It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0026] like Figures 1 to 4As shown, the embodiment of the present application provides a vehicle window glass breaker, including a breaker needle 10, a limit block 20, a movable head 30, a compression spring 11 and a fixed shell 40, wherein the fixed shell 40 is penetrated with a receiving cavity 41 along the axial direction, the movable head 30 is a tubular structure, the front end of the movable head 30 is provided with a first limit hole 31, the movable head 30 is provided with a notch groove 32 along the axial direction, one end of the movable head 30 is movably sleeved in the receiving cavity 41, and the other end extends out of the receiving cavity 41, the rear end of the receiving cavity 41 is provided with a rear end cover 42, the rear end cover 42 is penetrated with a through hole 43, the inner wall of the receiving cavity 41 is provided with an elastic sheet 45, and the breaker The front end of the needle 10 is fixed with a limiting block 20 and the needle head of the punching needle 10 extends out of the limiting block 20. The rear end of the punching needle 10 is movably arranged in the through hole 43. The punching needle 10 is tilted in the accommodating chamber 41. The compression spring 11 is sleeved outside the punching needle 10. The compression spring 11 is located between the limiting block 20 and the rear end cover 42. The edge of the limiting block 20 is clamped in the notch groove 32. When the movable head 30 is pushed to move into the accommodating chamber 41, the elastic sheet 45 contacts the outer wall of the movable head 30 and causes the limiting block 20 to disengage from the notch groove 32. The front end of the punching needle 10 punches out of the first limiting hole 31 under the action of the compression spring 11.
[0027] like Figures 1 to 11 As shown, the compression spring 11 is in a compressed state. When the punching needle 10 needs to break the window glass outward, the movable head 30 is pushed so that the movable head 30 moves into the accommodating chamber 41. When the movable head 30 contacts the elastic sheet 45, the elastic sheet 45 pushes the movable head 30 so that the limit block 20 is separated from the notch groove 32. At this time, the punching needle 10 quickly rushes out of the first limit hole 31 under the action of the compression spring 11, and the front end of the punching needle 10 is used to break the window glass; after use, the movable head 30 is pushed so that the movable head 30 moves out of the accommodating chamber 41, and the movable head 30 is separated from the elastic sheet 45. The punching needle 10 is tilted in the accommodating chamber 41, and the front end of the punching needle 10 is close to the notch groove 32. Then, the edge of the limit block 20 is stuck in the notch groove 32 again, and it can be used again next time. The aperture of the first limit hole 31 is smaller than the outer diameter of the limit block 20, and the front end of the punching needle 10 can move in the first limit hole 31.

[0029] like Figures 3 to 7As shown, when the punching needle 10 needs to break through the car window glass outward, the movable head 30 is pushed so that the movable head 30 moves into the accommodating chamber 41, and the first return spring 12 is in a compressed state. When the movable head 30 contacts the elastic sheet 45, the elastic sheet 45 pushes the movable head 30 so that the limit block 20 is separated from the notch groove 32. At this time, the punching needle 10 quickly rushes out of the first limit hole 31 under the action of the compression spring 11, and the front end of the punching needle 10 is used to break the car window glass; after use, the movable head 30 is released, and the movable head 30 moves out of the accommodating chamber 41 under the action of the first return spring 12, and the movable head 30 is separated from the elastic sheet 45. Since the punching needle 10 is tiltedly arranged in the accommodating chamber 41, the front end of the punching needle 10 is close to one side of the notch groove 32, and then the edge of the limit block 20 is stuck in the notch groove 32 again, and it can be used again next time.
[0030] like Figures 4 to 8 As shown, the outer wall of the movable head 30 is provided with a guide groove 33, and the inner wall of the fixed shell 40 is provided with a guide block 46, and the guide block 46 slides along the guide groove 33. The movable head 30 can move back and forth along the fixed shell 40, and the guide groove 33 also limits the movable head 30 from escaping from the guide groove 33.
[0031] like Figures 1 to 11 As shown, the vehicle window glass breaker also includes a handle 50 and a slider 51. The handle 50 is provided with a storage cavity 53. A slide groove 54 is penetrated through the side wall of the handle 50. The slider 51 is slidably connected with the slide groove 54. The bottom of the slider 51 is connected to the outer wall of the fixed shell 40, and the slide groove 54 protrudes from the top. The slider 51 is used to push the fixed shell 40 to be stored or extended out of the storage cavity 53. When it is not needed, the fixed shell 40 is stored in the storage cavity 53. When it is needed, the slider 51 is slid, and the slider 51 drives the front end of the fixed shell 40 to extend out of the storage cavity 53; after use, the slider 51 is slid, and the slider 51 drives the front end of the fixed shell 40 to be stored in the storage cavity 53 to prevent the fixed shell 40 from being exposed from the storage cavity 53.
[0032] like Figures 3 to 9 As shown, the fixed shell 40 is outerly provided with a second return spring 47, and the second return spring 47 is located in the storage cavity 53. The front end of the storage cavity 53 is provided with a second limiting hole 55, and the aperture of the second limiting hole 55 is smaller than the outer diameter of the fixed shell 40 and larger than the outer diameter of the movable head 30. The outer wall outside the fixed shell 40 is provided with an annular protrusion 48, one end of the second return spring 47 contacts with the annular protrusion 48, and the other end contacts with the front end of the storage cavity 53, and the fixed shell 40 is movably arranged in the storage cavity 53.
