A kind of operating forceps of the leaf spring mechanism of band four described herein, including first handle 5 and second handle 6, two Four leaf spring mechanisms are provided between handle, four leaf spring mechanisms include being oriented to reed 1, tensioning reed 2, sliding reed 3 and are connected to Sliding block 4 between tensioning reed 2 and sliding reed 3, first handle 5 is to be hinged with the left-hand end of second handle 6, first handle 5 The position being hinged with second handle 6 is provided with hollow stem 9, and the downside of second handle 6 is provided with button 7, pull bar 8 is provided with hollow stem 9, The left side termination of hollow stem 9 is provided with pincers 10；It is strong with recovery, deformation is not susceptible to, uniform force during stretching, service life is held Long, safe effect.

In the embodiment of the present application, shown in Fig. 1 ~ Figure 10, a kind of operating forceps of the leaf spring mechanism of band four, including it is first-hand Handle 5 and second handle 6, are provided with four leaf spring mechanisms between two handles, four leaf spring mechanisms include being oriented to reed 1, tensioning reed 2, Sliding reed 3 and the sliding block 4 being connected between tensioning reed 2 and sliding reed 3, it is characterised in that：First handle 5 and second To be hinged, first handle 5 is provided with hollow stem 9, the downside of second handle 6 to the left-hand end of handle 6 with the position that second handle 6 is hinged Button 7 is provided with, pull bar 8 is provided with hollow stem 9, the left side termination of hollow stem 9 is provided with pincers 10.

Four leaf spring mechanisms are controlled using the extruding between first handle 5 and second handle 6, wherein, four leaf spring machines Structure plays main support by two splay spring leafs.

Clamping positioning is carried out to the termination of pull bar 8 using the sliding block 4 being tensioned between reed 2 and sliding reed 3.And then realize Left and right stretching to pull bar 8.Wherein, the right end of hollow stem 9 is arranged on the interposition that first handle 5 is hinged with second handle 6 Put, pull bar is supported using the hollow stem 9 of intermediate position, recycle the pincers 10 of the left end of hollow stem 9 to be clamped, pull bar 8 are used to be controlled the state of pincers 10.

Four leaf spring mechanisms include being oriented to reed 1, tensioning reed 2, sliding reed 3, saddle 4, are installed by four leaf spring mechanisms Between first handle 5 and second handle 6 and then realize regulation to sliding block 4, the tensioning to pull bar 8.

Tensioning reed 2, sliding reed 3 are in X-shaped with saddle 4, in support and the reply structure of four flat springs.

Reed 1, tensioning reed 2, sliding reed 3, saddle 4 are directed to using first handle 5 and second handle 6 be enclosed in two Between person, the building enclosure of stabilization is formed.

Gloves will not be damaged, and tensioning reed 2, sliding reed 3 are arranged on first handle 5 and second by the way of clamping In handle 6.

Tensioning reed 2, sliding reed 3 are in splayed structure, the effect with tensioning.Be tensioned reed 2 centre position to Upper to be fixedly connected with the downside of saddle 4, the upside of the centre position of sliding reed 3 downwards with saddle 4 is fixedly connected, fixation company The mode of connecing can be by the way of welding, it would however also be possible to employ the directly fixed mode of bolt.I.e. tensioning reed 2, sliding reed 3 exist During motion, the gloves of operating personnel will not be damaged.Security is higher.And can improve tensioning reed 2 using splayed, slide spring The reply intensity of piece 3.Wherein, tensioning reed 2, sliding reed 3 are made using spring leaf, and simple structure is easily achieved.

Fixation is connected in the left side of first handle 5 left end of sliding reed 3 upwards, and the right-hand member of sliding reed 3 is sheet Structure, the right-hand member of sliding reed 3 is plugged in the groove that first handle 5 is recessed upwards, and the right-hand member of sliding reed 3 is because extruding causes to slide The right-hand member of reed 3 is horizontally slipped along the groove of first handle 5.
