Abstract

The present invention provides a pointer for preventing forgetting. The pointer for preventing forgetting includes: a front end rod, a plurality of intermediate rods and an end rod connected in sequence; wherein, the ends of the front end rod and the plurality of intermediate rods are provided with reed buckles; There are semicircular grooves on the sides of multiple intermediate rods, and the front rods are connected to the adjacent intermediate rods through the reed buckles at the ends, and the adjacent intermediate rods are connected in turn through the reed buckles and the semicircular grooves; Wherein, the end rod is provided with a lever clip and a lever bracket, the middle part of the lever clip is hinged on the lever bracket, and one end of the lever clip can pass through the adjacent middle rod, and is stuck between the semicircular groove of the adjacent middle rod; The USB flash drive, the end rod is hollow tubular, the inner side of the end rod is provided with threads, and the tail USB flash drive is threadedly connected to the end of the end rod. The pointer for preventing forgetting can prevent the teacher from forgetting the U disk.

Description

technical field [0001] The invention belongs to the teaching field, and more specifically relates to a pointer for preventing forgetting. Background technique [0002] Pointer and U disk are the necessary teaching tools for teachers in multimedia classrooms. The pointer helps the teacher to indicate the key teaching content to all the students in the classroom, and the lecture content needs to use a USB flash drive to copy the multimedia courseware to the classroom computer to open the demonstration. Therefore, if pointer and U disk can be designed and installed as one, the portability of the two will undoubtedly be improved. [0003] Some teachers, especially university basic course teachers, need to give lectures to different classes in multiple classrooms. After the course is over, they may have to switch to another classroom to teach other classes. Computers in multimedia classrooms are generally installed under the desk, and the USB flash drive inserted on the compute...
