[0030] The sleeve rod 307 is fixedly connected to the interior of the slide groove 104 , and the positioning plate 308 is fixedly connected to the interior of the slide groove 104 .

[0031] What needs to be further explained is that: a test probe 102 and a probe box 203 are respectively provided on the test tool body 1 and the gantry 2. When the handle 206 drives the top plate 202 to be pressed down, the pressing rod 204 at the bottom of the top plate 202 contacts the top of the positioning head 401 and squeezes the positioning head 401 and the carrier 301.

[0037] What needs to be further explained is that the circuit board body 105 is placed on the top of the positioning head 401. When the downward pressure rod 204 at the bottom of the top plate 202 moves away from the positioning head 401, the spring 2 403 at the bottom of the positioning head 401 is released from compression. The tension of the spring 2 403 causes the slide rod 402 and the positioning head 401 to rise from the inside of the positioning block 404, and at the same time drives the circuit board body 105 to rise. The gap between the circuit board body 105 and the carrier 301 is large, which facilitates the removal of the circuit board body 105.

At this time, the circular groove 305 at the bottom of the carrier 301 slides down and squeezes the spring 1 306 until the bottom of the carrier 301 contacts the gasket 103. At this time, the probe box 203 contacts the top of the circuit board body 105 and drives the circuit board body 105 to descend so that its bottom contacts the test probe 102, so as to facilitate the testing of the circuit board body 105. A carrying mechanism 3 is provided on the top of the test tool body 1. The carrying mechanism 3 is provided to facilitate the carrying of the circuit board body 105 for testing. A positioning mechanism 4 is provided on the top of the test tool body 1. The positioning mechanism 4 is provided to facilitate the removal of the circuit board body 105 after the test is completed.

[0039] When it is necessary to take the circuit board body 105 after the test is completed, the circuit board body 105 is first placed on the top of the positioning head 401. When the downward pressure rod 204 at the bottom of the top plate 202 moves away from the positioning head 401, the spring 2 403 at the bottom of the positioning head 401 is released from compression. The tension of the spring 2 403 causes the slide bar 402 and the positioning head 401 to rise from the inside of the positioning block 404, and at the same time drives the circuit board body 105 to rise. The gap between the circuit board body 105 and the carrier 301 is large, which is convenient for taking the circuit board body 105. The device is convenient for taking the circuit board body 105 after the test is completed.
