The hinge shaft 19 includes a first segment 1901 and a second segment 1902, the rotating frame 16 is hinged on the second segment 1902, and the bracket body 2 is fixedly connected to the rotating frame 16;

An axle seat 17 with a hollow cavity is installed on the top surface of the base 8. The axle seat 17 is rotationally connected to the first segment 1901, and the first segment 1901 is located in the hollow cavity. , a pressure column 20 with an inner cavity structure is slidably connected in the hollow cavity, and the pressure column 20 is rotatably connected to the first segment 1901. The outer wall of the pressure column 20 is provided with a pressure column along the pressure column 20. The axially extending chute 2001 of the column 20 is provided with a guide block 1701 matching the chute 2001 on the inner wall of the hollow cavity. The guide block 1701 is slidably connected to the chute 2001, so When the axis seat 17 is driven to rotate relative to the first segment 1901, the pressure column 20 and the axis seat 17 rotate synchronously;

The first segment 1901 is covered with a first spring 22. The first end of the first spring 22 is fixedly connected to the shoulder 19011 of the first segment. The second end of the first spring 22 is connected to the shoulder 19011 of the first segment.

The inner wall of the pressure column 20 is provided with a clamping block 2002 that matches the gear slot 2101;

When the first spring 22 is not compressed, the blocking block 2002 is locked into the gear slot 2101 to limit the rotation of the pressure column 20 and the shaft seat 17 relative to the first segment 1901 ;

When the pressure column 20 is pressed and moves along the first segment 1901 to compress the first spring 22, the blocking block 2002 is separated from the gear slot 2101.

It should be noted that when the operator does not press the pressure column 20, the blocking block 2002 on the pressure column 20 is stuck in the gear slot 2101 on the blocking piece 21. At this time, the pressure column 20 and the shaft seat 17 are both It cannot rotate relative to the first section 1901. If the base 8 needs to be folded, the operator can press the pressure column 20 so that the pressure column 20 moves along the first section 1901 to compress the first spring 22. At this time, the block 2002 on the pressure column 20 is separated from the gear slot 2101, and the pressure column 20 and the shaft seat 17 can rotate relative to the first segment 1901. After the operator controls the shaft seat 17 to rotate to a suitable folding angle, the pressure column 20 is subject to the reverse force of the first spring 22, and the block 2002 on the pressure column 20 automatically snaps into the gear slot 2101 corresponding to the folding angle to limit the pressure column 20 and the shaft seat 17 relative to the first The segment 1901 is rotated. Through the above design, the operator can fold the base 8 in advance before packaging and shipping. The folded base 8 becomes a plane-like structure to reduce the packaging occupied by the base 8. The space of the box allows the operator to use a smaller packaging box to pack the base 8, further reducing transportation costs.

Further, it also includes a bayonet 23 and a second spring 24;

A mounting hole 801 is provided on the bottom surface of the base 8 at a position corresponding to the axle seat 17, and a passage communicating with the hollow cavity is provided at a position corresponding to the axle seat 17 and the mounting hole 801. Hole 1702, the axis of the through hole 1702 coincides with the axis of the mounting hole 801, the axis of the through hole 1702 is perpendicular to the first segment 1901, the axis of the through hole 1702 is at the pressure On the moving trajectory of column 20;

The bayonet 23 is inserted into the through hole 1702 through the mounting hole 801. The second spring 24 is located in the through hole 1702 and is wound around the bayonet 23. The bayonet 23 is A pin shoulder 2301 is provided, the first end of the second spring 24 is in contact with the hole wall 17021 of the through hole 1702, and the second end of the second spring 24 is in contact with the pin shoulder 2301;

When the second spring 24 is not compressed, the bottom end of the bayonet 23 is exposed outside the mounting hole 801;

When the bottom end of the bayonet 23 is forced to move into the through hole 1702 to compress the second spring 24, the top end of the bayonet 23 passes through the through hole 1702 and is located in the hollow cavity to block the pressure. The column 20 moves in the direction of the second segment 1902 .

It should be noted that the above design can prevent the operator from misoperation. Specifically, when the body of the base 8 is placed flat on the table, at this time, the bottom end of the bayonet 23 is subjected to the upward force of the table. At this time, the locking The pin 23 is forced to move upward in the through hole 1702. The top of the bayonet 23 overcomes the elastic force of the second spring 24 and passes through the through hole 1702, and stays in the hollow cavity. Specifically, the top of the bayonet 23 stays on the pressure column. 20 is moving under pressure. At this time, no matter how the pressure column 20 is pressed, the pressure column 20 will not compress the first spring 22, and the blocking block 2002 on the pressure column 20 cannot escape from the gear slot 2101. The above design prevents the user from accidentally operating the pressure column 20 to cause the entire base 8 to rotate when using the base 8 normally, thereby causing the display to fall. If the main body of the base 8 is away from the desktop, under the elastic force of the second spring 24, the bayonet 23 moves downward in the through hole 1702, and the bottom end of the bayonet 23 is exposed at the bottom surface of the main body of the base 8.

Further, it also includes a button cover 18, and the side of the pressure pillar 20 away from the first spring 22 is fixedly connected to the button cover 18;

When the first spring 22 is not compressed, the button cover 18 is flush with the side of the shaft seat 17 away from the second section 1902 .

It should be noted that through the above design, it is more convenient for users or operators to press the pressure column 20 .
