A tempered glass breaker as claimed in claim 1, wherein, The lower outer guide tube (112) includes a plurality of guide plates (112 a, 112 b) arranged in a circular arc shape at predetermined intervals, and a plurality of form retaining plates (115) arranged between adjacent guide plates (112 a, 112 b) and formed to have a height higher than the guide plates (112 a, 112 b) so as to be detachably coupled from the support plate (111) when the striking part (120) descends.
3. 3. A tempered glass breaker as claimed in claim 1, wherein, A lower hook (113 a) and an upper hook (122 c) are arranged at the upper end of the crushing tip guide tube (113) and the lower end of the tip fixing shaft (122), and the lower hook (113 a) and the upper hook (122 c) are formed in corresponding shapes so as to be mutually engaged to guide the tip fixing shaft (122) to descend.
4. 4. The tempered glass breaker of claim 1, further comprising: And a marking part (130) detachably combined with the upper surface of the upper shell (121).

Description

Glass breaking device Technical Field The present invention relates to a tempered glass breaker, and more particularly, to a flat tempered glass breaker for breaking tempered glass in an emergency situation such as an automobile or a building. Background In the case that a fire disaster occurs in an automobile such as a highway, a general road, etc., and the automobile cannot be evacuated to the outside, serious casualties may occur. In particular, not only in korea but also worldwide, there is an increasing trend in property and casualties caused by bus fires, and government-proposed emergency exits and fire extinguisher-related amendments have led to over 1,000 pieces in five years. However, despite these measures taken by governments, the number of incidents has seen a dramatic trend each year. In most of these accidents, the cause of death is choking death, and in the case of fire, escape is delayed because it is difficult for smoke to ensure visibility of the field of view, and in most cases, choking occurs due to narrowing of the airway by inhaling smoke only once. In addition to fire, in the case of a vehicle falling into water, water enters the inside of the vehicle to cause a pressure difference between the inside and the outside of the vehicle, and thus the door cannot be easily opened, resulting in a long time taken for escape from the vehicle, and thus a problem of extremely decreasing survival rate also occurs. Most of glass windows equipped in automobiles are toughened glass, the strength of the toughened glass is 4-5 times that of common glass, and the toughened glass is special glass subjected to high heat treatment, so the toughened glass is not easy to break. Recently, double glazing increasingly used to secure a quiet indoor space is more difficult to break. The most common escape safety device on buses is the safety hammer. However, in an emergency situation, a rescuer must find a safety hammer in person to break glass, so that the use rate is very low, and most of the cases are bound in a car or lost to prevent theft, so that the glass cannot be used in an actual situation. For example, when a fire disaster occurs in a bus, the generated smoke causes difficulty in finding a safety hammer, and even if the safety hammer is found, the window of the bus made of toughened glass cannot be broken rapidly, so that the escape time is delayed, and therefore, more casualties are often reported as the escape time is delayed. In particular, unlike foreign countries, buses on expressways without intermediate doors in korea are more difficult to escape in the event of fire, and even in the case of electric vehicles whose popular number is recently increasing, there are frequent cases where the doors cannot be opened due to battery discharge, the vehicles die due to fire, or citizens who are passing by because the doors cannot be opened in roof parking cars in summer are caused to rescue the vehicles. Accordingly, a glass breaking device that can easily break tempered glass is recently provided in an automobile instead of a safety hammer. Recently, a glass breaking device equipped in an automobile is disclosed in korean laid-open patent No. 10-2020-0144433. As disclosed in this patent publication, in the conventional glass breaking device, a breaking portion having hardness is located inside a housing in a state of being compressed by a compression spring, and if a user releases the fixing force of the compression spring, the breaking portion breaks tempered glass by the elastic force of the compression spring. However, such a conventional glass breaking device using the elastic force of the compression spring frequently fails to operate properly due to the failure of the compression spring, and has a shape having a long height in the upper and lower directions because the compression spring needs to be housed therein, and when attached to a glass window, it has drawbacks in that it affects the beauty or it has inconvenience of restricting the passage of users, and it is not possible to maintain uniform quality depending on the quality of the spring, the frequency of use and the storage environment, and therefore, it has drawbacks as a glass breaking device that should always maintain an optimal state. In addition, most of breaking tips installed in commercially available glass breaking hammers use low-cost plastic or metal heat-treated products, and glass can be broken only by striking specific portions such as corners of the glass, thus reducing the effectiveness, and manufacturers of related products generally do not use high-hardness breaking tips, which can easily break the glass, as materials for reasons of low cost and marketability. Disclosure of Invention (Problems to be solved) In order to solve the above-described problems, an object of the present invention is to provide a tempered glass breaker which is formed in a flat plate shape having a low height and can be attached to a glass window
