[0008] Preferably, the outer wall of the mounting head and the inner wall of the mounting groove are plugged into each other, and electrically connected contacts are installed on the inner wall of the mounting head of the contra-angle handpiece and the inner wall of the main unit mounting groove.

[0009] Preferably, multiple groups of the limiting members are axially symmetrically fixed on the inner side wall of the installation groove, and two limiting members in the same group are symmetrically installed on the two ends of the elastic clamping member, and the upper and lower surfaces of the limiting members are provided with penetrating sliding grooves.

[0010] Preferably, the side walls at both ends of the elastic clip are slidably connected to the inner wall of the slide groove, the notch is a chamfered ring groove, the outer wall of the notch and the outer wall of the elastic clip abut and slide, the cross-section of the positioning ring groove is triangular, the outer wall of the positioning ring groove and the protruding end of the elastic clip are clamped, and the elastic clip is installed with a sponge pad near the outer wall of the positioning ring groove.

[0011] By adopting the above technical solution, when the product is in use, the equipment is kept stopped, and the mounting head at the lower end of the bending machine head is aligned with the mounting slot in the main unit and inserted downward for installation. During the sliding installation process, the protruding end of the elastic clip is squeezed toward the inside of the mounting slot for storage, and at the same time, its two ends slide toward the inner walls of the limit members on both sides until the missing slot is separated from the protruding end of the elastic clip and contacts and slides with the side walls of the mounting head. The mounting head is continued to be moved downward to keep the protruding end and the positioning ring groove parallel. At this time, the protruding end of the compressed elastic clip is restored so that its protrusion abuts against the positioning ring groove, and they cooperate with each other to fix the height of the entire main unit. At the same time, the outer wall of the positioning ring groove and the elastic clip can be rotated, so that the bending machine head on the main unit can be quickly disassembled and assembled.

[0013] Preferably, an upper fixing groove is provided at the bottom end of the positioning seat, the upper fixing groove is an annular groove, and an iron ring is installed on the inner wall of the upper fixing groove.

[0014] Preferably, the magnet ring and the iron ring are magnetically connected, and the magnetic strength of the magnet ring does not hinder the rotation between the magnet ring and the iron ring.

[0015] By adopting the above technical solution, after the contralateral handpiece is installed, in order to prevent the contralateral handpiece from falling off after installation, during the installation process, the magnet ring in the main unit positioning groove and the iron ring on the contralateral handpiece positioning seat are adsorbed to ensure that the connection between the main unit and the contralateral handpiece is stable while not hindering the rotation of the contralateral handpiece, thereby improving the strength of the installation and avoiding the contralateral handpiece from falling off due to excessive force when swinging the main unit, thereby ensuring safety in use.

[0016] The beneficial effects of the utility model are:

[0017] The multiple sets of limiters installed on the inner wall of the mounting groove at the upper end of one end of the main machine cooperate with the elastic card machine to effectively limit the deformation direction of the elastic card. At the same time, the notch and positioning ring groove opened at the bottom end of the positioning seat at the lower end of the bending machine head cooperate with the deformable elastic card during the downward movement, and support them when the elastic card and the positioning ring groove are parallel, and cooperate with each other to fix the height of the entire main machine. At the same time, the outer wall of the positioning ring groove and the elastic card can be rotated, so that the bending machine head on the main machine can be quickly disassembled and assembled, making the installation and carrying of the entire equipment more convenient. The sponge pad arranged on the outer surface of the elastic card increases the friction between the elastic card and the positioning ring groove, so that the main machine will have a sense of obstruction during the rotation process, ensuring the stability effect after angle adjustment, and the set magnet ring cooperates with the iron ring to improve the stability after installation, and avoid loosening and causing the bending machine head to fall off.
