[0003] The existing blowtorch mainly includes a housing, and a nozzle device, a piezoelectric device, an ignition component, a gas chamber and a gas valve component for adjusting the softness and hardness of the flame are arranged in the housing; when in use, by pressing the ignition component, the gas valve of the gas chamber will be opened under the downward pressure of the ignition component, and at the same time, the ignition component will also gradually compress the trigger end of the piezoelectric device. When the compression stroke of the piezoelectric device reaches the ignition stroke, the piezoelectric device will release high-voltage electric energy and generate an electric spark at the gas outlet of the nozzle device through a lead wire to achieve ignition; during the use process, the gas flow rate sprayed out from the gas outlet of the nozzle device can also be controlled by adjusting the gas valve component, so as to achieve the purpose of adjusting the softness and hardness of the flame.
[0004] In the related art, the spraying angle of some blowtorches usually cannot be adjusted, which causes that in the actual use process, the user can only manually keep the blowtorch in an inclined state before the nozzle can be smoothly aligned with the area to be heated, which brings great inconvenience to the user during the use process, has poor flexibility, and is difficult to meet the user's adjustment requirements for different spraying angles.

[0021] The following further elaborates on this application in conjunction with the accompanying drawings
[0022] The embodiment of this application discloses an angle-adjustable blowtorch
[0023] Refer to Figure 1 、 Figure 2 , the angle-adjustable blowtorch includes a gun body 1 and a nozzle 2 provided at the top of the gun body 1. A connecting pipe 3 is integrally formed at the top of the gun body 1, and the nozzle 2 is rotatably provided outside the connecting pipe 3. A locking disc 4 is coaxially and movably provided on the connecting pipe 3, and the locking disc 4 movably penetrates through the nozzle 2 along the central axis direction of the connecting pipe 3
[0024] As Figure 2 、 Figure 3 shown, the nozzle 2 includes a first outer shell 200 and a second outer shell 201 that are spliced and fixed to each other. The first outer shell 200 and the second outer shell 201 are symmetrically arranged on both sides of the connecting pipe 3. Insertion pieces 202 are integrally formed on the inner side walls of the first outer shell 200 and the second outer shell 201 and face the outer side wall of the connecting pipe 3. Rotation slots 32 are coaxially provided on the outer side wall of the connecting pipe 3 facing the insertion pieces 202, and the insertion pieces 202 are respectively inserted and rotatably provided in the respective opposite rotation slots 32
[0025] As Figure 3 、 Figure 4 shown, a plurality of limit blocks 20 facing the outer side wall of the connecting pipe 3 are integrally formed on the inner side wall of the first outer shell 200. The limit blocks 20 are circumferentially and evenly spaced in a ring around the central axis of the connecting pipe 3. A limit groove 21 is formed between two adjacent limit blocks 20. A clamping block 40 for being clamped in the relative limit groove 21 is integrally formed on the circumferential outer side wall of the locking disc 4, and the shape of the clamping block 40 is adapted to the shape of the limit groove 21
[0026] As Figure 3 、 Figure 4 shown, a plurality of insertion holes 30 facing the locking disc 4 are further provided on the connecting pipe 3, and the insertion holes 30 are circumferentially and evenly spaced around the central axis of the connecting pipe 3 on one side of the connecting pipe 3. A plurality of insertion plates 41 corresponding to the insertion holes 30 one by one are integrally formed on the locking disc 4. The insertion plates 41 are respectively movably inserted into their corresponding insertion holes 30. One end of the insertion plate 41 away from the locking disc 4 is inserted into the connecting pipe 3, and the end of the insertion plate 41 is limited within the connecting pipe 3. Under the limitation of the insertion plate 41, the locking disc 4 slides along the length direction of the central axis of the connecting pipe 3.
[0027] As Figure 3 、 Figure 4 shown, a positioning rod 42 facing the central axis of the connecting pipe 3 is coaxially and fixedly arranged on the locking disc 4. One end of the positioning rod 42 away from the locking disc 4 extends into the connecting pipe 3, and the positioning rod 42 follows the locking disc 4 and is movably inserted through the connecting pipe 3. An elastic reset member 5 is sleeved outside the positioning rod 42 between the inner side wall of the locking disc 4 and the outer side wall of the connecting pipe 3. In this embodiment, the elastic reset member 5 is a spring. One end of the elastic reset member 5 facing the connecting pipe 3 is provided with a pressing piece 43, and the pressing piece 43 is coaxially and movably inserted outside the positioning rod 42.
[0028] As Figure 3 、 Figure 4 shown, the elastic reset member 5 presses the pressing piece 43 against the outer side wall of the connecting pipe 3, and one end of the elastic reset member 5 away from the pressing piece 43 abuts against the inner side wall of the locking disc 4. In the natural state, the elastic reset member 5 is used to push the side of the locking disc 4 away from the connecting pipe 3 out of the first housing 200. At this time, the clamping block 40 will remain in the state of being clamped in the relative limiting groove 21. Through the clamping cooperation between the clamping block 40 and the limiting groove 21, the relative rotation between the nozzle 2 and the connecting pipe 3 can be restricted, so as to lock the nozzle 2.
[0029] As Figure 3 、 Figure 4 shown, a through hole 31 is formed through the connecting pipe 3, and the through hole 31 penetrates the upper and lower side walls of the connecting pipe 3 along the length direction of the gun body 1. The through hole 31 is used for the lead wire and the air pipe arranged in the gun body 1 to smoothly penetrate into the nozzle 2. A blocking ring 44 facing the insertion plate 41 is integrally formed on the inner side wall of the connecting pipe 3. The blocking ring 44 is coaxially arranged with the connecting pipe 3, and the blocking ring 44 is located on the moving path of the insertion plate 41 when it is inserted into the connecting pipe 3. When the locking disc 4 is pressed, the insertion plate 41 is blocked by the blocking ring 44, so as to effectively prevent the insertion plate 41 from squeezing the lead wire and the air pipe inside the connecting pipe 3 during the sliding process, and protect the lead wire and the air pipe.
[0030] The implementation principle is as follows: When it is necessary to adjust the fire-spraying angle of the nozzle 2, by pressing the locking disc 4, the elastic reset member 5 will be gradually compressed at this time. As the clamping block 40 and the limiting groove 21 are separated from each other, the locking of the locking disc 4 can be released. At this time, the nozzle 2 can be rotated around the central axis of the connecting pipe 3. After rotating the fire-spraying angle of the nozzle 2 to an appropriate position, only the external force applied to the locking disc 4 needs to be removed. At this time, the locking disc 4 will automatically reset under the elastic force of the elastic reset member 5, and the clamping block 40 will be clamped again in the relative limiting groove 21. Through the mutual clamping cooperation between the clamping block 40 and the limiting groove 21, the fire-spraying angle of the nozzle 2 can be locked. The adjustment process is convenient, meeting the user's adjustment requirements for different fire-spraying angles and making the use more flexible.
[0031] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
