Problems solved by technology
During the operation of this scheme, the fasteners need to deform the lifting rod, which requires a relatively large force, which is likely to cause wear or even breakage of the fasteners. At the same time, it is necessary to slot and process threaded holes on the lifting rod with a larger diameter , increasing the processing difficulty of the product

Embodiment Construction
[0029] The fastening device for the lifting pole of the lamp and the lamp using the fastening device will be further described in detail mainly in conjunction with the accompanying drawings and specific embodiments.
[0030] Such as figure 1 and figure 2 As shown, a lamp according to an embodiment includes a first lifting rod 100 , a second lifting rod 200 , a lamp holder and a light source (not shown in the figure). Wherein, the lamp holder is fixed on the second lifting rod 200, and the light source is fixed on the lamp holder. In addition, in this embodiment, the lamp further includes a lamp lifting pole fastening device 300 and a bushing 400 sleeved on the second lifting pole. The lamp lifting rod fastening device 300 connects the first lifting rod 100 and the second lifting rod 200, and adjusts the height of the second lifting rod 200 to realize the lifting of the light source.
[0031] The first lifting rod 100 is a hollow columnar structure. The second lifting rod ...

The invention relates to a lamp lifting rod fastening device and a lamp using the same. The lamp lifting rod fastening device comprises a first fastening unit for fastening a first lifting rod and a second fastening unit for fastening a second lifting rod. The first fastening unit and the second fastening unit are designed for separately fastening the first lifting rod and the second lifting rod, the separately designed second fastening unit directly fastens the second lifting rod without grooving in the first lifting rod or processing a thread hole in the first lifting rod or fastening the second lifting rod through first lifting rods of other structures, so that pulling force of the handle is reduced, the function for clamping the second lifting rod can be achieved, fastening and maintaining at any height can be achieved when lifting is required, and the lamp lifting rod fastening device and the lamp using the lamp lifting rod fastening device are convenient to use and simple in structure.
Description
technical field [0001] The invention relates to the field of lighting, in particular to a fastening device for a lamp lifting rod that can lift a lamp and a lamp using the fastening device. Background technique [0002] Lifting lamps are widely used in various indoor and outdoor lighting occasions, such as industrial and mining lighting, large-scale sports facilities, cultural venues, etc., especially in some occasions where frequent maintenance of lamps is required, it can save maintenance costs and time, and ensure the safety of maintenance personnel . The lifting structure of traditional lifting lamps usually includes two lifting rods and a fastener, wherein one lifting rod has a smaller diameter and can be inserted into the other lifting rod. Fasteners are attached to the larger diameter lift rods. By slotting the elevating rod with a larger diameter, the fastening member is fastened so that the elevating rod with a larger diameter is elastically deformed at the groove...
