The space between the first mounting groove 21 and the second mounting groove 31 matches the exposed part of the impact assembly 11 and the blade assembly 12 relative to the main body of the safety hammer module 1. The whistle module 2 and the lighting module 3 are detachably mounted on the end of the safety hammer module 1 through the first mounting groove 21 and the second mounting groove 31, and the impact assembly 11 and the blade assembly 12 are both accommodated in the first mounting groove 21 and the second mounting groove 31.

[0044] Through this design, the whistle module 2 and the lighting module 3 can be integrated into the safety hammer module 1, which increases its functionality, makes the structure compact, reduces the overall volume, and facilitates storage and carrying; the first mounting groove 21 and the second mounting groove 31 are detachably mounted on the end of the safety hammer module 1, and can cover the exposed impact assembly 11 and blade assembly 12 when not in use to prevent the user from accidentally touching the impact assembly 11 and the blade assembly 12 and causing unnecessary losses.

[0045] Furthermore, a sealing groove 13 is provided on the end of the safety hammer module 1, the first mounting groove 21 and / or the second mounting groove 31, and a sealing member 14 is provided on the sealing groove 13. The first mounting groove 21 and the second mounting groove 31 are interference-fitted on the end of the safety hammer module 1 through the sealing member 14.

[0046] Specifically, the sealing member 14 is an elastic member.

[0047] In a feasible embodiment, sealing grooves 13 are provided at both ends of the safety hammer module 1 in the length direction, and a sealing member 14 is sleeved on the sealing groove 13. The outer diameter of the sealing member 14 is larger than the inner diameter of the first mounting groove 21 and the second mounting groove 31, so that the first mounting groove 21 and the second mounting groove 31 are interference-fitted on the end of the safety hammer module 1, thereby improving the stability of the connection and preventing the modules from being easily separated after being subjected to external force, resulting in the loss of the functional module.

[0048] In another feasible implementation manner, the sealing groove 13 is disposed on the first mounting groove 21 and the second mounting groove 31 .

[0049] In particular, the sealing groove 13 may also be provided on the safety hammer module 1 and the first mounting groove 21 or the second mounting groove 31 at the same time.

[0052] Specifically, the end of the guide groove 122 away from the impact assembly 11 and the two opposite sides in the length direction are both in communication with the outside.

[0053] It can be understood that the blade bracket 121 is provided with a guide groove 122 relative to the exposed part of the main body of the safety hammer module 1, and the guide groove 122 is arranged along the length direction of the blade bracket 121. The blade 123 is fixed in the guide groove 122, and the cutting edge of the blade 123 is exposed relative to the guide groove 122. The safety belt or other objects to be cut are cut by abutting against the blade 123 through the guide groove 122.

[0054] It should be noted that the side of the guide groove 122 connected to the outside world is perpendicular to the blade end of the blade 123, which makes it easy for objects such as seat belts to extend into the guide groove 122; the blade 123 is blocked by the blade bracket 121 in the opposite direction of the blade 123, avoiding the user from accidentally touching the blade 123 and causing damage, thereby improving the safety of use.

[0055] The design of the guide groove 122 provides a certain shielding for the blade 123 to prevent the user from being accidentally injured by the blade 123 . Secondly, an operating space is also provided for the blade 123 .

[0061] Specifically, the electrical connector 35 is made of conductive material.

[0062] It should be noted that a conductive layer is provided on the circuit board 36 near the end of the rear shell 33. When the front shell 32 and the rear shell 33 are completely threadedly connected, the battery 34 and the electrical connector 35 are both in contact with the conductive layer of the circuit board 36, wherein the end of the electrical connector 35 away from the circuit board 36 is electrically connected to the end of the battery 34 away from the circuit board 36, that is, at this time, the circuit board 36 is electrically connected to the positive and negative poles of the battery 34 at the same time, thereby realizing the circuit connectivity of the lighting module 3.

The first mounting groove and the second mounting groove are interference fit on the end of the safety hammer module through the sealing member, so that the connection between the whistle module and the lighting module and the safety hammer module is more stable, and it is prevented that the modules are easily separated after being subjected to external force, resulting in the loss of the functional module.

[0083] 3. The blade assembly provided in the embodiment of the utility model includes a blade holder. A guide groove is provided at one end of the blade holder away from the impact assembly. A blade is mounted in the guide groove. The blade is mounted in the guide groove and is blocked by the guide groove to prevent the user from accidentally touching the blade and causing damage, thereby improving safety of use.

[0084] 4. The guide slot provided in the embodiment of the utility model is connected to the outside at one end away from the impact assembly and at two opposite sides in the length direction, so that the safety belt or other objects to be cut can be extended from the outside into the guide slot to abut against the blade.

[0085] 5. The lighting module provided in the embodiment of the utility model includes a front shell and a rear shell. The front shell is provided with a first threaded structure, and the rear shell is provided with a second threaded structure that cooperates with the first threaded structure. The first threaded structure cooperates with the second threaded structure to fix the front shell and the rear shell together, and the degree of connection between the front shell and the rear shell can be controlled by the number of cooperating thread turns.

[0086] 6. The rear shell provided in the embodiment of the utility model is equipped with a battery and an electrical connector, and a circuit board is provided at the mating ends of the front shell and the rear shell. After the front shell and the rear shell are assembled, the electrical connector is electrically connected to the end of the battery away from the front shell and the circuit board respectively, thereby realizing the circuit connectivity of the lighting module. Specifically, this embodiment realizes the connection and disconnection of the circuit in the lighting module through the degree of threaded connection between the front and rear shells.

[0087] 7. The safety hammer module provided by the embodiment of the utility model includes a shell, a chamber is provided in the shell, and the impact assembly is partially accommodated in the chamber. The impact assembly includes a spring group and a striker mounted on the spring group. The impact effect is achieved by pulling the striker to move through the elastic deformation process of the spring group. A limit plate abutting the spring group is provided in the chamber to limit the transitional movement of the spring group so that it can be compressed, so that a larger elastic thrust can be generated after resetting to make the striker hit the window.

[0088] 8. The chamber side wall provided by the embodiment of the utility model is provided with a first sliding structure and a first limiting structure, the impact assembly includes a compression piece, and the compression piece is provided with a second sliding structure cooperating with the first sliding structure and a second limiting structure cooperating with the first limiting structure on the periphery of the compression piece. The two cooperate to fix the compression piece in the chamber to prevent it from leaving the chamber under the action of the spring group. The first sliding structure and the second sliding structure cooperate to slide the compression piece in the chamber. The compression piece slides in the chamber to compress the spring group, causing it to produce elastic deformation.

[0089] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included in the protection scope of the present invention.
