Embodiment
The principle and feature of the present invention are described below in conjunction with accompanying drawing, the given examples are served only to explain the present invention, and It is non-to be used to limit the scope of the present invention.
As shown in Figure 1, Figure 2 with shown in Fig. 3, Fig. 4, a kind of orthopaedics takes nail guide, including base 12, and the side of base 12 passes through master Bolt 9 has been hinged and connected vertical adjustment bar 8, and main bolt 9 screws tight rear, vertical adjustment bar 8 and is positioned at the side of base 12, Movable sleeve is rotated against on vertical adjustment bar 8 and is installed with vertical sliding sleeve 7, the sidewall thread of vertical sliding sleeve 7, which is connected with, can make vertically Sliding sleeve 7 is positioned at the vertical bolt 6 on vertical adjustment bar 8, and the inner end of vertical bolt 6 withstands on the side of vertical adjustment bar 8 Face, the vertical side of bolt 6, which is integrally fixedly connected with, to be rotated against movable sleeve on lateral adjustments bar 5, lateral adjustments bar 5 and is installed with Horizontal sliding sleeve 3, the sidewall thread of horizontal sliding sleeve 3 be connected with can make horizontal sliding sleeve 3 be positioned at the transverse direction on lateral adjustments bar 5 determine Position bolt 4, the inner end of located lateral bolt 4 withstands on the side of lateral adjustments bar 5, and the horizontal outside of sliding sleeve 3, which is rotated against, is connected with set Cylinder 1, sleeve 1 is located at the top of base 12.Vertical adjusting rod 8, lateral adjustments bar 5 and horizontal sliding sleeve 3 and set are rotated by adjusting Cylinder 1, is capable of the angle and direction of control sleeve 1, makes screwdriver just to screw, to be operated.
Activity is plugged with inner core 2 in the sleeve 1, and inner core 2 includes cylinder, the lateral wall of cylinder and the madial wall of sleeve 1 Supporting table 17 is integrally fixedly connected with outside interference fit connection, the upper port edge of cylinder, supporting table 17 is located at the upper of sleeve 1 Above port.
