In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0012] like Figure 1 As shown in this embodiment, a pistol-type attachment structure for a welding torch handle includes a welding torch handle 1 and an attachment grip 2. The welding torch handle 1 is detachably disposed in the upper opening of the attachment grip 2, and the welding torch handle 1 has an original trigger 3. Specifically, the welding torch handle 1 can be engaged with the upper opening of the attachment grip 2 by means of a locking protrusion and a locking groove, or it can be clamped and fixed by means of the upper opening of the attachment grip 2. The attachment grip 2 is provided with an attachment trigger 4, a trigger return mechanism, and a welding torch handle limiting mechanism. One side of the attachment trigger 4 can push the original trigger 3. The attachment trigger 4 can directly push the original trigger 3 or has a protrusion fixed for pushing the original trigger 3. When the attachment trigger 4 is pressed inward, the attachment trigger 4 pushes the original trigger 3. When the attachment trigger 4 is released, the attachment trigger 4 moves outward, and the original trigger 3 moves outward at the same time, and the welding torch is closed.
[0013] The trigger return mechanism includes a lever plate 5 and a first elastic element 6. One end of the lever plate 5 is hinged in the auxiliary grip 2 and the other end is fixed to the auxiliary trigger 4. The first elastic element 6 drives the lever plate 5 to push the auxiliary trigger 4 out of the auxiliary grip 2. The first elastic element 6 is a compression spring. The auxiliary grip 2 is provided with a compression spring mounting ring 7 corresponding to the first elastic element 6. One end of the compression spring is inserted into the compression spring mounting ring 7. The lever plate is provided with a compression spring insert 8 corresponding to the first elastic element 6. The compression spring insert 8 is inserted into the other end of the compression spring. The compression spring insert 8 and the compression spring mounting ring 7 cooperate to fix the compression spring and maintain its normal working position.
[0014] The welding torch handle limiting mechanism includes a hook plate 9 and a second elastic element 10. The welding torch handle 1 is provided with a slot that mates with the upper end of the hook plate 9. The middle part of the hook plate 9 is hinged in the auxiliary grip 2. The second elastic element 10 is close to the lower end of the hook plate 9. The second elastic element 10 drives the upper end of the hook plate 9 into the slot. The second elastic element 10 is also a compression spring. The auxiliary grip 2 is provided with a compression spring mounting ring 7 corresponding to the second elastic element 10. One end of the compression spring is inserted into the compression spring mounting ring 7. The hook plate 9 is provided with a compression spring insert 8 corresponding to the second elastic element 10. The compression spring insert 8 is inserted into the other end of the compression spring. The compression spring insert 8 and the compression spring mounting ring 7 cooperate to fix the compression spring and maintain its normal working position.
[0015] The auxiliary grip 2 is provided with an operating opening 11 corresponding to the lower part of the hook plate 9. The lower part of the hook plate 9 can be pressed inward through the operating opening 11 to release the engagement between the hook plate 9 and the slot on the welding gun handle 1, allowing the welding gun handle 1 to be separated from the auxiliary grip 2.
[0016] The working principle of this embodiment is as follows: The auxiliary grip 2 is installed below the original trigger 3 of the welding torch handle 1. The hook plate 9 and the slot are well matched. When the welding torch needs to be turned on, hold the auxiliary grip 2 and press the auxiliary trigger 4 inward. The auxiliary trigger 4 moves inward and pushes the original trigger 3 to retract, and the welding torch is turned on. When the welding torch needs to be turned off, release the auxiliary trigger 4. Under the action of the first elastic element 6, the auxiliary trigger 4 moves outward. The original trigger 3 also extends under the action of its own assembly mechanism with the welding torch handle 1, and the welding torch is turned off. Compared with the prior art, this embodiment can be combined to form a pistol-type structure. Welding can be easily operated by the auxiliary grip 2 and the auxiliary trigger 4. Compared with the traditional straight grip welding torch handle, this embodiment has the advantages of reliable structure, easy and labor-saving use, and convenient and simple disassembly and assembly, and is suitable for widespread use.
[0017] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
