[0035] Referring to Figures 1-6 A lifting switch pressing device structure comprises a connector 10 and a telescopic part 20, the telescopic part 20 is arranged to move linearly relative to the connector 10; a locking block 30 is movably arranged on the connector 10, and the locking block 30 can move from a first position to a second position relative to the connector 10; when the locking block 30 is located at the second position, the locking block 30 abuts against the telescopic part 20 to limit the linear movement of the telescopic part 20 relative to the connector 10; the connector 10 is provided with a driving assembly 40, and the driving assembly 40 is used to drive the locking block 30 to move relative to the connector 10. The locking mode adopted by the utility model is achieved by abutting and pressing, without hole matching, so that stepless locking is realized, the locking demand of different telescopic lengths is met, and the user demand is met.

[0036] When the locking block 30 is located at the first position, the locking block 30 does not abut against the telescopic part 20. So that the telescopic part 20 has a space to move relative to the connector 10, to meet the condition of telescopic adjustment.

[0037] When the locking block 30 is located at the second position, the locking block 30 abuts against the telescopic part 20 to press the telescopic part 20, so as to constrain the movement of the telescopic part 20 relative to the connector 10, and play a locking role.

[0038] Referring to Figures 2-6The driving assembly 40 comprises a knob 410 rotatably arranged on the connector 10, and the knob 410 is provided with a pushing block 420 on the end face thereof facing the locking block 30. When the pushing block 420 is in contact with the locking block 30, the pushing block 420 pushes the locking block 30 to move from the first position to the second position relative to the connector 10. In this embodiment, the knob 410 drives the pushing block 420 to move, and the pushing block 420 pushes the locking block 30 to move from the first position to the second position relative to the connector 10 in the process of moving gradually. When the locking block 30 is in the second position, the locking block 30 is in close contact with the telescopic member 20 to compress the telescopic member 20, thereby restricting the movement of the telescopic member 20 relative to the connector 10, and the locking block 30 plays a role of locking.

[0039] As shown in Figure 2 , the connector 10 is provided with a connecting cavity 120, and the knob 410 is rotatably arranged in the connecting cavity 120.
