The lead screw 18 is rotatably connected to the support base 9. With such a setting, when disassembling the ultraviolet irradiator 4, the lead screw can be directly screwed. When the lead screw rotates, it will drive the unlocking platform 19 to move upward along the second guide rod 17. When the unlocking platform 19 abuts against and pushes the adjusting platform 13 to move, the adjusting platform 13 can be made to drive the limiting post 15 and the plug-in member 11 to move, and finally the plug-in member 11 is disengaged from the slot hole 10 to achieve unlocking and complete the disassembly.

[0047] Further, for the convenience of manually screwing the lead screw 18, the mounting assembly further includes a crank 20. The crank 20 is fixedly connected to the lead screw 18 and is used to drive the lead screw 18 to rotate.
