a handle lower region disposed towards an end of the handle upper region and such that a second surface of the handle lower region faces a first surface of the handle upper region;
a shaft member configured to penetrate the handle upper region through a first portion of the first surface and the handle lower region through a second portion of the second surface of the handle lower region; and,
a support member coupled to a lower surface of a lower end of the handle upper region,
wherein a screw thread region is provided on an outer surface of the shaft member,
wherein the screw thread region is capable of being screw-coupled to one or more of the handle upper region or the handle lower region at one or more of the first portion or the second portion,
