Safety hammer with pre-strike

Abstract

The invention relates to a safety hammer with a pre-striking member, comprising a hammer head, a handle and the pre-striking member, wherein a conical first sharp part is arranged at the lower part of the hammer head; the handle is movably connected with the hammer head through a connecting rod, a first groove is formed in the handle in the position close to the lower side, a pivot is arranged on the handle in the position close to the upper part, a connecting base is arranged at one end, articulated with the handle, of the connecting rod, a shaft hole is formed in the connecting base, and the pivot passes through the shaft hole so as to enable the connecting rod and the handle to be pivoted; and the pre-striking member comprises a pre-striking member body and a conical second sharp part arranged at one end of the pre-striking member body, and the length of the pre-striking member is 1.5-2cm greater than the length of the first groove of the handle, so that the pre-striking member body can be placed in the first groove in a set time period, and the pre-striking member body can slide along the first groove under the action of external force so as to extend out of the first groove to carry out striking operation. The safety hammer with the pre-striking member, provided by the invention, is simple in structure, strong in striking force, and suitable for a user with relatively small force.

Description

technical field [0001] The invention relates to a safety hammer. More specifically, the present invention relates to a safety hammer having a pre-strike. Background technique [0002] Safety hammer, also called life-saving hammer, is an auxiliary escape tool in a closed cabin, which is generally installed in a car. When the car is on fire or falls into the water and other emergency situations, the glass doors and windows can be smashed for escape. The safety hammer mainly uses the conical tip of the hammer head. The contact area between the tip of the hammer head and the glass is very small. When the safety hammer is used to smash the glass, the pressure of the tip of the hammer head on the glass is relatively large, which can smash the glass . But the impact force of this safety hammer depends entirely on the strength of the user itself. When the user is a woman, the elderly, a child or an injured person with less strength, they may not have enough strength to use the ex...
