[0031] See also Figure 1 , Figure 1 1 is a schematic diagram of a hole distance measuring device in some embodiments of the present application. The hole distance measuring device 100 is applied to a product X to be measured, and the product X to be measured includes a plurality of holes O to be measured.

[0032] The hole distance measuring device 100 includes a plurality of fixing components 10 and a measuring member 11. Each fixing component 10 includes a fixing seat 101 and a fixing member 102; the fixing seat 101 is provided with through holes 1011 and first grooves 1012 spaced apart along a first direction, and the through holes 1011 and the first grooves 1012 at least partially overlap.

[0033] The fixing member 102 and the through hole 1011 are spaced apart along a second direction which is perpendicular to the first direction. One end of the fixing member 102 abuts against the fixing seat 101 , and the other end of the fixing member 102 passes through the hole O of the product X to be tested.

[0034] At least part of the measuring member 11 is disposed in the overlapping first grooves 1012 and through holes 1011 on the plurality of fixing seats 101 , so that the measuring member 11 measures the hole distance between any two holes O to be measured through the through holes 1011 .

[0035] It can be understood that the first direction is perpendicular to the second direction, the first direction corresponds to the X-axis, and the second direction corresponds to the Y-axis or the Z-axis; or, the first direction corresponds to the Y-axis, and the second direction corresponds to the X-axis or the Z-axis; or others, which are not limited here. In some embodiments of the present application, the first direction is marked with symbol ①, and the second direction is marked with symbol ②.

[0036] It can be understood that when the measuring piece 11 is placed on the first groove 1012, since the first groove 1012 and the through hole 1011 overlap, the value displayed on the measuring piece 11 can be observed through the through hole 1011 of the overlapping part, and then the hole distance between any two holes O to be measured can be measured based on the displayed value.

[0037] In some embodiments of the present application, the hole distance measuring device 100 uses a fixing member 102 to pass through the hole O to be measured of the product X to be measured, and passes the hole O to be measured through the fixing member 102. The fixing member 102 can fix the hole O to be measured to prevent the hole O to be measured from moving randomly, and the measuring member 11 is set on the first groove 1012. On the one hand, the first groove 1012 can be used to fix the measuring member 11 to prevent the instability of the measuring member 11 during the measurement process from affecting the measurement result. On the other hand, since the first groove 1012 partially overlaps with the through hole 1011, when the measuring member 11 is set on the first groove 1012, the value displayed by the measuring member 11 can be directly observed through the through hole 1011, thereby determining the hole distance between at least two holes O to be measured. The hole distance measuring device 100 is used to measure the hole distance of the product X to be measured. The operation is simple and the measurement efficiency is high. The hole O to be measured is fixed by the fixing member 102 and the measuring member 11 is arranged in the first groove 1012. This can ensure that the distance between any two holes to be measured is the same as the distance between the measuring member 11 on the corresponding two first grooves 1012, and the measurement result has a high accuracy.

The fixing member 102 can fix the hole O to be measured to prevent the hole O to be measured from moving at will, and the measuring member 11 is set on the first groove 1012. On the one hand, the first groove 1012 can be used to fix the measuring member 11 to prevent the instability of the measuring member 11 during the measurement process from affecting the measurement result. On the other hand, since the first groove 1012 partially overlaps with the through hole 1011, when the measuring member 11 is set on the first groove 1012, the value displayed by the measuring member 11 can be directly observed through the through hole 1011, thereby determining the hole distance between at least two holes O to be measured. The hole distance measuring device 100 described above is used to measure the hole distance of the product X to be measured, which is simple to operate, efficient, and has a high accuracy in the measurement result.

[0070] The above description is only an implementation method of the present application, and does not limit the patent scope of the present application. Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
