Description

Pencil defender

The utility model relates to a kind of writing function pen type defence device that has.

Known non-fatal defence device has explosion-proof rifle, anaesthetic rifle, Dagger pistol, lacrimation ejector, electric shock device etc., it launches the required percussion of self-defence material or igniter adopts powered battery to ignite, and its circuit complexity, the very much not portable band of volume, price height and user extremely change the hardship of battery.

The purpose of this utility model is to avoid the above-mentioned weak point of prior art, and a kind of writing function pen type defence device that has is provided.

Task of the present utility model is finished by following technical measures.

The utility model includes penholder, the pen cap, bar head, centre and has the nib of refill for ball-point pen, is fixed on pen clip on the pen cap with pin, lasso is arranged between the pen cap and the penholder and use thread connection, cooperating between nib and the penholder is to utilize the metal expansive force of nib to make the connection of nib insertion penholder.

Be provided with the push rod pipe of band thimble in the pen cap, and connect with the bar head, a spring is arranged in the push rod pipe, wear groove on the push rod pipe with screw thread, in its side, wear and have two block grooves on 90 ° of steering surfaces of groove over against pen clip: safety groove with pull the trigger groove.

The spring that groove pushes down wherein of wearing that one steady pin crosses the push rod pipe is fixed on the pen cap, and the gear sheet of pen clip upper end withstands in the safety groove or percussion groove on the push rod pipe.Placement one wherein has the bullet of gunpowder in the middle of the penholder.

Shoot or unload when playing, push rod is in first grade---and the position of insurance shelves, promptly the gear sheet on the pen clip withstands in the safety groove of push rod pipe, screws off penholder, packs into or unloads bullet, screws on penholder, just finishes the action of loading, unloading bullet.

The utility model compared with prior art has following advantage:

1, the utility model is the security personnel's equipment that integrates the work of writing and defend, daily common ball pen use, the defence device of can do self-defence again, avoiding invading and harassing done.

2, the defence of the emission in the utility model penholder material can be tear bombnoun, rubber bullet, plastics defence bullet, and nationality helps the elastic force percussion of push rod pipe medi-spring to upspring to break out and penetrates, and simple in structure, no complicated circuit and the trouble of changing battery are again the good merchantable brands of presenting friends.

The explanation of accompanying drawing drawing:

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the enlarged drawing of Fig. 1 middle and upper part structure.

To (in conjunction with the accompanying drawings) embodiment be described in detail below in conjunction with the utility model.

The utility model shown in Figure 1 includes nib ［ 2 ］, the pen cap ［ 7 ］, penholder ［ 10 ］, centre and has the nib 12 of refill for ball-point pen 13, is fixed on pen clip 6 on the pen cap 7 with pin 5, lasso 9 is arranged between the pen cap 7 and the penholder 10 and use thread connection.

The push rod pipe 3(that is provided with band push rod 3-1 in the pen cap 7 sees Fig. 2), and connect with bar head 2 with screw thread, spring 8 is arranged in the push rod pipe 3, wear groove 14 on the push rod pipe 3, in its side, wear and have two block grooves on 1490 ° of steering surfaces of groove: safety groove 16 and percussion groove 17 over against pen clip 6.

The spring 8 that groove 14 pushes down in the push rod pipe 3 of wearing that steady pin 4 crosses push rod pipe 3 is fixed on the pen cap 7.Pen clip 6 upper ends have gear sheet 6-1 withstand on the push rod pipe 3 safety groove 16 or the percussion groove 17 in.Place the bullet 11 that has gunpowder in the middle of the penholder 10.

The utility model can be write as ball pen at any time.

When shooting (or unloading bullet), the gear sheet 6-1 of pen clip 6 heads in the safety groove 16 of push rod pipe 3, screws off the pen cap 7, (or unloading) bullet 11 of packing into.

When as the defence emission, pull out bar head 2, the gear sheet 6-1 that the push rod pipe 3 that links with it spurs on pen clip 6 thereupon withstands in second grade of percussion groove 17 of push rod pipe 3, spring 8 in the push rod pipe 3 is in compressive state, aims at the mark, and presses pen clip 6 downwards, making it block sheet 6-1 deviates from from percussion groove 17, push rod pipe 3 is under unobstructed situation, and compression shape spring 8 wherein opens, and thimble 3-1 percussion bullet 11 on the push rod pipe 3 is detonated and launches.During urgent the emission, refill for ball-point pen 13 can be made the direct directive target of bullet.
