[0002] A laser beam analysis device is a device used to analyze and evaluate the characteristics of laser beams. It is commonly used in scientific research, industrial manufacturing, and laser technology development, aiming to quantify and characterize various parameters and performances of laser beams. A laser beam analysis device can evaluate the spatial distribution, wavefront shape, beam diameter, divergence angle, etc. of the beam. These parameters are very important for determining the beam quality and optimizing beam focusing and beam bunching.
[0003] Generally, a movable carriage is provided on a laser beam analysis device. Workers can adjust the distance between the laser emitter and the spot acquisition device by adjusting the position of the carriage. However, the adjustment of the carriage is generally achieved through bolts, and rapid adjustment of the carriage position cannot be realized. Adjusting with bolts means that each time the position of the carriage is adjusted, the bolts need to be loosened or tightened. This process usually requires tools and is relatively time-consuming. Especially when multiple fine adjustments are required, the operation will appear inefficient.

Specific Embodiments
[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.
[0018] Referring to Figures 1-3 , a laser beam analysis device includes a guide rail 1. Three sliding seats 2 are slidably arranged on the guide rail 1. A spot recording device 3, a lens 4, and a laser emitting device 5 are respectively installed on the three sliding seats 2. The lens 4 is located between the spot recording device 3 and the laser emitting device 5. The specific structure and working principle of this laser beam analysis device are not the innovative part of this technical solution and are not shown in the figure and will not be elaborated here; Each sliding seat 2 is connected to the guide rail 1 through an adjustment structure. The adjustment structure includes a slotted groove 61, an opening 62, a locking block 63, a rotating block 64, a limiting groove 65, a limiting block 66, a spring 67, a rotating rod 68 and a torsion spring 69. The slotted groove 61 and the opening 62 are both formed on the sliding seat 2, and the slotted groove 61 communicates with the opening 62. The locking block 63 is slidably disposed in the slotted groove 61. One end of the locking block 63 close to the guide rail 1 is provided with an arc surface adapted to the guide rail 1, and anti-slip lines are arranged on the arc surface. The rotating block 64 is rotatably disposed in the slotted groove 61. The rotating block 64 and the locking block 63 together form a cylindrical structure. The rotating block 64 and the locking block 63 are of the same size. One end of the rotating block 64 and the locking block 63 opposite to each other are both provided with inclined surfaces. The outer edges of the rotating block 64 and the locking block 63 are both in mutual contact with the inner surface of the slotted groove 61. The limiting groove 65 is formed on the groove wall of the slotted groove 61. The limiting block 66 is fixed on the locking block 63, and the limiting block 66 is slidably disposed in the limiting groove 65. One end of the spring 67 is connected to the groove wall of the limiting groove 65, and the other end of the spring 67 is connected to the limiting block 66. The rotating rod 68 is rotatably installed in the opening 62. One end of the rotating rod 68 extends into the interior of the slotted groove 61 and is fixedly connected to the rotating block 64. One end of the torsion spring 69 is connected to the sliding seat 2, and the other end is connected to the rotating rod 68. The end of the rotating rod 68 away from the rotating block 64 extends outside the opening 62 and is fixed with a knob. The staff can release the limit of the locking block 63 on the sliding seat 2 by rotating the knob, so as to realize the rapid adjustment of the position of the sliding seat 2. This design facilitates the staff to quickly adjust the positions of the light spot recording device 3, the lens 4 and the laser emitting device 5, and is convenient for the flexible detection of the quality of the laser beam; A pressing structure is arranged on the guide rail 1. The pressing structure includes a mounting frame 71, a threaded rod 72, a guide rod 73 and a pressing plate 74. The mounting frame 71 is fixed on the side surface of the guide rail 1, and the mounting frame 71 is in an L-shaped structure. The threaded rod 72 passes through the mounting frame 71, and the threaded rod 72 is threadedly sleeved with the mounting frame 71. The guide rod 73 passes through the mounting frame 71, and the guide rod 73 is slidably connected with the mounting frame 71. One end of the threaded rod 72 is rotatably connected with the pressing plate 74. A handle is installed at the end of the threaded rod 72 away from the pressing plate 74. One end of the guide rod 73 is fixedly connected with the pressing plate 74. The pressing plate 74 is arranged opposite to the three sliding seats 2. The staff rotates the handle to make the threaded rod 72 rotate. Under the limiting action of the guide rod 73, the threaded rod 72 can drive the pressing plate 74 to move when rotating until the pressing plate 74 presses the three sliding seats 2. When the pressing plate 74 presses the three sliding seats 2, the pressing plate 74 can play a fixing role on the three sliding seats 2, avoiding the three sliding seats 2 from moving on the guide rail 1 during the transfer process and ensuring the stability of the sliding seats 2 on the guide rail 1.
[0019] The specific working principle of the present invention is as follows: When the laser beam analysis device proposed by the present invention is in use, the staff can quickly adjust the position of the sliding seat 2 through the adjustment structure. Specifically, the staff first rotates the knob, which drives the rotating rod 68 to rotate. When the rotating rod 68 rotates, it can drive the rotating block 64 to rotate. Since the rotating block 64 and the locking block 63 together form a cylindrical structure, the rotating block 64 and the locking block 63 are of the same size, and inclined surfaces are provided at the opposite ends of the rotating block 64 and the locking block 63. The outer edges of the rotating block 64 and the locking block 63 are in mutual contact with the inner surface of the slot 61. Therefore, during the rotation of the rotating block 64, its inclined surface part can squeeze the inclined surface part of the locking block 63. Under the limiting action of the limiting groove 65 and the limiting block 66, the locking block 63 cannot follow the rotating block 64 to rotate. So the locking block 63 will move under the squeezing action of the rotating block 64. Therefore, when the rotating block 64 rotates, the rotating block 64 no longer squeezes the locking block 63, and the locking block 63 will move away from the guide rail 1 under the elastic force of the spring 67, so that the locking block 63 is separated from the guide rail 1. Without the pressing of the locking block 63, the sliding seat 2 can move freely on the guide rail 1. When the staff loosens the knob, the rotating rod 68 will reset under the elastic force of the torsion spring 69, causing the rotating block 64 to rotate in the reverse direction. The reverse rotation of the rotating block 64 enables the locking block 63 to press the guide rail 1 again, fixing the position of the sliding seat 2 on the guide rail 1. Therefore, the staff can release the limit of the locking block 63 on the sliding seat 2 by rotating the knob, thereby realizing the quick adjustment of the position of the sliding seat 2. This design facilitates the staff to quickly adjust the positions of the light spot recording device 3, the lens 4 and the laser emitting device 5, and is convenient for flexible detection of the laser beam quality. Further, reference lines can be set on the knob and the sliding seat 2 to facilitate the staff to flexibly control the rotation angle of the knob; A pressing structure for fixing the positions of the three sliding seats 2 is also provided on the guide rail 1. When the staff needs to transfer the beam analysis device, the staff can use the pressing structure to fix the positions of the three sliding seats 2. Specifically, the staff rotates the handle, causing the threaded rod 72 to rotate. Under the limiting action of the guide rod 73, the threaded rod 72 can drive the pressing plate 74 to move when it rotates until the pressing plate 74 presses the three sliding seats 2. When the pressing plate 74 presses the three sliding seats 2, the pressing plate 74 can fix the three sliding seats 2, preventing the three sliding seats 2 from moving on the guide rail 1 during the transfer process and ensuring the stability of the sliding seat 2 on the guide rail 1.
