[0002] With the rapid development of the construction market, steel structures are increasingly used in construction projects, especially in the construction of factories, warehouses and other fields. During the installation of steel structure factories, self-tapping screws are used as fasteners, and are fixed to the steel structure frame through their nail heads. Socket wrenches may be used as auxiliary tools to tighten or remove self-tapping screws. During the tightening or removal process, a large amount of nail head paint will fall off, and the self-tapping screw heads will be worn and blackened. In order to improve the appearance and quality of steel structure factories, it is necessary to repaint the self-tapping screw heads on site to ensure that the color of the self-tapping screw heads on the wall panels is consistent with the color of the internal and external wall panels. The conventional repainting method is to use an oil painting brush to paint a little bit by hand, while the self-tapping screw heads include the top surface, the ring surface and six edges.

When in use, the touch-up paint head 2 is aligned and the nail head is inserted into the touch-up paint head 2, the sponge component 3 wraps the nail head and the outer wall of the nail head fits tightly with the inner wall of the sponge component 3, and at the same time, the valve 4 is opened, and the paint in the shell 1 flows into the touch-up paint head 2 and is absorbed by the sponge component 3, and then is smeared on the nail head that fits with the sponge component 3.

[0028] In the present invention, the valve 4 includes a hollow valve body 41, and an upper valve port 42 and a lower valve port 43 are respectively formed at both ends of the valve body 41. The valve 4 is connected to the outer shell 1 and the paint touch-up head 2 through the upper valve port 42 and the lower valve port 43 respectively; and, a valve core 44 is provided in a sliding sleeve inside the valve body 41, and the lower end of the valve core 44 extends into the paint touch-up head 2 through the lower valve port 43 and is connected to the sponge assembly 3, and a sealing plate 45 is provided on the valve core 44, and the outer diameter of the sealing plate 45 is larger than the inner diameter of the lower valve port 43; and, a spring 46 for pushing the sealing plate 45 to cover the lower valve port 43 is provided in the outer gap of the valve core 44, and the sealing plate 45 and the spring 46 are both located in the valve body 41, and the two ends of the spring 46 are respectively abutted or fixedly connected with the sealing plate 45 and one end of the valve body 41 close to the upper valve port 42. During the process of the nail head being inserted into the paint touch-up head 2, the top surface of the nail head is against the sponge component 3, pushing the sponge component 3 and the valve core 44 to move in the direction close to the outer shell 1, driving the sealing plate 45 to separate from the lower valve port 43, and the paint can flow into the paint touch-up head 2 from the outer shell 1, the upper valve port 42, the inside of the valve body 41, and the valve core 44 in sequence and be absorbed by the sponge component 3. At the same time, the spring 46 is compressed and applies a pressure reaction force to the sealing plate 45, the valve core 44, the sponge component 3, and the nail head in sequence, and the paint in the sponge component 3 is squeezed out and applied to the nail head, thereby achieving the effect of covering the nail head and pressing it to touch up the paint, and the paint is absorbed by the sponge component 3 in a non-squeezed state, which can effectively avoid problems such as paint overflow and sagging.

[0029] In the present invention, the valve core 44 includes a valve stem 441 and a valve tube 442, and the valve stem 441 and the valve tube 442 are respectively fixedly arranged on both sides of the blocking plate 45, wherein the valve stem 441 is loosely sleeved on the inner side of the spring 46 and the valve stem 441 is loosely matched with the upper valve port 42, so that the paint in the outer shell 1 can flow into the valve body 41 from the gap between the valve stem 441 and the upper valve port 42; the lower end of the valve tube 442 extends into the paint touch-up head 2 through the lower valve port 43 and is connected to the sponge assembly 3, and a paint inlet 443 is provided on the side wall of the upper end of the valve tube 442, and a first sealing ring 444 is sleeved on the outer side of one end of the valve tube 442 close to the blocking plate 45. When the valve 4 is closed, the two sides of the first sealing ring 444 are tightly fitted with the lower valve port 43 and the blocking plate 45, respectively, to further prevent the paint from entering the paint touch-up head 2 through the valve 4. When the valve core 44 moves toward the housing 1, the blocking plate 45 is separated from the lower valve port 43 and the upper end of the valve tube 442 and the paint inlet 443 enter the valve body 41, and the paint can flow into the paint touch-up head 2 from the housing 1, the upper valve port 42, the valve body 41, the paint inlet 443, and the valve tube 442 in sequence and be absorbed by the sponge component 3; the length of the paint inlet 443 is 8 mm and the width of the paint inlet 443 is 3 mm, so that during each press to touch up the paint, the amount of paint touch-up is exactly the same as the amount used on the surface of the nail head, and the paint touch-up is just consumed each time.

[0030] In the present invention, the sponge assembly 3 includes a sponge block 31 whose bottom surface can be attached to the top surface of the nail head, and a sponge ring 32 whose inner wall can be attached to the edge surface of the nail head, wherein the sponge block 31 is located directly below the valve tube 442 and the upper end of the sponge block 31 is plugged with the valve tube 442, and the sponge ring 32 is arranged in the paint touch-up head 2 and the sponge ring 32 is slidably sleeved on the outer side of the valve tube 442. The sponge block 31 is used to touch up the top surface of the nail head, and the sponge ring 32 is used to touch up the annular surface and six edge surfaces of the nail head, so that the nail head can be covered and pressed to touch up the outer wall of the nail head in turn, which is convenient and fast, saves labor, and can effectively avoid problems such as lack of paint, missed brushing, and paint dripping.

[0031] In the present invention, the valve 4, the valve core 44, the spring 46, the sponge block 31, the sponge ring 32, and the paint touch-up head 2 are all coaxial.

[0032] In the present invention, the sponge block 31 is a structure with a convex cross-section. The upper end of the sponge block 31 is plugged into the valve tube 442 and the outer diameter of the lower end of the sponge block 31 is equal to the outer diameter of the valve tube 442. Therefore, when repainting, the bottom surface of the sponge block 31 can fit the top surface of the nail head in all directions to avoid paint leakage.

[0033] In the present invention, the paint touch-up head 2 comprises a nail head inlet 21, a cavity wall 22, and a threaded opening 23 which are connected in sequence. The outer diameters of the nail head inlet 21, the cavity wall 22, and the threaded opening 23 are increased in sequence to form a three-stage variable diameter step structure. The sponge ring 32 is sleeved in the cavity wall 22, and the valve 4 is fixedly sleeved on the inner side of the threaded opening 23, and the threaded opening 23 is threadedly connected to the housing 1. The outer wall of the sponge ring 32 is bonded to the inner wall of the cavity wall 22 or the two are interference fit; the design of the three-stage variable diameter step structure can not only wrap the sponge ring 32, but also effectively prevent the sponge ring 32 and the sponge block 31 from directly contacting the steel structure wallboard to cause pollution; considering the thickness of the self-tapping nail head ring itself, the height of the nail head inlet 21 is designed to be 1mm.

[0034] In the present invention, the valve body 41 includes a valve cover and a trumpet-shaped valve shell, one end of the valve cover is fixedly connected to the threaded port 23 and the other end of the valve cover is threadedly connected or fixedly connected or interference fit with the valve shell, and the upper valve port 42 and the lower valve port 43 are respectively opened on the valve cover and the valve shell.

[0035] In the present invention, the inner diameter of the nail head inlet 21 is smaller than the outer diameter of the sponge ring 32 and the inner diameter of the nail head inlet 21 is larger than the inner diameter of the sponge ring 32. The diameter of the nail head inlet 21 is 1 mm larger than the diameter of the nail head ring surface. For example, when repainting a nail head with a nail head ring surface diameter of 11 mm, a nail head repainting tool with a nail head inlet 21 diameter of 12 mm is used for repainting, thereby preventing the sponge ring 32 from escaping from the repainting head 2 at will and partially exposing the bottom surface of the sponge ring 32, and the exposed part can just fit with the nail head ring surface and be repainted.

[0036] In the present invention, the shell 1 includes a shell body 11, one end of the shell body 11 is threadedly connected to the threaded port 23 and the other end of the shell body 11 is threadedly connected to a tail cover 12 to form a space for accommodating paint, and a liquid stirring bead 13 is placed in the shell body 11. Shaking the shell 1 can make the liquid stirring bead 13 roll and move and stir the paint, thereby extending the solidification time of the paint; both ends of the shell body 11 are sleeved with a second sealing ring 14, which can effectively prevent paint leakage. In the present invention, the shell 1 is a long pen-shaped structure, which is easy to carry and use.

[0037] The present invention further includes a cap 5, one end of which is a closed end and the other end of which is transitionally matched with the cavity wall 22, so as to cover the nail head inlet 21, thereby effectively preventing unused paint from leaking through the nail head inlet 21, and effectively extending the wetting time of the paint, thereby preventing the sponge component 3 from being scrapped due to paint drying.

[0038] When the present invention is in use, the nail head is aligned and inserted into the paint touch-up head 2 through the nail head inlet 21. During the process of the nail head entering the paint touch-up head 2, first, the top surface of the nail head abuts against the bottom surface of the sponge block 31, and the sponge block 31 and the valve core 44 are pushed in sequence and move synchronously toward the direction close to the shell 1 until the bottom surface of the nail head inlet 21 abuts against the wall. At this time, the blocking plate 45 is separated from the lower valve port 43 and the paint inlet 443 enters the valve body 41, and the paint can be sequentially drawn from the shell 1, the upper valve port 42, The valve body 41, the paint inlet 443, and the valve tube 442 flow into the touch-up paint head 2 and are absorbed by the sponge block 31 and the sponge ring 32, and the sponge block 31 is squeezed by the nail head top surface and the valve tube 442, and the sponge ring 32 is squeezed by the nail head ring surface and the valve body 41, so that the bottom surface of the sponge block 31 and the nail head top surface, the bottom surface of the sponge ring 32 and the nail head ring surface, and the inner wall of the sponge ring 32 and the nail head edge surface are closely fitted, and the paint in the sponge block 31 and the sponge ring 32 will be squeezed out and applied to the outer wall of the nail head. Therefore, the present invention is easy to use, can effectively save labor and improve the quality of touch-up paint.
