The universal coupling 102 is arranged between the right side of the guide plate 101 and the outer left side of the n-type plate 106. The top of the coupling 102 is connected to the right side of the reciprocating screw rod 10 through a bevel gear transmission, the rotating shaft 103 is connected to a pulley 104 through a one-way clutch, the lower part of the universal coupling 102 is also connected to a pulley 104, a flat belt 105 is wound between the two pulleys 104, a limit assembly is arranged between the winding roller 11 and the bed body 1, when the limit assembly is in operation, the limit assembly can realize the tightening and limiting of the patient's chest position; the limit assembly includes a coil spring 112, a strap 113, a hanging ring 114 and a hook 115, a coil spring 112 is connected between the right side of the winding roller 11 and the right side surface inside the n-type plate 106, a strap 113 is wound around the winding roller 11, the head end of the strap 113 is fixedly connected to two hanging rings 114, two hooks 115 are fixedly connected to the left side of the rear side of the bed body 1, and the hook 115 corresponds to the hanging ring 114.

[0034] Initially, the liquid-filling cylinder 9 and the fixed cylinder 8 are both filled with an appropriate amount of disinfectant. First, the patient lies on the bed 1 and puts his head into the electric placement frame 3. Then, the electric placement frame 3 is started to swing. The swing of the electric placement frame 3 drives the patient's head to swing to an angle. When the patient's head is adjusted to a suitable angle for caries treatment, the electric placement frame 3 is closed, and the hanging ring 114 is pulled backward to pull out the strap 113, so that the strap 113 moves backward. The pulling out of the strap 113 drives the winding roller 11 to rotate forward, and the winding spring 112 is compressed. The forward rotation of the winding roller 11 drives the rotating shaft 103 to rotate forward. Due to the action of the one-way clutch, the forward rotation of the rotating shaft 103 will not drive the pulley 104 to rotate forward. The strap 113 moves backward and is above the patient's chest, and then the hanging ring 114 is hung on the hook. 115, loosen the hanging ring 114, the hook 115 fixes the strap 113 through the hanging ring 114, and the strap 113 binds the patient's chest to prevent the patient from moving around and affecting the dentist's treatment of caries, thereby assisting the dentist in treating caries, and then pull the L-shaped plate 62 to swing backward ninety degrees, the L-shaped plate 62 swings backward and drives the limit block 5 to swing backward, the limit block 5 swings backward to the outside of the shell 4, and when the limit block 5 swings backward ninety degrees, stop pulling the L-shaped plate 62 to continue swinging, at this time the limit block 5 is above the patient's mouth, the patient opens his mouth, twists the adjusting screw 64 to rotate forward to drive the L-shaped plate 62 to move downward, the L-shaped plate 62 drives the limit block 5 to move downward to a position in the patient's mouth close to the lips, and stops twisting the adjusting screw 64, that is, The two-way screw rod 63 can be twisted to rotate forward to drive the two limit blocks 5 to move away from each other. The two limit blocks 5 move away from each other to support the patient's mouth to prevent the patient's mouth from closing and affecting the dentist's treatment of caries. When the two-way screw rod 63 is stopped, the dentist can use the treatment tool to treat the patient's caries. During the treatment, the dentist's hands can be placed on the L-shaped plate 62. The L-shaped plate 62 supports and assists the dentist's hands, so that the dentist can save more effort and relax his wrists when treating the patient, thereby better performing the treatment. The patient's chest is tied to prevent the patient from moving around and affecting the dentist's treatment and causing medical accidents, thereby ensuring the safety of the treatment. When the patient's caries treatment is completed, the dentist's hands are disconnected from the L-shaped plate 62. The two-way screw rod 63 is twisted to reverse and drive the two limit blocks 5 to move toward each other and reset, and the limit block 5 stops supporting and limiting the patient's oral cavity, and then the adjusting screw rod 64 is twisted to reverse and drive the L-shaped plate 62 to move upward and reset, and the L-shaped plate 62 drives the limit block 5 to move upward and reset to the outside of the oral cavity, and then the L-shaped plate 62 is pushed to swing left ninety degrees to reset, and the L-shaped plate 62 drives the limit block 5 to swing left and reset to the inside of the shell 4, and then the dentist pulls the hanging ring 114 to disengage from the hook 115, pulls the hanging ring 114 to move forward and reset, drives the strap 113 to move forward and stop tying the patient, and the patient can get off the bed 1, and at the same time the strap 113 moves forward and is loosened, and due to the action of the winding spring 112, the winding roller 11 reverses and rewinds the strap 113,At the same time, the reversal of the winding roller 11 drives the rotating shaft 103 to reverse, and the reversal of the rotating shaft 103 drives the front pulley 104 to reverse through the one-way clutch, and the reversal of the front pulley 104 drives the rear pulley 104 to reverse through the flat belt 105, and the reversal of the rear pulley 104 drives the universal coupling 102 to rotate, and the rotation of the universal coupling 102 drives the reciprocating screw rod 10 to rotate through the bevel gear transmission, and the rotation of the reciprocating screw rod 10 drives the movable piston rod 81 to move left and right. When the movable piston rod 81 moves to the left, the movable piston rod 81 pushes the disinfectant in the fixed cylinder body 8 into the spray head 82, and the spray head 82 sprays the disinfectant on the brush 7. When the movable piston rod 81 moves to the right, the movable piston rod 81 draws the disinfectant in the liquid cylinder 9 into the fixed cylinder body 8 through the liquid extraction tube 83. This is repeated, so that the disinfectant can be continuously sprayed out. At the same time, the reciprocating screw rod 10 also drives the brush 7 to move left and right. The movement drives the nozzle 82 to move left and right. When the nozzle 82 moves to the bottom of the limit block 5, the nozzle 82 also sprays disinfectant on the limit block 5. The brush 7 moves left and right to contact the limit block 5 after use. The brush 7 cleans and disinfects the limit block 5 after use with the disinfectant. The curtain 41 blocks the sprayed disinfectant to prevent the disinfectant from spraying and adhering to the electric placement frame 3 to affect the use, thereby ensuring the cleanliness of the electric placement frame 3. The waste liquid after cleaning and disinfection falls into the shell 4, and the shell 4 discharges the waste liquid through the drain pipe for treatment. In this way, the limit block 5 after use can be automatically cleaned and disinfected without manual cleaning and disinfection, thereby improving the safety and efficiency of treatment. When the winding roller 11 stops reversing, the winding roller 11 stops driving the rotating shaft 103 to reverse, and the reciprocating screw rod 10 also stops driving the brush 7 and the movable piston rod 81 to move left and right, and the nozzle 82 stops spraying the disinfectant.

[0035] See also Figure 6 and Figure 7 As shown, the auxiliary equipment for treating dental caries in children also includes a buffer component installed between the inclined plate 2 and the electric placement frame 3, and the buffer component includes an airbag 12, an arc-shaped cylinder body 121, an arc-shaped piston rod 122 and a guide tube 123. The airbag 12 is fixedly connected to the right side of the top of the inclined plate 2, and the airbag 12 is located on the right side of the electric placement frame 3. When the airbag 12 is inflated, the airbag 12 can support and buffer the patient's neck. The bottom of the inclined plate 2 is fixedly connected to the arc-shaped cylinder body 121, and the inner side of the arc-shaped cylinder body 121 is slidably connected to the arc-shaped piston rod 122. The left end of the arc-shaped piston rod 122 penetrates the inclined plate 2 and is fixedly connected to the left side of the outer bottom of the electric placement frame 3. The guide tube 123 is connected to the left side of the top of the arc-shaped cylinder body 121, and the tail end of the guide tube 123 penetrates the inclined plate 2 and is connected to the bottom of the airbag 12.

[0036] See also Figure 8 and Fig. 9As shown, the auxiliary equipment for treating dental caries of children also includes a support assembly installed on the bed body 1, and the support assembly includes a support plate 13, an elastic telescopic rod 131, an L-shaped mounting plate 132 and a rotating rod 133. The right side of the bed body 1 is rotatably connected with the support plate 13, and the support plate 13 can support the patient's legs. The right side of the bottom of the bed body 1 is symmetrically fixed with an L-shaped mounting plate 132 front and back, and a rotating rod 133 is rotatably connected between the lower parts of the front and rear L-shaped mounting plates 132. The middle part of the rotating rod 133 is rotatably fitted with an elastic telescopic rod 131, and the top of the elastic telescopic rod 131 is rotatably connected to the bottom of the support plate 13.

[0037] When the electric placement frame 3 swings to drive the patient's head to swing for angle adjustment, the electric placement frame 3 swings upward to drive the arc piston rod 122 to move upward, and the arc piston rod 122 moves upward to push the air in the arc cylinder 121 into the guide tube 123, and the air in the guide tube 123 is discharged into the airbag 12. As the air is discharged, the airbag 12 continues to expand and contact the patient's neck. The airbag 12 supports and limits the patient's neck, so that the patient's neck is more comfortable to lean on. When the electric placement frame 3 stops swinging upward, the electric placement frame 3 stops driving the arc piston rod 122 to move upward, and the airbag 12 stops expanding. When the electric placement frame 3 swings downward to reset, the electric placement frame 3 drives the arc piston rod 122 to move downward to reset. The arc piston rod 122 resets and draws the air in the airbag 12 back to the arc cylinder 121 through the guide tube 123. As the air is drawn away, the airbag 12 continuously shrinks and resets. In this way, the patient's neck can be prevented from being in a suspended state and causing discomfort, thereby improving the comfort of the patient's neck.

[0038] When the patient lies on the bed 1, the patient's legs can be placed on the support plate 13, and the support plate 13 supports and limits the patient's legs. Due to the function of the elastic telescopic rod 131, the support plate 13 can cushion the patient's legs to prevent the rigid fixation of the support plate 13 from causing discomfort to the patient's legs. When the dentist completes the treatment of the patient's caries, the patient gets off the bed 1, and the patient's legs are out of contact with the support plate 13. In this way, the patient's legs can be placed comfortably, thereby improving the comfort of treatment.

[0039] See also Fig.10 As shown, the auxiliary device for treating children's tooth caries also includes a cushion 14, and the cushion 14 is fixedly connected to the top of the bed body 1.

[0040] When the patient lies on the bed 1, the patient contacts the cushion 14, and the cushion 14 can support the patient, thus preventing the patient from being in hard contact with the bed 1 and feeling uncomfortable while lying, thereby further improving the comfort of treatment.
