Further, the bottom of the back plate is provided with an extension plate 504, and since the second platform 402 is horizontally arranged, the back plate horizontally extends, and the back plate is connected to the second platform 402 through the extension plate 504. Be provided with second lead screw 505 on the backplate, second lead screw 505 is vertical to be set up, and second lead screw 505 can rotate on the backplate, is provided with second connection structure on the second lead screw 505, and second lead screw 505 pivoted in-process, second connection structure can remove on second lead screw 505, and second connection structure is connected with first platform 401, and first platform 401 can adjust for the height of backplate promptly. Specifically, to further define the first platform 401 to perform linear motion, a second sliding rail 506 is disposed on the back plate, a second groove is disposed on the first platform 401, the second groove is connected with the second sliding rail 506, two second sliding rails 506 are disposed, and correspondingly, two second grooves are disposed.
In some examples, a third sliding rail 507 is disposed at the top of the second platform 402, a third groove is disposed at the bottom of the extension board 504, and the third groove is connected with the third sliding rail 507, so that the first platform 401, together with the test head 403, and the second platform 402 can perform relative movement, and the position of the test head 403 is further adjusted to adapt to the specific position of the keyboard.
Further, since the testing position is below the second platform 402, to ensure that the testing head 403 can reach the testing position, the second platform 402 is hollow, and the first connection structure 502 can pass through the second platform 402.
As shown in fig. 9, in some examples, the keyer further includes a pressing plate 508, where the pressing plate 508 is located at a testing position, that is, the pressing plate 508 is located below the second platform 402, the pressing plate 508 is located above the second lifting platform 204, and a plurality of through holes are disposed on the pressing plate 508, and the shapes and positions of the through holes respectively correspond to those of the keys on the keyboard. After the test head 403 passes through the via hole, the position of the key of the keyboard can be accurately reached, when the test head 403 is blocked by the pressing plate 508, the position of the test head 403 needs to be further adjusted, the validity of the test work is ensured, and the test efficiency is improved.
