[0045] As some embodiments of the present application, one of the fifth measuring scale 45 and the sixth measuring scale 46 may be the same measuring scale as the second measuring scale 42 , so as to reduce the number of measuring scales to be provided.

[0046] Therefore, through the measuring device 100 of the present application, the positions of the first link 20, the second link 30 and the measuring scales provided on the first link 20 and the second link 30 can be adjusted, so that the size of the target object can be measured by multiple measuring scales, which is beneficial to improving the measurement efficiency and the accuracy of the measurement results.

[0047] In some embodiments of the present invention, Figure 1-Figure 3 As shown, the multiple measuring rulers include: a first measuring ruler 41 and a second measuring ruler 42.

[0050] Specifically, due to the height direction of the measuring device 100 (i.e. Figure 1 The first link 20 and the second link 30 are both movable relative to the frame 10. By adjusting the first link 20 and the second link 30 along the height direction (i.e. Figure 1 By adjusting the position of the first measuring ruler 41 on the first connecting rod 20 and the position of the second measuring ruler 42 on the second connecting rod 30, the first measuring ruler 41 and the second measuring ruler 42 can clamp the target object to measure the height dimension of the target object through the first measuring ruler 41 and the second measuring ruler 42.

[0051] As some optional embodiments of the present application, after the first measuring ruler 41 and the second measuring ruler 42 are moved into place, the distance between the first connecting rod 20 and the second connecting rod 30 can be manually measured to measure the height dimension of the target object. As some optional embodiments of the present application, after the first connecting rod 20 and the second connecting rod 30 are moved into place, the height dimension of the target object can be obtained by reading the scale provided on the frame 10. As some optional embodiments of the present application, a tape measure is sleeved on one of the first connecting rod 20 and the second connecting rod 30, and the end of the tape measure is connected to the other of the first connecting rod 20 and the second connecting rod 30, and the height dimension of the target object can be obtained directly by reading the scale of the tape measure. As some optional embodiments of the present application, one end of a ruler is fixedly provided on one of the first connecting rod 20 and the second connecting rod 30, and the height dimension of the target object can be obtained directly by reading the scale of the ruler.

[0052] This arrangement can be used to measure the position along the height direction of the measuring device 100 (i.e. Figure 1 The positions of the first measuring ruler 41 and the second measuring ruler 42 can be adjusted along the Z direction as shown in the figure, and the position of the first measuring ruler 41 can be adjusted along the extension direction of the first connecting rod 20 according to the part to be measured, and the position of the second measuring ruler 42 can be adjusted along the extension direction of the second connecting rod 30 according to the part to be measured, so that the height dimension of the target object or a part of the target object can be obtained quickly and accurately, which is beneficial to improving the measurement efficiency of the height dimension and the accuracy of the measurement result.

[0053] In some embodiments of the present invention, Figure 1-Figure 3As shown, the first measuring ruler 41 is rotatable relative to the first connecting rod 20, and the second measuring ruler 42 is rotatable relative to the second connecting rod 30. In the process of measuring the height dimension of the target object, the first measuring ruler 41 and the second measuring ruler 42 can be rotated so that the positions of the first measuring ruler 41 and the second measuring ruler 42 fit the upper and lower ends of the part to be measured, thereby facilitating further improving the measurement efficiency of the height dimension and the accuracy of the measurement result.

[0054] In some embodiments of the present invention, Figure 1-Figure 3 and Figure 5 As shown, the measuring device 100 further includes: a first slider 51 and a second slider 52, wherein the first connecting rod 20 may have a slide rail, the slide rail on the first connecting rod 20 extends along the extension direction of the first connecting rod 20, the first slider 51 is movably disposed on the slide rail on the first connecting rod 20, and the first measuring ruler 41 is rotatably disposed on the first slider 51. Furthermore, the second connecting rod 30 may have a slide rail, the slide rail on the second connecting rod 30 extends along the extension direction of the second connecting rod 30, the second slider 52 is movably disposed on the slide rail on the second connecting rod 30, and the second measuring ruler 42 is rotatably disposed on the second slider 52.

[0055] As some embodiments of the present application, Figure 5 As shown, the first slider 51 may have a first pivot shaft 511, and the first measuring scale 41 may have a first pivot hole, which may be pivotally matched with the first pivot shaft 511 on the first slider 51, so that the first measuring scale 41 is rotatably provided on the first slider 51. As some embodiments of the present application, the second slider 52 may have a second pivot shaft, and the second measuring scale 42 may have a second pivot hole, which may be pivotally matched with the second pivot shaft on the second slider 52, so that the second measuring scale 42 is rotatably provided on the second slider 52.

[0056] Such an arrangement enables the first measuring scale 41 to move smoothly along the extension direction of the first connecting rod 20 and to rotate smoothly relative to the first connecting rod 20, and enables the second measuring scale 42 to move smoothly along the extension direction of the second connecting rod 30 and to rotate smoothly relative to the second connecting rod 30, thereby improving the reliability of the measuring device 100.

It can be understood that since the matching slider 60 is a standard part and can be purchased directly, by using the matching slider 60, the first slider 51 and the second slider 52 only need to be able to be fixedly connected with the corresponding matching slider 60 and can be matched with the corresponding measuring ruler, and it is not necessary for the first slider 51 and the second slider 52 to have a structure that matches the slide rail, which can reduce the processing difficulty of the first slider 51 and the second slider 52, and improve the processing efficiency of the first slider 51 and the second slider 52.

[0058] As some embodiments of the present application, the first slider 51 can directly cooperate with the slide rail on the first connecting rod 20 for sliding motion (the first slider 51 is directly and movably arranged on the slide rail on the first connecting rod 20), and the second slider 52 can directly cooperate with the slide rail on the second connecting rod 30 (the second slider 52 is directly and movably arranged on the slide rail on the second connecting rod 30).
