The invention belongs to the technical field of brake release equipment, and relates to a push-pull type hand pull release device. A stainless steel wire is arranged in a wire core of the push-pull type hand pull release device, a stainless steel strip is spirally wound on the outer side of the wire core, and the wire core has rigidity; the left end of a threaded joint is fixedly connected with an anti-disengaging plate through a nut, and the nut is tightly clamped by the plate surface of the anti-disengaging plate; the right end of a guide pipe is of an arc-shaped structure and can be rotationally locked in the left end of a fixing pipe, the right end of the fixing pipe is connected with a straight wire hose, the other end of the straight wire hose is connected with a connection pipe, and the connection pipe is provided with a bent portion fixedly connected with a second fixing pipe; the wire core is large in rigidity, can bear a large load, is good in corrosion resistance and abrasion resistance and can make a parking pull lever or a parking pin to return to the original position; a certain swing angle is generated when a hand pull release lever mechanism moves, the right end of the guide pipe can rotate and swing by a certain angle around the fixing pipe to adapt to swing of a lever, stress caused by swing and borne by the threaded joint is prevented, and the push-pull type hand pull release device is long in service life and convenient to use.
