A mounting block 1122 is provided on the base plate 112, the mounting block 1122 being provided near a long edge of the base plate 112, the mounting block 1122 being provided in particular near a long edge adjacent to the testing position (a long edge facing away from the handle 1512, i.e. a long edge on the rear side of the base plate 112), the mounting block 1122 being located on a side of the stopper 156 facing away from the handle 1512, at least one stopper rod 1123 being connectable to the mounting block 1122, the axial direction of the stopper rod 1123 being parallel to the width direction of the base plate 112, the stopper rod 1123 being adapted to abut against the stopper 156 when the push-pull plate 1511 is moved towards the testing position to the extreme position.

In addition, a mounting block 1122 may be provided near the middle region on the bottom plate 112, and a stopper rod 1123 axially parallel to the width direction of the bottom plate 112 may be connected to the mounting block 1122, and the stopper rod 1123 is configured to abut against the stopper 156 when the push-pull plate 1511 moves to the limit position away from the testing position.

Referring to fig. 4 and 5, the horizontal movement assembly 15 may further include: the locking piece 157 is used for locking the horizontal movement assembly 15 and the bottom plate 112 of the base 11 when the push-pull plate 1511 drives the BDU 2 to move to the testing position, so as to ensure testing reliability. In some examples, the locking member 157 may include a locking post, with a sliding aperture provided on the push-pull plate 1511, the sliding aperture may be disposed proximate a side of the push-pull plate 1511 facing away from the handle 1512, the locking post slidably disposed in the sliding aperture, and correspondingly, the base plate 112 may be provided with a locking aperture 112a, with the locking aperture 112a disposed proximate a long edge of the base plate 112 proximate the testing position (i.e., a long edge facing away from the handle 1512, i.e., a long edge of the rear side of the base plate 112), the locking post being capable of being inserted into the locking aperture 112a when the push-pull plate 1511 is in the testing position. When it is desired to pull out the push-pull plate 1511, the locking posts can be disengaged from the locking holes 112 a. The locking posts may include a plurality of locking posts spaced apart.

In other examples, a threaded hole is provided in the push-pull plate 1511, which may be located near a side of the push-pull plate 1511 facing away from the handle 1512. The locking member 157 may be a locking bolt 1571, with an externally threaded section of the locking bolt 1571 being capable of mating with a threaded bore. Thus, by rotating the locking bolt 1571, the locking bolt 1571 may be moved downward and inserted into the locking hole 112a, or the locking bolt 1571 may be moved upward until the locking bolt 1571 is disengaged from the locking hole 112 a.

Then, the locking member 157 is released from locking the horizontal moving assembly 15, the carrier plate 152 is driven by the push-pull plate 1511 to move to a position far away from the testing position, the BDU 2 to be tested is placed on the carrier plate 152, then the carrier plate 152 is driven by the push-pull plate 1511 to move to the testing position, the detection point on the BDU 2 is opposite to the probe 133 in the vertical moving assembly 13, and the horizontal moving assembly 15 is locked with the bottom plate 112 of the base 11 by the locking member 157.

The mounting plate 132 and the probes 133 are then driven downward by the first driving member 131 in the vertical movement assembly 13 until the probes 133 are electrically connected to the probing points on the BDU 2, so that the plurality of probes 133 mounted on the mounting plate 132 can be respectively connected to the probing points on the BDU 2.

When the test is completed, the probe 133 is driven to move upwards by the first driving member 131 in the vertical movement assembly 13, so that the vertical movement assembly 13 is separated from the second guiding hole 152a and the BDU 2, and the supporting plate 152 and the BDU 2 are driven to move to a position far from the test position by the push-pull plate 1511, and the BDU 2 is taken out.
