The second long slat 431 is provided with the long auxiliary opening 4313, so that the first long slat 421 can pass through, and the structure can ensure that the limit connection part on the sliding connection block 44 is subjected to balanced stress, so that the sliding connection block 44 can stably move in the adjusting process, and the sliding connection block 44 is prevented from inclining. Simultaneously, the structure can also ensure the support of the first lath 421 and ensure the adjustment stability of the first lath 421
It should be noted that the thickness of the second long slat 431 in the vertical direction needs to be larger than the thickness of the first long slat 421 in the vertical direction.
In some embodiments, the second slat 431 may have a structure as shown in fig. 5. Referring to fig. 5, both ends of each second slat 431 are provided with a second elongated connection port 4312 through which a second adjusting bolt 432 passes, and the second elongated connection ports 4312 are provided along the length direction of the second slat 431.
The arrangement of the second strip connection port 4312 ensures the adjustment of the angle of the second strip plate 431, namely, the length direction of the second strip plate 431 can form a certain included angle with the interval direction of the two long frames 411, and the structure can adapt to irregularly arranged electric contact ends on a frequency element, namely, the interval between two adjacent electric contact ends is smaller, and the interval between the other two adjacent electric contact ends is larger, namely, four electric contact ends are enclosed to form a trapezoid structure. When the second long slat 431 is tilted, the second adjusting bolt 432 can slide relatively in the second long connecting port 4312, so as to ensure the angle adjustment of the second long slat 431, see fig. 7, but it should be noted that when the special frequency element is encountered, the number of the measured frequency elements is halved, that is, four slots 51 are assumed, and when the irregular frequency elements are measured, two slots cannot be used, and only two frequency elements can be measured.
