Fig. 6 is a schematic structural diagram of a second clamping jaw of the clamping jaw assembly according to the embodiment of the application, as shown in fig. 6, the second clamping jaw 2 includes a main body portion and a bending portion, and the bending portion is disposed at one end of the main body portion and extends in a direction approaching to the first clamping jaw 1. The second clamping jaw 2 is further provided with a clamping groove 21, and the volume of the clamping groove 21 is larger than that of the clamping piece 3, so that the clamping piece 3 can be accommodated in the clamping groove 21. The top surface of the clamping groove 21 is a 45-degree inclined abutting surface for applying a force to push the clamping piece 3 to rotate; the bottom surface is a first clamping surface 211, the first clamping surface 211 is arranged along the horizontal direction, and when the welding strip is clamped, the first clamping surface 211 can apply upward acting force on the lower surface of the welding strip.

Specifically, when the main body and the bending portion are integrally formed, the second clamping jaw 2 provided with the clamping groove 21 may be prepared by a specific mold, or the clamping groove 21 with a specific shape may be formed by a tapping device after the main body is prepared. When the main body portion is detachably connected with the bending portion, the main body portion and the bending portion can be connected by using an elastic material, so that the bending portion can move along a vertical direction relative to the main body portion, that is, when an acting force is applied to the first clamping surface 211 of the bending portion, the bending portion slightly moves in a direction away from the main body portion, and when the acting force applied to the first clamping surface 211 is removed, the bending portion returns to an initial position.

The shape of the engaging groove 21 may be actually selected according to the shape of the holder 3, for example, the cross sections of the engaging groove 21 and the holder 3 may be trapezoidal, or may have a hemispherical shape, or may have other shapes, so that the engaging groove 21 may accommodate the holder 3, and the first clamping surface 211 and the second clamping surface 321 may apply forces in the up-down direction to the solder strip.

The first clamping surface 211 and the second clamping surface 321 can slightly deform the welding strip in the process of applying an acting force to the welding strip, and if the distance between the first clamping surface 211 and the second clamping surface 321 is too large, the upper surface and the lower surface of the welding strip are not sufficiently stressed in the process of clamping the welding strip, and the welding strip is easy to fall off in the process of clamping the welding strip; if the distance between the first clamping surface 211 and the second clamping surface 321 is too small, the acting force applied to the upper and lower surfaces of the solder strip is too large in the clamping process, so that the deformation of the solder strip is too large, and the solder strip is easy to damage. The distance between the first clamping surface 211 and the second clamping surface 321 can be selected according to practical needs, which is not limited herein.
In the present application, the material of the clamping portion 32 includes an alloy and/or an elastic material, and it should be noted that, when the clamping portion 32 is made of an elastic material, the distance between the first clamping surface 211 and the second clamping surface 321 may be reduced, and in particular, when the clamping jaw assembly clamps the welding strip, the elastic material abuts against the welding strip and applies a pressure to the welding strip, unlike the alloy material, and the elastic material may also deform, so that the distance between the first clamping surface 211 and the second clamping surface 321 may be properly reduced. The material of the clamping portion 32 may be selected according to actual needs, and is not limited herein.
