The surface of the fixed plate 201 and the inner wall of the transparent movable cover 401 are respectively and fixedly provided with a guide plate 313, the middle part of the guide plate 313 is provided with a guide groove 314, the inner wall of the guide groove 314 is movably connected with two movable rods 315, the two movable rods 315 are respectively and fixedly arranged at the top and the bottom of a guide rail 307, the front side end of the fixed plate 201 is fixedly provided with a second double-head telescopic rod 316, the second double-head telescopic rod 316 is fixedly arranged at the inner wall of the transparent movable cover 401, through the arrangement of the guide plate 313, the guide groove 314 and the movable rods 315, when the fixed shell 1 and the transparent movable cover 401 move relatively, the angles of the transparent movable cover 401 and the fixed box 407 inside the fixed shell 1 are changed, so that the width change of the device is adapted, and when the device is used for simultaneously measuring the horizontal and vertical inclination angles of a wall, at the moment, the guide plate 313 on the inner wall of the transparent movable cover 401 is matched with the guide plate 313 on the The front side end is vertically disposed, thereby preventing the guide rail 307 from being inclined when the vertical inclination angle measurement is performed, to affect the measurement result.

The working principle is as follows: when the device is used, the fixed shell 1 is firstly clung to a wall body with an angle to be measured when the device is used, when the wall body is inclined, the vertical pipe 202 and the mercury liquid 207 in the arc-shaped pipe 203 are inclined, the positions of the mercury liquid 207 on the arc-shaped pipe 203 and the vertical pipe 202 corresponding to the first contacts 205 are changed, at the moment, the mercury liquid 207 serves as a conductive medium in the arc-shaped pipe 203 and the vertical pipe 202 by turning on the control switch, a passage is formed between the two corresponding first contacts 205, the first LED lamps 206 in the passages of the two corresponding first contacts 205 are turned on, and when the scale marks corresponding to the first LED lamps 206 on the surface of the fixed plate 201 are watched by human eyes, the angle observed by the human eyes cannot be limited, so that the identification of the inclination angle is accurate, and the first contacts 205 at one end of the arc-shaped pipe 203 are matched with the first LED lamps 206, First contact 205 and first LED lamp 206 of the arc pipe 203 other end cooperate and first contact 205 and first LED lamp 206 on standpipe 202 surface cooperate for can get its average numerical value with the scale mark of three show, and then can further improve the accurate nature of differentiateing wall body inclination, thereby can realize the accurate mesh of differentiateing wall body inclination.
