[0029] Reference example Figures 1 to 6A circulator for a linear guide slider comprises an outer circulator 1 and an inner circulator 2. The outer circulator 1 is provided with a concave cavity 11. Outer slide grooves 12 are provided at the upper and lower parts of both sides of the concave cavity 11. A first fixing part 13 and a second fixing part 14 are provided at both sides of the concave cavity 11. A third fixing part 15 is provided between the concave cavities 11. The inner circulator 2 is provided with an inner slide groove 21 corresponding to the outer slide groove 12. A slot 22 for the first fixing part 13 to be inserted is provided at the entrance of the inner slide groove 21. The inner circulator 2 is provided with a contact part 23 for the second fixing part 14 to abut against. A contact part 23 for the third fixing part 15 to abut against is provided between the inner slide grooves 21. The plug-in through hole 24 allows the inner circulator 2 to be embedded in the concave cavity 11, and the first fixing portion 13 is inserted into the slot 22, the second fixing portion 14 is against the abutment portion 23, and the third fixing portion 15 is inserted into the through hole, so that the outer circulator 1 and the inner circulator 2 are connected and fixed to each other. Through the above-mentioned multiple connection points, the connection between the two is ensured to be stable, and the inner circulator 2 is guided into the concave cavity 11, which reduces the time for the first fixing portion 13, the second fixing portion 14, and the third fixing portion 15 to align with the slot 22, the abutment portion 23, and the through hole 24 respectively during assembly, thereby improving assembly efficiency;

[0030] It is worth mentioning that the inner circulator 2 is provided with a hollow cage 25 for the ball chain 3 to be inserted, and is connected to the inner slide 21, so that the ball chain 3 is directly inserted into the hollow cage 25, so that the ball chain 3 moves therein;

[0031] It is worth mentioning that movable grooves 251 for the chain edge of the ball chain 3 to move are provided on both sides of the hollow retainer 25. The movable grooves 251 provide a guide for the ball chain 3 to prevent the ball chain 3 from being displaced during movement.

[0032] It is worth mentioning that the hollow retainer 25 on one side of the inner circulator 2 is provided with a protrusion 252, and the hollow retainer 25 on the other side of the inner circulator 2 is provided with a groove 253 for inserting the protrusion 252. The hollow retainer 25 is inserted into the channel of the slider body for the ball chain 3 to insert and move. The protrusion 252 is inserted into the groove 253 to connect the hollow retainers 25 to each other, thereby avoiding the chain edge of the ball chain 3 and the slider body from rubbing against each other and generating hair scraps, thereby extending the service life of the slider body;

[0033] It is worth mentioning that the inner circulator 2 is provided with a guide plate 26, and the abutment portion 23 is arranged on both sides of the guide plate 26. The guide plates 26 located on both sides of the slider body abut against each other, thereby preventing the ball chain 3 from contacting the slider body, further improving the service life of the slider body, and the abutment portion 23 is an arc-shaped fit for the ball;

[0034] It is worth mentioning that the inner circulator 2 is provided with a support block 27 which is located above the guide plate 26 . The abutment portion 23 is also provided on the inner wall of the support block 27 . The support block 27 provides a support point for the abutment portion 23 .

[0035] It is worth mentioning that the shape of the hollow retaining frame 25 is set to be fully enclosed or half-enclosed. When the hollow retaining frame 25 is fully enclosed, it can provide protection for the ball chain 3. When the hollow retaining frame 25 is half-enclosed, the manufacturing cost of the inner circulator 2 is reduced. One end of the ball of the ball chain 25 abuts against the inner wall of the slider, and the other end abuts against the half-enclosed shape. Hollow retaining frames 25 of different shapes are used according to customer needs.

[0036] The above design scheme can make the product have the advantages of convenient assembly, long service life and prevention of ball chain displacement.

[0037] The above content is a further detailed description of the utility model in combination with specific implementation methods. It cannot be determined that the specific implementation of the utility model is limited to these descriptions. For ordinary technicians in the technical field to which the utility model belongs, without departing from the concept of the utility model, they can also make several simple deductions or substitutions, which should be regarded as belonging to the scope of protection determined by the claims submitted for the utility model.
