[0030] The specific setting and function of the support structure 5 and the guide structure 6 will be described below.
[0031] Referring to Figures 1-4 As shown in the embodiment: the support structure 5 includes a support plate 51 fixedly connected to the surface of the base 4, two moving bars 55 are slidably connected inside the support plate 51, a driving bar 56 is fixedly connected to the upper surface of the moving bar 55, the driving bar 56 is of V-shaped structure, two limiting bars 52 are fixedly connected to the surface of the support plate 51, a sliding bar 54 is slidably connected to the outside of the two limiting bars 52, a lead screw 57 is threadedly connected to the inside of the driving bar 56, and the lead screw 57 is rotatably connected to the inside of the support plate 51. By providing the support structure 5, it is convenient to flexibly suspend and support the pressure testing pipe 1, thereby facilitating the subsequent sleeving work of the test steel pipe 2 and improving the detection efficiency of the pressure testing machine for measuring steel pipes. The spring 53 is fixedly connected between the sliding bar 54 and the limiting bar 52. The sliding bar 54 will be moved to the side close to the support plate 51 under the action of the spring 53 on the limiting bar 52, and the two sliding bars 54 can be removed from the outside of the pressure testing pipe 1.
