[0038] It should also be further understood that the term "and / or" as used in this specification and the appended claims refers to any combination of one or more of the associated listed items and all possible combinations, and includes such combinations.

[0039] Please see Figures 1 to 5 As shown, a cross roller precision slide includes: a movable stage 3, with two side guide rails 6 inside the movable stage 3, a main guide rail 1 in the middle of the two side guide rails 6, roller limiting strips and multiple rollers between the side guide rails 6 and the main guide rail 1, multiple through holes 15 on the top of the side guide rails 6, multiple through slots 2 on the top of the movable stage 3, connecting rods 4 inside the through slots 2, the bottom of the connecting rods 4 located inside the through holes 15, movable grooves 16 inside the side guide rails 6, sliding strips 10 slidably connected inside the movable grooves 16, and multiple fixing slots 8 on the top of the movable strips 10. An arc-shaped extrusion block 12 is fixed inside the fixing groove 8. An annular extrusion groove 14 is opened on the outer side wall of the connecting rod 4. A push screw 9 is screwed into the side guide rail 6. The side guide rail 6 and the moving table 3 are connected. The connecting rod 4 is inserted into the through groove 2. The bottom end of the connecting rod 4 passes through the insertion hole 15 and the fixing groove 8. Then, the push screw 9 is rotated. The push screw 9 pushes the moving bar 10. The moving bar 10 moves with the arc-shaped extrusion block 12. The arc-shaped extrusion block 12 is inserted into the annular extrusion groove 14. The annular extrusion groove 14 is squeezed to fix the connecting rod 4, thereby connecting the moving table 3 and the side guide rail 6. This connection is convenient.

[0040] In this embodiment, a push spring 13 is fixed inside the right side of the movable groove 16. When the push screw 9 is reversed, the push spring 13 pushes the moving bar 10, causing the arc-shaped extrusion block 12 and the annular extrusion groove 14 to separate, thereby removing the connecting rod 4 and separating the moving platform 3 from the side guide rail 6. A spring groove 17 is provided on the right side of the moving bar 10. The left end of the push spring 13 is fixedly connected to the left side of the inside of the spring groove 17, so that the push spring 13 can be stored. Multiple mounting holes 5 are provided on the top of the moving platform 3, so that the moving platform 3 and other objects can be installed. Multiple countersunk holes 7 are provided on the top of the main guide rail 1, so that the main guide rail 1 can be installed, and the screws installed can enter the interior of the countersunk holes 7 to prevent the screws from protruding.

[0041] like Figure 6As shown, the push screw 9 includes a screw rod 914. A circular block 912 is integrally formed on the left side of the screw rod 914. A hexagonal hole 911 is formed on the left side of the circular block 912. The screw rod 914 and the side guide rail 6 are fixedly connected. A hexagonal wrench is inserted into the hexagonal hole 911. Rotating the hexagonal wrench causes the circular block 912 and the screw rod 914 to rotate, thereby moving the screw rod 914 to push the moving strip 10. An annular groove 11 is formed inside the side guide rail 6 on the outer wall of the screw rod 914. Two fixing holes 904 are provided on the outer side wall of 914. A fixing plate 913 is fixed inside the fixing holes 904. A moving rod 910 is slidably connected inside the fixing plate 913. A plug block 909 and a top block 906 are fixed at both ends of the moving rod 910, respectively. A circular groove 908 is provided on the right side of the interior of the hexagonal hole 911. A compression spring 907 is fixed inside the circular groove 908. A top rod 902 is fixed at the other end of the compression spring 907. The outer side wall of the top rod 902... An annular groove 903 is provided. A hexagonal plate 901 is fixed to the left end of the push rod 902. The hexagonal plate 901 is located inside the hexagonal hole 911. A return spring 905 is sleeved on the outside of the moving rod 910 between the top block 906 and the fixed plate 913. The elastic force of the compression spring 907 is greater than the sum of the elastic forces of the two return springs 905. Thus, when the hexagonal wrench is inserted into the hexagonal hole 911, it will push the hexagonal plate 901, and the hexagonal plate 901 will move the push rod 902. The movement of rod 902 aligns the annular groove 903 with the fixing hole 904. This causes the return spring 905 to push the top block 906, the moving rod 910, and the insert block 909 to move. The insert block 909 enters the fixing hole 904. Then, the hex wrench is turned, and after the screw 914 is tightened, the hex wrench is removed. The compression spring 907 pushes the top rod 902 to move, which in turn moves the top block 906. The top block 906 then moves the moving rod 910 and the insert block 909. The insert block 909 inserts into the annular retaining groove 11 to prevent the screw 9 from reversing and loosening.

[0042] In summary, compared with the prior art, the cross roller precision slide has at least the following beneficial effects: The present invention uses a push screw 9 to push the moving bar 10, the moving bar 10 moves with the arc-shaped extrusion block 12, the arc-shaped extrusion block 12 is inserted into the interior of the annular extrusion groove 14, and the annular extrusion groove 14 is extruded to fix the connecting rod 4, thereby connecting the moving table 3 and the side guide rail 6 without the need to turn multiple screws, making the connection convenient.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
