As the preferred technical scheme, supporting component is including installing two tracks on the bottom plate to and fixed clamping jaw, fixed clamping jaw's bottom slidable mounting is on the track, connects through the connecting rod between the fixed clamping jaw of adjacent side, and a clamping cylinder is all installed to two track outsides of same side, and the clamping cylinder is ejecting and promote the connecting rod to take fixed clamping jaw to remove, and the fixed clamping jaw of adjacent both sides presss from both sides tightly by the test product of being awaited measuring of jack-up.

As the preferable technical scheme, install a lower air cylinder at the top of roof, the cylinder pole of lower air cylinder passes the roof and is connected with the lifter plate, lower air cylinder is ejecting downwards to remove the test fixture of lifter plate bottom to the product that awaits measuring and test.

As the preferable technical scheme, the upper jacking assembly comprises an upper jacking cylinder, the upper jacking cylinder is arranged at the bottom of the bottom plate, a cylinder rod of the upper jacking cylinder penetrates through the upper end face of the bottom plate, and the upper jacking cylinder ejects the product to be tested arranged on the two tracks into the middle clamping cavity of the supporting assembly.

As the preferable technical scheme, the product to be tested comprises a carrier plate and a PCB (printed circuit board) arranged on the carrier plate, and the PCB is arranged on a conveying rail at the bottom through the carrier plate.

The beneficial effects of the invention are as follows: the invention overcomes the problems of long waiting time, low operation efficiency, complex structure, high cost and the like of the prior operation mode, and can simultaneously and independently operate by connecting a plurality of same or similar devices in series.

Drawings
