Problems solved by technology
[0002] There are two methods commonly used to lock infusion rods: one is screw locking. The disadvantages of this method are: 1. The locking and releasing operations are cumbersome; 2. The bearing weight is relatively small; 3. There are too many screws. Improper operation will cause the rod to drop accidentally; 4. The appearance is poor, and the man-machine is not friendly enough. Second, the retractable infusion rod needs two thin-walled steel pipes to be nested, and there will be problems that the thin rod is too thin or the thick rod is too thick ; The load bearing capacity of the outer thin-walled steel pipe is greatly limited

A rapid locking and releasing device for an infusion rod comprises a supporting arm and the infusion rod. A locking sleeve is arranged at the lower portion of the left side of the supporting arm, a releasing sleeve is arranged outside the infusion rod, a spring is arranged between the middle of the releasing sleeve and the supporting arm, a limiting hole is formed in the lower portion of the releasing sleeve, a steel ball is arranged between the limiting hole and the locking sleeve, an adjusting handle is arranged at the upper portion of the releasing sleeve, and the inner walls at the two sides of the locking sleeve are conical faces. The whole device is easy and convenient to operate and larger in bearing force, larger bearing force can be borne only by additionally arranging a plurality of springs and steel balls, and the possibility of infusion rod falling is avoided.
Description
technical field [0001] The invention relates to the field of locking and fixing, in particular to a quick locking and releasing device for an infusion rod. Background technique [0002] There are two methods commonly used to lock infusion rods: one is screw locking. The disadvantages of this method are: 1. The locking and releasing operations are cumbersome; 2. The bearing weight is relatively small; 3. There are too many screws. Improper operation will cause the rod to drop accidentally; 4. The appearance is poor, and the man-machine is not friendly enough. Second, the retractable infusion rod needs two thin-walled steel pipes to be nested, and there will be problems that the thin rod is too thin or the thick rod is too thick ; The load-bearing capacity of the outer thin-walled steel pipe is greatly limited. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides a quick locking and releasing device for an infusi...
