Description

Technical Field

[0001] This application relates to the field of teaching pole technology, and more specifically, to a multifunctional teaching pole. Background Technology

[0002] Teaching is a unique human activity that involves both the teacher's instruction and the student's learning. Through this activity, teachers purposefully, systematically, and in an organized manner guide students to learn and master cultural and scientific knowledge and skills, promote the improvement of students' overall quality, and enable them to become the people needed by society. In the teaching process, teachers use various teaching aids, among which the teaching rod is one.

[0003] In the educational process, teachers write a lot of blackboard notes. To make it easier for students to read the notes, a teaching stick is usually provided to point out the key points. However, the existing teaching sticks have a relatively simple function, only pointing to the blackboard notes. When using a projector screen, their use is limited.

[0004] Therefore, a multifunctional teaching stick is provided. Utility Model Content

[0030] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Reference Figure 1-5 A multifunctional teaching stick 100 includes: an outer rod 101, an inner rod 102, a first sliding plate 103, a laser pointer 104, a limiting block 105, a locking block 106, and a push plate 107. The inner rod 102 is vertically slidably connected to the outer rod 101. Specifically, the outer rod 101 includes a guide hole 101a, and part of the inner rod 102 is located within the guide hole 101a and moves axially along the guide hole 101a. The first sliding plate 103 is vertically slidably connected to the outer rod 101.

[0032] The outer rod 101 has a first groove 101b extending along the axial direction of the outer rod 101, and the first slide plate 103 moves along the first groove 101b. The laser pointer 104 is fixedly connected to the first slide plate 103. The limiting block 105 is engaged with the outer rod 101. The locking block 106 is fixedly connected to the limiting block 105. The push block is fixedly connected to the limiting block 105. Multiple locking blocks 106 are provided, and the multiple locking blocks 106 are equidistantly distributed along the circumference of the limiting block 105.

[0033] The limiting block 105 has a locking block 106 on its circumference, which engages with the outer rod 101. Specifically, the outer rod 101 includes a slot 101c, which engages with the locking block 106, and the slot 101c communicates with a first sliding groove 101b. The first sliding groove 101b allows the locking block 106 to be inserted. The outer rod 101 has a first cavity, within which the laser pointer 104 is located. The outer rod 101 includes a clearance groove 101e, and the laser pointer 104 includes a button 104a, through which the button 104a passes. The limiting block 105 includes a clearance hole 105a through which the light from the laser pointer 104 passes. When it is necessary to point out the key points of the writing on the board, the inner rod 102 is removed. The inner rod 102 has a certain friction with the outer rod 101 and will not move under normal conditions; it needs external force to extend or retract. When you need to point at the projector screen, simply retract the inner lever 102 to the outer lever 101, and simultaneously use the laser pointer 104 at the other end to press the switch on the laser pointer 104 to point at the multimedia projector and highlight the key points. This makes it suitable for both blackboard writing and projector screens, offering greater versatility.

[0034] Workflow: When highlighting key points on the blackboard, simply extend the inner rod 102. The inner rod 102 and outer rod 101 have friction and will not move under normal conditions; they require external force to extend or retract. When pointing to a multimedia projector, simply retract the inner rod 102 back to the outer rod 101, and simultaneously use the laser pointer 104 at the other end to point at the multimedia projector, highlighting key points. This versatile design allows for use on both blackboards and projectors.

[0035] Meanwhile, when it is necessary to remove the laser pointer 104, push the push plate 107. The movement of the push plate 107 causes the limit block 105 to move, and the movement of the limit block 105 causes the locking block 106 to move, so that the locking block 106 moves from the locking slot 101c to the first slide groove 101b, so that the locking block 106 is removed from the first slide groove 101b, so that the laser pointer 104 is freed from the restriction of the limit block 105. Then, under the action of gravity, the laser pointer 104 can be removed. The removal of the laser pointer 104 is also very convenient, which facilitates the maintenance or replacement of the laser pointer 104.

[0036] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
