When the push-pull member 1 is pushed to retract towards the first direction, the push-pull member 1 drives the second ejection assembly 7 to reset.

The structure and the working principle of the first triggering component 2 are similar, and are not described in detail here.

Further, as shown in fig. 3, each of the first ejection assembly 6 and the second ejection assembly 7 includes a base card 61, a card pin 62, and a tension spring 63, wherein the base card 61 is slidably connected to the first release assembly 4 or the second release assembly 5, one end of the tension spring 63 is connected to the base card 61, the other end is connected to the first release assembly 4 or the second release assembly 5, and the card pin 62 is connected between the base card 61 and the first release assembly 4 or the second release assembly 5;

before triggering, the base card 61 is clamped with the push-pull member 1, and the clamping needle 62 is clamped into the limiting groove 611 of the base card 61 to keep the base card 61 at the initial position, so that the tension spring 63 is in a stretched state;

when the first triggering component 2 is triggered, the first triggering component 2 drives the base card 61 of the second ejection component 7 to be separated from the push-pull piece 1 through the first releasing component 4, and meanwhile, the first triggering component 2 triggers the base card 61 of the first ejection component 6, so that the card needle 62 is separated from the limit groove 611 of the base card 61, the base card 61 is ejected under the action of the tension spring 63, and the base card 61 drives the push-pull piece 1 to be ejected together in the first direction;

when the second triggering component 3 is triggered, the second triggering component 3 drives the base card 61 of the first ejection component 6 to be separated from the push-pull member 1 through the second releasing component 5, and meanwhile, the second triggering component 3 triggers the base card 61 of the second ejection component 7, so that the card needle 62 is separated from the limit groove 611 of the base card 61, the base card 61 is ejected under the action of the tension spring 63, and the base card 61 drives the push-pull member 1 to be ejected together in the second direction.

Specifically, as shown in fig. 3 to 4, when the second triggering component 3 is triggered, the lifting platform 44 of the second releasing component 5 drives the first ejection component 6 to descend, so that the base card 61 is separated from the push-pull member 1, and the restriction on the second direction of the push-pull member 1 is released. Simultaneously, after the telescopic block 23 of the second trigger assembly 3 stretches out, the base card 61 of the second ejection assembly 7 is pushed, so that the card needle 62 is separated from the limiting groove 611, the base card 61 moves towards the second direction under the action of the tension spring 63, and the base card 61 drives the push-pull member 1 to pop up towards the second direction.

When pushing the push-pull member 1 to retract, the push-pull member 1 contacts with the base card 61 of the second ejection assembly 7 to drive the base card 61 to return, and the clamping needle 62 is clamped into the limiting groove 611 again, so that the tension spring 63 is stretched. The push-pull member 1 also drives the second release assembly 5, so that the first ejection assembly 6 is limited with the push-pull member 1 after being lifted.

In this embodiment, the limiting groove 611 is a Y-shaped groove, and when the ejection assembly is in the energy storage state, the clip 62 enters the limiting groove 611. When the telescopic block 23 pushes the base card 61, the card pin 62 is released from the limit groove 611 and slides along the outer edge of the Y-shaped groove. When the base card 61 is returned, the card pin 62 slides into the limit groove 611 again along the outer edge of the Y-shaped groove.

In this embodiment, the push-pull member 1 is provided with two first inclined planes 11, and the base card 61 is provided with a second inclined plane 611;

before triggering, the first inclined surface 11 is attached to the second inclined surface 611, and the base card 61 keeps the push-pull member 1 in the retracted position;

after triggering, one set of the first inclined surfaces 11 is separated from the second inclined surfaces 611, and the other set of the first inclined surfaces 11 is kept fit with the second inclined surfaces 611.

Specifically, as shown in fig. 1, before triggering, a first inclined surface 11 is respectively disposed on the left and right sides of the push-pull member 1, and a second inclined surface 611 is disposed on the two base cards 61. Wherein the second inclined surface 611 of the first ejection assembly 6 is attached to the first inclined surface 11 on the right side, so as to limit the push-pull member 1 to move towards the second direction; the second inclined surface 611 of the second ejection assembly 7 abuts the first inclined surface 11 on the left side for restricting the movement of the push-pull member 1 in the first direction.

As shown in fig. 5, when the push-pull member 1 is ejected in the second direction, the second inclined surface 611 of the second ejection assembly 7 pushes the first inclined surface 11 of the push-pull member 1. At this time, the first ejection assembly 6 descends, and the first inclined surface 11 and the second inclined surface 611 are not acted on.

When the push-pull member 1 is pushed to reset and retract, the first inclined surface 11 on the left side of the push-pull member 1 pushes the second inclined surface 611 of the second ejection assembly 7 to move towards the first direction, so as to drive the second ejection assembly 7 to reset; meanwhile, the reset block of the push-pull member 1 also drives the second release assembly 5, and the second release assembly 5 drives the first ejection assembly 6 to ascend, so that the second inclined plane 611 of the first ejection assembly 6 is just clamped with the first inclined plane 11 on the right side of the reset push-pull member 1, and the push-pull member 1 is limited again.

In this embodiment, the end of the telescopic block 23 is also provided with a slope, and when the telescopic block 23 is extended, it contacts with the second slope 611 of the base card 61 to push the base card 61.

Alternatively, other shapes of limiting structure may be provided between the push-pull member 1 and the ejection assembly, such as: the cooperation of the protrusion and the groove, or the cooperation between the serrated surface and the serrated surface, etc.

In this embodiment, as shown in fig. 6, the sliding member further includes a limiting pin 64, the limiting pin 64 is fixedly connected with the base card 61, and a clamping groove 12 is further provided on a side edge of the sliding member 1. Before the push-pull member 1 is ejected, the stopper pin 64 is engaged with the engaging groove 12, and the stopper pin 64 is used to restrict ejection of the push-pull member 1.

As shown in fig. 7, when the base card 61 ejects forward, the base card 61 drives the limit pins 64 to move forward together, the limit pins 64 slide into the slide grooves 442 of the lifting table 44 and are separated from the card slot 12, so that the limit on the push-pull member 1 is released, and the base card 61 can push the push-pull member 1 to eject outward.

In the embodiment, the push-pull member 1 is limited by two ejection assemblies before triggering, so that the push-pull member 1 is prevented from falling out to two sides. When one of the trigger components is triggered, the trigger component drives one of the ejection components to be separated from the push-pull piece through the release component, and releases the restriction on the push-pull piece, and meanwhile, the trigger component drives the other ejection component to eject the push-pull piece. In this embodiment, by triggering one of the triggering components, the push-pull member 1 can be ejected toward the corresponding direction. After the push-pull member 1 returns, the two ejection assemblies limit the push-pull member 1 at the same time, so that the push-pull member 1 is prevented from falling off from the other side when returning. According to the embodiment, a user does not need to manually pull out the push-pull piece, the effect that the push-pull piece pops up towards the corresponding side is achieved by pressing the trigger component on one side, and the operation is convenient; and the push-pull piece is pushed back and cannot be separated from the other side, so that better user experience is brought.
