[0025] The transmission assembly includes a cylinder 2, a piston rod 3, a first fixed column 4, a rotating plate 5 and a fixed rod 6. The top of the base 1 is provided with a cylinder 2, the output end of the cylinder 2 is slidably connected with the piston rod 3, one end of the piston rod 3 is fixedly connected with the first fixed column 4, the interior of the first fixed column 4 is rotatably connected with the rotating plate 5, and the interior of the rotating plate 5 is fixedly connected with the fixed rod 6;

[0026] It also includes a first pulling rod 7, a second pulling rod 8 and a clamp 9. The surface of the rotating plate 5 is rotatably connected to the first pulling rod 7, the outside of the rotating plate 5 is rotatably connected to the second pulling rod 8, and one end of the second pulling rod 8 is rotatably connected to the clamp 9.

[0027] Among them, the central axis of the cylinder 2 coincides with the central axis of the first fixed column 4. The first fixed column 4 forms a rotating structure through the piston rod 3 and the rotating plate 5, which is conducive to more stable control of the rotating plate 5 and realizes the clamping effect during rotation.

[0028] There are two groups of clamps 9, and the two groups of clamps 9 are symmetrical with respect to the limit block 19, which is beneficial to ensure the firmness and stability of the object to be engraved during the clamping process.

[0029] Among them, the central axis of the rotating plate 5 coincides with the central axis of the fixed rod 6. The rotating plate 5 forms a rotating structure through the first fixed column 4 and the first pulling rod 7 and the second pulling rod 8, which is conducive to the rotation of the rotating plate 5 around the fixed rod 6, thereby realizing the operation control of the clamp 9, and the object does not shake during the engraving process, achieving efficient work and improving production efficiency.

[0030] Example 2

[0031] like Figure 1 , Figure 2 and Figure 4 As shown, this embodiment further illustrates Example 1, the side wall of the third pulling rod 10 is rotatably connected to the first rotating rod 11, one end of the third pulling rod 10 is rotatably connected to the pushing rod 12, the top of the base 1 is fixedly connected to a blocking column 13, one end of the pushing rod 12 is fixedly connected to a spring 14, one end of the spring 14 is fixedly connected to a pushing block 15, the outside of the pushing block 15 is slidably connected to a pushing plate 16, the side wall of the pushing block 15 is rotatably connected to the second rotating rod 17, one end of the pushing block 15 is fixedly connected to the second fixed column 18, and the top of the base 1 is fixedly connected to a limiting block 19.

[0032] The push plate 16 forms a sliding structure with the base 1 through the first rotating rod 11 , which is conducive to the push plate 16 driving the push block 15 to slide on the base 1 , driving the entire mechanism to operate, and realizing the operation control of the push block 15 .

[0033] The push block 15 forms a sliding structure with the push plate 16 through the spring 14, and the push block 15 forms a rotating structure with the second rotating rod 17 through the spring 14, which is beneficial to enhance its positioning stability, facilitate operation, and meet the needs of positioning use.

[0034] Working principle: First, driven by the cylinder 2, the first fixed column 4 pushes the rotating plate 5 to start rotating. Under the action of the rotating plate 5, the first pull rod 7 and the second pull rod 8 also start rotating with the rotating plate 5. The entire mechanism is driven to rotate by sliding, thereby realizing the operation control of the clamp 9 and completing the working principle of the clamping mechanism. In this operation process, the object being engraved is guaranteed to be firm and stable;

[0035] Finally, through the manual action of the third pulling rod 10, the third pulling rod 10 is moved between the existing position and the blocking column 13, while also ensuring the range of motion of the pushing block 15. Under the dual support of the first rotating rod 11 and the pushing rod 12, the second fixed column 18 can more firmly fix the object, so that the object does not shake or shift during engraving, thereby enhancing its stability and facilitating operation, meeting the requirements of positioning and use, and achieving efficient work and improving production efficiency.
