[0002] Hornwood combo refers to a comb made of hornwood, and the comb is formed by splicing hornwood pieces together. Buffalo horn has a natural luster and texture. This kind of comb usually has a natural texture and unique grain, suitable as a delicate personal care product. In order to facilitate people's use, the hornwood combo has a folding type.

[0003] When the existing products are used, due to the foldable feature, the comb can be divided into two forms: folded and unfolded. When the comb is in the unfolded state for combing the hair, there is no limit between the tooth frame and the handle, which causes the tooth frame to frequently shake due to the friction when combing the hair, making the connection between the tooth frame and the handle easy to break. In addition, when combing the hair, there is often moisture on the hair, and the moisture adheres to the teeth and the tooth frame, which easily corrodes the product, resulting in a reduced service life.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solution and advantages of the implementation of the utility model clearer, the technical solution in the implementation of the utility model will be clearly and completely described below in conjunction with the drawings in the implementation of the utility model. Obviously, the described implementation is a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0036] Reference Figure 1-8The utility model provides a technical solution: an anti-fracture corner wood combined comb, comprising a handle 1 and a tooth frame 2, the handle 1 and the tooth frame 2 are rotatably connected by a rotating shaft, teeth 3 are installed at the bottom of the tooth frame 2, the anti-fracture mechanism comprises a cavity 4, a straight groove 5, an arc groove 6 and a driving shaft 7, the cavity 4 is opened at the bottom of the handle 1, the straight groove 5 is opened at the front side of the tooth frame 2, the arc groove 6 is opened at the front and rear sides of the inner wall of the cavity 4, the driving shaft 7 is slidably installed in the straight groove 5, and the front and rear sides of the driving shaft 7 both penetrate into the arc groove 6, the water filtering mechanism is arranged in the cavity 4, the handle 1 is opened in a limiting groove 10, and the limiting groove 10 is rotatably installed in the inner wall of the cavity 4. A limiting shaft 11 is provided, the shape of the arc groove 6 is semicircular, the shape of the limiting groove 10 is an inclined straight groove 5-shaped, a positioning groove 12 is provided on the front side of the limiting groove 10, a positioning handle 13 is slidably installed inside the positioning groove 12, the rear side of the positioning handle 13 is rotatably connected to the front side of the limiting shaft 11, a guide groove 14 is provided on the front side of the positioning groove 12, a guide shaft 15 is slidably installed inside the guide groove 14, the rear side of the guide shaft 15 is fixedly connected to the front side of the positioning handle 13, the shape of the limiting shaft 11 and the shape of the driving shaft 7 are both cylindrical, the right side of the limiting shaft 11 penetrates into the interior of the arc groove 6, the top of the positioning handle 13 penetrates to the top of the grip 1, and the limiting shaft 11 and the driving shaft 7 are both cylindrical. The right side of the positioning handle 13 penetrates to the right side of the grip 1, and the right side of the positioning handle 13 is set to an arc shape. By setting an anti-fracture mechanism, the gear rack 2 in the retracted state is rotated clockwise with the rotating shaft as the center. Since the center of the arc groove 6 coincides with the rotating shaft, the driving shaft 7 slides simultaneously inside the straight groove 5 and the arc groove 6. When reaching the preset position, since the right side of the limiting shaft 11 penetrates into the inside of the arc groove 6, the driving shaft 7 squeezes the limiting shaft 11, so that the limiting shaft 11 moves toward the other end of the limiting groove 10 while rotating. Through the cooperation of the guide groove 14 and the guide shaft 15, the limiting shaft 11 drives the positioning handle 13 to move inside the positioning groove 12 until The driving shaft 7 passes through the obstruction of the limiting shaft 11 and reaches the top of the left side of the arc groove 6. At this time, due to gravity, the limiting shaft 11 drives the positioning handle 13 and the guide shaft 15 back to the original position. While the user holds the handle 1, he also squeezes the positioning handle 13, so that the positioning handle 13 cannot move inside the positioning groove 12, and indirectly limits the limiting shaft 11, so that the driving shaft 7 cannot move. On the contrary, moving the positioning handle 13 allows the limiting shaft 11 to move, and the limiting shaft 11 no longer blocks the driving shaft 7. The tooth frame 2 is rotated counterclockwise to return the comb to the retracted state, thereby solving the problem that the existing product is prone to breakage due to no limit at the connection.

[0037] It is worth noting that two of the limiting groove 10, the limiting shaft 11, the positioning groove 12, the positioning handle 13, the guide groove 14, the guide shaft 15, the first filter block 8 and the second filter block 9 are provided correspondingly.

[0038] Reference Figure 1-8The water filtering mechanism comprises a first filter block 8 and a second filter block 9. The first filter block 8 is fixedly mounted on the inner wall of the cavity 4, and the second filter block 9 is fixedly mounted on the inner wall of the cavity 4. The length of the second filter block 9 is shorter than that of the first filter block 8. The first filter block 8 and the second filter block 9 are both made of sponge rubber, which has good water absorption and elasticity. The lengths of the first filter block 8 and the second filter block 9 are respectively the same as the lengths of the rack 2 and the teeth 3. By setting the water filtering mechanism, when the rack 2 rotates counterclockwise back to the retracted state, since the gap between the two second filter blocks 9 is smaller than the gap between the two first filter blocks 8 and is adapted to the teeth 3, the teeth 3 pass through the first filter block 8 and enter the second filter block 9, and are squeezed by the second filter block 9. Similarly, when the rack 2 rotates to the preset position, it is squeezed by the first filter block 8. Since the first filter block 8 and the second filter block 9 are made of sponge rubber, the first filter block 8 and the second filter block 9 absorb the moisture on the rack 2 and the teeth 3, thereby avoiding the problem that the rack 2 and the teeth 3 are corroded by moisture for a long time and the service life is reduced.

[0039] Specifically, the working process or working principle of the anti-breakage corner wood spliced ​​comb is as follows: when in use, the tooth frame 2 in the folded state is rotated clockwise with the rotating shaft as the center. Since the center of the arc groove 6 coincides with the rotating shaft, the driving shaft 7 slides simultaneously inside the straight groove 5 and the arc groove 6. When reaching the preset position, the right side of the limiting shaft 11 penetrates into the interior of the arc groove 6, causing the driving shaft 7 to squeeze the limiting shaft 11, causing the limiting shaft 11 to move toward the other end of the limiting groove 10 while rotating. Through the cooperation of the guide groove 14 and the guide shaft 15, the limiting shaft 11 drives the positioning handle 13 to move inside the positioning groove 12 until the driving shaft 7 passes through the obstruction of the limiting shaft 11 and reaches the top of the left side of the arc groove 6. At this time, due to gravity, the limiting shaft 11 drives the positioning handle 13 and the guide shaft 15 back to their original positions, and the user holds the limiting shaft 11 in his hand. While turning hand 1, the positioning handle 13 is also squeezed, so that the positioning handle 13 cannot move inside the positioning groove 12, and the limiting shaft 11 is indirectly limited, so that the driving shaft 7 cannot move. On the contrary, the positioning handle 13 is moved to move the limiting shaft 11, and the limiting shaft 11 no longer blocks the driving shaft 7. The tooth rack 2 is rotated counterclockwise to return the comb to the retracted state. Since the gap between the two second filter blocks 9 is smaller than the gap between the two first filter blocks 8 and is adapted to the teeth 3, the teeth 3 pass through the first filter block 8 and enter the second filter block 9, and are squeezed by the second filter block 9. Similarly, when the tooth rack 2 is rotated to the preset position, it is squeezed by the first filter block 8. Since the first filter block 8 and the second filter block 9 are made of sponge rubber, the first filter block 8 and the second filter block 9 absorb the moisture on the tooth rack 2 and the teeth 3.
