[0024] As Figure 3 A clamp for joule heat shock method, including base 1, the upper surface of both ends of base 1 has two symmetrically arranged mounting blocks 2, mounting block 2 has first bolt hole, mounting block 2 has lower cover plate 3 and upper cover plate 4 in proper order, lower cover plate 3 and upper cover plate 4 are set with a through slot, base 1 has second bolt hole, bolt 5 passes through through slot, first bolt hole and second bolt hole, so that upper cover plate 4, lower cover plate 3 are fixed in mounting block 2, mounting block 2 is fixed in base 1. In the embodiment, upper cover plate 4 and lower cover plate 3 are provided with a through slot. The use of bolt 5 makes disassembly very convenient, and the setting of through slot makes the clamping position easy to adjust.
[0025] In the embodiment, the upper cover plate 4 and the lower cover plate 3 are provided with two parallel through grooves. The use of the bolt 5 makes the disassembly very convenient, and the through grooves make the clamping position easy to adjust. The provision of the two through grooves makes the clamping more stable and firm.
[0026] In the embodiment, the lower cover plate 3 and the upper cover plate 4 are both composed of copper.
[0027] Embodiment 3
[0028] As Figure 4 A clamp for the method of joule heat impact, comprising a base 1, the upper surface of both ends of the base 1 is provided with two symmetrically arranged mounting blocks 2, the mounting block 2 is provided with a first bolt hole, the mounting block 2 is sequentially provided with a lower cover plate 3 and an upper cover plate 4, the lower cover plate 3 and the upper cover plate 4 are each provided with two parallel through grooves, the base 1 is provided with a second bolt hole, the bolt 5 passes through the through grooves, the first bolt hole and the second bolt hole, so as to fix the upper cover plate 4 and the lower cover plate 3 on the mounting block 2, in the embodiment, the base 1 and the mounting block 2 are integrated.
