In order to achieve the above objectives, the jackknife of the utility model, including handle, the folding part equipped with cutting edge, pivot, it is described Handle includes two shank bodies, and the folding part is clamped in by the pivot between two shank bodies, two shank bodies Between form the space for storing the folding part, it is characterized in that：The folding part is contacted with shank body by bump structure.

As optimization technique means：The bump structure is multiple and is evenly distributed on around the pivot.

As optimization technique means：At least side of the folding part is connect with the shank body by the bump structure It touches.

As optimization technique means：The shank body, folding part are structure as a whole, and the bump structure is directly made In the shank body or folding part.

As optimization technique means：The shank body includes gasket, the bump structure system on the gasket simultaneously It is contacted with the folding part.

As optimization technique means：The folding part includes gasket, and the bump structure system is on the gasket And it is contacted with the shank body.

As optimization technique means：The shank body includes gasket, and the bump structure system is on the folding part And it is contacted with the gasket.

As optimization technique means：The folding part includes gasket, and the bump structure system is in the shank body And it is contacted with the gasket.

As optimization technique means：The shank body includes the retainer of assembly on it, and the bump structure is embedding Pellet on the retainer, the pellet contact on the folding part.

As optimization technique means：The folding part includes the retainer of assembly on it, and the bump structure is The pellet being inlaid on the retainer, the pellet contact in the shank body.

The utility model is contacted with shank body by bump structure by folding part, reduces folding part in opening and closing process In frictional force with handle junction so that the folding part opening and closing of jackknife are more easily laborsaving, and user can realize list Hand operates, and extends the service life of the parts such as blade and handle.

Specific implementation mode

The utility model is described further below in conjunction with Figure of description.

As shown in Figs. 1-3, it is a kind of structural schematic diagram of the utility model jackknife；It includes handle 01, is equipped with cutting edge 21 Folding part 2a, pivot 3a, handle 01 includes two shank body 11a, between folding part 2a is clamped in two shank body 11a by pivot 3a, Pivot is generally docked by screw thread from axial, therefore two shank bodies can be enabled to clamp folding part by screw thread, it is illustrated that The cutting edge 21 of folding part is directly opened cutting edge of a knife or a sword on folding part and is formed, and cutting edge may be alternatively provided on blade and assemble blade when specific implementation As the composition part of folding part on folding part, two shank body 11a are component in figure, respectively by the plate of inside and outside Gripping member is constituted, when specific implementation can the plate of inside and the gripping member in outside can be a component, shape between two shank bodies At the space of storage folding part, folding part 2a is contacted with shank body 11a by bump structure 41.

As Figure 2-3, shank body 11a includes the retainer 13 of assembly on it, and bump structure 41 is to be inlaid in retainer Pellet on 13, pellet contact on folding part, so as to reduce folding part during opening and closing with handle Frictional force.As the equivalent way of the structure, folding part includes the retainer of assembly on it, and bump structure is to be inlaid in holding Pellet on frame, pellet contact in shank body.

It is another structural schematic diagram of the pivot 3b connecting portions of the utility model jackknife as shown in Figure 4；The structure In shank body 11b include gasket 12b, the system of bump structure 42 contacts on the 2b of folding part and with gasket 12b.

It is the third structural schematic diagram of the pivot 3c connecting portions of the utility model jackknife as shown in Figure 5；The structure In folding part 2c include gasket 22c, the system of bump structure 43 contacts on shank body 11c and with gasket 22c.

It is the 4th kind of structural schematic diagram of the pivot 3d connecting portions of the utility model jackknife as shown in Figure 6；The structure In shank body 11d include gasket 12d, the system of bump structure 44 contacts on gasket 12d and with folding part 2d.As equivalent replacement Means, folding part include gasket, bump structure system gasket on and contact with shank body.

In view of the enlightenment of above structure, shank body, folding part are structure as a whole, bump structure directly make in shank body and with Folding part contacts or bump structure directly system contacts on folding part with shank body.

Aforementioned various structures in the specific implementation mode, bump structure is multiple and is evenly distributed on around pivot, is made Obtain position uniform force when pivot is tightened.

In Fig. 3-6, the both sides of folding part are contacted by bump structure with shank body, when it is implemented, also can only enable folding The side in portion is contacted with shank body by bump structure.

The jackknife of above-mentioned various structures is contacted with shank body by bump structure by folding part, with a hand when use Handle is held, folding part can be enabled to be unfolded or collapsed into handle from handle using pivot as rotation center by whipping.
