DETAILED DESCRIPTION

[0026] Embodiments of the present application are described below in detail, examples of which are shown in the drawings, wherein the same or similar notations represent the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present application, and cannot be understood as a limitation of the present application.

[0027] Reference is made below Figures 1-4 A horizontally adjustable Q switch fixing device is provided according to embodiments of the present application.

[0028] As Figures 1-4 shown, the present application provides a horizontally adjustable Q switch fixing device, comprising: a base 1, a support 2 and a threaded pair 3; the base 1 comprises an adjusting part 11 and a fixing part 12, the fixing part 12 is used to fix the Q switch; the threaded pair 3 is installed on the support 2 along the horizontal plane where the base 1 is located, the threaded pair 3 comprises a sleeve 31 and a screw 32, the screw 32 comprises an extension part 321, the extension part 321 abuts against the adjusting part 11, and the length of the extension part 321 is adjustable.

[0029] When adjusting the angle of the Q switch 100, the screw 32 is rotated, the length of the extension part 321 is adjusted, the screw 32 is extended towards the adjusting part 11, an acting force is applied to the adjusting part 11 of the base 1, the base 1 is pushed to rotate on the horizontal plane, the Q switch 100 installed on the fixing part 12 is also rotated, and the angle adjustment of the Q switch 100 in the horizontal direction is realized. It can be understood that when the screw 32 is rotated in the opposite direction, the screw 32 is retracted towards the direction away from the adjusting part 11, the acting force applied to the adjusting part 11 of the base 1 is reduced, and then the base 1 can rotate in the opposite direction. In summary, by rotating the screw 32 of the threaded pair 3, the rotation of the base 1 on the horizontal plane is realized, and the angle adjustment of the Q switch 100 installed on the base 1 in the horizontal direction is realized.

[0030] Referring to Figure 1 , Figure 2 and Figure 3 , the threaded pair 3 and the support 2 are threadedly connected, specifically, the sleeve 31 of the threaded pair 3 assembly is fixed to the mounting hole of the support 2, the screw 32 is threadedly connected with the threaded hole of the inner wall of the sleeve 31, and the length adjustment of the screw 32 towards or away from the adjusting part 11 of the base 1 is realized. In some embodiments, the screw 32 is a flat head screw.

[0031] In one embodiment, the adjusting portion 11 is arranged at one side of the base 1, and the base 1 is easily changed in angle when the threaded pair 3 applies or reduces force to the adjusting portion 11.

[0032] The first extension portion 111 is arranged at the outer side of the adjusting portion 11, and the second extension portion 211 is arranged at the same side of the bracket 2 as the first extension portion 111, and the first extension portion 111 and the second extension portion 211 are elastically connected by the spring 4, which can play a role of buffering and positioning during the angle adjustment of the base, and the gap between the bracket 2 and the base 1 is kept relatively constant by elastic deformation, which avoids the rotation angle of the base 1 exceeding the preset range and ensures the stability of the Q-switch during operation.

[0033] The Q-switch fixing device is integrally installed on a substrate (not shown in the figure), and the bracket is fixed to the substrate by the first bolt assembly 21. It can be understood that the substrate can be any component that can be used to install the Q-switch and its fixing device in the optical path of the laser, and is usually the base or bottom plate of the laser. The substrate is provided with mounting hole positions corresponding to the mounting components such as the Q-switch fixing device, so that the Q-switch fixing device is.

[0034] The base further comprises a second bolt assembly 13, which comprises at least one arc-shaped through hole 131 and at least one fixing bolt 132, each fixing bolt 132 cooperates with the arc-shaped through hole 131, and the fixing bolt 132 extends to the substrate through the arc-shaped through hole 131 and is screwed to the substrate, so that the base 1 is fixed to the substrate by the second bolt assembly 13. The arc-shaped through hole 131 has a certain length, so that the rotation and angle adjustment of the base 1 can be realized by only loosening the fixing bolt 132 without completely removing the fixing bolt 132. In some specific embodiments, the arc-shaped through hole 131 and the fixing bolt 132 that cooperate with each other can be arranged at different positions of the base 1 respectively, as long as they can cooperate with the mounting hole of the substrate. For example, the second bolt assembly 13 can be arranged at the adjusting portion 11 and the side opposite to the adjusting portion 11 of the base 1 respectively.

[0035] Referring to Figure 3Figure 2 shows the bottom structure of the Q-switch fixing device. The bracket 2 is provided with a first positioning pin 22 at the bottom for positioning the bracket on the base plate. The base 1 is provided with a second positioning pin 14 at the bottom for positioning the base 1 on the base plate. In some embodiments, the base 1 can rotate around the second positioning pin 14 in the horizontal plane where the base 1 is located, and the base 1 is rotated by adjusting the length of the extension 321 to apply a force to the adjusting part 11. After the bracket 2 is roughly fixed by the first positioning pin 22, the first bolt assembly 21 is fixed first to fix the position of the bracket 2. After the base 1 is roughly fixed by the second positioning pin 14 and the distance between the bracket 2 and the base 1 is roughly determined under the action of the spring 4, the fixing bolt 132 of the second bolt assembly 13 is slightly fixed to enable the base 1 to maintain a stable position but not be locked, and then the screw 32 of the rotating screw pair 3 is rotated to change the length of the extension 321 of the screw 32 to realize the horizontal adjustment of the base 1 and the Q-switch 100 mounted on the base 1. After the adjustment is completed to the preset angle, the fixing bolt 132 is tightened to determine the position of the base 1 and the Q-switch 100.
