Preferably, the upper end of the concave cavity is a tapered contact surface which is arranged in a manner of gradually reducing from bottom to top, and one end of the elastic resetting piece acts on the tapered contact surface.

As a preferred scheme, the needle file is including needle file main part and integrated into one piece connector in the needle file main part, the connector upwards extends the setting from the upper end of needle file main part, the connector sets up in the cavity, the needle file main part exposes outside the needle axle, and the other end of elasticity piece that resets acts on the connector.

Preferably, the outer diameter of the connecting body is larger than that of the needle seat main body.

As a preferable scheme, the upper end of the connecting body is provided with a contact inclined plane, and the other end of the elastic resetting piece acts on the contact inclined plane of the needle tube connecting body.

Compared with the prior art, the utility model has obvious advantages and beneficial effects, concretely speaking, according to the technical scheme, the needle shaft and the needle tube are designed into an integral type, so that no combination gap exists between the needle shaft and the needle tube, the bad hidden danger caused by the external liquid flowing into the needle tube when the product is used is avoided, the normal use of the product is ensured, the structural design is ingenious and reasonable, the service life and the stability of the product are improved, and the application range is wide;

and the arrangement of the conical contact surface and the contact inclined surface increases the contact area between the needle shaft and the needle seat, thereby increasing the stability of product conduction and having good usability.

To illustrate the structural features and functions of the present invention more clearly, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

Detailed Description

Fig. 1 to fig. 3 show specific structures of embodiments of the present invention.

A waterproof PogoPin needle comprises a needle shaft 10, a needle seat 20 and an elastic resetting piece 30; wherein:

the upper end of the needle shaft 10 is provided with a contact section, the lower end of the needle shaft 10 is integrally formed with a needle tube 11, the needle tube 11 is provided with a cavity 111 with an opening at the lower end, the needle shaft 10 is movably arranged on the needle seat 20 through the cavity 111, the elastic resetting piece 30 is arranged in the cavity 111, and two ends of the elastic resetting piece 30 respectively act on the cavity 111 and the needle seat 20; preferably, said elastic return member 30 is a spring; therefore, through the integrated design of the needle shaft and the needle tube, a combination gap does not exist between the needle shaft and the needle tube, the hidden trouble that outside liquid flows into the needle tube to cause bad products in use is avoided, the normal use of the products is ensured, the structural design is ingenious and reasonable, the service life and the stability of the products are improved, and the application range is wide;
