The adjustment block 605 is fixedly connected to the adjustment frame 604 on the side close to the adjustment frame 604.

[0028] In this embodiment: by providing a limiting groove 8 on the top of the fixing seat 1, the fixing seat 1 can conveniently limit the electronic board 4 through the limiting groove 8, so that the side of the adjusting block 605 close to the adjusting frame 604 is fixedly connected to the adjusting frame 604, and the adjusting frame 604 can be adjusted and moved inside the pressing cover 2 through the adjusting block 605, so that the pressing cover 2 can conveniently drive the protective pad 601 to move to the top of the electronic board 4 through the adjusting frame 604, limit the electronic board 4, and connect the surface of the electronic component 3 and the test tool through the pressing groove 603, so that the protective pad 601 can conveniently limit the test tool through the connecting groove 602, thereby facilitating the testing of the electronic component 3.

[0029] Specifically, such as Figure 2 、 Figure 5 As shown, first limiting pads 701 are provided on the front and rear sides of the inner wall of the limiting groove 8 , and the top of the first limiting pad 701 is fixedly connected to the limiting plate 702 .

[0030] Specifically, such as Figure 2 、 Figure 5 As shown, both sides of the inner wall of the limiting groove 8 are slidably connected with sliding plates 703, and the opposite sides of the two sliding plates 703 are fixedly connected with second limiting pads 705.

[0031] Specifically, such as Figure 2 、 Figure 5 As shown, two limiting springs 704 are fixedly connected to opposite sides of the two sliding plates 703 , and the side of the limiting spring 704 close to the limiting groove 8 is fixedly connected to the inside of the limiting groove 8 .

[0032] In this embodiment, by fixing the limiting spring 704 close to the limiting groove 8 and the inside of the limiting groove 8, the sliding plate 703 can fix electronic boards 4 of different specifications through the limiting spring 704, thereby achieving the effect of fixing electronic boards 4 of different specifications.

[0039] Working principle: When testing the electronic components 3 on different electronic boards 4, the electronic board 4 is moved to the inside of the limiting groove 8, so that the first protective pad 601 limits the electronic board 4 through the limiting plate 702, so that the electronic board 4 can be conveniently driven by the second limiting pad 705 to move the sliding plate 703 to a suitable position, and the sliding plate 703 can be conveniently fixed to the electronic board 4 through the limiting spring 704, and then the pressing cover 2 is driven by the adjusting block 605 to move the adjusting frame 604, so that the pressing cover 2 is limited by the limiting column 5 and drives the protective pad 601 to move to the top of the electronic board 4, so that the fixing handle 11 is pressed against the pressing cover through the gasket 10. 2 is locked, and at the same time, the surface of the electronic component 3 and the test tool are connected through the pressing groove 603, so that the protective pad 601 can limit the test tool through the connection groove 602, thereby facilitating the testing of the electronic component 3. This solves the existing problem of traditional ceramic-metal surface-mount devices, in which solder paste is evenly applied to the bottom of the device during use, and then the device is fixed on the PCB after the solder is cured at high temperature. However, if the device is to be shipped and tested, welding cannot be performed, otherwise the appearance will not meet the shipping standards. Generally, for the shipment test of surface-mount devices, a special socket needs to be designed, which is expensive and complex to design.
