[0039] In some embodiments, as shown in Figure 1 and Figure 2 The shape of the moving plate 200 can be rectangular. In addition, the shape of the moving plate 200 can be selected according to the actual device or equipment.
[0040] In some embodiments, as shown in Figures 1 to 4 The adjusting assembly 300 is mounted on the moving plate 200 and fixedly connected with the support plate 100, and the moving plate 200 moves horizontally on the support plate 100 through the adjusting assembly 300. The adjusting assembly 300 includes a rotating piece 310 and a limiting pin 320, the rotating piece 310 is rotatably abutted on the mounting surface 220, that is, a part of the rotating piece 310 is abutted on the mounting surface 220, which can limit the freedom of the moving plate 200 in the thickness direction of the support plate 100, so that the moving plate 200 and the support plate 100 are always attached together. The rotating piece 310 is provided with a rotating protrusion 311, the rotating protrusion 311 extends into the first through hole 210, and the rotating protrusion 311 is rotatably matched with the first through hole 210, that is, the rotating protrusion 311 is a part of the rotating piece 310, the rotating protrusion 311 can extend into the first through hole 210, and the rotating protrusion 311 is rotatably matched with the first through hole 210, so that the rotating piece 310 can rotate freely relative to the moving plate 200. The rotating piece 310 is provided with a straight slot hole 312 extending along the thickness direction of the rotating piece 310, and the midpoint of the straight slot hole 312 coincides with the center point of the first through hole 210. The shank 321 of the limiting pin 320 passes through the straight slot hole 312, the shank 321 of the limiting pin 320 is matched with the pin hole 110, the shank 321 of the limiting pin 320 is movable in the straight slot hole 312 along the length direction of the straight slot hole 312, and the head 322 of the limiting pin 320 is abutted on the rotating piece 310, that is, the limiting pin 320 can pass through the straight slot hole 312, and the limiting pin 320 can be mounted in the pin hole 110, so as to limit the freedom of the rotating piece 310 in the thickness direction of the support plate 100, and avoid the rotating piece 310 from falling off the moving plate 200.
[0041] Specifically, the limiting pin 320 can be installed in the pin hole 110, the pin head 322 abuts against the rotating piece 310, and the rotating piece 310 abuts against the moving plate 200, so as to limit the degree of freedom of the moving plate 200 in the thickness direction of the support plate 100, so that the moving plate 200 and the support plate 100 are always attached together. In addition, during the horizontal movement of the moving plate 200, the rotating piece 310 on the moving plate 200 is first subjected to the horizontal extrusion force of the moving plate 200, and at the same time, the rotating piece 310 will generate a horizontal extrusion force on the limiting pin 320, that is, under the joint action of the moving plate 200 and the limiting pin 320, the rotating piece 310 can rotate relative to the moving plate 200, so that the straight direction of the straight slot hole 312 is aligned with the stress direction of the rotating piece 310, so as to facilitate the movement of the limiting pin 320 in the straight slot hole 312, so that the rotating piece 310 can move horizontally relative to the limiting pin 320, that is, the moving plate 200 moves horizontally relative to the support plate 100.
[0042] It should be noted that horizontal movement can be understood as movement of the moving plate 200 relative to the support plate 100 in any direction in the horizontal plane.
[0043] In some embodiments, the shape of the rotating piece 310 can be any shape, as long as a part of the rotating piece 310 abuts against the mounting surface 220 of the moving plate 200 to limit the degree of freedom of the moving plate 200 in the thickness direction of the support plate 100. Preferably, the shape of the rotating piece 310 is circular.
[0044] In some embodiments, as shown in Figures 1 to 4 , the adjusting assembly 300 is four, and the four adjusting assemblies 300 are respectively located at the four corners of the moving plate 200. Specifically, the four adjusting assemblies 300 can position the moving plate 200 to avoid the phenomenon of deviation of the moving plate 200 during movement. In other words, during the movement of the moving plate 200, the four adjusting assemblies 300 are subjected to the same force of the moving plate 200, and the four adjusting assemblies 300 are respectively located at the four corners of the moving plate 200, which can ensure that the moving plate 200 is in a relative movement state relative to the support plate 100, and avoid the relative rotation state of the moving plate 200 relative to the support plate 100.
[0045] In some embodiments, as shown in Figure 1 and Figure 2 , the limiting pin 320 is detachably arranged in the pin hole 110.

The first top screw block 410 is arranged in a spaced manner with the moving plate 200, and a moving space of the moving plate 200 can be reserved to avoid that the first top screw block 410 hinders the moving plate 200 from moving. The first top screw block 410a is provided with a first top screw hole 411a extending in a first direction, and the first top screw 420a passes through the first top screw hole 411a and can abut against the moving plate 200 to push the moving plate 200. Specifically, by adjusting the position of the first top screw 420a on the first top screw block 410a, the first top screw 420a can push the moving plate 200 in the first direction, so that the moving plate 200 moves in the horizontal plane. In addition, by the cooperation of the first top screw 420a and the first top screw block 410a, the first adjusting assembly 400a can output a larger pushing force to push the moving plate 200 and large equipment and devices on the moving plate 200. At the same time, the cooperation of the first top screw 420a and the first top screw block 410a can accurately control the distance by which the first top screw 420a pushes the moving plate 200, so that the position of the vacuum pipe or the solenoid can be accurately controlled, and then it is ensured that the beam can accurately pass through the vacuum pipe or the solenoid.

The first direction is orthogonal to the second direction, the first direction is orthogonal to the thickness direction of the support plate 100, and the second direction is orthogonal to the thickness direction of the support plate 100. Specifically, the second adjusting assembly 400b has the same working principle and technical effects as the first adjusting assembly 400a, and details are not repeated here. It should be noted that the second adjusting assembly 400b adjusts the position of the moving plate 200 in the second direction, and the first adjusting assembly 400a adjusts the position of the moving plate 200 in the first direction.

Under the joint action of the first adjusting assemblies 400a on the left and right sides of the moving plate 200, the left and right positions of the moving plate 200 can be adjusted. At the same time, the two adjusting assemblies 400a simultaneously push the moving plate 200, so that the moving plate 200 can be more uniformly subjected to the force in the first direction, avoiding the relative rotation of the moving plate 200 due to the uneven force caused by the single adjusting assembly 400a pushing the moving plate 200.
[0053] In some embodiments, as shown in Figure 1 and Figure 2 As shown, the second adjusting assembly 400b is four, two of which are arranged on one side of the moving plate 200 in the second direction, and the other two are arranged on the other side of the moving plate 200 in the second direction.
