[0041] The lower end of the lifting screw 201 is the base, and the base 2 is supported on the horizontal plane.

[0042] Specifically, the embodiment discloses a polygonal evidence plate, and specifically a common triangular or square evidence plate, which can jointly record evidence in three directions or four directions, and ensure the correlation of the evidence. In order to avoid the bottom of the identification body 1 from contacting a large area and being unable to take evidence at the same time, the embodiment is provided with a lifting base 2 on the bottom plate 103 of the identification body 1, so that the lifting base 2 lifts the height of the identification body 1 and keeps the hollow below so as not to touch the adjacent multiple evidence with small spacing, and meanwhile, the base 202 of the lifting base 2 is supported between the evidence, so that the problem of the multiple evidence being too close to each other and being unable to take evidence at the same time can be solved.

[0049] Since the structure of the embodiment is provided with the lifting base 2, which is arranged on the bottom plate 103 in a threaded connection manner, a space for hand holding operation needs to be reserved, therefore, the identification surface of the embodiment is designed as two parts, one part is the straight plate segment 102 at the lower part, and the other part is the slope plate segment 101 at the upper part, the slope plate segment 101 constitutes the pyramid structure of the embodiment, and the straight plate segment 102 is connected with the bottom plate 103 and reserves the hand holding space required during operation.

[0050] Preferably, the length of the lifting screw 201 of the embodiment is less than the height of the identification body 1; by designing the length of the lifting screw 201 to be less than the height of the identification body 1, the lifting screw 201 can be wholly accommodated in the identification body 1 during storage.

[0051] In order to further improve the stability of the support, the base 202 of the embodiment adopts a suction cup base, and the material of the suction cup base is rubber.

[0052] In the above technical solution, the polygonal evidence plate for crime scene provided by the utility model has the following beneficial effects:
