[0006] The first stationary contact and the second stationary contact are arranged at intervals and are respectively used for wiring and connecting circuits;
[0007] The first moving contact is located between the first stationary contact and the second stationary contact and is fixed on the first main shaft assembly;
[0008] The first main shaft assembly is rotatably arranged, and is used to drive the first moving contact to overlap and conduct between the first static contact and the second static contact, or to be spaced between the first static contact and / or the second static contact after rotation. A slot is formed on the outer ring of the first main shaft assembly;
[0009] The swinging member is arranged to swing toward or away from the first spindle assembly, and the swinging member extends toward the outer ring of the first spindle assembly to form a clamping portion;
[0010] The sliding plate is slidably arranged and is formed with a toggle portion. The swinging member extends to a path where the toggle portion slides along with the sliding plate and is used to swing toward the first spindle assembly under the toggle of the toggle portion so that the clamping portion is inserted into the clamping slot to lock the rotation of the first spindle assembly.
[0011] Furthermore, an elastic member is provided, which is connected to the swing member to elastically pull the swing member to swing away from the first spindle assembly, so that the clamping portion exits the clamping slot to unlock the rotation of the first spindle assembly.
[0012] Further, there is only one clamping groove, and it is aligned with the clamping portion for insertion only when the first main shaft assembly rotates to make the first moving contact spaced from the first static contact and / or the second static contact.
[0013] Furthermore, a motor is provided, which is transmission-connected to the first spindle assembly and is used to drive the first spindle assembly to rotate.
[0014] Furthermore, the first spindle assembly has a first spindle gear, the slot is formed on the first spindle gear, and the motor shaft gear of the motor is meshingly connected to the first spindle gear.
[0015] Further, a first pre-filling static contact and a first main static contact are formed on the first static contact, and a second pre-filling static contact and a second main static contact are formed on the second static contact;
[0016] The first moving contact is located between the first pre-filling static contact and the first main static contact, and is used for overlapping and conducting with the first static contact and the second static contact from the first pre-filling static contact and the second pre-filling static contact;
[0017] The second moving contact is located between the second pre-filling static contact and the second main static contact, and is fixed on a second main shaft assembly. The second main shaft assembly is gear-engaged and connected to the first main shaft assembly, and is used to drive the second moving contact to overlap and conduct between the second pre-filling static contact and the second main static contact, or to be spaced between the second pre-filling static contact and / or the second main static contact after rotation.

[0019] Furthermore, the first moving contact radially penetrates the first main shaft assembly, and both ends extend out of the first main shaft assembly respectively, and the parts of both ends of the first moving contact extending out of the first main shaft assembly are respectively used to overlap the first stationary contact and the second stationary contact.
[0020] After adopting the above scheme, the beneficial effect of the utility model is that after the first main shaft assembly rotates, it can drive the first moving contact to overlap and conduct between the first static contact and the second static contact to achieve closing, and can also drive the first moving contact to be spaced between the first static contact and / or the second static contact to achieve opening. After the sliding plate slides, it drives the toggle portion on it to move toward the direction of the first main shaft assembly. During the displacement, the swinging piece is toggled to make the swinging piece swing toward the first main shaft assembly. The swinging piece extends toward the outer ring of the first main shaft assembly to form a clamping portion. After the swinging piece swings toward the first main shaft assembly, the clamping portion will be inserted into the clamping groove on the outer ring of the first main shaft assembly to clamp the first main shaft assembly to lock the rotation of the first main shaft assembly. Since the first main shaft assembly can no longer rotate at this time, the position of the moving contact fixed thereon is also fixed, thereby realizing the closing and opening actions of the mechanical locking circuit switch.
