Abstract:
A sewing-free dragging/stretching snap hook, comprising a hardware snap hook (1) and a webbing device (3). The webbing device (3) is provided with a rectangular frame; the lower end of the hardware snap hook (1) is rotatably connected to the rectangular frame of the webbing device (3); the webbing device (3) further comprises a pressing fastener (5); the pressing fastener (5) is located inside the rectangular frame and is rotatably connected to the rectangular frame by means of a pin (6); the pressing fastener (5) comprises a plate, a pressing fastener tail end (10), and pressing fastener front end teeth (9); a spring (7) is sleeved on the pin (6); a spring force bearing crossbar (11) is fixed inside the rectangular frame; the spring force bearing crossbar (11) is located above the spring (7). The present invention can be manually assembled without the help of a tool when there is no device, and can be used repeatedly; a movable crossbar is slid by hand to push against the pressing fastener, then webbing is enabled to pass through the webbing device, the length of the webbing to be pressed can be adjusted at will, and the fingers can be prevented from being exhausted due to pressing a pressing sheet by hand for a long time; after resetting the movable crossbar, the pressing fastener can press the webbing; thus, repeated use of a retractable dog (drag) rope or repeated use of other products that require stretching by a snap hook is implemented.
