Detailed description of the invention
Be described in detail the utility model below in conjunction with view, the following examples can make professional and technical personnel more understand the utility model, but do not limit the utility model in any form.
As shown in figs. 3-9, a kind of folding tommy gun gun stock, comprise wooden gun stock 1, tailstock 2, casing body 3, tailstock 2 adopts rivet to be combined with casing body 3, gun stock seat 4 is connected with between wooden gun stock 1 and tailstock 2, gun stock seat 4 and wooden gun stock 1 fix with two wood screws, and joint adopts slight interference fit, increases fastness.Connection between gun stock seat 4 and tailstock 2 is the ratchet of self-locking to connect.Gun stock seat is connected with tailstock bearing pin 5, fixing on gun stock seat, can not in use deviate from two of pin by rushing rivet clasp.Connection between gun stock seat 4 and tailstock 2 is for having two status lock locking structures, stretch for holder for one, one is folding, specifically, gun stock seat 4 has gun stock seat axis hole 41, tailstock 2 is also drilled with the tailstock axis hole 21 matched, gun stock seat axis hole 41 is identical with tailstock axis hole 21 size, short transverse be interval be fitted together to, gun stock seat is connected with tailstock with tailstock axis hole 21 through gun stock seat axis hole 41 by bearing pin 5, the cross section of gun stock seat 4 has the button post holes 42 paralleled with gun stock seat axis hole 41, button post 6 is installed in button post holes 42, the middle part of button post 6 is processed with holder and stretches locking inclined-plane 61, the end that locking inclined-plane is stretched in holder has locking slot 62, tailstock 2 has to stretch with holder and lock the tailstock holder matched on inclined-plane 61 and stretch and lock inclined-plane 22, and locking bail 23 is stretched in the holder to match with locking slot 62, folding locking inclined-plane 63 is processed with at the end of button post 6, the end on folding locking inclined-plane 63 has folding locking groove 64, tailstock 2 there is the tailstock folding locking inclined-plane 24 matched with folding locking inclined-plane 63, and the folding locking hook 25 to match with folding locking groove 64, button post 6 is built with return spring 7, the bottom of gun stock seat 4 has the pin-and-hole 43 matched with straight pin 8, pin-and-hole 43 is through hole, button post 6 axially has the elongated hole 65 matched with straight pin 8, straight pin 8 is through pin-and-hole 42 and elongated hole 65, button post 6 is connected with gun stock seat 4.
The design designs for left folding, stretches locking inclined-plane, tailstock holder stretches locking inclined-plane, folding locking inclined-plane, tailstock folding locking bevel direction on the contrary to holder in right folding figure.
