3. The surge arrester test bracket according to claim 2, characterized in that, The rotating lever further includes a connecting block disposed at one end of the lever body near the locking member. The connecting block has locking ends formed on both opposite end faces along the first direction. A first slot is formed on one locking end, and a second slot is provided on the other locking end. The locking member includes a bracket, a first locking block, and a second locking block. The bracket is connected to the support plate and has a first sidewall and a second sidewall opposite to the first sidewall. The first latching block is movably connected to the first sidewall, and a first tension spring connects the first latching block to the side of the first sidewall opposite to the second sidewall. The second latching block is movably connected to the second sidewall, and a second tension spring connects the second latching block to the side of the second sidewall opposite to the first sidewall. When the rotating pull rod is in the locking position, under the action of the first tension spring, the end of the first locking block near the second side wall is locked into the first slot, and under the action of the second tension spring, the end of the second locking block near the first side wall is locked into the second slot. When the rotating pull rod is in the unlocking position, under the action of external force, the first locking block is pulled out of the first slot, and under the action of external force, the second locking block is pulled out of the second slot.

4. The surge arrester test bracket according to claim 3, characterized in that, The locking component also includes a push block connected to the bracket, and a compression spring is connected between the push block and the bracket. Under the action of the compression spring, the push block abuts against the bottom surface of the connecting block.

5. The surge arrester test bracket according to any one of claims 1 to 4, characterized in that, The surge arrester test bracket also includes a connector movably connected to the main frame and a base plate connected to the connector. The base plate is located on the side of the main frame away from the support plate. The connector drives the base plate to move. The base plate has a storage position and a support position. When the base plate is in the storage position, the distance between the bottom surface of the base plate and the support plate is less than the distance between the lowest point of the roller and the support plate. When the base plate is in the support position, the distance between the bottom surface of the base plate and the support plate is greater than the distance between the lowest point of the roller and the support plate.

6. The surge arrester test bracket according to claim 5, characterized in that, The connector includes a spiral tube, and a first screw is connected to the main frame. The surge arrester test bracket also includes a driving component. The output end of the driving component drives the first screw to rotate inside the spiral tube, and the base plate moves between the support station and the storage station through the spiral tube.

7. The surge arrester test bracket according to claim 6, characterized in that, A control panel is also provided on the side of the main frame, and the control panel is electrically connected to the drive component.

8. The surge arrester test bracket according to claim 6, characterized in that, The main frame includes a storage box disposed on the side of the support plate away from the placement space. The storage box contains a box for storing the experimental equipment. The spiral tube passes through the bottom wall of the storage box and extends into the storage box.
