[Technical Field]

[0001] This utility model relates to the field of safety hammer technology, and in particular to a multifunctional safety hammer. [Background Technology]

[0002] Safety hammers are important emergency escape devices, widely used in public transportation, private cars, and high-rise buildings. They are mainly used to break tempered or laminated glass in emergency situations for quick escape. Safety hammers typically feature a pointed or conical head design, concentrating force on a specific point in the glass to break it.

[0003] Safety hammers typically integrate multiple functions to address various emergency situations, such as window breaker, lighting, and blades.

[0015] Compared with the prior art, the multifunctional safety hammer provided by this utility model has the following advantages:

[0016] 1. This utility model provides a multifunctional safety hammer that integrates a window breaker, a lighting structure, and a blade. The safety hammer includes a housing assembly, a window breaker assembly, a lighting assembly, and a blade. By arranging the window breaker assembly and the blade side by side and the lighting assembly and the blade coaxially, the overall length of the safety hammer is significantly shortened, improving portability. Furthermore, by exposing the working ends of the window breaker assembly and the blade on the same side of the main housing, users can quickly switch between different functions when using the safety hammer without repeatedly adjusting their grip, significantly improving operational efficiency for rapid escape. The window breaker assembly and the blade share the same cover, which protects the working ends of the window breaker assembly and the blade, preventing accidental operation when not in use, and also facilitates quick access, improving the safety of the safety hammer.

[0017] 2. In the safety hammer provided in this embodiment of the present invention, the window-breaking component includes a pin assembly and a hammer head assembly with an ejection hole. The hammer head assembly is used to locate the position to be struck and to accumulate potential energy for the impact of the pin assembly. The pin assembly uses the potential energy accumulated by the hammer head assembly to strike the position to be struck on the glass. The central axis of the ejection hole intersects with the central axis of the pin assembly. Through the interaction between the hammer head assembly and the pin assembly, the pin assembly can eventually slide relative to the hammer head assembly toward the ejection hole. The hammer head assembly can slide relative to the main shell and release the pin assembly to strike the glass after accumulating potential energy. This process does not require additional devices, making the structure of the safety hammer simpler.

[0018] 3. In the safety hammer provided in this embodiment of the utility model, the first elastic element, which serves as the ejector spring, is sleeved on the ejector body and abuts against the first limiting element and the main shell respectively. The ejector body accumulates potential energy through the first elastic element, and at the same time, it also facilitates the ejector body to successfully return to the interior of the hammer head assembly after extending and breaking the window.

[0019] 4. In the safety hammer provided in this embodiment of the present invention, the outer diameter of the ejector pin body needs to be less than or equal to the inner diameter of the ejector hole, so that the end of the ejector pin body can punch out of the ejector hole to break the glass; on this basis, the outer diameter of the first limiting member needs to be greater than or equal to the outer diameter of the first elastic member, so as to ensure that the end of the first elastic member near the ejector hole is stably supported by the first limiting member, and to avoid the first elastic member losing its elastic effect on the ejector pin body and the first limiting member, thereby affecting the window breaking effect; the outer diameter of the first limiting member needs to be greater than the inner diameter of the ejector hole, so as to prevent the ejector pin body from being completely punched out of the ejector hole and unable to retract, and to provide a large instantaneous potential energy to the ejector pin body when the end of the ejector pin body punches out of the ejector hole.

[0020] 5. In the safety hammer provided in this embodiment of the utility model, the hammer head assembly includes a hammer head body and a second elastic element, and a second limiting element is provided on the hammer head body. The second elastic element, which serves as a reset spring, abuts against the second limiting element and the main shell respectively. Through this design, the safety hammer is less likely to be accidentally operated when not in use, and the hammer head body can be easily controlled to return to the initial position after the ejector pin body punches out of the ejector hole and breaks the glass.

[0021] 6. In the safety hammer provided in this embodiment of the present invention, the end of the first limiting member facing the ejection hole abuts against the driving part provided on the inner wall surface of the hammer head body. When the window breaking assembly is used, the hammer head assembly rotates along the central axis of the ejection hole toward the direction where the ejector pin assembly is located. At this time, the first elastic member is compressed, causing the ejector pin body to accumulate potential energy. By setting the guide groove, the position of the central axis of the ejector pin assembly can be adjusted, and the central axis of the ejector pin assembly can be offset toward the central axis of the ejection hole until they coincide. When the hammer head assembly moves away from the ejection hole, the first limiting member separates from the hammer head body.

[0022] 7. In the safety hammer provided in this embodiment of the utility model, an anti-slip shell is provided at one end of the main shell away from the cover. The anti-slip shell is designed to work in conjunction with the window breaking component and the blade. By setting strip-shaped anti-slip particles on the outer surface of the anti-slip shell, it can be ensured that the window breaking component or the blade on the safety hammer can be firmly gripped in an emergency, increasing the friction between the user's palm and the safety hammer, and significantly improving the escape efficiency.

[0023] 8. In the safety hammer provided in this embodiment of the utility model, the lighting component includes a lamp body assembly, a control circuit board, and an energy storage component installed on the main shell. The energy storage component is electrically connected to the input terminal of the control circuit board, and the lamp tube is electrically connected to the output terminal of the control circuit board. The lighting component on the safety hammer is used to provide illumination when the light is poor, and is suitable for various emergency situations. The lamp cover is fitted over the lamp tube to protect the lamp tube and extend the service life of the lighting component.

[0024] 9. In the safety hammer provided in this embodiment of the utility model, the blade can quickly cut ropes, thread ends and safety belts; by setting a concave cutting groove on the main shell, and the blade edge is set obliquely in the cutting groove, the operation of cutting ropes, thread ends and safety belts can be faster and more convenient, thereby improving the ease of use of the safety hammer; the blade is detachably fixed to the mounting boss through the mounting hole, so that the installation of the blade is more secure when the first shell and the second shell are closed, and it is also convenient to disassemble and replace the blade.

[0042] Furthermore, in addition to indicating direction or positional relationship, some of the aforementioned terms may also have other meanings. For example, the term "above" may also be used in some cases to indicate a certain dependency or connection relationship. Those skilled in the art can understand the specific meaning of these terms in this utility model according to the specific circumstances.

[0043] Furthermore, the terms "installation," "setup," "equipped with," "connection," and "linked" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of these terms in this utility model based on the specific circumstances.

[0044] Please see Figure 1 and Figure 2 This utility model provides a multifunctional safety hammer 100, which includes a housing assembly 1, a window-breaking assembly 2, a lighting assembly 3, and a blade 4. The housing assembly 1 includes a main shell 11 and a cover 12. The window-breaking assembly 2, the lighting assembly 3, and the blade 4 are all installed on the main shell 11, and the window-breaking assembly 2 can slide relative to the main shell 11. The window-breaking assembly 2 and the blade 4 are arranged side by side, and the lighting assembly 3 and the blade 4 are arranged coaxially. The working end of the lighting assembly 3 is exposed on one side of the main shell 11, and the working end of the window-breaking assembly 2 and the working end of the blade 4 are exposed on the other side of the main shell 11.

[0045] Furthermore, the cover 12 is detachably fitted onto the side of the main housing 11 away from the working end of the lighting component 3, so as to cover the working end of the window breaking component 2 and the working end of the blade 4.

[0046] The safety hammer 100 provided by this utility model integrates functional components including a window breaking component 2, a lighting component 3, and a blade 4. By arranging the window breaking component 2 and the blade 4 side by side and the lighting component 3 and the blade 4 coaxially, the overall length of the safety hammer 100 is significantly shortened, improving its portability. This design solves the technical problem that the existing safety hammers have a relatively complex structure and the multiple integrated functional components are scattered, which may lead to a decrease in escape efficiency. This design improves the escape efficiency of using the safety hammer in emergency situations.

[0047] Specifically, the window breaking component 2, the lighting component 3, and the blade 4 are all installed on the main housing 11. The window breaking component 2 can slide relative to the main housing 11. On this basis, the working end of the window breaking component 2 and the working end of the blade 4 are exposed on the same side of the main housing 11. When using the safety hammer 100, the user can quickly switch between using the window breaking function and the cutting function without repeatedly adjusting the grip, which significantly improves the operating efficiency and facilitates rapid escape.

[0048] Understandably, exposing the working end of the lighting component 3 on the other side of the main housing 11 makes the overall structure of the safety hammer 100 more compact and reduces the manufacturing cost of the safety hammer 100. The lighting component 3 can provide illumination in low light conditions and is suitable for various emergency situations.

[0049] Furthermore, the housing assembly 1 includes a main housing 11 and a cover 12. The main housing 11 is used to support and install the window breaking assembly 2, the lighting assembly 3 and the blade 4, while the cover 12 is detachably fitted on the side of the main housing 11 away from the working end of the lighting assembly 3. That is, the cover 12 is fitted on the working end of the window breaking assembly 2 and the working end of the blade 4 to cover the working ends of the window breaking assembly 2 and the blade 4.

[0050] It should be noted that the design of the window breaking component 2 and the blade 4 sharing the same cover 12 can not only protect the working ends of the window breaking component 2 and the blade 4 to prevent accidental operation when not in use, but also facilitate the quick access of the window breaking component 2 and the blade 4, thereby greatly improving the safety of the safety hammer 100.

[0051] Specifically, the main shell 11 and the cover 12 are detachably connected so that the window breaking component 2 and / or the blade 4 can be used in the disassembled state. The detachable connection method includes, but is not limited to, snap-fit ​​connection, magnetic connection, and plug-in connection. In this embodiment of the present invention, the connection method between the main shell 11 and the cover 12 is a snap-fit ​​connection to ensure the safety of the safety hammer 100. When the main shell 11 and the cover 12 are connected or disassembled, the snap-fit ​​connection method can transmit damping feedback to the user, so that the user can know whether the main shell 11 and the cover 12 are currently fixedly connected, so as to further prevent accidental operation of the window breaking component 2 and the blade 4 and improve the user experience of the safety hammer 100.

[0052] It is understood that the type of detachable connection between the main shell 11 and the cover 12 can be adjusted according to actual needs. The above-described snap-fit ​​connection method is only one embodiment of this utility model and is not intended to limit this utility model. Any modifications, equivalent substitutions and improvements made within the principles of this utility model should be included within the protection scope of this utility model.

[0053] Please see Figure 2 and Figure 3 The window breaking assembly 2 includes a pin assembly 21 and a hammer assembly 22 with an ejection hole 221. The hammer assembly 22 is slidably mounted on the main housing 11, and the pin assembly 21 is placed inside the hammer assembly 22. The hammer assembly 22 has an ejection hole 221. The pin assembly 21 can punch out of the ejection hole 221 under the action of the first elastic member 213 to break the glass. The central axis of the ejection hole 221 intersects with the central axis of the pin assembly 21. When the window breaking assembly 2 is used to break the glass, the central axis of the pin assembly 21 can be rotated to coincide with the central axis of the ejection hole 221.

[0054] Understandably, in the safety hammer 100 provided in this embodiment of the present invention, the window breaking component 2 includes a hammer head component 22 and a pin component 21 disposed inside the hammer head component 22. The hammer head component 22 is used to position the position to be struck on the glass and accumulate potential energy for the striking of the pin component 21. The pin component 21 then uses the potential energy accumulated by the hammer head component 22 to strike the position to be struck on the glass.

[0055] It should be noted that, under normal conditions, the ejector pin assembly 21 is located inside the hammer head assembly 22. When the hammer head assembly 22 is pushed from one end of the ejection hole 221 to slide relative to the main housing 11, the ejector pin assembly 21 moves relative to the hammer head assembly 22. During this process, the central axis of the ejector pin assembly 21 rotates toward the central axis of the ejection hole 221.

[0056] Furthermore, the side of the hammer assembly 22 near the ejector hole 221 needs to protrude outward relative to the main shell 11 in the normal state when the window-breaking assembly 2 is not used. That is, in this embodiment of the present invention, the portion of the hammer assembly 22 exposed on the main shell 11 protrudes outward relative to the main shell 11. This design allows the hammer assembly 22 to slide relative to the main shell 11, thereby accumulating potential energy for the striking of the ejector assembly 21.

[0057] Furthermore, the central axis of the ejector hole 221 ( Figure 2 The dotted line ① in the middle is parallel to the central axis of the ejector pin assembly 21. Figure 2 The dotted lines ②) are intersecting, and through the interaction between the hammer assembly 22 and the ejector assembly 21: when the hammer assembly 22 slides relative to the main shell 11, it pushes the ejector assembly 21 to move a certain distance away from the ejection hole 221, so that the ejector assembly 21 can slide relative to the hammer assembly 22 towards the ejection hole 221; the hammer assembly 22 can slide relative to the main shell 11, and when the first elastic element 213 is squeezed, it accumulates potential energy and finally releases the ejector assembly 21 to hit the glass. This process does not require additional devices, making the structure of the safety hammer 100 simpler.

[0058] In an embodiment of this utility model, when the window breaking component 2 is in an unused state, the ejector pin component 21 is placed at a certain angle inside the hammer head component 22 so that the central axis of the ejector pin component 21 intersects with the central axis of the ejection hole 221. At this time, the end of the ejector pin component 21 near the ejection hole 221 abuts against the inner wall surface of the hammer head component 22.

[0059] When the window breaking assembly 2 is in use, the hammer assembly 22 can slide relative to the main housing 11 to the side away from the ejector hole 221. Before the hammer assembly 22 releases the ejector pin assembly 21, the central axis of the ejector pin assembly 21 rotates toward the central axis of the ejector hole 221. When the central axis of the ejector pin assembly 21 rotates under the guidance of the first limiting member 212 to coincide with the central axis of the ejector hole 221, the ejector pin assembly 21 punches out of the ejector hole 221 and hits the glass.

[0060] Please see Figure 2 , Figure 3 and Figure 4 The ejector assembly 21 includes an ejector body 211, a first limiting member 212, and a first elastic member 213. The ejector body 211 is movably mounted on the main housing 11. The first limiting member 212 is fixedly connected to the ejector body 211 on the side near the ejection hole 221, and the first limiting member 212 can slide relative to the main housing 11. The first elastic member 213 is sleeved on the ejector body 211, and the two ends of the first elastic member 213 abut against the first limiting member 212 and the main housing 11, respectively.

[0061] In the safety hammer 100 provided in this embodiment of the present invention, the first elastic member 213, which serves as the ejector spring, is sleeved on the side of the ejector body 211 away from the ejector hole 221, and abuts against the first limiting member 212 and the main shell 11 respectively. Through this design, the window breaking component 2 of the safety hammer 100 is not easily operated by mistake when not in use. It also makes it easy for the hammer head component 22 to reset after the ejector body 211 breaks the glass by punching out of the ejector hole 221, so that the ejector body 211 can move back to the initial position inside the hammer head component 22 in the normal state.

[0062] Understandably, the first elastic member 213 is mainly used to cooperate with the first limiting member 212 fixed on the ejector body 211. When the window breaking assembly 2 is in an unused state, the first elastic member 213 is in a natural state, and the two ends of the first elastic member 213 abut against the first limiting member 212 and the main shell 11, respectively; the inner sidewall of the main shell 11 is provided with a limiting part 113, and in this embodiment, the end of the first elastic member 213 away from the first limiting member 212 abuts against the limiting part 113.

[0063] When the window breaking assembly 2 is in use, the first limiting member 212 moves toward the first elastic member 213 to compress the first elastic member 213. At this time, the first elastic member 213 is in a deformed state. Subsequently, the first elastic member 213 can provide instantaneous potential energy for the ejector body 211 to punch out of the ejector hole 221, releasing a powerful impact force to allow the end of the ejector body 211 to shatter the glass.

[0064] In some embodiments, the end of the ejector pin body 211 is a pointed or conical head, a design that concentrates force on the point of impact on the glass, making it easier to break tempered or laminated glass.

[0065] In some embodiments, the outer diameter of the ejector body 211 is less than or equal to the inner diameter of the ejector hole 221; this design allows the end of the ejector body 211 to punch out of the ejector hole 221 to shatter the glass.

[0066] In some embodiments, the outer diameter of the first limiting member 212 is greater than or equal to the outer diameter of the first elastic member 213. This design ensures that the end of the first elastic member 213 near the ejector hole 221 is stably supported by the first limiting member 212, preventing the first elastic member 213 from losing its elastic effect on the ejector body 211 and the first limiting member 212, thereby affecting the window breaking effect.

[0067] In some embodiments, the side of the first limiting member 212 facing the ejector hole 221 abuts against the hammer assembly 22, and the outer diameter of the first limiting member 212 is larger than the inner diameter of the ejector hole 221. With this design, the ejector body 211 can be prevented from being completely ejected out of the ejector hole 221 and unable to be retracted, and when the end of the ejector body 211 ejects out of the ejector hole 221, it provides a large instantaneous potential energy to the ejector body 211.

[0068] Please continue reading. Figure 2 , Figure 3 and Figure 4 The hammer assembly 22 includes a hammer body 222 and a second elastic member 223. The hammer body 222 is movably mounted on the main housing 11. The inner diameter of the second elastic member 223 is larger than the outer diameter of the first elastic member 213. A second limiting member 224 is provided on the hammer body 222. The second limiting member 224 is located on the side of the hammer body 222 away from the ejection hole 221 and the circumferential direction of the second limiting member 224 is slidably engaged with the main housing 11. The end of the second elastic member 223 facing the ejection hole 221 abuts against the second limiting member 224, and the end of the second elastic member 223 away from the ejection hole 221 abuts against the main housing 11.

[0069] In the safety hammer 100 provided in this embodiment of the utility model, the second elastic member 223, which serves as a reset spring, abuts against the second limiting member 224 and the main shell 11 respectively. This design makes it less likely for the safety hammer 100 to be accidentally operated when not in use, and also makes it easier to control the hammer head body 222 to return to the initial position after the ejector pin body 211 breaks the glass by punching out of the ejector hole 221.

[0070] Understandably, the second elastic member 223 is mainly used to cooperate with the second limiting member 224 on the hammer head body 222. When the window breaking assembly 2 is in an unused state, the second elastic member 223 is in a natural state, and both ends of the second elastic member 223 abut against the second limiting member 224 and the main shell 11, respectively; the inner sidewall of the main shell 11 is provided with a limiting part 113, and in this embodiment, the end of the second elastic member 223 away from the second limiting member 224 abuts against the limiting part 113.

[0071] When the window breaking assembly 2 is in use, the second limiting member 224 moves toward the second elastic member 223 to compress the second elastic member 223. At this time, the second elastic member 223 is in a deformed state. Subsequently, after the release of the ejector assembly 21 and the ejector body 211 extends out of the ejection hole 221 to hit the glass, the second elastic member 223 can reset the hammer body 222. Specifically, the second elastic member 223 provides a certain buffering force to the hammer body 222. During the process of the second elastic member 223 slowly returning to its natural state, the hammer body 222 is driven back to its initial position by pushing the second limiting member 224.

[0072] It should be noted that the inner diameter of the second elastic element 223 needs to be larger than the outer diameter of the first elastic element 213, so that the process of the ejector pin body 211 extending out of the ejector hole 221 to hit the glass and the hammer head body 222 returning to the initial position will not conflict, thus extending the service life of the safety hammer 100. On this basis, the second elastic element 223 can also make the hammer head body 222 slide in the direction of the central axis of the ejector hole 221 without deflection. The two ends of the second elastic element 223 respectively abut against the second limiting member 224 and the main shell 11, which can ensure the stability of the second elastic element 223 in completing the reset action of the hammer head body 222.

[0073] Please continue reading. Figure 2 , Figure 3 and Figure 4 The inner wall of the hammer body 222 is provided with a driving part 2221, and the end of the first limiting member 212 facing the ejection hole 221 abuts against the driving part 2221; the hammer body 222 and the inner wall of the main shell 11 form a receiving cavity 10 for placing the ejector pin assembly 21. The inner wall of the receiving cavity 10 is provided with a guide groove 20 for the first limiting member 212 to slide through, and the distance between the guide groove 20 and the ejector pin assembly 21 decreases in the direction away from the ejection hole 221.

[0074] Understandably, when the window breaking assembly 2 is in use, the hammer assembly 22 rotates along the central axis of the ejector hole 221 toward the direction of the ejector assembly 21. At this time, the first elastic element 213 is compressed, causing the ejector body 211 to accumulate potential energy.

[0075] Specifically, the hammer head body 222 first positions the position to be struck on the glass. After the ejector hole 221 is aligned with the position to be struck, the safety hammer 100 is pushed in the direction of the position to be struck, causing the hammer head body 222 to slide relative to the main shell 11. Since one end of the first limiting member 212 sleeved on the ejector pin body 211 abuts against the driving part 2221 on the inner wall of the hammer head body 222, the first limiting member 212 and the ejector pin body 211 will move together when the hammer head body 222 slides. The two ends of the first elastic member 213 abut against the first limiting member 212 and the main shell 11 respectively. When the first limiting member 212 and the ejector pin body 211 move together, the first elastic member 213 is compressed to accumulate potential energy.

[0076] In the safety hammer 100 provided in this embodiment of the utility model, the position of the central axis of the ejector assembly 21 can be adjusted by setting the guide groove 20, so that the central axis of the ejector assembly 21 is offset towards the central axis of the ejector hole 221 until they coincide. When the hammer head assembly 22 moves in a direction away from the ejector hole 221, the first limiting member 212 separates from the hammer head body 222.

[0077] It should be noted that the driving part 2221 on the hammer body 222 can push the first limiting member 212 to the guide groove 20. When the first limiting member 212 slides through the guide groove 20, the distance between the first limiting member 212 and the ejection hole 221 gradually increases, and the central axis of the ejector assembly 21 shifts toward the central axis of the ejection hole 221.

[0078] When the first limiting member 212 has completely passed through the guide groove 20, the central axis of the ejector body 211 coincides with the central axis of the ejector hole 221. At this time, the ejector body 211 relies on the potential energy accumulated by the first elastic member 213 to quickly extend into the ejector hole 221 to strike the glass.

[0079] For further details, please refer to Figure 1 and Figure 5 The housing assembly 1 also includes an anti-slip outer shell 13, which is fitted onto the main housing 11 at the end away from the cover 12. The outer surface of the anti-slip outer shell 13 is provided with strip-shaped anti-slip particles 131, and the length of the anti-slip particles 131 gradually increases from the central axis of the main housing 11 toward the side away from the lighting assembly 3.

[0080] In the safety hammer 100 provided in this embodiment of the utility model, an anti-slip shell 13 is provided at one end of the main shell 11 away from the cover 12. The anti-slip shell 13 is provided to cooperate with the window breaking component 2 and the blade 4.

[0081] Understandably, by setting strip-shaped anti-slip particles 131 on the surface of the anti-slip housing 13, it can be ensured that the window-breaking component 2 or blade 4 on the safety hammer 100 can be firmly gripped in an emergency, increasing the friction between the user's palm and the safety hammer 100, thereby significantly improving escape efficiency for rapid escape.

[0082] It should be noted that the length of the anti-slip particles 131 gradually increases from the central axis of the main shell 11 toward the side away from the lighting component 3. Through the gradual length design of the anti-slip particles 131, the grip feel is further optimized and the comfort of using the safety hammer 100 is improved.

[0083] In this embodiment of the invention, the strip-shaped anti-slip particles 131 not only make the safety hammer 100 more aesthetically pleasing, but also evenly distribute the grip pressure and improve the anti-slip effect. In addition, the anti-slip particles 131 can also adopt other regular geometric shapes, such as circles, ellipses, polygons or rhombuses. The strip-shaped anti-slip particles 131 are only one embodiment of this invention and are not intended to limit this invention. Other shapes of anti-slip particles 131 that meet the conditions should also be considered as equivalent substitutions for this embodiment, and will not be described in detail here.

[0084] Please continue reading. Figure 1 and Figure 5 The lighting component 3 includes a lamp body assembly 31, a control circuit board 32, and an energy storage component 33. The lamp body assembly 31, the control circuit board 32, and the energy storage component 33 are installed on the main housing 11. The lamp body assembly 31 includes a lamp tube 311 and a lamp cover 312 sleeved on the lamp tube 311. The lamp tube 311 and the energy storage component 33 are electrically connected to the control circuit board 32 respectively.

[0085] In this embodiment of the invention, the safety hammer 100 is equipped with a lighting component 3 to provide illumination in low-light conditions, suitable for various emergency situations. The energy storage component 33 is electrically connected to the input terminal of the control circuit board 32, and the lamp tube 311 is electrically connected to the output terminal of the control circuit board 32, so that the energy storage component 33 supplies power to the lamp tube 311.

[0086] It should be noted that the lamp cover 312 in the lamp body assembly 31 is fitted onto the lamp tube 311. The lamp cover 312 can protect the lamp tube 311, thereby extending the service life of the lighting assembly 3.

[0087] In some embodiments, the lighting assembly 3 further includes a charging interface 34 and a switch 35 disposed on the main housing 11. Specifically, the charging interface 34 is of USB-C type, and the energy storage device 33 can be charged through the charging interface 34; when the energy storage device 33 has sufficient power, the lighting assembly 3 can be turned on when needed and turned off when not needed by the switch 35 and the energy storage device 33.

[0088] Please see Figure 1 and Figure 6 The main shell 11 is provided with a recessed cutting groove 30, and the cutting edge of the blade 4 is inclinedly set in the cutting groove 30.

[0089] In the safety hammer 100 provided in this embodiment of the utility model, the blade 4 can quickly cut ropes, thread ends and safety belts; through this design, the operation of cutting ropes, thread ends and safety belts can be faster and more convenient, thereby improving the ease of use of the safety hammer 100.

[0090] It should be noted that the angle at which the blade of the blade 4 is tilted is the same as the angle between the blade of the blade 4 and the central axis of the cutting groove 30. The tilt angle ranges from 15° to 45°. In this embodiment, the tilt angle of the blade 4 is 30°, which can improve the efficiency and success rate of cutting ropes, thread ends and safety belts with the blade 4.

[0091] Furthermore, the main housing 11 includes a coverable first housing 111 and a second housing 112, with a mounting boss 40 on the first housing 111 or the second housing 112; the blade 4 is provided with a mounting hole 41 that mates with the mounting boss 40, and the blade 4 is detachably fixed to the mounting boss 40 through the mounting hole 41.

[0092] In some embodiments, the first housing 111 or the second housing 112 is further provided with a mounting frame 50. While the blade 4 is fixed to the mounting boss 40, the mounting frame 50 abuts against the outer side wall of the blade 4. The present invention embodiment achieves the limitation of the blade by the mounting frame 50 and the mounting boss 40, which further improves the stability of the blade 4 installed on the housing 11 and also improves the safety of using the blade 4 in emergency situations.

[0093] As an optional implementation, the mounting boss 40 and the mounting frame 50 are both provided on the first housing 111; it can be understood that the mounting boss 40 and the mounting frame 50 can be selected to be provided on the first housing 111 or the second housing 112, and can be adjusted accordingly according to the actual internal structure of the safety hammer 100.

[0094] Understandably, the blade 4 is detachably fixed to the mounting boss 40 through the mounting hole 41, so that the blade 4 is more securely installed when the first housing 111 and the second housing 112 are closed, and the blade 4 is also easy to disassemble and replace when the first housing 111 and the second housing 112 are separated.

[0095] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the principles of the present utility model should be included within the protection scope of the present utility model.
