[0029] The present invention will be further described below with reference to embodiments: Figures 1 to 11 This is a schematic diagram of an embodiment of the present invention. In the figure, a steel strip roll-type single-leg shotgun mount includes a housing (1), a pair of parallel steel strip rolls (2), a steel strip clamping assembly, a manual steel strip locking assembly, a stabilizer (5), and a base assembly (6), wherein:

[0030] The steel strip roll (2) consists of a drum and a shaft (21), a spiral spring, and a steel strip (22). The shaft (21) has a blind hole (23) at its end. The spiral spring has an arc-shaped unfolded cross section, and the steel strip (22) extends out of the steel strip roll (2) in an arc shape. The free end of the steel strip (22) has a fixing hole (24) fixed to the base body (62). One end of the spiral spring is fixed to the shaft (21), and the other end is fixed to the steel strip (22). The steel strip (22) is wound into the drum by the spiral spring, and the free end of the steel strip (22) extends out of the drum. The structure of the steel strip roll in this structure is as follows: Figure 2 As shown, the elongation and contraction of the steel strip are accomplished by a spiral spring.

[0031] The steel strip clamping assembly consists of a button (31), a button pin pressure plate (34), a clamp, and a leaf spring (33). The button (31) includes an intermediate body (311), a button head (312) fixed to the back of the intermediate body, a pin (313) fixed to the lower end of the intermediate body, a forked arm (314) fixed to the front of the intermediate body at a certain distance, and an angle plate (315) at the end of the forked arm. Figure 3 As shown. The clamp consists of a pair of fixed clamps (30) and a pair of movable clamps (32). The protruding front end of the movable clamp (32) is the same as the arc shape of the steel strip (22). The two sides of the fixed clamp (30) match the arc of the movable clamp (32) that they are in contact with. The gap between the pair of fixed clamps (30) and the pair of movable clamps (32) forms the space for clamping the pair of steel strips (22). Figure 5 As shown, the back side of the movable clamp (32) is provided with a strip groove (321) for accommodating the leaf spring (33) and pins (322) distributed on both sides of the strip groove, as shown. Figure 4As shown, the pair of fixed clamps (30) are fixed to the outer shell, and the pair of movable clamps are located below the forked arm (314) of the steel strip clamping assembly. The corner plate (315) of the forked arm (314) contacts the upper surface of the protruding front end of the movable clamp (32). The leaf spring (33) is located in the strip groove (321) on the back side of the movable clamp (32). Under the pressure of the leaf spring (33), the protruding front ends of the two movable clamps (32) contact each other, and the distance between the protruding front ends of the two movable clamps above the contact point gradually increases. In this structure, after installation, the steel strip of the steel strip roll is clamped between the fixed clamp and the movable clamp of the clamp. When it is necessary to release the clamp, the button is pressed by hand, and the forked arm of the button rotates around the central pivot at the same time. The corner plate of the forked arm presses down the movable clamp, and the movable clamp rotates around its own pivot. The gap between the fixed clamp and the movable clamp increases, releasing the constraint on the steel strip of the steel strip roll. The steel strip can be quickly retracted into the steel strip roll drum by the elastic force of the steel strip roll spiral spring. If the button is released, the movable clamp returns to its original position under the action of the back leaf spring, and the movable clamp once again holds the steel strip between the movable clamp and the fixed clamp. The clamping force of the movable clamp and the fixed clamp holding the steel strip is greater than the elastic force of the steel strip coil spring, which can ensure that the steel strip stays in any position.

[0032] The manual steel strip locking assembly includes a steel strip locking block (41) and a manual locking turntable (42). The steel strip locking block has an upper panel (45) and a lower panel (46). The outer edges of the upper and lower panels are composed of a symmetrical inner bend line in the middle and arc lines on both sides that connect with the bend line. The interior of the upper and lower panels has two symmetrical and intersecting arc-shaped slots (47) for inserting a pair of steel strips. The lower panel has two sets of locking tongues on the arc section of the arc-shaped slots through vertical ribs. One set of locking tongues is a convex arc surface (48), and the other set of locking tongues is a double concave arc surface (49). The double concave arc surface matches the two adjacent convex arc surfaces. The back of the convex arc surface locking tongue and the double concave arc surface locking tongue are provided with horizontal ribs (481) and (491). The end faces of the free ends of the horizontal ribs (481) and (491) are on the same circumference. Figure 6 , Figure 7 As shown, the manual locking turntable (42) is in the shape of a boss. The upper end of the inner cavity of the boss is provided with four arc-shaped areas (44) corresponding to the free ends of the horizontal ribs of the steel strip locking block. The outer edge of the boss of the manual locking turntable (42) is provided with a pair of flat flanges (43) that can be inserted into the groove at the bottom of the inner cavity of the outer shell. Figure 8 , Figure 9 As shown in the diagram, in this structure, the steel strip locking block and the manual locking turntable are installed in the corresponding grooves of the outer shell. The steel strip locking block is embedded into the corresponding grooves of the outer shell by the shape of the outer edges of the upper and lower panels, and its position remains fixed. The pair of flat flanges of the manual locking turntable can rotate in the corresponding grooves of the outer shell. When rotating, the four arc-shaped areas at the upper end of the inner cavity press against the horizontal ribs on the back of the convex arc-shaped locking tongue and the double concave arc-shaped locking tongue of the steel strip locking block, tightening the gap between the arc surfaces of the convex arc-shaped locking tongue and the double concave arc-shaped locking tongue, clamping the steel strip of the steel strip coil, and playing a role in locking and positioning.

[0033] The upper end of the outer shell (1) is V-shaped and is divided into two parts that can be connected by screws along the middle plane of the V-shape. The inner cavity of each part is provided with: a protrusion for fixing the blind hole (23) of the steel strip roll (2), a groove for fixing the clamp (30) of the clamp, a bearing seat for rotating the pins (322) on both sides of the movable clamp (32) of the clamp, an insertion port for fixing the two ends of the leaf spring (33), a groove for inserting the outer edges of the upper and lower panels (45) and (46) of the steel strip locking block (41), a groove for inserting a pair of flat flanges (43) of the manual locking turntable (42), a cavity for inserting the button head (312) of the steel strip clamping assembly button (31) into one of the split outer shells, a bearing seat for rotating the pin (313) at the lower end of the middle body of the button, and a screw hole for fixing the button pin pressure plate (34). In this structure, the outer shell provides the definite positions of the components of the steel strip coil, the steel strip clamping assembly, and the manual steel strip locking assembly.

[0034] The stabilizer (5) is in the shape of a boss, the outer edge of which matches the inner cavity of the manual locking turntable (42). The upper surface of the boss has two symmetrical and intersecting arc-shaped slots (52) for inserting a pair of steel strips (22). The edges of the arc-shaped slots (52) have several flanges (53). Figure 10 As shown in the diagram, in this structure, a pair of steel strips are clamped together by several flanges to keep the stabilizer in a given position. Since the steel strips in the roll, when pulled out and elongated, become slender rods under compression, one characteristic of slender rods is their susceptibility to instability, making them unsuitable as stable supports for the firearm. The use of a stabilizer eliminates this possibility.

[0035] The base assembly (6) consists of a fixing wedge (61) and a body (62). The body (62) is a boss-type structure with a split, screw-connectable design. The inner cavity of the boss has a protrusion (63) that is identical in shape to the arc of the steel strip. Bolt holes for fixing the steel strip (22) are provided at the protrusion (63). The fixing wedge (61) is fan-shaped. Figure 12 As shown, the concave arcs on both sides of the fan shape match the arc shape of the protrusion. The small end of the fan shape has an opening hole (64) for the fixing steel strip bolt to pass through. The two split structure protrusions are fixed together by bolts. The fixing wedge (61) is inserted into the space left by the two protrusions (63). There is a gap between the two protrusions (63) and the two fixing wedges (61) for a pair of steel strips (22) to be inserted. Figure 11 As shown.

[0036] The blind hole (23) of the steel strip roll (2) is embedded in the protrusion of the outer shell (1). The pin (313) at the lower end of the middle body (311) of the button (31) is embedded in the shaft seat of the outer shell. The pin pressure plate (34) is fixed to the outer shell (1) by screws to form a rotating seat for the button to rotate. The button head (312) of the button (31) is located in the cavity of the outer shell (1). The fixing clamp (30) is located in the corresponding groove of the outer shell. The pin (322) of the movable clamp (32) is embedded in the corresponding shaft seat of the outer shell (1). The leaf spring (33) is inserted into the corresponding socket of the outer shell (1). The outer edges of the upper and lower panels of the steel strip locking block (41) are embedded in the corresponding groove of the outer shell (1). The flat flange (43) of the manual locking turntable (42) is embedded in the outer shell. (1) In the corresponding groove, the end faces of the free ends of the horizontal ribs (481) and (491) of the two sets of locking tongues of the steel strip locking block (41) are located in the four arc-segment areas (44) of the inner cavity of the manual locking turntable (42). A pair of steel strips (22) pass through the gap between the fixed clamp (30) and the movable clamp (32) and pass through the arc gap between the convex arc surface (48) and the double concave arc surface (49) of the two sets of locking tongues of the steel strip locking block (41). The free ends of the pair of steel strips (22) extend out of the outer shell (1), pass through the two symmetrical and intersecting arc-shaped slots of the stabilizer (5), and finally insert into the gap between the two protrusions (63) and the fixed wedge (61) of the base body (62). The pair of steel strips (22) are fixed on the base body (62) by bolts (69). In this structure, since the main body of the manual locking turntable, stabilizer, and base assembly are all boss-type structures, they can all be inserted into adjacent components. After tightening, the overall size can be greatly reduced, which is conducive to easy carrying.

[0037] The present invention further includes the following measures: a dust scraper (40) is provided between the upper panel (45) and the lower panel (46) of the steel strip locking block, and the dust scraper (40) has a gap for inserting a pair of steel strips (22). The dust scraper is usually made of rubber or polyethylene foam, and the dust on the steel strip can be scraped off when the steel strip passes through the dust scraper.

[0038] The curvature centers of the four arc segments (44) within the inner cavity of the manual locking turntable are offset from the axis of the inner cavity, and the distance from each point on the arc segment (44) to the axis of the inner cavity gradually decreases. The steel strip locking block in this invention is inserted into the groove of the outer shell and remains fixed. The locking tongue of the steel strip locking block is tightened and clamped by rotating the manual locking turntable. In this structure, the manual locking turntable only needs to rotate a small angle (less than 90 degrees) to clamp or loosen the locking tongue.

[0039] The base assembly includes a disassembly plate rod (68), which is arc-shaped. A protruding block (67) is located on the outer edge of one end of the arc-shaped rod. The base of the protrusion on the body (62) of the base assembly has an annular opening groove for the disassembly plate rod (68) to be inserted. The arc-shaped rod is hinged within the annular opening groove of the boss on the body (62) of the base assembly. The protruding block (67) of the arc-shaped rod protrudes outside the base of the boss on the body (62). The base assembly includes a support sleeve, the base of which is elliptical.

[0040] The embodiments of the present invention have been described above with reference to the accompanying drawings and examples. The structures given in the embodiments do not constitute a limitation on the present invention. Those skilled in the art can make adjustments according to actual needs. Various modifications or variations made within the scope of the appended claims are within the scope of protection.
