[0128] It should be noted that the angle between the cutting edge of the cutting piece 410 and the inner wall of the protective piece 134 is 15° to 20°; preferably, the angle between the cutting edge of the cutting piece 410 and the inner wall of the protective piece 134 is 17°; that is, when using the cutting piece 410 for cutting, the resistance between the object to be cut and the cutting edge of the cutting piece 410 along the cutting direction is small, which is more labor-saving to use.

[0129] It should be noted that the maximum vertical distance from the cutting edge of the cutting piece 410 to the protective piece 134 is 3 to 5 mm. When the cutting piece 410 of the vehicle-mounted multifunctional window breaker is used to cut the seat belt, the distance from the cutting edge of the cutting piece 410 to the protective piece 134 is too large, and the fingers are easily scratched by the cutting edge. The distance from the cutting edge of the cutting piece 410 to the protective piece 134 is too small, especially in an emergency, the seat belt is not easy to pass through the opening for cutting; preferably, the maximum vertical distance from the cutting edge of the cutting piece 410 to the protective piece 134 is 5 mm, that is, it is easy to put the seat belt between the protective piece 134 and the cutting piece 410, and it will not be scratched when the cutting piece 410 is not in use.

[0130] It should be noted that the inner wall of the protective member 134 abuts against one end of the cutting member 410 close to the upper portion of the first shell 110 , and when the cutting member 410 is used, the situation where the cutting member 410 becomes loose due to excessive force can be reduced.

[0131] The method of using this embodiment is as follows:

[0132] In a non-emergency situation, the driver or passenger can insert the bottom of the first housing 110 into the vehicle port of the vehicle, and the connection terminal 313 at the bottom of the first housing 110 can be docked with the vehicle port, and the abutment member 312 on the side wall of the first housing 110 can be tightly abutted with the side wall of the vehicle port, so as to realize the clamping connection between the bottom of the first housing 110 and the vehicle port;

[0133] Afterwards, the driver or passenger can connect the electronic device to the corresponding charging port 322 through a connection line device such as a data cable, thereby realizing the transfer of the vehicle port, and then the electronic device can be connected to the charging port 322 to realize the charging of the electronic device;

[0134] In an emergency, the driver or passenger can take out the second housing 120 from the vehicle port and chisel the second housing 120 toward the vehicle window, and by pressing down the second housing 220, the window-breaking member 240 located inside the first housing 210 and the second housing 220 extends out of the second housing 220, so that the window-breaking member 240 breaks the vehicle window;

[0135] Then, the driver or passenger inserts the seat belt between the interior of the protective member 134 and the outer wall of the first shell 110, and slides the vehicle-mounted multifunctional window breaker to loosen the seat belt that restrains the driver or passenger, making it easier for the driver or passenger to climb out of the vehicle through the window.

[0136] The advantage of this embodiment is that by combining the charging component, the window breaking component and the cutting component, in non-emergency situations, the driver or passenger can insert the vehicle-mounted multifunctional window breaker into the vehicle-mounted port, so that the vehicle-mounted multifunctional window breaker can be used as a cigarette lighter adapter; in emergency situations, the driver or passenger can directly take out the vehicle-mounted multifunctional window breaker from the vehicle-mounted port and break the window, which is convenient to use and can be quickly taken out in an emergency; in addition, the driver or passenger embeds the seat belt between the inside of the protective component and the outer wall of the first shell, and slides the vehicle-mounted multifunctional window breaker, thereby loosening the seat belt that restrains the driver or passenger, making it easier for the driver or passenger to climb out of the vehicle through the window.

[0137] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0138] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
