Description

[Detailed Description of the Invention] Industrial Field of Use This invention relates to a hand that has an elastic rotating body with granular protrusions pivotally supported at its tip.

Conventional technology Son's hand, which has a finger shape on the tip of a bamboo rod, is often used as a tool for scratching the back where the fingertips cannot reach. There are no tools designed to contact the area.

Problems that the invention aims to solve: In the hands of bamboo rods, the fingers at the tips must be moved back and forth while touching the itchy part of the back, which is time-consuming, and because the bamboo rods are straight. Depending on the part of the back, the arm that grips the bamboo rod must be rotated upwards of the back in a reciprocating motion, which is time-consuming and tiring.

In order to solve such problems, the present invention has a hinge in the middle part of the tube so that it can be bent, and a small motor is installed inside the tip of the pipe shaft, and the rotating shaft of the small motor is connected to the outer circumferential surface. It is a grandchild's hand that has an elastic rotating body with many granular protrusions protruding from it fixed on it, and while turning the switch of the battery inserted into the rear end of the tube shaft ON and OFF, the body surface is rotated while rotating the elastic rotating body with granular protrusions. It is characterized in that it can save the effort of bringing it into contact with an itchy area and operating it back and forth.

Means for Solving the Problems The configuration of the present invention will be described below with reference to the drawings.

A partition plate 2 is fixed inside the first tube shaft 1a near the tip, a small motor 3 is fitted therein, a rotating shaft 4 of the small motor 3 is supported by a bearing 5, and a cap 6 is attached to the first tube shaft 1a.
After fitting the end of the tube shaft 1a and inserting the thrust bearing 7 into the rotating shaft 4 protruding from the cap 6, an elastic rotating body 9 made of an elastic material such as rubber and having a large number of granular protrusions 8 protruding from its outer circumferential surface is attached. The concave metal fitting 12 and the convex metal fitting 13 are attached to the tip of the second tube shaft 1b protruding from the battery insertion tube 11 and the rear end of the first tube shaft 1a with bolt pins 14. Both ends of the pivoted hinge are fitted and tightened, and several sets of locking grooves 15 are provided on the circumferential surface of the tip of the convex metal fitting 13 to form the concave metal fitting 1.
engaging with the spring-equipped locking ball 16 on the inner surface of 2;
A (+) terminal 18 is secured to the center of the partition plate 17 in the battery insertion tube 11, and a (-) terminal 19 is secured to the end thereof, and the (-) terminal is secured inside the switch chamber 21 into which the switch button 20 is fitted. 19 and battery insertion tube 1
A contactor 22 is arranged from the rear end of 1 to the switch chamber 21, a battery 23 is inserted into the battery insertion tube 11, a cap 25 with a spring terminal 24 is screwed on, and the (+) Terminal 18 and (-)
The cord 26 connected to the terminal 19 is connected to the first tube shaft 1a.
It constitutes a rotary grandchild's hand 27 connected to the terminal of the small motor 3 inside.

Effect: When the rotary grandchild's hand 27 grasps the battery insertion tube 11 with one hand and slides the switch button 20 forward, the contact 22 and the (-) terminal 19 connect and the small battery inside the first tube shaft 1a connects. The motor 3 is energized, and the elastic rotating body 9 rotates together with the rotating shaft 4. Then, apply the elastic rotating body 9 to the itchy area on the body surface.
The granular protrusions 8 on the outer peripheral surface of the elastic rotating body 9
It relieves itching by contact resistance against the body surface. The first tube shaft 1a and the second tube shaft 1b are connected by a hinge in which a concave metal fitting 12 and a convex metal fitting 13 are pivotally connected with a bolt pin 14. In order to engage the locking ball 16 with a spring inside the metal fitting 12, the first tube shaft 1a and the second tube shaft 1b are freely bent into a square shape. The elastic rotating body 9 can be easily brought into contact with the back region without bending the shaft and lifting the hand upward. The elastic rotating body 9 is made of an elastic material such as rubber or urethane, so that it can protect the skin surface when it comes into contact with the body surface. It has the above-mentioned remarkable effects, such as being able to easily remove itchiness by just lightly touching the body surface with 9.
