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 the utility model embodiment.

A kind of cutter of replaceable outer handle, 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, the handle of a knife body end is provided with screw thread, and as Fig. 9 and shown in Figure 11, outer handle 3 radially is provided with connecting hole 5, be provided with bolt 4 in the connecting hole 5, bolt 4 passes connecting hole 5 outer handle 3 and handle of a knife body end being installed together by threaded connection detachable.

As Fig. 1, Figure 15 and shown in Figure 16, described connecting hole 5 comprises extension 51 and card-tight part 52, the cross-sectional area of card-tight part 52 is greater than extension 51, bolt 4 comprises interconnective top 41 and body 42, the top 41 of card-tight part 52 and bolt closely cooperates and tightens outer handle 3, and the body 42 of bolt 4 passes extension 41 outer handles 3 and handle of a knife body end being installed together by threaded connection detachable.The afterbody of bolt 4 has the cavity 43 with handle of a knife body end threads engaged, and described cavity 43 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 43 are fixed by screw thread.

As shown in Figure 2, for ease of assembling, the screw thread of handle of a knife body end is two pitch threads, and the screw thread of described bolt 4 is two pitch threads.

As Fig. 1 and Fig. 3～Figure 5 shows that cutter hoop that first embodiment of the utility model adopts, cutter also comprises the cutter hoop 2 that is arranged on outer handle 3 outer surfaces, cutter hoop 2 is arranged on the connecting portion of outer handle 3 and handle of a knife body, promptly outer handle 3 is connected the connecting portion of transition part 5 with handle of a knife, cutter hoop 2 one ends are connected with outer handle 3, and the other end is connected with cutter hub 1.Cutter hoop 2 plays the point action that contacts with cutter hub 1, and when making the firm wooden handle of bolt, the cutter hoop is set in the wooden handle appearance, and this position is strengthened, and props up then and withstands on cutter hub, makes hilt firm.

As Fig. 6～cutter hoop that is depicted as second embodiment employing of the utility model shown in Figure 8.

As Fig. 9～shown in Figure 14, outer handle 3 can have multiple choices, can adopt cylindrical, also can flat column.The outer surface of handle 3 can also be provided with the anti-skidding twill of the multiple tracks projection that is made of one piece with outer handle 3 outside.

The more than round wooden handle of the design of replaceable handle of a knife, other cutter also can be rolled over dress and change handle, but, round wooden handle mostly is specialty and uses cutter, and its meaning is bigger on feel, as moulds handle folding dress and change, its meaning is then cleaned at disassemble, changing size or handle material material, style sample etc., is exactly environmental protection in addition, separable steel, moulds reclaiming.In addition, the design of folding hilt reduces production process, and assembling reduces cost the easy standardized production of product easily.

As mentioned above, just can realize the utility model preferably, the foregoing description is preferred embodiment of the present utility model only, is not to be used for limiting practical range of the present utility model; Be that all equalizations of being done according to the utility model content change and modification, all contained by the utility model claim scope required for protection.
