Embodiment Construction
[0020] See figure 1 with figure 2 The double-acting transmission device shown in , which includes a driving rack 6 and a static arc contact rack 24 arranged in parallel and extending along the moving direction of the moving contact assembly, between the driving rack and the static arc contact rack There is a gear 22 meshing with the two gear racks for simultaneous transmission. The position of the rotating shaft of the gear is fixed. The driving rack 6 is used to be fixedly connected with the moving contact assembly, and the follower moving contact assembly is used for linear reciprocating movement. 6. The gear 22 drives the static arc contact rack 24 to perform reverse movement, and the static arc contact rack 24 is used to be fixedly connected with the static arc contact 21 and drive the static arc contact to perform linear reciprocating movement.
[0021] In this embodiment, both sides of the gear are provided with a guide plate 3 whose plate surface is parallel to the ge...
