A sleeve rod 17 is welded to both sides of the bottom of the placement table 7. One end of the support rod 16 is movably sleeved on the outside of the sleeve rod 17. A second motor 19 is installed on the outside of the test cabinet 1 through bolts. The output end of the second motor 19 extends into the inside of the base 15 and is fixedly connected to one end of the second double-threaded lead screw 14. A tester 11 is installed on the top of the test cabinet 1.

[0021] Specifically, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, the rotation of the output end of the second motor 19 can drive the second double-threaded lead screw 14 to rotate. Since a slider 6 is sleeved on the outer sides of both ends of the second double-threaded lead screw 14 through thread engagement, the rotation of the second double-threaded lead screw 14 can drive the two sliders 6 to slide relatively along the installation direction of the second double-threaded lead screw 14. Since a support rod 16 is movably sleeved on the top ends of the two sliders 6 respectively, and one end of the support rod 16 is slidably sleeved on the outer sides of the sleeve rods 17 installed on both sides of the bottom of the placement table 7, by controlling the forward and reverse rotation of the output end of the second motor 19, the placement table 7 can be driven to extend out of the interior of the test cabinet 1 or be received into the interior of the test cabinet 1. Therefore, during the operation, the placement table 7 can be extended out of the interior of the test cabinet 1, and then it is convenient for the operator to place the battery stack above the placement table 7. Subsequently, by rotating the output end of the second motor 19, the placement table 7 together with the battery stack installed on the top is received into the interior of the test cabinet 1 for testing. With this device, it is possible to prevent the operator's limbs from entering the interior of the test cabinet 1 to take and place the battery stack, improving the convenience of using the device and facilitating the operator to take and place the battery stack.

[0022] Embodiment 2: Four fixed casters 2 are movably installed at the bottom of the test cabinet 1, and the four fixed casters 2 are respectively located at the four corners of the bottom of the test cabinet 1. A fixed block 4 is welded on the outer side of the test cabinet 1, and a worm 5 is connected to the inside of the fixed block 4 through thread engagement. An anti-slip plate 3 is movably installed at the bottom of the worm 5. Two cabinet doors 9 are hinged on one side of the test cabinet 1, and a pull rod 8 is welded on one side of each of the two cabinet doors 9 respectively. A first double-threaded lead screw 10 is movably installed inside the placement table 7, and a clamping plate 12 is sleeved on the outer sides of both ends of the first double-threaded lead screw 10 through thread engagement.

A first motor 13 is installed on one side of the placement table 7, and the output end of the first motor 13 extends into the interior of the placement table 7 and is fixedly connected to one end of the first double-threaded lead screw 10.

[0023] Specifically, as Figure 1 、 Figure 2 、 Figure 3 and Figure 4As shown in the figure, since four fixed casters 2 are movably installed at the bottom of the test cabinet 1, the entire device can be conveniently moved through the four fixed casters 2. Since a fixed block 4 is welded to the outside of the test cabinet 1, and a worm 5 is connected to the inside of the fixed block 4 through thread engagement, and an anti-slip plate 3 is movably installed at the bottom end of the worm 5, by rotating the worm 5, the anti-slip plate 3 can be driven to move downward, so that the bottom end of the anti-slip plate 3 contacts the ground, thus ensuring the stability of the device during use. Since two cabinet doors 9 are hinged to one side of the test cabinet 1, and a pull rod 8 is installed on one side of the cabinet door 9, the cabinet door 9 hinged to one side of the test cabinet 1 can be opened through the pull rod 8. By rotating the output end of the first motor 13, the first double-threaded lead screw 10 can be driven to rotate. By rotating the first double-threaded lead screw 10, the two clamping plates 12 can be driven to slide relatively along the installation direction of the first double-threaded lead screw 10, so as to clamp the battery stack placed above the placement table 7, thus ensuring the stability when moving the battery stack.

[0024] Working principle: During use, open the two cabinet doors 9 hinged to one side of the test cabinet 1. Subsequently, by rotating the output end of the second motor 19, the second double-threaded lead screw 14 can be driven to rotate. Since two sliders 6 are respectively sleeved on the outside of both ends of the second double-threaded lead screw 14 through thread engagement, by rotating the second double-threaded lead screw 14, the two sliders 6 can be driven to slide relatively along the installation direction of the second double-threaded lead screw 14. Since a support rod 16 is movably sleeved on the top end of each of the two sliders 6, and one end of each support rod 16 is slidably sleeved on the outside of the sleeve rods 17 installed on both sides of the bottom of the placement table 7, by controlling the forward and reverse rotation of the output end of the second motor 19, the placement table 7 can be driven to extend out of the inside of the test cabinet 1 or be received into the inside of the test cabinet 1. Therefore, during the operation, the placement table 7 can be extended out of the inside of the test cabinet 1, and then it is convenient for the operator to place the battery stack above the placement table 7. Subsequently, by rotating the output end of the first motor 13, the first double-threaded lead screw 10 can be driven to rotate. By rotating the first double-threaded lead screw 10, the two clamping plates 12 can be driven to slide relatively along the installation direction of the first double-threaded lead screw 10, so as to clamp the battery stack placed above the placement table 7, thus ensuring the stability when moving the battery stack. Subsequently, by rotating the output end of the second motor 19, the placement table 7 together with the battery stack installed on the top can be received into the inside of the test cabinet 1 for testing.
