Since push block 6 blocks the docking hole, one end of fixed rod 9 is in contact with the upper end face of push block 6. Then, test liquid is injected into horizontal box 10 and the height of test liquid is made to be level with horizontal test line. Then, housing 1 is pushed between two clamping blocks 5. During the movement of housing 1, housing 1 will exert pressure on push block 6, and push block 6 will squeeze spring 7 until spring 7 contracts.

[0024] When the connecting hole 3 on the housing 1 coincides with the mating hole on the clamping block 5, the fixing rod 9 falls down, fixing the housing 1 between the two clamping blocks 5. Then, observe the position of the test liquid in the horizontal box 10 and adjust the horizontal angle of the housing 1 by using the two adjusting rods 11.
