[0032] Please refer to Figures 1 to 6 , Figure 1 A structural schematic diagram of a lamp stand provided in this embodiment, the lamp stand includes: a base 400, a first support member 100 and a second support member 200, the base 400 has a first opening 405 and a second opening 406 at both ends, the first support member 100 can be installed in the first opening 405, and is provided with a first engaging member, the second support member 200 can be installed in the second opening 406, and is provided with a second engaging member, a linkage member is provided between the first engaging member and the second engaging member, and the linkage member is engaged with the first engaging member and the second engaging member respectively.

[0033] In another embodiment, the lamp holder includes a first support member 100 and a second support member 200. The first support member 100 and the second support member 200 usually extend a connecting portion toward each other so that the support members on both sides are connected together. Common structures of the support members include but are not limited to L-shaped and T-shaped. Figure 1The L-shaped support is shown. In order to adapt to lamps of different sizes, the connection part of the first support member 100 and the second support member 200 can also be flexibly connected to facilitate adjustment of the distance between the first support member 100 and the second support member 200. Since the connection part of the first support member 100 and the second support member 200 is flexibly connected, the base 400 needs to be fixedly connected together below the connection part, and the base 400 is connected to the fixing mechanism of the lamp holder.

[0034] In this embodiment, in order to keep the first support member 100 and the second support member 200 symmetrical during installation, disassembly or adjustment, thereby keeping the center of gravity of the lamp holder on the axis of symmetry, the first engaging member is fixed to the first connecting portion 101 of the first support member 100, and the second engaging member is fixed to the second connecting portion 201 of the second support member 200, and a linkage member is arranged between the first engaging member and the first engaging member for engagement. In this way, when any support member is moved, the other support member will move synchronously in the opposite direction under the meshing action of the engaging member and the linkage member, thereby ensuring that the support members on both sides always remain symmetrical and the center of gravity of the lamp holder is maintained on the axis of symmetry.

[0035] In another embodiment, one end of the first support member 100 installed on the first opening 405 is the first connecting portion 101, and one end of the second support member 200 installed on the second opening 406 is the second connecting portion 201; the first engaging member is fixed to the first connecting portion 101, and the second engaging member is fixed to the second connecting portion 201.

[0036] See also Figure 1 , the end of the first support member 100 installed at the first opening 405 is the first connecting portion 101, the end of the second support member 200 installed at the second opening 406 is the second connecting portion 201, the first engagement member is fixed to the first connecting portion 101; the second engagement member is fixed to the second connecting portion 201. It can be understood that the first engagement member and the second engagement member are engaged with each other through a linkage member, so usually there will be overlapped portions between the first engagement member and the second engagement member, such as Figure 1 As shown, the overlapping portion of the first meshing member and the second meshing member can be a portion extending from the first connecting portion 101 and the second connecting portion 201, or can be a portion extending from the first meshing member and the second meshing member separately. At the same time, the length of the overlapping portion of the first meshing member and the second meshing member can be changed according to actual needs and is not limited here.

[0037] In another embodiment, the first connecting portion 101 is provided with a first fixing groove 103 for fixing and mounting the first gearing member, and a first accommodating groove 104 for accommodating the second gearing member, and the first accommodating groove 104 is provided with at least one first limiting member 105 for limiting the second gearing member; the second connecting portion 201 is provided with a second fixing groove 203 for fixing and mounting the second gearing member, and a second accommodating groove 204 for accommodating the first gearing member, and the second accommodating groove 204 is provided with at least one second limiting member 205 for limiting the first gearing member.
