Abstract:
1. A lift adjusting module adopted for use on a lamp seat of a surgical operation lamp to control the projection scope of the surgical operation lamp, comprising: a rotary shaft coupled to one side of the lamp seat; a rotary member coupled to said rotary shaft and having a plurality of cavities; at least one latch element housed in the cavities and pressed by the compression force of an elastic element being exposed outside the rotary member in normal conditions; a brake piece located on one side of the rotary shaft having a plurality of anchor holes; and a handle fastened to the rotary member for receiving external forces; wherein the brake piece is connected to the rotary member and the rotary shaft, the rotary shaft being driven by the rotary member through latching of the latching element in the anchor holes such that when handle is turned by a force the rotary shaft is turned to allow the lamp seat to generate an axial movement in a range of an upper dead point and a lower dead point, the latch element being compressed by the brake piece to sink into the cavities of the rotary member to prevent the rotary member from driving the rotary shaft thereby to avoid the surgical operation lamp from wearing and damaging under continuous presence of the force.
