As deformation, first probe assembly 3 and the second probe assembly 5 in the vertical direction can also be only driven to rise Fall motion, or only the first probe assembly 3 of drive part and the second probe assembly 5 move up and down, but must be relatively to set The first probe assembly 3 put and the second probe assembly 5.

As the preferred embodiment of the first lowering or hoisting gear 6, as shown in Fig. 2 the first lowering or hoisting gear 6 includes

First track plates 61, are vertically arranged on first fixed structure 2 or the end wall of the second fixed structure 4；

First slide block 62, is slidably arranged on the first track plates 61；

Rebound 63, is vertically arranged, and side wall is fixed on the first slide block 62, and opposite side wall is fixed the first probe assembly 3 or second probe assembly 5；

First driver 64, is fixed on the first connecting plate 7, and its drive shaft is connected to rebound through the first connecting plate 7 63.

First lowering or hoisting gear 6 of this structure, positioned at the top of the first probe assembly 3 or the second probe assembly 5, the 3rd driving Device 93 directly drives rebound 63 and drives and is fixed on the first slide block 62 on the first probe assembly 3 or the second probe assembly 5 the Slide on one track plates 61, and then realize the motion in vertical direction of the first probe assembly 3 or the second probe assembly 5.

It is further preferred that the first driver 64 is cylinder, or others driver of the prior art.

As the deformation of the first lowering or hoisting gear 6, the first lowering or hoisting gear 6 can also be lifting dresses other in prior art Put, only need to meet driving the first probe assembly 3 or the second probe assembly 5 moves up and down in vertical direction.

As the preferred embodiment of the second fixed structure 4, as shown in figure 4, the second fixed structure 4 includes level board 41 He Two cant boards 42, two cant boards 42 are separately fixed on the both ends of level board 41, and perpendicular to level board 41 to downward Stretch, the first connecting plate 7 is fixed on level board 41, the second probe assembly 5 is arranged on the wall outer surface of cant board 42.? That is, this level board 41 and two cant boards 42 form "Ji" type.

Second fixed structure 4 of this structure, when driving means 8 drive level board 41 to move on chassis 1, drive is arranged on The second probe assembly 5 on two cant board 42 wall outer surface is overall to be moved towards or away from the first probe assembly 3 direction, from And in the One On The Chassis confined space, drive multiple second probe assemblies 5 to move on chassis so that probe apparatus are same simultaneously When location points multiple on wiring board are carried out with impedance detection, improve the detection efficiency of probe apparatus, and make whole probe apparatus Compact conformation, shared space is less.

As deformation, the second above-mentioned fixed structure 4 can also be the shape of falling u, or other shapes, only need to realize second The function of the second probe assembly 5 is fixed on the both ends of fixed structure 4.

It is further preferred that as shown in figure 3, driving means 8 include installing plate 81, screw mandrel 821 assembly and the second driver 85；Installing plate 81 is be arranged in parallel with level board 41, and bottom is fixed on chassis 1；Screw mandrel 821 assembly is located at the second fixed structure 4 Relative with first fixed structure 2 layer, including screw mandrel 821 with the nut block 822 that is set on screw mandrel 821, nut block 822 It is fixed on the lower section of level board 41, screw mandrel 821 sequentially passes through installing plate 81, the lower section of level board 41, and end and stretches into and be opened in In through hole on first fixed structure 2；Second driver 85 is fixed on installing plate 81, rotates for drive screw 821.

When second driver drives screw mandrel 821 rotates, nut block 822 is driven to move along a straight line along screw mandrel 821 axis direction, And then drive level board 41 to move towards or away from the first probe assembly 3 direction, realize the second probe assembly 5 and the first probe group Spacing adjustment between part 3.

It is further preferred that the second driver 85 is motor, or other driving means of the prior art, only need to realize The function that drive screw 821 rotates.

It is further preferred that driving means 8 also include rotating limiter assembly, for limiting nut block 822 in screw mandrel 821 Rotate in a circumferential direction under drive.Because screw mandrel 821 rotation can drive nut block 822 to have rotation in circumference, so that nut block 822 is not Can merely move along a straight line, the accuracy of spacing adjustment between the second probe assembly 5 and the first probe assembly 3 can be affected, Rotary spacing assembly is then set, to limit the circumferential movement that screw mandrel 821 drives nut block 822, so that nut block 822 is only Axis direction along screw mandrel 821 moves along a straight line, and improves spacing adjustment between the second probe assembly 5 and the first probe assembly 3 The degree of accuracy, improve probe apparatus accuracy of detection.

It is further preferred that rotary stopper assembly includes two the second track plates 83 and two the second slide blocks 84, two Two track plates 83 are vertically arranged and parallel to screw mandrel 821, and the bottom of two track plates is fixed on chassis 1, and are located at screw mandrel 821 Both sides；Two the second slide blocks 84 are slidably arranged on second track plates 83 respectively, the two ends bottom of the lower section of level board 41 Second slide block 84 is fixed in portion respectively.

In this embodiment, when screw mandrel 821 rotates, because two cant boards 42 are located at the outer surface of the second track plates 83 Locate, the second track plates 83 will limit the rotation of two cant boards 42, and then limit nut block 822 to rotate with screw mandrel 821, make Obtain nut block 822 only to move along a straight line on the axis direction of screw mandrel 821；Meanwhile, the setting of the second track plates 83, by screw mandrel 821 bearing capacities bearing the second fixed structure 4 are transferred on the second track plates 83, reduce the active force that screw mandrel 821 bears in itself, Thus playing a protective role to screw mandrel 821；In addition also allow for level board 41 to slide on the second track plates 83 it is easier to realize Two probe assemblies 5 are towards or away from the movement in the first probe assembly 3 direction.

As deformation, the quantity of the second slide block 84 can be two, three, four or five etc., specifically arranges number Depending on actually used situation, but at least provided with second slide block 84 on second track plates 83.

As further preferred embodiment, as shown in Figure 2 and Figure 5, chassis 1 opens up two first through holes 11, the The bottom two ends of one fixed structure 2 have the projection 21 extending downwardly, and two projections 21 are located in a first through hole 11 respectively, So that the first probe assembly 3 is located in first through hole 11；Two cant boards 42 of the second fixed structure 4 are located at one first respectively In through hole 11；So that the second probe assembly 5 is located in first through hole 11.
