[0020] The present invention will be further described below with reference to the embodiments.

[0021] The following embodiments are used to illustrate the present invention, but should not be used to limit the scope of protection of the present invention. The conditions in the embodiments can be further adjusted according to specific conditions, and simple improvements to the method of the present invention under the premise of the concept of the present invention are all within the scope of protection claimed by the present invention.

[0022] Please see Figure 1-4 This utility model provides a marking tape measure, including a tape measure body 1. A connecting frame 2 is provided on the outside of the tape measure body 1 at the hook winding end. Connecting grooves 101 are provided on both sides of the tape measure body 1. The top of the connecting frame 2 is provided on both sides with mating plates 201 that are adapted to the connecting grooves 101. Each of the two mating plates 201 has a limiting protrusion 202 on its opposite surface. Each of the connecting grooves 101 has a limiting groove 102 that is adapted to the limiting protrusion 202 on the side facing the mating plate 201. When the two mating plates 201 on the top of the connecting frame 2 are aligned with the connecting grooves 101 on both sides of the tape measure body 1, they are pushed vertically in the direction of the groove opening. During the insertion process, the limiting protrusions 202 on the surface of the mating plate 201 are squeezed by the inner wall of the connecting groove 101 and undergo slight deformation.

[0023] When the docking plate 201 is fully inserted, the limiting protrusion 202 reaches the position of the limiting groove 102, elastically resets and is locked into the groove, forming a mechanical lock. At this time, the connecting frame 2 and the tape measure body 1 form a stable connection. The outline of the limiting groove 102 is completely fitted with the limiting protrusion 202, preventing the connecting frame 2 from loosening along the length direction or vertical direction of the tape measure.

[0024] The elastic engagement mechanism between the limiting protrusion 202 and the limiting groove 102 enables the "plug-and-play" of the connecting bracket 2, allowing users to complete the installation or replacement without tools such as screwdrivers, significantly improving ease of use. Both sides of the docking plate 201 are equipped with limiting protrusions 202, which form a double-point locking with the limiting groove 102 of the measuring tape body 1, effectively resisting the vibration caused by the stretching and collision of the measuring tape during use, and preventing the connecting bracket 2 from falling off or shifting.

[0025] In this embodiment, a sliding plate 204 is slidably connected inside the connecting frame 2, and a connecting plate 3 is fixedly connected to the bottom of the sliding plate 204. A placement groove 301 is provided on one side of the connecting plate 3, and a marker pen is placed inside the placement groove 301. The distance between the tip of the marker pen and the retractable part of the ruler hook is two centimeters. A sliding groove 203 is provided inside the connecting frame 2, and the sliding plate 204 is slidably connected inside the sliding groove 203. A pull rod 205 is fixedly connected to one side of the sliding plate 204. One end of the pull rod 205 passes through and extends to the outside of the connecting frame 2, and a pull ring 207 is fixedly connected to the end of the pull rod 205. A spring 206 is fixedly connected between one side of the sliding plate 204 and one side of the inner cavity of the sliding groove 203, and the spring 206 is sleeved on the outside of the pull rod 205. The measuring tape body 1 has a placement groove 301 located on one side of the hook. The translation direction of the placement groove 301 is perpendicular to the stretching direction of the hook. A push-in port 304 is provided on one side of the placement groove 301. The width of the push-in port 304 is smaller than the diameter of the placement groove 301. Elliptical deformation cavities 305 are provided on the inner walls of both sides of the push-in port 304. A rubber ring 302 with the same shape as the placement groove 301 is provided inside the placement groove 301. Multiple fixing protrusions 303 are provided on the contact surface between the rubber ring 302 and the marker pen. Connecting rods are fixedly connected to the top of the connecting plate 3 on both sides of the placement groove 301. A "C"-shaped limiting plate 306 is provided on the top of the two connecting rods. The opening direction of the limiting plate 306 is opposite to the orientation of the push-in port 304.

[0026] When marking is required after measurement, the user holds the main body 1 of the measuring tape with one hand and pulls the pull ring 207 with their thumb or forefinger. The pulling force is transmitted to the sliding plate 204 through the pull rod 205, overcoming the elastic force of the spring 206, and driving the sliding plate 204 to move horizontally along the slide groove 203 towards the outside of the connecting frame 2. The sliding plate 204 drives the connecting plate 3 to move synchronously, so that the marking pen in the placement groove 301 extends out of the connecting frame 2, with the pen tip exposed on the outside of the hook retraction point. Since the direction of translation of the placement groove 301 is perpendicular to the direction of hook extension, the user can directly push the marking pen horizontally to the target scale line without rotating the measuring tape or adjusting the measurement posture. The opening direction of the "C"-shaped limiting plate 306 is opposite to that of the push-in entrance 304. When the marking pen is pushed, the limiting plate 306... The inner walls on both sides of 06 provide reverse constraint force to prevent the pen body from tilting due to friction. The fixing protrusion 303 of the rubber ring 302 increases the friction with the pen body, further stabilizing the pen tip direction and ensuring that the marking point corresponds accurately with the measurement value. After releasing the pull ring 207, the spring 206 releases elastic potential energy, pushes the sliding plate 204 to move in the opposite direction, and drives the marking pen to retract into the connecting frame 2. The marking pen is pushed outward from the direction of the push inlet 304. The rubber ring 302 is squeezed and deformed (the deformation cavity 305 provides compression space), so that the pen body is removed through the push inlet 304. The new pen is pushed in from the push inlet 304. The elastic restoring force of the rubber ring 302 wraps around the pen body, and the fixing protrusion 303 is embedded in the groove of the pen body to complete the quick replacement.

[0027] The pull ring 207 is positioned to fit the thumb's operating habits, allowing users to extend and retract the marker pen while holding the measuring tape without switching hands or using additional tools, significantly improving the efficiency of continuous measurement and marking operations. The preload of the spring 206 ensures that the marker pen extends / retracts quickly, reducing operation waiting time. The translational direction of the placement groove 301 is perpendicular to the extension direction of the ruler hook, eliminating errors caused by angular deviations during traditional measuring tape marking. The rubber ring 302 absorbs the impact force during the extension and retraction of the marker pen, reducing the risk of fatigue damage to the internal parts of the connecting frame 2.

[0028] The working principle and usage process of this utility model are as follows: First, the elastic engagement mechanism between the limiting protrusion 202 and the limiting groove 102 realizes the "plug-and-play" of the connecting frame 2. Users can complete the installation or replacement without tools such as screwdrivers, significantly improving the convenience of use. Both sides of the docking plate 201 are provided with limiting protrusions 202, which form a double-point lock with the limiting groove 102 of the measuring tape body 1, effectively resisting the vibration caused by the stretching and collision of the measuring tape during use, and preventing the connecting frame 2 from falling off or shifting. When marking is required after measurement, the user holds the measuring tape body 1 with one hand and pulls the pull ring 207 with the thumb or forefinger. The pulling force is transmitted to the sliding plate 204 through the pull rod 205, overcoming the elastic force of the spring 206, and driving the sliding plate 204 to move horizontally along the sliding groove 203 to the outside of the connecting frame 2. The sliding plate 204 drives the connecting plate 3 to move synchronously, so that the marking pen in the placement groove 301 extends out of the connecting frame 2, with the pen tip exposed on the outside of the ruler hook retraction point. Because the direction of the horizontal movement of the placement groove 301 is the same as the horizontal movement of the connecting plate 2, the user can easily mark the connecting frame 2. The ruler hook is stretched vertically, allowing the user to directly push the marker pen horizontally to the target scale line without rotating the measuring tape or adjusting the measurement posture. The opening direction of the "C"-shaped limiting plate 306 is opposite to that of the push-in port 304. When the marker pen is pushed, the inner walls on both sides of the limiting plate 306 provide a reverse constraint force to prevent the pen body from tilting due to friction. The fixing protrusion 303 of the rubber ring 302 increases the friction with the pen body, further stabilizing the pen tip direction and ensuring that the marking point corresponds accurately with the measurement value. After releasing the pull ring 207, the spring 206 releases its elastic potential energy, pushing the sliding plate 204 to move in the opposite direction, causing the marker pen to retract into the connecting frame 2. Pushing the marker pen outward from the push-in port 304 causes the rubber ring 302 to deform under pressure (the deformation cavity 305 provides compression space), allowing the pen body to come out through the push-in port 304. Pushing a new pen in from the push-in port 304, the elastic restoring force of the rubber ring 302 wraps around the pen body, and the fixing protrusion 303 is embedded in the groove of the pen body, completing the quick replacement.
