It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0026] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0027] like Figure 1-4As shown, a quick-release mechanism for a firearm accessory comprises a mounting seat 1 that can be mounted on a firearm, a plurality of positioning mechanisms 2, a movable seat 3 that can be mounted on the firearm accessory, and a clamping mechanism. The mounting seat 1 is in the shape of an elongated strip, a plurality of positioning mechanisms 2 are fixedly arranged on one side of the mounting seat 1, and are evenly distributed along the length direction of the mounting seat 1, the positioning mechanism 2 comprises a guide member 21, a slide seat 22, and a third spring 23, the guide member 21 is vertically arranged on the mounting seat 1, the slide seat 22 is slidably connected to the guide member 21, the third spring 23 is used to drive the slide seat 22 to slide in a direction away from the mounting seat 1, the movable seat 3 can squeeze any one of the three adjacent slide seats 22 located in the middle, so that the slide seat 22 slides along the guide member 21 toward the mounting seat 1, and when the movable seat 3 is slidably connected thereto When the movable seat 3 is between the remaining two slides 22, the clamping mechanism can connect the movable seat 3 and the remaining two slides 22, so that the movable seat 3 is fixed between the remaining two slides 22. When disassembling the firearm accessories, it is only necessary to release the connection between the movable seat 3 and the remaining two slides 22, so that the movable seat 3 can be pulled out from between the slides 22. At this time, the squeezed slide 22 will slide up and reset under the energy release action of the third spring 23. The user can adjust the installation position of the firearm accessories by selecting the movable seat 3 to squeeze the slide 22 in different positions, and use the clamping mechanism to quickly connect or separate the firearm accessories and the firearm, avoiding the installation and disassembly method of moving the firearm accessories back and forth, reducing the obstacles of the environment and other firearm accessories to the installation and disassembly of the firearm accessories, and improving the convenience of operation.

[0028] Specifically, the guide member 21 can be a slide rail, which is vertically arranged on one side of the mounting seat 1, and the slide seat 22 is slidably connected to the slide rail (not shown in the drawings).

[0029] In one embodiment, the clamping structure may include two locking tongues, which are symmetrically slidably connected to the front and rear sides of the movable seat 3 and can be extended out of the movable seat 3 by spring drive. A lever is connected to one side of the locking tongue, which penetrates the movable seat 3 to the outside. Locking grooves are symmetrically provided on the front and rear sides of the slide 22. When in use, the user can drive the locking tongue to slide back into the movable seat 3 by the lever, and make the movable seat 3 squeeze the middle one of any three adjacent slides 22, so that the movable seat 3 is slidably connected between the remaining two slides 22, and then release the control of the lever. At this time, the locking tongue will be extended and clamped with the locking groove under the drive of the spring, thereby fixing the movable seat 3 between the remaining two slides 22 (not shown in the drawings).

[0030] Furthermore, the clamping mechanism includes a first clamping member 4, which includes a first clamping block 41 and a first spring 42.
