Furthermore, the first rail 10 is provided with a first hole 13, with the stop arm 63 relative to the first hole 13, and the second rail 20 is provided with a stop arm 23, the stop arm 23 supporting the guide section 362, the operation of the stop arm 63 can move towards the guide section 362 through the first hole 13, the guide section 362 has a bending area 3621, the bending area 3621 is conducive to guiding the stop arm 63 to the abutment position; the first rail 10 has a baffle 14, the baffle 14 is located in the first hole 13.

[0156] like Figure 4A , Figure 4B As shown, a third rail 70 is an outer frame. The third rail 70 is provided with a second hole 71 and a rear stop 701. When the first rail 10 is unfolded in the third rail 70, the stop arm 63 springs back into the second hole 71, causing the hook 363 to disengage from the stop arm 63. Or when the first rail 10 is retracted in the third rail 70, the rear stop 701 blocks the first rail 10.

[0157] like Figure 4C , Figure 4D , Figure 4E and Figure 4FAs shown, the actuating part 51 includes a first protruding rib 511 and / or a second protruding rib 512. The first protruding rib 511 has a first actuating surface D1 and / or the second protruding rib 512 has a second actuating surface D2. The first actuating surface D1 contacts the first arched surface A1 and / or the second actuating surface D2 contacts the second arched surface A2. It also has three functions: First, a floating distance H is formed between the operating cover 50 and the first rail 10, so that the operator can intuitively press the operating cover 50; Second, the first arched surface A1 abuts against the first actuating surface D1 or... The second arched surface A2 rests against the second actuating surface D2, causing the first hook surface B1 to engage with the first stop surface 411 or the second hook surface B2 to engage with the second stop surface 421, so that the operator can stably engage the positioning feature 40 with the spring piece 30; the first actuating surface D1 presses against the first arched surface A1 or / and the second actuating surface D2 presses against the second arched surface A2, so that the first spring piece 32 is inside the first elongated hole 21 or / and the second spring piece 33 is inside the second elongated hole 22, so that the pressing stroke is increased, so that the operator can easily press the operating cover 50.

[0158] Continuing on the above, the opening portion 11 has a first opening 111 and / or a second opening 112, with the first protruding rib 511 passing through the first opening 111 to contact the first elastic member 32, causing the first protruding rib 511 to press against the first elastic member 32 and the first hook portion 321 to disengage from the first buckle portion 41, and / or the second protruding rib 512 passing through the second opening 112 to contact the second elastic member 33, causing the second protruding rib 512 to press against the second elastic member 33 and the second hook portion 331 to disengage from the second buckle portion 42. Furthermore, the first rail 10 forms a contact surface 15 between the first opening 111 and the second opening 112, with the concave surface E21 opposite to the contact surface 15, so that the operating cover 50 can be pressed and stably abutted against the first rail 10.

[0159] like Figure 4G As shown, taking the first buckle 41 as an example, when the first elastic member 32 is extended with the second rail 20, the first sliding surface C1 passes through the first guide surface 412, and then the first hook surface B1 hooks onto the first stop surface 411; or when the protective cover 50 presses the first elastic member 32, the first hook surface B1 disengages from the first stop surface 411; as shown Figure 4H As shown, taking the second buckle 42 as an example, when the second spring 33 closes with the second rail 20, the second sliding surface C2 passes through the second guide surface 422, and then the second hook surface B2 hooks onto the second stop surface 421, or when the protective cover 50 presses the second spring 33, the second hook surface B2 disengages from the second stop surface 421.

[0160] like Figure 4I , Figure 4J , Figure 4K , Figure 4L , Figure 4M , Figure 4N As shown, a slide 80 is provided on the first rail 10. The slide 80 has a fastening hole 81 and an auxiliary surface 82. The second rail 20 is movable relative to the first rail 10 and the slide 80, so that the fastener 521 is relative to the slide 80. The fastener 521 fastens the fastening hole 81 or disengages from the fastening hole 81. When the slide 80 is movable and presses against the first stop F1, the first stop F1 rebounds at the fastening hole 81 and the second stop F2 abuts against the auxiliary surface 82 to fix the position of the slide 80 on the first rail 10. The second rail 20 is provided with a release feature 24. The release feature 24 is relative to the second stop F2. When the second rail 20 is retracted toward the first rail 10, the release feature 24 releases the fastening between the second stop F2 and the slide 80, so that the fastener 521 can be integrated into the operating cover 50 to increase the multi-functionality of the component. In addition, the first stop body F1 has an inclined surface F11, which facilitates the movable displacement of the slide block 80 and presses against the first stop body F1.

[0161] Continuing from the above, the front end of the first rail 10 is provided with a support member 90, and the rear end of the support member 90 has at least one abutment feature 91. The slide 80 has at least one horizontal plate 83 and a first predetermined feature 84. When the second rail 20 is unfolded on the first rail 10, it moves the slide 80 toward the support member 90, causing the horizontal plate 83 to contact the abutment feature 91. Therefore, the fastener 521 and the abutment feature 91 complement each other, effectively fixing the slide 80 on the first rail 10. Alternatively, the hook 36 relative to the first predetermined feature 84, when the second rail 20 is unfolded on the first rail 10, the second rail 20, in conjunction with the hook 36, contacts the first predetermined feature 84. Feature 84 drives the slide 80, and the contact method is hooking, abutting, or rubbing. The first predetermined feature 84 is formed by bending the slide 80, and cooperates with the slide 80 to open a first groove 85 and a second groove 86 opened on the side of the first groove 85. The first predetermined feature 84 has a stop surface 841 and a guide surface 842 opposite to the stop surface 841. The position of the stop surface 841 corresponds to the second groove 86 and the guide surface 842 corresponds to the first groove 85. The opening of the first groove 85 and the second groove 86 sets the position of the stop surface 841 and the guide surface 842. The hook 363 is relative to the stop surface 841 and contacts the stop surface 841. The first rail 10 has a second predetermined feature 16, and the second rail 20 has a predetermined space 26. The first predetermined feature 84 is displaced toward the second predetermined feature 16, and the second predetermined feature 16 is located below the first predetermined feature 84. When the second predetermined feature 16 contacts the hook 36, the hook 36 moves toward the predetermined space 26, and the first predetermined feature 84 disengages from the hook 36. Further, the abutment arm 23 is located within the predetermined space 26 and abuts against or supports the guide section 362 and the hook body 363. The second predetermined feature 16 is a protrusion, and the protrusion contacts the guide section 362. The hook 363 disengages from the stop surface 841 and the guide section 362, crossing the first predetermined feature 84, allowing the first rail 10 to be pulled out of the second rail 20. The size of the opening 12 and the slot 17 can adjust the friction area of ​​the protrusion. The protrusion is located on the first longitudinal wall 101 of the first rail 10, and the guide section 362 is located on the second longitudinal wall 202 of the second rail 20. The contact method is that the protrusion abuts against the guide section 362, and friction is generated between the protrusion and the guide section 362. Conversely, when the second rail 20 advances into the first rail 10, the guide section 362 passes through the guide surface 842 to the side of the stop surface 841. In addition, the bending area 3621 facilitates the guidance of the second predetermined feature 16 or the guide surface 842.

[0162] Next, the second rail 20 is disengaged from the first rail 10. When the second rail 20 is reinserted into the first rail 10, it can avoid impacting the slide block 80. Then, the front end of the support member 90 has at least one spring-shaped feature 92, and the second rail 20 has at least one transverse wall 25. The transverse wall 25 can be aligned with the spring-shaped feature 92 to insert the second rail 20 into the support member 90. Then, the second rail 20 abuts against the slide block 80 into the first rail 10, and the slide block 80 retracts to the baffle 14. Therefore, the spring-shaped feature 92 makes it easy for the operator to visually align and insert the rail. Furthermore, the back of the support member 90 has at least one abutment feature 93. When the first rail 10 is retracted into the third rail 70, the abutment feature 93 abuts against the third rail 70, creating a gap between the first rail 10 and the third rail 70. This prevents components on the first rail 10 from colliding with components or the body of the third rail 70, thus facilitating the smooth retraction of the first rail 10 into the third rail 70. In addition, Figures 1A to 4N As shown, a plurality of fasteners I are used to fix each of the components. Each of the fasteners I can be a screw or rivet, or each of the components can be directly formed on the rails without fasteners I. Each of the components is on the rails as described above, and will not be described in detail.
