DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] like Figure 1-Figure 3 As shown, a threaded pencil sharpener comprises a pencil sharpener body 1, an outer ring of the pencil sharpener body 1 is fixedly connected with a non-slip grip 2, a front end outer surface of the pencil sharpener body 1 is provided with a threaded detachable protective cover device 3 for improving safety, the threaded detachable protective cover device 3 comprises a pencil insertion ring 4 and a threaded protective cover body 7, a connecting ring 5 is fixedly connected between the pencil insertion ring 4 and the insertion hole of the pencil sharpener body 1, a connecting thread groove 6 is provided on the outer ring of the pencil insertion ring 4, a turning handle 8 is fixedly connected to one end of the threaded protective cover body 7, and a threaded debris collection device 9 is provided on the rear end outer surface of the pencil sharpener body 1 for improving the convenience of debris collection and cleaning.

[0021] The pen inserting ring 4 is fixedly connected to the front end outer surface of the pencil sharpener body 1 through the connecting ring 5, and the pen inserting ring 4 is communicated with the interior of the pencil sharpener body 1, the connecting thread groove 6 is fixedly connected to the outer ring of the pen inserting ring 4, and the turning handle 8 is fixedly connected to the front end outer surface of the threaded protective cover body 7.

[0022] The threaded protective cover body 7 is detachably connected to the pen inserting ring 4 via the connecting thread groove 6 .

[0023] The threaded debris collection device 9 comprises a connecting ring 10 and a debris collection cover 12 . The outer ring of the connecting ring 10 is provided with a fixing thread groove 11 , and the inner ring of the debris collection cover 12 is provided with a mounting thread groove 13 .

[0024] The connecting ring 10 is fixedly connected to the outer surface of the rear end of the pencil sharpener body 1, and the connecting ring 10 is communicated with the inside of the connecting ring 10, the fixed thread groove 11 is fixedly connected to the outer ring of the connecting ring 10, the mounting thread groove 13 is fixedly connected to the inner ring of the debris collecting cover 12, and the debris collecting cover 12 is detachably connected to the connecting ring 10 through the mounting thread groove 13 and the fixed thread groove 11.
