Gun bales catch trigger gear
Technical field
The present invention relates to a kind of gun bales catch trigger gear for starting dangerous gun.
Background technology
Public security organ needs to test to case-involving gun in the process of handling a case, as: find out ballistic characteristics etc., this just needs to pull the trigger gun, allows gun send bullet to study.In reality, there are some dangerous gun, if artificial these dangerous gun of percussion, sometimes reviewer caused damage, time serious, the even life of entail dangers to reviewer.
Summary of the invention
The object of this invention is to provide a kind of gun bales catch trigger gear, to solve in prior art when checking dangerous gun, artificial these dangerous gun of percussion cause damage to reviewer sometimes, time serious, and the even problem of the life of entail dangers to reviewer.
In order to realize above object, the present invention adopts following technical scheme: a kind of gun bales catch trigger gear, comprise grip base, grip base is fixed with the support upwards extended, the top slip cap of support is provided with guiding support, positioning and locking structure is provided with between support and guiding support, guiding support slides and is provided with the tooth bar moved horizontally, guiding support is rotatably equipped with the gear with tooth bar engaged transmission, gear be fixed on the motor-driven led on support and be connected, one end of tooth bar is fixed with the tommy bar stretching to side.
Described tooth bar is fixed with away from the other end of tommy bar the stroke alignment pin preventing tooth bar from throwing off with guiding support.
Described guiding support offers sliding eye, and described tooth bar is slidably arranged on guiding support by wearing in sliding eye, and the sidewall of guiding support offers the mounting groove communicated with sliding eye, and described gear is in mounting groove.
Described positioning and locking structure is top pressure screw rod, one end of screw rod to screw in the tapped through hole that described guiding support is arranged and with described support pressure tight fit, the other end of described screw rod is fixedly installed and screws handwheel.
Be provided with sheathed through hole in described grip base, the side screw thread of grip base is installed with dog screw, and the inner termination of dog screw stretches in sheathed through hole, and the other end of described dog screw is fixedly installed rotation hand wheel.
The starting switch of described motor is remote control switch.
When using the present invention to carry out the percussion of dangerous gun, to fix for gun, also the present invention is fixed simultaneously, tommy bar is contacted with the trigger of gun, then starter motor, motor driven gear rotates, gear driven tooth bar moves, and tommy bar moves cocking together with tooth bar, realizes the object of percussion gun, no longer need manually to pull the trigger gun, there will not be casualties.
Tooth bar is fixed with away from the other end of tommy bar the stroke alignment pin preventing tooth bar from throwing off with guiding support, forms alignment pin and tooth bar can be prevented to be separated with guiding support, ensure reliable operation of the present invention.
The starting switch of motor is remote control switch, and reviewer can the startup of far distance controlled motor, even if gun generation dangerous situation, and also can not crisis reviewer.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of the embodiment of the present invention.
Detailed description of the invention
A kind of embodiment of gun bales catch trigger gear, in FIG, its grip base 4 entirety is square, grip base is fixed with support 2, support 2 is shaft-like, one end of support 2 is fixed on grip base 4, one end upwards extends in addition, guiding support 8 is provided with at the top slip cap of support 2, the overall cuboid of guiding support 8, its length direction is vertical with support 2, guiding support 8 is provided with the hole supplying the upper end of support 2 to pass at one end, the sidewall of guiding support 8 is installed with top pressure screw rod, one end of screw rod screws in the tapped through hole that guiding support 8 is arranged, top pressure screw rod screw in guiding support 8 inner termination and with support 2 compression fit, realize the positioning and locking between support 2 and guiding support 8.The external end head of screw rod is fixedly installed and screws handwheel 9, the length direction of guiding support 8 offers sliding eye, sliding eye extends to the other end due to the one end of support 8 of leading, slide in sliding eye and be inserted with tooth bar 1, the sidewall of guiding support 8 offers mounting groove, and mounting groove communicates with sliding eye, in mounting groove, be provided with gear, pinion rotation is assemblied on guiding support 8, wheel and rack engaged transmission.Guiding support 8 is fixedly installed motor 6, and the output shaft of motor 6 is connected with the wheel shaft of gear by speed reduction gearing, and driven wheel rotates.
Be fixed with the tommy bar 3 stretching to side in one end of tooth bar 1, the other end of tooth bar 1 is provided with stroke alignment pin 7, stroke alignment pin 7 is thrown off with guiding support 8 in order to prevent tooth bar 1.
In grip base 4, be provided with sheathed through hole, the side screw thread of grip base 4 is installed with dog screw, and the inner termination of dog screw stretches in sheathed through hole, and the other end of dog screw is fixedly installed rotation hand wheel.
In use, dangerous gun are fixed on shooting stand 5, and shooting stand 5 is located in sheathed through hole, adjustment position with dog screw by shooting stand with step up base and fix, then starter motor just can pull the trigger gun.Meanwhile, the position between grip base and support can adjust.
The starting switch of the motor in the present embodiment is remote control switch, can certainly be hand switch, because hand switch also can be arranged on the position away from motor.
Be a kind of concrete product structure disclosed in the present embodiment, certain the present invention is claimed is not limited in concrete form disclosed in the present embodiment.
