[0032] Combined with reference Figure 1 In the first embodiment of the present application, a flashlight including a flashlight body 3 and a knife assembly 1 is provided. The two sides of the flashlight body 3 are oppositely provided with an upper shell 2 and a lower shell 6. The upper shell 2 and the flashlight body 3 are covered to form a mounting cavity. The lower shell 6 and the flashlight body 3 are covered to form a placing cavity. The flashlight body 3 is further provided with a light source group 43 and a power supply assembly 5. The light source group 43 is electrically connected with the power supply assembly 5. The light source group 43 is located on the side of the flashlight body 3 away from the mounting cavity. The power supply assembly 5 is located in the placing cavity. The knife assembly 1 is movably arranged in the mounting cavity. The knife assembly 1 includes a blade 11. The blade 11 is detachably connected with the upper shell 2. One end of the upper shell 2 is further provided with a slot for pushing out the blade 11.

[0033] In addition, in some embodiments, the upper shell 2 and the lower shell 6 can be an integral structure, that is, the upper shell 2 and the lower shell 6 are integrally sleeved on the flashlight body 3. Similarly, the upper shell 2, the lower shell 6 and the flashlight body 3 can also be an integral structure, that is, the upper shell 2, the lower shell 6 and the flashlight body 3 are an integral body composed of the same material, and the shape of the flashlight body 3 and the upper shell 2 and the lower shell 6 is not limited in the present application, which can be cylindrical or columnar.

[0034] This embodiment of a flashlight with a quick-change blade includes a flashlight body 3 and a blade assembly 1. The blade assembly 1 is movably disposed within the mounting cavity formed by the flashlight body 3 and the upper housing 2, and its position can be fixed after installation. The light source group 43 and the blade assembly 1 are located on different sides of the flashlight body 3, and the power supply assembly 5 and the blade assembly 1 are located in different cavities. The blade assembly 1 is independent of the light source group 43 and the power supply assembly 5. When the blade assembly 1 is replaced or used, it will not affect the connection between the power supply assembly 5 and the light source group 43, and will not affect the realization of the lighting function. In addition, the blade assembly 1 includes a blade, which can be slid out from the slot for quick disassembly, improving the user experience.

[0035] In some embodiments, the tool assembly 1 further includes a pusher 12 and a snap-fit ​​fastener 13; the blade 11 is detachably disposed between the pusher 12 and the snap-fit ​​fastener 13, the pusher 12 and the snap-fit ​​fastener 13 are detachably connected, and one end of the upper housing 2 is also provided with a slot for pushing out the blade 11; a push button 22 is provided on the upper housing 2, and the push button 22 is connected to the pusher 12; the push button 22 is used to push the pusher 12, thereby driving the blade 11 to move.

[0036] Specifically, the installation process of the tool assembly 1 is as follows: place the blade 11 between the pusher 12 and the snap-fit ​​fastener 13, then connect the pusher 12 and the snap-fit ​​fastener 13 to assemble the tool assembly 1; then place the assembled tool assembly 1 on the upper housing 2, with the blade 11 corresponding to the slot position, and then cover the upper housing 2 with the flashlight body 3, so that the tool assembly 1 is connected to the flashlight body 3.

[0037] The flashlight body 3 and the upper shell 2, and the flashlight body 3 and the lower shell 6 can be connected by snap-fit, screw, bolt, magnetic connection or other means.

[0038] The snap-fit ​​fastener 13 is used to connect the pusher 12 and the blade 11. The snap-fit ​​fastener 13 is detachably connected to the pusher 12. Specifically, the pusher 12 is provided with a first connecting hole 123 for fixed connection with the snap-fit ​​fastener 13. The snap-fit ​​fastener 13 is provided with a protrusion corresponding to the first connecting hole 123. The protrusion engages with the first connecting hole 123 to clamp the blade 11 between the snap-fit ​​fastener 13 and the pusher 12. Alternatively, the blade 11 may be provided with a protrusion corresponding to the first connecting hole 123. The through hole allows the protrusion to pass through and engage with the first connecting hole 123, thereby fixing the position of the blade 11. Alternatively, a through hole corresponding to the first connecting hole 123 can be provided on the snap-fit ​​fastener 13, along with a connecting rod corresponding to the first connecting hole 123. The connecting rod passes through the corresponding through hole on the snap-fit ​​fastener 13, and / or the corresponding through hole on the blade 11, as well as the first connecting hole 123, to fix the blade 11 between the snap-fit ​​fastener 13 and the pusher 12. The connecting rod can be a screw, bolt, or the like.

[0039] The drive mechanism, which moves the pusher 12 via the push button 22 on the upper housing 2, thereby causing the blade 11 to move, is simple and easy to operate. Furthermore, the length of the exposed blade 11 can be controlled according to the pushing force, making it convenient for the user. After the blade 11 is fully extended or the locking fastener 13 is extended, the blade 11 can be replaced. Specifically, after exposing the connection between the blade 11 and the locking fastener 13, the blade 11 can be removed for replacement. This replacement method is simple, flexible, and requires no additional tools.

[0040] In some embodiments, a front cover 7 is provided on one side of the flashlight body 3, and a mounting part 27 extends from one side of the upper housing 2; the flashlight with quick-change blades also includes a light source group 43, which is disposed in the mounting part 27, the front cover 7 is sleeved on the mounting part 27, and the slot is provided on the blade assembly 1 at the opposite position of the side wall of the front cover 7.

[0041] The light source assembly 43 is located in the mounting section 27 and emits light through the front cover 7, thus providing illumination. The cutting tool assembly 1 is located on the side wall of the front cover 7, separated from the light source assembly 43. This ensures that the illumination function of the light source assembly 43 and the cutting function of the cutting tool assembly 1 are independent, allowing for single or simultaneous use as needed. Furthermore, since the light source assembly 43 and the cutting tool assembly 1 are located in different cavities, the replacement of the blade 11 in the cutting tool assembly 1 will not affect the light source assembly 43 or its functionality. Additionally, this design prevents the sharp edges of the blade 11 in the cutting tool assembly 1 from damaging the light source assembly 43 and the power supply assembly 5.

[0042] The light source group 43 and the knife assembly 1 can be located at the same end of the flashlight body 3, or the light source group 43 and the knife assembly 1 can be axially opposite to each other at both ends of the flashlight body; this can be set according to the user's habits or needs, improving the user experience; the light source group 43 and the knife assembly 1 are preferably located at the same end of the flashlight body 3, which facilitates the switching or combination of functions in dark environments.

[0043] In some embodiments, the flashlight body 3 is also provided with a control component 4, which is electrically connected to the power supply component 5; the light source group 43 is electrically connected to the control component 4, and is electrically connected to the power supply component 5 through the control component 4.

[0044] In some embodiments, the upper housing 2 is provided with a movable slide 21; the tool assembly is located in the movable slide 21, and a push button 22 pushes the tool assembly to move along the movable slide 21. (Refer to the reference...) Figure 2 Furthermore, the inner side of the movable slide 21 is provided with several locking grooves 211. The push button 22 passes through the movable slide 21 and is connected to the push member 12. The push button 22 is provided with a locking protrusion 221; the locking grooves 211 are used to engage and fix with the locking protrusion 221. Specifically, the push button 22 is located in the movable slide 21 and is connected to the push member 12 through the movable slide 21.

[0045] The locking groove 211 and the locking protrusion 221 can engage and fix the push button 22, thereby locking the position of the push button 22. In the locked state, the blade 11 cannot move, thus achieving the effect of locking the blade 11 through the locking groove 211 and the locking protrusion 221. Therefore, when the blade 11 is not needed, it can be completely retracted into the cavity and locked by the locking groove 211 and the locking protrusion 221 to prevent the blade 11 from suddenly protruding and causing injury to the user. When the blade 11 needs to be used, locking it after protruding a certain length of the blade 11 can also prevent the blade 11 from being loose, resulting in insufficient cutting force. When the blade 11 needs to be replaced, the locking protrusion 221 on the push button 22 is separated from the locking groove 211, so that the blade 11 is in the unlocked state, facilitating the replacement of the blade 11. Specifically, the number of locking grooves 211 can be set according to actual needs.

[0046] Furthermore, the pusher 12 is provided with a fixing groove 122 corresponding to the push button 22, and a pressing spring 14 is provided between the push button 22 and the fixing groove 122; the pressing spring 14 is used to lock the locking groove 211 and the locking protrusion 221. Specifically, one end of the pusher 12 is the output end and the other end is the fixed end; the fixing groove 122 is located on the pusher 12 near the fixed end, and the blade 11 is located on the output end of the pusher 12, that is, the blade 11 is located on the pusher 12 away from the fixed end.

[0047] The pusher 12 and the push button 22 abut against each other via a locking protrusion 221 and a fixing groove 122. Specifically, a pressing spring 14 is sleeved on the locking protrusion 221 and located between the locking protrusion 221 and the fixing groove 122. The locking protrusion 221 is fixed in the axial direction by abutting against the fixing groove 122 via the pressing spring 14, and in the horizontal direction it directly engages with the locking groove 211, thereby fixing the position of the push button 22 on the movable slide 21.

[0048] In the unlocked state, the pressing spring 14 is always under pressure, which can push the button 22 to move along the movable slide 21. When the button 22 is pushed to any locking groove, the locking protrusion 221 is inserted into the locking groove 211. The elastic restoring force of the pressing spring 14 ensures that the locking protrusion 221 and the locking groove 211 are tightly engaged, thereby locking the push button 22. When unlocking is required, the push button 22 is pressed to separate the locking protrusion 221 from the locking groove 211.

[0049] Furthermore, the blade 11 is provided with a slot 111, and the snap-fit ​​fastener 13 is provided with a pin 131 corresponding to the slot 111. The pin 131 passes through the slot 111 and abuts against the pusher 12. That is, the blade 11 can be fixedly connected to the pusher 12 by the slot 111 on the blade 11 and the pin 131 on the snap-fit ​​fastener 13. When replacing the blade 11 in the future, it is only necessary to separate the slot 111 on the blade 11 from the pin 131 on the snap-fit ​​fastener 13.

[0050] The pusher 12 may be provided with a sliding groove 121, which corresponds to the blade 11. The blade 11 is embedded in the sliding groove 121 and fits against the pusher 12. At the same time, the pin 131 of the locking fastener 13 passes through the slot 111 of the blade 11 and fits against the pusher 12, improving the connection stability between the locking fastener 13, the blade 11 and the pusher 12. The sliding groove 121 can also separate the blade 11 from other components in the flashlight body 3 and the upper housing 2, preventing damage to other components during the pushing process of the blade 11.

[0051] To facilitate the replacement of the blade 11, the locking fastener 13 and the pushing member 12 are detachably connected. Specifically, the locking fastener 13 has a through hole, and the pushing member 12 has a protrusion corresponding to the through hole. The protrusion on the pushing member 12 is located between the blade 11 and the fixing groove 122, allowing the blade 11 to abut against the pushing member 12 by passing the pin 131 through the slot 111 on the blade 11, thus improving the connection stability. Furthermore, pushing the button 22 can fully expose the locking fastener 13 and the protrusion, making it easy to remove the locking fastener 13 for blade 11 replacement.

[0052] Furthermore, the surface of the push button 22 is provided with a friction surface 222 with anti-slip texture, which increases the friction between the user's hand and the push button 22, making it easier to move the push button 22.

[0053] Reference Figure 3 In some embodiments, the flashlight body 3 is further provided with a control circuit board 41 and an adjustment assembly 42. The control circuit board 41 is provided with a plurality of light source adjustment points 416 and a power switch point 418. The side of the flashlight body 3 is provided with a switch 424 and an adjustment fixing member 421. The adjustment fixing member 421 is provided with an adjustment key 423 and a first opening 4212. The adjustment key 423 is located in the first opening 4212 and moves along the first opening 4212. The switch 424 is connected to the power switch 4212. The power switch point 418 corresponds to the light source switch point 418. When the power switch 424 is pressed, the power switch point 418 is triggered, adjusting the switch of the light source group 43. Several locking grooves 4211 are provided on the first opening 4212, each corresponding to a light source adjustment point 416. When the adjustment key 423 slides to engage with a locking groove 4211, the adjustment key 423 abuts against the corresponding light source adjustment point 416, triggering the control circuit board 41 to adjust the brightness of the light source group 43. Specifically, the control component 4 includes the aforementioned control circuit board 41 and adjustment component 42.

[0054] The first opening 4212 is located on the side of the flashlight body 3, and can be distinguished from the push button 22 located in the movable slide 21 to prevent accidental button presses. By pressing the power switch 424, the power switch point 418 can be triggered, thereby controlling the opening and closing of the light source group 43 through the control circuit board 41; by sliding the adjustment key 423 to reach the position of any locking groove 4211, the corresponding light source adjustment point 416 can be triggered, thereby adjusting the brightness of the light source group 43 through the control circuit board 41.

[0055] Furthermore, the adjustment key 423 is provided with a contact 4231 and a spring-loaded engaging member 4232. The adjustment key 423 contacts the light source adjustment point 416 through the contact 4231; the adjustment key 423 engages with the engaging groove 4211 through the spring-loaded engaging member 4232; the switch 424 includes an output protrusion 4244, a buffer spring 4242, and an abutment 4243. The buffer spring 4242 is sleeved on the output protrusion 4244 and is located between the output protrusion 4244 and the abutment 4243; the switch 424 contacts the power switch point 418 through the abutment 4243. The control circuit board 41 is also provided with several indicator lights 417, which are electrically connected to the corresponding light source adjustment points 416.

[0056] The elastic engaging component 4232 is an elastic element, specifically a spring with abutment beads at both ends. The adjusting key 423 has a through hole for the abutment beads to pass through, and can be fixed by engaging the abutment beads with the engaging groove 4211, thereby fixing the position of the adjusting key 423. A sealing ring 4241 is also provided between the output protrusion 4244 and the buffer spring 4242 to increase the tightness of the connection between the output protrusion 4244 and the buffer spring 4242.

[0057] Specifically, the control circuit board 41 may also be equipped with an indicator light 417 that is electrically connected to the power switch point 418, so as to make it easy to know the on / off status of the light source group 43 of the flashlight with quick blade replacement; that is, when the power switch point 418 is in contact with the switch 424 and the light source adjustment point 416 is in contact with the contact 4231, the corresponding indicator light 417 will light up, thus serving as a prompt.

[0058] Specifically, to facilitate the adjustment of the brightness of the light source group 43 via the adjustment key 423, an external adjustment key 422 is provided on the adjustment key 423. The surface area of ​​the external adjustment key 422 is larger than that of the adjustment key 423, making it easier for the user to touch and move it. The adjustment key 423 and the external adjustment key 422 are fixedly connected by a third fixing member 4233. Furthermore, the adjustment fixing member 421 is fixedly connected to the control circuit board 41 by a second fixing member 425, which can be a screw, bolt, etc.

[0059] Reference Figure 4 In some embodiments, the quick-change blade flashlight also includes a charging connector 413. The light source assembly 43 and the charging connector 413 are axially arranged at both ends of the control circuit board 41.
