Technical Field

The invention relates to locking pliers with a lengthened handle, and belongs to the technical field of locking pliers.

Background

The locking pliers are used for achieving the shearing technical function of metal materials or hard materials, but the locking pliers are technically arranged at the present stage and belong to the technical structure of a fixed structural formula, and the common locking pliers cannot achieve the shearing function well when meeting the space which is difficult to shear or has a narrow environment in the subsequent use.

Disclosure of Invention

Aiming at the problems in the prior art, the invention provides the locking pliers with the extendable handles, which have good shearing force using arrangement, the locking pliers are structurally provided with a rotary supporting seat, have symmetrical rotating and supporting functions, and the movable handles are provided with the extension bars, so that the locking pliers are beneficial to having the labor-saving function of lever technology in subsequent use and have the using technical functions in various environments.

In order to achieve the purpose, the invention is realized by the following technical scheme: the utility model provides a locking pliers of handle can extend, includes rotary support seat, activity pincers one, activity pincers two, compression spring, activity bracing piece one and activity bracing piece two, the upper portion fixedly connected with activity pincers one of a side surface of rotary support seat, the lower part fixedly connected with activity pincers two of a side surface of rotary support seat, activity bracing piece two connect activity pincers two through the upper portion of fixed connection at rotary support seat opposite side surface, activity bracing piece one connect activity pincers one through the sub-unit connection of fixed connection at rotary support seat opposite side surface, activity bracing piece one and activity bracing piece two pass through compression spring and connect near the relative surface in one side of rotary support seat.

And a first fixing groove and a second fixing groove are symmetrically arranged on the surface of one side, opposite to the second supporting rod, of the first supporting rod and are fixedly connected through compression springs.

One end of the first supporting rod, which is far away from the rotary supporting seat, is provided with a first threaded hole site, and the first threaded hole site is in threaded connection with a first extension rod.

And one end of the second support rod, which is far away from the rotary support seat, is provided with a threaded hole position II, and the threaded hole position II is in threaded connection with a second extension rod.

In conclusion, the locking pliers with the extensible handles have good shearing force, the locking pliers are structurally provided with the rotary supporting seat, the rotary supporting seat has symmetrical rotating and supporting functions, the movable handles are provided with the extension rod, the locking pliers are beneficial to having labor-saving effect of lever technology in subsequent use, and have technical functions in various environments.
