After adopting said structure, the utility model makes two housings when fastener activated because of second flexible member is set between two housings, can separate automatically, thereby make things convenient for the user to take two housings apart.In addition, the utility model makes two housings of hand knife can make things convenient for, promptly snap together because of the structure and the setting of action button.

Below in conjunction with drawings and Examples, the utility model done describing in further detail.

Fig. 1 is a kind of exploded view of hand knife rapid dismounting apparatus;

Fig. 2 is the floor map of Fig. 1;

Fig. 3 is a part section action schematic diagram one among Fig. 1;

Fig. 4 is a part section action schematic diagram two among Fig. 1.

See also shown in Fig. 1 to 3, the hand knife rapid dismounting apparatus mainly comprises a hand knife body 1, and two

housings

10,40 that this body 1 has can combine apace.

Wherein, be provided with a chute 12 in the front end of

housing

10,40, chute 12 can be for the sliding tool rest 14 of establishing a blade 22.

Be provided with more than one depression 16 and more than one male member 18 in housing 10 front end inboards.

These tool rest 14 tail ends extend an elastic arm 15, elastic arm 15 is established a button 17, but button 17 voltage supply are moved, are promoted and the action of control tool rest 14, also establishing one on the elastic arm 15 can be for the backstop 20 of the arbitrary depression 16 of scarf, tool rest 14 is fixed in the

housing

10,40, more can adjust tool rest 14 and stretch into or protrude from

housing

10,40 distance outward, to make things convenient for the user to select for use or to operate.When button 17 pushed away the depression 16 of housing 10 with the backstop 20 of elastic arm 15, tool rest 14 can be promoted by

housing

10,40 relatively, up to backstop 20 scarves till the another one depression 16.This tool rest 14 also can extend a block piece 23 in addition, for pothole 19 the insides that embed housing 10, makes tool rest 14 be fixed on the place, location with respect to housing 10, makes that tool rest 14 still can be stabilized in and be fixed to housing 10 when housing 40 is separated housing 10.

Housing

10,40 front ends respectively are provided with one and collude

part

24,42 and can supply mutual hook, make the front end of

housing

10,40 can form the button hook structure of detachable formula, it mainly is that the front end that can prevent two

housings

10,40 is done relative motion up and down, and only allows one of them housing 10 to move with respect to another housing 40 backward.This

part

24,42 that colludes can be arranged on respectively on the

different housing

10,40 accordingly, as long as can hook live the front end position of two housings 10,40.The tail end of two

housings

10,40 is preferably respectively established a recess 26, and for a ccontaining flexible member 28, this flexible member 28 can flick the tail end of two housings 10,40.The tail end of two

housings

10,40 is also respectively established a groove 30,44.Housing 40 rear ends preferably are convexly equipped with a male member 46, and preferably stretch in the groove 44.10 of housings have a nose bar 31, can be pivoted to the tail end of housing 10 for an action button 34 by a pivot 35.Certainly, action button 34 can also not need nose bar 31 and directly or by alternate manner be pivoted to housing 10.But its male member 46 of tail end, particularly buckle of an end 36 buckle housings 40 of action button 34, and two

housings

10,40 can be combined apace.Another flexible member 33 is arranged between action button 34 and the housing 10, urges its male member 46 of tail end, particularly buckle of buckle housing 40 will move an end 36 of button 34, and can more easily two

housings

10,40 be combined apace.Wherein the distal portion of flexible member 33 preferably firmly is arranged on groove 32 the insides of action button 34 and housing 10.The backstop 37 that 38 of the other ends of action button 34 can touch housing 10 for the rotational action of limit movement button 34, and can prevent that flexible member 33 from exceedingly being urged.

During action, please consult shown in Figure 3, flexible member 33 can force an end 36 of action button 34 to remove another housing 40 of buckle, and flexible member 28 can relatively force housing 40, particularly male member 46 removes an end 36 of snap action button 34, so makes two

housings

10,40 very firmly to combine.When the other end 38 of action button 34 is moved and when urging flexible member 33, one end 36 of action button 34 can break away from housing 40, and making flexible member 28 can automatically two

housings

10,40 be flicked (see figure 4), therefore the user can separate

housing

10,40 easily.And in the time will assembling, the user only needs the tail end of housing 40 is pressed to the tail end of housing 10, makes an end 36 of action button 34 cross or withhold the tail end of housing 40, can easily two

housings

10,40 be combined again fast.

In addition, the guiding face 48 of an inclination or arc is established at the position that is preferably in male member 46 close another housings 10, please consults Fig. 3,4 especially, so that the tail end of housing 40 can be crossed and withhold to an end 36 of action button 34 more easily, particularly blocks its male member 46.Action button 34 can be contained in

groove

30,44 the insides of

housing

10,40 just, and can prevent that it from being moved accidentally.Certainly, it also can direct protruding dew and is not needed to be provided with

groove

30,44, is moved accidentally and otherwise avoid moving button 34.Though

flexible member

28,33 is embodiment with snail volume flexible member in the drawings, but it can also be the flexible member of various difformities, form or structure, the flexible member of spring-piece type etc. for example.

In addition, should be noted that: though this tool rest 14 is showed among the figure with slideable structure, it also can be provided with fixed.

Because main feature of the present utility model is the feature that is that its action button 34 buckle housings 40 and flexible member 28 can be separated two

housings

10,40, so no matter other each modular construction as where conversion or modification, can supply two structures that housing 10,40 flicks as long as the action button 34 that flexible member urges is set and a flexible member 28 is set, all will be included in the category of the present utility model.
