Adaptive multifunctional wrench

Abstract

This application relates to the field of repair tool technology, and more particularly to an adaptive multi-functional wrench, which includes a main rod, a telescopic rod, and a wrench replacement head. The main rod has a through groove along its length with its opening located at one end. The telescopic rod slides through the through groove, with its sidewall slidably conforming to the inner wall of the groove. A first locking component is provided between the main rod and the telescopic rod for locking the telescopic rod. The wrench replacement head includes an operating part and a connecting part, which are integrally formed. The operating part has an opening adapted to fit a nut. Two locking blocks are fixedly connected to the connecting part. The main rod has a slot for the locking blocks to engage, and a second locking component is provided on the main rod for locking the locking blocks. This application improves upon the problems of large carrying capacity and low operating efficiency of repair tools, enabling the wrench tool to quickly detach and assemble its head and adaptively match different nut sizes.
