In some embodiments, the loader 40 further comprises a lamination 44, the lamination 44 comprising a lamination portion 441 detachably covering a side of the tool 30 facing away from the platen 41. The function of the lamination portion 441 is to apply pressure with the acting direction pointing to the platen 41 to the tool 30 in the process of mounting the tool 30 to the platen 41 along the throwing direction, and to continuously apply pressure with the acting direction pointing to the platen 41 to the tool 30 after the tool 30 is mounted on the platen 41, so as to prevent the butt joint piece 21 from driving the tool 30 to shake relative to the platen 41 when the butt joint piece 60 is directly abutted against the adaptor 60 or the device 200 is directly abutted against the device 200, and maintain the postures of the tool 30 and the device 200

Referring to fig. 4 and 6, the lamination portion 441 has a plate structure, and the lamination portion 441 can move relatively close to the carrier plate 31 along a linear track perpendicular to the carrier plate 31 in a state of being parallel to the carrier plate 31. In order to enable the lamination portion 441 to precisely move along a linear track perpendicular to the carrier plate 31, the tooling 30 further includes a second guide portion 32 fixedly disposed on the carrier plate 31, and the lamination portion 44 further includes a gland guide sleeve 444 fixedly disposed on the lamination portion 441, wherein a sliding guide fit formed between the second guide portion 32 and the gland guide sleeve 444 is performed along a direction perpendicular to the carrier plate 31 and parallel to a line where an arrow S in fig. 5 is located. Of course, the positions of the second guide 32 and the gland guide 444 may be interchanged.

As shown in fig. 2 to 3 and 5, in some embodiments, the platen 41, the carrier 31, and the lamination portion 441 are stacked in order in a direction perpendicular to the carrier 31. The preparation required before starting testing the device under test 200 includes: firstly, the device 200 to be tested is placed at the material level 301, so that the device 200 to be tested and the adapter 60 form pre-connection, then the lamination part 441 is covered on one side of the carrier plate 31, which is away from the platen 41, then the lamination part 441, the carrier plate 31 and the device 200 to be tested synchronously move close to the platen 41 along the throwing direction until the carrier plate 31 is fixedly carried on the platen 41, and finally the platen 41 and the carrier plate 31 are fixed through the positioning piece 43 and the locking piece 33.

Optionally, in the process that the tool 30 carries the device 200 to be tested and moves along the throwing direction, in order to prevent the butting piece 21 from exerting a force on the adapting piece 60, so that the adapting piece 60 and the device 200 to be tested loose or deflect relative to the carrier plate 31, the stacking piece 44 further includes a pressing block 445 fixedly arranged at the stacking portion 441, and the pressing block 445 is fixedly arranged at one side of the stacking portion 441 relatively close to the carrier plate 31 and the platen 41. When the lamination portion 441 is covered on the side of the carrier 31 away from the platen 41, the pressing block 445 abuts against the device under test 200, so that the adaptor 60 and the device under test 200 are clamped and fixed by the carrier 31 and the pressing block 445. With this arrangement, the stacking piece 44 can simultaneously apply pressure to the carrier plate 31 and the device under test 200 with the direction of action directed toward the platen 41, and can be connected to the butt piece 21 with the device under test 200 kept in a stable posture.

Optionally, in the embodiment shown in fig. 2 to 3, the stacking member 44 further includes a base 443 fixed to the platen 41 and an anti-falling portion 442 movably connected to the base 443, where an end of the anti-falling portion 442 opposite to the base 443 forms an anti-falling hook, and the anti-falling hook can move relative to the platen 41 in a direction approaching and separating from the platen 41. When the lamination portion 441 is fixedly covered on the carrier 31 and the carrier 31 is fixedly supported on the platen 41, the anti-unhooking hook can relatively move close to the platen 41 so as to hook one side of the lamination portion 441 away from the carrier 31. Of course, in other embodiments, the base 443 may be fixed to the lamination portion 441, and the anti-unhooking hook may be hooked to the platen 41 when the lamination portion 441 is fixedly covered on the carrier 31 and the carrier 31 is fixedly supported on the platen 41.
