Summary:The utility model discloses a pre-force-applied type lifesaving hammer which comprises a hammer shell with one end open. A hammer shaft is connected into the hammer shell through an elastic part I, a hammer head capable of crushing objects is mounted on the end face of the hammer shaft, and a groove is formed in one side of the hammer shaft; a locking switch device matched with the groove in the hammer shaft for controlling knocking is mounted on one side of the hammer shell. The pre-force-applied type lifesaving hammer overcomes the defect that the old, children and other people who have weak strength cannot crush glass through a conventional lifesaving hammer, and the hammer can be repeatedly used, can be used next time through a matched tool after the hammer is used, and is simple in structure, easy to operate and convenient to use.
