[0043] Example 1: A tool for measuring and marking the height of a boot shaft

[0044] like Figure 1 and Figure 2 As shown, this embodiment includes a base 1 for placing the boot shaft, a ruler 2 rotatably mounted on the base 1, a slider 3 slidably mounted on the ruler 2, and a marker 4 detachably mounted in the middle of the slider 3. In use, the marker 4 is fixed at the height where the boot shaft needs to be marked by adjusting the height of the slider 3, the boot shaft is then placed on the base 1, and lines are drawn using the marker 4.

[0045] Specifically, such as Figure 4As shown, the base 1 is rectangular structure, the upper surface is provided with a groove 5 for receiving the scale 2 and a receiving slot 6 for receiving the slider 3. In order to ensure that the boot can be placed on the base 1 to complete the height measurement and line drawing operation, the embodiment also provides an extension platform 7. As shown Figure 1 As shown, the height of the extension platform 7 is equal to the base 1, and the length is slightly smaller than the base 1. In order to ensure that the boot can be placed on the base 1 to complete the height measurement and line drawing operation, the embodiment also provides an extension platform 7. As shown Figure 1 The "front" and "back" marked in the middle are references. When using the embodiment, the extension platform 7 is usually connected to the rear side of the base 1, and is used to expand the area of the upper surface of the base 1.

[0046] As shown Figure 2 The "left" and "right" marked in the middle are references. The bottom of the scale 2 in the embodiment is rotatably connected to the right side of the groove 5 in the base 1 through the connecting shaft 8. By rotating the scale 2 to the left, the scale 2 can be stored in the groove 5 of the base 1.

[0047] Further, the embodiment is provided with a first positioning mechanism for positioning the scale 2 in a vertical state on the base 1. The first positioning mechanism includes a first hole 9 provided on the base 1, a second hole 10 provided on the scale 2, and a wave screw for being provided in the first hole 9 and the second hole 10. As shown Figure 4 As shown, the first hole 9 is located directly above the connecting shaft 8 of the base 1 and the scale 2; as shown Figure 5 As shown, the center line of the second hole 10 and the connecting shaft 8 is located in the length direction of the scale 2. When the scale 2 is rotated to be perpendicular to the base 1, the second hole 10 coincides with the first hole 9, and the wave screw 12 is provided in the second hole 10 and the first hole 9, so that the scale 2 can be fixed in a vertical state on the base 1. For details, please refer to Figure 2 .

[0048] As shown Figure 4 The "left" and "right" marked in the middle are references. The base 1 of the embodiment is also provided with a third hole 11 on the left side of the base 1 and the connecting shaft 8 of the scale 2. The third hole 11 is matched with the wave screw 12. When the scale 2 is rotated to the left to be stored in the groove 5 of the base 1, the second hole 10 coincides with the third hole 11, and the wave screw 12 is provided in the second hole 10 and the third hole 11, so that the scale 2 can be fixed in a horizontal state in the groove 5 of the base 1. For details, please refer to Figure 3 .

[0049] As shown Figure 5As shown, the slider 3 is a rectangular block, the bottom surface is a plane, and is provided with a rectangular hole penetrating from top to bottom for the scale 2 to pass through. In this embodiment, the slider 3 is provided with a second positioning mechanism for fixing the slider 3 relative to the scale 2. The second positioning mechanism comprises a positioning hole 13 provided on the slider 3, the positioning hole 13 being perpendicular to the surface of the scale 2; further comprises a top block 14 slidingly assembled in the positioning hole 13 and having a first end portion facing the surface of the scale 2, and a compression spring 15 sleeved on the top block 14 and limited in the positioning hole 13. Under the elastic action of the compression spring 15, the first end portion of the top block 14 always extends out of the positioning hole 13 and abuts against the surface of the scale 2, which can be referred to as the fixed state of the slider 3 relative to the scale 2. Figure 6a and Figure 6b .

[0050] In this embodiment, the second end portion of the top block 14 is fixedly provided with a pull ring 16, so as to facilitate the worker to pull the top block 14 out of the positioning hole 13 through the pull ring 16.

[0051] Further, the top block 14 is provided with a first protrusion 17 extending in the radial direction at a position close to the second end portion, and the length of the first protrusion 17 is less than the hole diameter of the positioning hole 13. As shown, Figure 7 the slider 3 is provided with two second protrusions 18 opposite to each other at the hole opening of the positioning hole 13, and the gap between the two second protrusions 18 can allow the first protrusion 17 to pass through. When it is needed to adjust the slider 3 and the scale 2 to the active state, the top block 14 is first rotated after holding the pull ring 16, so that the first protrusion 17 on the top block 14 is aligned with the gap between the two second protrusions 18, and then the top block 14 is pulled out until the first end portion of the top block 14 is retracted into the positioning hole 13, which can be referred to as the active state of the slider 3 relative to the scale 2. Figure 8a and Figure 8b Finally, the top block 14 is rotated so that the first protrusion 17 is latched on the two second protrusions 18, so that the first end portion of the top block 14 cannot be re-abutted against the side surface of the scale 2 under the action of the compression spring 15, which can be referred to as the fixed state of the slider 3 relative to the scale 2. Figure 7 When it is needed to adjust the slider 3 and the scale 2 to the fixed state, the top block 14 is rotated after holding the pull ring 16, so that the first protrusion 17 on the top block 14 is re-aligned with the gap between the two second protrusions 18, and at this time the first end portion of the top block 14 will be re-abutted against the surface of the scale 2 under the action of the compression spring 15, which can be referred to as the active state of the slider 3 relative to the scale 2. Figure 6a and Figure 6b Finally, the top block 14 is rotated so that the first protrusion 17 is misaligned with the gap between the two protrusions.

[0052] As shown, Figure 5 the slider 3 is provided with a cylindrical mounting seat 19 and a positioning ring 20 for assembling the marker pen 4. Specifically, with Figure 5 “left” and “right” in the figure as references, the cylindrical mounting seat 19 is fixedly provided at the center position of the left side wall of the slider 3, and Figure 9As shown, the center of the cylindrical mounting seat 19 is provided with a mounting hole for inserting the marker pen 4, the outer side wall of the cylindrical mounting seat 19 is provided with a thread, and a plurality of through grooves 21 are formed on the side wall of the cylindrical mounting seat 19 in the circumferential direction, all the through grooves 21 extend along the axial direction of the cylindrical mounting seat 19 from the top end of the cylindrical mounting seat 19, so that the top end of the cylindrical mounting seat 19 forms a multi-petal structure. The inner side wall of the positioning ring 20 is provided with a second thread matched with the thread on the cylindrical mounting seat 19. In use, the tail end of the marker pen 4 is inserted into the cylindrical mounting seat 19, and then the positioning ring 20 is screwed on the cylindrical mounting seat 19. Under the limitation of the positioning ring 20, the "multi-petal structure" of the cylindrical mounting seat 19 will shrink to the middle, thereby forming a fastening to the tail end of the marker pen 4.

[0053] When the slider 3 is assembled on the scale 2, and the marker pen 4 is assembled on the slider 3, the marker pen 4 is perpendicular to the scale 2.

[0054] It should be noted that in the embodiment, the scale values of the scale 2 increase from bottom to top, and the zero scale value of the scale 2 is below the upper surface of the base 1. The scale value corresponding to the upper surface of the base 1 is equal to the vertical length from the center of the slider 3 to the bottom surface of the slider 3, so as to eliminate the influence of the volume of the slider 3 on the measured value. When the boot cylinder is placed on the base 1 for measurement, the scale value corresponding to the bottom surface of the slider 3 is the height of the line drawn on the boot cylinder.

[0055] It should be noted that the above only describes the preferred embodiments of the present application, and is not intended to limit the present application. Although the present application has been described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments, or equivalently replace some technical features.
