The specific embodiment

The utility model is described in more detail below in conjunction with the drawings and specific embodiments.

Be illustrated in figure 1 as the total figure of structure of present embodiment.

A kind of shockproof cutter; it comprises cutter hub 1; cutter hub 1 extends back the handle of a knife body; handle 3 outside outside the handle of a knife body, being provided with; outer handle 3 is wooden handle in the present embodiment; the handle of a knife body end is provided with screw thread; as shown in Figure 1 and Figure 4; outer handle 3 radially is provided with connecting hole 6; be provided with bolt 5 in the connecting hole 6; bolt 5 passes connecting hole 6 and fixes by screw thread with the handle of a knife body end; as shown in Figure 1, between connecting hole 6 and bolt 5, be provided with and be socketed in the flexible glue cover 4 that the bolt outer surface adopts soft rubber to make, flexible glue cover 4 is set bounce-back shaking force that cutter produced with by sword thing and chopping block collision the time is consumed vibration energy at flexible glue cover 4; the shaking force that reaches hand is eliminated or is reduced, thus protection user's health and improve and use comfort; prolong cutter life.

As Fig. 1, Fig. 6, Fig. 7, Fig. 8, Figure 11 and shown in Figure 12, described connecting hole 6 comprises extension 61 and card-tight part 62, the cross-sectional area of card-tight part 62 is greater than extension 61, bolt 5 comprises interconnective top 51 and body 52, the top 51 of card-tight part 62 and bolt closely cooperates and tightens outer handle 3, and the body 52 of bolt 5 passes extension 61 and fixes by screw thread with the handle of a knife body end.The afterbody of bolt 5 has the cavity 53 with handle of a knife body end threads engaged, and described cavity 53 inner surfaces are provided with the screw thread with handle of a knife body end threaded engagement, and handle of a knife body end and cavity 53 are fixed by screw thread.As Fig. 1, Fig. 9 and shown in Figure 10, flexible glue cover 4 comprises integrated buffering extension 41 and buffering card-tight part 42, buffering extension 41 is socketed in the outer surface of the body 52 of bolt 5, buffering card-tight part 42 is arranged on the card-tight part 62 of connecting hole 6, thereby the top of bolt 51 compresses the outer handle 3 of buffering card-tight part chucking.Also can keep the position of flexible glue cover 4 can not move during like this at cutter and by sword thing and chopping block collision, thus the service life of improving flexible glue cover 4.
