In this embodiment, the housing 31 forms a half-enclosure on the pivot base 51, so as to cover the pivot base 51 in a specific viewing direction, and further, to hide the pivot base 51. The circumferential direction around the pivot axis, in particular the housing 31, may then represent the thickness direction of the housing 31 everywhere; the pivot seat 51 may also be prevented from loosening by a tight fit or snap-fit arrangement after being received in the mounting slot 34.

According to the trigger piece 30 with the hidden pivot seat, the pivot seat 51 and the shell 31 are arranged in a separated mode, so that the pivot seat 51 can be independently pivoted with the connecting rod 22 of the sucker piece 20 through the pin shaft 60, and the pivot assembly has a larger assembly operation space due to the fact that the limit of a shielding object is avoided, namely the shielding effect of the shell 31 is not limited. After the pivotal assembly is completed, the pivotal seat 51 is embedded in the assembly groove on the housing 31 to complete locking, so that the housing 31 shields the pivotal seat 51, and the purpose of hiding the pivotal seat 51 behind the housing 31 is achieved. In this fitting structure, the shielding portion of the housing 31, particularly, the portion near the pivot seat 51 can shorten the distance from the pivot seat 51 in the pivot axis direction, i.e., the distance between the inner wall surface of the housing 31 and the pivot seat 51 is reduced, thereby making the size of the toggle member 30 smaller; this is also advantageous in miniaturizing the suction cup device 200 to which the toggle member 30 is applied.

Further, referring to fig. 4 and 5, in an embodiment, the bottom wall of the sink 36 is provided with a positioning protrusion 38, and the body 53 is provided with a positioning groove 54 adapted to the positioning protrusion 38. In this embodiment, the positioning protrusion 38 and the positioning groove 54 cooperate to prevent the pivot base 51 from being released. It will be appreciated that the detent projections 38 may be audible when engaged with the detent recesses 54, or at least may cause a sudden increase in resistance to pushing into the pivot seats 51, so that the fitter can perceive that they are in place.

Further, the pivot hole 52 is disposed adjacent to the housing 31, and a clearance notch 371 is disposed on a side of the guide rail 37 away from the sink 36 corresponding to the pivot hole 52. In this embodiment, the pivot hole 52 is disposed adjacent to the housing 31 to form a larger force arm, so that the corresponding rotation operation is more labor-saving; the guide rail 37 is provided with the clearance notch 371 corresponding to the pivot hole 52, so that the guide rail 37 can be prevented from obstructing the assembly of the pin 60.

Further, the sink 36 has a stopper surface 361 facing the socket 35, and the body 53 is provided with a recess 55 fitted to a junction of the stopper surface 361 and an inner wall surface of the cavity 32.
