Description

The cutter of the handle of a knife amounted to of improvement

The utility model relates to a kind of cutter of amounting to handle of a knife.

At present, the cutter of commonly using of amounting to handle of a knife 1, as shown in Figure 1, has the shank part 10 that slightly is plate shaped, one end appropriate location of contiguous shank part 10 blade 11 that then is pivoted, the central appropriate location of this shank part 10 is provided with the hole 12 of a hollow out, and the 13 ora terminalis places, articulated section of these hole 12 contiguous blades 11, then extend vertically downward, the setting of borrowing this hole 12 with make shank part 10 below form a shell fragment 14, the one end order of this shell fragment 14 upwards slightly is little curved state, to make it have elasticity, and then make this shell fragment 14 form a stop section 15 at the one end, this stop section 15 just can lean with the ora terminalis place of open blade 11 articulated sections 13, is fixed can borrow stop section 15 after making blade 11 open.

One end appropriate location of the contiguous blade 11 in shank part 10 tops is provided with a projection 16, borrow projection 16 when stretching out, can keep the state of a location with shank part 10 to make blade 11, in addition shell fragment 14 not with blade 11 against an end back side then be provided with several recessed handles 17, to increase the elasticity of shell fragment 14.

The cutter 1 of the above-mentioned handle of a knife of commonly using amounted in use, as Fig. 2, shown in 3, when the user when holding shank 10, user's thumb then props up the back of blade 11, at this moment, the forefinger application of force of holding this shank part 10 is bigger, then can make shell fragment 14 press down, and then cause the stop section 15 of shell fragment 14 to be separated with the 13 ora terminalis places, articulated section of blade 11, and thumb props up the strength that execute at blade 11 backs, the military order blade folds downwards, and then cause the thing of incised wound finger to take place, so the cutter 1 of the handle of a knife of commonly using amounted to has danger to user's finger in use.

In view of this, the purpose of this utility model provides a kind of cutter of the handle of a knife amounted to of improvement, and it is to borrow to push steel ball, make the end of shell fragment and blade bottom end fate from, blade is folded in the accommodation space between shank part and lid, incised wound finger when avoiding blade to fold downwards.

The purpose of this utility model is achieved in that a kind of cutter of the handle of a knife amounted to of improvement, it is to be made of shank part and the blade that is articulated thereof, it is characterized in that: the shank part middle position is provided with the hole of a hollow out, between this hole, be provided with a shell fragment that joins with one end and shank part, and the other end of this shell fragment make progress little curved end and blade bottom ora terminalis mutually against.

The little bent-up end portion that makes progress of described shell fragment is provided with an annular recess, and this annular recess is provided with a convex body.

Described shank part is provided with a lid, and the convex body place of the corresponding shell fragment of this lid is provided with a through hole, is provided with a steel ball in this through hole.

Described through hole upper limb diameter is less than the lower edge diameter, and described diameter of the steel ball is greater than through hole upper limb diameter.

Be exposed at through hole outside the top of described steel ball, the convex body of the bottom of steel ball and shell fragment leans again.

It is one plate shaped that described shank part is.

Contiguous blade one end in described shank part top is provided with a projection.

Described shell fragment and shank part joint are provided with a concave surface.

The other end of described shell fragment is provided with a stop section, and this stop section and blade bottom ora terminalis mutually against.

Owing to adopt such scheme: guarantee safe in utilization and convenience.

Below in conjunction with drawings and Examples the utility model is further specified.

The cutter outside drawing of the handle of a knife amounted to that Fig. 1 commonly uses;

A kind of user mode figure of the handle of a knife amounted to that Fig. 2 commonly uses;

But the another kind of user mode figure of the jack knife that Fig. 3 commonly uses;

Fig. 4 is the utility model exemplary embodiments exploded view;

Fig. 5 is the A-A cutaway view of the utility model exemplary embodiments Fig. 4;

Main element figure number: 20. shank parts, 21. blades, 23. shell fragments, 28. lids

As Fig. 4, shown in 5, the cutter 2 that present embodiment can be amounted to handle of a knife is to be provided with the shank part 20 that slightly is plate shaped, one end appropriate location of contiguous this shank part 20 blade 21 that then is pivoted, the hole 22 that these shank part 20 adjacent central appropriate positions are provided with a hollow out and slightly take the shape of the letter U, then be provided with the shell fragment 23 that an end and shank part 20 connect 22 of this holes, the other end of this shell fragment 23 then upwards slightly is little curved state, to make it have elasticity, and then form a stop section 24 at the other end of shell fragment 23, and this stop section 24 just can with open blade 21 bottom ora terminalis 211 mutually against, be fixed can borrow stop section 24 after making blade 21 open.

Contiguous blade 21 1 end appropriate locations above shank part 20, be provided with a projection 25, borrow projection 25 to make blade 21 when stretching out, can keep the state of a location with shank part 20, in addition, the other end appropriate location of contiguous shell fragment 23, be provided with an annular recess 26, this annular recess 26 is provided with a convex body 261, and in addition, shell fragment 23 is at the bottom appropriate location, be provided with a concave surface 27, so as to increasing the elasticity of shell fragment 23.

Shank part 20 is provided with the lid 28 of a cooperation shank part 20, this lid 28 is in convex body 261 appropriate positions of corresponding shell fragment 23, be provided with a through hole 281, this through hole 281 is the state (as shown in Figure 5) that is the upper limb diameter and is slightly less than lower edge, to make a diameter be slightly larger than the steel ball 29 of through hole 281 upper limb diameters, can stably block and establish wherein and unlikely skidding off, and the top 291 of steel ball 29 is the outer through hole 281 that is exposed at, be beneficial to user's finger presses, again the bottom 292 of steel ball 29 be with shell fragment 23 annular recess 26 on convex body 261 lean, borrow and push steel ball 29, make shell fragment 23 press down.

In use, the blade 21 of stretching out be with the stop section 24 of its bottom ora terminalis 211 and shell fragment 23 mutually against, with the blade 21 of fixedly stretching out, when user's desire folds blade 21, system is with the top 291 of thumb press steel ball 29, after making steel ball 29 be pushed, the bottom 292 of steel ball 29 presses down the convex body 261 of shell fragment 23 again, and then, the stop section 24 of shell fragment 23 is separated with the bottom ora terminalis 211 of blade 21, at this moment, push the back of blade 21 again with forefinger, can make blade 21 fold in the accommodation space 201 of 28 of shank part 20 and lids.

Borrow set lid 28 and steel ball 29 on the shank part 20, to make the user safer in when operation, therefore, it is excessive because of the finger application of force to improve the user, and shell fragment 23 is depressed, cause blade 21 to fold downwards, cause the thing of incised wound finger to take place, and on overall structure, can make user's hand more firmly grip, simultaneously, also can make the user convenient when folding blade 21, and then improve the convenience on using.
