Because in the general endodontic machine handle 100, the turntable 1 and the turntable base 2 are both made of metal, in the process of rotating the turntable 1 relative to the turntable base 2, some obstinate and laborious use experience is inevitably existed, and the contact portion between the turntable 1 and the turntable base 2 is easy to wear in different degrees after a period of use, as shown in fig. 2, 4 and 5, in this embodiment, the endodontic machine handle 100 further includes a connecting ring 4, the boss 11 is provided with a seventh ring groove 111 along the radial direction, a second accommodating cavity is formed in the seventh ring groove 111, and the connecting ring 4 is accommodated in the second accommodating cavity, so that the rotation between the turntable 1 and the turntable base 2 is easier by adding the connecting ring 4. Alternatively, the material of the connecting ring 4 may be a flexible material with abrasion resistance such as a rubber material. The number of the connection rings 4 is not particularly limited, and may be one or more.
In this embodiment, the turntable base 2 is disposed in the housing 3, and the connection between the turntable base 2 and the housing 3 may be a threaded connection, specifically, a first thread 26 is disposed on an outer wall surface of the turntable base 2 near the bottom of the turntable base 2, a second thread is disposed on a side wall surface of the fifth ring groove 32 corresponding to the first thread 26, and the turntable base 2 is connected in the fifth ring groove 32 through the threaded connection of the first thread 26 and the second thread.
In order to enable the dental elbow rest 600 to be locked with respect to the endodontic handpiece 100 after the practitioner rotates the dental elbow rest 600 to an optimal gripping position with respect to the endodontic handpiece 100, in this embodiment, the endodontic handpiece 100 further includes a locking assembly 5 for locking the dental elbow rest 600, one end of the locking assembly 5 is disposed in the turntable base 2, and since the first ring groove 21 is for contact with the boss 11 and the second ring groove 22 is for contact with an end of the dental elbow rest 600, one end of the locking assembly 5 is disposed in the third ring groove 23.
As shown in fig. 2, 4 and 5, the locking assembly 5 includes a motor connector 51, and a sidewall of the third ring groove 23 is used to contact with an outer wall surface of a top of the motor connector 51, so as to accommodate the motor connector 51 in the turntable base 2. The locking assembly 5 is connected with the turntable base 2 through a motor connecting piece 51, and the motor connecting piece 51 and the turntable base 2 can be connected in a threaded manner. Specifically, the outer wall surface of the motor connecting piece 51, which is close to the top of the motor connecting piece 51, is provided with a third thread 511, and the side wall surface of the third ring groove 23 is provided with a fourth thread corresponding to the third thread 511, and the motor connecting piece 51 is connected in the third ring groove 23 through the threaded connection of the third thread 511 and the fourth thread.
The locking assembly 5 further comprises a steel ball collar 52 and a steel ball 53, the steel ball collar 52 is sleeved outside the motor connecting piece 51, a through hole 512 is formed in the side wall surface of the motor connecting piece 51, a first groove 521 is formed in the inner wall surface of the steel ball collar 52 corresponding to the through hole 512, the first groove 521 and the through hole 512 are used for accommodating the steel ball 53, the steel ball 53 can rotate in the first groove 521 and the through hole 512, and parts, protruding out of the first groove 521 and the through hole 512, of the steel ball 53 are used for being in contact with the end part of the dental elbow 600.
As shown in fig. 2, 4 and 5, in the present embodiment, the dental elbow piece 600 is provided with a second groove 6 at an end portion thereof, specifically, a portion of the steel ball 53 protruding from the first groove 521 and the through hole 512 is for contact with the second groove 6.
It should be noted that, the first groove 521 and the second groove 6 are used for contacting the steel ball 53 to define a rotation range of the steel ball 53 along the radial direction, the through hole 512 is used for contacting the steel ball 53 to define a rotation range of the steel ball 53 along the installation direction of the dental elbow phone 600, and the first groove 521, the through hole 512 and the second groove 6 cooperate with each other to accommodate the steel ball 53 within the rotation range. When the doctor rotates the dental handpiece 600 to the optimal holding position relative to the endodontic handpiece handle 100, and the dental handpiece 600 needs to be locked relative to the endodontic handpiece handle 100, the steel ball 53 is pressed inwards by the steel ball collar 52, so that the steel ball 53 enters the second groove 6 at the end of the dental handpiece 600, thereby realizing the locking of the dental handpiece 600 relative to the endodontic handpiece handle 100.
In order to avoid the relative rotation between the steel ball collar 52 and the motor connector 51, so that the dental bending hand piece 600 cannot be locked relative to the handle 100 of the root canal therapy machine, in this embodiment, a protrusion 513 is further provided on the motor connector 51 along the radial direction, a notch 522 is provided on a side wall surface of the steel ball collar 52 corresponding to the protrusion 513, and the protrusion 513 is accommodated in the notch 522, so that the steel ball collar 52 cannot rotate relative to the motor connector 51, and the steel ball collar 52 can only cooperate with the through hole 512 and the second groove 6 at the end of the dental bending hand piece 600, so as to further limit the movement range of the steel ball 53 along the radial direction.
In order to make the dental bending hand piece 600 relatively stable when locked with respect to the endodontic treatment machine handle 100, and the dental bending hand piece 600 and the endodontic treatment machine handle 100 are uniformly stressed in the radial direction, in this embodiment, the steel balls 53 include two steel balls 53 symmetrically disposed on the motor connecting piece 51. Further, the two steel balls 53 may be symmetrically disposed on both sides of the protrusion 513 to avoid the influence of the position of the protrusion 513 on the forces applied to the dental bending hand piece 600 and the endodontic machine in the radial direction.
It should be noted that, in other embodiments, the number of the steel balls 53 may be one, but compared with two symmetrically arranged steel balls 53, the locking of the dental bending hand piece 600 is slightly unstable and the acting force is not uniform by one steel ball 53, but the material cost can be saved; the number of the steel balls 53 may be plural, and the plurality of steel balls 53 may be uniformly distributed on the motor connector 51 along the radial direction, but compared with two symmetrically arranged steel balls 53, the plurality of steel balls 53 are uniformly distributed along the radial direction, so that on one hand, the influence of the position of the protrusion 513 is not easy to avoid, and on the other hand, the locking and unlocking process of the dental bending hand piece 600 relative to the handle 100 of the endodontic treatment machine is more laborious, and meanwhile, the unnecessary material cost is increased.
The above description is only of the preferred embodiments of the present invention and is not intended to limit the present invention, but various modifications and variations can be made to the present invention by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
