The adjusting screw 22 is installed on the support bearing. The adjusting handwheel 21 is fixedly installed at the end of the adjusting screw 22 to drive the adjusting screw 22 to rotate forward and backward for adjustment. Then, the upper driving part 3 and the lower driving part 4 are installed with clearance. First, the upper guide post 5 and the lower guide post 5 can be installed on both sides of the support frame respectively. Column 6, then the threaded sleeve 32 and guide sleeve 33 are connected to the drive bracket 31 by bolts. At the same time, the threaded sleeve 32 is screwed onto the adjusting screw 22 through the threaded hole. The guide sleeve 33 slides in contact with the upper guide post 5 and the lower guide post 6 through the guide hole. Finally, the first clamping part 7 and the second clamping part 8 are installed. First, a through hole 34 adapted to the guide screw 72 is opened on the drive bracket 31. During installation, one end of the guide screw 72 passes through the through hole 34 and is connected to the short end of the clamping arm 71. A buffer spring 74 is fitted on the outer circumference of the guide screw 72 to buffer the clamping arm 71. The limiting nut 73 is turned on the guide screw 72 by thread engagement. An opening groove for guiding the clamping arm 71 is opened at the end of the drive bracket 31. The long end of the clamping arm 71 is slidably engaged in the opening groove. Thus, the installation process of this utility model is completed.

[0030] II. In specific operation and use, as per the instruction manual... Figure 1As shown, the operator can adjust the distance between the first clamping part 7 and the second clamping part 8 according to the thickness of the insulation board. Specifically, the adjusting handwheel 21 can be rotated counterclockwise to drive the adjusting screw 22 to rotate counterclockwise. At this time, under the action of the thread force, the upper driving part 3 moves upward under the drive of its threaded sleeve 32, and the lower driving part 4 moves downward under the drive of its threaded sleeve 32. The distance between the clamping arms 71 in the first clamping part 7 and the second clamping part 8 increases. When the distance between the clamping arms 71 in the first clamping part 7 and the second clamping part 8 meets the usage requirements, the operator can place the negative pressure insulation board to be positioned between the clamping arms 71 of the first clamping part 7 and the second clamping part 8. Subsequently, the Fuyang insulation board can be positioned. For clamping and positioning, specifically, the handwheel 21 can be rotated clockwise to drive the adjusting screw 22 to rotate clockwise. At this time, under the action of the threaded force, the upper driving part 3 moves downward under the drive of its threaded sleeve 32, and the lower driving part 4 moves upward under the drive of its threaded sleeve 32. Simultaneously, the first clamping part 7 and the second clamping part 8 move relative to each other under the drive of the upper driving part 3 and the lower driving part 4. The clamping arms 71 in the first clamping part 7 and the second clamping part 8 also move relative to each other to clamp the negative pressure insulation board. When the clamping arm 71 contacts the negative pressure insulation board, the buffer spring 74 fitted on the guide screw 72 can cushion the clamping arm 71, thereby preventing the clamping arm 71 from making hard contact with the edge of the negative pressure insulation board and causing damage. The above shows and describes the basic principle, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
