[0026] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] The utility model provides the following technical scheme, a kind of tooth filling device for stomatology convenient to disinfect:

[0028] Embodiment one, to solve the existing working head after dismounting not set to the working head after dismounting Automatic ejection mechanism, it can lead to the working head after dismounting still easy to be stuck in the inside of handle 1, it is not convenient for medical staff's operation and use, reduce the tooth filling device use practicality problem, disclose: two mounting seat 2's inside grooving sliding installation has top plate 10, and two top plate 10 is disc shape, and the outer end of two top plate 10 is respectively connected with presser end 3 and blunt knife 4;Two mounting seat 2's inside grooving is provided with second extrusion spring 11, and the outer end of two second extrusion spring 11 is connected with top plate 10.

[0029] As shown in Figures 1-6 When presser end 3 and blunt knife 4 are installed in the inside of two mounting seat 2, the inner end of presser end 3 and blunt knife 4 will extrude top plate 10 to extrude and slide in the inside of two mounting seat 2, at this time, two second extrusion spring 11 will store energy due to the extrusion and sliding of two top plate 10, after the dismounting and separation of presser end 3 and blunt knife 4, two second extrusion spring 11 will be elastically reset to the position of two extrusion and moving top plate 10 by its own elastic force, so that presser end 3 and blunt knife 4 can be ejected out of the outside of two mounting seat 2 through two reset and moving top plate 10, so as to facilitate the disinfection and use of presser end 3 and blunt knife 4 by medical staff in the later period, and the practicality is better.

[0030] Embodiment two, different from embodiment one, can realize quick positioning and installation of presser end 3 and blunt knife 4 after dismounting and replacing, and operation is more time-saving and labor-saving, and discloses:

[0031] The handle 1 and mounting base 2 are symmetrically mounted at the front and rear ends of the handle 1, with the outer ends of the two mounting bases 2 being inclined. A pressure end 3 and a blunt blade 4 are respectively mounted on the outer ends of the two mounting bases 2, with the pressure end 3 being pointed and the blunt blade 4 being flat. A limit block 5 is slidably mounted through slots on the inner ends of the pressure end 3 and the blunt blade 4, and the two limit blocks 5 have identical structures, with their tops extending through to the outer top of the two mounting bases 2. Limit grooves 6 are formed on the inner top of each of the two mounting bases 2. The two limit slots 6 are of the same size, and the two limit slots 6 are internally connected to limit blocks 5, and the limit blocks 5 and the limit slots 6 form a locking mechanism; the tops of the two limit blocks 5 are both inclined; the inner ends of the presser end 3 and the blunt knife 4 are provided with first compression springs 9, and the two first compression springs 9 have the same structure, and the tops of the two first compression springs 9 are connected to the limit slots 6; the bottom of the inner ends of the presser end 3 and the blunt knife 4 are provided with moving blocks 7, and the bottom outer sides of the two moving blocks 7 are slidably connected with moving grooves 8, and the two moving grooves 8 are opened on the bottom inner sides of the two mounting bases 2.

[0032] like Figures 1-5 As shown, when it is necessary to position and install the pressure end 3 and the blunt knife 4, simply slide the movable block 7 at the bottom of the inner end of the pressure end 3 and the blunt knife 4 into the movable groove 8 opened on the inner side of the bottom of the two mounting seats 2. At this time, the two limiting blocks 5 will retract and move by the squeezing of the two mounting seats 2. After the pressure end 3 and the blunt knife 4 move to the appropriate position, the two first compression springs 9 will use their own elasticity to push the two limiting blocks 5 through the two limiting slots 6 to the top outer side of the two mounting seats 2, thereby realizing the automatic positioning and fixing of the pressure end 3 and the blunt knife 4. Conversely, by holding the external squeezing rod, the limiting blocks 5 can be squeezed and retracted to move, so that the limiting blocks 5 retract and move into the inside of the pressure end 3 or the blunt knife 4, thereby separating the pressure end 3 or the blunt knife 4 from the mounting seat 2. The operation is more time-saving and labor-saving.
