Description

[Detailed Description of the Invention] This invention relates to a clamping tool that does not require consideration of directionality when clamping paper, etc., and can clamp paper or the like with a simple operation.

To explain with reference to the drawings, the upper and lower clamping plates 1.2 are provided with upper and lower clamping edges 3, 4 on the entire periphery of the upper and lower clamping plates 1.2 in the form of a disc.
2, an upper pressing plate section 5 and an upper clamping plate 1 are connected to each other via the lower clamping plate 2 and the central connecting can 11, and several consecutive connecting cans 1
A lower pressing plate part 6 is provided which is connected to the lower pressing plate part 3 via the upper pressing plate part 3, and the central connecting pin 11 of the lower holding plate 2 and the upper pressing plate part 5 is inserted through the central hole 12 of the upper holding plate 1, and further the upper holding plate 1 Several consecutive pins 13 of the lower pressing plate portion 6 are inserted through several insertion holes 14 of the lower clamping plate 2, and a spring 15 is fitted onto the connecting pins 13.

The disc-shaped upper and lower holding plates 1 and 2 are provided with an inwardly directed upper and lower bent portion 7.8 with the periphery directed inward, as well as an upper and lower center recessed portion 9.10, and an upper pressing plate portion 5.6. is the upper and lower center recessed part 9
．． It operates stably by moving up and down within 10, and the upper central concave portion 9 and the upper pressing plate portion 5 have a patterned shape.

In addition, a magnet plate 16 is fixed to the lower pressing plate portion 6 so as to attract metal products, and an annular body 18 made of synthetic resin or the like is provided with a large number of small protrusions 17 on the entire inner periphery of the lower holding plate 2. An elastic annular body 19 made of rubber or the like into which small protrusions 17 bite is provided on the entire inner peripheral edge of the upper clamping plate 1 to prevent the clamped article 20 such as paper from coming off when clamped.

This invention has the above-mentioned configuration, and the upper and lower clamping edges 3.4 are provided on the entire periphery of the disc-shaped upper and lower clamping plates 1.2, and the lower clamping plate 2 and the central Continuous installation 1
An upper pressing plate part 5 and an upper holding plate 1 are provided in series with each other via 1, and a lower pressing plate part 6 is provided in series with each other via several continuous links 13.
In addition, the central connecting pin 11 of the lower holding plate 2 and the upper pressing plate part 5 is inserted through the central hole 12 of the upper holding plate 1, and the several connecting pins 13 of the upper holding plate 1 and the lower pressing plate part 6 are inserted through the central hole 12 of the upper holding plate 1. By inserting the several insertion holes 14 of the lower clamping plate 2 and fitting the spring 15 to the outer part of the connecting pin 13, the upper and lower clamping plate parts 5°60 are pressed by the fingertips, and the upper and lower clamping plates 1°2 are pressed. The upper and lower clamping edges 3 and 4 are detached, and as the clamping pressure by the fingertips is released, the spring 15 is actuated to release the upper and lower clamping edges 3.4 of the upper and lower clamping plates 1.2.
are automatically joined together, and the clamped item such as paper can be clamped by the upper and lower clamping edges 3.4 provided on the entire periphery of the upper and lower clamping plates 1.2, which is extremely convenient for use, Board 1.2
This can be done by binding all the way around the entire circumference, and there is no need to consider the direction when clamping, making it easy to use.

Moreover, it has a simple structure, is strong, and can be held securely, and has many practical effects.
