Description

Expansion flushing needle tube Technical Field The utility model relates to the technical field of flushing needle tubes, in particular to an expanded flushing needle tube. Background For cleaning skin pus cavities of large animals such as elephants, the conventional syringes used at present have obvious limitations. The diameter of the discharge hole of the common injector is smaller, and although the injection of the liquid medicine can be completed, enough flow velocity can not be formed to effectively clean necrotic tissues when the pus cavity is flushed. In addition, the outlet structure of the traditional syringe cannot be adjusted, so that the washed necrotic tissue cannot smoothly enter the syringe for extraction, the cleaning efficiency is low, and the risk of secondary pollution exists. Because of the special structure of elephant skin, the pus cavity is deeper, the necrotic tissue in the interior is difficult to remove, and repeated infection or wound deterioration is easy to cause in the cleaning process, the development of a special appliance capable of efficiently flushing the pus cavity and smoothly extracting the necrotic tissue is particularly important. Disclosure of utility model Therefore, the utility model aims to provide an expanding flushing needle tube so as to solve the problem that the size of an outlet of a traditional injector is fixed and cannot be flexibly adjusted. Based on the above object, the utility model provides an expanding flushing needle tube, which comprises a discharge hole, wherein a plurality of fixing rods are fixedly arranged on the inner wall of the discharge hole, a plurality of limiting shafts are fixedly arranged on the fixing rods, a first transmission rod is rotationally connected to the limiting shafts, the other end of the first transmission rod is rotationally connected with a fixing block through the limiting shafts, a containing groove matched with the first transmission rod for use is formed in the fixing block, a movable rod is fixedly sleeved in the middle of the fixing block, a second transmission rod is rotationally connected to the fixing block which is far away from the outlet position of the discharge hole on the movable rod, and the other end of the second transmission rod is rotationally connected with the fixing rod through the limiting shafts. Preferably, one side of the discharge hole is fixedly connected with a shell, a rubber plug is slidably arranged in the shell, and one side of the rubber plug, which is close to the discharge hole, is fixed with the movable rod. Preferably, a push-pull rod is fixedly connected to one side, far away from the discharge hole, of the rubber plug, a push-pull plate is fixedly connected to the other end of the push-pull rod, and a baffle is fixedly arranged on the outer wall of one end, close to the push-pull plate, of the shell. Preferably, the diameter value of the rubber stopper is identical to the diameter value of the inner wall of the housing. Preferably, a plurality of grooves with consistent depth are fixedly formed in the push-pull plate. Preferably, the length of the second transmission rod is longer than the length of the first transmission rod. Preferably, the discharge port is made of rubber with excellent deformation performance. Preferably, the push-pull rod is a part with two discs arranged on one side close to the rubber plug, and the main body part is in a cross shape. The utility model has the beneficial effects that: 1.
