In the U.S. Patent No. 6,155,718, the holder of the holder includes a plurality of disc-shaped spacers between the balls, and the spacer system has a circular recess corresponding to each of the balls. The pocket accommodates one side of the ball to position it. = The hopper is used to make the roll fall and the pockets are rolled to separate the balls and not to fall. However, due to the pocket force;::: the edge is in contact with the balls, so the contact area is large and the result is Ball%: And because the ball is in contact with the spacer system in a loop, the effect of oil storage but smoothness is still not ^: scraping off the 'cavity can be caused by the above-mentioned retainer in addition to the use of the pocket of the ω 士士人 t I Because of the "surgery: the direction in which the glue is shot out of the mold, the glue is easy to produce interference and the processing cost is high. 9 " High defect rate and 200804698 number M24359G" The silent type linear sliding chain T structure is improved. In the new patent case, the figure is the third figure in the figure. The device is arranged in the receiving groove of each of the spacers, and the design of the above retainer is accommodated. It is easier to demould in the process, but because the spacers are only isolated, the coating is poor, and it is easy to produce the beads. In the operation, the balls between adjacent spacers are easy to shake and vibrate. The wall of the block increases the friction during operation. And not the kind of oil groove 'and thus also the lubricating effect between the ball over entirely. SUMMARY OF THE INVENTION The conventional linear sliding retainer has the disadvantages of large friction, demolding, and poor oil lubrication. The invention discloses a linear slide retainer with a small contact surface and The coating design with better covering property solves the problem of the above retainer. In order to achieve the above object, the present invention provides a linear slide holder, a plurality of front and rear spaced apart spacers, and two connecting strips at the left and the e ends of each spacer, wherein: The spacer is provided with two or more straight beam faces on the opposite side from the left to the right. The vertical sides of each of the straight restraining faces are a flat face and a hook =® 'adjacent straight restraint system The staggered setting 'and the relatively straight-facing side of the hook face are on the (four) side (also on the opposite side); the two connecting strips are in parallel setting 'and the two connecting strips and the adjacent spacers' form a number of days for scrolling The accommodating space of the component. 5 200804698 The present invention mainly has the following two types: First, the rolling element for maintaining the ball type, the accommodation m is set to a circular shape and the opposite faces of the spacers are provided with two Straight restraint faces 'The outer end edges of the left side claw faces are curved and the left end protrudes from the right end, and the right end edge of the claw face is curved and the right end protrudes from the left end; A plurality of balls are respectively embedded in the circular accommodating space, and the outer cymbal of each of the claw faces is used to give the effect of positioning the rolling in the ball.
