As shown in Figures 1 to 5, a clip 01 with a feed port is used to buckle a slider 03 and two return structures 04 of a cross-roller linear slide 02. The slider 03 forms a through groove 032 along the axial direction, so that a rail (not shown in the figure) is slidably inserted through the slider 03. Each return structure 04 is respectively arranged at both ends of the slider 03. Two channels (not shown in the figure) are formed on both sides of the through groove 032, so that several rollers (not shown in the figure) run inside the channel. The channels extend in each return structure 04 to form a circulation shape. Each channel is staggered and disconnected inside the return structure 04. The channel forms a return interval (not shown in the figure) inside the return structure 04. Each return structure 04 is respectively penetrated by a through hole 042, and the through hole 042 is connected to the return interval, so that the roller is placed in the channel through the through hole 042. The return structure 04 has a first side (not shown in the figure) and a second side 044. The first side is opposite to the second side 044, and the first side is adjacent to the slider 03.

The fastener 01 includes a first baffle 10, a second baffle 20 and a connecting strip 30, wherein one end of the connecting strip 30 is integrally connected to the first baffle 10, and the other end of the connecting strip 30 is integrally connected to the second baffle 20, the first baffle 10 and the second baffle 20 are respectively adjacent to each second side 044, and the first baffle 10 and the second baffle 20 are respectively adjacent to the reflux interval laterally, thereby fastening the slider 03 and each reflux structure 04 to improve the bonding strength between the reflux structure 04 and the slider 03.

A first material inlet 40 is formed through the first baffle plate 10 , and a second material inlet 50 is formed through the second baffle plate 20 , so that the rollers can enter each channel through the first material inlet 40 and the second material inlet 50 .

Through the above-mentioned structural composition morphology and technical characteristics, the first baffle plate 10 and the second baffle plate 20 relatively limit the slider 03 and each reflux structure 04, thereby buckling the slider 03 and each reflux structure 04; the slider 03 and each reflux structure 04 are limited and positioned between the first baffle plate 10 and the second baffle plate 20, and the first baffle plate 10 and the second baffle plate 20 are respectively adjacent to the reflux interval laterally. When the roller runs through the reflux interval in the channel, the roller forms a sharp turning operation in the reflux interval, and the roller forms a relative force on the reflux structure 04, so that the intensity of the force is F, and the speed of the relative movement of the slider 03 and the rail is V, F is positively correlated with V, the first baffle plate 10 and the second baffle plate 20 are respectively located in the direction of the force, the first baffle plate 10 and the second baffle plate 20 respectively provide support for each reflux structure 04, and improve the bonding strength between the reflux structure 04 and the slider 03, accordingly, under the premise of maintaining effective bonding between the slider 03 and each reflux structure 04, the speed limit of the relative movement of the slider 03 and the rail is improved.

The linear slide rail 02 may further have two covers 06, each cover 06 is adjacent to each reflux structure 04, and the first baffle 10 and the second baffle 20 are respectively located between the reflux structure 04 and the cover 06, each cover 06 is respectively matched with each through hole 042 to protrude two embedded blocks 062, each embedded block 062 is respectively embedded in each through hole 042 through the corresponding first feed port 40 and second feed port 50, thereby closing the through hole 042; the cover 06 may be a scraping brush structure with an oil scraping function.

The connecting strip 30 is adjacent to one side of the through slot 032 through the slider 03, and the connecting strip 30 forms a first wing 31 and a second wing 32. The first wing 31 and the second wing 32 are symmetrical to each other, and a 90° angle is formed between the first wing 31 and the second wing 32. The connecting strip 30 further forms a connecting piece 33, and the two sides of the connecting piece 33 are respectively connected to the first wing 31 and the second wing 32 as a whole.

A first curved retaining edge 34 is provided at the end of the first wing 31, and the first retaining edge 34 extends in a direction away from the second wing 32. A second curved retaining edge 35 is provided at the end of the second wing 32, and the second retaining edge 35 extends in a direction away from the first wing 31. When the roller runs in the channel and passes through one side of the through groove 032, the first retaining edge 34 and the second retaining edge 35 respectively form a stop for the end of the roller facing the through groove 032.

In this example, the roller is a cylinder, the through groove 032 cooperates with the axial section of the roller to be a long rectangular hole, the first feed port 40 and the second feed port 50 are respectively long rectangular holes, so that the roller enters each channel through the first feed port 40 and the second feed port 50; the width of the first feed port 40 and the second feed port 50 in the length direction is greater than the through groove 032, the first feed port 40 has two first short sides 42, each first short side 42 is opposite to each other, and two first virtual lines 44 are defined to extend respectively along the tangent direction of each first short side 42, and the first blocking edge 34 is toward the first baffle 10.
