Abstract

The invention provides a clamping device with a labor-saving effect, which includes a first clamper and a second clamper, the first clamper includes a first handle and a first jaw, the first The jaw is connected to one end of the first handle, and the second holder includes a second jaw and a second handle. The second jaw is pivotally arranged on the first handle with a first virtual shaft as the center and The first jaw is opposite to each other, and one end of the second handle is pivotally arranged on the second jaw with a second virtual rotating shaft as the center. The distance from the second virtual rotating shaft to the end of the second handle forms a first length, and the second The holder has a top latch arm, and one end of the top latch arm is pivotally arranged on the second handle with a third virtual rotation axis as the center. The distance from the third virtual rotation axis to the second virtual rotation axis forms a second length, and the second length less than 0.19 times the first length.

Description

technical field [0001] The invention mainly relates to a clamping device, especially a clamping device with labor-saving effect. Background technique [0002] Please refer to the "universal pliers" patent case of China Taiwan Patent No. I411498, which discloses a universal pliers comprising a first handle, a fixed pliers head fixed at the front end of the first handle, and a first A pivot pin is pivotally connected to the movable pliers head of the first handle, a second handle is pivotally connected to the movable pliers head by means of a second pivot pin, and a movable pliers head is installed on the first handle and the movable pliers head and The locking unit between the second handles. A drive hole of the movable pliers head for the first shaft pin to pass through has an arc abutting portion, and the locking unit has an elastic member to make the movable pliers head move toward the rear end constantly and make the arc abutting portion constant The moving path of the ...
