2. The structural design of the swinging shaft adopts a double-arm (swinging arm and driven arm) double-fulcrum structure. Reasonable stress and small resistance.

3. A sliding sleeve guide rod of the movable spring mechanism is arranged at the top end of the device and is waterproof and antifouling, and the device occupies a good working position.

4. By adopting the folding operating handle, the height dimension can be extended and contracted, the operation is convenient, and the occupied height of the facility is reduced.

5. The sliding sleeve adopts a linear bearing to enable the movable spring mechanism to be more sensitive and light.

6. The push-pull connecting rod adopts a joint bearing, can be more suitable for the space curve stroke requirement of the turnout operation process, and has the advantages of free transmission and no obstruction of blocking.

7. The shaft support adopts a box body combination type, so that the structure is lighter.

The invention has reasonable design, compact structure of the switch device, reliable positioning, convenient installation and convenient operation, is further perfection and improvement on underground auxiliary transportation system facilities and has good practical application value.
