[0046] The working principle of the utility model is as follows: when in use, the equipment is decelerated by the reduction motor 103. When the equipment stops, the staff starts the double-axis motor 202. The output ends on both sides of the double-axis motor 202 drive the two transmission rods 203 to rotate. When the two transmission rods 203 rotate, they drive the two first bevel gears 204 to rotate. When the two first bevel gears 204 rotate, they drive the two second bevel gears 205 to rotate. When the two second bevel gears 205 rotate, they drive the two bidirectional screw rods 206 to rotate.

When the positioning plate 210 moves in the reverse direction, it drives the four rubber anti-skid pads 211 to move in the reverse direction. When the rubber anti-skid pads 211 move to the inner cavity of the track 101 and contact the track 101, the movable base 102 can be limited to prevent the movable base 102 from sliding. When the staff needs to maintain the reduction motor 103, the push rod 108 is pushed. The push rod 108 drives the extrusion block 107 to move when it moves. The extrusion block 107 stretches the tension spring 106 when it moves, and drives the adjustment block 109 to move upward. When the adjustment block 109 moves upward, it squeezes the return spring 111 and drives the limiting plate 110 to move upward. When the limiting plate 110 moves upward, it drives the fixing plate 112 and the insertion rod 113 to move upward. When the insertion rod 113 moves out of the mounting hole 105, the staff can remove the reduction motor 103 from the top of the movable base 102, thereby improving the maintenance efficiency of the staff.
