Glass hammer

Abstract

The invention discloses a glass hammer, comprising a handle, a spring, a guide rod, a hammer body, a control block, a base, a lock bolt and a punch. The control block is arranged in the hammer body slidably along the axial direction of the hammer body; one end of the guide rod is connected with the handle and the other end of the guide rod extends into the hammer body to be connected with the control block; the spring sleeves the position, between the handle and the hammer body, of the guide rod; the punch is movably arranged in the base; the base is provided with an impact hole correspondingto the punch; the lock bolt for limiting the control block is arranged in the base; the end, provided with the control block, of the hammer body is arranged in the base. Rated adjustable potential energy is stored in an energy storage element, and can be released to the punch in a specific state, the punch applies the potential energy to glass instantly to generate a high stress to glass locally,and then the glass is broken along with expansion of cracks. The glass hammer is small in size, easy to operate, and capable of breaking vehicle window glass rapidly.

Description

technical field [0001] The invention relates to the technical field of devices for crushing glass, in particular to a device for crushing glass. Background technique [0002] When a person is trapped in the car and needs to escape due to the vehicle falling into the water, unlocking failure, etc., the biggest possibility is to break the vehicle glass and escape from the window position. However, the car glass is strengthened, so it is difficult to escape in an emergency. Time-saving and labor-saving crushing, and there is not enough room for manipulation when using blunt instruments such as hammers when the vehicle is deformed. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the technical problem to be solved by the present invention is to provide a device for crushing glass to achieve the purpose of small size and rapid glass crushing. [0004] In order to solve the problems of the technologies described above, the technical solution adopt...
