[0054] In this embodiment, to address the inefficient bulb installation problem in related art, a bulb installation device is provided. The bulb installation device primarily comprises a housing 1, a telescopic mechanism 2, and a clamping mechanism 3. The housing 1 is hollow and accommodates the telescopic mechanism 2. The telescopic mechanism 2 can slide back and forth within the housing 1 to adjust its length. The clamping mechanism 3 is mounted on the telescopic mechanism 2 to hold the bulb.
[0055] Traditional light bulb installation methods typically require the use of tools such as ladders, requiring installers to constantly climb up and down, consuming significant time and energy. However, this device, with its telescopic mechanism 2, allows for easy length adjustment, eliminating the need for installers to frequently relocate. This allows for quick and accurate installation of light bulbs into high-placed sockets, significantly improving installation efficiency.
[0056] The clamping mechanism 3 can clamp the light bulb quickly and stably, eliminating the need for the installer to manually hold the light bulb for installation, further saving installation time.
[0057] Furthermore, one end of the guide column 9 is set on the fixing part 4, and the other end is set on the fixing part 2 6, and the lifting part 5 is set on the guide column 9; the driving part 10 is set on the fixing part 4, and the lifting part 5 is set on the output end of the driving part 10.
[0058] In this embodiment, the ends of the guide post 9 are fixed to the fixing member 1 4 and the fixing member 2 6, respectively, ensuring smooth vertical movement of the lifting member 5.

The telescopic sleeve 11 can meet the free expansion and contraction of the rubber head 12, and the elastic member 13 provides a certain pressure for the rubber head 12, so that the rubber head 12 can fit closely to the surface of the light bulb when installing the light bulb, supporting the light bulb to prevent the light bulb from shaking and accidentally being damaged, and can also provide a certain upward pushing force during the installation of the light bulb.
[0061] Furthermore, the telescopic mechanism 2 includes a rotating member 14, which is rotatably arranged on the housing 1 and has a threaded portion 15; a reciprocating member 16 is movably arranged in the housing 1, the reciprocating member 16 is hollow inside, and a thread groove 17 is provided on the inner wall of the reciprocating member 16, and the threaded portion 15 cooperates with the thread groove 17.
