A retractable double-head scaler for dental surgery, including a handle body, the handle body includes a first handle and a second handle, the outer walls of the opposite ends of the first handle and the second handle are formed with external threads, and the adjustment The sleeve body is screwed into the external thread of the first handle and the second handle, the left end of the first handle and the right end of the second handle are formed with a head connecting hole, and the outer wall of the end of the head connecting hole is formed with an annular groove. The permanent magnet ring is fixed on the inner wall of the annular groove. One end of the installation connection part is formed with a scraping head, and the other end of the installation connection part is formed with a mounting rod. The installation rod is inserted into the corresponding head connection hole. Set in the permanent magnet ring and adsorb with the permanent magnet ring;

There are multiple radial screw through holes formed on the mounting rod, the double-headed ball plunger is screwed into the radial screw through hole, and the two balls of the double-headed ball plunger are nested inside the head connection hole In the concave hole formed on the wall.

A non-slip elastic sleeve is fixed on the outer wall of the adjustment sleeve body.

The left end of the first handle and the right end of the second handle are both formed with annular grooves, the elastic sealing ring is nested in the annular groove, and the end surface of the installation connecting part with the installation rod is pressed against the elastic sealing ring.

The installation connection part is a conical block.

A scraping head is formed at the end of the small-diameter end of the installation connection part, and a mounting rod is formed at the middle of the end part of the large-diameter end of the installation connection part.

An annular adjusting ring is formed on the outer wall of the middle part of the adjusting sleeve.

The outstanding effect of the present invention is: compared with the prior art, it adopts the first handle and the second handle to form a handle body, which can be used singly or connected, and has a detachable installation connection part, and the installation connection part It is directly formed with a scraping head, so that the installation connection part can be replaced directly after one use without replacing the handle body, which saves environmental protection and improves the use time of the handle. Any of them can adjust the length of the handle body to meet the length requirements of different operators.
