New description: [New technical field] This creation is about a caster, especially a simple structure with a simple connection between the caster and the carrying device. [Prior Art] The caster system is applied to the bottom end of a carrying device such as a hospital bed, a baby carriage, a sedans car or a trolley, so that the carrying device can be moved on the ground, a caster of the prior art, as shown in the fifth figure, Attached to the bottom of the wheel frame (7D) is a wheel body (71), and the top end of the wheel frame (70) is connected with a fixed column (72) pivotable relative to the wheel frame (7〇). The fixing post (72) is coupled to the hollow tube body of the connecting tube of the carrying device. As shown in the drawing, the connecting tube has a screw hole (61) formed through the bottom end thereof, and the fixing column (72) is a Stud, the stud is coupled to the corresponding screw hole (81) of the connecting pipe (8〇), and is poured, and the fixing column (72) is opposite to the wheel frame (7) due to the steering of the carrying device. Rotating 'under long-term use' The fixing post (72) and the screw hole (81) of the connecting pipe (8〇) are combined with each other only by the thread, and the bearing device will be affected by the vibration generated during running. (72) Frequent actuation will loosen the screw hole (81) of the connecting pipe (80), thereby affecting the stability of use. Referring to FIG. 6 , another prior art caster, wherein the fixing post ( 72 8 ) at the top end of the wheel carrier ( 70A ) is a cylinder, and a screw hole (721A) is arranged in the radial direction of the cylinder body. By inserting the cylinder into the hollow tube of the connecting tube (8〇a), the tube body is provided with a perforation (δ2Α) in the radial direction, and a perforation through the wall of the connecting tube (prison) (81Α) ) and combined with the screw hole (721Α) of the pair to make the bearing device and the caster interconnected; however, the solid 3 M393438 fixed column (52A) must be accurately mastered when it is made, otherwise, if the fixed column (52A) If the outer diameter is too large, it will be difficult to pass through the connecting pipe (6〇A) and cause difficulty in assembly; if the outer diameter of the fixing post (52A) is too small, the fixing post (52a) and the connecting pipe (60A) There is a gap between the inner tube walls to cause looseness, which makes it impossible to provide a stable movement of the carrying device, and the high-precision fixing column (52 A) is accompanied by an increase in manufacturing cost and is not competitive in the market.
