[0073] In this embodiment, the outer tube 3 and the positive hook base 2 are slidably connected, which serves as a sliding guide and also avoids interference.
[0074] It should be noted that, in order to distinguish the slide rails and sliders in other positions, the slide rail here is called the first slide rail 11, and the slider here is called the first slider 12. Preferably, the first slide rail 11 is fixed on the outer tube 3, and the first slider 12 is fixed on the positive hook base 2. Of course, it is not limited to this. The first slider 12 can also be fixed on the outer tube 3, and the first slide rail 11 can be fixed on the positive hook base 2.
[0075] In one embodiment of this application, preferably, as shown below, Figure 8 As shown, the inner tube 4 and the outer tube 3 are slidably connected by a slide rail and a slider.
[0076] In this embodiment, the inner tube 4 and the outer tube 3 are slidably connected, which serves as a sliding guide and also avoids interference.
[0077] It should be noted that, in order to distinguish the slide rails and sliders in other positions, the slide rail here is called the second slide rail 13, and the slider here is called the second slider 14. Preferably, the second slide rail 13 is fixed on the outer tube 3, and the second slider 14 is fixed on the inner tube 4. Of course, it is not limited to this. The inner tube 4 can also be fixed on the outer tube 3, and the second slide rail 13 can be fixed on the inner tube 4.
[0078] In one embodiment of this application, preferably, as shown below, Figure 4 As shown, the push-type positive hook device also includes a trigger sensor 15 and a trigger component 16; wherein, the trigger component 16 is disposed on the outer tube 3, the trigger sensor 15 is disposed on the positive hook base 2, and the trigger sensor 15 and the trigger component 16 are arranged sequentially at intervals along the first preset direction, and when the outer tube 3 moves along the first preset direction toward the hook to be positive hooked to the first limit position, the trigger component 16 is used to trigger the trigger sensor 15 so that the outer tube 3 stops moving forward.
[0079] In this embodiment, when the outer tube 3 moves along the first preset direction toward the hook to be hooked to the first limit position, the triggering component 16 triggers the triggering sensor 15, thereby obtaining that the outer tube 3 has moved to the limit position, which in turn stops the drive device 1, preventing the outer tube 3 and the inner tube 4 from continuing to move forward, thus avoiding the slider from disengaging from the slide rail as described below, which would lead to structural failure. Of course, it is not limited to the above, and other layout methods can also be adopted, for example: the triggering sensor 15 is set on the outer tube 3, and the triggering component 16 is set on the hook base 2, depending on the actual needs.
[0080] Furthermore, preferably, the triggering component 16 can be an L-shaped metal part. Of course, it is not limited to this and can be designed according to actual needs.

[0082] The first limiting member 17 and the second limiting member 18 are arranged sequentially at intervals along the first preset direction. When the outer tube 3 moves along the first preset direction toward the hook to be hooked to the second limit position, the first limiting member 17 touches the second limiting member 18, so that the outer tube 3 stops moving forward.
[0083] In this embodiment, the aforementioned trigger sensor 15 and trigger member 16 serve as the first level of limiting. When the first level of limiting fails, a second level of limiting can be used. When the first level of limiting fails, the outer tube 3 and inner tube 4 will continue to move forward. When they reach the second limit position, the first limiting member 17 will contact the outer tube 3 and inner tube 4, thereby forcing them to stop moving forward. It is evident that this application provides dual limiting, making it safer and more reliable. Of course, it is not limited to this; only one limiting structure can be provided, such as only the aforementioned limiting structure of trigger sensor 15 and trigger member 16, or only the aforementioned limiting structure of first limiting member 17 and second limiting member 18.

[0088] In this embodiment, the driving device 1 drives the gear 20 to rotate, and the gear 20 drives the rack 21 to move. Since the rack 21 is fixed on the outer tube 3, it drives the outer tube 3 to move.
[0089] Of course, the transmission mechanism is not limited to the above and can be selected according to actual needs.
[0090] In one embodiment of this application, preferably, as shown below, Figure 1 As shown, the push-type positive hook device also includes a bottom support member 22, and the positive hook base 2 is fixed to the top of the bottom support member 22.
[0091] In this embodiment, a bottom support member 22 is provided at the bottom of the hook base 2, which can raise the hook base 2 to a preset working height to meet the usage requirements.
