The invention discloses a brake clutch device of a lever block. The brake clutch device comprises a brake base arranged on a long shaft of the lever block, a brake ratchet, an inverting ratchet, a torsion spring base, a handwheel and a fixed part, wherein the brake base and the long shaft are circumferentially fixed; two sides of the brake ratchets are respectively provided with friction plates; the inverting ratchet is in threaded connection with the long shaft; the torsion spring base and the inverting ratchet are circumferentially fixed; the long shaft between the torsion spring base and the handwheel is sleeved by a torsion spring; a spring steel ball is arranged between the torsion spring base and the handwheel; the end surface of the torsion spring base is provided with a concave part capable of accommodating the spring steel ball; the handwheel and the long shaft are circumferentially fixed; the surface of the handwheel is provided with indication points for indicating relative position changes of the handwheel and the torsion spring base; the end surface of the torsion spring base is provided with an indication region for displaying the position changes of the indication points. The brake clutch device has the advantage that the abrasion states of the friction plates can be directly observed without detaching the lever block, so that the friction plate can be replaced in time.
