Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

Given by fig. 1 to 5, fagging 1 including the fore-and-aft direction, the left and right sides of fagging 1 lower extreme rear side is equipped with splint 2 respectively, left splint 2 can control the left and right sides, fagging 1 upper end rear side swivelling joint has opening box body 3 up, sliding connection has slide 4 in the box body 3, slide 4 lower extreme is through spring and box body 3 fixed connection, slide 4 upper end sliding connection has the tong arm 5 of two upper and lower directions, relative and the left and right sides respectively can be controlled and remove about two tong arm 5, it is connected with axial pivot 6 around the last rotation of box body 3 front side wall, pivot 6 front end runs through box body 3 and is equipped with depression bar 7, pivot 6 rear end inserts in the box body 3 and is equipped with the ejector pin 8 that can contact with slide 4, the length of depression bar 7 is greater than the length of ejector pin 8.

In order to enable the left clamping plate 2 to move left and right, a sliding groove 9 with a downward opening and a front-back direction is formed in the supporting plate 1, a moving plate 10 with a lower end fixedly connected with the front clamping plate 2 is connected in the sliding groove 9 in a sliding mode, a left-right axial T-shaped screw rod 11 is in threaded connection with the left side of the supporting plate 1, the right end of the T-shaped screw rod 11 is in rotating connection with the moving plate 10, and the left end of the T-shaped screw rod 11 penetrates through the supporting plate 1.

In order to move the clamp arm 5 left and right, a front side wall of the box body 3 is provided with a guide groove 12 which penetrates through the front and back and is in the left and right direction, two operation plates 13 which are opposite to each other in the left and right direction are connected in the guide groove 12 in a sliding mode, and the upper end of the clamp arm 5 penetrates through the corresponding operation plate 13 and is connected with the corresponding operation plate 13 in a sliding mode.

In order to move the operating plate 13 conveniently, the operating plate 13 is in an inverted L shape, and the front end surface of the operating plate 13 is positioned between the supporting plate 1 and the pressing rod 7.

In order to avoid pinching the patient, the two splints 2 are provided with respective elastic pads 14 at their opposite ends.

In order to achieve better use effect, the lower end face of the ejector rod 8 can be attached to the upper end face of the sliding plate 4.

When the utility model is used, the lower end face of the ejector rod 8 is attached to the upper end face of the sliding plate 4, the left end of the movable plate 10 is in contact with the sliding groove 9 in an initial state, the patient opens the oral cavity, the two clamp plates 2 are placed in the oral cavity of the patient, the teeth which are opposite to the teeth needing tooth extraction are placed between the two clamp plates 2, at the moment, the T-shaped screw 11 is rotated clockwise, the T-shaped screw 11 rotates and simultaneously drives the movable plate 10 to move towards the right clamp plate 2, the movable plate 10 drives the left clamp plate 2 to synchronously move towards the right clamp plate 2, when the elastic cushions 14 at the two sides are in contact with and extrude the teeth of the patient, the T-shaped screw 11 stops rotating, and the T-shaped screw 11 is loosened due to the self-locking property of the threads, and the support plate 1 is fixed;

after the supporting plate 1 is fixed, one hand clockwise rotates the pressure lever 7, the pressure lever 7 drives the ejector rod 8 to synchronously clockwise rotate through the rotating shaft 6, when the lower end of the ejector rod 8 is separated from the sliding plate 4, the sliding plate 4 moves upwards under the action of the elastic force of the spring, the sliding plate 4 drives the two forceps arms 5 to simultaneously move upwards, and in the process that the forceps arms 5 move upwards, one hand holds the two operating plates 13, and enables the operating plate 13 on the right side to be in contact with the right side wall of the guide groove 12, and the operating plate 13 on the left side to be in contact with the left side wall of the guide groove 12 on the left side, so that teeth of a patient needing tooth extraction are positioned between the two forceps arms 5;

along with the upward movement of the sliding plate 4, when the two forceps arms 5 can be contacted with teeth of a patient needing tooth extraction, the rotation of the pressure lever 7 is stopped, the two forceps arms 5 are rotated, the forceps arms 5 are parallel to the teeth of the patient, at the moment, the two forceps arms 5 are relatively extruded, the two forceps arms 5 move relatively, after the two forceps arms 5 are respectively contacted with and extrude the teeth of the patient needing tooth extraction, the holding force on the forceps arms 5 is kept, the pressure lever 7 rotates anticlockwise, the pressure lever 7 drives the ejector rod 8 to rotate anticlockwise through the rotating shaft 6, the ejector rod 8 pushes the sliding plate 4 to move downwards, the sliding plate 4 drives the forceps arms 5 to move downwards, the forceps arms 5 pull the teeth of the patient needing tooth extraction downwards, and as the length of the pressure lever 7 is greater than that of the ejector rod 8, namely, the force arm of the pressure lever 7 is greater than that of the ejector rod 8, when the structure is a labor-saving structure, the physical strength expenditure of a doctor can be effectively reduced;

after the teeth of the patient are pulled out, the pressing rod 7 continues to rotate anticlockwise, the pressing rod 7 continues to drive the ejector rod 8 to rotate through the rotating shaft 6, the ejector rod 8 continues to push the sliding plate 4 to move downwards until the lower end face of the ejector rod 8 is attached to the upper end face of the sliding plate 4, at the moment, the T-shaped screw 11 rotates anticlockwise, the T-shaped screw 11 simultaneously drives the moving plate 10 to be far away from the clamping plate 2 on the right side, the moving plate 10 drives the clamping plate 2 on the left side to be far away from the clamping plate 2 on the right side, and when the clamping plates 2 on the two sides are respectively separated from the teeth of the patient, the clamping plate 2 is moved out.

The utility model discloses simple structure, convenient operation conceives the novelty, and the practicality is strong, and left splint, two that set up and to remove about can removing and the tong arm that can reciprocate, the slide that can reciprocate and the arm length are greater than the depression bar of ejector pin, are convenient for at the fixed fagging of tooth extraction in-process, have saved doctor's physical power, and it is long when having reduced the operation, have increased the efficiency of operation and patient's comfort level.
