[0041] The clamping fixing member 13 is used to connect the pushing member 12 and the blade 11. The clamping fixing member 13 is detachably connected to the pushing member 12. Specifically, the pushing member 12 is provided with a first connecting hole 123 for being fixedly connected with the clamping fixing member 13. The clamping fixing member 13 is provided with a protrusion corresponding to the first connecting hole 123. The protrusion is engaged with the first connecting hole 123 to clamp the blade 11 between the clamping fixing member 13 and the pushing member 12. The blade 11 may also be provided with a protrusion corresponding to the first connecting hole 123. The through hole allows the protrusion to pass through the through hole and engage with the first connecting hole 123, thereby achieving the effect of fixing the position of the blade 11; a through hole corresponding to the first connecting hole 123 can also be set on the snap-fit ​​fixing member 13, and a connecting rod corresponding to the first connecting hole 123 is also set. The connecting rod passes through the corresponding through hole on the snap-fit ​​fixing member 13, and / or the corresponding through hole on the blade 11, and the first connecting hole 123 in sequence to fix the blade 11 between the snap-fit ​​fixing member 13 and the pushing member 12. The connecting rod can be a screw, a bolt, etc.

[0042] The driving method of driving the push member 12 to move by the push button 22 on the upper housing 2, and then causing the blade 11 to move accordingly, is simple and easy to operate, and the length of the exposed blade 11 can be controlled according to the pushing force, which is convenient for the user. After the blade 11 is completely pushed out or the clamping fixture 13 is pushed out, the blade 11 can be replaced. Specifically, after the connection between the blade 11 and the clamping fixture 13 is exposed, the blade 11 can be taken out for replacement. This replacement method is simple and flexible, and does not require the use of other tools.

[0043] The light source group 43 and the cutter assembly 1 can be arranged at the same end of the flashlight body 3, or the light source group 43 and the cutter assembly 1 can be axially arranged at two ends of the flashlight body 3; they can be arranged according to the user's habits or needs to improve the user's experience; the light source group 43 and the cutter assembly 1 are preferably located at the same end of the flashlight body 3, which is convenient for switching functions or combined use in dark environments.

[0044] In some embodiments, a control component 4 is further provided on the flashlight body 3 , and the control component 4 is electrically connected to the power component 5 ; the light source group 43 is electrically connected to the control component 4 , and is electrically connected to the power component 5 through the control component 4 .

[0045] In some embodiments, a movable slide groove 21 is provided on the upper shell 2 ; the tool assembly 1 is located in the movable slide groove 21 , and the push button 22 pushes the tool assembly 1 to move along the movable slide groove 21 .

[0046] Combined with reference Figure 2 Furthermore, a plurality of locking grooves 211 are provided on the inner side of the movable slide groove 21, and the push button 22 passes through the movable slide groove 21 to be connected to the push member 12. The push button 22 is provided with a locking protrusion 221; the locking groove 211 is used to be engaged and fixed with the locking protrusion 221. Specifically, the push button 22 is located in the movable slide groove 21, and passes through the movable slide groove 21 to be connected to the push member 12.

[0047] The locking groove 211 and the locking protrusion 221 can be engaged and fixed, thereby locking the position of the push button 22. In the locked state, the blade 11 cannot move, and the locking groove 211 and the locking protrusion 221 can achieve the effect of locking the blade 11; therefore, when the blade 11 is not needed, the blade 11 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 being exposed and causing harm to the user; when the blade 11 is needed to be used, the blade 11 is exposed to a certain length and then locked, which can also prevent the blade 11 from being unfixed and causing 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 an unlocked state, which is convenient for replacing the blade 11. Specifically, the number of locking grooves 211 can be set according to actual needs.

[0048] 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 locking groove 211 and the locking protrusion 221 are engaged and fixed by the pressing spring 14.

The locking protrusion 221 is in contact with the fixing groove 122 in the axial direction through the pressing spring 14, and is directly engaged with the locking groove 211 in the horizontal direction, thereby fixing the position of the push button 22 on the movable slide groove 21.

[0050] In the unlocked state, the pressing spring 14 is always in a compressed state, and the push button 22 can move along the movable slide groove 21; when the push button 22 reaches any locking groove, the locking protrusion 221 is inserted into the locking groove 211, and the elastic restoring force of the pressing spring 14 is used to ensure that the locking protrusion 221 and the locking groove 211 are tightly engaged, thereby achieving the effect of 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.

[0051] Furthermore, the blade 11 is provided with a slot 111, and the clamping fixture 13 is provided with a latch 131 corresponding to the slot 111, and the latch 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 through the slot 111 on the blade 11 and the latch 131 on the clamping fixture 13; when the blade 11 is replaced later, it is only necessary to separate the slot 111 on the blade 11 from the latch 131 on the clamping fixture 13.

[0052] The pusher 12 may be provided with a sliding groove 121, which is provided corresponding to the blade 11. The blade 11 is embedded in the sliding groove 121 and fits with the pusher 12. At the same time, the latch 131 of the clamping fixture 13 passes through the slot 111 of the blade 11 and fits with the pusher 12, thereby improving the connection stability between the clamping fixture 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 shell 2, thereby preventing the blade 11 from damaging other components during the pushing process.

[0053] In order to facilitate the replacement of the blade 11, the clamping fixing member 13 and the pushing member 12 are detachably connected; specifically, a through hole is provided on the clamping fixing member 13, and a protrusion corresponding to the through hole is provided on the pushing member 12. The protrusion on the pushing member 12 is located between the blade 11 and the fixing groove 122, and the blade 11 can be abutted against the pushing member 12 by passing the plug 131 through the slot 111 on the blade 11, thereby improving the connection stability; and the clamping fixing member 13 and the protrusion can be completely exposed by pushing the button 22, so that the clamping fixing member 13 can be removed conveniently to replace the blade 11.
