In addition, specifically, the resilient member 44 is disposed on the supporting plate 41 and elastically abuts against the mounting seat 42, so as to separate the mounting seat 42 and the supporting plate 41 from each other, and meanwhile, the resilient member 44 is also used to support the mounting seat 42, in practical cases, the resilient member 44 may be a rubber cylinder or a silica gel cylinder, in this embodiment, the resilient member 44 is a rubber cylinder, and the rubber cylinder is disposed in the center of the mounting seat 42 and is used to support the mounting seat 42. When the second fixture body 5 moves towards the first fixture body 4, the second fixture body 5 pushes the mounting seat 42 to move along the length direction of the two guide connecting rods 43, so as to compress the resilient member 44, that is, the mounting seat 42 is driven by the second fixture body 5 to move towards the supporting plate 41, so as to compress the resilient member 44.
In addition, as shown in fig. 8 and 9, the electrical connection assembly is disposed on the supporting plate 41, and a portion of the electrical connection assembly is exposed on a side of the supporting plate 41 away from the second fixture body 5 for electrically connecting with an upper computer, and another portion of the electrical connection assembly is exposed on a side of the supporting plate 41 facing the second fixture body 5 for penetrating through the mounting seat 42 and abutting against the power supply terminal and the signal terminal on the motherboard 2 when the second fixture body 5 moves to a predetermined position in a direction of the first fixture body 4. Because the staff places mainboard 2 in recess 421 after, can adjust the position of mainboard 2 for on mainboard 2 was placed the exact position, if just switch on with the electrical connection subassembly electrical property in mainboard 2 was placed recess 421, then in the adjustment process, can make contact failure between electrical connection subassembly and the mainboard 2, thereby lead to mainboard 2 to be damaged, and the staff is when adjusting mainboard 2, electrical connection subassembly and mainboard 2 support the end and can rub with mainboard 2, thereby scrape out mainboard 2.

When the elastic component 55 is in a natural state, the position of the pressing block 53 is higher than the position of the adapting circuit board 11, and when the first fixture body 4 pushes the pressing block 53 to move along the length direction of the two guiding connecting rods 43, and the elastic component 55 is compressed, the surface of one side of the pressing block 53, which faces the first fixture body 4, is flush with the surface of one side of the adapting circuit board 11, which faces the first fixture body 4, that is, the pressing block 53 is firstly contacted with the main board 2, and is buffered by the elastic component 55 at the back of the pressing block 53, so that when the metal feed area 12 on the adapting circuit board 11 is abutted against the antenna elastic sheet 21, the adapting circuit board 11 and the main board 2 cannot be subjected to too large impact force, and therefore, the adapting circuit board 11 and the main board 2 can be prevented from being damaged.
In addition, as shown in fig. 14, in an actual situation, the first jig body 4 can be placed on one support 6, the test jig further includes two oil cylinders 7, the two oil cylinders 7 are disposed on the supports 6 on both sides of the first jig body 4 along any direction, the ejector rods of the two oil cylinders 7 are both fixedly connected with the cover plate 51 in the second jig body 5, and the ejector rods extend out or retract, so as to drive the second jig body 5 to move towards a direction close to or away from the first jig body 4.
