[0007] A T-shaped outer sleeve, wherein the T-shaped outer sleeve is sleeved on the outer side of the movable push rod;

[0008] The two sheaths are sleeved on both sides of the upper end of the T-shaped outer sleeve.

[0009] As an improvement, the circular baffle is located at the lower end of the T-shaped outer sleeve, the lower end diameter of the T-shaped outer sleeve matches the diameter of the circular baffle, and the upper end inner diameter of the T-shaped outer sleeve matches the diameter of the movable push rod.

[0010] As an improvement, the length of the T-shaped outer sleeve matches the length of the movable push rod.

[0011] The advantages of the utility model compared with the prior art are: when the utility model is used, the lower end of the device is inserted into the adjusted yellow mud, and the yellow mud will push the circular baffle to move upward to fill the lower end of the inner part of the T-shaped outer sleeve; as the yellow mud is continuously filled in, the movable push rod rises upward, and after the inner lower end of the T-shaped outer sleeve is filled with yellow mud, the device can be moved into the drill hole, and the D-shaped handle is pushed downward to drive the movable push rod to push the circular baffle, and all the yellow mud at the inner lower end of the T-shaped outer sleeve can be pushed out and filled to the required position. This in-hole mud injection device is easy to use, simple to operate, saves time and effort, and has high hole filling efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
