[0026] In the present invention: A semi-surrounding structure is formed between the eccentric sleeve body 1 and the eccentric hole 2, and the positioning groove 15 coincides with the vertical center line of the eccentric hole 2. The eccentric hole with a certain gap from the center point of the eccentric sleeve body can generate an eccentric force during operation, enabling the object to achieve a curvilinear motion effect. The positioning groove facilitates the determination of the position of the eccentric hole during installation.

[0027] In the present invention: A communication structure is formed between the through hole 4 and the hollow channel 3, and the through holes 4 are symmetrically distributed about the vertical center line of the eccentric sleeve body 1; Different items can be filled into the hollow channel through the through holes.

[0028] In the present invention: The hollow channels 3 are symmetrically distributed about the vertical center line of the eccentric sleeve body 1, and three groups of hollow channels 3 and through holes 4 are provided; The cooperation of the hollow channels 3 and the through holes 4 can adjust the weights of various parts of the eccentric sleeve, solving the problem that the existing eccentric sleeves are only suitable for eccentric adjustments with specific eccentric errors and cannot be adaptively modified for different eccentric errors.

[0029] In the present invention: The vertical center lines of the eccentric sleeve body 1 and the fixed sleeve 11 coincide, and the clamping plate 5 and the fixed sleeve 11 are parallel to each other; The fixed sleeve facilitates the installation and fixation of the eccentric sleeve body, and the clamping plate and the clamping groove cooperate to clamp the fixed sleeve and the eccentric sleeve body together.

[0030] In the present invention: The cross-sectional dimension of the clamping plate 5 is larger than the cross-sectional dimension of the clamping groove 16, and the material of the elastic backing plate 6 is elastic rubber material.

[0031] In the present invention: A clamping plate 5 and a fixing sleeve 11 form an elastic structure through an elastic cushion plate 6, and the clamping plate 5 and the elastic cushion plate 6 are in close contact; the elastic cushion plate can increase the tightness of the connection between the eccentric sleeve body and the fixing sleeve.

[0032] In the present invention: The structure of a movable sleeve plate 12 is a hollow structure inside, and the movable sleeve plate 12 and a fixing plate 13 form an elastic telescopic structure through a return spring 14, and the movable sleeve plate 12 and the elastic cushion plate 6 form a sliding structure through a limit sliding groove 17; the return spring can drive the movable sleeve plate to move relatively to the left and right positions of the fixing plate, thereby preventing the disconnection between the fixing sleeve and the eccentric sleeve body, and the limit sliding groove plays a role in limiting and guiding the movement of the movable sleeve plate, avoiding the problems of complex structure and cumbersome installation process of the existing eccentric sleeve.

[0033] In the present invention: A micro drive cylinder 9 and a pressing block 7 form a telescopic structure through a micro telescopic rod 10, and the pressing blocks 7 are symmetrically distributed about the vertical center line of the clamping plate 5; the micro drive cylinder 9 can drive the pressing block 7 to move downward through the micro telescopic rod 10, and the downward-moved pressing block 7 can press the clamping plate 5 tightly.

[0034] In the present invention: An elastic gasket 8 and the pressing block 7 are in close contact, and the material of the elastic gasket 8 is silicone; the elastic gasket 8 can increase the friction with the clamping plate 5, thereby improving the firmness of the installation of the eccentric sleeve body 1, and greatly increasing the practicality of this kind of adjustable eccentric sleeve.

[0035] The working principle of the easily adjustable eccentric sleeve: First, install and fix the eccentric sleeve body 1 and the fixed sleeve 11. Tighten the return spring 14, and place the part below the elastic backing plate 6 into the fixed sleeve 11 through the card slot 16. At this time, the part above the clamping plate 5 remains above the fixed sleeve 11. The return spring 14 returns to drive the movable sleeve plate 12 to move relatively to the left and right sides of the fixed plate 13, preventing the movable sleeve plate 12 from disengaging from the fixed sleeve 11. The limit sliding groove 17 plays a role in limiting and guiding the movement of the movable sleeve plate 12. Secondly, start the micro driving cylinder 9. The micro driving cylinder 9 drives the pressing block 7 to move downward through the micro telescopic rod 10 until the downward moving pressing block 7 presses the clamping plate 5 through the elastic gasket 8. The elastic gasket 8 increases the friction between the pressing block 7 and the clamping plate 5, thereby improving the firmness of the installation of the eccentric sleeve body 1. At this time, the elastic backing plate 6 increases the tightness of its connection at the middle position between the eccentric sleeve body 1 and the fixed sleeve 11, avoiding the problems of the complex structure and cumbersome installation process of the existing eccentric sleeve. Then, determine the installation position of the eccentric hole 2 through the positioning groove 15. Through the eccentric force generated by the eccentric hole 2 during operation, the object can achieve the effect of curvilinear motion. Finally, during use, add different items into the hollow channel 3 through the through holes 4 in each part as needed, so as to adjust the weights of each part of the eccentric sleeve and make adaptive changes for different eccentric errors.
