[0041] Example 1

[0042] In the manufacturing and processing of steel structures, it is often necessary to scribing angle steel. The existing manual scribing method is not only time-consuming and labor-intensive, but also has large scribing errors, high labor costs, and low overall efficiency, which cannot meet the increasingly stringent requirements of the steel structure processing industry for angle steel scribing.

[0043] In view of this, the present invention provides an angle steel marking device, comprising: a blade holder 100, a fixed bracket 200, and a fastening structure 300. The blade holder 100 is connected to the fixed bracket 200 via the fastening structure 300. The blade holder 100 includes a blade head 110 and a blade handle 120. The blade head 110 and the blade handle 120 are connected at an angle. The blade head 110 has a blade tip 111 for marking. The blade handle 120 is provided with a lead screw structure along the axial direction. The fixed bracket 200 includes a connecting part 210 and a fitting part 220. The connecting part 210 and the fitting part 220 are connected at an angle. The connecting part 210 is connected to the lead screw structure. The fitting part 220 is used to abut against the angle steel 600 to be marked.

[0044] Please see Figure 1 The cutting head 110 and the handle 120 are vertically connected as a single unit. The cutting tip 111 is located at the end of the cutting head 110 away from the handle 120, forming an angle with the cutting head 110. It is used to scribing lines on the angle steel 600 to be scribed. The handle 120 has a lead screw structure at a horizontal point away from the cutting head 110. The connection position with the connecting part 210 can be adjusted by sliding the lead screw structure to meet the design requirements. The connecting part 210 and the fitting part 220 of the fixed bracket 200 are also vertically connected as a single unit. The connecting part 210 and the lead screw structure are connected and positioned by a connector. After positioning, the tool holder 100 and the fixed bracket 200 are connected and fixed by the fastening structure 300. The fitting part 220 is always in close contact with one side of the angle steel 600 to be scribed during scribing.

[0045] Please see Figure 3 Before using the angle steel marking device, adjust the horizontal distance between the cutter head 110 and the contact part 220 according to the drawing requirements by adjusting the connection position of the connecting part 210 and the lead screw structure. After adjustment, connect and fix the cutter holder 100 to the fixed bracket 200 through the fastening structure 300. When marking, use one hand to press the contact part 220 against the angle steel 600 to be marked, and use the other hand to press the handle 120 above the cutter head 110. At the same time, slide the handle 120 horizontally and evenly along the angle steel 600 to be marked inwards onto the paper, so that the cutter tip 111 marks a clear straight line on the surface of the angle steel 600.

[0046] The angle steel marking device has a simple structure and is easy to use. It can efficiently and quickly complete the marking of angle steel, solving the problems of large errors, long time, high cost and low efficiency of manual marking, thus effectively meeting the requirements of the steel structure processing industry for angle steel marking.

[0047] In an optional embodiment, the tool holder 120 includes an extension section 121 and a lead screw section 122. The lead screw structure is disposed on the lead screw section 122. The extension section 121 is provided with a plurality of first connection holes for connecting with the fastening structure 300. The plurality of first connection holes are spaced apart along the axial direction of the extension section 121.

[0048] Please see Figure 5 The total length of the tool holder 120 is 260mm, of which the protruding section 121 is 50mm long and the lead screw section 122 is 210mm long. The entire length of the lead screw section 122 is designed as a lead screw structure. The connection position with the bottom connecting part 210 can be adjusted by sliding the lead screw section 122 left and right, thus adjusting the horizontal distance between the tool head 110 and the mating part 220. Multiple first connecting holes (not shown in the figure) are evenly spaced along the length of the top of the protruding section 121. After adjusting the connection position between the lead screw section 122 and the connecting part 210, the fastening structure 300 can be inserted into the corresponding first connecting hole to connect and fix the tool holder 100 to the fixed bracket 200.

[0049] Furthermore, the end of the connecting portion 210 near the fitting portion 220 is provided with a second connecting hole for connecting with the fastening structure 300.

[0050] Since the fastening structure 300 is always connected to the end of the connecting part 210 near the fitting part 220, only one set of second connecting holes needs to be provided at the end of the connecting part 210 near the fitting part 220. By setting the fastening structure 300, one set of second connecting holes and multiple first connecting holes, a stable connection between the tool holder 100 and the fixed bracket 200 can be achieved, effectively ensuring the stability of the tool holder 100 during scribing.

[0051] In an optional embodiment, the fastening structure 300 includes a first fixing clip 310, which includes a first fixing part 311 and a second fixing part 312 connected to both sides of the first fixing part 311. The first fixing part 311 is connected to the protruding section 121, and the second fixing part 312 is connected to the connecting part 210.

[0052] Please see Figure 3 and Figure 6The first fixing part 311 is configured as an arc-shaped structure, with the maximum height of the arc exceeding the thickness of the tool holder 120. The first fixing part 311 is connected and fixed to the protruding section 121. A second fixing part 312 is connected to each side of the first fixing part 311. The second fixing parts 312 are horizontally positioned, and both second fixing parts 312 are connected and fixed to the connecting part 210. The first fixing part 311 and the two second fixing parts 312 are fixedly connected to form an integral structure, thereby achieving the connection and fixation between the tool holder 100 and the fixed support 200.

[0053] In an optional embodiment, the first fixing part 311 is provided with a first fastening hole 313, the second fixing part 312 is provided with a second fastening hole 314, and the fastening structure 300 further includes a first fastener 330 and a second fastener. The first fastener 330 passes through the first fastening hole 313 and is fixed to the first connecting hole, and the second fastener passes through the second fastening hole 314 and is fixed to the second connecting hole.

[0054] Please continue reading Figure 6 The first fixing part 311 has a first fastening hole 313 at the center of its arc, and the second fixing part 312 has a second fastening hole 314 near its center. The first fastener 330 passes through the first fastening hole 313 and is inserted into the corresponding first connecting hole, and the second fastener passes through the second fastening hole 314 and is inserted into the corresponding second connecting hole, thereby connecting and fixing the tool holder 100 and the fixing bracket 200 through the first fixing clamp 310.

[0055] Furthermore, the fastening structure 300 also includes a second fixing clip 320, which is spaced apart from the first fixing clip 310 on the tool holder 120.

[0056] Please see Figure 2 Furthermore, a second fixing clip 320 can be provided at the end of the connecting part 210 away from the fitting part 220. The structure and related hole positions of the second fixing clip 320 are exactly the same as those of the first fixing clip 310. By fixing the first fixing clip 310 and the second fixing clip 320 together, the connection between the tool holder 100 and the fixed bracket 200 can be made more stable, thereby improving the stability of the tool holder 100 during scribing.

[0057] In an optional embodiment, the connecting part 210 is provided with a slot 211, and the adjusting nut 400 passes through the lead screw structure and the slot 211 to position the lead screw section 122 and the connecting part 210.

[0058] Please see Figure 4A slot 211 is provided at the middle position of the connecting part 210. The adjusting nut 400 passes through the hole on the lead screw structure and is inserted into the slot 211, so that the lead screw section 122 and the connecting part 210 are initially positioned. When it is necessary to adjust the horizontal distance between the cutter head 110 and the mating part 220, the adjusting nut 400 can be removed, the cutter handle 120 can be slid horizontally, and after adjustment, the adjusting nut 400 can be installed and reset.

[0059] In an optional embodiment, a guide structure is provided between the connecting part 210 and the tool holder 120.

[0060] The guide structure can guide and limit the tool holder 120 when it slides in the horizontal direction, so that the tool holder 120 always slides in the left and right direction.

[0061] Specifically, the guide structure includes a guide tube 500, which has a cavity inside, and the tool holder 120 can slide axially within the cavity.

[0062] Please see Figure 1 The guide tube 500 is a hollow cylinder with a diameter larger than that of the tool holder 120. The tool holder 120 can slide left and right in the horizontal direction within the cavity of the guide tube 500, which facilitates the adjustment of the connection position between the connecting part 210 and the lead screw structure.

[0063] In an optional embodiment, the angle steel marking device further includes a drive mechanism, which is connected to the tool holder 120 in a transmission manner.

[0064] When a drive mechanism is provided, it can drive the tool holder 120 to slide horizontally and at a uniform speed along the angle steel 600 to be scribed inwards onto the paper, achieving semi-automatic scribing. The drive mechanism can be a cylinder or motor, commonly used in the mechanical field. Alternatively, a drive mechanism can be omitted, and the tool holder 120 can be slid manually.

[0065] The method of using the angle steel marking device in this embodiment is as follows:

[0066] First, adjust the horizontal distance between the cutter head 110 and the mating part 220 according to the drawings or design requirements. Slide the cutter handle 120 horizontally until it is in place. Then, pass the adjusting nut 400 through the hole on the lead screw structure and insert it into the slot 211 to initially position the lead screw section 122 and the connecting part 210. Then, connect and fix the cutter holder 100 to the fixed bracket 200 using the first fixing clamp 310 and the second fixing clamp 320. When scribing, use one hand to press the mating part 220 against one side of the angle steel 600 to be scribed, and use the other hand to gently press the cutter handle 120 above the cutter head 110. At the same time, slide the cutter handle 120 horizontally and at a uniform speed along the angle steel 600 to be scribed inwards onto the paper so that the cutter tip 111 scribes a clear straight line on the surface of the angle steel 600.
