One end of the second connecting arm 500 extends into the mounting seat 100 from the right side of the mounting seat 100 to be fixedly connected with the second transmission shaft 300. The shapes of the first connecting arm 400 and the second connecting arm 500 are not limited, and in practical use, one of the first connecting arm 400 and the second connecting arm 500 is used for connecting a lamp cap, and the other is connectable to a lamp base of the desk lamp. One of the first connecting arm 400 and the second connecting arm 500 is shifted, and the other can be driven to move relatively synchronously through the linkage of the first transmission shaft 200 and the second transmission shaft 300, namely, the first connecting arm 400 and the second connecting arm 500 move relatively close or relatively far away, so that the lamp holder swings up and down rapidly relative to the lamp holder, and the lamp holder is opened or closed. The table lamp linkage structure has the advantages of simple overall structure, capability of keeping the consistency of the torsion of the first transmission shaft 200 and the second transmission shaft 300, good stability, convenient use and labor saving in the operation process.
In some embodiments of the present utility model, as shown in fig. 2 and 3, a first worm wheel 210 is provided on a first transmission shaft 200, and a second worm wheel 310 is provided on a second transmission shaft 300. The first worm wheel 210 and the second worm wheel 310 may be integrally formed on the first transmission shaft 200 and the second transmission shaft 300, respectively, or may be mounted by a socket-joint fixing method. A worm 600 is provided between the first worm wheel 210 and the second worm wheel 310. The axial directions of the first worm wheel 210 and the second worm wheel 310 are perpendicular to the axial direction of the worm 600. The first worm wheel 210 and the second worm wheel 310 are engaged with the worm 600, respectively. The first worm wheel 210, the second worm wheel 310 and the worm 600 constitute the worm wheel and worm structure described above.

In some embodiments of the present utility model, as shown in fig. 2 and 3, a first bracket 110 and a second bracket 120 are provided within the mount 100. One or both of the first bracket 110 and the second bracket 120 may be fixed to the mounting seat 100 by means of screws or the like, and the first bracket 110 and the second bracket 120 are distributed in the mounting seat 100 front and back. The two ends of the first transmission shaft 200 are respectively connected to the first bracket 110 and the second bracket 120 in a forward and backward rotation manner, and the two ends of the second transmission shaft 300 are respectively connected to the first bracket 110 and the second bracket 120 in a forward and backward rotation manner. Mounting holes can be formed in the first bracket 110 and the second bracket 120, the end parts of the first transmission shaft 200 and the second transmission shaft 300 are correspondingly inserted into the mounting holes, and then front and back locking and limiting are performed through screws or other fasteners. The first and second driving shafts 200 and 300 rotate on the first and second brackets 110 and 120. Wherein, the damping member 700 is installed at a connection position of one or both ends of the first transmission shaft 200 and the first bracket 110 and/or the second bracket 120, and/or the damping member is installed at a connection position of one or both ends of the second transmission shaft 300 and the first bracket 110 and/or the second bracket 120. The damping member 700 serves to increase rotational resistance when the first and second driving shafts 200 and 300 are rotated. As long as damping is applied to one of the first and second driving shafts 200 and 300, the linkage resistance between the first and second driving shafts 200 and 300 can be increased, thereby ensuring that the first and second connection arms 400 and 500 are positioned at the current positions. By selecting the damping strength of the damping member 700, the torque force of the first transmission shaft 200 and the second transmission shaft 300 can be quickly adjusted. Specifically, the damping member 700 may be, but is not limited to, a rubber gasket, a metal wave gasket, an arc gasket, or the like.

In some embodiments of the present utility model, as shown in fig. 3, a first extension 111 extends rearward from the first bracket 110 and a second extension 121 extends forward from the second bracket 120. The worm 600 is located between the first extension 111 and the second extension 121, and both ends of the worm 600 are rotatably connected between the first extension 111 and the second extension 121, respectively. Alternatively, as shown in fig. 4, a chute 130 is formed in the inner wall of the mount 100, and the chute 130 extends in the front-rear direction. The first bracket 110 and/or the second bracket 120 are provided with a sliding contact portion 150, and the sliding contact portion 150 may have a plate-like or block-like structure extending in the front-rear direction. During installation, the first bracket 110 and/or the second bracket 120 are slidably inserted into the sliding groove 130 through the sliding connection part 150 for guiding installation, and then the first bracket 110 and/or the second bracket 120 are fixed in the installation seat 100 through screws. The upper and lower inner walls of the installation seat 100 are provided with sliding grooves 130, two ends of the worm 600 are rotatably connected with the fixed seat 140, and the fixed seat 140 can be in a block structure. The fixing bases 140 at the upper end and the lower end are respectively movably installed in the sliding groove 130, the fixing bases 140 are guided and installed through the sliding groove 130, and meanwhile the sliding groove 130 is used for limiting the fixing bases 140 to rotate. According to the installation depth of the fixed group in the chute 130, to match the engagement positions of the worm wheel with the first worm 600 and the second worm 600. A limiting table may be disposed in the chute 130, and the fixing base 140 is fixed in cooperation with the sliding connection portion 150.
The connection structure of the first and second connection arms 400 and 500 and the first and second transmission shafts 200 and 300 may be various. In some embodiments of the present utility model, as shown in fig. 3, a clamping position is provided on the first transmission shaft 200 and the second transmission shaft 300, and hole sites matching the clamping position are provided on the ends of the first connection arm 400 and the second connection arm 500. The first transmission shaft 200 penetrates into the clamping position of the first connecting arm 400, and the second transmission shaft 300 penetrates into the clamping position of the second connecting arm 500, so that the first transmission shaft 200 and the first connecting arm 400 synchronously rotate around the axial direction, and the second transmission shaft 300 and the second connecting arm 500 synchronously rotate around the axial direction. Alternatively, the first connecting arm 400 and the first transmission shaft 200 are connected with each other by a key, and the second connecting arm 500 and the second transmission shaft 300 are connected with each other by a key, so that synchronous rotation is achieved.
