The invention provides dental forceps with a depth limiting baffle, and relates to the technical field of medical instruments, the dental forceps comprise working assemblies and a depth control assembly, the two working assemblies intersect and are rotatably connected to form a rotating joint, and the rotating joint is connected with the depth control assembly; the depth control assembly at least comprises an adjusting knob and a limiting baffle connected with the adjusting knob, the height of the limiting baffle is adjusted through rotation of the adjusting knob, and the adjusting knob is connected to one side of the rotating joint. The working assembly comprises forceps beaks and handles, and the adjusting knob and the limiting baffle are both located between the two handles. An adjusting gear is connected to the end, close to the rotating joint, of the limiting baffle and movably connected with the adjusting knob. Limiting lugs are connected to the side portions of the rotating joints, and an adjusting gear is connected between the two limiting lugs. The problems that in the prior art, the dental forceps cannot effectively control the insertion depth of the forceps beak and are poor in universality are solved.

This utility model discloses a self-locking oral forceps, including a first clamping arm and a second clamping arm fixedly connected at their tail ends, with a self-locking assembly between the first and second clamping arms. The self-locking assembly includes a support rod, an adjusting roller, and a locking nut. The adjusting roller is fixedly installed in the middle of the support rod and coaxially arranged with it. The first and second clamping arms have interconnected support through holes and limiting strip holes. Both ends of the support rod pass through the support through holes and limiting strip holes in sequence, extending to the outside of the first and second clamping arms and connecting with the locking nut. The locking nut has a limiting block that matches the limiting strip hole. Both ends of the support rod are machined with external threads in opposite directions. The inner walls of the inner holes of a pair of fixing nuts are machined with internal threads that match the external threads at the corresponding ends of the support rods. The structure of the self-locking assembly of this utility model allows for flexible adjustment of the tightness of the clamped object, saving time and effort during operation.
