Background

Referring to fig. 1, 2 and 3, a conventional horizontal measuring tool includes two parallel Y-axis iron plates 11 and an X-axis iron plate 12 vertically disposed on the Y-axis iron plates 11, and is adapted to be disposed on a group of detecting devices 18, so that the detecting devices 18 can measure an object 19 (e.g., a PCB).

When the detecting device 18 detects the position and needs to move the position, the detecting device 18 needs to be moved left and right on the X-axis iron plate 12 as shown in fig. 2, or the X-axis iron plate 12 needs to be moved back and forth as shown in fig. 3. However, when the detecting device 18 is moved left and right, the relative position or angle between the detecting device and the object 19 is not only changed along the axis, so that it is necessary to spend time again to correct the relative position. When the X-axis iron plate 12 is moved back and forth, the X-axis iron plate 12 may not be perpendicular to the Y-axis iron plate 11 due to uneven force applied to the two sides, and thus the relative position or angle between the detecting device 18 and the object 19 to be detected may be changed, and it is necessary to spend time to correct the relative position. Also, since the X-axis iron plate 12 is simply placed on the Y-axis iron plate 11, if the X-axis iron plate 12 is inadvertently moved too much, the X-axis iron plate 12 and the detecting device 18 may fall down to impact and damage the object 19.

In this way, the position of the bridge module 21 can be stabilized and is not easily moved. It should be noted that the fixing groove 221 can be a through groove for the foot seat 211 to penetrate, or a groove for the foot seat 211 to be placed.
