Embodiment 1

[0038] like Figure 1-2 As shown, the plurality of heating sheets 1 are arranged in parallel and equally spaced between the left end support plate 6 and the right end support plate 7 . like Figure 9 As shown, the heating sheet 1 used in Embodiment 1 is a single hollow structure, and the left or right surface of the heating sheet 1 is provided with an opening 23, and the power connection port 19 is provided on the shell on both sides of the opening 23. Body 16.

[0039] like Figure 1-2 As shown, the telescopic device 2 is a number of No. 1 telescopic chains 8, and a No. 1 telescopic chain 8 is fixedly connected between every two adjacent heating sheets 1 among the plurality of heating sheets 1 arranged in parallel and equally spaced. The leftmost heating sheet 1 among the several heating sheets 1 arranged in parallel and equally spaced is fixedly connected with a No. 1 telescopic chain 8 between the left end support plate 6, the most of the several heating sheets 1 arrange...

Embodiment 2

[0043] like image 3 , 5 , 18, several heating sheets 1 are arranged end-to-end in a V shape between the left end support plate 6 and the right end support plate 7, wherein the narrow side of the upper surface of the left heating sheet 1 and the lower surface of the right heating sheet 1 Narrow side is connected by connecting hinge 11, and electric heater just is long up and down, short form front and back. The connecting hinge 11 includes a No. 1 folding board 12, a No. 2 folding board 13, and a connecting shaft 14. Among the several heating sheets 1 arranged end-to-end in a V shape, the adjacent two heating sheets 1 are connected at the joint. Several No. 1 folding boards 12 and several No. 2 folding boards 13 are respectively fixedly connected, and the corresponding No. 1 folding boards 12 and No. 2 folding boards 13 are rotatably connected by connecting shafts 14 .

[0044] like image 3 , 5 As shown, the telescopic device 2 includes a number of No. 2 telescopic chains...

Embodiment 3

[0050] like image 3 , 4 As shown, the difference between the third embodiment and the second embodiment is the telescopic device 2 . like Figure 4 , 5 , 19, the telescopic device 2 in the third embodiment is a plurality of springs 15 arranged on the connecting hinge 11, the springs 15 pass through the connecting shaft 14 and are arranged on the first folding plate 12 and the second folding leaf Between the plates 13, the two ends of the spring 15 are fixedly connected to the No. 1 folding plate 12 and the No. 2 folding plate 13 respectively. When the spring 15 is in a normal state, a certain angle can be maintained between the No. 1 folding plate 12 and the No. 2 folding plate 13, so that several electric heating plates 1 between the left end support plate 6 and the right end support plate 7 are V-shaped. Arranged end to end, the left end support plate 6 and the right end support plate 7 are squeezed to the middle, and the spring 15 is in a compressed state, thereby real...
