Detailed Description

The present invention will be further described with reference to the following specific examples. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.

A location footstock for gunstock auxiliary fixture for shooting training, the same with prior art is, be equipped with spout 2 on the location footstock 1, sliding connection has movable splint 3 on spout 2, be equipped with screw rod 4 in the spout 2, screw hole and screw rod 4 screw drive on the movable splint 3 are connected, 4 ends of screw rod set up knob 5.

The improvement point of the device is that: the middle part of the screw rod 4 is provided with an isolation block 6, the screw thread turning directions of the rod parts of the screw rod 4 at the two sides of the isolation block 6 are opposite, and the two movable clamping plates 3 are respectively in threaded connection with the rod parts of the screw rod 4 at the two sides of the isolation block 6; the tail ends of the two sides of the screw rod 4 are rotatably connected with the two sides of the top seat, and a knob 5 is arranged at one tail end of the screw rod 4; two openable dustproof rubber pads 7 are arranged on two sides of the opening at the top of the sliding groove 2. The top opening part both sides of spout 2 of this device are equipped with dustproof cushion 7, and two dustproof cushions 7 can open and shut, can not influence movable splint 3's slip positioning, only be in the state that opens and shuts at two dustproof cushion 7 of movable splint 3 department, movable splint 3 removes the back, and two dustproof cushion 7 of here can automatic elasticity be closed and seal the top opening part of spout 2 to can avoid 2 openings in top spout very easily to fall into dust sand and soil, guarantee that movable splint 3's regulation is smooth and easy.
