The invention relates to a manual bone drill. The manual bone drill comprises a handle, wherein a pair of positioning bodies is arranged on the handle, a positioning column and a shaft are arranged between the positioning bodies, the shaft penetrates the positioning bodies and the positioning column, a drill chuck is arranged at one end of the shaft, a driving bevel gear is arranged on the positioning column, and driven bevel gears are arranged on the shaft and comprise a driven bevel gear A and a driven bevel gear B which have different quantities of teeth; lock screws are arranged on the driven bevel gear A and the driven bevel gear B. According to the manual bone drill, the driven bevel gear A and the driven bevel gear B are arranged on the shaft and fixed with the shaft through the lock screws, the driven bevel gear A or the driven bevel gear B can be selected conveniently according to requirements, and the rotating speed of the shaft is regulated when the rotating speeds of the bevel gears are equal.
Description
Technical field
The present invention relates to medical operating field of tool, specifically relate to a kind of Manual bone drill.
Background technology
In medical operating, bone drill is a kind of common medical apparatus and instruments, for treating that operative site is as skull is holed, so that perform the operation etc.At present, in clinical operation, the bone drill used has electric bone drill, hand bone drill and bradawl to bore three kinds, electric bone drill is made up of housing, motor, actuating device and drill chuck head, and motor and actuating device are all located in housing, and motor is fixedly connected with drill chuck head through the output shaft of actuating device, its deficiency is: electric bone drill is not easy sterilization, expensive, and wayward, easy operate miss; In the situations such as emergency treatment in the wild, still need to adopt Manual bone drill.At present, the driven wheel of common Manual bone drill and the gear ratio of driven gear immutable, only by changing the rotating speed of hand rapid change drill bit, convenient and swift not during use.
Summary of the invention
The present invention is in order to overcome deficiency of the prior art, provide a kind of Manual bone drill, Manual bone drill is by being provided with two groups of driven angular wheels varied in size in the present invention, coordinate with driving angular wheel by switching different driven angular wheels, realize the change that Manual bone drill rotates ratio, easy to use.
The present invention is achieved through the following technical solutions:
A kind of Manual bone drill, comprise handle, described handle is provided with a pair positioning body, between a pair positioning body, locating dowel is set, axle is provided with between positioning body, described axle is through positioning body and locating dowel, the termination of axle is provided with drill chuck, described locating dowel is provided with initiatively angular wheel, be provided with driven angular wheel on the shaft, described driven angular wheel comprises driven angular wheel A, driven angular wheel B, and described driven angular wheel A is different from the driven angular wheel B number of teeth; Described driven angular wheel A, driven angular wheel B are provided with lock-screw.
As an optimal technical scheme of the present invention, between described axle and a pair positioning body, be provided with bearing.
As an optimal technical scheme of the present invention, the upper end of described locating dowel is provided with cover plate, is provided with spring between cover plate and active angular wheel.
As an optimal technical scheme of the present invention, described active angular wheel is provided with rocking bar, described rocking bar is provided with rocking handle.
Compared with prior art, the invention has the beneficial effects as follows: the present invention is provided with driven angular wheel A, driven angular wheel B on axle, driven angular wheel A, to be fixed by lock-screw between driven angular wheel B and axle, conveniently selecting driven angular wheel A or driven angular wheel B as required, realizing the rotating speed of the regulating shaft when driving angular wheel rotating speed identical.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure: 1, rocking handle; 2, rocking bar; 3, locating dowel; 4, spring; 5, active angular wheel; 6, lock-screw; 7, drill chuck; 8, axle; 9, driven angular wheel A; 10, hands handle; 11, positioning body; 12, driven angular wheel B; 13, cover plate.
Detailed description of the invention
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
As shown in Figure 1, a kind of Manual bone drill, comprises handle 10, described handle 10 is provided with a pair positioning body 11, locating dowel 3 is set between a pair positioning body 11, between positioning body 11, be provided with axle 8, described axle 8, through positioning body 11 and locating dowel 3, the termination of axle 8 is provided with drill chuck 7; Described locating dowel 3 is provided with initiatively angular wheel 5, described axle 8 is provided with driven angular wheel, when initiatively angular wheel 5 rotates, driven angular wheel is driven to rotate, thus driving shaft 8 rotates, realize drill chuck 7 and drive drill bit rotational, to reach the object of carrying out when performing the operation holing.
Common Manual bone drill is only arranged a driven angular wheel, thus initiatively angular wheel 5 is constant with the gear ratio of driven angular wheel, and Manual bone drill does not possess speed-regulating function.Described driven angular wheel comprises driven angular wheel A9, driven angular wheel B12 in the present invention, and described driven angular wheel A9 is different from the driven angular wheel B12 number of teeth; Described driven angular wheel A9, driven angular wheel B12 are provided with lock-screw 6.Convenient mobile driven angular wheel A9, the driven position of angular wheel B12 on axle 8 after unclamping lock-screw 6.The driven angular wheel coordinated with active angular wheel 5 is selected in use according to the needs of drill speed.
As a preferred embodiment of the present invention, be provided with bearing between described axle 8 and a pair positioning body 11, the setting of bearing can reduce the frictional dissipation between axle 8 and positioning body 11, extends the service life of Manual bone drill.
As a preferred embodiment of the present invention, the upper end of described locating dowel 3 is provided with cover plate 13, be provided with spring 4 between cover plate 13 and active angular wheel 5, under the elastic force effect of spring 4, initiatively angular wheel 5 engaged with driven angular wheel A9 or driven angular wheel B12 all the time.
As a preferred embodiment of the present invention, described active angular wheel 5 is provided with rocking bar 2, described rocking bar 2 is provided with rocking handle 1, during use, drive rocking handle 1 to drive initiatively angular wheel 5 to rotate by rocking bar 2.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
