It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0039] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.

[0041] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0042] At present, when marking on a curved skin surface, dot marks are usually made at the positions where marking is required, and then these points are connected one by one with a ruler to form an operating reference line or a punching position. This marking method is not only low in precision and efficiency, but also has high difficulty and poor stability for marking complex curved surfaces.

[0043] In order to solve the above problems, combined Figure 1-Figure 4 As shown, this embodiment provides an auxiliary marking device, which includes a rolling device 1, a measuring device 2 and a marking device 3. Two rolling devices 1 are provided, and the two rolling devices 1 are arranged at intervals. The rolling devices 1 move along a first direction (the X direction in the same figure), and one of the rolling devices 1 is provided with a limiter that limits the movement of the rolling device 1 along a second direction (the Y direction in the same figure), and the second direction is perpendicular to the first direction. The measuring device 2 is connected between the two rolling devices 1, and the measuring device 2 is used to display the marking size. The marking device 3 is slidably arranged on the measuring device 2 and marks the reference line or the punching position on the surface of the skin.

[0044] It can be understood that by wiping the area to be marked clean, and then placing the auxiliary marking device on the surface of the skin, so that the limiter always abuts against the side of the skin, after determining the marking distance, the marking device 3 is adjusted to the target size position in conjunction with the value displayed by the measuring device 2, and the rolling device 1 is pushed to slide along the first direction, that is, the side of the skin, so as to mark the reference line or the punching position. The measuring device 2 can intuitively display the value, has good stability, high reading accuracy, and reduces the error of manual reading. By rolling the rolling device 1 on the curved surface and cooperating with the marking device 3, continuous lines can be drawn on complex curved surfaces, without the need to connect two points one by one in a line in the traditional way, and the marking efficiency is better. .

[0045] Specifically, Figure 1 and Figure 2 As shown, the rolling device 1 of this embodiment includes a base 11 and a caster 14. The upper end surface of the base 11 is penetrated with a plurality of screw holes (not shown in the figure), and the lower end surface of the base 11 is provided with a fixing plate 12, the upper end surface of the fixing plate 12 is in contact with the base 11, and is connected to the base 11 by connecting screws (not shown in the figure), so that the fixing plate 12 is detachably mounted on the base 11, and the caster 14 can be replaced or removed by screwing and installing the connecting screws, and the structure is simple.

[0046] Furthermore, both ends of the fixing plate 12 are bent in a direction away from the base 11 to form mounting sections parallel to each other, the caster 14 is located between the two mounting sections, the rotating shaft 13 passes through the two mounting sections and the caster 14, the caster 14 is coaxially arranged with the rotating shaft 13, and both ends of the rotating shaft 13 are threadedly connected with nuts (not marked in the figure) that are tightly pressed against the outside of the mounting sections, so that the caster 14 is rotatably connected to the fixing plate 12, and the circumferential side of the caster 14 is in contact with the surface of the skin, and the auxiliary marking device is rolled on the surface of the skin through the rotation of the caster 14.

[0047] In this embodiment, two casters 14 are provided on the base 11, each caster 14 is provided corresponding to a fixing plate 12, and the axial direction of the casters 14 is perpendicular to the first direction. In other embodiments, the number of casters 14 can be one, three or even four, and this embodiment does not specifically limit the number. Of course, two casters 14 can also be provided on one fixing plate 12, and this embodiment does not specifically limit the number of fixing plates 12.

[0048] In order to facilitate the operator to move the rolling device 1, as Figure 1As shown, a handle 15 is provided on the base 11, and the handle 15 is generally "L"-shaped. One end of the handle 15 is threadedly connected to the screw hole of the base 11. The operator holds the handles 15 on the two bases 11 with both hands respectively to stably push the casters 14 to roll, so that the marking process of the marking device 3 is more stable, the mechanical structure is simple, the service life is long, and the failure rate is low.

[0049] Furthermore, if Figure 2 As shown, the limiting member includes a limiting plate 4, which is arranged on one side of the base 11, that is, the limiting plate 4 is located on the side away from the measuring device 2, and the length of the limiting plate 4 is greater than the sum of the diameter of the caster 14 and the thickness of the base 11. When the caster 14 is placed on the surface of the skin, the limiting plate 4 is movably abutted against the side of the skin. The limiting plate 4 abuts against the side of the skin to play the role of initial positioning, which is conducive to the subsequent marking operation.

[0050] Specifically, Figure 3 and Figure 4 As shown, the measuring device 2 of this embodiment includes a fixed grid scale 21, a sliding frame 22 and a moving grid digital display 23. The two ends of the fixed grid scale 21 are respectively connected to the two opposite side walls of the two bases 11. The fixed grid scale 21 is used as a connecting piece of the two bases 11 on the one hand, and as a scale for marking on the other hand. The surface of the fixed grid scale 21 is provided with a scale. The sliding frame 22 is slidably sleeved on the fixed grid scale 21, and the moving grid digital display 23 is connected to the sliding frame 22 to display the corresponding marking size of the sliding frame 22 on the fixed grid scale 21. The operator can accurately read the value of the sliding frame 22 on the fixed grid scale 21 through the moving grid digital display 23, and the reading is intuitive.

[0051] In order to facilitate the installation and removal of the fixed grid scale 21 and the base 11, the fixed grid scale 21 of different lengths can be matched. Figure 4 As shown, the two ends of the fixed grid scale 21 are respectively provided with connecting parts 211, and the side of the base 11 is provided with connecting holes 111 for the connecting parts 211 to be inserted, and the base 11 and the connecting parts 211 are connected by fixing screws 24. Preferably, the measuring range of the fixed grid scale 21 of this embodiment is 0mm-600mm. In other embodiments, the measuring range of the fixed grid scale 21 can be set or replaced with fixed grid scales 21 of different specifications according to actual conditions, and the applicability is strong. In addition, the numerical starting end of the fixed grid scale 21 is on the side with the limit plate 4, which is convenient for reading.

[0052] It should be noted that the reading of the corresponding value on the fixed grid scale 21 by the moving grid digital display 23 is a prior art, so this embodiment will not be further described in detail.

[0053] Specifically, Figure 3 and Figure 4As shown, the marking device 3 of this embodiment includes a bracket 31, a marking pen 33 and a fastener. The bracket 31 is extended and arranged on the sliding frame 22. The bracket 31 is arranged in an "L" shape. When the sliding frame 22 is slid and displayed, and the inner side of the L shape of the bracket 31 abuts against the side of the base 11, the moving grid digital display 23 is located at the starting end of the fixed grid scale 21, which is convenient for adjusting the moving grid digital display 23 to return to its original position. A through hole 311 is opened in the vertical direction at one end of the bracket 31 away from the sliding frame 22, and the marking pen 33 is inserted into the through hole 311. The fastener is used to lock the marking pen 33 on the bracket 31. Preferably, the marking pen 33 is an oil pen.

[0054] More specifically, if Figure 4 As shown, the fastener includes a fastening screw 32 , and a threaded hole 312 communicating with the through hole 311 is formed on the side of the bracket 31 . The fastening screw 32 is threadedly connected in the threaded hole 312 and the end thereof abuts against the peripheral side of the marking pen 33 .

[0055] Now combined Figure 1-Figure 4 The marking process of the auxiliary marking device is further described in detail:

[0056] First, wipe the pre-marked area clean;

[0057] Then, the auxiliary scribing device is placed on the surface of the skin, and the limiting plate 4 on the base 11 of the rolling device 1 on the left side is close to the side edge of the skin;

[0058] Secondly, insert the marking pen 33 into the through hole 311 and adjust it to a suitable height, and screw the fastening screw 32 until one end of the fastening screw 32 is pressed against the marking pen 33 in the through hole 311;

[0059] Furthermore, the marking distance is determined, and the sliding frame 22 is moved so that the value on the moving grid digital display 23 reaches the target size position;

[0060] Finally, the handle 15 is held to push the caster 14 to perform the marking operation.

[0061] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the scope of protection of the present invention. It is not necessary and impossible to list all implementation methods here.
