[0031] In order to make the technical problems, technical solutions and beneficial effects of the present application more clearly understood, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0032] Please refer to Figure 1 and Figure 2 The automatic igniting non-electric cutting pen provided by the present application will be described. The automatic igniting non-electric cutting pen comprises a cutting pen body 10, an ignition structure 20 and a plugging piece 30. The cutting pen body 10 has a cutting end. The ignition structure 20 is arranged at the cutting end of the cutting pen body 10. The plugging piece 30 is slidably arranged on the cutting end of the cutting pen body 10 and is arranged correspondingly to the ignition structure 20. The plugging piece 30 can rub and ignite the ignition structure 20 during the process of sliding away from the cutting pen body 10.

[0033] Compared with the prior art, the automatic ignitable electric-free cutting pen provided by the embodiment is characterized in that the sealing member 30 is in sliding connection with the cutting end of the cutting pen body 10 and is arranged in correspondence with the ignition structure 20, the sealing member 30 can ensure waterproof and moisture-proof protection of the cutting end of the cutting pen body 10, and when in use, the sealing member 30 only needs to be slid outward, the sealing member 30 rubs and ignites the ignition structure 20 in the process of being separated from the cutting pen body 10, automatic ignition is realized, convenience is increased, and the automatic ignitable electric-free cutting pen can also cope with extreme or special environments, and has high practicability.

[0034] In some embodiments, the ignition structure 20 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , the ignition structure 20 comprises a high-temperature match 21, and the high-temperature match 21 has a match head 22.

[0035] The high-temperature match 21 is a specially designed match that can be quickly ignited under extreme conditions to generate a high-temperature flame, and can be applied to occasions in the field or in emergency situations to ensure ignition of the cutting machine in the cutting pen body 10 and can also cope with extreme or special environments.

[0036] In some embodiments, the sealing member 30 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , the sealing member 30 comprises a sleeve 31 and an elastic sheet 33. The sleeve 31 is sleeved on the cutting pen body 10, and one end of the sleeve 31 is fixedly provided with a bottom cover 32. The elastic sheet 33 is located in the lumen of the sleeve 31 and is connected with the bottom cover 32, the elastic sheet 33 has a flat part that can contact the match head 22, and the flat part is covered with sandpaper 34.

[0037] The sleeve 31 can ensure sliding connection with the cutting pen body 10, and one end of the sleeve 31 is provided with the bottom cover 32 that seals the lumen, and the sleeve 31 and the bottom cover 32 form a sleeving cavity with an open end. After the sleeve 31 is sleeved on the cutting pen body 10, the bottom cover 32 is close to the cutting end, and the elastic sheet 33 has a certain elasticity to ensure contact with the match head 22, which ensures that the elastic sheet 33 can continuously rub the match head 22 in the process of separating the sleeve 31 from the cutting pen body 10. This structure can ensure protection of the cutting end of the cutting pen body 10 and also realize automatic ignition of the cutting pen body 10, and has high practicability.

[0038] In the embodiment, an annular sealing strip can be arranged on the inner wall of the sleeve 31 to ensure sealing with the cutting pen body 10. In order to ensure continuous contact with the match head 22, the elastic sheet 33 can be arranged at an angle with the axis direction of the sleeve 31, or after being stably installed, the end part of the elastic sheet 33 extends close to the high-temperature match 21.

[0039] It should be noted that during the process of sliding the sleeve 31 away from the cutting pen body 10, the sliding of the sleeve 31 needs to have a certain speed to ensure the ignition effect of the high-temperature fire lighter 21.

[0040] In some embodiments, the above-mentioned elastic sheet 33 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , two elastic sheets 33 are arranged, and the two elastic sheets 33 are respectively located on the two sides of the high-temperature fire lighter 21.

[0041] The setting of one elastic sheet 33 will push the high-temperature fire lighter 21 by its own elasticity, which may cause the high-temperature fire lighter 21 to deform or deflect under force, and further cause the sandpaper 34 to fail to continuously contact the match head 22. The two elastic sheets 33 arranged on the two sides of the high-temperature fire lighter 21 can ensure that the two elastic sheets 33 will approach to the middle after stable installation, and jointly clamp the high-temperature fire lighter 21, balance the force of the high-temperature fire lighter 21, and further increase the friction surface to further improve the ignition effect of the match head 22.

[0042] In some embodiments, the above-mentioned high-temperature fire lighter 21 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , the high-temperature fire lighter 21 is arranged in line with the central axis of the cutting pen body 10.

[0043] This structure can facilitate the installation of the plugging piece 30, and also facilitate the correspondence with the two elastic sheets 33.

[0044] In some embodiments, the above-mentioned plugging piece 30 can adopt the structure as shown in Figure 2 , Figure 3 i.e. Figure 5 . Referring to Figure 2 , Figure 3 i.e. Figure 5 , one end of each elastic sheet 33 is hinged to the bottom cover 32, an auxiliary rod 35 is fixedly arranged on the hinged end of each elastic sheet 33, and the included angle between the auxiliary rod 35 and the elastic sheet 33 is an acute angle. The two auxiliary rods 35 are arranged at intervals.

[0045] The plugging piece 30 further comprises a bolt pull rod 36, the bolt pull rod 36 is arranged along the axis of the sleeve 31, and is threadedly connected with the bottom cover 32. The end of the bolt pull rod 36 located inside the sleeve 31 is provided with a limiting cap 37 corresponding to the two auxiliary rods 35. The bolt pull rod 36 can pull the two auxiliary rods 35 after the sleeve 31 is sleeved on the cutting pen body 10, so that the two elastic sheets 33 are relatively turned to the plane part in contact with the match head 22.

[0046] In the process of sleeving the sleeve 31 to the cutting pen body 10, the extending ends of the two elastic sheets 33 are in contact, and interference with the high-temperature ignition match 21 occurs during movement, which causes the high-temperature ignition match 21 to be unable to be assembled or to be inconveniently assembled.

[0047] Therefore, one end of each elastic sheet 33 is hingedly connected to the bottom cover 32 (a hinge part can be arranged on the bottom cover 32), and the hinge shaft is arranged in parallel with the plate surface of the bottom cover 32. The other end of the elastic sheet 33 extends outwards. An auxiliary rod 35 is arranged on the hinged end of each elastic sheet 33, and the other end of the auxiliary rod 35 extends towards the other elastic sheet 33. The two auxiliary rods 35 are arranged in a staggered manner, and a gap is formed between the two auxiliary rods 35 for the bolt pull rod 36 to pass through. The bolt pull rod 36 passes through the limiting cap 37 and simultaneously abuts against the two auxiliary rods 35. During movement of the bolt pull rod 36 and the limiting cap 37 towards the bottom cover 32, the bolt pull rod 36 pulls the two auxiliary rods 35, and the two auxiliary rods 35 drive the two elastic sheets 33 to relatively rotate and clamp the high-temperature ignition match 21. In addition, the sandpaper 34 is in contact with the match head 22.

[0048] Specifically, before assembly, the bolt pull rod 36 is loosened, so that the extending directions of the two elastic sheets 33 are arranged along the axial direction of the sleeve 31. After the sleeve 31 is installed, the bolt pull rod 36 is tightened, so that the bolt pull rod 36 drives the two elastic sheets 33 to relatively rotate through the two auxiliary rods 35. For details, see Figure 5 .

[0049] In some embodiments, the above-mentioned plugging member 30 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , the plugging member 30 further comprises a spring 38. The spring 38 is located in the sleeve 31 and is sleeved on the bolt pull rod 36. One end of the spring 38 abuts against the bottom cover 32, and the other end of the spring 38 abuts against the two auxiliary rods 35. The spring 38 is arranged to ensure that, after the bolt pull rod 36 is loosened, the spring 38 drives the two auxiliary rods 35 to relatively rotate, and the two auxiliary rods 35 drive the two elastic sheets 33 to relatively rotate, thereby further ensuring the convenience of assembly.

[0050] In some embodiments, the above-mentioned limiting cap 37 can adopt the structure as shown in Figure 3 and Figure 4 . Referring to Figure 3 and Figure 4 , the limiting cap 37 is provided with two limiting grooves 39 for storing the two auxiliary rods 35.

[0051] In order to avoid the auxiliary rod 35 from being separated from the limiting cap 37, the limiting groove 39 for clamping the auxiliary rod 35 is arranged on the limiting cap 37. At this time, it is necessary to ensure that the limiting cap 37 is rotationally connected to the bolt pull rod 36 to avoid rotation of the limiting cap 37.

[0052] In some embodiments, the cutting pen body 10 can adopt the structure as shown in Figure 1 Referring to Figure 1 , the cutting pen body 10 is provided with a connecting structure 15 detachably connected with the sleeve 31 and fixing the position of the sleeve 31.

[0053] The connecting structure 15 can mainly avoid the accidental disengagement of the plugging member 30 from the cutting pen body 10, and increase the safety. Specifically, the connecting structure 15 can ensure that a fixing block provided on the cutting pen body 10 is provided with a through insertion hole, and a notch for embedding the fixing block is provided on the sleeve 31, and a positioning hole corresponding to the through insertion hole is provided at the notch. After the sleeve 31 is installed and the through insertion hole and the positioning hole are matched, the two can be fixedly connected by the way of the pin passing through. Of course, in order to facilitate the opening of the positioning hole, a fixing plate corresponding to the fixing block can be provided on the sleeve 31.

[0054] In some embodiments, the cutting pen body 10 can adopt the structure as shown in Figure 2 Referring to Figure 2 , the cutting pen body 10 includes a cylindrical shell 11 and a tab 12. The cylindrical shell 11 has a barrel cavity 14 provided with an open end, and the open end of the cylindrical shell 11 is a cutting end. The end of the cylindrical shell 11 away from the open end of the barrel cavity 14 is provided with a hand grip 13. The tab 12 is provided at the open end of the barrel cavity 14 and is fixedly connected with the ignition structure 20. The tab 12 and the barrel cavity 14 form a containing space for storing the non-electric cutting agent.

[0055] The cylindrical shell 11 is provided with the hand grip 13, which can be convenient for the staff to hold. As for the tab 12, that is, the ignition tab, it can be a circular plate-shaped structure, such as a fixed wax block, which can ensure that the open end of the barrel cavity 14 is sealed and is fixedly connected with the high-temperature ignition match 21, which is easy to burn and can provide enough heat to ignite the non-electric cutting agent in a short time under the ignition of the high-temperature ignition match 21.

[0056] The above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
