Bind type finger traction device

Abstract

The invention discloses a bind type finger traction device. The device includes a support frame and a servo motor; a first pin is fixed on the support frame, an output shaft of the servo motor fixes the rear ends of a sixth gear and a first connection rod, the first pin is rotatably connected with the rear ends of a first twin-wheel and a second connection rod, and a second pin is rotatably connected with the right end of a fifth connection rod, the front end of the second connection rod and the rear ends of a second twin-wheel and a sixth connection rod; a fifth pin is rotatably connected with the front end of the first pin, the left end of the fifth connection rod and the rear end of a fourth connection rod and fixedly connected with the rear ends of a fifth gear and the fourth connection rod; the sixth gear is meshed with a first gear of the first twin-wheel, the fifth gear is meshed with a second gear of the second twin-wheel, and a first belt pulley of the first twin-wheel and a second belt pulley of the second twin-wheel form a belt transmission; a third pin is rotatably connected with the right end of a seventh connection rod and the right end of a third connection rod, thefront end of a fourth connection rod and a third gear are fixed, a fourth pin is rotatably connected with the left end of the third connection rod, and the rear end of a finger swing rod and a fourthgear are fixed.

Description

technical field [0001] The invention relates to a finger pulling device, in particular to a binding finger pulling device. Background technique [0002] my country is a country with a large population. Every year, there are a large number of people with finger dysfunction caused by hand trauma, brain trauma, and cerebrovascular diseases, and different degrees of finger motor dysfunction occur. Moreover, the hand is one of the important organs of the human body. Daily life and daily work need to be realized by hand. If the current finger traction training device is driven by a single motor, the movement trajectory of the traction finger is too simple, and the recovery of finger functions is not improved. If multi-motor traction is used, the control calculation, mechanical The structures are all complicated, prone to breakdowns, and cause secondary injuries to users. [0003] This application adopts a single servo motor drive, through the two-stage linkage mechanism transmissio...
