preceding catch 3 vertically constitutes described two datum levels with the side that back catch 4 departs from preceding catch 3 vertically, on another plastics tweezer arm 1 medial surface, be provided with and staggered one in front and one in back two the spacing catch that cooperate of described two catch, constitute described two confined planes near a side of front limit catch 5 vertically near the spacing catch 6 in a side and back of the spacing catch 6 in back vertically by front limit catch 5.Two catch or two spacing catch can certainly be processed as one, described catch and spacing catch will guarantee before metal tweezer head 1 clamps for the processing of height, catch and spacing catch have begun mutual applying, could guarantee that like this plastics tweezer wall 1 can relativity shift, be provided with on the plastics tweezer wall of catch for described spacing catch buffered cushion space being provided with, be provided with on the plastics tweezer wall of spacing catch for described catch buffered cushion space being provided with, cushion space described here is for being provided with groove 7 in described plastics tweezer wall 1 inboard relevant position, like this when metal tweezer head 2 clamps, plastics tweezer wall 1 still can push to the inside, and it is tighter to make that metal tweezer head 2 presss from both sides.As Fig. 4,5,6, shown in 7, second kind of embodiment is for being extended with a projection 8 on a plastics tweezer arm 1 medial surface therein on another plastics tweezer arm, described projection 8 is provided with a groove 9, by described groove 9 parallel axes to two opposite faces constitute described two datum levels, described another plastics tweezer arm 1 medial surface is provided with the card 10 that is complementary with described groove 9, described groove 9 length vertically is greater than card 10 length vertically, by being parallel to of described card 10 two axial faces constitute described two confined planes, described card 10 will make before metal tweezer head 2 clamps for the processing of height, card 10 has begun to enter in the described groove 9, could guarantee that like this plastics tweezer wall 1 can relativity shift.Be provided with in the described groove 9 for described card 10 buffered cushion spaces, cushion space described here is for when metal tweezer head 2 has clamped, described card 10 is also for being inserted into fully in the groove 9, also want segment space to insert in the groove 9 for card 10, after metal tweezer head 2 clamps, plastics tweezer wall 1 still can push to the inside, and metal tweezer head 2 can hold tighter.Described plastics tweezer arm 1 lateral surface is provided with asperities 11, like this when plastics tweezer wall 1 pushes to the inside, because the frictional force between finger and the plastics tweezer wall 1 is bigger, can guarantee that plastics tweezer wall 1 can not slip out of the hand, and makes work efficiency higher.
