As a preferable technical scheme of the utility model, the edges and corners of the handle are arranged in an arc transition mode.

As a preferred technical solution of the present invention, the external connection component and the handle are respectively and fixedly provided with a group of anti-slip particles.

As a preferred technical scheme of the utility model, the front surface of the needle body is provided with a group of identification lines.

As a preferable technical scheme of the utility model, the outer diameter of the needle head is one point and one time of the outer diameter of the needle body at the position where the needle head is connected with the needle body.

Compared with the prior art, the utility model can achieve the following beneficial effects:

1. the hand-held handle of operating personnel is taken puncture needle whole, then pierces through the syringe needle, then pushes internal work of carrying out with the needle body according to the user demand, because of the needle body is connected with syringe needle and external connection part respectively through the threaded connection mode, can reduce the technology degree of difficulty in the production process, can dismantle when damage appears in each part in the long-term use then carry out the pertinence and change, effective resources are saved when reduce cost.

2. But anti-skidding line increases frictional force, and the hand skids when avoiding operating personnel hand to rotate to connect needle body and syringe needle, and the operation of being convenient for is used, and the needle body openly sets up a set of sign line, and operating personnel looks over the needle body directly perceived among the operation process of being convenient for and pierces the degree of depth.
