The invention discloses a manual tensioning device, relates to the field of traction structures, and adopts the technical scheme that the manual tensioning device comprises a worm, a worm gear, a locking control mechanism, an outer cylinder body and an inner cylinder body; the worm and the worm gear are in running fit, the worm gear and the hollow screw rod are in running fit, the hollow screw rod can push the inner cylinder body to axially slide in the outer cylinder body, and the locking control mechanism can manually lock or unlock the locking device; an inner cavity of the inner cylinder body is in sliding fit with an inner piston, the inner piston is connected with a pull rod, and the pull rod extends out of the outer cylinder body; and a pre-pressing spring is arranged between the inner piston and the front end of the inner cylinder body. By means of the manual tensioning device, the pull rod can be manually made to output tensioning force outwards, and then the inner cylinder body is unlocked or locked through the locking control mechanism. If the device is applied to anti-slip stopping of railway vehicles, enough, stable and lasting braking force can be generated for the vehicles in a manual mode.
