At this time, when the pressing lever 140 is pressed as shown in the arrow 700 of FIG. 13 and moved downward (inward direction of the hinge unit), the pressing inclined surface 143 of the pressing lever 140 is each pin member 131 ) Simultaneously presses the inclined surface 133, and the pin member 131 slides in the inner direction of the cover 120 by this pressing force.

At this time, the fixing pin 132 is moved to the inside of the cover 120 as shown by the arrow 800 and is separated from the reinforcing bracket 26 and the insertion groove 25, so that the hinge unit 110 can be rotated. There will be.

Therefore, the user rotates the operation handle 100 through the operation of the pressure lever 140 to be stored in the handle receiving portions 11 and 12 of the board main body 10, or stand upright on the board main body 10 to be fixed. By doing so, it is possible to switch to the electric kickboard mode or the electric skateboard mode.

Here, the fixing pin 132 is rotated with the rotation of the hinge unit 110, and in this process, the position of the through hole formed in the reinforcing bracket 26 and the insertion groove 25 formed in the hinge coupling groove 20 When coincident with, it elastically protrudes in the outer direction of the cover 120 and is fitted into these through holes and insertion grooves 25.

On the other hand, the pressing lever 140 only needs to be pressed when the fixing pin 132 is retracted, and the front end of the fixing pin 132 is supported by contacting the reinforcing bracket 26 while the hinge unit 110 is rotating. When only the operation rod 150 is rotated, the operation handle 100 can be accommodated or fixed according to each mode.

Therefore, the user can easily switch to the electric kickboard mode and the electric skateboard mode through the operation of the pressure lever 140.
