In view of the above, the present invention provides an orthodontic implant nail implanting tool to solve the technical problem that the implant nail is easy to fall off when the implant nail is screwed on the alveolar bone.

The utility model discloses an orthodontic planting nail implanting tool, it includes the handle, the connecting rod that is connected with the handle, set up at the joint sleeve of connecting rod tip and with the pipe box of joint sleeve butt joint, the first half section hole of pipe box is regular hexagon hole, the latter half section hole of pipe box is the cylinder hole, is provided with the rectangle draw-in groove on the latter half section of pipe box, is provided with the screw thread on the latter half section outer cylinder face of pipe box, be provided with the latch with rectangle draw-in groove complex on the pipe box on the joint sleeve;

the planting nail tool also comprises an outer ring sleeve which is sleeved on the joint sleeve and is in running fit with the joint sleeve, and the outer ring sleeve is in threaded connection with the pipe sleeve;

the nail planting tool also comprises an elastic clamping sleeve, the elastic clamping sleeve consists of a conical opening section, a clamping neck section connected with the small end of the conical opening section and a positioning section connected with the clamping neck section, the diameter of the positioning section is larger than that of the clamping neck section, and notches which are uniformly arranged along the circumferential direction are formed in the conical opening section, the clamping neck section and the positioning section;

the tapered mouth section and the neck section are arranged in an inner hole of the upper half section of the sleeve, and a space for accommodating the elastic expansion of the tapered mouth section is reserved between the inner hole wall of the upper half section of the sleeve and the elastic clamping sleeve;

the positioning section of the elastic clamping sleeve is positioned in the joint sleeve, and a positioning counter bore matched with the positioning section is arranged in the joint sleeve.

Further, the connecting rod is a straight rod or an L-shaped rod.

The utility model has the advantages that:

the utility model discloses just abnormal planting nail implants instrument, it can connect planting nail on the sleeve pipe through elastic ferrule for planting the nail and can not dropping planting the nail when screwing up the planting nail on the alveolar bone, improved the security of screwing up the operation of planting the nail.
