Description
Technical field
The present invention relates to manipulator technical field, in particular to a kind of prosthetic hands.
Background technology
Artificial limb is exactly the means and method with engineering technology, special to make up the limbs of amputee or limbs Partial defect
Door design and the artificial prosthesis for making assembly, also known as " artifucial limb ".Its main function is the partial function for replacing losing limbs, is made
Amputee restores certain and takes care of oneself and ability to work.Its applicable object is because of disease, traffic accident, industrial accident, movement
The amputee of the reasons such as wound.
Prosthetic hand currently used in the market is simple in structure, is using inconvenience.
Invention content
The technical problem to be solved by the present invention is to overcome the defects of above-mentioned technology, provide a kind of prosthetic hand.
In order to solve the above technical problems, technical solution provided by the invention is a kind of prosthetic hand：Including arm, wrist, hand
The palm, finger composition, the wrist and connection of rolling over, the palm are connected with wrist rotation, and the finger and palm pass through
Tumbler connects, and the lower end of the finger is equipped with moving block, and the moving block is equipped with rotation axis, and the rotation axis, which runs through, to be turned
Motion block, the moving block are equipped with first gear, and the palm is equipped with groove body, and the moving block is placed in groove body, described
Cavity is equipped in palm, the cavity is located on the downside of groove body, and micromotor is fixed in the cavity, the micromotor
Second gear, the second gear and first gear engagement are fixed in drive shaft.
As an improvement, being located at groove body side in the palm is equipped with fixing groove, the fixing groove and rotation axis are rotatably assorted.
As an improvement, the micromotor is micro servo motor.
The advantages of the present invention over the prior art are that：It is driven by micro servo motor and drives second gear rotation,
Second gear drives first gear rotation to realize the rotation of finger, contributes to that prosthetic hand is accurate, stably accomplishes crawl, pinches
It takes and pinches and the actions such as take.
