the syringe needle cover outside is located the syringe needle position and sets up the spout, set up slidable slider in the spout, the slider inboard is located the coupling both sides and is provided with the lantern ring and arch respectively, the lantern ring cover is established outside the syringe needle and can relative slip with the syringe needle within a definite time, and the tip position that is located the spout in the syringe needle cover sets up the inclined plane structure, and the silica gel hose is located inclined plane structure one side.
As a further aspect of the present invention: one end of the silica gel hose is connected to the multi-way pipe, and the multi-way pipe is arranged on the needle head sleeve and communicated with the connector.
As a further aspect of the present invention: the bevel structure is a bevel which is inclined relative to the axis of the needle.
As a further aspect of the present invention: the two sides of the sliding block are arranged in the sliding rail in a sliding mode.
As a further aspect of the present invention: a bolt penetrating through the sliding rail on one side is arranged in the sliding block, and a locking nut is arranged on the bolt.
Compared with the prior art, the beneficial effects of the utility model are that: when the utility model is used, when a certain needle head is needed for injection, the needle head is pushed out by the pushing slide block to be used as an anesthetic needle for injection, and the needle head pushes and pulls the silica gel hose to extend; after the needle is used up, the slider is pushed to return the needle, when the slider moves to the end part of the sliding groove, the protrusion on the slider is close to the inclined surface structure, the silica gel hose is compressed until the pipeline of the silica gel hose is closed, so that the needle can not discharge liquid when being injected, namely, the needle can discharge liquid when being pushed out for use, and is closed after returning without extra operation, so that the operation is simpler and more time-saving, and the effect of not repeatedly replacing the needle in the anesthesia process is realized.
