[0033] The first slide plate 4 and the first driving member are both arranged on the machine 1. The first driving member is connected to the first slide plate 4 to drive the first slide plate 4 to approach or move away from the first interface of the first quick-plug connector 3. In the initial state, the first slide plate 4 is away from the first interface of the first quick-plug connector 3. When assembly is required, the first driving component drives the first slide plate 4 to approach the first supporting platform 2 to assemble the first interface of the first quick-plug connector 3 with the first supporting platform 8. The first driving member is used to provide sufficient force to ensure that the first interface of the first quick-plug connector 3 and the first supporting platform 8 are stably assembled.

[0034] The second slide plate 5, the second driving member and the first supporting platform 8 are all arranged on the first slide plate 4, and the second supporting platform 9 is arranged on the second slide plate 5. The second driving member is connected to the second slide plate 5 to drive the second slide plate 5 to approach or move away from the first supporting platform 8. The first supporting platform 8 and the second supporting platform 9 are both used to carry multiple second quick-connect connectors 26. The structures of the first supporting platform 8 and the second supporting platform 9 are not limited here, and are based on being able to stably support the second quick-connect connector 26.
