Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to a crimping tool used for fastening an optical fiber or a conductive wire to an object to be crimped.

2. Description of the Related Art Conventional crimping tools include a portable type and a stationary type. The portable crimping tool has a pliers shape, and as shown in FIG. 4, one end of a pair of operation handles 1 and 2 is pivotally connected to each other so as to be openable and closable, and a crimping portion 4 is provided near the pivotal portion 3, The handle 1 and 2 are clamped with one hand and a closing force is applied to perform crimping.

The stationary type is used when a large crimping force, which is difficult with manual operation, is required. As shown in FIG. 5, a single operation handle 6 and a crimping portion 7 operated by the single operation handle 6 are mounted on the installation base 5. Are configured.

Problems to be Solved by the Invention As described above, the portable type can be easily carried by being carried to the work site, but has a drawback that it cannot quickly respond to a crimping object requiring a large crimping force, while the stationary type is sufficient. However, it is not suitable for on-site work because it is heavy and large, and it is not suitable for field work.While accepting these inconveniences, it is necessary to have both a portable type and a stationary type. It is in a situation that does not happen.

Means for Solving Problems The present invention was devised to effectively deal with the above inconvenience, and as a means therefor, an installation pedestal and an extension lever were prepared as an attachment for the above portable crimping tool. , The lower surface of the rear end of one of the operating handles extends while abutting it on the upper surface of the installation pedestal, and this operating handle can be attached to and detached from the installation pedestal by screws through the mounting holes provided in the handle , And the end of the extension lever is detachably attached to the rear end of the other operation handle through the screwing means and extends in the extension direction of the operation handle to switch between the stationary type and the portable type. It is designed to be used properly.

Action That is, the extension lever can be unscrewed, the installation base can be unscrewed, and both attachments can be removed to use as a portable type, or both attachments can be carried and used for each operation lever as necessary. By screwing and screwing, it can be easily converted and used as a stationary type, and one crimping tool can appropriately and quickly respond to crimping objects having different crimping forces.

In addition, the crimping tool can be stably supported on the pedestal and requires a large crimping force by firmly tightening it with screws while extending the lower surface of the rear end of one operation handle while abutting it on the upper surface of the installation pedestal. The stationary crimping work can be properly performed with a simple structure without causing rattling or tilting of the crimping tool in cooperation with the one-handed pushing operation of the other operation handle screwed with the extension lever.

Embodiment FIG. 1 to FIG. 3 show an embodiment of a crimping tool according to the present invention.

As shown in the figure, the crimping tool is an installation pedestal consisting of a crimping tool body 11, an extension lever 12 as an attachment, and a flat plate.
13 is provided.

The crimping tool main body 11 has a pair of pliers-type operation handles 14 and 15 of substantially equal length in which front ends thereof are pivotally connected to each other, and a crimping jig is incorporated inside the pivoting portion 22 and the crimping portion 16 is provided between the front ends of the handles. Are configured.

The mounting pedestal 13 is removably attached to one of the operation handles 14 and 15 and the extension lever 12 is detachably attached to the other one 14.

The extension lever 12 is an attachment that extends the effective length of the operation handle 14, and a female screw hole 17 is provided at the rear end terminal of the operation handle 14 and a male screw 18 is provided at the front end terminal of the extension lever 12.
The extension lever 12 is attached to the operation handle 14 by screwing the male screw 18 into the female screw hole 17 and can be detached by releasing the screwing. The extension lever 12 is extended in the extension direction of the operation handle 14, that is, the axial direction by the above-mentioned screwing.

Further, the installation base 13 is an attachment for stably installing the crimping tool main body 11 to which the extension lever 12 is attached on the work table, and has an attachment hole 19 which vertically penetrates the operation handle 15.
A plurality of female screw holes 20 are provided in the mounting pedestal 13, and the rear surface of the rear end of the operation handle 15 is extended while being abutted on the upper surface of the mounting pedestal 13, and the mounting hole 19 is attached to the female screw hole 20 at the abutting portion.
Operation handle 15 by screwing male screw 21 through
The mounting pedestal 13 is firmly fastened and the male screw 21 is loosened so that it can be removed.

Both the extension lever 12 and the installation pedestal 13 are attached to the respective operation handles 14 and 15 by the above-mentioned screw attachment means.

The front ends of the operation handles 14 and 15 having the crimped portion 16 are projected from the front end of the installation pedestal 13, and the lower surface of this front end matches the level of the lower surface of the installation pedestal 13 as shown in FIG. As a result, the installation pedestal 13 and the lower surface of the lever front end are seated at the same time, so that the tool can be stably installed over the entire tool length.

Effect of the Invention According to the present invention, since the installation pedestal and the extension lever can be attached / detached via the screw attachment means, the extension lever and the installation pedestal are always unscrewed and the screw tightening is performed, and the crimping tool main body is released. Serving as a portable crimping tool that requires only a relatively slight crimping force,
If the object requires a relatively large pressure,
It extends on the upper surface of the installation pedestal while being attached to the lower surface of the rear end of one operation handle to firmly tighten the same part with screws, and the end of the extension lever is screwed to the end of the other operation lever. It is possible to respond immediately by extending it in the extension direction of the operating lever, and one crimping tool can be switched appropriately between screwing and releasing the extension lever, and screwing and releasing the installation pedestal to switch between the portable type and the stationary type. It can be used for both purposes, and effective crimping can be performed in each usage pattern.

Also, one operation handle of the crimping tool extends while the lower surface of the operating handle is attached to the upper surface of the installation pedestal, and the attached portion is firmly tightened with a screw, so that the crimping tool can be supported extremely stably on the pedestal, and a large crimping force For an object that requires a joint, the structure is simplified and the stationary crimping work is properly performed in cooperation with the one-handed pushing operation of the other operation handle screwed with the extension lever, without causing the crimping tool to play or tilt. I can carry it out.
