[0002] With the continuous advancement of electron microscopy imaging technology, microscopes are increasingly widely used in semiconductor detection, micro / nano manufacturing, and bioanalysis. In practical applications, to achieve multi-angle and omnidirectional adjustments to samples or observation angles, the microscope itself typically needs to be equipped with a support device capable of multi-degree-of-freedom adjustment to adapt to observation needs under different working conditions. Especially in scenarios requiring frequent adjustments to angles and positions to obtain optimal imaging results, multi-dimensional adjustment mechanisms have become an indispensable component of microscope systems; their flexibility, stability, and adjustment precision directly affect experimental efficiency and observation accuracy.

[0003] In the prior art, the adjustment device of the microscope generally adopts the method of fixing the microscope body to a single hinge arm or universal joint structure. However, its adjustment path is short and the number of moving units is small, which leads to structural limitations and insufficient adjustment range during the adjustment process of large angles or complex postures, and cannot achieve continuous, multi-axis linkage spatial adjustment.

[0004] Therefore, there is a need to provide a microscope multidimensional adjustment device to solve the problem of insufficient adjustment flexibility and range of existing adjustment devices. Utility Model Content

The two ends of the reinforcing rib are respectively connected to the two first connecting arms.

[0009] Furthermore, C-shaped second connecting arms extend from both ends of the second movable member, one of which is hinged to the first connecting arm. A second weight-reducing hole extending along the width direction of the second movable member is provided in the middle of the second movable member, and the length of the second weight-reducing hole is greater than the length of the opening of the second connecting arm.

[0010] Furthermore, one end of the third movable member extends with a protruding connecting arm, which is hinged to the second connecting arm.

[0021] Reference Figures 1 to 2 This utility model proposes a multi-dimensional adjustment device for a microscope, including a support 1, a microscope assembly 2 and an adjustment mechanism 3, wherein the two ends of the support 1 are respectively connected to the microscope assembly 2 and the adjustment mechanism 3; The adjustment mechanism 3 includes a first adjustment component 31 that swings about a first axis and a second adjustment component 32 that swings about a second axis. The first adjustment component 31 includes a fixed frame 311. One end of the fixed frame 311 is hinged to a first movable member 312. The other end of the first movable member 312 is hinged to a second movable member 313. The other end of the second movable member 313 is hinged to a third movable member 314. One end of the second adjustment component 32 is fixedly connected to the third movable member 314, and the other end of the second adjustment component 32 is connected to the bracket 1.

[0022] In the above embodiments, the microscope multi-dimensional adjustment device includes a support 1, a microscope assembly 2, and an adjustment mechanism 3. The support 1 serves as a connecting carrier between the microscope assembly 2 and the adjustment mechanism 3, with one end connected to the microscope assembly 2 and the other end connected to the adjustment mechanism 3. The support 1 can also be configured as a fine-tuning component for further adjustment of the microscope assembly 2. The microscope assembly 2 can be a stereo microscope, a metallurgical microscope, or other optical devices requiring multi-angle adjustment for observation. The adjustment mechanism 3 includes a first adjustment component 31 that can swing around a first axis and a second adjustment component 32 that can swing around a second axis. The first axis and the second axis are perpendicular to each other or arranged at a certain angle, thereby structurally forming a multi-dimensional adjustment path with two degrees of freedom, which can meet the multi-angle adjustment requirements of microscope posture in complex scenarios.

[0023] The first adjustment component 31 adopts a multi-segment hinged structure, which includes a fixed frame 311, a first movable component 312, a second movable component 313, and a third movable component 314. The fixed frame 311 is used to install on the main body of the device or to be fixedly connected to the base through a connector. One end of the fixed frame 311 is hinged to the first movable component 312, the other end of the first movable component 312 is hinged to the second movable component 313, and the other end of the second movable component 313 is hinged to the third movable component 314, realizing the series connection of multiple rotating joints. The distal end of the third movable component 314 is fixedly connected to the second adjustment component 32, and the other end of the second adjustment component 32 is connected to the support 1, thus forming an overall segmented, multi-node adjustable structural layout. The hinged connection between the above-mentioned multiple movable components can form a continuous and controllable spatial rotation path in multiple angular directions. Especially during the use of the microscope, the relative angles between the movable components can be manually adjusted, allowing the microscope component 2 to be adjusted in multiple axial directions to adapt to the imaging needs of complex sample positions or special viewing angles. The first adjustment component 31 provides a wide range of initial angle swing capability, while the second adjustment component 32 provides compensation adjustment on the other axis, enabling the adjustment device to have spatial linkage capability and high flexibility. It can not only realize the switching between coarse and fine adjustment of the microscope angle, but also effectively improve the stability of adjustment, the convenience of operation and the accuracy of final imaging by segmenting and controlling different active nodes.

[0024] refer to Figures 1 to 3 In one embodiment, the fixing frame 311 extends a C-shaped hinge arm 311a towards one end of the first movable member 312. The fixing frame 311 is hinged to the first movable member 312 via the hinge arm 311a. A trapezoidal recess 311b is provided on the side of the hinge arm 311a away from the first movable member 312, and a weight-reducing part 311c is provided on the side of the fixing frame 311 away from the recess 311b. The weight-reducing part 311c passes through the end of the fixing frame 311 away from the first movable member 312.

[0025] In the above embodiment, a C-shaped hinge arm 311a extends from the end of the fixed frame 311 facing the first movable member 312, and the hinge arm 311a is connected to the first movable member 312 by a hinge. A trapezoidal recess 311b is provided on the side of the hinge arm 311a away from the first movable member 312. The recess 311b allows the fixed frame 311 to reduce weight while providing mechanical support, thereby improving the rigidity and stability of the overall structure. The combination of the recess 311b and the weight-reducing part 311c effectively reduces the mass of the fixed frame 311, reducing the overall weight of the device while achieving sufficient strength. This helps to improve the response speed of the adjustment system and reduce inertia, especially during rapid adjustments, effectively avoiding the impact of excessive load. The weight-reducing part 311c, through its structural design that penetrates the fixed frame 311, ensures that the overall component maintains high strength and stability. At the same time, the reasonable mass distribution optimizes the center of gravity of the device, further enhancing the balance and stability of operation.

[0026] In one example, each of the opposite ends of the first movable member 312 extends a first connecting arm 312a, one of which is hinged to the hinge arm 311a. The middle of the first movable member 312 is provided with a first weight-reducing hole 312b extending along the length direction of the first movable member 312, and the middle of the first weight-reducing hole 312b is provided with a reinforcing rib 312c extending along the length direction of the first movable member 312. The two ends of the reinforcing rib 312c are respectively connected to the two first connecting arms 312a.

[0027] In the above embodiment, both ends of the first movable member 312 extend with first connecting arms 312a, one of which is hinged to a hinge arm 311a, thereby forming a multi-axis linkage adjustable structure. A first weight-reducing hole 312b is formed in the middle of the first movable member 312 along its length, and a reinforcing rib 312c extending along the length is provided in the weight-reducing hole. This design effectively reduces the weight of the first movable member 312, while the reinforcing rib 312c enhances the strength and rigidity of this part. The reinforcing rib 312c connects the first connecting arms 312a at both ends, which not only improves the load-bearing capacity of the connecting arms but also prevents deformation of the movable member due to uneven stress. Furthermore, the weight-reducing hole allows for a better balance between strength and mass when fine adjustments are required, improving the operational precision and flexibility of each component during the adjustment process.

[0028] In one embodiment, C-shaped second connecting arms 313a extend from both ends of the second movable member 313, one of which is hinged to a first connecting arm 312a. A second weight-reducing hole 313b extending along the width direction of the second movable member 313 is provided in the middle of the second movable member 313, and the length of the second weight-reducing hole 313b is greater than the length of the opening of the second connecting arm 313a.

[0029] In the above embodiment, C-shaped second connecting arms 313a extend from both ends of the second movable member 313, one of which is hinged to the first connecting arm 312a. A second weight-reducing hole 313b is formed in the middle of the second movable member 313 along its width direction. The length of this weight-reducing hole is greater than the length of the opening of the second connecting arm 313a, which can effectively reduce the weight of the second movable member 313 and optimize its structural strength. The weight-reducing hole not only reduces the mass of the movable member, but also makes the second movable member 313 more flexible during adjustment, providing more precise adjustment capabilities without affecting the load capacity. By balancing the needs of weight reduction and strength, the high efficiency of the microscope multi-dimensional adjustment device is ensured, and the response speed and stability during the adjustment process are improved, especially when adjusting complex angles, enabling more precise control of the microscope position.

[0030] In one embodiment, one end of the third movable member 314 extends a protruding connecting arm 314a, which is hinged to the second connecting arm 313a.

[0031] In the above embodiment, one end of the third movable member 314 extends with a protruding connecting arm 314a, which is hinged to the second connecting arm 313a. The design of the protruding connecting arm 314a enables the third movable member 314 to form a stable connection with the second connecting arm 313a, ensuring coordinated movement of the two during adjustment. The protruding structure of the connecting arm optimizes the force distribution at the overall connection point, effectively preventing loosening or damage caused by an insecure connection. Especially during frequent adjustments, the protruding connecting arm 314a effectively reduces friction.

[0032] refer to Figures 1 to 4 In one embodiment, the second adjustment component 32 includes an adjustment plate 321, which is fixedly connected to one end of the third movable member 314 away from the protruding connecting arm 314a, and the adjustment plate 321 has a rotation hole 321a and an arc-shaped hole 321b coaxially arranged with the rotation hole 321a. One end of the adjusting plate 321 is rotatably connected to a connecting plate 322. The connecting plate 322 is connected to the bracket 1 and rotates around the rotating hole 321a. The connecting plate 322 is connected to a clamping member 323, which is slidably disposed in the arc-shaped hole 321b. The clamping member 323 is used to abut against the end of the adjusting plate 321 away from the connecting plate 322, so as to fix the adjusting plate 321 and the connecting plate 322.

[0033] In the above embodiment, the second adjustment component 32 includes an adjustment plate 321, which is fixedly connected to the end of the third movable member 314 away from the protruding connecting arm 314a. The adjustment plate 321 has a rotating hole 321a and an arc-shaped hole 321b coaxially arranged with the rotating hole 321a. One end of the adjustment plate 321 is connected to the support 1 via a rotating connecting plate 322. The connecting plate 322 rotates around the rotating hole 321a and is connected to a clamping member 323, which is slidably disposed in the arc-shaped hole 321b. Through the relative movement of the adjustment plate 321 and the connecting plate 322, the clamping member 323 abuts against the end of the adjustment plate 321 away from the connecting plate 322, so that the relative position between the adjustment plate 321 and the connecting plate 322 can be firmly fixed after adjustment, thereby ensuring that the microscope adjustment will not produce errors due to loosening, ensuring the stability and accuracy of the adjustment plate 321, suitable for multi-axis linkage adjustment, and improving the reliability and precision of the overall structure.
