[0035] In this embodiment, the positioning member includes a left positioning member 31 and a right positioning member 32, the clamping member includes a left clamping member 51 and a right clamping member 52, the friction member includes a left friction member 41 and a right friction member 42, the connecting member includes a left connecting member 91 and a right connecting member 92, the panel assembly has a left matching groove 21 matched with the left positioning member 31 and a right matching groove 22 matched with the right positioning member 32, the left connecting member 91 sequentially passes through the left side of the panel assembly 2, the left positioning member 31, and the left clamping member 51, and the right connecting member 92 sequentially passes through the right side of the panel assembly 2, the right positioning member 32, and the right clamping member 52.

[0037] The working principle of the display pitch adjustment assembly of the utility model is as follows:

[0038] The swivel seat 1 is connected to the panel assembly 2 by rotation around the first axis so as to switch between the upward-looking state and the downward-looking state. When switching to the upward-looking state, the panel assembly 2 is rotated clockwise by hand. Due to the matching structure between the positioning member and the panel assembly 2, the positioning member and the panel assembly 2 rotate synchronously. Due to the synchronization structure between the positioning member and the clamping member, the clamping member and the positioning member rotate synchronously. Since the outer surface 351 of the inner wall is in frictional contact with the friction member, the friction member and the positioning member rotate in the same direction. Due to the linkage structure set between the friction member and the one-way gear 6, the one-way gear 6 rotates synchronously with the friction member. The bevel gear 7 is subjected to the downward force of the one-way gear 6 and rotates counterclockwise around the second axis to avoid. The torsion spring 8 accumulates elastic force, and the torsion spring 8 rebounds to stop the one-way gear. For further clockwise rotation of the gear 6, that is, switching to the upward-looking state, the user needs to resist gravity and the elastic force of the torsion spring 8; when switching to the downward-looking state, the panel assembly 2 is rotated counterclockwise by hand, and due to the matching structure between the positioning member and the panel assembly 2, the positioning member and the panel assembly 2 rotate synchronously, and due to the synchronization structure between the positioning member and the clamping member, the clamping member and the positioning member rotate synchronously, and due to the setting of the one-way mechanism between the friction member and the rotating head seat 2, the bevel gear 7 prevents the one-way gear 6 from rotating counterclockwise, and due to the linkage structure set between the one-way gear 6 and the friction member, the friction member cannot rotate counterclockwise, that is, when switching to the downward-looking state, although gravity can be used, the user needs to resist the friction between the outer surface 351 of the inner wall and the friction member.

[0039] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model.
