The design of the slide groove 201 on the second vertical rod 200 enables the cross bar 102 to slide accurately along its length direction, and the 1 mm distance between each side wall of the slide groove 201 and the side wall of the cross bar 102 provides the necessary clearance, ensuring the smoothness of sliding and preventing the problem of poor sliding or shaking caused by being too tight or too loose. This design helps to improve the accuracy and stability of measurement.
[0096] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.
[0097] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
