[0022] First, the disconnector switch to be tested is placed between the two clamping plates 201 on the sliding base 200. Then, the clamping plates 201 on both sides are driven to move towards each other to clamp and fix the disconnector switch. Finally, the sliding base 200 is driven to slide along the base plate 100, which can smoothly and quickly push the disconnector switch into the testing equipment, solving the problem of inconvenience in fixing disconnector switches in traditional testing equipment.

[0023] like Figures 1-3 As shown, the fixing mechanism also includes a lead screw 202 rotatably connected to the sliding seat 200.
