Abstract

The invention discloses a one-way javelin which comprises a javelin head and a base, wherein the javelin head is arranged above the base; a cavity is formed in the base; a needle valve is also arranged in the cavity; the needle valve is arranged upwards; and the base and the needle valve are connected through a spring. The one-way javelin disclosed by the invention is more labor-saving and humanized; the needle valve capable of retreating backwards is arranged in the javelin head, so that the area of the cross section inserted into earth is reduced; and the one-way javelin is suitable for various occasions.

Description

technical field [0001] The invention relates to a javelin, in particular to a one-way javelin. Background technique [0002] At present, people usually use tents for camping in the wild, and it is necessary to fix them when these tents are installed, and the common way is just to directly insert several metal sticks pulling ropes into the soil. But in the wild, where the environment is unpredictable, there will always be some strong winds and heavy rains when camping. In this case, the traditional fixing method becomes very unsafe. Contents of the invention [0003] Purpose of the invention: In order to solve the deficiencies of the prior art, the present invention provides a rooted and reinforced one-way javelin that can be used for field exploration. [0004] Technical solution: In order to realize the above-mentioned purpose of the invention, the technical solution adopted in the present invention is: [0005] A one-way javelin, comprising a gun head and a base, a cav...
