Abstract
The utility model discloses a chalk sleeve. The inside diameter of a circular hole shaped outer sleeve (1) is greater than the outside diameter of a cylindrical inner sleeve (4); a shell of the circular hole shaped outer sleeve (1) is provided with an elongated slot (2) in the horizontal direction, the shell in the vertical direction outside two sides of the elongated slot (2) is provided with a plurality of small holes (3) at intervals, and each pair of small holes (3) and the elongated slot (2) form a cross hole; and one end of the inner sleeve (4) is provided with a circular hole (5), a rod (6) is arranged on the upper part of the other end of the inner sleeve (4), a lug (7) is arranged above the head of the rod (6), a vertical rod (8) is arranged on each of two sides of the head of the rod (6), the rod (6) is matched with the elongated slot (2), the rod (6) is narrower than the elongated slot (2), and the connecting line between the two vertical rods (8) is longer than the connecting line of any one pair of small holes (3). The rod (6) generally has elasticity. Through the chalk sleeve, a chalk is convenient to use; and the chalk sleeve is material-saving and environment-friendly.
Description
(1) technical field
The invention relates to a kind of chalk sleeve.
(2) background technology
In daily productive life, chalk is relatively commonly used, but chalk uses very inconvenient sometimes or cannot fully utilize with to the end the time.
(3) summary of the invention
The technical problem that the invention will solve is: provide a kind of and use chalk easily and the chalk sleeve that chalk can be fully utilized with to the end the time.
The technical scheme of the invention is: chalk sleeve is characterized in that comprise the circular hole overcoat and the interior cover of column type that match, the internal diameter of circular hole overcoat is greater than the external diameter that overlaps in the column type; Have elongated slot on the shell horizontal direction of circular hole overcoat, have a plurality of apertures on elongated slot the two limit outside on the shell of vertical direction at interval, the every pair of aperture and elongated slot composition cross bore; One of interior cover has round hole; Top, other end is pole; The above-head of pole has a projection, and respectively there is individual vertical rod on head two limits of pole, and pole and elongated slot match; The width of pole is less than the width of elongated slot, and the wire length between two the vertical rod is greater than the wire length of any a pair of aperture.General pole is resilient pole.
Because the width of pole is less than the width of elongated slot; Wire length between two the vertical rod is greater than the wire length of any a pair of aperture; Interior of being with round hole is put into the circular hole overcoat, and projection is pinned the back put into one of them cross bore top along elongated slot, chalk is put into round hole and can firmly, convenient be used; Can projection be pressed in the cross bore of diverse location, to regulate the position or the length of chalk.
The invention make to use chalk easily and make chalk also can make full use of economical with materials, environmental protection with to the end the time.

Accompanying drawing 1 is the blast structural representation of the invention;
Accompanying drawing 2 is the right TV structure sketch map of the invention.
(5) specific embodiment
Embodiment: chalk sleeve is characterized in that comprise the circular hole overcoat 1 and the interior cover 4 of column type that match, the internal diameter of circular hole overcoat 1 is greater than the external diameter of cover 4 in the column type; Have an elongated slot 2 on the shell horizontal direction of circular hole overcoat 1, have a plurality of apertures 3 outside elongated slot 2 two limits on the shell of vertical direction at interval, every pair of aperture 3 is formed cross bore with elongated slot 2; One of interior cover 4 has round hole 5; Top, other end is pole 6; The above-head of pole 6 has a projection 7, and respectively there is individual vertical rod 8 on head two limits of pole 6, and pole 6 matches with elongated slot 2; The width of pole 6 is less than the width of elongated slot 2, and the wire length between two the vertical rod 8 is greater than the wire length of any a pair of aperture 3.General pole 6 is resilient pole.
Because the width of pole 6 is less than the width of elongated slot 2; Wire length between two the vertical rod 8 is greater than the wire length of any a pair of aperture 3; Have one of round hole 5 to put into circular hole overcoat 1 in interior cover 4, and projection 7 is pinned the back put into one of them cross bore top along elongated slot 2, chalk is put into round hole 5 and can firmly, convenient be used; Can projection 7 be pressed in the cross bore of diverse location, to regulate the position or the length of chalk.
The invention make to use chalk easily and make chalk also can make full use of economical with materials, environmental protection with to the end the time.
Claims (2)
1. a chalk sleeve is characterized in that, comprises the circular hole overcoat (1) and the interior cover of column type (4) that match, and the internal diameter of circular hole overcoat (1) is greater than the external diameter of cover (4) in the column type; Have an elongated slot (2) on the shell horizontal direction of circular hole overcoat (1), have a plurality of apertures (3) outside elongated slot (2) two limits on the shell of vertical direction at interval, every pair of aperture (3) and elongated slot (2) are formed cross bore; One of interior cover (4) has round hole (5); Top, other end is pole (6); The above-head of pole (6) has a projection (7), and respectively there is individual vertical rod (8) on head two limits of pole (6), and pole (6) and elongated slot (2) match; The width of pole (6) is less than the width of elongated slot (2), and the wire length between two the vertical rod (8) is greater than the wire length of any a pair of aperture (3).
2. a kind of chalk sleeve according to claim 1 is characterized in that, described pole (6) is resilient pole.
