Referring to fig. 2 (b), by rotating the rotating sleeve 4, when the rotating sleeve 4 rotates to the locking position L, the first boss 3221 descends along the threaded structure 41, so that the pushing member 32 descends to drive the barrel 21 to descend, and the barrel 21 retracts relative to the casing 1. Referring to fig. 4 (b), when the rotating sleeve 4 rotates to the unlocking position D, the first boss 3221 ascends along the threaded structure 41, so that the pushing member 32 ascends to drive the barrel 21 to ascend, and the barrel 21 extends out relative to the casing 1. Therefore, the igniting gun 100 of the present application does not need to pull the gun barrel 21, thereby reducing the risk of scalding, and at the same time, the retracted gun barrel 21 can reduce the volume of the igniting gun 100, and is convenient to carry.

Illustratively, the thread structure 41 may be provided on an inner or outer wall of the rotating sleeve 4. When the screw structure 41 is provided at the inner wall of the rotating sleeve 4, the pushing member 32 is provided with a first projection 3221 toward the inner wall of the rotating sleeve 4. When the screw structure 41 is provided at the outer wall of the rotating sleeve 4, the pushing member 32 is provided with a first projection 3221 toward the outer wall of the rotating sleeve 4.

Further exemplary, the screw structure 41 may be a screw boss, a screw groove, a screw through groove, or the like, capable of being engaged with the first boss 3221. When the surface of the rotating sleeve 4 is provided with protrusions to form a threaded boss, the first boss 3221 is abutted on the threaded boss to rise. When the surface of the rotating sleeve 4 is concavely formed into a screw groove, the first projection 3221 is extended into the screw groove and ascends along the screw groove. When the wall of the rotary sleeve 4 is grooved to form a thread through groove, the first boss 3221 is penetrated in the thread through groove and ascends along the thread through groove.

Referring to fig. 9 and 10, in some embodiments, the inner wall of the rotating sleeve 4 is provided with a threaded boss. The limiting member 31 includes a limiting portion 311 and a first supporting bar 312 connected to the bottom of the limiting portion 311, and the peripheral wall of the limiting portion 311 encloses to form an accommodating space 313.

Referring to fig. 8, an abutting portion 321 of the pushing member 32 is disposed through the accommodating space 313 and connected to the limiting portion 311, a second supporting bar 322 is movably disposed in the rotating sleeve 4, a first boss 3221 is disposed in a direction of the second supporting bar 322 facing the inner wall of the rotating sleeve 4, and the second supporting bar 322 moves up and down along the height direction of the casing 1 through the first boss 3221. It can be understood that the pushing member 32 is disposed in the accommodating space 313 surrounded by the peripheral wall of the limiting member 31, and the limiting member 31 is disposed in the rotating sleeve 4, so that the space utilization rate of the rotating sleeve 4 can be improved, and the structure is compact. In addition, compare and set up backup pad or support circle shell in spacing portion and butt portion 321 below, set up first support bar 312 and second support bar 322, can further practice thrift the inside space of rotatory sleeve 4, provide more places the space for other spare parts.

Referring to fig. 7 and 8, in some embodiments, a first protruding edge 3113 is disposed on a peripheral wall of the limiting portion 311 towards the second supporting bar 322, the second supporting bar 322 is bent towards the first protruding edge 3113 to form a second boss 3222, and when the rotating sleeve 4 rotates to the unlocking position D, the second supporting bar 322 rises to make the second boss 3222 abut against the first protruding edge 3113. Second boss 3222 can limit excessive lifting of second support bar 322 after abutting first ledge 3113.

Referring to fig. 7 and 8, in some embodiments, the first support bar 312 is provided with a second protruding edge 3121 towards the second support bar 322, and when the rotating sleeve 4 rotates to the locking position L, the second support bar 322 descends to abut against the second protruding edge 3121. After second support bar 322 abuts against second ledge 3121, excessive lowering of second support bar 322 can be restricted.

Referring to fig. 7, in some embodiments, the telescopic device further includes a fixing member 33, the fixing member 33 is connected to the casing 1 and the limiting member 31, and the fixing member 33 and the limiting member 31 together form a guiding slot for enabling the second supporting bar 322 to move up and down. When the first boss 3221 of the pushing member 32 is matched with the threaded structure 41 of the rotating sleeve 4, the threaded structure 41 drives the first boss 3221 to rotate together, and the guide groove is arranged to prevent the first boss 3221 from rotating and only lifting. Illustratively, a guide groove may be formed on the fixing member 33, the limiting member 31 is connected with the fixing member 33 to cover the guide groove, or a guide groove may be formed on the limiting member 31, and the fixing member 33 is connected with the limiting member 31 to cover the guide groove.

Referring to fig. 8 and 10, specifically, a protruding plate 3112 is disposed on a circumferential wall of the limiting portion 311 in a direction towards the first supporting bar 312, the protruding plate 3112 and the circumferential wall of the limiting portion 311 form a first groove 311a, the second supporting bar 322 movably penetrates through the first groove 311a, referring to fig. 7, a second groove 33a is disposed on the fixing member 33 in a direction towards the limiting member 31, the second groove 33a and the first groove 311a are abutted to form a guiding groove, and the second groove 33a is used for avoiding the second supporting bar 322 and the circumferential wall of the limiting portion 311. The raised plates 3112 may separate second support bar 322 from other components, avoiding interference with the lifting motion of second support bar 322 from other components. Since second supporting bar 322 has a certain thickness, the guide groove needs to provide a width through which second supporting bar 322 passes, and the occupation space of limiting member 31 and fixing member 33 can be reduced at the same time by abutting first groove 311a and second groove 33a to form a guide groove in which second supporting bar 322 can be lifted and lowered.

In some embodiments, referring to fig. 7, the bottom of the fixing member 33 protrudes toward the direction of the rotating sleeve 4 to form a first protrusion 331, referring to fig. 13, the top of the rotating sleeve 4 protrudes toward the direction of the fixing member 33 to form a second protrusion 42, and when the rotating sleeve 4 rotates relative to the casing 1, the second protrusion 42 is used to rotate to abut against the first protrusion 331 so as to rotate the rotating sleeve 4 to the unlocking position D and/or the locking position L. The first protrusion 331 of the fixing member 33 cooperates with the second protrusion 42 of the rotating sleeve 4 to enable a user to have better feel when rotating the rotating sleeve 4, so as to further enhance the user experience. When the user wants to operate the rotating sleeve 4 to switch between the locking position L and the unlocking position D, since the second protrusion 42 has a fixed rotation path relative to the first protrusion 331, the second protrusion 42 can rotate to abut against both sides of the first protrusion 331, and the abutting against each other can cause the rotating sleeve 4 to generate an obvious click effect in the rotation process, so that the user can determine whether to rotate in place according to whether the click touch is generated. For example, the first protrusion 331 has opposite first and second sides, and when the rotating sleeve 4 rotates counterclockwise with respect to the casing 1, the second protrusion 42 rotates to abut against the first side and rotates to the locking position L. When the rotating sleeve 4 rotates clockwise toward the opposite casing 1 to bring the second projection 42 into abutment with the second side, it rotates to the unlock position D.

The ignition gun 100 needs to be provided with a safety switch structure to prevent false touch or improve safety during transportation, and the safety of the ignition gun 100 is generally realized by the following structures: the gun body is provided with the button type safety switch, and the button type safety switch can always lock the ignition switch under the condition that no external force is used for stirring, so that the ignition switch cannot act and is ensured. This way of securing requires slotting and additional fittings on the ignition gun 100, damaging the product appearance, being complex in structure, easy to damage and frequent in changing fittings.

Referring to fig. 2, 4 and 6, the ignition gun 100 according to the embodiment of the application can maintain the ignition gun 100 in the off state when not in use without providing a safety switch fitting. In some embodiments, the ignition device further includes a thumb press 22, the thumb press 22 is disposed in the casing 1, the thumb press 22 is an ignition switch of the ignition gun 100, and the thumb press 22 is lowered to turn on the ignition device. The stopper 311 of the stopper 31 is connected to the thumb press 22, and the stopper 311 is sandwiched between the contact 321 and the thumb press 22. Referring to fig. 3 and 5, the press 22 has an opening 221, the abutment portion 321 has a protrusion rib 3211, and the limiting portion 311 has a curved rib 3111 facing the abutment portion 321 and the opening 221. Referring to fig. 3, when the rotating sleeve 4 is rotated to the locking position L, the protruding rib 3211 is lowered to abut against the curved rib 3111, so that the curved rib 3111 protrudes toward one side of the opening 221 and blocks the opening 221, and the press handle 22 is blocked by the curved rib 3111 and cannot be lowered. When an external force is applied to the thumb press 22, the thumb press 22 cannot turn on the ignition device because the thumb press 22 is caught, and the ignition device is maintained in a closed state to realize safety. Referring to fig. 5, when the rotating sleeve 4 rotates to the unlocking position D, the protruding rib 3211 rises to release the curved rib 3111, so that the curved rib 3111 is far away from the opening 221, at this time, the thumb press 22 is not locked and can be lowered by an external force, and the ignition device can be turned on by pressing the thumb press 22. Therefore, the rotating sleeve 4 is rotated to the locking position L to achieve the safety function, accessories are not required to be additionally arranged, the structure of the protruding ribs 3211 and the bending ribs 3111 is simple, the rotating sleeve is arranged inside the casing 1 and is not easy to damage, the appearance of a product is maintained, and the product is more compact and attractive.
