The sliding effect of the limit block 494 enables the limit block 494 to be engaged or released with the slot, and the outer wall of the limit block 494 is engaged with the inner wall of the slot.

[0039] Reference Figure 3 One end of the spring 412 is fixedly connected to the left end of the bottom of the mounting plate 1, and the other end of the spring 412 is fixedly connected to the top of the movable block 48. The fixing effect of the spring 412 prevents the spring 412 from falling off. The inner wall of the movable block 48 is slidably connected to the outer periphery of the fixed column 411. The sliding effect of the movable block 48 drives the hinge block 46 to slide.

[0040] Working principle: When the staff needs to use the detection instrument to detect the metrological parameters of the calibration station, the staff holds the handrail 2 and pushes the mounting plate 1 to move, so as to move the detection instrument integrated on the mounting plate 1 to the designated detection position for detection. When the staff moves to the designated position, the staff presses the pedal to drive the telescopic rod 410 to rotate downward, so that the movable block 48 slides upward along the outer wall of the fixed column 411, so that the hinged rod 47 drives the hinged block 46 to slide to the right, so that the cylindrical rod 45 slides to the right along the inner wall of the slide groove, and at the same time drives the two groups of connecting rods 42 to move, and the two groups of support plates 41 are driven downward by the two groups of connecting rods 42 respectively, so that the bottom of the two groups of support plates 41 contacts the ground, thereby increasing the contact area and friction between the mounting plate 1 and the ground, and improving the stability of the mounting plate 1 and multiple groups of detection instruments. At the same time, the limit block 494 is clamped with the card slot under the elastic force of the limit spring 493, and the guide rod 43 is limited at the same time, so that the support plate 41 remains fixed.

[0041] Then the staff presses the wedge block 54 to release the clamping effect on the dust cover 51, and removes the dust cover 51, which is convenient for the staff to use the detection instrument to perform flow detection. When the detection is completed, the staff pulls the pull rod 491 to the right, and the pull rod 491 simultaneously drives the two groups of sliding bars 492 to slide to the right, so that the two groups of limit blocks 494 are simultaneously released from the clamping effect on the two groups of slots, thereby releasing the limiting effect on the two groups of guide rods 43. At this time, the elastic force of the spring 412 drives the movable block 48 to slide downward, so that the two groups of support plates 41 move upward for reset, which is convenient for the staff to continue to move the mounting plate 1 to the next position that needs to be detected.

[0042] When all the inspection work is completed, the staff will connect the through groove on the dust cover 51 with the mounting column 52, so that the wedge block 54 is clamped with the top of the dust cover 51 under the elastic force of the compression spring 53, so that the dust cover 51 remains fixedly installed on the mounting plate 1, thereby preventing dust from entering the instrument on the mounting plate 1.
