Wrench for limited space

The utility model discloses a wrench for limited space, which comprises a base, an inner square shaft, a shaft rod and a transmission component, the inner square shaft downwards penetrates through the base and is rotatably connected with the base, the bottom surface of the inner square shaft is inwards sunken to form a polygonal accommodating cavity, the shaft rod horizontally penetrates through the base and is rotatably connected with the base, and when the shaft rod is driven by external force to rotate, the transmission component is driven by the shaft rod to rotate. The shaft rod transmits rotation motion to the inner square shaft through the transmission assembly so as to drive an object in the polygon containing cavity to rotate. The utility model has a reasonable structure, can be quickly disassembled and assembled in a narrow space, and is beneficial to popularization and application. 本实用新型公开了一种受限空间用扳手，包括底座、内方轴、轴杆和传动组件，所述内方轴向下穿经底座且与底座转动连接，所述内方轴的底面向内凹陷形成多边体状容置腔，所述轴杆水平穿经底座且与底座转动连接，当外力驱动轴杆旋转时，所述轴杆通过传动组件将
