The first clamping arm 1-1 and the second clamping arm 1-2 are symmetrically and crossly arranged, and the middle part of the first clamping arm 1-1 and the middle part of the second clamping arm 1-2 are hinged through the hinge shaft 1-3. Thus, the two side sections of the first clamping arm 1-1 are respectively a front section and a rear section, and the two side sections of the second clamping arm 1-2 are respectively a front section and a rear section.

In a locking state, the locking tooth parts 1-51 are meshed with the tooth parts 1-41 of the arc-shaped outer rack 1-4, and the locking plate 1-5 and the arc-shaped outer rack 1-4 cannot rotate at the same time, so that the gap between the first clamping tooth part 1-11 and the second clamping tooth part 1-21 is constant. Therefore, after the first tooth clamping teeth 1-11 and the second tooth clamping teeth 1-21 clamp teeth, the poking parts 1-52 of the locking plates 1-5 are poked (in the direction of F1) to rotate forwards, so that the locking teeth 1-51 are meshed with the teeth 1-41 of the arc-shaped outer racks 1-4 to be locked, and at the moment, the first tooth clamping teeth 1-11 and the second tooth clamping teeth 1-21 cannot move backwards and can always keep a firm clamping state on the teeth.

The threaded rod 2-6 is fitted into the threaded through-hole of the mounting plate portion 2-12 so that the height of the two side tooth pressing pieces 2-2 can be adjusted individually. Because the heights of the upper surfaces of the two nearest adjacent normal teeth on the two sides of the loose tooth to be pulled out are possibly inconsistent, the lower surfaces of the two side tooth pressing blocks 2-2 can be respectively attached and pressed on the upper surfaces of the two nearest adjacent normal teeth on the two sides of the loose tooth to be pulled out in an optimal state through the separated adjustment of the two side tooth pressing blocks 2-2.
Preferably, the first tooth clamping teeth 1-11 and the second tooth clamping teeth 1-21 are respectively provided with two rope sleeve slots 112, the first ends of the two pull ropes 2-3 are respectively provided with two rope sleeves 2-31, and the two rope sleeves 2-31 are respectively sleeved on the two rope sleeve slots 112.

fourthly, when the teeth are completely pulled out, the electric cylinder 2-5 is closed to work; then the automatic tooth extraction instrument and the extracted teeth are taken out from the oral cavity together, and then the automatic tooth extraction instrument can be unlocked and loosened to take out the teeth.
The invention has at least the following characteristics:
firstly, the invention can realize automatic tooth extraction, has simple operation and time and labor saving, and can firmly clamp the teeth and keep the clamped state (in a locked state) when the teeth are extracted upwards, thereby avoiding the problem that the tooth clamping mechanism is separated from the affected teeth or loose teeth when the teeth are extracted upwards;
secondly, the fixed arm is positioned above the tooth clamping mechanism, so that even if the tooth clamping mechanism is poor in clamping and loosened when clamping teeth and extracting teeth upwards, the first tooth clamping tooth part and the second tooth clamping tooth part of the tooth clamping mechanism can be blocked by the fixed arm when moving upwards, and therefore the first tooth clamping tooth part and the second tooth clamping tooth part of the tooth clamping mechanism cannot have the problem that the mouth upper jaw is damaged due to large inertia and upward movement;
thirdly, the electric cylinder is adopted to drive tooth extraction, and the electric cylinder can realize that the two pull ropes 2-3 are pulled outwards with equal force, so that the problem that the patient is painful due to too high speed and too strong force in manual tooth extraction can be solved, meanwhile, the electric tooth extractor is simple to use, and the learning difficulty and the practical operation difficulty of medical personnel are greatly reduced.
