The first fixed seat 3 has a second guide groove 10 vertically arranged on its inner side. The second test seat 5 has second guide strips 11 on both sides that cooperate with the first guide groove 7. The first fixed seat 3 has two pairs of first locking structures that lock the first test seat 3 and the second test seat 4 between the first fixed seat 3 respectively. The second fixed seat 12 is provided in front of the second test seat 5. The two ends of the second fixed seat 12 extend backward and are detachably installed on the first fixed seat 3. The middle part of the second fixed seat 12 has a second locking structure that assists in locking the second test seat 5.

[0017] In use, the test base 1 is mounted on a multi-functional test bench and electrically connected to the test bench via one end of the first conductive terminal 2. The other end of the first conductive terminal 2 is used to insert the device under test. The first test seat 4 is vertically slidably mounted between the first fixed seats 3 through the cooperation of the first guide groove 7 and the first guide bar 8. The second test seat 5 is vertically slidably mounted between the first fixed seats 3 through the cooperation of the second guide groove 10 and the second guide bar 11. After the first test seat 4 and the second test seat 5 are slid into place, they can be positioned by the corresponding first locking structure. Generally, the second test seat 5 is larger and heavier, so it can be assisted in locking by the second locking structure. Both the first test seat 4 and the second test seat 5 have circuit boards inside, and both have signal interfaces on their lower ends. The second conductive terminal 6 and the signal interface on the first test seat 4 are electrically connected to the circuit board inside, and the third conductive terminal 9 and the signal interface on the second test seat 5 are connected to the circuit board inside. The second conductive terminal 6 and the third conductive terminal 9 are used to insert the device under test, and the signal interface is electrically connected to the multi-functional test bench via a data cable. During testing, the second test seat 5 moves downward, while the first test seat 4 and test base 1 protrude, allowing for testing of concentrators. The second test seat 5 moves upward and, in conjunction with the first test seat 4 and test base 1, allows for testing of data acquisition terminals. Replacing the second test seat with another type allows for testing of energy controllers, thus achieving multi-functional testing. This invention has a simple structure and is easy to use. By sliding the first and second test seats up and down to form different test combinations when testing different devices, different devices can be tested, reducing the number of replacements and improving testing efficiency. Furthermore, the first and second test seats are detachable and replaceable, making the testing functions more diverse.

[0018] Preferably, the first locking structure includes a first locking rod 13. Two first locking rods 13 are provided on each of the first fixed seats 3. The middle part of the first locking rod 13 is connected to the first fixed seat 3 by a threaded structure. The inner end of one first locking rod 13 abuts against the first test seat 4, and the inner end of the other first locking rod 13 abuts against the second test seat 5. The outer end of the first locking rod 13 is located outside the first fixed seat 3 and is provided with a first operating part 14. By rotating the first operating part 14, the first locking rod 13 can be moved in the first fixed seat 3. When the first locking rod 13 moves inward, it can abut against the first test seat 4 or the second test seat 5 to lock the first test seat 4 or the second test seat 5, preventing the first test seat 4 and the second test seat 5 from moving downward out of the first fixed seat 3. When the first locking rod 13 moves outward, it can release the first test seat 4 or the second test seat 5, making it convenient to adjust the position of the first test seat 4 or the second test seat 5 up and down, or to conveniently remove the first test seat 4 and the second test seat 5.

The inner end of the first locking rod 13 can be located in one of the first locking holes 15. When the inner end of the first locking rod 13 is located in one of the first locking holes 15, the first test seat 4 or the second test seat 5 can be in a testing position. When the inner end of the first locking rod 13 is located in the other first locking hole 15, the first test seat 4 or the second test seat 5 can be in a non-testing position, thus achieving locking of the first test seat 4 or the second test seat 5 in both testing and non-testing states.

[0020] Preferably, the second locking structure includes a second locking rod 16, the middle of which passes through the second fixed seat 12. A spring is provided between the second locking rod 16 and the second fixed seat 12. The inner end of the second locking rod 16 abuts against the second test seat 5, and the outer end of the second locking rod 16 is located outside the front side of the second fixed seat 5 and has a second operating part 17. By pulling the second operating part 17 forward, the second locking rod 16 can move forward in the second fixed seat 12, and the inner end of the second locking rod 16 no longer abuts against the second test seat 5. When the first locking rod 13 is not locking the second test seat 5, the second test seat 5 can be moved up and down. When the second test seat 5 is in place, the second operating part 17 is released, and the second locking rod 16 returns to its original position under the action of the spring and abuts against the second test seat 5 to lock the second test seat 5, and assists the first locking rod 13 in locking the second test seat 5 together, making the fixation more secure.

[0021] Preferably, the second locking structure further includes a second locking hole 18, which is recessed on the front surface of the second test seat 5, and the inner end of the second locking rod 16 can be inserted into the second locking hole 18.
