Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments.
The first embodiment is as follows:
referring to fig. 1-7, a multifunctional oral cavity scalpel comprises an extension rod 1, a locking core 2 for locking a blade, a handle sleeve 3 for tightening the locking core 2, and a blade 4 detachably arranged at the front end of the locking core 2, wherein the blade 4 is integrally formed by a handle 41 at the tail end and a blade 42 at the front end, the handle 41 is rectangular, and the blade 42 is a circular arc double-sided blade. The front end of the extension rod 1 is provided with a mounting hole 121 along the axial direction, an internal thread is arranged in the mounting hole 121, the front end of the locking core 2 is provided with a rectangular hole 24 along the axial direction, the front end of the locking core 2 is also provided with a linear opening 23 which divides the front end of the locking core into two parts in bilateral symmetry, and the outer wall of the tail end of the locking core 2 is provided with an external thread and is in threaded connection with the mounting hole 121; the handle sleeve 3 is arranged at the front end of the extension rod 1 and sleeved outside the locking core 2. The extension rod 1 is provided with a tail end extension part 11, a middle screwing part 12 and a front end nesting part 13 which are integrally formed, and the diameter of the screwing part 12 is larger than that of the extension part 11 and the nesting part 13. The mounting holes 121 penetrate through the screwing part 12 and the hitching part 13, and vertical grains are uniformly distributed on the outer wall of the screwing part 12. The locking core 2 is formed by a connecting part 21 at the tail end and a locking part 22 with the arc-shaped front end in an integrated mode, and external threads are arranged on the outer wall of the tail end of the connecting part 21. The front end of the handle sleeve 3 runs through along the axis direction and is provided with a locking hole 31, the front end of the locking hole 31 is in a horn shape, the outer wall of the handle sleeve 3 is provided with a knurl, and the tail end of the handle sleeve 3 is sleeved on the sleeving part 13.
