[0025] A mounting mechanism with an adjustable mounting method is also provided on one side surface of the housing 1, and the mounting mechanism comprises: a mounting plate 6, and the mounting plate 6 is fixedly mounted on one side surface of the housing 1;

[0026] A light-emitting component is arranged between the marking mechanism and the mounting mechanism, and the light-emitting component is composed of an irradiation component and a driving component;

[0027] An inner frame 20 is also provided at the center of the shell 1. The inner frame 20 is located at the center of the limiting frame 15. The four side surfaces of the inner frame 20 are provided with slots, and four connecting blocks 13 are provided inside the slots. Four telescopic motors 11 are also provided on one side surface of the shell 1. The surface of the telescopic motor 11 is sleeved with a motor protection shell 5. The output shaft of the telescopic motor 11 passes through the opening provided on the surface of the limiting frame 15 and is connected to the side surface of the connecting block 13. A target body 4 is fixedly installed on one side surface of the connecting block 13. The four target bodies 4 are arranged in such a stacking manner. One side surface of the four target bodies 4 is provided with matching marks. An auxiliary target 14 is fixedly installed on one side surface of the inner frame 20 through a fixed card block. One side surface of the auxiliary target 14 is provided with an auxiliary mark matching the mark on the surface of the target body 4.

[0028] When in use, the four target bodies 4 are driven to move outward or inward by contracting the four telescopic motors 11, and cooperate with the auxiliary target 14 behind the target body 4 to change the mark on the surface of the target body 4, so as to expand or reduce the mark. When reducing the mark, the four telescopic motors 11 push the connecting block 13 inward to stack the four target bodies 4, so as to reduce the mark. When expanding the mark, the four telescopic motors 11 can be contracted to drive the connecting block 13 and the four target bodies 4 to move, and cooperate with the four target bodies 4 at the rear to make the mark into a complete shape, so as to expand the mark.

[0029] The irradiation component includes: a lighting tube 16, a light is provided at one end of the lighting tube 16, a trigger switch 18 for controlling the switch of the lighting tube 16 is fixedly installed on the surface of the other end of the lighting tube 16, a limiting ring 17 is sleeved on one side surface of the lighting tube 16, and the limiting ring 17 is fixedly installed on one side surface of the auxiliary target 14 by bolts, and the lighting tube 16 can rotate inside the limiting ring 17, and a meshing gear 8 is sleeved on the surface of the lighting tube 16, and a battery 7 is provided inside the housing 1, and the battery 7 is connected to the lighting tube 16 through a cable, and a touch block 19 matching the trigger switch 18 is provided on the side surface of the battery 7 opposite to the lighting tube 16;

[0030] When in use, the drive motor 10 is controlled by a remote signal, so that the drive motor 10 drives the drive gear 9 to rotate, and the engagement of the drive gear 9 with the meshing gear 8 drives the lighting tube 16 to rotate, and the trigger switch 18 on one side of the lighting tube 16 and the pressure block 19 on the side of the battery 7 are pressed to trigger the switch of the lighting tube 16. When the trigger switch 18 and the pressure block 19 are pressed, the drive motor 10 stops rotating and fixes the position of the trigger switch 18, so that the trigger switch 18 remains in the pressed state, and the lighting tube 16 emits light to illuminate the surface of the target body 4 and the auxiliary target 14. Because the surfaces of the target body 4 and the auxiliary target 14 are only marked with light-transmitting materials, in a dark environment, the marks will emit light, achieving the purpose of facilitating observation;

[0031] The driving component includes: a driving motor 10, which is fixedly mounted on the upper surface of the housing 1, a driving gear 9 is sleeved on the output shaft of the driving motor 10, the driving gear 9 is meshed with the meshing gear 8, and a protective shell is arranged outside the driving motor 10 for isolating the driving motor 10 from the outside;

[0032] Mounting holes are provided on both sides of the mounting plate 6, and a hidden groove is provided on the surface of the mounting plate 6 on the side opposite to the housing 1, and a rotatable hidden mounting piece 12 is provided inside the hidden groove, and a pull block is also provided on one side surface of the hidden mounting piece 12 for facilitating the removal of the hidden mounting piece from the hidden groove, and an axis body is provided at the connection between the hidden mounting piece 12 and the mounting plate 6, and an adjustment knob is provided on one side surface of the axis body for adjusting the flexibility of the hidden mounting piece 12;

[0033] When in use, the device can be installed on a horizontal or vertical wall surface by installing the plate 6 or folding out the hidden installation sheet 12, or the device can be clamped on the top of a thinner horizontal board by adjusting the adjustment knob and using the mounting plate 6 or the hidden installation sheet 12.

[0034] In this embodiment, in an environment with good light, due to the obvious markings of the target body 4 and the auxiliary target 14, the operator can easily identify the position of the target. In the case of poor light or precise positioning, the lighting strip 3 can provide sufficient light to make the target more eye-catching. The target bodies 4 are arranged in a stacked manner, and each target body 4 is provided with matching markings on its surface. These markings can help the operator quickly identify different parts or different positions of the target. The auxiliary markings on the surface of the auxiliary target 14 cooperate with the markings on the target body 4, further enhancing the identifiability of the target. By driving the telescopic motor 11, the connecting block 13 and the target body 4 can adjust their positions, thereby changing the marking state or shape of the target according to actual needs.

[0035] The light inside the lighting tube 16 provides lighting to ensure that the target is still clearly visible in an environment with insufficient light. The trigger switch 18 is used to control the switch state of the lighting tube 16. The operator can turn on or off the lighting function at any time as needed. The battery 7 provides power for the lighting tube 16 to ensure the continuous operation of the lighting function. The touch block 19 cooperates with the trigger switch 18. When the cable between the battery 7 and the lighting tube 16 is connected, the touch block 19 will press the trigger switch 18 to turn on the lighting tube 16.

[0036] The driving motor 10 drives the lighting lamp tube 16 to rotate inside the limiting ring 17 through the engagement of the driving gear 9 with the meshing gear 8, thereby adjusting the lighting direction of the lighting lamp tube 16. The protective shell isolates the driving motor 10 from the outside world to protect the driving motor 10 from interference or damage from the external environment. The coordinated use of the hidden mounting piece 12 and the mounting plate 6 provides a variety of installation methods for the target. The operator can adjust the flexibility of the hidden mounting piece 12 by adjusting the knob according to actual needs, and then fix the target in a suitable position.

[0037] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
