[0013] The above technical solution facilitates the hanging and placement of the writing mechanism.

[0014] As a further improvement to this utility model, a rubber block is connected to the extrusion end of the screw.

[0015] The above technical solution utilizes the compressive deformation of the rubber block to enhance the anti-slip effect at the screw end.

[0016] As a further improvement to this utility model, the fixing mechanism also includes an adjusting frame welded to the outside of the outer frame, and the non-screw hole area of ​​the U-shaped frame is provided with a sliding cavity for sliding on the adjusting frame, and the inner wall of the sliding cavity is in close contact with the surface of the adjusting frame to form a damping friction limit.

[0017] Implementing the above technical solution facilitates changing the location of the U-shaped frame.

[0018] As a further improvement to this utility model, a notch is provided at the U-shaped frame to allow the sliding cavity to pass through, for the support leg of the adjustment frame to pass through.

[0019] The above technical solution facilitates the complete removal of the U-shaped frame from the adjustment frame.

[0020] As a further improvement to this utility model, the adjustment frame is extended and elongated and passes through at least one apex corner of the outer frame.

[0021] The above technical solution allows the U-shaped frame to move to more positions outside the outer frame.

[0022] The technical effects and advantages of this utility model are as follows: This utility model uses a screw end that can move toward the U-shaped frame cavity, and works in conjunction with the blocking at the non-screw hole of the U-shaped frame, so that the U-shaped frame can be adapted to fix extension rods of different widths.

U-shaped frame; 211. Screw; 212. Adjustment frame; 213. Sliding cavity; 214. Rubber block; Detailed Implementation The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0031] Example: Referring to the accompanying drawings, this utility model provides a music score reading board that, through its double-sided writing and adjustable fixing design, enables convenient writing, display, and position adjustment of musical scores in music teaching. Its structure is as follows: In writing institution 100: The outer frame 110 is made of aluminum alloy profiles and has a rectangular frame structure with rounded corners. The frame is hollow inside to reduce weight and enhance structural rigidity. In addition, stainless steel hanging rings 112 (with spacing matching the standard music stand crossbar) are welded to the top two sides of the outer frame 110 to hang the music reading board on the wall hooks or movable brackets. The writing board 111 is a double-sided magnetic whiteboard, the size of which matches the inner frame of the outer frame 110. It is attached to both sides of the outer frame 110 with glass glue to form a symmetrical double-sided writing area, which can be written on directly with magnetic sheet music stickers or whiteboard markers.

[0032] In fixed mechanism 200: Limiting part The U-shaped frame 210 is made of steel by stamping. The opening width is adapted to the lifting rod of the bearing rod with a diameter of 20-50mm. A sliding cavity 213 is opened on the side of the U-shaped frame 210. The inner wall of the sliding cavity is frosted and forms a damping fit with the adjusting frame 212 (to prevent self-slip). A screw hole is screwed into the side of the U-shaped frame 210, and a screw 211 is screwed into the screw hole. The pressing end of the screw 211 is attached to and fixed with a rubber block 214. The surface of the rubber block is made with anti-slip texture to enhance the friction with the support rod.

[0033] Position adjustment section The adjustment frame 212 is made of T-shaped aluminum alloy profile, and its length extends through the top corner of the outer frame 110 (covering at least 1 / 2 of the frame length of the outer frame 110). The legs of the outer frame 110 are welded to the outside of the outer frame 110. In addition, the outer frame 110 and the inner wall of the sliding cavity 213 of the U-shaped frame 210 are closely fitted to form a linear sliding track for adjusting the U-shaped frame 210. At the same time, a rectangular notch (wider than the width of the legs of the adjustment frame 212) is opened on the sliding cavity 213 of the U-shaped frame 210 for the legs of the adjustment frame 212 to pass through. The edges of the notch are rounded to avoid jamming during sliding.

[0034] The specific installation and adjustment process is as follows: Sliding adjustment: According to the installation position of the support rod (such as the lifting rod extension rod), push the U-shaped frame 210 along the adjustment frame 212 to make it slide to the target position. Due to the damping friction between the sliding cavity 213 and the adjustment frame 212, the U-shaped frame 210 can be self-limited after releasing. Inserting the support rod: With the opening of the U-shaped frame 210 facing the support rod, move the writing mechanism 100 horizontally so that the support rod is inserted into the inside of the U-shaped frame 210, while ensuring that the rubber block 214 is aligned with the surface of the support rod; Tighten and fix: Rotate the handle of the screw 211 to move the screw 211 along the screw hole axially, causing the rubber block 214 to squeeze the bearing rod until the U-shaped frame 210 is tightly attached to the bearing rod, and fixation is achieved through friction. Angle adjustment: The U-shaped frame 210 can be rotated (around the axis of the adjustment frame 212 by ±15°) after the screw 211 is loosened, and then tightened again to meet the needs of different viewing angles for spectrum reading.
