[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 Figure 2 As shown, a withdrawable power distribution switch cabinet includes a switch cabinet body 2, a switch cabinet top cover 1 is provided at the upper end of the switch cabinet body 2, a switch cabinet base 3 is provided at the lower end of the switch cabinet body 2, a drawer unit 4 is provided on the switch cabinet body 2, a notch 7 is provided at the bottom of the drawer unit 4, a driving mechanism 5 is provided below the drawer unit 4 in the switch cabinet body 2, a push-pull mechanism 6 is fixedly installed on the driving slider 504, and the push-pull mechanism 6 can be driven to move forward and backward by the driving mechanism 5, thereby individually or centrally controlling the drawer unit 4.

[0020] like Figure 3 As shown, the driving mechanism 5 includes a driving motor 501 fixed in the switch cabinet body 2, a ball screw 503 is provided at the output end of the driving motor 501, a ball nut 506 is provided on the ball screw 503, a driving slider 504 is fixedly installed on the ball nut 506, a coupling 502 is provided at the output end of the driving motor 501, one end of the ball screw 503 is connected to the output end of the ball screw 503 through the coupling 502, a bearing is provided at the other end of the ball screw 503, and the other end of the ball screw 503 is movably installed in the switch cabinet body 2 through the bearing, a docking groove 505 is provided on the driving slider 504, a positioning frame 605 is installed on the driving slider 504 through the docking groove 505, and the driving slider 504 is movably installed below the drawer unit 4 through the ball screw 503.

[0021] Specifically, the ball screw 503 can be driven to rotate by driving the motor 501. During the rotation of the ball screw 503, it will drive the ball nut 506 to move forward and backward along the ball screw 503, and then drive the driving slider 504 on the ball nut 506 to move forward and backward. After the driving slider 504 moves forward and backward, it will drive the push-pull mechanism 6 to move forward and backward.

[0022] like Figure 3 As shown, the push-pull mechanism 6 includes a positioning frame 605 fixed on the driving slider 504, a movable groove 604 is provided on the positioning frame 605, a movable shaft 603 is movably installed in the movable groove 604, a pushing block 601 is fixedly installed on the movable shaft 603, a torsion spring 606 is sleeved on the movable shaft 603, the movable groove 604 of the movable shaft 603 is movably installed in the positioning frame 605, the pushing block 601 is movably installed in the positioning frame 605 through the movable shaft 603, and the upper end of the pushing block 601 is embedded in the notch 7, the positioning frame 605 and the pushing block 601 are both provided with connecting holes 602, one end of the torsion spring 606 is connected to the positioning frame 605 through the connecting hole 602, and the other end of the torsion spring 606 is connected to the pushing block 601 through the connecting hole 602.
