Please refer to Figures 1-5 , including a forceps body 100;
[0029] Please refer to again Figure 1 , Figure 2 and Figure 4, a mounting head 110 is fixedly connected to the top of the pliers body 100. The mounting head 110 is used to cooperate with the slot 111 and the mounting groove 112 to install the pliers head 114. A slot 111 is opened at the top of the mounting head 110. The slot 111 is used to install the plug 113. An installation groove 112 is opened inside the mounting head 110 and below the slot 111. The installation groove 112 is used to install the bidirectional lead screw 116 and limit the fixed block 118. The slot 111 communicates with the installation groove 112. A plug 113 is inserted into the inner cavity of the slot 111. The plug 113 is used to connect the mounting head 110 and the pliers head 114. The top of the plug 113 extends to the outside of the mounting head 110 and is fixedly connected to the pliers head 114. The inner side walls of the two pliers heads 114 are in contact with each other. The bottom of the plug 113 extends to the inner cavity of the installation groove 112. Fixing grooves 115 are opened on the left and right side walls of the plug 113 and inside the installation groove 112. The fixing grooves 115 are used to cooperate with the fixed blocks 118 to fix the plug 113. The inner cavity wall of the installation groove 112 and below the plug 113 is rotatably connected to the bidirectional lead screw 116 through a pin shaft. The bidirectional lead screw 116 is used to drive the two fixed blocks 118 to move towards each other. The end of the bidirectional lead screw 116 extends to the outside of the mounting head 110 and is fixedly connected to a knob 117. The knob 117 is used to drive the bidirectional lead screw 116 to rotate. Fixed blocks 118 are screwed on the outer side wall of the bidirectional lead screw 116 and on the left and right sides of the plug 113. The fixed blocks 118 are used to cooperate with the fixing grooves 115 to fix the plug 113. The top and bottom of the fixed block 118 are slidably connected to the inner side wall of the installation groove 112. The inner side wall of the fixed block 118 extends into the inner cavity of the fixing groove 115 and is clamped with the inner cavity wall of the fixing groove 115. A connecting block 119 is fixedly connected to the bottom of the pliers body 100. The connecting block 119 is used to install the pliers handle 120. The outer side wall of the connecting block 119 is rotatably connected to the pliers handle 120 through a pin shaft. The pliers handle 120 is used for operation. There are two pliers bodies 100. The two pliers bodies 100 are rotatably connected through a pin shaft. Auxiliary blocks 130 are fixedly connected to the left and right side walls of the plug 113 and inside the slot 111. The auxiliary blocks 130 are used to assist in fixing the plug 113 for subsequent fixing. The outer side wall of the auxiliary block 130 is clamped with the inner cavity wall of the slot 111. The outer side wall of the knob 117 is provided with anti-slip lines. The anti-slip lines are used to facilitate the rotation of the knob 117. Insert the pliers head 114 into the installation groove 112 through the plug 113 and the slot 111. The auxiliary block 130 is clamped with the slot 111 for preliminary fixing. Rotate the bidirectional lead screw 116 through the knob 117. The rotation of the bidirectional lead screw 116 drives the two fixed blocks 118 to move towards each other and then enter the fixing groove 115 and be clamped with the fixing groove 115. Thus, the pliers head 114 is installed by fixing the plug 113. When disassembly is required, just rotate the knob 117 in the reverse direction;
[0030] In summary, it is possible to conveniently replace the new jaw 114 when the jaw 114 is damaged, thus improving the practicability without replacing the new orthodontic forceps.
[0031] Please refer again to Figure 1 , Figure 2 , Figure 3 and Figure 5 , on the left side wall of the left connecting block 119 and the right side wall of the right connecting block 119, adjustment grooves 140 are formed. The adjustment grooves 140 are used to cooperate with the clamping blocks 142 to adjust the angle of the forceps handle 120, and the adjustment grooves 140 are evenly distributed in a ring shape. Inside the forceps handle 120 and outside the connecting block 119, a sliding groove 141 is formed. The sliding groove 141 is used to install the clamping block 142 and the fixing spring 143. The inner cavity wall of the sliding groove 141 is slidably connected with the clamping block 142. The clamping block 142 is used to cooperate with the adjustment groove 140 to fix the forceps handle 120. The inner cavity wall of the sliding groove 141 is fixedly connected with the fixing spring 143. The fixing spring 143 is used to reset the fixing clamping block 142. The end of the fixing spring 143 is fixedly connected with one end of the clamping block 142. The other end of the clamping block 142 extends into the inner cavity of the adjustment groove 140 and is clamped with the inner cavity wall of the adjustment groove 140. On the upper side of the left side wall of the left forceps handle 120 and the upper side of the right side wall of the right forceps handle 120, a reinforcing bolt 150 is screwed. The reinforcing bolt 150 is used to fix the position of the clamping block 142. The end of the reinforcing bolt 150 extends into the inner cavity of the sliding groove 141, penetrates through the fixing spring 143 and contacts one end of the clamping block 142 located in the inner cavity of the sliding groove 141. On the left side wall of the left forceps handle 120 and the right side wall of the right forceps handle 120, a gripping groove is formed. The gripping groove is used to facilitate the gripping of the forceps handle 120. Rotate the reinforcing bolt 150 to make the reinforcing bolt 150 away from the clamping block 142. Rotate the forceps handle 120 through the connecting block 119. When the forceps handle 120 rotates, the connecting block 119 presses the clamping block 142 and cooperates with the sliding groove 141 to press the fixing spring 143 so that the clamping block 142 contracts into the sliding groove 141 and thus disengages from the current adjustment groove 140. When rotated to the position that needs to be adjusted, the fixing spring 143 rebounds to drive the clamping block 142 to rebound and snap into the adjusted adjustment groove 140, and then rotate the reinforcing bolt 150 in the reverse direction to make the reinforcing bolt 150 contact the clamping block 142, thereby adjusting the position of the forceps handle 120;
[0032] In summary, it is convenient for doctors to grasp when operating at some relatively tricky angles.
[0033] In specific use, when a person skilled in the art uses it, the pliers head 114 is inserted into the installation groove 112 through the insertion block 113 and the slot 111. The auxiliary block 130 is clamped with the slot 111 for preliminary fixation. The bidirectional lead screw 116 is rotated by the knob 117. The rotation of the bidirectional lead screw 116 drives the two fixing blocks 118 to move towards each other and then enter the fixing groove 115 to be clamped with the fixing groove 115, so as to install the pliers head 114 through the fixing insertion block 113. When disassembly is required, only the knob 117 needs to be rotated in the reverse direction. When encountering a tricky angle, the reinforcing bolt 150 is rotated to make the reinforcing bolt 150 away from the clamping block 142. The pliers handle 120 is rotated through the connecting block 119. When the pliers handle 120 rotates, the connecting block 119 presses the clamping block 142 and cooperates with the chute 141 to press the fixing spring 143 so that the clamping block 142 shrinks into the chute 141 and thus disengages from the current adjustment groove 140. When rotated to the position to be adjusted, the fixing spring 143 rebounds to drive the clamping block 142 to rebound and snap into the adjusted adjustment groove 140, and then the reinforcing bolt 150 is rotated in the reverse direction to make the reinforcing bolt 150 contact the clamping block 142, thereby adjusting the position of the pliers handle 120.
