After drug injection is finished with the safe syringe, the needle can be bent in the needle cylinder, so that secondary recovery is avoided and staff infection caused by stabbing or scratching of the needle is avoided during syringe collection.

The invention discloses an arc isolation structure of a contactor. The arc isolation structure comprises a first shell which is used for installing auxiliary static contacts, a second shell which used for installing primary static contacts and multiple arc isolation plates. The opening of the first shell is downward. The second shell is accommodated in the first shell. The middle segment of the second shell is provided with a moving contact component. The second shell is provided with multiple chambers of which the openings face the moving contact component so as to providing matching of primary moving and static contact points in the chambers. The arc isolation plates are inserted in the corresponding chambers of the second shell from the openings of the chambers along a horizontal direction and form isolation of the side walls of the chambers. When the second shell is matched with the first shell, the second shell presses the arc isolation plates in a clamping way from above so that the arc isolation plates are enabled not to withdraw out of the chambers from the openings of the chambers along the horizontal direction. The arc isolation structure of the contactor has the characteristics of being simple in structure, low in cost and easy to assemble and especially reduces the assembling difficulty.
