Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] A center marking device for floor cutting includes a body 1.

[0029] In this implementation scheme: The existing device {Publication (Announcement) No.}: CN203542592U discloses an auxiliary marking device for a woodworking cutting saw. Regarding this existing auxiliary marking device for a woodworking cutting saw, this application makes further improvements, as detailed in the following disclosure. To solve the technical problems existing in this prior art, such as the background art disclosed above, "When processing existing flooring or wood, there is a need to cut the flooring or wood into two parts. However, the above-mentioned device cannot quickly and accurately mark the center position of the flooring or wood, and cannot mark the center line of the flooring or wood, which makes the cutting of the flooring or wood inconvenient and affects the cutting accuracy, requiring further improvement." In combination with usage, this problem is obviously a real and difficult problem to solve. Therefore, to solve this technical problem, a marking component 2 and a limiting component 3 are added to this application.

[0030] like Figure 1-4 As shown:

[0031] It also includes a marking assembly 2 installed on the main body 1; the marking assembly 2 includes a fixed rod 21 located at the center of the upper surface of the main body 1, clamping rods 22 located on both sides of the fixed rod 21, and a rotating rod 23 rotatably connected to both ends of the upper surface of the fixed rod 21 via a rotating shaft A. The lower surfaces of the rotating rod 23 are rotatably connected to both sides of the lower surface via a rotating shaft B and clamping rods 22. A fixed block 24 is fixedly connected at the center of the upper surface of the fixed rod 21. A connecting rod 25 is fixedly connected to one side of the upper surface of the fixed block 24. Both ends of the outer side wall of the connecting rod 25 are slidably connected to sliding members 26 with a U-shaped structure. A mounting block 27 is fixedly connected to the side of the sliding member 26 away from the fixed block 24. The mounting block 27 is provided with a receiving groove for accommodating a marking pen 28. The marking pen 28 is movably disposed in the receiving groove.

[0032] In this implementation scheme: When in use, the operator can use the rotating rod 23 to clamp the clamping rods 22 on both sides to hold the body 1 located in the middle, so that the fixing rod 21 is in the center position of the body 1. At this time, the center line can be marked by the marking pen 28 installed in the mounting block 27, and the marking pen 28 can be quickly drawn on the center line by sliding on the connecting rod 25 through the sliding member 26.

[0033] It should be noted that the marker pen 28 can be selected from marker pens or pencils depending on the material being cut, so as to leave marks on cut flooring or wood of different materials.

[0034] In an optional embodiment, the height of the clamping rod 22 is twice the height of the fixing rod 21, and the body 1 is located between the two clamping rods 22 and is in contact with the clamping rods 22.

[0035] In this embodiment, the clamping rod 22 is higher than the fixed rod 21, thus clamping the body 1 located in the middle from both sides.

[0036] In an optional embodiment, the two clamping rods 22 and the two rotating rods 23 are parallel to each other.

[0037] In this embodiment, the parallelogram formed by the two clamping rods 22 and the two rotating rods 23 can be used to position the fixed rod 21, which is located at the center of the two rotating rods 23, on the center line of the body 1.

[0038] In an optional embodiment, the position of the marker pen 28 and the center position of the fixing rod 21 are on the same axis.

[0039] In this embodiment: Since the position of the marker pen 28 is consistent with the center position of the fixing rod 21, the marker pen 28 can mark the center position of the body 1.

[0040] In an optional embodiment, a fixing plate 29 is fixedly connected to the inner side wall of the mounting block 27 away from the slider 26. A first nut 210 is fixedly connected to the fixing plate 29 through a first receiving hole. A first bolt 211 is threadedly connected to the inner side wall of the first nut 210. The first bolt 211 and the marker pen 28 are in contact connection.

[0041] In this embodiment: by rotating the first bolt 211, the first bolt 211 can be moved within the first nut 210 on the fixing plate 29, and the first bolt 211 can be made to contact the marking pen 28, thereby fixing the marking pen 28 and making it convenient to use it for marking.

[0042] In an optional embodiment, the first bolt 211 is fixedly connected to an anti-slip pad of elastic material at one end near the marker pen 28.

[0043] In this implementation plan: by using an elastic anti-slip pad, the friction between the first bolt 211 and the anti-slip pad is increased, while the marker pen 28 is also protected to avoid damage caused by squeezing.

[0044] Furthermore:

[0045] The floor cutting center marking device also includes a limiting component 3, which includes a second nut 31 fixedly connected to a second receiving hole opened on the upper surface of the slider 26 and a second bolt 32 threadedly connected to the inner side wall of the second nut 31. The second bolt 32 extends into the interior of the slider 26 and contacts the connecting rod 25.

[0046] In this embodiment: by rotating the second bolt 32 located inside the second nut 31, the second bolt 32 can be made to abut against the connecting rod 25, thereby limiting the sliding member 26 and making it stable when not in use.

[0047] The working principle and usage process of this utility model are as follows: The operator can use the rotating rod 23 to clamp the body 1 located in the middle by the clamping rods 22 on both sides, so that the fixing rod 21 is located in the center of the body 1. By rotating the first bolt 211, the first bolt 211 can be moved in the first nut 210 on the fixing plate 29, and the first bolt 211 can be made to abut against the marking pen 28, thereby fixing the marking pen 28 for easy marking. At this time, the sliding member 26 can slide on the connecting rod 25, so that the marking pen 28 can quickly draw a line at the center line to achieve marking. By rotating the second bolt 32 located in the second nut 31, the second bolt 32 can abut against the connecting rod 25, thereby limiting the sliding member 26.

[0048] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
