[0035] That is, when the pull rod structure is used, the finger is pressed on the end of the switch pressing block 100, the switch pressing block 100 can drive one of the contact blocks 101 to move down, the contact block 101 moves down to make the two slide rods 200 move oppositely through the extension block 401 and the connecting rod 400, the two slide rods 200 move oppositely to indirectly make the two top rods 300 move down at the same time, so that the limiting effect of the pull rod can be cancelled, and then the pull rod can be pulled to move up and down on the luggage.

[0036] As shown in Figure 1 , 2 , 6, 7,

[0037] One of the slide rods 200 and the extension block 401 on the other slide rod 200 have a V-shaped structure, the inside of the storage groove can be composed of two symmetrical inclined surfaces or arc surfaces, the storage groove is vertically aligned with the lower end of the abutting block 101, the opening width of the storage groove is greater than the width of the lower end of the abutting block 101, that is, when the abutting block 101 moves downward, the end of the abutting block 101 can move into the storage groove and then abut against the two inner walls of the storage groove, so that the slide rod 200 and the extension block 401 on the other slide rod 200 move synchronously in opposite directions, thereby indirectly making the two slide rods 200 move synchronously in opposite directions.

[0038] As shown in Figure 1 , 2 , 6, 7,

[0039] The inner end surface of each of the two slide rods 200 is provided with a second inclined surface 203, and the outer end surface of the extension block 401 on each slide rod 200 is provided with a third inclined surface 402, that is, during the downward movement of the abutting block 101, the bottom of the abutting block 101 can abut against the second inclined surface 203 and the third inclined surface 402 to make the two slide rods 200 move synchronously in opposite directions. Meanwhile, the bottom of the abutting block 101 can be provided with an arc surface, a square, a V-shaped structure, or a trapezoidal structure, that is, when the abutting block 101 moves downward, the slide rod 200 and the extension block 401 on the other slide rod 200 can move synchronously in opposite directions.

[0040] As shown in Figure 1 , 2 , 6, 7,

[0041] The bottom end of the abutting block 101 is symmetrically provided with a first inclined surface 102, and during the downward movement of the abutting block 101, the two first inclined surfaces 102 can abut against the second inclined surface 203 and the third inclined surface 402, respectively. That is, in this embodiment, the abutting block 101 is provided with a V-shaped or trapezoidal structure, and during the downward movement of the abutting block 101, the first inclined surface 102 can move in close contact with the second inclined surface 203 or the third inclined surface 402. In this way, the abutting block 101 can make the slide rod 200 or the extension block 401 slide more stably when it moves downward.

[0042] As shown in Figure 4 , 5 , 6, 7,

[0043] The connecting rod 400 is formed by extending forward from the side wall of the outer end of the slide rod 200, and the two connecting rods 400 are located on the side of the two abutting blocks 101, and the connecting rod 400 will not abut against the abutting block 101 when it slides. Moreover, the extension block 401 and the connecting rod 400 have an L-shaped structure, and the two groups of extension blocks 401 and the connecting rod 400 can be located on the side of the two abutting blocks 101.

[0044] As shown in Figure 6 , 8 ,

[0045] The chamber is also provided with a reset member capable of driving the slide rod 200 to reset, which is a push spring in this embodiment, one end of which is connected with the slide rod 200, and the other end of which is connected with the inner wall of the chamber, so that the reset member can drive the slide rod 200 to reset after the force on the switch pressing block 100 is removed, which can prevent the switch pressing block 100 from failing to rebound when the ejector rod 300 is used for a long time and the reset effect is poor.

[0046] As shown in Figure 1 , 3 , 8,

[0047] When the two slide rods 200 move away from each other in the chamber, they can drive the ejector rod 300 to slide downward, and when the two slide rods 200 move relative to each other, they can drive the ejector rod 300 to move upward. In the prior art, the end of the slide rod 200 and the end of the ejector rod 300 are usually connected by an inclined surface to achieve the movement of the two slide rods 200 away from each other, and the downward movement of the two ejector rods 300. This embodiment not only enables the slide rod 200 to drive the ejector rod 300 to move downward, but also has the effect of driving the ejector rod 300 to reset.

[0048] That is, when the spring connected with the ejector rod 300 fails to drive the ejector rod 300 to reset, the slide rod 200 can drive the ejector rod 300 to reset indirectly during the reset process.

[0051] The top of the ejector rod 300 is provided with a follower block 301, and the ejector rod 300 and the follower block 301 can move up and down together. An activity rod 302 is fixedly provided on the follower block 301, and the activity rod 302 is located in the guide groove 202 and can slide in the guide groove 202.

[0052] That is, the slide rod 200 can drive the guide plate 201 to move during the sliding process, and the guide plate 201 can drive the activity rod 302 to move up and down through the guide groove 202 during the movement, and the activity rod 302 can drive the ejector rod 300 to move up and down through the follower block 301, thereby avoiding the phenomenon that the switch pressing block 100 fails to rebound.

[0053] As Figure 1 , 3 , 8, as shown,

[0054] The movable rod 302 is in a circular structure, and the guide groove 202 is in an oblong structure, that is, the movable rod 302 can move smoothly in the guide groove 202 without being stuck.
