DETAILED DESCRIPTION

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a measuring instrument scale marking structure, comprising a fixing frame 2 mounted on a measuring tape and a marking frame 6 corresponding to the fixing frame 2, characterized in that a ruler strip 1 is slidably fitted in the marking frame 6, a correction pen 7 is mounted in the marking frame 6, a clamp 8 is elastically fitted in the marking frame 6, the clamp 8 corresponds to the correction pen 7, a telescopic rod 10 is fixed in the marking frame 6, a cutter head 16 is fixed at one end of the telescopic rod 10, and the cutter head 16 is located on the side of the correction pen 7 close to the measuring tape.

[0022] In this embodiment, the internal threads of the fixing frame 2 are matched with a plurality of screws 5 , and the fixing frame 2 is fixedly connected to the measuring tape via the screws 5 .

[0023] Specifically, the fixing frame 2 and the measuring tape can be fixed together by screws 5, so as to facilitate marking on the measuring tape 1 after pulling the measuring tape 1.

[0024] A card slot 3 is provided in the fixing frame 2 , a card block 4 is fixed on the marking frame 6 , the card block 4 corresponds to the card slot 3 , a slide rail 17 is fixed in the marking frame 6 , the slide rail 17 corresponds to the ruler 1 .

[0025] Specifically, when the ruler 1 is pulled longer and needs to be marked in the middle of the ruler 1, the marking frame 6 can be pulled upward to pull the card block 4 out of the card slot 3, thereby removing the marking frame 6. The marking frame 6 can then be moved to facilitate marking the middle of the pulled ruler 1.
