Detailed description of the invention

Fig. 1 is the overall structure figure of the utility model.

In figure: 1, tool body；11, handle end；12, operating side；121, lumen；2, No.1 bolt；3, No. two bolts.

Specific embodiment

The utility model will be further described with reference to the accompanying drawings and examples:

Embodiment 1

It will be seen from figure 1 that a kind of air pump elastic coupling pin extracting tool of the present embodiment, including tool body 1, work Specific 1 is made of handle end 11 and operating side 12, and tool body 1 is made by 45 steel forgings and is made, and handle end 11 and 12 one of operating side are tied Structure, the inner surface of operating side 12 offer lumen 121, and the inner surface of lumen 121 is fitted with No.1 bolt 2 and No. two bolts respectively 3, No.1 bolt 2 and No. two opposition of bolt 3 are arranged, and the center of 2, No. two bolts 3 of No.1 bolt is correspondingly arranged at same horizontal line On, 2, No. two bolts 3 of No.1 bolt are threadedly coupled with operating side 12 respectively, the activity assembly respectively of 2, No. two bolts 3 of No.1 bolt In the inside of lumen 121, when operation, operating position is determined using lumen 121, by the threaded shank of No.1 bolt 2 or No. two bolts 3 Point alignment pin, turns No.1 bolt 2 or No. two bolts 3, using the working principle of screw jack, No.1 bolt 2 or No. two The strength that bolt 3 generates when extending can easily eject pin, and will not generate structural damage to pin, when operation is empty Between when being limited, disassembling sections targetedly can be carried out using No.1 bolt 2 or No. two bolts 3, extract No.1 bolt 2, i.e., The disassembling section that No. two bolts 3 carry out right-to-left can be used, conversely, extract No. two bolts 3, that is, can be used No.1 bolt 2 into The disassembling section of row from left to right.

The utility model structure is simple, small and exquisite, easy to carry, and cost of manufacture is cheap, easy to operate, securely and reliably, for Previous overhaul process improves, and significantly reduces the labor intensity of worker, improves production efficiency, has saved a large amount of people Work, time cost have better met timeliness requirement when site examining and repairing, and can also be used in other similar occasion, More for practicability.

Schematically the utility model and embodiments thereof are described above, description is not limiting, attached drawing Shown in be also one of the embodiments of the present invention, actual structure is not limited to this.So if this field Those of ordinary skill enlightened by it, without deviating from the purpose of the present invention, not inventively design Frame mode similar with the technical solution and embodiment, all should belong to the protection range of the utility model.
