In this embodiment, the second plug block 2021, the first slot 2010, the second slot 2020, and the third slot 2011 are all dip-coated with resin adhesive and hardened to ensure that the second plug block 2021 and the slots do not have edges during plugging, so that rapid plugging is realized, and multiple times of assembly and disassembly are facilitated.

Bearing frame 4's top is equipped with the supporting part 401 that is used for supporting the dabber, spacing portion 402 is located in the supporting part 401, the below of bearing frame 4 is equipped with grafting portion 410 of inserting in second slot 2020.

Further, the bearing seat 4 includes a bearing leg 41 and a seat body 40 lapped above the bearing leg 41, and the support portion 401 is in a semi-circular arc structure and is disposed above the seat body 40; the inserting portion 410 is disposed below the bearing leg 41, and an engaging portion 411 spaced from the inserting portion 410 is disposed below the bearing leg 41.

The lower side of the supporting part 401 is sequentially fixedly connected with a supporting plate 403 and a short square tube 404, the short square tube 404 is inserted into the bearing supporting leg 41, and the cross-sectional area of the supporting plate 403 is larger than that of the inner cavity of the bearing supporting leg 41.

The limiting portion 402 has a plate structure.

In this embodiment, the base body 40 is made of PVC material or metal material to improve the structural strength of the base body 40, and ensure that the bearing seat 4 can effectively support the mandrel, with good supporting effect and high stability. The support part 401, the limiting part 402, the support plate 403 and the short square tube 404 are combined into an integral structure by welding and the like. In this embodiment, the bearing support leg 41 is a square tube structure.

The utility model discloses remove pedestal 40 and adopt PVC material or metal material, all the other materials of making paper all adopt, energy-concerving and environment-protective, simultaneously the utility model discloses overall structure intensity is high, bears and compressive capacity, but recycle, resources are saved.

The foregoing shows and describes the general principles, essential features, and advantages of the invention. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention. The scope of the invention is defined by the appended claims and equivalents thereof.
