[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the following further describes how the present invention is implemented in conjunction with the accompanying drawings and specific implementation methods.

[0022] See also Figures 1 to 8The utility model provides an auxiliary device for measuring the distance between the traction pin and the suspension on a semi-trailer, comprising a pin seat 1, a pin shaft 2 and a seat plate 3. A plurality of bolts 4 are installed at one end of the pin seat 1, and the other end is connected to the pin shaft 2 through the seat plate 3. When in use, first remove the bolts 4, then buckle the pin seat 1 with the traction pin on the semi-trailer, and then install the bolts 4, and fix the pin seat 1 with the traction pin through the bolts 4. After ensuring that the pin shaft 2 and the traction plate are perpendicular to each other, the horizontal distance between the traction pin and the suspension can be measured with a tape measure from the tip of the pin shaft 2 to the suspension direction.
