Detailed Description
Referring to fig. 1 a-10, an embodiment of a bottom supporting structure of a firearm with adjustable height is disclosed, after a bottom supporting screw 5 is unscrewed by a wrench, the bottom supporting screw can be held by a hand to slide up and down within a certain range, so as to realize the adjustment of the height of a shouldering, and after the bottom supporting screw is adjusted to a proper position, the bottom supporting screw is screwed by the wrench, so that the bottom supporting is fixed. The structure includes: the support base comprises a support base 1, a support base insert, a support base 2, a support base screw 5 and a rectangular support base nut 6.
The bottom support 1 is provided with a mounting hole, and a nut of the bottom support screw 5 is positioned in the mounting hole; the support bottom insert is fixedly connected with the support bottom 1, a support bottom screw through hole 102 is formed in the support bottom insert, a screw rod of the support bottom screw 5 penetrates through the support bottom screw through hole 102, and a vertical guide rail groove 103 is formed in the rear end face of the support bottom insert.
The preceding terminal surface that holds in the palm base 2 is equipped with vertical guide rail 203, guide rail 203 and guide rail groove 103 sliding fit for adjust the height of holding in the palm end 1, the inside of guide rail 203 is equipped with vertical ladder spout, the ladder spout is including the rectangular channel 202 that holds in the palm end inserts dorsad to and hold in the palm end inserts adjacent groove 204 of stepping down, the width that steps down groove 204 is less than the width of rectangular channel 202 forms the tang, sliding fit has support end nut 6 in the rectangular channel 202, forms the circumference location to holding in the palm end nut 6, holds in the palm end screw 5 and passes support end screw via hole 102 and hold in the palm end nut 6 and be connected.
