[0002] In foundation pit and slope support, anchor rod is used to transmit tension to stable or suitable rock-soil body. In recent years, anchor rod technology develops rapidly and is widely used in slope support, dangerous rock anchoring, landslide remediation, cavern reinforcement and high-rise building foundation anchoring. After the installation of anchor rod, the construction quality of anchor rod needs to be inspected by pull-out test. In the existing pull-out test, concrete counterforce pier or steel plate is used as counterforce support on both sides of anchor rod. However, the stability of concrete counterforce pier is poor, and the production process is time-consuming and laborious. After the test is completed, the concrete counterforce pier needs to be removed. The steel plate is not easy to hoist and is limited to the stress damage of cement mortar at anchor hole. When the slope is steep, the angle difference between the slope and the jack occurs. For some bridges and tunnels, a large number of anchor rods are inclined. If the existing technology is used to pull up the inclined anchor rod vertically relative to the horizontal base, the anchor rod will be bent and deformed or even broken. Therefore, a special detection device for pull-out test of inclined anchor rod is needed. SUMMARY

[0009] As a third preferred scheme of the utility model, the telescopic rod comprises a screw rod fixedly connected with the spherical rotating supporting leg; and a screw sleeve is arranged on the lower surface of the top plate and matched with the screw rod.
