[0155] Please see again Figure 4 , Figure 7 and Figure 8 As shown, one end of the second sliding portion 214 is arranged with a thread matching the first threaded portion 212 , and one end of the third sliding portion 215 is arranged with a thread matching the second threaded portion 213 .

[0156] The working principle of this embodiment is as follows:

[0157] See also Figures 1 to 4 As shown, the clamp consists of an adjusting member 1 and a clamp body 2, the clamp body 2 is used to clamp parts, and the adjusting member 1 is used to adjust the flatness of the clamp body 2. It should be noted that the clamp body 2 can be replaced according to the parts to be clamped, wherein a plurality of seventh mounting holes are arranged on the adjusting member 1, and the clamp body 2 is provided with mounting holes matching the seventh mounting holes 114. At this time, the clamp body 2 and the adjusting member 1 are installed by a plurality of fourth fasteners 115.

[0158] Among them, the adjusting member 1 is composed of a fixed member 101 and a movable member 102. The fixed member 101 is a rectangular body with handles on both sides for easy picking. The fixed member 101 remains stationary when the clamp body 2 is working, and the adjustment of flatness is mainly completed by the movable member 102. An elastic member 103 and a joint ball 104 are installed between the fixed member 101 and the movable member 102. The principle of determining a plane based on three points is adopted, wherein the joint ball 104 is a fulcrum, and the height of the movable member 102 is controlled by adjusting the compression amount of the two elastic members 103. It should be noted that the elastic member 103 and the joint ball 104 are respectively fixed by fasteners.

[0159] See also Figure 7 and Figure 8 After installing the clamp body 2, adjust the flatness, wherein the second mounting portion 207 is connected to the seventh mounting hole 114, the second mounting portion 207 is in a rectangular shape, and is provided with a plurality of mounting holes matching the seventh mounting hole 114, and the two are mounted by fasteners. In fact, the second connecting portion 208 and the second mounting portion 207 are integrally formed, and the second connecting portion 208 is in the shape of a groove, in which an adjusting portion 209 is arranged, wherein the adjusting portion 209 is composed of an adjusting handle 211 and an adjusting portion body 210, and the adjusting portion body 210 is arranged with a first threaded portion 212 and a second threaded portion 213 whose thread is opposite to the first threaded portion 212. Accordingly, the first threaded portion 212 is threadedly connected to a second sliding portion 214 that matches it, and the second threaded portion 213 is threadedly connected to a third sliding portion 215 that matches it, wherein the thread at one end of the third sliding portion 215 is opposite to the thread at one end of the second sliding portion 214, so as to satisfy that when the adjusting handle 211 is rotated, the third sliding portion 215 and the second sliding portion 214 slide relative to each other, and when the adjusting handle 211 is reversed, the third sliding portion 215 and the second sliding portion 214 slide oppositely.
