Claims

[Scope of utility model registration request]

an engagement groove that is made up of a cylindrical body provided with a locking pawl on one end and a column inserted into the cylinder so as to be relatively linearly movable from the one end, and that engages with the locking pawl in the column; are provided in the linear movement direction, and only forward movement into the cylindrical body is prevented by engagement of the locking pawl with the engagement groove, and this engagement is caused by operation of a lever. A telescoping column configured so that the column can reciprocate by being released.
