Preferably, a bracelet is fixedly arranged on the other side of the injection tube, and the injection tube is designed by adopting medical transparent plastic materials.

Preferably, the center of the bottom end of the positioning plug is provided with a hole and is communicated with the injection cylinder, the outer side of the positioning plug is provided with preformed holes in an annular array, and the positioning plug is made of medical soft rubber materials.

Preferably, the connecting seat is installed at the communicating pipe top intercommunication, and the connecting seat top is equipped with the internal thread, and stock tank bottom screw thread installs at the connecting seat top.

Preferably, a push rod is fixedly arranged at the center of the top of the sealing plug, and a connecting cover is fixedly arranged at the top of the push rod.

Preferably, the connecting cover adopts an I-shaped structural design, and the diameter of the top of the connecting cover is smaller than that of the top of the connecting cover.

Compared with the prior art, the utility model has the following beneficial effects:

according to the utility model, the injection cylinder is arranged, the communicating pipe is communicated with the injection cylinder, and then the connecting cover is pulled when in use, so that the filler falls into the injection cylinder from the storage tank through the communicating pipe, and when the connecting cover is pushed, the filler is extruded, so that the effect that the filler is not leaked in the use process is achieved.
