[0021] The following are specific embodiments of the present invention in combination with the drawings. The technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.
[0022] Embodiment
[0023] As Figures 1-3 shown, a tester vehicle body includes a U-shaped base 7 and two columns 3 connected thereto. The two columns 3 are fixedly arranged on both sides of the U-shaped base 7. Rotation mechanisms 10 are provided at the upper ends of the two columns 3. The two rotation mechanisms 10 are arranged in a mirror image. The rotation mechanism 10 includes a lock handle 13 and a test head connection block 6. A fixed block 5 is provided on one side of the test head connection block 6.
[0024] Embodiment 1: The test head connection block 6 is fixedly connected to the fixed block 5. On one side of the fixed block 5, there are a first bushing 8 and a second bushing 9. There is grease between the first bushing 8 and the second bushing 9 to ensure the lubrication effect of the rotation operation. At the lower end of the locking handle 13, there is a locking screw 4, which is matingly connected to the second bushing 9 and the first bushing 8. The locking screw 4, the second bushing 9, and the first bushing 8 are located on the same axis. The locking screw 4 is an M10*55 screw. The locking screw 4 passes through the column 3 and then is connected to the second bushing 9. The test head connection block 6 is supported by the fixed block 5. The test head connection block 6 is used to connect the test equipment. The fixed block 5 is connected to the column 3 through the second bushing 9, the first bushing 8, and the locking screw 4 to achieve rotation. The fixed block 5 drives the test head connection block 6 to rotate 180 degrees with the bushing as the fulcrum.
[0025] Embodiment 2: The upper end of the column 3 is arc-shaped. The upper end of the column 3 is also provided with an arc-shaped groove 31 and a positioning hole 32. The positioning hole 32 is arranged to match the locking screw 4. The locking handle 13 passes through the arc-shaped groove 31 and is fixedly connected to the fixed block 5. The locking handle 13 is slidably connected to the arc-shaped groove 31. One end of the locking handle 13 is fixed to the upper part of the fixed block 5. By rotating the locking handle 13 and sliding along the arc-shaped groove 31, the rotation operation of the test head connection block 6 is realized. The arc-shaped groove 31 is a semi-circular arc groove, which can realize a 180-degree rotation in the horizontal direction.
