A left foot frame 3 is provided on the left side of the rotation support 1.

The bipod frame for the gun provided by the embodiment can straighten the left and right foot frames and mount the gun barrel to normally aim when being used at ordinary times. The following is an explanation of the operation principle with respect to three innovative points.

When the two-leg stand needs to be lengthened, referring to fig. 4, the right unlocking block is pressed, the guide pin on the unlocking block moves downwards, the guide pin is separated from the step dead angle of the chute downwards and enters the straight path of the chute, when the support rod seat 9 is pulled to the required height, the right unlocking block is released, the right unlocking block supports against the step dead angle of the chute 15 again under the pressure of the spring at the moment, the support rod is locked, and the height of the right-leg stand is fixed, so that the purpose of adjusting the height is achieved.

When the angle of the rotary unit needs to be rotated, please refer to fig. 7, press the hand-turning block 20 upwards, move the central shaft rod 19 upwards, under the pressure of the upper compression spring 17, lift up the 8 convex teeth 28 of the upper base 22, separate from the 8 grooves 27 of the lower base 21, rotate the hand-turning block 20 by about 45 degrees, put down the hand-turning block 20, at this time, the 8 convex teeth 28 of the upper base 22 and the 8 grooves 27 of the lower base 21 are re-engaged, under the pressure of the lower compression spring 18, the rotary support part 1 is re-fixed, at this time, the rotary unit rotates by 45 degrees. And so on, if the rotating unit rotates 90 degrees, the hand rotating block only needs to rotate 90 degrees.

When the two foot rests need to be folded, referring to fig. 4, only the limit pin 14 needs to be pressed down, the inclined surface of the original limit pin presses the concave cavity of the right support rod under the action of the spring force, the inclined surface of the limit pin is changed into the inclined surface which leaves the concave cavity of the right support rod, so that unlocking is achieved, and at the moment, only the right foot rest needs to be rotated, and folding of the right foot rest can be achieved. The limiting and unlocking principle of the left foot rest is the same as that of the right foot rest.

A bipod frame for rifle, owing to adopted neotype rotatory support 1, can make the muzzle conveniently rotate the position of 8 orientations. Because the novel left and right foot rests are adopted, the two foot rests can be unfolded smoothly from the folded state and can be retracted quickly, the deployment time of the firearm is shortened, and the firearm can enter the shooting state quickly to win the opportunity of battle; meanwhile, the height-adjustable bipod can be used for adjusting the height of a firing line shot by a light machine gun according to the terrain, so that the battlefield terrain adaptability of the firearms is enhanced.

The foregoing is illustrative of the preferred embodiments of the present invention only, and is not to be construed as limiting the claims.
