[0022] Please see Figure 1-4 The present invention provides the following technical solution: a lamp head connection mechanism for a multi-angle adjustable desk lamp, comprising a connection mechanism 1 and an adjustment mechanism 2, wherein the adjustment mechanism 2 is movably connected to the bottom of the connection mechanism 1.

[0023] The adjustment mechanism 2 includes a docking unit and a locking unit. The docking unit is movably connected to the bottom of the connecting mechanism 1, and the locking unit is fixedly installed on the surface of the docking unit.

[0024] The connecting mechanism 1 consists of a ball head sleeve 101, a connecting frame 102, a mounting hole 103, a locking knob 104, and an adjusting ball head 105. The connecting frame 102 is fixedly connected to the top of the ball head sleeve 101. The mounting hole 103 is opened on the surface of the connecting frame 102. The locking knob 104 is rotatably connected to the side of the ball head sleeve 101. The locking knob 104 extends into the inside of the ball head sleeve 101 and presses against the surface of the adjusting ball head 105, so that the position of the ball head 105 can be adjusted by limiting the locking knob 104. The adjusting ball head 105 is movably connected to the inside of the ball head sleeve 101, thus playing a connecting role.

[0025] The docking unit consists of an electrical connector 201, an electrical interface 202, a partition 203, an electrical connector 204, and a limiting slot 205. The electrical connector 201 is fixedly connected to the bottom of the adjusting ball head 105. The electrical interface 202 is fixedly connected to the side of the electrical connector 201. The partition 203 is fixedly connected to the surface of the electrical connector 201.
