The base and the tray are connected through the bracket. The tray is built into the base. A large opening is provided at the top of the base so that the studs of the tray can be higher than the top surface of the base to facilitate the installation of the motherboard. The wrench is also installed in the base. The connecting rod is used to connect the wrench and the tray. Through corresponding limiting measures, when the wrench is turned, the connecting rod will drive the tray to move forward and backward by a certain distance, so that the motherboard installed horizontally on the tray and the backplane installed vertically at the rear of the test card track holder form a plug-in and pull-out relationship. The designed rotating heat sink bracket carries a heat sink, which can contact and disengage with the chip on the motherboard by rotating. The integrated card holder integrates multiple test boards together, without the need to plug and unplug the boards multiple times.

[0018] By turning the wrench of this device, the mainboard and the backplane can be quickly matched and separated. Compared with the original outer frame of the equipment for testing, it eliminates the tedious steps of disassembling the cover, installing the backplane multiple times, and installing the mainboard multiple times at a large angle and with great difficulty (a certain inclination is required for installing the mainboard, and there are many precautions for matching). Simply place the mainboard on the tray and tighten it with hand-tight screws (hand-tight screws are more efficient and can fix the mainboard without tools), then turn the wrench or pull the handle to drive the mainboard to move in coordination, and the efficiency of installing and removing the mainboard is increased by nearly 10 times. The rotating heat sink design no longer requires the trouble of installing and removing the heat sink from the mainboard. The integrated card holder increases the test efficiency of the single board by 2.5 times. The above beneficial effects greatly save labor costs. BRIEF DESCRIPTION OF THE DRAWINGS
