The two ends of some existing eyebrow pencils are respectively provided with an eyebrow pencil and an eyelash brush, such as application numbers 202021411661.0 disclosed in Chinese patent documents, application publication number 2021.06.25 and the name of the utility model, namely 'antibacterial and antistatic double-head eyebrow pencil'; however, the eyebrow pencil and the sponge head are less adopted in the product and the like, and the inner cover in the sponge head cover is poor in structural design, so that the stability is poor, and the assembly and the production are inconvenient.

Disclosure of Invention

In order to overcome the defects, the utility model aims to provide the degradable thermoplastic eyebrow pencil in the field, so that the technical problems that the existing similar eyebrow pencil products lack structural design of a sponge head and the production and assembly are inconvenient due to poor structural design of an outer cover and an inner cover at one end of the sponge head are solved. The purpose is realized by the following technical scheme.

The utility model provides an eyebrow pencil is moulded to degradable heat, this eyebrow pencil's body one end is equipped with the spiral, and the spiral is equipped with the nib, and the other end of body is equipped with the brush holder, and the brush holder is equipped with the brush, and the brush one end outside of body is equipped with the brush lid, and the nib one end outside of body is equipped with the cap, and the pearl in the body drives through the rotatory spiral one end that stretches out the body and reciprocates to the eyebrow refill that sets up in the ball tip refill groove is stretched out from the nib. The pen is characterized in that a pen refill groove of the bead is formed in a pen core at one end of a rod, an open elastic groove is formed in a notch of the pen core, the diameter of the pen core is larger than that of the rod, a thread section larger than the diameters of the rod and the core is arranged at the other end of the rod, the thread section of the bead is screwed into an internal thread in a spiral, a rib of the outer diameter of one end of the spiral is inserted into a rotation stopping ring fixed in a pen body, the other end of the spiral is fixed in a hole opening of the pen body in a buckling mode, the end portion of the spiral stretches out the pen body, a pen nozzle is fixed in a hole opening of the spiral stretching end in a buckling mode, and the core of the bead in the pen body is inserted into the pen nozzle. Above-mentioned structure is convenient for the pearl through the rotatory internal thread of assembling in the spiral of screw thread section, even in the automated production assembly between pearl and the spiral, and the spiral when rotatory use, drives the pearl in the spiral and reciprocates.

The ball pen is characterized in that one end of a rod part, extending from a threaded section of the ball, is provided with an end, the diameter of the end is larger than that of the rod part and smaller than that of the threaded section, an open side groove is formed in the end of the end, and the end of the ball abuts against an inner boss at the bottom in the pen body. Thereby when being convenient for the pearl to withdraw in the spiral, the bottom in the body of the pen is fixed a position and is fixed in, guarantees the further stability of pearl in spiral and body of the pen.

The pen is characterized in that a long waist-shaped through hole is symmetrically formed in the middle of a spiral in the pen body, the inner threads are arranged on the inner walls of the other two sides of the long waist-shaped through hole, and the inner threads are thread sections distributed at equal intervals. The structure is convenient for the stability of air tightness and the discharge of air pressure in the pen body.

The brush cover, the brush and the brush seat are omitted from the pen body. Namely, the partial structure of the eyebrow pencil can be used for independent eyebrow pencil products.

The pen body is reasonable in structural design, inconvenient to produce and assemble and good in sealing performance and stability, particularly the structural design of the bead is different from that of the existing similar product, and the length of the pen body and the length of the eyebrow pencil lead are improved through the structural design of the bead; it is suitable for being used as a double-head eyebrow pencil with a mascara brush and the structure improvement of the similar products.
