Countersunk bolt and nut detaching tool

A countersunk bolt and nut detaching tool is used for solving the problem that slotted countersunk nuts and slotted countersunk bolts are difficult to detach. The countersunk bolt and nut detaching tool comprises a clamping seat, a nut clamping detaching component and a bolt clamping detaching component. The clamping seat is of a frame structure with one side open and is assembled with the nut clamping detaching component through a first threaded hole in the outer side face of the clamping seat, and the clamping seat is assembled with the bolt clamping detaching component through a second threaded hole in the inner side face of the clamping seat. The nut clamping detaching component is matched with a slotted countersunk nut to be detached, and the bolt clamping detaching component is matched with a slotted countersunk bolt to be detached. The countersunk bolt and nut detaching tool has the advantages of being simple in structure, convenient to operate, and capable of improving work efficiency, avoiding damaging slotted countersunk nuts and slotted countersunk bolts, and reducing maintenance cost of mechanical devices.
