The locking member 60 can pass through the exposed locking hole 23 to further lock the locking slider 30. By means of the locking hole 23 and the locking piece 60, the handle 20 can be locked in the locking groove 12 more reliably without being rotated. The handle 20 has a cavity 24 that opens in a direction opposite the first direction D1.

The handle 20 further includes a first resilient member 25. In an exemplary embodiment, the first resilient member 25 is a helical compression spring, but is not limited thereto. The first elastic member 25 is disposed in the cavity 24 with one end abutting against a wall bounding the cavity 24 and the other end extending in a natural state to cover the locking hole 23 and abutting against the locking slider 30. The first elastic member 25 can be compressed to expose the locking hole 23 during the movement of the locking slider 30 along the sliding groove 22. When unlocked, the locking slider 30 is automatically reset by the elastic force of the first elastic member 25.

The switch member of the switch device is arranged in the electrical cabinet, one end of a square shaft of the switch member is arranged in the switch member, and the other end of the square shaft passes through the first shaft hole 11, the driving hole 41, the third shaft hole 51 and the second shaft hole 21 and is inserted into a cabinet door rotating handle arranged on a cabinet door of the electrical cabinet so as to drive the square shaft to rotate under the rotation of the cabinet door rotating handle.

The utility model provides a switching device leans on each other through the inside first rotating part 40 of its handle assembly and second rotating part 50 to drive first rotating part 40 and rotate with the drive square shaft and rotate, leans on the state separation back with the second rotating part 50 follow and first rotating part 40, and handle 20 rotates and can not drive the square shaft and rotate, and the square shaft can be under the operation of the cabinet door turning handle of regulator cubicle with switching device separating brake or combined floodgate and do not receive handle assembly's influence. The handle 20 is locked to the locking groove 12, and the locking piece 60 is passed through the locking hole 23 of the handle 20 through the locking hole 23 to securely lock the handle 20 against rotation. If the handle 20 needs to be turned to close the switch, the locking piece 60 needs to be opened by a key, and through the confirmation action, the electric shock of a maintainer caused by other personnel operating the handle 20 to the switch-on position by mistake is avoided.

Fig. 3 is a schematic view of the handle assembly shown in fig. 1 with the first and second rotatable portions 40 and 50 in an abutting state. Fig. 4 is a cross-sectional view taken along the direction IV-IV of fig. 3. Referring to fig. 3 and 4, the second rotating part 50 is provided with three abutting parts 52. When the handle 20 is pressed down in the first direction D1, the second elastic member 70 is compressed, and the second rotating portion 50 moves to a position where the three abutting portions 52 thereof are in contact with the first rotating portion 40, respectively, i.e., an abutting position. The second rotating part 50 is rotated by rotating the handle 20, and the first rotating part 40 is driven to rotate by the three abutting parts 52, so that the square shaft is driven to rotate, and the switching-on and switching-off of the switching device are completed. In other exemplary embodiments, the abutments 52 may be in any other form and number.

Fig. 5 is a schematic view of the handle assembly shown in fig. 1 with the first and second rotating parts 40 and 50 separated from each other. Referring to fig. 5, when the handle 20 is released, the second elastic member 70 is deformed again to separate the first rotating portion 40 and the second rotating portion 50, and the abutting portion 52 of the second rotating portion 50 is located away from the first rotating portion 40, i.e., separated position. The first and second rotation parts 40 and 50 are easily abutted and separated by the second elastic member 70.

The utility model provides a switching device leans on through the inside first rotating part 40 of its handle assembly and the support of second rotating part 50, when handle 20's rotation, the first rotating part 40 of second rotating part 50 drive rotates with drive square shaft 310, with second rotating part 50 follow with first rotating part 40 support by the state separation back, twist grip can not drive the rotation of first rotating part, the square shaft can rotate under the drive of the cabinet door turning handle 200 of regulator cubicle to with switching device separating brake or combined floodgate and do not receive handle assembly's influence.
