Description

A kind of automatic ball-pen

Technical field

The utility model relates to a kind of automatic ball-pen.

Background technology

At present, conventional automatic ball-pen is when needs are write, need the button pressing its top, thus the compressing shaft of a writing brush moves down, then utilize rotary buckle structure to carry out spacing to it, after writing, need again to press ceiling button, thus it is rotated again, by the pen core nib retraction shaft of a writing brush; Due to needs repeatedly by, in frequent use procedure, often forget and press ceiling button, especially in industries such as express deliveries, need frequent signature, often find to forget the situation of pressing the button, thus the nib of stretching out easily causes damage to it in carrier's walking process.

Summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, provides the automatic ball-pen that a kind of structure is simple, security performance is high.

The purpose of this utility model is achieved in that

A kind of automatic ball-pen, described automatic ball-pen includes the shaft of a writing brush, pen core is inserted with in the described shaft of a writing brush, the tube wall of the described shaft of a writing brush has one section to be set to flexible lasso, the endoporus of this flexible lasso is two taper holes be interconnected, and the aperture, upper end of taper hole is less than aperture, lower end, and the joint face of two taper holes is arranged to a ledge structure, described pen core and flexible lasso opposite position place are provided with fastener, and fastener is set to two pyramidal structures, and the pyramidal structure being positioned at top is in the taper hole being positioned at top, is between two taper holes in the pyramidal structure of below; Described pen core is set with a spring, the top of this spring is connected to the bottom of the pyramidal structure being positioned at below, and spring bottom is connected to the nib open place of the shaft of a writing brush.

Compared with prior art, the beneficial effects of the utility model are:

The utility model is when needs are write, press flexible lasso, thus extrude the wedge shape fastener of its inside, it is made to drive pen core to move downward, pen core head is pressed down nib, thus can write easily, unclamp flexible lasso after writing and pen core head can be made to retract in the shaft of a writing brush under the elastic force effect of spring, therefore its structure is simple, easy to use and with writing with high by, security performance.

Accompanying drawing explanation

Fig. 1 is the structural representation of a kind of automatic ball-pen of the utility model.

Wherein:

The shaft of a writing brush 1, flexible lasso 2, pen core 3, fastener 4, spring 5.

Detailed description of the invention

See Fig. 1, a kind of automatic ball-pen that the utility model relates to, described automatic ball-pen includes the shaft of a writing brush 1, pen core 3 is inserted with in the described shaft of a writing brush 1, the tube wall of the described shaft of a writing brush 1 has one section to be set to flexible lasso 2, the endoporus of this flexible lasso 2 is two taper holes be interconnected, and the aperture, upper end of taper hole is less than aperture, lower end, and the joint face of two taper holes is arranged to a ledge structure, described pen core 3 is provided with fastener 4 with flexible lasso 2 opposite position place, and fastener 4 is set to two pyramidal structures, and the pyramidal structure being positioned at top is in the taper hole being positioned at top, be between two taper holes in the pyramidal structure of below, described pen core 3 is set with a spring 5, the top of this spring 5 is connected to the bottom of the pyramidal structure being positioned at below, and spring bottom is connected to the nib open place of the shaft of a writing brush 1,

When needing to write, extrude flexible lasso 2 with hand, thus make fastener 4 move down pressuring spring 5 along the taper hole of flexible coil 2 inwall, and utilize the step at two taper hole joint face places to position fastener 4; Now the nib of pen core 3 stretches out the nib open of the shaft of a writing brush 1, can write, and after writing, unclamps finger, and now under the elastic force effect of spring 5, fastener 4 drives pen core 3 to move upward, and makes in the nib retraction shaft of a writing brush 1 of pen core 3;

In addition: it should be noted that above-mentioned detailed description of the invention is only a prioritization scheme of this patent, any change that those skilled in the art does according to above-mentioned design or improvement, all within the protection domain of this patent.
