Description

Self-opened telescopic dagger

The utility model belongs to a kind of police and uses apparatus, particularly relates to a kind of from driving flexible dagger.

Existing eject dagger is the elastic force that utilizes an extension spring, and blade is advanced with respect to hilt ejection, bullet.No sheath, blade contracts in hilt at ordinary times, blade can be ejected during use, owing to be to refer to promote pushing block by mother move and elongate extension spring and produce elastic force, reach the purpose that passes in and out cutter, when holding dagger, mother refers to that operating range is limited, so it is shorter to have limited actuating length, the elastic force deficiency of generation causes out that cutter speed is slow, strength is little.The deflection of extension spring has only 10 millimeter, and the stroke of turnover cutter is generally more than 100 millimeters, be that blade is in running, the elastic force of extension spring blade uses has only 10 millimeters stroke, and all the other strokes are realized by inertia, as run into obstruction, overcome inertia, then blade can not put in place, is in free state, and ineffective.Because no sheath in the leather sheath of can only packing into when carrying or in the pocket, does not therefore reach the purpose that promptly goes out cutter.

The purpose of this utility model provides that a kind of use is the most convenient, and it is fast to go out cutter, flexibility and reliability drive flexible dagger certainly.

Technical solution of the present utility model is: a kind of from driving flexible dagger, by hilt 1, the hilt 3 that is fixedly connected with hilt 1, place blade 8 and coil tension spring 2 between hilt 1 and 3 to form, it is characterized in that: button 13 and 1 movable connection of hilt, be provided with spring 14 between one end of button 13 and the hilt 1, the other end of button 13 is provided with hook 19, also be provided with button 9 on the hilt 1, between button 9 and the hilt 1 spring 11 is housed, button 9 joins with button pawl 7, blade 8 is provided with knife-edge 10 and locating hole 20, sheath 15 is fixedly connected with hold(ing)-down clip 17, hold(ing)-down clip 17 is provided with push type broach board slot 16, locating piece 5 is equipped with in the relevant position of hilt 3, between locating piece 5 and the hilt 3 spring 6 is housed.

Described coil tension spring 2 joins to holding with blade 8 backing pin 4 is housed, backing pin 4 and 8 movable connections of blade.

Described sheath 15 joins with belt card 18.

The utility model compared with prior art has easy to carryly, goes out that cutter is fast, the advantage of flexibility and reliability, is specially adapted to the sudden state of emergency and uses.

Below in conjunction with drawings and Examples the utility model is described further: a kind of from driving flexible dagger, by hilt 1, the hilt 3 that is fixedly connected with hilt 1, place blade 8 and coil tension spring 2 between hilt 1 and 3 to form, it is characterized in that: button 13 and 1 movable connection of hilt, be provided with spring 14 between one end of button 13 and the hilt 1, the other end of button 13 is provided with hook 19, also be provided with button 9 on the hilt 1, between button 9 and the hilt 1 spring 11 is housed, button 9 joins with button pawl 7, blade 8 is provided with knife-edge 10 and locating hole 20, sheath 15 is fixedly connected with hold(ing)-down clip 17, hold(ing)-down clip 17 is provided with push type broach board slot 16, locating piece 5 is equipped with in the relevant position of hilt 3, between locating piece 5 and the hilt 3 spring 6 is housed.

Described sheath 15 joins with belt card 18.

As shown in Figure 1: 1,3 is hilt, select aluminium alloy material for use, form through microdiecast, appearance can be inlaid with the camouflage color engineering plastics ABS, and is cool excessively to prevent winter from using hilt, button 13,9 and button pawl 7 are Fine Steel Casting iron, button 13 connects by push button shaft 12 and hilt are movable, and the material of blade 8 is No. 70 Fine Steel Casting irons, reaches HR52～58 through heat treatment hardness, to guarantee to have certain intensity and hardness, chrome-faced corrosion protection.Sheath 15 is an engineering plastics ABS, with bolt hold(ing)-down clip 17 and sheath 15 is fixedly connected, and the material of pressure plare 17 is a Fine Steel Casting iron, and heat treatment hardness is HRC43～48, and belt card 18 is a stainless steel material, with 15 movable connections of sheath.

Its operation principle is: as shown in Figure 1: in the time of in needs blade 8 is withdrawn hilts, blade 8 is inserted in the sheath 15, hold(ing)-down clip 17 inserts between the hilt 1 and 3 simultaneously, pass through (as shown in Figure 5) from the right angle of button pawl 7, and back down locating piece 5, make spring 6 compressions, locating piece 5 promptly spins off (as Fig. 3 in the locating hole 20 from the blade 8, shown in 2) hold(ing)-down clip 17 continues to move forward, push up backing pin 4 ends to the top, this moment, coil tension spring 2 was compressed, because backing pin 4 connects (as shown in Figure 4) with blade 8 activities, blade 8 can move with backing pin 4, enters in the hilt, when knife-edge 10 moves to hook 19 places on the button 13, because the elastic force of spring 14 makes hook 19 hook blade 8, unlikely ejection, simultaneously button pawl 7 is meshed (as shown in Figure 6) with push type broach board slot 16 on the hold(ing)-down clip 17, sheath 15 unlikely coming off are enclosed within belt card 18 on the waistband, can carry.

When needs use, press the button 9, make button pawl 7 break away from push type broach board slot 16, can from sheath, extract dagger, this moment, blade 8 exposed three/part, operation such as can prize, dial, and also can carry out non-fatal thorn to hit, when all going out cutter as needs, press the button 13, make spring 14 compressions, hook 19 is deviate from knife-edge 10, coil tension spring 2 ejects blade 8, after putting in place, spring 6 pins the locating hole 20 interior location that locating piece 5 springs into blade 8, as button 9,13 is pressed simultaneously, once can put in place by full cutter, it is very rapid to go out cutter.
