The mesh is pressed by the pressing cylinder 46 so that the mesh itself generates tension, which is then detected by the pressure detection sensor 3.
[0023] Preferably, the hinge point of the enclosure 22 on the hook body 21 and the tension spring 24 are at the same end.
[0024] Preferably, a pair of blocks 211 are provided inside the hook body 21, and the pair of blocks 211 are symmetrically arranged, so that the pair of blocks 211 can make the mesh cloth more secure when hung.
[0025] like Figure 3 The power mechanism 4 also includes a driving motor 41, a sector gear 42 and a spur rack 43. The driving motor 41 is installed behind the sector gear 42.

[0030] Working principle: hang the four corner hooks of the mesh on the corresponding fixed hooks 2, start the driving motor 41, and make the fan gear 42 rotate. The rotation of the fan gear 42 will drive the spur rack 43 to move downward. When the spur rack 43 moves downward, it will press the mesh downward. The mesh begins to generate tension due to the compression. At this time, the pressure detection sensor 3 starts to measure. By moving the spur rack 43 down to different heights, the tension value under different conditions can be detected. A pair of pressure detection sensors 3 work at the same time. After obtaining the values, the average is taken, which can make the detection more accurate.
