The accommodating groove 13 is disposed corresponding to the damping member 30, and at least a portion of the damping member 30 is accommodated in the accommodating groove 13. That is, the number and the arrangement position of the accommodating grooves 13 are the same as those of the damper 30. Specifically, the accommodating groove 13 is disposed on the sliding seat 121. Accordingly, the damper 30 is also provided on the sliding seat 121. The plurality of dampers 30 are provided at intervals both in the circumferential direction of the sliding seat 121 and in the axial direction of the sliding seat 121. That is, the plurality of damping members 30 are divided into a plurality of groups, and each group of damping members 30 is arranged in a line at intervals in the axial direction of the sliding seat 121. The plurality of sets of damping members 30 are arranged at equal intervals along the circumferential direction of the sliding seat 121.

Both ends of the elastic member 32 abut against the bead 31 and the bottom of the receiving groove 13, respectively, so that the bead 31 abuts against the lower support rod 20. Specifically, at least a portion of the bead 31 is exposed outside the receiving groove 13 to fill a gap between the outer circumferential surface of the sliding seat 121 and the inner wall surface of the hollow cavity, so that the bead 31 is abutted against the inner wall surface of the hollow cavity by the elastic force of the elastic member 32, thereby generating a damping force in a direction opposite to the gravity direction of the upper support rod 10, so that the upper support rod 10 stays at a position desired by a user.

In the present embodiment, the elastic member 32 is a spring. Of course, the elastic member 32 may be of other elastic structures, which can be selected according to actual requirements.

As shown in fig. 1, the lower support rod 20 includes a second link 21 and a stopper 22. The second link 21 has the hollow cavity described above. The limiting member 22 is fixedly accommodated in the hollow cavity and located at the top end of the second connecting rod 21. Specifically, the shape of the outer peripheral surface of the limiting member 22 is matched with the shape of the inner wall surface of the hollow cavity, that is, the limiting member 22 is nested in the hollow cavity.

In the present embodiment, the limiting member 22 has a central through hole. The bottom end of the first link 11 passes through the central through hole to be detachably connected with the connection section 122. The outer diameter of the connection section 122 is smaller than that of the sliding seat 121 to form a docking step where the connection section 122 is connected to the sliding seat 121, and the first link 11 is connected to the connection section 122. Specifically, the shape of the inner wall surface of the central through hole is adapted to the shape of the outer peripheral surface of the first link 11. Thus, the position-limiting member 22 is nested on the first connecting rod 11, and the bottom end of the first connecting rod 11 passes through the central through hole of the position-limiting member 22 to be connected with the butt-joint step formed by the connecting section 122, and then slides in the hollow cavity under the driving of the sliding seat 121. It can be understood that, after the first link 11 enters the hollow cavity, a gap exists between the first link 11 and the hollow cavity, that is, in the hollow cavity, only the sliding seat 121 is in rolling contact with the inner wall surface of the hollow cavity through the ball 123, and the damping effect is achieved through the abutment of the glass bead 31 and the inner wall surface of the hollow cavity, and the first link 11 is not in contact with the inner wall surface of the hollow cavity. By providing the stopper 22, the first link 11 can be guided, so that the upper support rod 10 can move linearly. In addition, the limiting member 22 can also form a limiting stop for the sliding seat 121, so as to prevent the sliding seat 121 from coming out of the hollow cavity, thereby ensuring normal use of the lighting device in this embodiment.

In this embodiment, one end of the sliding member 12 is connected to the bottom end of the first link 11 by a snap-fit connection. That is, the connecting section 122 is engaged with the bottom end of the first link 11.

It should be noted that, when the upper support rod 10 is nested with the lower support rod 20, the lighting device in this embodiment is at the highest height. That is, the initial position of the lighting device in the present embodiment is the highest height position of the base. When the user needs to longitudinally adjust the light source position, the user only needs to press the upper support rod 10 downward.
