The open end of the needle tube is circumferentially provided with a plurality of elastic sheets with elasticity. The inner sides of the elastic sheets are provided with first flanges for preventing the needle from separating from the needle tube. The first flanges are pressed against the outer wall of the needle under the action of the elastic force of the elastic sheets. The outer wall of the tail end of the needle head is provided with a second flange which can abut against the first flanges under the action of the spring.
