The reset structure further comprises at least one second elastic element 281 disposed between the actuator 274 and the first movable element 271 for driving the first movable element 271 to reset; in this embodiment, an extending portion 2718 is disposed between two opposite nesting pieces 2714 of the first moving member 271 in the return structure, the extending portion 2718 is disposed with a recessed yielding portion 2719, the return structure is disposed with a pillar 282 at a position corresponding to the yielding portion 2719 of the third member 2743 of the actuator 274, the pillar 282 is sleeved with a second elastic member 281 and a blocking block 283, one surface of the blocking block 283 abuts against the extending portion 2718 of the first moving member 271 to support the first moving member 271, and the other surface of the blocking block 283 abuts against the second elastic member 281.

In the test sequence, after the limit piece 275 of the crimping mechanism is limited by the bearing, the second movable piece 272 and the first movable piece 271 can be limited, and the design of the stop limit piece 275 can be designed according to the operation requirement, and at least one stop part is arranged on the test base 232, the support plate 22 or the frame 26 and at a position corresponding to the limit piece 275; for example, when the position-limiting member 275 is disposed in the Y direction, a stopping member, which is a blocking piece, may be disposed at a position of the testing seat 232 or the supporting plate 22 corresponding to the position-limiting member 275; for example, when the position-limiting member 275 is disposed in the Z direction, a stopping member as a stopping groove may be disposed at a position of the frame 26 corresponding to the position-limiting member 275. In this embodiment, the testing base 232 is provided with a blocking component 2324 extending in the Y direction and being a blocking piece at a position opposite to the limiting component 275, the blocking component 2324 and the testing base 232 may be integrally formed or may be separate elements, and the actuator 274 may have a suitable distance between the limiting component 275 and the blocking component 2324 in an unactuated state.

Referring to fig. 4, 6 and 7, the modular testing apparatus 20 of the present invention is light and easy to carry, and can be conveniently placed on a carrier (such as a laboratory table or a small work table), and the carrier 21 of the modular testing apparatus 20 can also be positioned on the carrier by a positioning element (such as a bolt or a positioning pin); in the present embodiment, the modular testing apparatus 20 is locked to the table of the small work table 30. During testing, the driving unit drives the carrier plate 22 of the testing unit to move out of the testing area 213 of the carrier 21 in the X direction by the motor 251 through the pulley set 252, and since the limiting member 275 of the crimper is not attached to the blocking member 2324 of the testing seat 232, the carrier plate 22 can carry a plurality of testing seats 232 of a batch to move out of the testing area 213 synchronously and is located outside the carrier 21, so that a conveyor (not shown) can move a plurality of electronic components to be tested of a batch into the testing seats 232; then, the motor 251 drives the carrier plate 22 via the pulley set 252 to carry a batch of test sockets 232 with electronic devices to be tested into the test area 213.

Referring to fig. 8 and 9, since the test seat 232 is opposite to the compression joint device and the stopper 2324 is located above the limit piece 275 of the compression joint device, during compression, the air channel 2717 of the compression joint device inputs air into the air chamber 2716 of the first movable piece 271, the air in the air chamber 2716 pushes the first movable piece 271 and the second movable piece 272 to move reversely along the operation axis L, the first movable piece 271 drives the compression joint device 273 to move downward in the Z direction synchronously, and if the second positioning part 2733 of the compression joint device 273 and the first positioning part 2323 of the test seat 232 have a slight difference, the second positioning part 2733 of the compression joint device 273 abuts against the stopper surface 2322 of the test seat 232; because the gas in the air chamber 2716 cannot push the crimping piece 273 to continuously move downwards, in the state that the gas is continuously input into the air chamber 2716, the gas can push the second movable piece 272 to reversely move upwards along the operation axis L in the Z direction, the second movable piece 272 pushes the actuator 274 and the second adjusting piece 277 to float upwards in the Z direction, and the second movable piece 272 drives the first movable piece 271 and the crimping piece 273 to move in the Y direction by using the second floating part 2771 of the second adjusting piece 277 to float and move in the Y direction along the first floating part 2761 of the first adjusting piece 276, so as to finely adjust the position of the crimping piece 273, and the second positioning part 2733 of the crimping piece 273 aligns to the first positioning part 2323 of the test seat 232.

However, when the actuator 274 moves upward in the Z direction, the third member 2743 drives the limiting member 275 to move synchronously, so that the limiting member 275 abuts against the stopper 2324 of the test seat 232 to limit the actuator 274, since the actuator 274 is connected to the second movable member 272 and also synchronously limits the second movable member 272, when the air chamber 2716 maintains a predetermined pressure, the gas in the air chamber 2716 pushes the first movable member 271 to drive the pressing member 273 to move downward in the Z direction along the working axis L, so that the second positioning member 2733 of the pressing member 273 is inserted into the first positioning member 2323 of the test seat 232, and the first movable member 271 receives the downward pushing force of the gas in the air chamber 2716, thereby effectively preventing the first movable member 271 and the pressing member 273 from moving reversely along the working axis L, not only enabling the pressing portion 2731 of the pressing member 273 to smoothly press the electronic component, but also enabling the pressing member 273 to press the electronic component reliably with the predetermined pressing force, thereby improving the testing quality.
