Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in further detail with reference to the accompanying drawings in conjunction with the following detailed description. It should be understood that the description is intended to be exemplary only, and is not intended to limit the scope of the present invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

As shown in fig. 1-3, the tool for accurately measuring the size of the circumference of a hand provided by the utility model comprises a handle a 1, a middle shaft 3 and a handle B4, wherein the handle a 1 is rotatably connected with the handle B4 through the middle shaft 3, a scale 2 is arranged on the upper surface of the handle a 1, and a pointer 41 attached to the scale 2 is arranged at the top of the handle B4;

the handle A1 and the handle B4 are both provided with a distance adjusting mechanism 5, the distance adjusting mechanism 5 comprises a rod retracting seat 51, a locking bolt 52 and a distance adjusting rod 53, the rod retracting seat 51 is respectively arranged at the far ends of the handle A1 and the handle B4, the inside of the rod retracting seat 51 is movably connected with the distance adjusting rod 53, and the locking bolt 52 for assisting locking penetrates through the joint of the rod retracting seat 51 and the distance adjusting rod 53;

the bottom of two roll adjustment poles 53 is connected with A steel ring respectively and presss from both sides 6 and B steel ring and presss from both sides 7, and the logical inslot of A steel ring clamp 6 and B steel ring clamp 7 is drawn and is passed steel ring 8.

It should be noted that:

1. the handle A1 and the handle B4 are in a scissor-type structure, the staggered radian is the same as that of the scale 2, and the measurement of the circumference of a hand is carried out within the shearing moving range;

2. the inner wall that A steel ring clamp 6 is connected to the one end of steel ring 8, and the inner wall at B steel ring clamp 7 is connected to the other end, and steel ring 8 is the metal component that can buckle, and the steel ring 8 after a section is buckled is held between A steel ring clamp 6 and the B steel ring clamp 7.

In the embodiment, when the size of the hand circumference needs to be measured, the distance between the steel ring 8 and the handle is adjusted by the distance adjusting mechanism 5, the distance adjusting rod 53 is pulled out of the rod retracting seat 51, after the distance is adjusted to the distance suitable for the arm to be placed in the steel ring 8, the locking bolt 52 penetrates through one end of the rod retracting seat 51 and is abutted against the distance adjusting rod 53 to realize locking, a user holds the handle A1 and the handle B4, the two handles rotate through the central shaft 3 to do shearing action to drive the steel ring 8 on the steel ring clamp A6 and the steel ring clamp B7 to be bent and tightened until the arm of the user is attached, and the hand circumference is observed through the pointer 41 on the scale 2;
