The fixing piece is a fixing cap sleeved on the end head and is connected with a connecting surface fixed on the handle.

The front end of end is equipped with the second protection surface, and second protection surface lower extreme inboard is equipped with the speculum, it leans out to become the contained angle of 30-45 degrees between speculum and the car needle, the base of second protection surface is located the needle point of car needle upwards 2-6mm department.

Be provided with on the connection face with handle assorted buckle mechanism, buckle mechanism is including articulating first arc spare and the second arc spare on connecting the face, the free end of first arc spare articulates there is the locking piece, the tip of locking piece is provided with the buckle, the surface of second arc spare be provided with buckle assorted draw-in groove.

And a hollow window is arranged in the middle of the first protective surface.

Aiming at the problem that the buccal surface or the tongue of the oral cavity of a patient is easily scratched by the existing dental prosthesis mobile phone in the using process, the invention designs the special structure which is simple in structure, ingenious in design and reasonable in layout, and the arranged first protection surface can effectively prevent the needle from contacting with the buccal surface or the tongue of the oral cavity, avoid the accident of damaging the buccal surface or the tongue of the oral cavity and ensure the normal work of the needle. The fixing cap sleeved on the end head is used as a fixing piece, so that the fixing cap can be quickly assembled and disassembled with the end head, and the first protection surface is convenient to replace; meanwhile, the reflector is arranged on the inner side of the second protection surface positioned at the front end of the end head, so that a dentist can directly observe the occlusal surface of a tooth through the reflector, and the tooth repairing operation is facilitated; the designed buckle mechanism capable of being fixed on the handle can ensure that the protection surface and the like are stably connected with the handle, and further ensures safety.

Detailed Description

The invention discloses a tooth trimming mobile phone capable of protecting oral cavity soft tissue, which is shown in figures 1 to 4: the same as the existing tooth-repairing mobile phone is that the tooth-repairing mobile phone is provided with a handle 1 and an end 2 connected with the handle 1, the lower end of the end 2 is provided with a needle 3, one end of the end 2 far away from the handle 1 is a front end, the side surface between the front end and the handle is divided into a front side surface and a rear side surface, the tooth-repairing mobile phone is different from the prior art that the handle 1 or/and the end 2 are provided with fixing pieces 4, the fixing pieces 4 can be fixed on the handle 1 or/and the end 2 in various detachable modes, and a first fixing piece 4 is connected with the fixing pieces 4

The protective face 5 is located on the front side face or the back side face of the end head 2, and the first protective face 5 can be selected to be located on the front side face or the back side face according to the upper, lower, left and right positions of a restored tooth in an oral cavity and used for isolating the needle 3 from the buccal surface of the oral cavity or isolating the needle 3 from the tongue. And each edge of the first protection surface 5 is chamfered and smoothed, and the bottom edge of the first protection surface 5 is positioned 2-6mm above the needle point of the needle 3. The first protection surface 5 can effectively prevent the needle 3 from contacting buccal surfaces or tongues of the oral cavity, avoid accidents of damaging the buccal surfaces or the tongues of the oral cavity, and can ensure the normal work of the needle 3.

The fixing part 4 can be a fixing cap sleeved on the end head 2, the fixing cap and the end head 2 can adopt a closely connected fixing mode, and can also adopt inserting modes such as a convex strip and a groove to realize fixing, and meanwhile, the fixing cap and the fixing cap are connected with a connecting surface 6 buckled at the front end of the handle 1. Can realize with end quick assembly disassembly, be convenient for change first protective surface 5.

The front end of end 2 is equipped with second protective surface 7, can form L shape structure with first protective surface 5, and second protective surface 7 lower extreme inboard is equipped with speculum 8, it leans out to become the contained angle of 30-45 degrees between speculum 8 and the car needle 3, the base of second protective surface 7 is located the needle point of car needle 3 and upwards 2-6mm department. The dentist can use the second protective surface 7 to push and press soft tissues such as gingiva and the like of a far tooth, and the dentist can directly observe the tooth through the reflector, so that the tooth repairing operation is convenient.
