The invention discloses a multi linear restraint tension measuring device on an engine, including: support rod, cross beam, steering seat, scale ruler, pulley one, longitudinal bar frame, pulley two, pulley three, steel cable, pull rod head, longitudinal bar frame with L shape, grooves at right angle of longitudinal bar frame, and steel cables passing through the pulley two in the grooves; longitudinal bar frame, The pulley is provided with a hole through which the steel cable is worn; the end of the longitudinal bar is welded with a steering seat; the groove on the upper part of the longitudinal bar is equipped with a pulley three for the steel cable; a beam is welded on the longitudinal bar, and the two ends of the beam are welded separately; there is a pulley through the steel cable in the upper groove of the steering seat, and a measuring steel cable is set at the bottom. The end of the steel cable is fixedly provided with a pull rod head, and the front end of the steel cable is connected with the tension meter after passing the scale. The device of the invention makes the measuring process more stable. Even if the tightening force increases, the device will not be skewed. Add a number of fixed pulleys to solve the limitation of measurement space, change the direction of force and shorten the distance of movement.
