Description
Technical field
The utility model relates to screw mandrel technical field, especially relates to the special screw mandrel of a kind of massage chair.
Background technique
Leading screw is the transmission component that precision optical machinery the most often uses, and its major function converts rotary motion to linear motion, or torque axis is changed into axial repeated action power, has highi degree of accuracy, reversibility and high efficiency feature concurrently simultaneously.But when existing screw mandrel is used for massage chair, because massage chair needs the transmission of screw mandrel to reach the effect of mobile massage, and existing screw mandrel uses and beats comparatively greatly on massage chair, and utilization efficiency and precision are not high, thus affect working life yet.
Model utility content
For the deficiency that above-mentioned prior art exists, the purpose of this utility model is to provide the special screw mandrel of a kind of massage chair, and it is high that it has utilization efficiency, and precision is high, and beating of whole rhizoid bar is little, the feature of long service life.
To achieve these goals, the technological scheme that the utility model adopts is: the special screw mandrel of a kind of massage chair, comprise the body of rod, described body of rod one end is connected with the first bar head, the body of rod the other end is connected with the second bar head, first bar head outer end is coaxially connected with the 3rd bar head, and be provided with connecting rod between the first bar head and the body of rod, connecting rod is provided with connection bit.
Wherein, described first bar head and connecting rod are located between the second bar head and the body of rod.
Wherein, described connecting rod is located between the second bar head and the body of rod, and the first bar head is located at the body of rod and the 3rd
Between bar head.
Wherein, the large footpath of described first bar head and the second bar head is equal.
After adopting said structure, the utility model is compared to the prior art advantageously: it comprises the body of rod, described body of rod one end is connected with the first bar head, the body of rod the other end is connected with the second bar head, first bar head outer end is coaxially connected with the 3rd bar head, connecting rod is provided with between first bar head and the body of rod, connecting rod is provided with connection bit, the utility model is by adopting the screw mandrel to hair style, this screw mandrel is the screw mandrel with three heads, has utilization efficiency high, and precision is high, beating in 0.1mm of whole rhizoid bar, therefore long service life.
