[0052] The second adjusting mechanism is used for adjusting the second plate body 2 on the horizontal plane, including horizontal movement and deflection. The first adjusting piece 41 and the second adjusting piece 42 include an adjusting rod 51, an adjusting sleeve 52 and a fixing sleeve 55. The adjusting sleeve 52 is sleeved on the outer periphery of the adjusting rod 51. The adjusting rod 51 has an external thread, and the inner wall of the adjusting sleeve 52 has an internal thread. The external thread and the internal thread are matched with each other for driving the adjusting rod 51 to move. The structures of the first adjusting piece 41 and the second adjusting piece 42 are basically the same, and both are used for driving the adjusting rod 51 to move through thread cooperation.

One second direction moving part 62 is included in each first side adjusting part, and two second direction moving parts 62 are included in each second side adjusting part.

The two ends of the end face of the side plate 32 are provided with the second adjusting mechanisms, so that the movement of the second plate body 2 along the Y axis (synchronous adjustment of the two second adjusting mechanisms) or the deflection of the second plate body 2 in the horizontal plane (asynchronous adjustment of the two second adjusting mechanisms) is controlled through the adjustment of the two second adjusting mechanisms.

[0058] The first reset member 81 is perpendicular to the plate body, and is used to pull the second plate body 2 in the vertical direction to the bottom plate 31.

The limiting rods 92 are parallel or perpendicular to the plate body, and are fixed on the plate body and move synchronously with the plate body to stretch the elastic member. The two limiting rods 92 of the first reset member 81 are respectively located on the bottom plate 31 and the second plate body 2, and the elastic member 91 of the first reset member 81 penetrates the bottom plate 31 and the second plate body 2. The two limiting rods 92 of the second reset member 82 are respectively located on the side plate 32 and the second plate body 2. The limiting rods 92 are used to fix the two ends of the elastic member 91 to the plate body, so that the elastic member 91 is stretched during adjustment, and then the plate body is pulled close and recovered by the restoring force of the elastic member 91. The first plate body 1 and the second plate body 2 are provided with accommodating grooves 93 for accommodating the elastic member 91, and the size of the accommodating grooves 93 is greater than the size of the elastic member 91, so as to avoid interference between the elastic member 91 and the plate body when the plate body is deflected. For example, the accommodating groove 93 corresponding to the second reset member 82 on the second plate body 2 is provided in a trapezoidal shape, and the opening is directed to the side plate 32.

[0060] The optical adjustment system of the multi-degree-of-freedom manual adjustment platform includes the above, one of the first plate body 1 or the second plate body 2 is used to be fixed on the platform, and the remaining one of the first plate body 1 or the second plate body 2 is used to install the optical element. A plurality of mounting holes 10 are provided on the first plate body 1 and the second plate body 2, and the first plate body 1 or the second plate body 2 can be fixed and installed according to actual needs, or the optical element can be installed.

The second plate body 2 is an adjusting seat, and the mounting holes 10 on the adjusting seat can be used to install the optical element or the laser accessory to be adjusted on the adjusting seat. Then, the mounting seat and the adjusting seat are combined together by the five tension springs (the first reset member 81 and the second reset member 82) to form the four-dimensional adjustment platform. That is, the multi-degree-of-freedom manual adjustment platform in the embodiment at least includes four-dimensional adjustment: Y-axis, Z-axis, pitch angle (Z-axis deflection), and yaw angle (horizontal deflection).

[0061] The following briefly describes the adjustment process of the multi-degree-of-freedom manual adjustment platform in the embodiment:

[0062] 1) Horizontal deflection

[0063] The adjustment of the yawing angle is made by rotating the adjustment rod 51 of one of the second adjustment members 42 on the side plate 32 against the second plate body 2, and the second plate body 2 is horizontally deflected.

[0064] 2) Y-axis horizontal movement

[0065] The forward adjustment of the Y-axis is made by simultaneously rotating the adjustment rod 51 of both of the second adjustment members 42 on the side plate 32 clockwise against the side of the second plate body 2.

[0066] The backward adjustment of the Y-axis is made by simultaneously rotating the adjustment rod 51 of both of the second adjustment members 42 on the side plate 32 counterclockwise, and then pulling back by the second reset member 82.

[0067] 3) Pitching deflection

[0068] The adjustment of the pitching angle is made by rotating the adjustment rod 51 of the first side adjustment member or the second side adjustment member on the side plate 32 clockwise against the corresponding first direction moving member 61, moving the first direction moving member 61 in the moving cavity 311, and pushing forward to drive the second direction moving member 62 to move upward against the second plate body 2.

[0069] 4) Z-axis movement

[0070] The upward adjustment of the Z-axis is made by simultaneously rotating the adjustment rod 51 of both of the first side adjustment member and the second side adjustment member on the side plate 32 clockwise against the corresponding first direction moving member 61, moving the first direction moving member 61 in the moving cavity 311 forward, pushing forward to drive the second direction moving member 62 to move upward against the second plate body 2, and making the second plate body 2 move upward at the same rate.

[0071] The downward adjustment of the Z-axis is made by simultaneously rotating the adjustment rod 51 of both of the first side adjustment member and the second side adjustment member on the side plate 32 counterclockwise against the corresponding first direction moving member 61, moving the first direction moving member 61 in the moving cavity 311 backward, and then pulling back by the first reset member 81.

[0072] The multi-degree-of-freedom manual adjusting platform of the present application changes the force direction by setting the first adjusting mechanism, so that when the second plate body 2 needs to move in the vertical direction, it can be adjusted in the horizontal direction by the first adjusting piece 41, thereby reducing the occupied space of the adjusting platform in the vertical direction, compact structure, high space utilization, and simple adjustment.
