Abstract
The utility model relates to a thumbtack. The thumbtack comprises a nail cap and a nail rod, wherein the top end of the nail rod is vertically and fixedly connected in the center of the lower surface of the nail cap; an arc groove is formed on the upper surface of the nail cap; a square groove is formed in the nail cap; and a lever mechanism is arranged in the square groove. When the thumbtack is used, the nail cap is pressed; the fingers are positioned in the arc groove so as to enable pressure to be focused; even if the thumbtack is hammered into a hard wood plate or a wall, the nail rod is easily bent; when the thumbtack which is hammered into the wood plate or the wall needs to be drawn out, the lower surface of the nail cap is separated from the wood plate or the wall by the lever mechanism; and the thumbtack is drawn out of the wood plate or the wall by the hands; and therefore, the thumbtack is very convenient to use.
Description
Technical field
The utility model relates to a kind of drawing pin, and the drawing pin that the time nail bar that is a kind of use the particularly is not easy bending and is convenient to choose belongs to the office appliance technical field.
Background technique
Drawing pin be people impart knowledge to students or daily life work in use very frequent instrument, it mainly is in order to be used for drawing, lightweight products such as calligraphy and painting are fixed on plank or the wall.During use, the pressure that the press...withes one's finger head of a nail will be followed closely bar and hammer in plank or the wall.In the time of in hammering into harder plank or wall, because the head of a nail of existing drawing pin is generally spherical cap-shaped structure, pressing force disperses, and causes following closely rod bending easily.When drawing pin hammers into need choose in plank or the wall time, can only just can choose through the hard thing perk of the sheet head of a nail, very expense.Nowadays occurred drawing pin on the market and pulled up device,, all need carry drawing pin at every turn when choosing and pull up device, very inconvenience though use its very labour-saving drawing pin of choosing.
The model utility content
The utility model purpose is the drawing pin that the nail bar is not easy bending and is convenient to choose when for the deficiency that overcomes existing technology a kind of the use being provided.
For achieving the above object, the technological scheme that the utility model adopts is: a kind of drawing pin, comprise the head of a nail and nail bar, and said nail masthead end and head of a nail lower surface central vertical are affixed, and the upper surface of the said head of a nail is provided with arc groove; Be provided with square groove in the said head of a nail; Be provided with leverage in the said square groove.
Preferably, be arranged with two square grooves in the said head of a nail.
Preferably, said leverage comprises running shaft, connecting rod, pulling block and jacking block; Said connecting rod is arranged in the square groove through running shaft; The two ends of said connecting rod are provided with pulling block and jacking block; The upper surface of said pulling block stretches out the upper surface of the head of a nail; The lower surface of said jacking block is equal with the lower surface of the head of a nail.
Preferably, said pulling block is provided with draw ring; Said draw ring is positioned at outside the head of a nail.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The drawing pin of the utility model because the upper surface of the head of a nail is provided with arc groove, during use, is pushed the head of a nail, and finger is in the arc groove, and pressing force is concentrated, even when hammering in harder plank or the wall, the nail bar is also crooked easily; Owing to be provided with square groove in the head of a nail, be provided with leverage in the square groove again, when drawing pin hammers into need choose in plank or the wall time, through leverage, lower surface top that can the head of a nail is extracted plank or wall with hand with drawing pin then from plank or wall, and is very convenient.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the structural representation of the drawing pin of the utility model;
Wherein: 1, the head of a nail; 2, nail bar; 3, arc groove; 4, square groove; 5, running shaft; 6, connecting rod; 7, pulling block; 8, jacking block; 9, draw ring.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The described a kind of drawing pin of the utility model shown in accompanying drawing 1 comprises the head of a nail 1 and nail bar 2, and said nail bar 2 tops and the head of a nail 1 lower surface central vertical are affixed, and the upper surface of the said head of a nail 1 is provided with arc groove 3; Symmetry is provided with two square grooves 4 in the said head of a nail 1; Be provided with leverage in said each square groove 4; Said leverage comprises running shaft 5, connecting rod 6, pulling block 7 and jacking block 8; Said connecting rod 6 is arranged in the square groove 4 through running shaft 5; The two ends of said connecting rod 6 are provided with pulling block 7 and jacking block 8; The upper surface of said pulling block 7 stretches out the upper surface of the head of a nail 1; The lower surface of said jacking block 8 is equal with the lower surface of the head of a nail 1; Said pulling block 7 is provided with draw ring 9; Said draw ring 9 is positioned at outside the head of a nail 1.
The utility model is pushed the head of a nail 1 with thumb in use, and thumb is in the arc groove 3, and pressing force is concentrated, even when hammering in harder plank or the wall, nail bar 2 is also crooked easily; When drawing pin hammers into need choose in plank or the wall time; Hand takes two draw rings 9 outwards to spur, and pulling block 7 outwards moves, and drives jacking block 8 through connecting rod 6 and inwardly moves; Jacking block 8 stretches out the lower surface of the head of a nail 1; Plank or wall are left in the lower surface top of the head of a nail 1, with hand drawing pin is extracted plank or wall then, very convenient.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
