The surface of the mosquito sticky paper 23 exposed to the outside space is coated with the mosquito sticky glue, which can effectively catch mosquitoes, and when the mosquito sticky glue needs to be replaced, the mosquito sticky paper 23 in the accommodating cavity 10 can be reversed by further pulling the mosquito sticky paper 23 to release the unused mosquito sticky paper 23, and then the mosquito sticky paper 23 can be extended and laid out along the plate surface of the lining sheet 21 again and fixed the mosquito sticky paper 23 again, so that the mosquito sticky glue can be replaced. The lining sheet 21 can be reused and the mosquito sticky glue can be quickly replaced, which is economical and environmentally friendly.

In another embodiment, referring to FIG. 3 to FIG. 5, the accommodating cavity 10 is pivotally provided with a roller 12, one end of the mosquito sticky paper 23 is coiled and fixed on the roller 12, one end of the roller 12 is pivotally connected to the inner wall of the accommodating cavity 10 and the other end is transmission-connected to an operating knob 3, the accommodating cavity 10 corresponding to the operating knob 3 is provided with a pivot hole 101, the operating knob 3 is pivotally connected in the pivot hole 101 and protrudes out of a transmission shaft 30 toward the accommodating cavity 10 to be transmission-connected with the roller 12. In this embodiment, the roller 12 is driven to rotate by the operating knob 3 to guide the mosquito sticky paper 23 to be retracted in a positive roll or released in a negative roll, which is convenient for the user to operate. In the specific implementation process, the transmission connection between the transmission shaft 30 and the roller 12 can be made by means of non-circular cross-section insertion adaptation, or by means of insertion and groove insertion fixation, to achieve relative fixation in the circumferential direction of the transmission shaft 30 and the roller 12 and thus to guarantee the synchronous rotation.
