So when telescopic link 123 extends to the extreme position, then screens piece 1232 under the effect of spring bar 1233, and screens piece 1232 joint is in the inside of screens groove 1231, because screens piece 1232 is provided with two sets of, the outside of cross hinge inner tube wall to reach two-way spacing effect, make telescopic link 123 through screens piece 1232 and screens groove 1231 lock, reach the effect that avoids needle 12 to be used secondarily.
Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
