[0023] Referring to Figures 1-2 A portable auxiliary tool for on-site detection of the geometric size of a civil defense door, comprising an L-shaped plate 4, two groups of fixed plates 2 are fixedly connected to the lower end surface of the L-shaped plate 4, the planes of the two groups of fixed plates 2 are arranged vertically, two groups of hinged plates 5 are hingedly connected to the edge of the upper end surface of the L-shaped plate 4, and the planes of the two groups of hinged plates 5 are arranged vertically; a slot is arranged at the corner position of the L-shaped plate 4, and the slot is matched with a ruler claw; magnetic blocks are arranged in the L-shaped plate 4 and the fixed plates 2, and the hinged plates 5 are made of magnetic material.

[0024] The L-shaped plate serves as the basic structural member of the entire auxiliary tool and plays a supporting and connecting role for other components. Two groups of fixed plates 2 are fixedly connected to the lower end surface of the L-shaped plate, and the planes of the two groups of fixed plates 2 are arranged vertically. At the same time, the edge of the upper end surface of the L-shaped plate is hingedly connected to two groups of hinged plates 5, which can be flipped according to the measurement requirements (flipped to a parallel state with the fixed plates 2 when the door leaf needs to be measured; flipped to a vertical state with the fixed plates 2 when the door leaf needs to be measured, and the hinged plates 5 are in close contact with the door leaf). A slot is arranged at the corner position of the L-shaped plate, which is matched with a ruler claw for fixing the ruler claw of the box ruler. Moreover, magnetic blocks are arranged in the L-shaped plate and the fixed plates 2, and the hinged plates 5 are made of magnetic material, which are conveniently installed on the door frame or the door leaf by utilizing the magnetic adsorption characteristics.
