Embodiment Construction

[0024] The solution of the present invention will be described in detail below through specific implementation methods and accompanying drawings.

[0025] An electromagnetic retractable electronic whiteboard pointer provided by the present invention, such as figure 1 As shown, it includes: a pointer head 1, a pointer rod 2, a function button 3 located on the pointer rod, and a telescopic rod 4.

[0026] There is an accommodating space 8 for accommodating the telescoping rod inside the pointer rod. The telescopic rod 4 can freely expand and contract in the accommodation space inside the pointer rod 2 by rotating or sliding. The pointer head 1 is connected with the pointer rod 2 through the telescopic rod 4.

[0027] There is a magnetic core inside the pointer head 1, and an inductance coil is wound on the magnetic core. The inductance coil on the magnetic core is connected in parallel with the capacitance inside the pointer rod to form an LC oscillation circuit (not shown in...

Abstract

The invention discloses an electromagnetic telescopic electronic whiteboard pointer, and belongs to the technical field of electric digital data processing. The electronic whiteboard pointer comprises a pointer head, a pointer rod, a function button and a telescopic rod, wherein the function button is positioned on the pointer rod. An accommodating space for accommodating the telescopic rod is formed in the pointer rod; the telescopic rod can freely stretch in the accommodating space of the pointer rod in a rotating mode or a sliding mode; and the pointer head is connected with the pointer rod through the telescopic rod. By utilizing the electronic whiteboard pointer, the length of the electronic whiteboard pointer can be appropriately increased according to needs of a user, so that when the distance between the user and an electronic whiteboard, accurate teaching instruction can also be performed, the problem that a target object can only be indicated at a short range due to the fixed length of the pointer rod is solved, the efficiency of interactive teaching is effectively improved, and the electromagnetic telescopic electronic whiteboard pointer is light and portable in structure and is easy to operate.

Description

technical field [0001] The invention belongs to the technical field of electric digital data processing, and relates to an electromagnetic retractable electronic whiteboard pointer. Background technique [0002] With the development of science and technology, the education industry gradually adopts high-tech teaching and office equipment. The electronic whiteboard gradually replaces the traditional blackboard and ordinary whiteboard. The equipment supporting the electronic whiteboard generally has a special whiteboard marker and an electronic pointer. The electronic whiteboard annotates, modifies and saves the lecture content, including: word, ppt, excel and other documents and pictures in various formats, realizes the original presentation of the classroom blackboard content, and uses the electronic pointer to give teaching instructions; students You can also use the whiteboard pen to draw, answer and interactively discuss on the electronic whiteboard, making the whole teac...
