[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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. At the same time, it should be understood that the specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0018] like Figure 1 As shown, the utility model provides a laser fixed adjustment platform, including a base 12 and a laser launching platform 11, wherein the laser launching platform 11 is mounted on the base 12 via a first screw 21, and the base 12 is mounted on a bottom plate (not shown in the figure) via a second screw 22, and an adjusting screw 23 for adjusting the height of the base 12 on the bottom plate is also installed between the base 12 and the bottom plate.

[0019] In actual operation, the bottom plate is the bottom plate of a probe-type confocal endoscope (not shown in the figure), and both the first screw rod 21 and the second screw rod 22 can be bolts.

[0020] During actual work, when it is necessary to ensure that the laser emission direction of the laser launching station 11 meets the assembly accuracy requirements of the laser launching station 11 in the probe-type confocal endoscope, the staff only needs to install the other components of the probe-type confocal endoscope first, and then determine the laser emission direction of the laser launching station 11 along the direction of the reverse light path, thereby determining the installation position of the laser launching station 11 on the base plate, and finally install the base 12 on the base plate according to the installation position (through the second bolt). Finally, the staff can package the laser launching station 11 in the confocal endoscope. In this way, the present application also ensures that the laser emission direction of the laser launching station 11 meets the assembly accuracy requirements.

[0021] In actual work, when it is necessary to ensure that the laser emission height of the laser launching platform 11 meets the assembly accuracy requirements of the laser launching platform 11 in the probe-type confocal endoscope, the staff can adjust the height of the base 12 on the bottom plate by adjusting the screw rod 23, thereby realizing a preliminary adjustment (coarse adjustment) of the laser emission height of the laser launching platform 11, and can also adjust the height of the laser launching platform 11 on the base 12 by the first screw rod 21, thereby realizing a secondary adjustment (fine adjustment) of the laser emission height. In this way, under the joint action of the above-mentioned first screw rod 21 and the adjusting screw rod 23, the staff can adjust the laser emission height of the laser launching platform 11 to a suitable position, thereby ensuring that the laser emission height of the laser launching platform 11 meets the assembly accuracy requirements.

[0022] The rear end of the base 12 is provided with two adjusting screws 23, and the front end of the base (12) is provided with one adjusting screw 23, and the two adjusting screws at the rear end and the adjusting screw at the front end are arranged in an isosceles triangle. In this way, under the action of the above three adjusting screws 23, the present application can adjust the height and side tilt angle of the laser launch platform 11 on the base 12, thereby realizing fine adjustment of the position of the laser launch platform 11.

[0023] Two second screws 22 are arranged at the front end of the base 12, and one second screw 22 is arranged at the rear end of the base 12. The two second screws 22 at the front end and the second screw 22 at the rear end are arranged in an isosceles triangle, and the second screws 22 and the adjusting screw 23 are arranged alternately on the base 12. In this way, the present application not only has a more beautiful structure, but also can realize the height adjustment function of the base 12.

[0024] The base 12 is provided with a step at the position where the second screw rod 22 is installed, and the second screw rod is installed in the groove 13 formed by the step. In this way, the space on the base 12 for placing the second screw rod 22 will be larger, and the second screw rod 22 will be more convenient to disassemble and install.

[0025] At least four fixing grooves 14 are arranged on the laser emitting platform 11, and the first screw rod 21 is arranged in each fixing groove 14. In this way, the present application can not only fix the base 12 on the bottom plate, but also make the structure more compact and beautiful.

[0026] In other embodiments, Figure 2 As shown, further, on the basis of the above embodiment, the laser launch station 11 is provided with a laser positioning component 3 for guiding the laser emission direction of the laser launch station 11, and a bubble level 4 for indicating the level of the laser launch station 11. The laser positioning component 3 is mainly used to accurately position the laser emission direction of the laser launch station 11, and the level 4 is mainly used to ensure that the laser emission direction of the laser launch station 11 is in a horizontal state. In this way, under the joint action of the laser positioning component 3 and the level 4, the present application can not only further accurately position the laser emission direction of the laser launch station 11, but also allow the staff to quickly find the accurate installation position of the laser launch station 11, making the present application more convenient to use.

[0027] The laser positioning assembly 3 includes an infrared generator 31 installed on the housing of the laser launch station 11. The infrared rays emitted by the infrared generator 31 are coplanar with the laser emission direction of the laser launch station 11 on the vertical plane. In this way, the staff can find the laser emission direction of the laser launch station 11 more quickly according to the direction indicated by the infrared generator 31, so as to fine-tune the direction of the laser launch station. Since each screw hole and screw rod has a tolerance, the laser emission direction only needs to be fine-tuned. Of course, the mounting holes on the bottom plate can also be made into a waist-shaped structure to make the direction adjustment easier, thereby making the application more convenient to use.

[0028] The bubble level 4 is arranged on the upper surface of the laser emitting platform 11 . The bubble level 4 is a commonly used tool in the art and will not be described in detail here.

[0029] The above are only preferred embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
