The working principle of the invention is as follows: when the heat preservation plate is used, the left part and the right part of the heat preservation plate are respectively placed on the upper sides of the two bottom clamping plates 202, and the two top clamping plates 3 can respectively vertically slide on the two vertical guide plates 203, so that the two vertical guide plates 203 are equalized on the upper sides of the heat preservation plate, and the left part and the right part of the heat preservation plate are clamped and fixed; the two sliding strips 2 can slide left and right, so that the two bottom clamping plates 202 and the two top clamping plates 3 are driven to slide left and right, the distance between the two bottom clamping plates 202 is adjusted, and the fixing of heat-insulation plates with different sizes is adapted; hollow column 401 can be on intermediate lamella 4 vertical slip, and then drives arc 402 and reciprocate for arc 402 is located the downside of heated board, pushes up arc 402 at the downside of heated board, and then bends the heated board, makes the heated board adapt to the building of arc wall. Air inlet joint 406 can pour into the hot-air into on the hollow hole on hollow column 401, and then pours into hot-air into arc groove 403 department into, and when arc 402 pushed up the downside at the heated board, the hot-air of arc groove 403 department was absorbed by foam's heated board for the heated board is buckled by the pressure more easily, and treats to do benefit to the shaping of heated board after the heated board cools off more. The double-shaft motor 404 can drive the two screws 405 to rotate, and then drive the two sliding bars 2 to be close to or away from each other, control the distance between the two sliding bars 2, and then adjust the distance between the two bottom clamping plates 202, and adapt to the fixation of the heat-insulating plates of different sizes. Two compression spring I give two top splint 3 decurrent power respectively for two top splint 3 can press the upside of heated board and fix the both sides of heated board. And after the heated board is bent by the pressure, top splint 3 can reciprocate a section of small distance, and the heated board of being convenient for is crooked, prevents that the both sides of heated board from splitting. Two top splint 3 press behind the upside of heated board, move a plurality of contact pins 306 on the strip 305 from side to side and insert the upside at the heated board to move the strip 305 from side to side and can slide from side to side on two round bar 302, can press one of them spring leaf 304 when moving the strip 305 from side to side, spring leaf 304 carries out the return to the position of moving the strip 305 from side to side. After the heated board is buckled, the heated board can be by controlling tensile, moves a plurality of contact pins 306 on the strip 305 about two and insert respectively on the both sides of heated board, prevents that the both sides of heated board from droing to after the heated board can control tensile, control and move the one end distance that the strip 305 can inwards slide, stretch to the left and right sides of heated board and adapt to, make both sides by firm fixed about the heated board. Electric putter II105 extends or can drive square column 501 and slide from top to bottom when shortening, and then drive well piece 5 and slide from top to bottom, can press on the heated board when well piece 5 moves down, and the heated board laminating of being convenient for is at the upside of arc 402, and the heated board of being convenient for is pressed into the arc. When middle part 5 moved down, two gyro wheels 502 can roll to both sides by the centre at the upside of heated board, rolled into the arc with the heated board for the heated board becomes more regular arc, because the transmission of meshing in the middle of two gears 504 makes can rotate in step between two major axes 505, and then makes two gyro wheels 502 keep the symmetric position throughout and roll the upside of heated board and flatten. The compression springs II on the two transverse rods 601 respectively provide inward force for the two cylindrical sliding blocks 603, so that the two inclined arm rods 503 positioned at the front ends always keep the trend of being close to each other, when the middle block 5 is lifted, the two rollers 502 can be close to each other, and when the middle block 5 moves downwards again, the two rollers 502 roll towards two sides from the middle on the upper side of the heat insulation plate again, and the heat insulation plate is rolled into an arc shape. The two hand screws 205 can be screwed manually to enable the two hand screws 205 to be pressed on the upper side of the top clamping plate 3, and when needed, the two top clamping plates 3 are only pressed on the heat insulation plate to fix the heat insulation plate thoroughly and stably.
