[0013] The beneficial effect of this improvement is that the clamping block can be pressed flat against the inner wall of the guide rail to achieve a stable locking of the sliding seat position.

[0014] To ensure that the clamping block moves stably horizontally under the push of the moving block;

[0015] As a further improvement to the above technical solution: the moving block is an isosceles trapezoidal block structure that is narrow at the top and wide at the bottom, and the sides of the two sides of the moving block slide against the sides of the clamping block.

[0022] The beneficial effect of this improvement is that, with the nut locked, the lens is securely clamped between the lower support and the upper support.

[0023] To ensure the lower support is securely locked onto the upright;

[0024] As a further improvement to the above technical solution: one end of the tightening bolt is pressed tightly against the side of the upright.

[0025] The beneficial effect of this improvement is that the tightening bolt can be pressed tightly onto the upright to lock the position of the lower support.

[0026] To prevent the lens axis from deviating from the extension direction of the guide rail;

[0035] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory, and should not be used to limit the scope of protection of the present invention in any way.

[0036] Example 1:

[0037] like Figure 1As shown in Figure 4: An optical imaging device includes a guide rail 1, on which a sliding seat 2 is slidably mounted. The sliding seat 2 includes a base 21, on which a bolt 22 is rotatably secured. The bolt 22 is threadedly connected to a moving block 23. The sides of the moving block 23 are slidably connected to the sides of clamping blocks 24. The clamping blocks 24 are slidably mounted in a through groove in the base 21. The opposing end faces of the two clamping blocks 24 are respectively connected to the two ends of a spring 25. A lens clamping member 3 is mounted on the top surface of the base 21. The lens clamping member 3 includes a vertical rod 31, on which a sliding... A lower support 32 is movably mounted, with a tightening bolt 33 threaded to one end of the lower support 32. A screw 34 is mounted on the top surface of the lower support 32, and an upper support 35 is slidably mounted on the screw 34 and threadedly connected to it with a nut 36. A lens 4 is clamped between the lower support 32 and the upper support 35. Tightening the bolt 22 allows the clamping block 24 to move inward or to the sides of the base 21, thereby conveniently and effortlessly adjusting the position of the sliding seat 2 on the guide rail 1 and locking it securely. The base 21 is a trapezoidal block structure that is narrower at the top and wider at the bottom. A dovetail groove structure for slidingly connecting the base 21 is provided on the guide rail 1. The base 21 can slide stably in the guide rail 1. The opposite end faces of the two clamping blocks 24 are flat against the inner wall of the guide rail 1. The clamping blocks 24 can be flatly and tightly pressed against the inner wall of the guide rail 1 to achieve a stable locking of the sliding seat 2. The moving block 23 is an isosceles trapezoidal block structure that is narrow at the top and wide at the bottom. The sides of the two sides of the moving block 23 slide against the sides of the clamping block 24. When the moving block 23 moves upward, it can push the clamping block 24 to move outward stably. The spring 25 is set on both sides of the moving block 23. The spring 25 is a tension spring. The clamping block 24 can move and reset under the elastic tension of the spring 25. The nut 36 is installed above the upper support 35. V-grooves 37 are provided on the facing end faces of the upper support 35 and the lower support 32. The curved side surface of the lens 4 is tangent to the inner side surface of the V-groove 37. With the nut 36 locking, the lens 4 is securely clamped between the lower support 32 and the upper support 35. One end of the tightening bolt 33 is pressed tightly against the side of the upright 31. The tightening bolt 33 can press tightly against the upright 31 to lock the position of the lower support 32. The upright 31 is a square rod structure. The upright 31 can prevent the lower support 32 from rotating when it moves, thus preventing the lens 4 from shifting in the axial direction.

[0038] The working principle of this technical solution is as follows: When installing lens 4, place lens 4 between upper support 35 and lower support 32, so that the edge of lens 4 is tangent to the inner wall of the V-groove 37 opened on upper support 35 and lower support 32. Then, tighten nut 36 so that nut 36 drives upper support 35 to press on lens 4, thereby fixing lens 4. When adjusting the height of lens 4 installed on different lens clamps 3, the operator loosens the tightening bolt 33, then slides and adjusts the position of lower support 32 on the upright 31 so that the axes of different lenses 4 are collinear, and then tightens the tightening bolt 33. Bolt 33 is tightened onto the upright 31. When adjusting the horizontal position of lens 4, the operator rotates bolt 22 to move moving block 23 downward. At this time, clamping block 24 moves to the inside of base 21 under the elastic pull of spring 25. Then, the operator can directly slide and push to adjust the position of sliding seat 2 on guide rail 1. When locking the position of sliding seat 2, the operator reverses bolt 22 to move moving block 23 upward. Clamping block 24 moves to both sides of base 21 under the push of moving block 23, and then presses tightly against the inner wall of guide rail 1 to lock the position of sliding seat 2.
