[0030] In order to better explain the present utility model for easy understanding, the following will describe the present utility model in detail through specific embodiments in conjunction with the drawings.

[0031] It should be noted that all the directional indications in the embodiments of the present utility model are only used to explain the relative positional relationship, movement conditions, etc. between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0032] In addition, in the present utility model, descriptions such as "first" and "second" are only for descriptive purposes, and cannot be understood as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present utility model, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0033] In the present utility model, unless otherwise clearly specified and defined, terms such as "connection" and "fixation" shall be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly defined. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0034] The present utility model provides a cantilever bracket, as Figure 1 and Figure 2 shown, which includes a mounting base 10. The mounting base 10 is fixedly arranged. An adjusting block 11 is rotatably mounted on the mounting base 10. A connecting rod 12 is mounted on the adjusting block 11. Two connecting blocks 20 with end faces rotatably arranged are mounted on the connecting rod 12. The connecting rod 12 is connected to one of the connecting blocks 20. An operating rod 21 is mounted on the other connecting block 20. A clamp is mounted on the operating rod 21, and the clamp is used to hold the tool to be operated.

[0035] In this embodiment, rotating the mounting base 11 can make the connecting rod 12 rotate in the first direction, and rotating the connecting block 20 connected to the operating rod 21 can make the operating rod 21 rotate in the second direction. In order to facilitate adjusting the position of the clamp, an angle adjusting device is provided between the mounting base 10 and the end faces of the adjusting block 11 and the two connecting blocks 20. Under the action of the angle adjusting device, the position of the connecting rod 12 in the first direction and the position of the operating rod 21 in the second direction can be fixed.

[0036] As Figure 2 and Figure 4As shown, the angle adjustment device includes a gear ring 30. Specifically, gear rings 30 are installed on the mounting base 10, the adjustment block 11, and the connecting block 20. The gear rings 30 between the mounting base 10 and the adjustment block 11 mesh with each other, and the gear rings 30 on the two connecting blocks 20 mesh with each other, locking them in the circumferential direction to prevent self-rotation. During the process of adjusting the angle, the two meshing gear rings 30 can be separated to freely rotate, achieving angle adjustment.

[0037] As Figure 2 and Figure 3 shown, in this embodiment, the mounting base 10 is fixed to the installed component by bolts 13. A first through hole 14 penetrating one side surface is provided on the adjustment block 11. The connecting rod 11 is inserted into the first through hole 14. A first screw rod 15 perpendicular to the opening direction of the first through hole 14 is inserted through the adjustment block 11. The first screw rod 15 passes through the first through hole 14. A first nut 16 is installed at the position corresponding to the first screw rod 15 on the outer side surface of the adjustment block 11. The first screw rod 15 is threadedly connected to the first nut 16.

[0038] Specifically, during use, after inserting the connecting rod 11 into the first through hole 14, rotate the first screw rod 15. The first nut 16 moves on the first screw rod 15, squeezing the adjustment block 11. The adjustment block 11 deforms, slowly reducing the first through hole 14, thereby pressing the connecting rod 11 tightly to prevent it from sliding out on its own. For some circular connecting rods 11, a fitting plane can be provided in the connecting rod 11 and the first through hole 14 to prevent the connecting rod 11 from rotating around its own axis.

[0039] In this embodiment, a cap screw 17 is inserted through the adjustment block 11 corresponding to the center of the gear ring 30. The cap screw 17 is threadedly connected to the mounting base 10, and a first spring 18 is sleeved on the cap screw 17. The first spring 18 has a tendency to separate the mounting base 10 and the adjustment block 11.

[0040] During the use of this device, loosen the cap screw 17. Under the action of the first spring 18, the mounting base 10 and the adjustment block 11 are separated, and the meshing gear rings 30 are also separated. At this time, the adjustment block 11 can be rotated to rotate in the first direction, thereby adjusting the position of the connecting rod 11. After the position is adjusted, tighten the cap screw 17. At this time, the first spring 18 is compressed, the mounting base 10 and the adjustment block 11 are re - attached, and the corresponding gear rings 30 are re - meshed, thus fixing the adjustment block 11.

[0041] As Figure 1 、 Figure 4 and Figure 5As shown in the figure, second through holes 22 penetrating one side surface are formed in both of the two connecting blocks 20. The connecting rod 11 and the operating block 21 are respectively inserted into the second through holes 22 in the connecting blocks 20 in contact therewith. A second screw rod 23 perpendicular to the opening direction of the second through hole 22 is inserted through the connecting block 20. The second screw rod 23 passes through the corresponding second through hole 22. A second nut 24 is installed at a position corresponding to the second screw rod 23 on the connecting block 20. The second screw rod 23 is threadedly connected to the second nut 24. By rotating the second screw rod 23, the second nut 24 moves on the second screw rod 23, squeezing the connecting block 20. Deformation of the connecting block 20 can reduce the second through hole 22, thereby clamping the connecting rod 11 and the operating rod 21 to prevent them from sliding out by themselves. At the same time, in order to prevent the connecting rod 11 and the operating rod 21 from rotating around their own axes, a plane fitting the connecting rod 11 and the operating rod 21 can be formed in the second through hole 22, thereby preventing the connecting rod 11 and the operating rod 21 from rotating around their axes.

[0042] In order to facilitate adjustment of the position of the operating rod 21, in this embodiment, a second spring 25 is provided on the end faces of the two connecting blocks 20 in contact. The second spring 25 makes the two connecting blocks 20 press against each other tightly. In order to make the device operate more stably, a sleeve 26 is provided between the end faces of the two connecting blocks 20. The connecting block 20 is inserted and matched with the sleeve 26, and the second spring 25 is arranged at the center of the sleeve 26.

[0043] During the process of adjusting the angle of the connecting block 20, by fixing one of the connecting blocks 20 and pulling the other connecting block 20 apart, preferably pulling the connecting block 20 connected to the operating rod 21, at this time the second spring 25 is stretched, and the meshed gear rings 30 are also separated. At the same time, the sleeve 26 also ensures that the two connecting blocks 20 remain coaxial. Then rotate the connecting block 20 to rotate the operating rod 21 in the second direction. After the angle is adjusted, release the connecting block 20. At this time, under the action of the second spring 25, the two connecting blocks 20 press against each other again, and the corresponding gear rings 30 are meshed again to fix the position of the operating rod 21.

[0044] In this embodiment, in order to facilitate assembly, insertion rods 27 are inserted through both of the connecting blocks 20. Hooks are provided at both ends of the second spring 25. Hanging the hooks on the insertion rods 27 can install the second spring 25 between the two connecting blocks 20.

[0045] As Figure 8 shown, after the operating rod 21 is rotated in the second direction, it can be parallel to the connecting rod 12, thereby achieving the effect of storage.

[0046] A welding device, as Figure 1 、 Figure 6 and Figure 7As shown, it includes the cantilever bracket as described above. The fixture includes a mutually cooperating upper clamp cover 41 and a lower clamp cover 42. An electric soldering iron 43 is arranged between the upper clamp cover 41 and the lower clamp cover 42. First grooves 44 are provided at positions corresponding to the electric soldering iron 43 on both the upper clamp cover 41 and the lower clamp cover 42. When the upper and lower clamp covers are closed, the two first grooves 44 clamp the electric soldering iron 43. A third screw 45 passing through the upper clamp cover 41 and the lower clamp cover 42 is arranged on the fixture. The third screw 45 is perpendicular to the extension direction of the first groove 44. The third screw 45 is threadedly connected to the upper clamp cover 41 or the lower clamp cover 42, and a third spring 46 is sleeved on the third screw 45. The third spring 46 has a tendency to separate the upper clamp cover 41 and the lower clamp cover 42.

[0047] During use, loosen the third screw 45, and under the action of the third spring 46, the upper clamp cover 41 and the lower clamp cover 42 can be separated, facilitating the disassembly and assembly of the electric soldering iron 43.

[0048] In the embodiment, the operating rod 21 is passed through the fixture. Specifically, second grooves 47 are provided at positions corresponding to the operating rod 21 on the clamp cover 41 and the lower clamp cover 42. When the two second grooves 47 are closed, the operating rod 21 can be clamped. To make the installation of the device more stable, a fourth screw 48 is passed through at a position corresponding to the operating rod 21 on the clamp cover 41 or the lower clamp cover 42. The fourth screw 48 passes through the side of the operating rod 21 and is threadedly connected.

[0049] In this embodiment, the fourth screw 48 is preferably passed through the clamp cover that is threadedly connected to the third screw 4.
