Specifically, referring to fig. 4A to 4C and fig. 6, the base 10 serves as a support structure for the detachable road stud 1, and preferably, the base 10 is a solid structure, so as to stabilize the pillar 20. The base 10 may be circular or polygonal in cross-section. In this embodiment, the base 10 is preferably circular in cross-section. A groove 101 is formed in the middle of the base 10, and the groove 101 is formed by downward sinking of the upper surface of the base 10. It will be appreciated that the provision of the recess 101 at an intermediate position of the base 10 facilitates the balancing of the removable road post 1. However, in other embodiments, the position of the groove 101 may be appropriately offset from the middle position of the base 10, and is not limited herein. The cross-section of the groove 101 may be circular or polygonal. In the present embodiment, the cross section of the groove 101 is preferably polygonal, and in more detail, the cross section of the groove 101 is preferably rectangular. When the detachable road stud 1 is installed, the base 10 is buried underground such that the upper surface of the base 10 is flush with the ground. In this way, after detaching the upright post 20 separately provided thereon, it is possible to ensure smooth passing of the vehicle, prevent bumping, and avoid the base 10 from scratching the wheels. The base 10 may be formed by casting reinforced concrete or by manufacturing steel, but is not limited thereto.

Referring to fig. 7, the pillar 20 includes a root portion 201 and a baffle 202, and the baffle 202 is fixedly disposed on the root portion 201. In this embodiment, the root portion 201 and the blocking body 202 are integrally formed, and in other embodiments, the root portion 201 and the blocking body 202 may be fixedly connected by welding, bonding, or the like. Preferably, in this embodiment, the root portion 201 is configured as a solid structure, so as to enhance the strength of the root portion 201 to maintain the support of the blocking body 202 disposed thereon, and at the same time, when the pillar 20 is impacted by an external force, the root portion 201 acts as a fulcrum to interact with the base 10, and the root portion 201 is configured as a solid structure, which can effectively prevent the root portion 201 from being deformed or damaged, thereby protecting the integrity and effectiveness of the limiting mechanism 30. Preferably, in this embodiment, the blocking body 202 is a hollow structure, and by setting the blocking body 202 to be a hollow structure, not only the manufacturing cost of the detachable road post 1 can be reduced due to material saving, but also the weight of the upright post 20 can be reduced to facilitate transportation and carrying, and at the same time, the weight reduction of the upright post 20 can also reduce the stress on the base 10, prevent the base 10 from being crushed, and prolong the service life of the detachable road post 1.
