The accommodating groove 210 is used for accommodating the battery 700, and the accommodating groove 210 can limit the battery 700, so as to limit the battery 700 to move forwards, backwards, leftwards, rightwards and other horizontal directions. The probe mounting assembly 400 is located above the carrier 200.

In order to conveniently carry the probe test device, the probe test device is further provided with two handles 600, one handle 600 is fixed at the left end of the bottom plate 110, and the other handle 600 is fixed at the right end of the bottom plate 110. By holding the two handles 600, the probe test device can be conveniently carried.

Specifically, the driving assembly 300 includes a cylinder 310, a guide shaft 320, a guide sleeve 330, and a limit assembly 340. The cylinder body of the cylinder 310 is fixed to the bottom plate 110, and the piston rod of the cylinder 310 is fixedly connected to a lifting plate 411 of the adjusting bracket 410. Four guide shafts 320 are arranged, the length directions of the four guide shafts 320 are all arranged along the up-down direction, and the four guide shafts 320 are arranged at intervals. Each guide shaft 320 is sleeved with a guide sleeve 330, two guide sleeves 330 are fixed on one lifting plate 411, and the other two guide sleeves 330 are fixed on the other lifting plate 411. The guide shaft 320 and the guide sleeve 330 mainly serve to define the sliding direction of the adjustment frame 410.

Therefore, after the air cylinder 310 is ventilated, the adjusting frame 410 can be driven to move up and down, and the first probe 430 and the second probe 440 can be driven to approach or separate from the battery 700, so that the detection of the first probe 430 and the second probe 440 can be completed.

The buffer 344 is sleeved on the screw 345, and the buffer 344 is fixed to the adjusting nut 343.

Therefore, when the cylinder 310 drives the adjusting bracket 410 to move downwards, the lifting plate 411 contacts the cushion 344, so that the limit position of the downward movement of the lifting plate 411 is defined, the first probe 430 and the second probe 440 are protected, and the probability that the first probe 430 and the second probe 440 excessively press the battery 700 is reduced. When the limit position of the downward movement of the lifting plate 411 needs to be adjusted, the cushion 344 moves to a set position by rotating the adjusting nut 343, and then the locknut 342 is rotated to enable the locknut 342 to abut against the adjusting nut 343, so that the adjusting nut 343 is prevented from loosening, and the position adjustment of the cushion 344 can be completed.

It should be noted that the air cylinder 310 may be replaced by an oil cylinder, a linear motor, or the like, so as to move the adjusting bracket 410 up and down.

By making the air flow through the first probe 430 and the second probe 440, heat generated when the first probe 430 and the second probe 440 pass through the current can be taken away, and thus the working process of the first probe 430 and the second probe 440 for detecting the capacity of the battery 700 can be accurately simulated, so that the detection results of the first probe 430 and the second probe 440 can more accurately reflect the actual use condition.

Accordingly, by blowing air to the first and

second probes

430 and 440 in three directions, heat exchange between the first and

second probes

430 and 440 and air can be accelerated, thereby facilitating a reduction in temperature of the first and

second probes

430 and 440. Such a heat dissipation assembly 500 is advantageous in extending the lifespan of the first and

second probes

430 and 440 when the first and

second probes

430 and 440 actually detect the capacity of the battery 700. By using such a heat dissipation assembly 500, the quality of the first probe 430 and the second probe 440 under such heat dissipation conditions can be detected.

Referring to fig. 10, in a modification of the above embodiment, the material of the adjustment bracket 410 and the mounting member 420 is aluminum.
