Abstract
The utility model provides a power-output shaft for portable pneumatic machines or electric machines, which is characterized in that the head of the power-output shaft has the connection configurations for power transmission as follows: a square connection configuration or one of the connection configurations besides the square configuration: a polygonal prism, a column with at least one torque force transmission surface besides the polygonal prism, and a column with a plurality of torque force transmission grooves; behind the configurations, the power-output shaft is provided with a section of threaded column; according to the axial projection of the power-output shaft, the projection of the head is positioned in the projection of the threaded column. The utility model has the advantages of connection with tools with various connection modes, great saving of the equipment cost of users, and reduction of carrying burden in outdoor; when equipped with the utility model by users, the portable pneumatic machine or electric machine can be connected with tools with various connection modes.
Description
Technical field
The utility model relates to a kind of power output shaft that is applied on portable pneumatic machinery or the motor machine.
Background technology
Portable pneumatic machinery or motor machine are common equipments on the production line made of automobile, motorcycle or other electronic product or the assembly line, such as, loading and unloading tire or other operation in automobile, motorcycle are made just need to use electric wrench or pneumatic impact spanner.The power output shaft that is applied at present on portable pneumatic machinery or the motor machine can only adapt to a certain connected mode, therefore, when the user need use some different instruments, needs to be equipped with many portable pneumatic machinery or motor machine.This situation also is present in family to be used, and in the family of having deep love for doing it yourself to finish, needs to be equipped with some different instruments, for this reason, has to be equipped with many portable pneumatic machinery or motor machine, has therefore increased a large amount of expenses and has paid.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of instrument the portable pneumatic machinery or the electromechanical power output shaft that cooperate or connect that can be different with connected mode.For this reason, the utility model is by the following technical solutions: its head is the following connection configuration that is used for transmission of power: four directions or the following connection configuration except that the four directions a kind of: polygon prism, except that prism at least simultaneously for the cylindricality of torsion transfer surface, have the cylindricality of transmission torsion groove; After above-mentioned configuration, described power output shaft has one section threaded post; According to the axis projection of power output shaft, the projection of described head is within the projection of described threaded post.Owing to adopt the technical solution of the utility model, the utility model can be connected by the instrument different with connected mode, the user is equipped with one and portable pneumatic machinery of the present utility model is installed or motor machine can be connected by the instrument different with connected mode, carries burden when greatly having saved user's installation cost expenditure and also having reduced out using.

The specific embodiment
With reference to accompanying drawing.Portable pneumatic machinery provided by the utility model or electromechanical power output shaft 9, its head is the four directions 93 that is used for transmission of power, after four directions 93, described power output shaft has one section threaded post 92; According to the axis projection of power output shaft, the projection of described head is within the projection of described threaded post.
Described power output shaft head is provided with threaded connection hole 94, the center line of described threaded connection hole and the central lines of power output shaft, like this, this threaded connection hole can play the effect that further reinforcement connects with the instrument that screw fit is connected power output shaft 9.。
Described power output shaft also has dismounting opposite side 91 at the threaded post rear.
The side of described head is provided with spring eye 95, the ball 72 that is provided with spring 71 in the described spring eye and is pushed to the aperture direction by spring.
With reference to accompanying drawing 2,4,5,6.Head of the present utility model can be connected with Wrench, make portable pneumatic machinery of the present utility model or motor machine are installed, after connecting Wrench, promptly become electric wrench or pneumatic impact spanner, threaded post of the present utility model can be connected with drill chuck, after pulling down Wrench and changing drill chuck 1, portable pneumatic machinery of the present utility model or motor machine are installed promptly becomes electric drill or pneumatic boring bar tool.The utility model is connected with instrument reliably, and is very easy to use, and can be the user and save equipment investment.In the drawings, drawing reference numeral 10 is the main body of hand electric machinery.
Difference according to connected mode, head of the present utility model, except that the four directions, also can adopt any of the following connection configuration that is used for transmission of power: polygon prism, the one side at least except that prism for the cylindricality of torsion transfer surface, have the cylindricality of transmission torsion groove.
