The connecting piece 278 is a bolt, and locks the second adjusting piece 277 and the first member 2741, so that the first member 2741 drives the second floating portion 2771 of the second adjusting piece 277 to separate from the first floating portion 2761 or to perform floating displacement along the first floating portion 2761 to release the locking, and the second movable piece 272 drives the first movable piece 271 and the pressing piece 273 to perform floating displacement (such as X-Y direction or horizontal angle Θ), so as to finely adjust the placement position or placement angle of the pressing piece 273.

The reset structure is characterized in that a first elastic member 279 is arranged between the first adjusting member 276 and the actuator 274 or the second movable member 272 to drive the actuator 274 to reset; in this embodiment, the second adjusting member 277 has a second through hole 2772 for passing through the first elastic member 279, one end of the first elastic member 279 abuts against the first member 2741 of the actuator 274, and the other end abuts against a cover plate 280 locked to the first adjusting member 276 to drive the actuator 274 to return.

The returning structure further comprises at least one second elastic member 281 disposed between the actuator 274 and the first movable member 271 for driving the first movable member 271 to return; in this embodiment, an extending portion 2718 is disposed between two corresponding engaging blocks 2714 of the first movable member 271 in the returning structure, a recess-shaped abdicating portion 2719 is disposed on the extending portion 2718, a pillar 282 is disposed at a position of the third member 2743 of the actuator 274 corresponding to the abdicating portion 2719 in the returning structure, the pillar 282 is sleeved on the second elastic member 281 and the blocking block 283, one surface of the blocking block 283 abuts against the extending portion 2718 of the first movable member 271 to support the first movable member 271, and the other surface of the blocking block 283 abuts against the second elastic member 281.

However, in the test sequence, after the limiting piece 275 of the crimping mechanism is limited in bearing, the second movable piece 272 and the first movable piece 271 can be limited, and the design of the stopping limiting piece 275 can be determined according to the operation requirement, and at least one stopping component is arranged on the test seat 232, the bearing plate 22 or the frame 26 and opposite to the position of the limiting piece 275; for example, when the limiting member 275 is configured in the Y direction, a blocking member serving as a blocking piece may be disposed at a position of the test seat 232 or the carrier plate 22 corresponding to the limiting member 275; for example, when the limiting member 275 is disposed in the Z direction, a blocking member serving as a blocking slot may be disposed at a position of the frame 26 corresponding to the limiting member 275, and the foregoing exemplary design can block the limiting member 275, which is not limited to the embodiment. In this embodiment, the test seat 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 test seat 232 may be integrally formed or be separate components, and the actuator 274 is in an unactuated state, so that the limiting component 275 and the blocking component 2324 have a proper distance.

Referring to fig. 4, 6 and 7, the modular test apparatus 20 of the present invention is portable and easy to carry, and can be conveniently placed on a carrier (e.g. a laboratory table or a small-sized table), and the carrier 21 of the modular test apparatus 20 can also be positioned on the carrier by positioning elements (e.g. pins or positioning pins); in this embodiment, the modular test apparatus 20 is locked to the table board of the small-sized work table 30. During testing, the driving unit drives the carrier 22 of the testing unit to move out of the testing area 213 of the carrier 21 in the X-direction displacement by the motor 251 through the belt pulley set 252, and the limiting member 275 of the press-connector is not attached to the stopper 2324 of the testing seat 232, so that the carrier 22 can carry a batch of a plurality of testing seats 232 to synchronously move out of the testing area 213, and is located outside the carrier 21, so that a conveyor (not shown) can move a batch of a plurality of electronic components to be tested into the testing seats 232; then, the motor 251 drives the carrier 22 to carry a lot of test seats 232 with electronic devices to be tested into the test area 213 through the belt pulley set 252.

Referring to fig. 8 and 9, since the test socket 232 is opposite to the press-connector and the stopper 2324 is located above the stopper 275 of the press-connector, during pressing, the air passage 2717 of the press-connector inputs air into the air chamber 2716 of the first movable member 271, the air in the air chamber 2716 pushes the first movable member 271 and the second movable member 272 to move reversely along the operation axis L, the first movable member 271 drives the press-connector 273 to move downwards in the Z direction synchronously, if the second positioning member 2733 of the press-connector 273 and the first positioning member 2323 of the test socket 232 have a small position difference, the second positioning member 2733 of the press-connector 273 will abut against the stopper 2322 of the test socket 232; because the gas in the air chamber 2716 cannot push the crimping member 273 to move downward continuously, in the state that the gas is continuously input into the air chamber 2716, the gas pushes the second movable member 272 to move upward reversely along the Z direction of the operation axis L, the second movable member 272 pushes the actuator 274 and the second adjusting member 277 to float upward along the Z direction, the second movable member 272 uses the second floating portion 2771 of the second adjusting member 277 to move in a floating manner along the first floating portion 2761 of the first adjusting member 276, and drives the first movable member 271 and the crimping member 273 to move in a Y direction, so as to finely adjust the position of the crimping member 273, and the second positioning member 2733 of the crimping member 273 is aligned with the first positioning member 2323 of the test seat 232.

However, when the actuator 274 moves upward in the Z direction, the third member 2743 drives the limiter 275 to move synchronously, so that the limiter 275 abuts against the stopper 2324 of the test socket 232 to limit the actuator 274, and because the actuator 274 is connected to the second movable member 272 and also synchronously limits the second movable member 272, under the condition that the air chamber 2716 maintains a certain preset air pressure, the air of the air chamber 2716 pushes the first movable member 271 to drive the crimping member 273 to move downward in the Z direction along the working axis L, so that the second positioning member 2733 of the crimping member 273 is inserted into the first positioning member 2323 of the test socket 232, and the first movable member 271 bears the downward thrust of the air chamber 2716, thereby effectively preventing the first movable member 271 and the crimping member 273 from moving reversely along the working axis L, not only the pressing portion 2731 of the crimping member 273 can be smoothly crimped to the electronic component, but also the crimping member 273 can be crimped to the electronic component with the preset pressing force, and further improving the test quality.
