[0034] The present embodiment provides a clamp, as shown in Figure 1 and Figure 2 , which comprises a base plate 10, a support assembly 20, and a clamping mechanism 30. Among them, the base plate 10 is arranged at a predetermined work station; the support assembly 20 is rotatably connected to the base plate 10 and can rotate in multiple directions; the clamping mechanism 30 comprises a first clamping piece 31, a second clamping piece 32, and an adjusting assembly 33, the first clamping piece 31 is arranged at one end of the support assembly 20 away from the base plate 10, the second clamping piece 32 is connected with the first clamping piece 31, and an opening 34 is formed between the first clamping piece 31 and the second clamping piece 32, the adjusting assembly 33 can adjust the opening degree of the opening 34, so as to clamp workpieces 100 of different sizes.

[0035] When using this clamp, the base plate 10 can ensure the stability of the entire clamp, the support assembly 20 can drive the clamping mechanism 30 to rotate in multiple directions, so as to improve the clamping mechanism 30 to clamp the workpiece 100 to adjust multiple angles, effectively release the operator's need to hold the soldering iron arm, not only improve the safety of operation, also will not appear in the welding process due to the operator's fatigue and shaking, so as to improve the welding precision and welding efficiency; finally, the adjusting assembly 33 can also adjust the opening degree of the opening 34, so that the first clamping piece 31 and the second clamping piece 32 can smoothly clamp workpieces 100 of different sizes, improve the use range of the clamp.

[0036] It should be noted that in the present embodiment, as shown in Figure 1 and Figure 2 , the workpiece 100 is an electric soldering iron, and the outer contour of the electric soldering iron is circular. Therefore, the first clamping piece 31 and the second clamping piece 32 are both provided with arc-shaped grooves 35, and the two arc-shaped grooves 35 are oppositely arranged to form the opening 34. This arrangement can make the shape of the opening 34 exactly match the outer contour of the electric soldering iron, thereby improving the clamping effect and ensuring the safety and stability during welding. In other embodiments, the shape of the opening 34 can be adjusted according to the actual shape of the electric soldering iron.

[0037] Further, in order to improve the stability of the base plate 10, as shown in Figure 2As shown in the drawings, the side of the base plate 10 away from the support assembly 20 is provided with a non-slip pad 40. By providing the non-slip pad 40, the friction between the base plate 10 and the predetermined work station can be increased, thereby further improving stability during welding and ensuring the safety of welding. In addition, in the present embodiment, a plurality of non-slip pads 40 are provided, and the plurality of non-slip pads 40 are uniformly arranged along the circumference of the base plate 10.

As long as the safety and stability of the welding process can be ensured, the welding quality and welding efficiency can be ensured, and the present embodiment is not limited otherwise.

[0038] Specifically, as shown in the drawings, Figure 1 and Figure 2 The support assembly 20 includes a first support 21 and a second support 22 connected to each other, the second support 22 is connected with the first clamping piece 31, and the second support 22 can rotate around the connection position with the first support 21. In this structure, the first support 21 and the second support 22 can further increase the length of the support assembly 20, thereby expanding the extension range of the electric soldering iron; in addition, the second support 22 can also rotate around the connection position with the first support 21, which further increases the movement range of the clamping mechanism 30, so that the electric soldering iron can reach more positions, thereby effectively reducing the welding difficulty, ensuring the convenience and precision of welding.

[0039] As shown in the drawings, Figure 1 and Figure 2 The first support 21 and the second support 22 are connected by a ball joint. The connection mode of the ball joint can expand the rotation angle of the second support 22, and has good carrying capacity, good damping effect, and stable rotation process. It should be noted that in the present embodiment, one end of the first support 21 is provided with a first ball head 211, one end of the second support 22 is provided with a second ball head 221, the rotating shaft 23 passes through the first ball head 211 and the second ball head 221 at the same time, and is locked at the other end by the locking piece 24 to avoid falling off. In this structure, the second support 22 can rotate 360 degrees around the connection position with the first support 21, thereby enabling the electric soldering iron to meet the needs of various welding angles, greatly improving the applicability of the clamp.

[0040] It should be noted that the first support 21 and the second support 22 are connected by a ball joint, and the second support 22 can not only rotate at multiple angles, but also hover at a certain specific angle to ensure that the clamping mechanism 30 will not drive the second support 22 to rotate under the action of gravity, thereby ensuring the smooth progress of the welding work.

[0041] In addition, the first support 21 and the second support 22 are detachably connected. The locking member 24 is removed and the rotating shaft 23 is taken out, so that the first support 21 and the second support 22 can be detached. Such a setting not only facilitates installation, but also facilitates subsequent maintenance and replacement of the first ball head 211 and the second ball head 221.

[0042] To improve the convenience of changing the opening 34, as shown in Figure 1 and Figure 2 , the second clamping member 32 is pivotally connected with the first clamping member 31; the adjusting assembly 33 includes an adjusting rod 331, which sequentially passes through the second clamping member 32 and the first clamping member 31, and the adjusting rod 331 is configured to drive the second clamping member 32 to rotate to adjust the opening degree of the opening 34. First, since the second clamping member 32 is pivotally connected with the first clamping member 31, the fluency of changing the opening degree of the opening 34 is improved. Moreover, the adjusting rod 331 can improve the convenience of changing the opening degree of the opening 34.

[0043] Specifically, the adjusting rod 331 includes a first body and a second body connected with each other, wherein the diameter of the first body is larger than that of the second body, the second body can sequentially pass through the second clamping member 32 and the first clamping member 31, and the first body can abut to the outer wall of the second clamping member 32. When the adjusting rod 331 is screwed in the direction close to the second clamping member 32, the first body can abut and push the second clamping member 32 to rotate in the direction close to the first clamping member 31, so as to reduce the opening degree of the opening 34.

[0044] Specifically, as shown in Figure 1 and Figure 2 , the adjusting assembly 33 further includes a rotating rod 332 arranged at the other end of the adjusting rod 331. When it is needed to change the opening degree of the opening 34, the rotating rod 332 can be rotated to indirectly push the adjusting rod 331 to move, and then the adjusting rod 331 can push the second clamping member 32 to reduce the opening degree of the opening 34, so as to clamp an electric solder with a smaller size.

[0045] To make the adjusting process more convenient, as shown in Figure 1 and Figure 2 , the adjusting rod 331 is provided with a plurality of adjusting grooves 3311 arranged at intervals, and the rotating rod 332 is provided with a plurality of adjusting protrusions 3321 arranged at intervals. When it is needed to change the opening degree of the opening 34, the rotating rod 332 can be rotated to push the adjusting rod 331 to move, and then the adjusting rod 331 can push the second clamping member 32 to reduce the opening degree of the opening 34, so as to clamp an electric solder with a smaller size.As shown, the adjusting rod 331 is provided with a through hole 3311, the rotating rod 332 is arranged in the through hole 3311 and can move in the through hole 3311, both ends of the rotating rod 332 are provided with an end cap 3321, and the diameter of the end cap 3321 is greater than the diameter of the through hole 3311. In this structure, the operator can rotate the adjusting rod 331 by holding one end of the rotating rod 332 which naturally droops under the action of gravity, and after rotating a certain angle, the rotating rod 332 is released. Since it can move in the through hole 3311, after releasing the end held, the rotating rod 332 can fall under the action of gravity, and the end of the rotating rod 332 is provided with an end cap 3321, and the diameter of the end cap 3321 is greater than the diameter of the through hole 3311, so that the end cap 3321 can suspend the rotating rod 332, and the other end naturally droops. At this time, the operator can continue to rotate by holding the other end, and so on, until the opening 34 is adjusted to the target opening. The structure is simple, and the operation is convenient, which can effectively improve the clamping and working efficiency.

[0046] The working process of the clamp in the embodiment will be described with reference to the drawings.

[0047] Firstly, the bottom disc 10 is arranged at a preset station, and since the anti-skid pad 40 is arranged, the operator does not need to hold it, the safety of operation is improved, and the stability and welding precision in the welding process are ensured.

[0048] Secondly, the adjusting support assembly 20 is adjusted, so that the first support 21 and the second support 22 are rotated to a target angle, so that the convenience of welding is ensured, and the welding efficiency is improved.

[0049] Finally, the opening degree of the opening 34 is adjusted, so that the electric soldering iron of a corresponding size can be clamped smoothly, and the welding task is completed smoothly.

[0050] As described above, the clamp in the embodiment can not only improve the safety of operation, but also reduce the operation difficulty of the operator, and the welding process is stable, so that the welding quality and welding efficiency are effectively improved.
