[0034] In the embodiment, the working principle of the utility model is as follows:

[0035] As Figures 1 to 10 shown, the non-working state, due to the role of the second spring 224 and the role of the second contour screw 225 as a guide and limit, the second layer of floating block 223 will be in the floating state.

The front connecting rod 5 and the rear connecting rod 6 are fixed on the right end of the second cross arm 202 and the left end of the first cross arm 201 respectively, and the horizontal and vertical distance from the front connecting rod 5 and the rear connecting rod 6 to the connecting shaft 203 is equal, so the front connecting rod 5 and the rear connecting rod 6 can realize equal distance downward. The first floating pressure rod 206 and the second floating pressure rod 207 will exert force on the second layer of floating block 223 and move downward together during the downward process. Because the elastic force of the second spring 224 is greater than that of the first spring 221, the first layer of spring 221 will be compressed first, and the first layer of floating block 220 and the second layer of floating block 223 as a whole form the double-layer floating structure 22 to move downward.

[0037] The needle block module 4 is fixed on the floating plate element 3, and the floating plate element 3 is fixed on the first layer of floating block 220 on both sides. Therefore, the needle block module 4 and the floating plate element 3 will move downward together with the first layer of floating block 220. When the floating plate element 3 presses the two sides of the product jig 7 to be matched, the first layer of floating block 220 stops moving. At this time, the first floating pressure rod 206 and the second floating pressure rod 207 continue to press down, the second spring 224 starts to compress, and the second layer of floating block 223 continues to move downward until the buckle limiting block 206 and the buckle 210 are buckled to stop moving, and the sensor sensing sheet 80 is sensed to start the test.
