[0046] Working principle:

[0047] During use, place the wiring terminal to be detected on the positioning groove 130, turn the screws 52 on both sides to drive the clamping plates 54 to move through the bearings 53 until the clamping plates 54 on both sides are in contact with the wiring terminal (among them, since the adjusting block 25 with the limiting plate 45 is always in a fixed state, when in use, it is necessary to adjust one end groove of the wiring terminal to the position corresponding to the adjusting block 25 through the clamping plate 54), and then install the pressing plate 14 on the positioning seat 13 through the screws 15 to complete the pressing and positioning of the wiring terminal;

[0048] According to the groove of the wiring terminal to be detected, first adjust the distance between the plug rods 31, and then adjust the height of the plug rods 31 through the telescopic cylinder A2. After the adjustment is completed, start the telescopic cylinder C63 to push the sliding seat 11, and slide along the slide rail 61 to the fine adjustment table 12 through the slider 62. The plug rods 31 move accordingly until they are inserted into the row of grooves on the wiring terminal.

[0049]

[0049] The adjustment method of the insertion rod 31 is as follows: Start the telescopic cylinder B27 to drive the adjusting block 25 at the end to move through the connecting frame 26 at its movable end, so that the adjusting block 25 slides along the sliding rod 24. Through the equidistant adjustment mechanism, the remaining adjusting blocks 25 are driven to slide the same distance along the sliding rod 24 until the insertion rod 31 and its internal structure are adjusted to a position corresponding to the terminal groove.
