Detailed Description
First embodiment
As shown in fig. 1 and fig. 2, the eccentric equidistant positioning instrument of the present invention comprises: drill rod cover 5, locating plate 3, location nail 1 and handle 4, the one end of drill rod cover 5 is fixed with locating plate 3, locating plate 3 is perpendicular with drill rod cover 5, it has a plurality of locating hole 2 to open on locating plate 3, location nail 1 screws in one of them locating hole 2, location nail 1 is perpendicular with locating plate 3, can adjust the distance at locating hole 2 and drill bit hole 10 center like this as required, also can weld on locating plate 3 and fix a position nail 1 (not drawn in the picture). One end of the handle 4 is fixed to the other end of the drill casing 5, the other end of the handle 4 has a grip 6, the grip 6 has at least two grip sockets, for example: as shown in fig. 1-3, there are three gripping sockets. The handle 6 is inclined 120-130 degrees relative to the drill sleeve 5, the positioning plate 3, the positioning nail 1 and the handle 4 are on the same plane, and as shown in fig. 1, the positioning plate 3 and the handle 4 are welded and fixed on the same side of the drill sleeve 5. As shown in fig. 2, the positioning plate 3 and the handle 4 are welded and fixed to opposite sides of the drill sleeve 5.
Second embodiment
The second embodiment is substantially the same as the first embodiment, and the same parts will not be described again, except for: the utility model discloses an eccentric equidistance locater still includes: a locking nut 7 and a sleeve 8, one end of the sleeve 8 is welded on the handle 4, two symmetrical bulges 9 are arranged on the outer circumference of the other end of the sleeve 8, the bulges 9 are inserted into corresponding grooves 11 formed at the other end of the drill rod sleeve 5, threads are arranged on the outer circumference of the other end of the drill rod sleeve 5, the locking nut 7 is screwed into the outer circumference of the other end of the drill rod sleeve 5 to fix the drill rod sleeve 5 and the handle 4 together, so that when in use, the handle 4 can be adjusted to the positions shown in figures 3 and 2 according to requirements, an eccentric equidistant positioning instrument is realized, and the position of two different handles 4 is provided, thereby being more convenient for doctors to operate.
