Description

Technical Field

[0001] The utility model belongs to the technical field of lecture note fixing devices, and in particular relates to a lecture note fixing device. Background Art

[0002] Handouts generally refer to teaching materials written by teachers for lectures. Handouts are indispensable in teachers' daily teaching process. Under normal circumstances, teachers place handouts on the podium. In the actual teaching process, in order to be able to view the contents of the handouts in real time, teachers generally hold the handouts in their hands to fix them. Although this method can fix the handouts and move them in real time, when the handouts have a lot of content and are heavy, long-term handholding can easily cause strain on the teachers' hands.

[0003] At present, the common handout fixer mainly consists of a clamping component and a liftable support frame. When in use, the handout is clamped and fixed by the clamping component, and the height of the handout is adjusted by the liftable support frame according to the actual physical condition of the teacher. For example, the Chinese utility model patent with application number: CN214904682U discloses a device for fixing ideological and political handouts, including a base and a wireless controller, a battery and a control mainboard are arranged inside the base, a charging interface is arranged at the front end of the base, a control switch, a wireless receiver and a power indicator light are arranged around the electric telescopic rod at the top of the base, a rotating seat is arranged at the top of the electric telescopic rod, a first motor is arranged on one side of the rotating plate in the rotating seat, a support column is arranged at the top of the rotating plate, a second motor is arranged at the top of the support column, a frame plate is arranged at the top of the second motor, a fill light is arranged at the top of the frame plate, notches are arranged at both ends of the front side of the frame plate, a pressing rod is arranged in the notch, a wireless transmitter is arranged at the top of the wireless controller, a touch screen is arranged at the front end of the wireless controller, the wireless controller and the control mainboard are wirelessly connected through a wireless transmitter and a wireless receiver, wireless adjustment replaces manual adjustment, greatly saves adjustment time, and improves teaching efficiency.

[0004] However, in the actual teaching process, teachers need to carry handouts and move around within a certain range, rather than fixing them on the podium. Although most handout holders in the prior art can clamp and fix handouts and adjust them at multiple angles, most of them are integrated settings and cannot be conveniently moved according to the needs of teachers, resulting in poor use effect of the handout holders.

[0005] The information disclosed in this background technology section is only intended to increase the understanding of the overall background of the present invention, and should not be regarded as acknowledging or suggesting in any form that the information constitutes the prior art already known to a person skilled in the art.

[0033] like Figure 1 to Figure 2 As shown, a torsion spring 205 is sleeved on the upper side of the fixing clip 202. The fixing clip 202 is supported and reset by the contraction and reset of the torsion spring 205, so that the handouts can be clamped and fixed by the fixing clip 202.

[0034] like Figure 1 to Figure 2 As shown, the outer side of the torsion spring 205 is sleeved with a limiting sleeve 206, which is matched with the torsion spring 205 and fixedly connected to the side wall of the fixing plate 201. The limiting sleeve 206 plays a role of contraction and limiting the torsion spring 205.

[0035] like Figures 3 to 5 As shown, the split connection assembly 3 is assembled between the fixing plate 201 and the lifting support seat 1. It is convenient to perform split connection and fixation of the lifting support seat 1 and the fixing plate 201 through the split connection assembly 3.
