[0024] The camera light of the above-mentioned shooting device 1 passes through the adapter ring mounting hole 21 and the lens barrel 5, so that the picture of the plane where the measuring film ruler 6 is located can be captured. There are several regular or irregular scale values ​​on the measuring film ruler 6, and it is made of transparent material. At the same time, through the action of the measuring light source 22, the image of the measured object and the ruler overlapping can be obtained. By reading the scale on the ruler, the width or size of the measured object can be clearly known, so that the crack can be easily observed and measured.

[0025] In a preferred embodiment of the present invention, a base 9 is provided between the adapter ring 2 and the shooting device 1, the base 9 is a plate-like structure, the bottom surface of the base 9 is connected to the shooting device 1, the base 9 has a penetrating mounting seat tube 91, the center hole of the mounting seat tube 91 is aligned with the camera of the shooting device 1, the outer side of the mounting seat tube 91 has a thread, and the mounting seat tube 91 is connected to the adapter ring mounting hole 21 by a thread.

[0026] In a preferred embodiment of the present invention, the bottom surface of the base 9 is provided with self-adhesive glue.

[0027] The above-mentioned base 9 can be bonded to the mobile phone, which is equivalent to an external mounting base on the mobile phone. The base 9 varies according to the position and number of the mobile phone cameras, but the most important technical point is that there is a hollow mounting base tube 91 at the camera used for measurement, so that the light of the camera can pass through and reach the measuring film ruler.

[0028] In a preferred embodiment of the present invention, the measuring film ruler 6 is installed and fixed in the lens barrel 5 by installing a measuring base ring 7 and a pressure ring 8.

[0029] In a preferred embodiment of the present invention, the measuring film ruler 6 is a top-hat-shaped structure including a measuring convex surface 61 and a mounting sink 62, the mounting measuring base ring 7 is a concentric reducing tube structure including a base ring small tube 72 and a base ring large tube 71, the base ring small tube 72 cooperates with the measuring convex surface 61, the outer side surface of the base ring large tube 71 has a base ring external thread 73, the base ring external thread 73 is screwed with the internal thread of the lens barrel 5, the pressing ring 8 is sleeved on the measuring convex surface 61, the end face of the pressing ring 8 is in contact with the mounting sink 62, and the outer side surface of the pressing ring 8 is screwed with the inner side surface thread of the lens barrel 5.

[0030] In a preferred embodiment of the present invention, the height of the pressure ring 8 is smaller than the height of the measuring convex surface 61 .

[0031] The above structure achieves the goal of determining the distance between the measuring film ruler 6 and the camera through the base ring 7, and at the same time pressing it through the pressure ring 8, so that the measuring plane of the measuring film ruler 6 is the highest surface of the device, so that the measuring film ruler 6 and the object to be measured achieve a zero distance effect, thereby improving the measurement accuracy.

[0032] In a preferred embodiment of the present invention, the lens barrel 5 comprises: a telescopic outer barrel 4 and a telescopic inner barrel 3, the telescopic outer barrel 4 and the telescopic inner barrel 3 are sleeved together, and the lengths of the telescopic outer barrel 4 and the telescopic inner barrel 3 are adjustable.

[0033] The above arrangement allows the length of the lens barrel 5 to be manually or automatically extended and retracted in order to obtain the minimum imaging distance of the mobile phone or camera. The telescopic structure here can adopt the structure of existing technology, which can be manual or electric.

[0034] In a preferred embodiment of the present invention, a photosensitive device 10 is disposed on the inner wall of the telescopic outer tube 4 , a light-through hole 63 is provided on the measuring film ruler 6 at a position corresponding to the photosensitive device 10 , and the photosensitive device 10 is electrically connected to the controller 12 .

[0036] Under normal circumstances, when the control switch of the measuring device is turned on, that is, when the measurement work is ready, the light entering through the light hole 21 can reach the photosensitive element 104 through the gap of the photosensitive cylinder spring 102, thereby providing a signal for the controller 12 to turn off the measuring light source 22. When the external light is insufficient, the measured position has been determined, and the measuring device is pressed against the object to be measured at zero distance, the shading plate 103 will apply force to the photosensitive cylinder spring 102, thereby compressing it, resulting in no light passing through the photosensitive element 104. At this time, the controller 12 turns on the measuring light source 22 to provide illumination for the measurement and complete the measurement and photography.

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
