[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-3 The measuring probe station of a rotatable probe card in this embodiment includes a support base 1. A receiving groove 2 is formed inside the support base 1. A fixing block 3 is fixedly connected to the bottom wall of the receiving groove 2. An adjusting shaft 4 is movably connected to the inner wall of the fixing block 3. A handle 5 is fixedly connected to one end of the adjusting shaft 4, and a driving worm gear 6 is fixedly connected to the other end of the adjusting shaft 4. A support shaft 7 is movably connected to the bottom wall of the receiving groove 2. A movable worm wheel 8 and a movable platform 9 are fixedly connected to the outer wall of the support shaft 7. A mounting hole 10 is formed in the inner wall of the movable platform 9. A fixing rod 11 is fixedly connected to the top of the support base 1, and a return spring 1 is sleeved on the outer wall of the fixing rod 11. 2 and movable block 13, one end of movable block 13 is provided with probe body 14. Through the provided support seat 1, receiving groove 2, fixed block 3, adjusting shaft 4, handle 5, driving worm gear 6, support shaft 7, movable worm wheel 8, movable table 9, mounting hole 10, fixed rod 11, return spring 12, movable block 13 and probe body 14, it is convenient to drive the movable table 9 to rotate, which is conducive to the movable table 9 to drive the installed object to be measured to adjust the angle, which facilitates the detection of the object at different angles, improves the diversity of testing, and effectively improves the stability of angle adjustment through the self-locking property of the thread.

[0019] Furthermore, the adjusting shaft 4 is rotatably connected to the fixed block 3 via a bearing, and one end of the adjusting shaft 4 with a handle 5 extends out of the receiving groove 2, making it convenient to rotate the adjusting shaft 4.

[0020] Furthermore, the active worm gear 6 meshes with the movable worm wheel 8, and the movable table 9 forms a linkage structure with the movable worm wheel 8 through the support shaft 7, which is beneficial for self-locking operation through the characteristics of the threaded connection.

[0021] Furthermore, the fixing rods 11 are distributed in a "T" shape, and the top diameter of the fixing rods 11 is larger than the diameter of the return spring 12, which facilitates the support of the return spring 12.

[0022] Furthermore, the bottom of the return spring 12 abuts against the top of the movable block 13, and the size of the movable block 13 is larger than the diameter of the return spring 12, which facilitates the return spring 12 to drive the movable block 13 to perform elastic movement.

[0023] Furthermore, the movable block 13 is slidably connected to the fixed rod 11, and the outer wall of the fixed rod 11 has a smooth surface, which facilitates the support of the movable block 13.

[0024] The working principle of the above embodiments is as follows:

[0025] In use, first rotate the handle 5, which drives the active worm gear 6 to rotate via the adjusting shaft 4. The active worm gear 6 drives the movable worm wheel 8 to rotate, which in turn drives the movable stage 9 to rotate via the support shaft 7. This causes the movable stage 9 to adjust the angle of the object being measured. When the movable stage 9 adjusts the object being measured, it presses the probe body 14, causing the movable block 13 to slide upward. This causes the movable block 13 to compress and deform the return spring 12. The elasticity of the return spring 12 causes the movable block 13 to return to its original position and slide, thus keeping the probe body 14 in contact with the object being measured.
