Furthermore, as shown in fig. 8, in this embodiment, a flexible washer 81 is further installed between the locking cover 8 and the handpiece 30, and the locking force directly acts on the flexible washer 81, so that the handpiece 30 can be prevented from being scratched while being pressed. The flexible gasket 81 may be a nylon ring, a rubber ring, a silicone ring, or the like.

Further, as shown in fig. 1 and 7, in the embodiment of the present invention, the support body 1 is further installed with an auxiliary device connecting member 9, and the auxiliary device connecting member 9 can be connected with a planting auxiliary device. Because different treatment schemes are adopted for different patients, and other auxiliary device coordination, such as end effector visual marks and the like, may be required in some operations, the auxiliary device connecting piece 9 can be installed on the supporting body 1 in order to facilitate the connection of the device and the implantation auxiliary device. Specifically, the auxiliary device connecting member 9 may be an L-shaped connecting member, two side surfaces of the second support split body 12 are respectively provided with an auxiliary device connecting member mounting hole 123, the auxiliary device connecting member 9 may be fixed to two sides of the second support split body 12 through threaded connection, a threaded connection hole is also formed in a top surface of the L-shaped connecting member, and an accessory required for an operation may be mounted thereon.

Further, in the embodiment of the present invention, a tightening wrench (not shown) is further included, one end of the tightening wrench is provided with an insertion portion that is matched with the transmission groove 511 of the motor transmission member 51, and the other end of the tightening wrench is provided with a tightening portion for bearing force. The implant hand piece is subjected to larger resistance when being screwed into the implant in the dental implant operation, so that larger torque needs to be provided. When the motor 20 can not provide enough torque, a manual tightening wrench can be inserted into the transmission groove 511 of the motor transmission part 51, and the implant can be manually screwed into the planting cavity, so that the convenience and the safety of the device are improved. Specifically, the tightening wrench may be an L-shaped wrench, a T-shaped wrench, or a triangular wrench, etc., and the tightening wrench is not limited to this embodiment as long as it can facilitate manual force application.

As can be seen from the above embodiments, the quick-change device for a mobile phone planter provided by the invention is connected with the casing of the motor 20 of the mobile phone planter through the motor mounting interface 2 at the first end of the support body 1, so that the motor transmission piece 51 at the input end of the driving shaft 5 in the support body 1 can be in butt joint with the output end of the motor 20, and is connected with the casing of the head 30 of the mobile phone planter through the head mounting interface 3 at the second end of the support body 1, so that the head transmission piece 61 at the output end of the driven shaft 6 in the support body 1 can be in butt joint with the input end of the head 30, and the motion and power provided by the motor end are transmitted to the head end by using the transmission connection between the driving shaft 5 and the driven shaft 6; in addition, the third end of the support body 1 is connected with a terminal flange of the surgical robot through the robot connecting piece 4, stable structural support is provided through the support body 1, and the connection rigidity between the surgical robot and the motor 20 and the handpiece 30 of the implant handset can be improved. The device for quickly replacing the implant handpiece can quickly replace the motor 20 and the handpiece 30 of the implant handpiece respectively, improves the interchangeability and the usability of equipment, shortens the cantilever length of the implant handpiece and improves the rigidity of the whole structure, thereby improving the precision of the surgical robot in the dental operation by using the implant handpiece.

Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention, but not to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; and such modifications or substitutions do not depart from the spirit and scope of the corresponding technical solutions of the embodiments of the present invention.
