A scribing tool Technical Field

[0001] This utility model relates to the field of line marking technology, and specifically to a line marking device. Background Technology

[0002] In the complex scenarios of industrial manufacturing, performing on-site machining tasks on installed mechanical equipment is often a challenging task. In such operations, precise scribing is crucial. It not only guides subsequent machining but also ensures the correctness of parts assembly and the rationality of machining allowances, thereby verifying whether the geometry and dimensions of the machined parts match the design drawings, effectively improving machining accuracy and work efficiency.

[0003] Currently, marking operations mainly use tools such as marking needles, marking compasses, set squares, vernier calipers, and height vernier calipers. However, due to the variety of work conditions and the complexity of using common marking tools, traditional marking tools are sometimes unable to meet the marking requirements of installed equipment.

[0004] During the operation, some shortcomings of conventional marking tools gradually become apparent: in a confined workspace, the operator's line of sight and range of motion are severely restricted, and conventional marking tools require the cooperation of both hands to complete the task. However, in a confined workspace, it is impossible to perform the operation of marking with both hands. In order to overcome this technical problem, this utility model provides a marking device. Summary of the Invention

[0005] The purpose of this invention is to provide a marking device that allows for single-handed marking, thereby overcoming the problem of difficulty in marking lines with both hands in a confined workspace.

[0025] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0026] In the description of this invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0027] Please refer to Figure 1. This utility model provides a marking device, characterized in that it includes a base 1, a telescopic plate 2, and a clamping plate 6.

[0028] The base 1 is L-shaped and has a base slot 1a on its back side. The base slot 1a is vertically arranged. A telescopic plate 2 and a clamping plate 6 are slidably connected to the base slot 1a, allowing the telescopic plate 2 and the clamping plate 6 to move up and down along the base slot 1a. The base 1, the telescopic plate 2, and the clamping plate 6 are connected to form an "E"-shaped structure. The clamping plate 6 is located between the horizontal plane of the base 1 and the horizontal plane of the telescopic plate 2. In use, the gap between the clamping plate 6 and the horizontal plane of the base 1 or the horizontal plane of the telescopic plate 2 is used to clamp the reference surface. The reference surface can be the edge of the equipment, a protrusion, etc. By clamping the reference surface with the clamping plate 6 and pushing the scribing device, one-handed scribing can be performed, thus overcoming the inconvenience of scribing with both hands in a narrow space. Since the clamping plate 6 can slide up and down, it can clamp reference surfaces of different thicknesses.

[0029] In some embodiments, the base 1 has a slot 1b on its back side, and the base slot 1a is located on the front and back sides of the slot 1b and communicates with the slot 1b. The telescopic plate 2 is also L-shaped and is inserted into the slot 1b. This arrangement prevents the telescopic plate 2 from rotating and allows it to move only up and down.

[0030] The telescopic plate 2 has a side strip hole 2b and a bottom through hole 2c on its vertical surface. The bottom through hole 2c is located directly below the side strip hole 2b. The side strip hole 2b coincides with the base strip hole 1a. A fastening component 8 is provided on the bottom through hole 2c and the rear side of the clamping plate 6. The fastening component 8 passes through the base strip hole 1a. Here, the fastening component 8 on the bottom through hole 2c is used to fasten the position of the telescopic plate 2, and the fastening component 8 on the clamping plate 6 is used to fasten the position of the clamping plate 6.

The second state is that the pen fixing plate 3 is connected to the front end of the vertical bracket 7, as shown in Figure 3. In this state, it is suitable for drawing vertical lines.

[0033] More specifically, a horizontal strip-shaped hole 2a is provided on the horizontal surface of the telescopic plate 2, and the pen fixing plate 3 is connected to the horizontal strip-shaped hole 2a by a fastening component 8. Here, the position of the pen fixing plate 3 can be fastened by the fastening component 8, and the pen 5 is parallel to the horizontal strip-shaped hole 2a. In this state, it is suitable for drawing horizontal lines.

[0034] Two extension arms 7b are provided on the rear side of the vertical holder 7. The extension arms 7b pass through the clamping plate 6 and are connected by the fastening assembly 8. Here, the fastening assembly 8 is used to fasten the extended position of the vertical holder 7. The front side of the extension arm 7b is provided with a notch 7a. The pen fixing plate 3 is vertically arranged in the notch 7a and is limited and fixed by the fastening assembly 8. Preferably, as shown in Figure 4, the pen fixing plate 3 is fixed on the vertical holder 7 by two sets of fastening assemblies 8. In this state, it is suitable for vertical drawing.

[0035] The pen fixing plate 3 is provided with a pen sleeve 4 for inserting the pen 5. The pen sleeve 4 is a cylindrical structure and is provided with a clamping component for holding the pen 5, so that pens 5 of different thicknesses can be clamped and fixed.

[0036] Specifically, the clamping assembly includes a pressure plate 42 and a gasket 41. The gasket 41 is disposed on the pressure plate 42. The pressure plate 42 is located in the pen sleeve 4 and is connected to the pen sleeve 4 through a fastening assembly 8.

[0037] In some embodiments, the fastening assembly 8 includes a hexagonal screw 8b and a wing nut 8a, wherein the wing nut 8a is threadedly connected to the hexagonal screw 8b, and the component can be fastened by rotating the wing nut 8a during use.

[0038] The working principle of this utility model is as follows:

[0039] When drawing horizontal lines, the pen fixing plate 3 is connected to the front end of the telescopic plate 2 through the fastening component 8. The extension positions of the telescopic plate 2 and the clamping plate 6 are adjusted and tightened so that the reference surface can be clamped between the clamping plate 6 and the horizontal surface of the base 1 or the horizontal surface of the telescopic plate 2. The pen 5 is inserted into the pen sleeve 4 and tightened. In this way, the line drawing can be achieved by simply pushing the line drawing device.

[0040] When drawing vertical lines, the pen fixing plate 3 is connected to the front end of the vertical bracket 7 through the fastening component 8. The extension distance of the vertical bracket 7 and the height of the clamp 6 are adjusted. When drawing lines, the base 1 can be pressed against the reference surface as the reference for drawing lines.

[0041] Although the present invention has been described herein with reference to several illustrative embodiments, it should be understood that those skilled in the art can devise many other modifications and implementations that fall within the scope and spirit of the principles disclosed herein. More specifically, various modifications and improvements can be made to the components or layout of the subject matter arrangement within the scope of the disclosure, drawings, and claims.
