Claims

[Scope of utility model registration request]

(1) Harmful to the outer wall in the length direction! A short cylindrical expanded-diameter nut having a groove and a female thread inside is slidably press-fitted into a large-diameter rod, and is screwed onto the expanded-diameter nut to connect the expanded-diameter nut to the large-diameter rod. A telescopic rod that can be assembled and disassembled, and is comprised of a small-diameter rod that can be inserted into the large-diameter rod, and has a locking bolt with a male screw attached to one end to fix the rod at any desired location.

(2) The telescopic rod according to claim 1, which is a utility model registration, characterized in that the large-diameter rod is provided with a striped protrusion that fits into the groove of the expanded-diameter nut in the length direction of the inner wall of the large-diameter rod.

(3) The telescopic rod according to claim 2, which is a registered utility model, characterized in that a relatively deep knurling is provided in the length direction of the outer circumferential wall of the expanded diameter nut.

(4) Utility model registration claim No. 1, characterized in that it consists of a large diameter rod to which two expanding diameter nuts are press-fitted, and two small diameter rods to which a locking bolt is attached to one end. The telescopic rod according to item 1, item 2, or item 3.

(5) A utility model characterized by using an expanding diameter nut with a taper toward the center near the inner and outer ends, and a locking bolt with a tapered portion near the tip and base that presses into contact with the taper. A telescopic rod according to registered claims 1, 2, or 4.
