Description

Side-press red and blue automatic drawing pen

technical field

The invention relates to a side-press type red and blue automatic drawing pen.

Background technique

For decades, in clinical nursing work, wooden red and blue pencils have been used to draw temperature sheets, which are easy to break and wear, and repeated cutting is time-consuming and wasteful.

Utility model content

In view of the disadvantages that the existing wooden red and blue pencils used by nurses when drawing body temperature sheets by hand are easy to break lead, easy to wear, time-consuming to repeatedly cut and seriously wasteful, the utility model adopts the following technical solutions:

A side-pressing type red and blue automatic drawing pen, which is equipped with a lead core, a pen head, a pen holder, a clamping head, a fixed core protection tube and a core storage tube on the inside of both ends of the pen tube; the lead core is stuck by the clamping head after passing through the pen tip Then enter the pen holder, one end of the pen holder is fixedly connected to the chuck, and the other end of the pen holder is connected to the core tube; the fixed core tube is fixedly connected to the nib; A spring is arranged between the core protection tubes, and the core storage tube is provided with a slope; side buttons are also provided on the outside of the two ends of the pen tube, and the side buttons can move to the inside of the pen tube; the side buttons are connected to the core storage tube through the slope ; One of the lead cores is blue and the other is red.

The utility model improves the ordinary automatic pencil, adopts a special way of side pressing, double heads, and two-way lead cores respectively, and uses red and blue lead cores with a diameter of 0.7mm, which not only conforms to the habit of nurses using drawing pens, but also It is free from sharpening the pen and can ensure the drawing effect to the greatest extent, which saves time, labor and environmental protection, and is convenient for nurses to work.

Explanation of reference signs: 1 lead core; 2 pen head; 3 clamping head; 4 fixed core protection tube;

Detailed ways

The side-pressing type red and blue automatic drawing pen will be described in further detail below mainly in conjunction with the accompanying drawings and specific embodiments.

As shown in Fig. 1 and Fig. 2, a kind of side-press type red and blue automatic drawing pen of an embodiment: all be provided with lead core 1, nib 2, pen holder 7, clamping head 4, fixed on the inside of both ends of pen tube 9 Core protection tube 4 and core storage tube 6; lead core 1 passes through nib 2 and is stuck by chuck 4 and then enters pen holder 7, one end of pen holder 7 is fixedly connected to chuck 4, and the other end of pen holder 7 is connected to storage core tube 6; The fixed core protection tube 4 is fixedly connected to the nib 2; the core storage tube 6 is slidably connected to the fixed core protection tube 4, and a spring is arranged between the core storage tube 6 and the fixed core protection tube 4, and the core storage tube 6 is provided with a slope 8; Side buttons 5 are also provided on the outside of the two ends of the pen tube 9, and the side buttons 5 can move to the inside of the pen tube 9; the side buttons 5 are connected to the core storage tube 6 through the inclined plane 8; one of the lead cores 1 is blue color, and the other is red.

When the finger presses the side button 5 to the inside of the pen tube 9, it presses the slope 8 set by the core storage tube 6, forcing the core storage tube 6 to drive the pen holder 7 to move toward the nib 2, and the core storage tube 6 resists the fixed protection on one side. The force of the spring connected to the core tube 4 advances along the direction of the nib 2, and the movement of the penholder 7 to the direction of the nib 2 impels the clamping head 3 holding the lead 1 to open and send the lead 1 out. After the side button 5 is released, the power of the spring connecting the core storage tube 6 and the fixed core protection tube 4 impels the core storage tube 6 to drive the penholder 7 to return to its original position.

The utility model improves the ordinary automatic pencil, adopts a special way of side pressing, double heads, and two-way lead cores respectively, and uses red and blue lead cores with a diameter of 0.7mm, which not only conforms to the habit of nurses using drawing pens, but also It is free from sharpening the pen and can ensure the drawing effect to the greatest extent, which saves time, labor and environmental protection, and is convenient for nurses to work.
