Abstract
The utility model discloses a motor craniotomy saw, which belongs to an appliance for judicial doctor. A keypad switch (10) is arranged at one side of the shell (12) of a handle, a power wire (13) and a power plug-in (14) are connected at the lower end of the shell of the handle, the power wire is connected with a motor (8) in a shell at the centre (9) by the keypad switch, a taper gear (6) fixed at the upper end of a motor arbor (7) is meshed with another taper gear (3) in a shell at the head (5), one end of a saw bit axle (4) is fixed with the other taper gear (3), the other end is fixed with a saw bit (2). The utility model has simple structure and low manufacture cost, the manufacturing cost is just about one twentieth of the motor craniotomy saw sold on market, the use is convenient and is easy to hold by hands, the work efficiency is high and the labor intensity of the operator is reduced greatly.
Description
Technical field
This utility model provides a kind of legal medical expert's apparatus, especially a kind of craniotomy saw.
Background technology
The legal medical expert technical staff of system of public security organs of basic unit often runs into and will open the cranium check to the corpse in all kinds of criminal, the civil cases, to determine the cause of death etc.Be to adopt original methods such as handsaw, chiso-mallet traditionally mostly, not only time-consuming but also require great effort, it is also bad to open the cranium effect.A kind of electronic craniotomy saw is arranged now, complex structure, price higher (needing 3500～4000 yuan approximately), and, saw material little Yi Saichi close because of sawtooth, result of use is also undesirable.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of electronic craniotomy saw is provided, and to improve the convenience of using, reduces production costs.
This utility model is to realize like this, electronic craniotomy saw, it has the handle body case, handle body case one side has key switch, shank shell lower end has power line to link to each other with attaching plug, and power line links to each other with motor in the middle housing through key switch, and another interior bevel gear of the fixed bevel gear in motor reel upper end and head shell meshes together, saw blade axis one end and another bevel gear are fixed together, and the other end and saw blade are fixed together.
Adopt the electronic craniotomy saw of said structure, simple structure, production cost is low, cost only is about 1/20th of a commercially available electronic craniotomy saw, easy to use, easily hand-held, high efficiency, open cranium by original manual operations and be reduced to about 10 minutes in 70～80 minutes consuming time, alleviated operator's labor intensity greatly.
Description of drawings
Fig. 1 is the sketch map of this utility model structure.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing illustrates concrete structure of the present utility model.
As shown in drawings, the electronic craniotomy saw of this utility model, it has handle body case (12), handle body case one side has key switch (10), shank shell lower end has power line (13) to link to each other with attaching plug (14), power line links to each other with motor (8) in the middle housing (9) through key switch, the fixed angular wheel in motor reel (7) upper end (6) meshes together with another angular wheel (3) in the head shell (5), and saw blade axis (4) one ends and another angular wheel (3) are fixed together, the other end and saw blade (2) are fixed together.
There is protective cover (1) to be fixed on the head shell (5) in the outside of described saw blade (2).
During use, plug (14) is inserted in the supply socket, hold the shank shell, the switch that pushes button, motor gets electric work, drives motor reel and rotates, thereby driving angular wheel (6) rotates, angular wheel promptly drives another angular wheel (3) that meshes together with it and rotates, and another angular wheel (3) promptly drives saw blade (2) by saw blade axis (4) and rotates, and finishes out the cranium action.
Locking button (11) can also be arranged near the handle casing the key switch.Behind the switch that pushes button, press the locking button, it is stuck on the key switch, key switch can be in on-state for a long time.And needn't for a long time it be exerted pressure, thereby improved the convenience of operation.
Sawtooth on the saw blade can be provided with rarelyr, the saw material can be suitably big, with antifouling tooth.
Claims (2)
1, electronic craniotomy saw, it is characterized in that, it has handle body case (12), handle body case one side has key switch (10), shank shell lower end has power line (13) to link to each other with attaching plug (14), power line links to each other with motor (8) in the middle housing (9) through key switch, the fixed angular wheel in motor reel (7) upper end (6) meshes together with another angular wheel (3) in the head shell (5), and saw blade axis (4) one ends and another angular wheel (3) are fixed together, the other end and saw blade (2) are fixed together.
