The control unit 100 is installed on the upper portion of the frame unit 110 and the frame unit 110 having a predetermined height, and is connected to the power transmission unit 200 to provide the power to the control unit 120 and the frame unit. It is installed on the top of 110 and includes a protective cover 130 installed on the upper surface of the switch unit 400 to protect the switch unit 400 .

The frame part 110 has a predetermined height. The control assembly 120 is installed on the upper part of the frame unit 110. If the frame unit 110 is not installed, the control assembly 120 is disposed on the floor and there is a concern that it may easily break down due to vibration or external shock. . Therefore, as the frame unit 110 having a predetermined height is installed and the manipulation bundle 120 is installed on the upper portion, the manipulation bundle can be protected from vibration coming up from the floor or external impact. The predetermined height of the frame unit 110 is not limited.

The manipulation assembly 120 includes a key 121 providing power and a connecting shaft 122 that moves forward or backward by interlocking with the rotational force of the key 121 .

The key 121 is located on the top of the manipulation assembly 120 and provides power by manual manipulation. In the present invention, power is provided by manually rotating the key, but the present invention is not limited thereto, and any method capable of providing power by manipulating the key can be used.

If the fixing part 111 and the first link 212 are not pin-coupled in the process of the first link 212 transmitting the power obtained from the connection part 122 to the second link 215, the space between the first links That is, since the space between the connection part 122 and the second link 215 is empty, when the connection part 122 operates, the operation of the first link 212 does not proceed smoothly in response to this, so from the connection part 122 The obtained power is not accurately transmitted to the second link 215 and a loss of power occurs. Therefore, by pin coupling the first link 212 with the fixing part 111, the fixing part 111 acts as a lever for the first link 212 and moves in the process of moving the connecting part 122 forward or backward. The first link 212 is able to transmit the power obtained from the connection unit 122 to the second link 215 without loss of power.
