Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is further described.
Dental handpiece target drill as shown in Figures 1 to 4, comprise first body of rod 1 be equipped with dental handpiece, second body of rod 2 coordinated with the first body of rod 1 transmission, be arranged at the adapter 3 between first body of rod 1 and second body of rod 2, the inside of adapter 3 is formed with containing cavity 35, the top of first body of rod 1 and the bottom of second body of rod 2 are to inserting in containing cavity 35, the top end of first body of rod 1 is provided with interlock groove 11, specifically, the cross section of interlock groove 11 is regular hexagon, transmission stability is higher, processing more for convenience, the bottom terminal ends of second body of rod 2 is provided with the interlock projection 21 suitable with the groove 11 that links, spring 4 is provided with in containing cavity 35, spring 4 is to being located between first body of rod 1 and second body of rod 2, the top of second body of rod 2 is provided with bore portion 22, bore portion 22 is spherical in semicircle.
The above forms agent structure of the present utility model.
First body of rod 1 is for being connected with dental handpiece, when carrying out boring operation, by inconsistent with object 5 for the bore portion 22 of second body of rod 2, now spring 4 forced compression, as shown in Figure 3, makes interlock protruding 21 be inserted in interlock groove 11, now first body of rod 1 and second body of rod 2 are in transmission connection, start dental handpiece, drive the second body of rod 2 synchronous axial system, to hole to object 5 by first body of rod 1; After bore portion 22 drills object 5, object 5 is to the conflict event resolves of second body of rod 2, interlock protruding 21 is departed from interlock groove 11 under the restoring force effect of spring 4, as shown in Figure 4, gearing now between first body of rod 1 and second body of rod 2 disappears, and second body of rod 2 stops operating at once.By arranging said structure, when this utility model and dental handpiece support the use, effectively reducing operation easier when healthcare givers performs the operation, avoiding the organ or tissue injured beyond object 5, operation more for convenience.
As a kind of preferred implementation, adapter 3 comprises the first connecting plate 31 with the first body of rod 1 corresponding matching, with the second connecting plate 33 of the second body of rod 2 corresponding matching, the center of the first connecting plate 31 is provided with first through hole 311 that can pass for first body of rod 1, the top of first body of rod 1 is provided with the first stop lug 13 coordinated with the first through hole 311, specifically, the diameter of the first stop lug 13 is greater than the diameter of the first through hole 311, by the first stop lug 13 and the first connecting plate 31 counter stopper, avoid coming off between first body of rod 1 and adapter 3, the periphery of the first connecting plate 31 is upwards extended the first cylinder 32, the center of the second connecting plate 33 is provided with second through hole 331 that can pass for second body of rod 2, the bottom of second body of rod 2 is provided with the second stop lug 23 coordinated with the second through hole 331, the diameter of the second stop lug 23 is greater than the diameter of the second through hole 331, by the counter stopper of the second stop lug 23 and the second connecting plate 33, avoid coming off between second body of rod 2 and adapter 3, the periphery of the second connecting plate 33 is extended downwards the second cylinder 34 coordinated with the first cylinder 32, first cylinder 32 is threaded with the second cylinder 34, fixed effect is better, install more for convenience, first connecting plate 31, first cylinder 32, second connecting plate 33 and the second cylinder 34 coordinate formation containing cavity 35.
The above is only better embodiment of the present utility model, therefore all equivalences done according to structure, feature and the principle described in this utility model patent claim change or modify, and are included in this utility model patent claim.
