[0036] Two symmetrically arranged buffers 10 are fixedly connected to the top rear end of the base plate 7. The buffers 10 can buffer and limit the rear of the carrier plate 302 to reduce the impact force.

[0037] Working principle: During testing, the continuous module 4 is inserted into the carrier plate 302. Then, the double switch on the base box 1 is turned on. When the rodless cylinder 11 is turned on, the slide block 12 on the output block of the rodless cylinder 11 moves backward. During the movement, the carrier plate 302 and the pad plate 301 are driven along the slide rail 8 into the lower part of the top cover 2 through the floating block 13. The buffer 10 is used to buffer the impact force of the movement. Then, the side cylinder 502 is turned on, so that the fixed plate 503 moves down. During the downward movement, the bottom of the pressure bar 507 presses the continuous module 4 below. The guide post 504 is inserted into the base plate 7 and the upper guide post 506 is inserted into the carrier plate 302 to form a positioning. The probe 509 tests the continuous module 4 and transmits the test structure to the external industrial control computer and display. After the test is completed, the detection component 5 is retracted and the placement component 3 is removed, and the continuous module 4 is taken out.
