[0019] The utility model is further described below with reference to the accompanying drawings. In the accompanying drawings, 1 is a front magazine hanger, 2 is a rear magazine hanger, 3 is a threaded hole, 4 is a Q-shaped handle, 5 is a positioning plate, 6 is a steel ball, 7 is a spring, 8 is a positioning pin, 9 is a front positioning groove, 10 is a rear positioning groove, and 11 is a positioning hole.
[0020] See also Figure 1-Figure 5A magazine interface includes a firearm connecting part (a receiver or a magazine seat) and a magazine. The firearm connecting part has a magazine mounting port, a front positioning slot is provided on the front wall of the magazine mounting port, and a rear positioning slot is provided on the rear wall of the magazine mounting port. The front positioning slot is a forward horizontal slot, and the rear positioning slot is an upward vertical slot. A magazine front hanger is provided at the upper front end of the magazine, and the magazine front hanger is inserted into the front positioning slot for positioning. A magazine rear hanger is provided at the upper rear end of the magazine, and the magazine rear hanger is inserted into the rear positioning slot and positioned by a laterally inserted positioning pin. The thickness of the magazine front hanger is less than the thickness of the front positioning slot, and the length of the magazine front hanger is less than the depth of the front positioning slot, so that after the magazine front hanger is inserted into the front positioning slot, the magazine rear hanger can swing to align with the positioning hole. A threaded hole connected to the front positioning slot is provided at the lower end of the front positioning slot, and a flat-end set screw is installed in the threaded hole. The flat-end set screw conflicts with the magazine front hanger, and the flat-end set screw eliminates the gap between the magazine front hanger and the front positioning slot in the vertical direction.
