Embodiments of the invention

[0012] The present invention will be further described below with reference to the accompanying drawings, and the scope of protection of the present invention is not limited to the following

[0013] As shown in FIG. 1 and FIG. 2, a fine adjustment mechanism capable of adjusting movement in a vertical direction includes a rotating shaft 5, a rotating disk 1 mounted on the rotating shaft 5, a support frame 9, a screw 8, and a rotating disk 1 above the fixed disk 2, the rotating disk 1 has a notch 7 therein, and the notched 7-side rotating disk 1 is provided with a threaded hole 11, the threaded portion 82 of the screw 8 is screwed with the threaded hole 11, the optical axis of the screw 8 The portion 81 is connected to the optical hole of the support frame 9. The nut of the screw 8 is in close contact with the support frame 9 and the screw 8 is rotatable. The support frame 9 is fixedly mounted on the rotatable support frame rotating shaft 13, and the rotating plate 1 is mounted with a plurality of transmissions. Column 6, the fine adjustment block B4 is installed above the transmission column 6, as shown in Fig. 3, the bottom of the fine adjustment block B4 is provided with a chute 41, the transmission column 6 is located in the chute 41, and the fixing plate 2 has a plurality of limiting slots 3 In this embodiment, the number of the limiting slots 3 is the same as the number of the transmission posts 6, and the limiting slots The length of the third slot is greater than the length of the trimming block B4, and the width of the limiting slot 3 is equal to the width of the trimming block B4. In this embodiment, the distance between the upper surface of the rotating disk 1 and the upper surface of the fixed disk 2 is less than the fine adjustment. The height of the block B4, the fine adjustment block B4 is located in the limit slot 3, the fine adjustment block A1 is arranged above the fine adjustment block B4, the fine adjustment block Al1 is installed in the limit channel 12, and the fine adjustment block B4 is wedge-connected with the fine adjustment block Al1.

[0014] The working process of the present invention is as follows: The screw 8 is rotated, since the threaded hole 11 of the rotating disk 1 is to be screwed with the threaded portion 82, but the optical axis portion 81 of the screw 8 is connected to the optical hole of the support frame 9 and the screw 8 The nut abuts against the support frame 9, causing the screw 8 to not move, and the rotary disk 1 can only achieve the engagement of the threaded hole 11 with the threaded portion 82 by its own rotation.

[0015] The rotation direction of the rotating disk 1 can be changed by changing the rotation direction of the screw 8, since the support frame 9 is fixedly mounted on the rotatable support frame rotating shaft 13, whereby the support frame 9 can be rotated by the support frame rotating shaft 13 to compensate Rotation of the rotating disk 1 causes deflection of the screw 8 such that the axis of the screw 8 coincides with the axis of the threaded hole in the rotating disk 1 at all times.

[0016] Since the rotating disk 1 rotates, the transmission column 6 rotates together with the rotating disk 1. When the transmission column 6 rotates, the transmission column 6 slides in the chute 41, because the fine adjustment block B4 is restricted in the limiting slot 3, when The transmission column 6 will slide in the chute 41, and the fine adjustment block B4 will move along the limiting slot 3. When the fine adjustment block B4 moves, the fine adjustment block B4 is connected to the fine adjustment block Al1, and the fine adjustment block Al l can be in the limit position. Moving within the channel 12, the trimming block Al1 can be adjusted by means of a mechanism that requires adjustment of the distance in the connected device, the degree of adjustment being controlled by the degree of rotation of the screw 8.
