Caster with horizontal braking

A caster with horizontal braking, comprising:

• a connecting base;
• a wheel, rotatably connected to the connecting base;
• and
• a brake assembly, comprising a movable plate and a rotary plate, wherein the movable plate is slidably connected to the connecting base to cause the movable plate to move in a front-rear direction, a brake pad is arranged at an end of the movable plate, the brake pad is located on a front side of the wheel, the movable plate is further provided with a first abutting plate, a limiting portion is arranged on the first abutting plate, the rotary plate is rotatably connected to the connecting base, a second abutting plate is arranged on the rotary plate, the first abutting plate is fitted with the second abutting plate, and the rotary plate is rotatable in a first direction or a second direction, wherein:
• when the rotary plate is rotated in the first direction, the second abutting plate pushes the first abutting plate to move backward, the brake pad moves backward to abut against the wheel, and a rear end of the second abutting plate is abutted against the limiting portion;
• and
• when the rotary plate is rotated in the second direction, the second abutting plate detaches from the limiting portion, and the wheel pushes the brake pad to move forward away from the wheel.
