Claims

[Scope of utility model registration request]

The upper unit and the lower unit are pivotally connected at their base ends, and the upper unit is urged to rotate upward, and the upper unit and the lower unit are locked at their distal ends by a lock consisting of a lock pawl and a lock receiver. In the upper and lower bisecting device configured to be able to be locked in the closed state by a means, the lock pawl and the lock receiver can be attached and detached by a shaft passing through the lock pawl in a direction perpendicular to the direction of rotation of the lock pawl. A structure for fixing the upper and lower halves during transportation, characterized by the fact that they are joined together.
