Problems solved by technology

[0003] The problem to be solved by the present invention is to solve the problems that the finger length is not enough and the fingertip strength is too small that people encounter in the process of daily life, study and work, and at the same time overcome the inconvenient use of existing sticks, rods and other mechanisms. Problems, for example, the finger extension mechanism adopts a finger cuff structure, and the rotating joint is located at the joint of the human finger, which not only ensures the flexibility of the finger, but also conveniently lengthens the length of the finger and increases the flexibility of the fingertip. strength

Embodiment Construction

[0021] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0022] Finger extension booster mechanism, it is made up of movable part finger cot 1, fixed part handle 3, two booster part power cranks 5 and connecting rod 7, connecting part pin 2, pin 4, pin 6, pin 8. Connections between parts:

[0023] Finger cot 1 and handle 3 are connected by pin 2, power crank 5 and handle 3 are connected by pin 4, connecting rod 7 and power crank 5 are also connected by pin 6, finger cot 1 and connecting rod 7 are connected by pin 8, finger cot 1 Rotate around pin 2 and pin 8, power crank 5 rotate around pin 4, and connecting rod 7 rotate around pin 6 and pin 8.

[0024] The finger cot 1 is a cylindrical cover, the inside is hollow, slightly thicker than a human finger, and the finger can be inserted. The front end of fingertip can be made into multiple shapes as required, such as a scalpel, a barber comb, etc. The outer surface of the fi...

Abstract

The invention discloses a finger extension mechanism, which is composed of a finger cot (1), a handle (3), a power crank (5), a connecting rod (7), and pins (2, 4, 6, 8). Solve the flexibility of the fingers, and conveniently lengthen the length of the fingers and the strength of the fingertips. Finger cot (1) and handle (3) are connected by pin (2), power crank (5) and handle (3) are connected by pin (4), connecting rod (7) and power crank (5) are also connected by pin (6 ) connection, finger cot (1) and connecting rod (7) are connected by pin (8), finger cot (1) rotates around pin (2) and pin (8), power crank (5) rotates around pin (4), The link (7) turns around the pins (6) and (8). By changing the shape of the short end of the fingertip - scalpel, hair comb, etc., it can be conveniently applied in medical, toy and other fields.

Description

technical field [0001] The present invention relates to a finger lengthening and strengthening mechanism, more specifically, it relates to a mechanism for extending human finger functions and increasing fingertip strength. Background technique [0002] In traditional use, people usually use sticks, rods and other objects that are independent of human fingers to reach the range that cannot be reached by the length of human fingers by holding them. Usually, this method is often very inconvenient to use and requires other fingers. However, there is no mechanism that can be ingeniously combined with people's fingers, so that when people's fingers are lengthened, the strength of the fingertips is increased without losing the flexibility of the fingers. Contents of the invention [0003] The problem to be solved by the present invention is to solve the problems that the finger length is not enough and the fingertip strength is too small that people encounter in the process of da...
