Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model is further described below in conjunction with embodiments.

[0022] Example: Reference Figure 1-Figure 4 A portable distance ruler for quality inspection includes a distance ruler body 1, a hook is provided on one side of the distance ruler body 1 and can be hung on the surface of the user's pants, so as to be convenient for carrying, and also includes: brackets 2 symmetrically fixedly installed at both ends of the winding mouth of the distance ruler body 1, the ruler strip at the winding mouth of the distance ruler body 1 slides between the two brackets 2, the two brackets 2 are provided with mounting grooves 12 on opposite sides, and the top of the bracket 2 is provided with an adjustment component;

[0023] A first tooth plate 13 is slidably arranged on one side of the mounting groove 12, and a second tooth plate 15 is slidably arranged on the other side of the mounting groove 12, and springs are arranged in the mounting groove 12, and the two springs are fixedly connected to the first tooth plate 13 and the second tooth plate 15 respectively, and an upper pressure plate 11 is fixedly arranged on one side of the first tooth plate 13, and the upper pressure plate 11 is subjected to the force of the adjusting component, and the first tooth plate 13 is moved downward on one side of the mounting groove 12 with the first tooth plate 13, and a lower pressure plate 16 is fixedly arranged on one side of the second tooth plate 15, and a linkage gear 14 is rotatably connected at the center position of the mounting groove 12, and when the first tooth plate 13 is moved downward on one side of the mounting groove 12, the second tooth plate 15 is moved upward on the other side of the mounting groove 12 with the lower pressure plate 16 through the provided linkage gear 14, so that the upper pressure plate 11 and the lower pressure plate 16 are moved toward the surface of the scale bar at the same time to limit the speed of the scale bar, and the first tooth plate 13 and the second tooth plate 15 are slid in opposite directions at the same time with the upper pressure plate 11 and the lower pressure plate 16 through the adjusting component.

[0024] The adjustment component includes a vertical plate 3 fixedly installed on the top of the bracket 2, and a slide groove is opened on the opposite side of the two vertical plates 3, and a slider 4 is arranged inside the slide groove. A cross plate 5 is arranged between the two sliders 4, and a push rod 10 is arranged on the side of the bottom end of the cross plate 5 close to the bracket 2, and a through groove is opened at the top of the bracket 2 directly below the push rod 10.

[0025] The horizontal plate 5 is pressed and moves down along the slide groove between the two vertical plates 3 under the action of the two sliders 4. During the downward movement of the horizontal plate 5, the push rod 10 at the bottom squeezes the upper pressure plate 11 through the groove, so that the upper pressure plate 11 moves downward.

[0026] A mounting plate 6 is fixedly installed on one side of the vertical plate 3 close to the through groove, and the top of the mounting plate 6 is elastically connected to a limiting rod 9. The top of one side of the limiting rod 9 is a bevel, and a through groove is provided on one side of the inside of the slide groove. A limiting groove 7 matched with the limiting rod 9 is provided on one side of the slider 4, and silicone pads are provided on the bottom surface of the upper pressure plate 11 and the top of the lower pressure plate 16.

[0027] When the slider 4 moves downward in the slide groove, one side of the bottom end of the slider 4 contacts and squeezes the inclined surface of the limit rod 9. During the squeezing process, the limit rod 9 gradually moves away from the cross plate 5. It is worth noting that in the process of the limit rod 9 moving away from the cross plate 5, the elastic part at the bottom end of the limit rod 9 is stretched to generate tension. When the limit rod 9 and the limit groove 7 on one side of the slider 4 are in a vertical state, under the tension of the elastic part, one side of the limit rod 9 is inserted into the limit groove 7 on one side of the slider 4, thereby limiting and fixing the cross plate 5. The silicone pad arranged at the bottom end of the upper pressure plate 11 and the top end of the lower pressure plate 16 can increase the friction between the bottom end of the upper pressure plate 11 and the top end of the lower pressure plate 16.
