DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Embodiment

[0025] Please refer to Figures 1 to 5 For the embodiments of the present application, the embodiments provide a technical solution: a cuttable base column, comprising

[0026] The base column body 1, the connecting interface 3 arranged at the top end of the base column body 1, the base tail 2 arranged at the bottom end of the base column body 1, the screw groove 11 arranged in the inside of the base column body 1 for placing and installing screws, the tail threaded hole 21 arranged in the bottom surface of the base tail 2 and communicated with the screw groove 11, and the top hole 31 arranged in the top surface of the connecting interface 3 and communicated with the screw groove 11, wherein the base column body 1, the connecting interface 3 and the base tail 2 are integrated structures;

[0027] And the detachable protective sleeve 5 arranged at the bottom surface of the base tail 2 and sealing the bottom end of the tail threaded hole 21, which can effectively protect the tail threaded hole 21 during storage and transportation, avoid the entry of foreign matters from the outside, reduce unnecessary subsequent cleaning steps, and also play a role in preventing the screws in the screw groove 11 from falling off.

[0028] In the embodiment, preferably, the top surface of the detachable protective sleeve 5 is provided with an integrated annular rubber insertion cylinder 52, and the annular rubber insertion cylinder 52 is inserted into the tail threaded hole 21.

[0029] In the embodiment, preferably, the outer wall of the annular rubber sleeve 52 is provided with a plurality of integral annular outer limiting protrusions 53, the detachable protective sleeve 5, the annular rubber sleeve 52 and the annular outer limiting protrusions 53 are all made of medical silica gel material, and will elastically deform when being pressed, and the annular outer limiting protrusions 53 are in extrusion contact with the inner wall of the tail threaded hole 21, limiting the annular rubber sleeve 52 and the detachable protective sleeve 5 through friction, so as to ensure the installation stability of the detachable protective sleeve 5 during storage and transportation.

[0030] In the embodiment, preferably, the cross section of the annular outer limiting protrusion 53 is a right triangle, so that the annular rubber sleeve 52 is easy to elastically deform when being inserted into the tail threaded hole 21, and the annular outer limiting protrusion 53 can be like a reverse buckle and abut against the inner wall of the tail threaded hole 21 after being inserted, so as to ensure the installation stability of the annular rubber sleeve 52 and the detachable protective sleeve 5.

[0031] In the embodiment, preferably, the outer surface of the detachable protective sleeve 5 is provided with an annular groove 51, which can facilitate the pulling force of the subsequent operator when removing the detachable protective sleeve 5, so as to avoid that the detachable protective sleeve 5 is too smooth on the surface and is not easy to remove.
