Clamping device capable of rapidly adjusting clamping force

Abstract

The invention discloses a clamping device capable of rapidly adjusting clamping force. The clamping device comprises a first holder and a second holder. The first holder comprises a first holding handle and a first clamping jaw which are mutually fixedly connected; the first holding handle is provided with a sliding section and an adjusting part; one end of the adjusting part is screwed to the first holding handle in the axial direction of a virtual rotating axis and extends to the sliding section; an operating portion is arranged at one end, far from the first holding handle, of the adjusting part; the transverse width of the operating portion is smaller than that of the sliding section; a through hole is formed in the operating portion of the adjusting part; the through hole penetrates through the two sides of the operating portion of the adjusting part; the second holder is connected to the first holder and comprises a push-pull part; one end of the push-pull part can be relatively slidably arranged on the sliding section of the first holding handle and abuts against the adjusting part. By means of the adjusting part, an operating rod can be inserted so as to facilitate bare-handed rotation, and the size is not too large.

Description

technical field [0001] The invention mainly discloses a clamping device, especially a clamping device for quickly adjusting the clamping force. Background technique [0002] Please refer to the "Improved Universal Pliers" patent case of Taiwan Patent Publication No. 239357, which is an improved universal pliers, which forms a long and wide protrusion at the jaw, and the tooth shape formed inside the protrusion , one row is inclined toward one side, and the other row is inclined toward the other side. When clamping a metal pipe with two tooth shapes with different inclination directions, it has better performance and is not easy to loosen. In addition, a sleeve with a screw hole is provided inside the side of the back grip, which is convenient for bolts to be screwed into the inside of the sleeve. Because the sleeve has an appropriate reinforcing effect, it can prevent the back grip from being deformed, and Allows the bolt to turn inside the sleeve. [0003] However, the ab...

Problems solved by technology

[0003] However, the above-mentioned universal pliers adjust the tightness of the jaws by turning the bolts, and must be adjusted before the universal pliers clamp the metal pipe. If the universal pliers clamp the metal pipe, the front jaws push against The front grip drives the connecting rod to push against the bolt, so that the user can no longer turn the bolt by hand to adjust the tightness of the jaws. To adjust the tightness, the universal pliers must first be released and the bolt adjusted before clamping the metal round pipe again. trouble

[0004] Furthermore, because the bolt head of the above-mentioned universal pliers bolt is bulky, it is easy to get stuck in other objects or interfere with the movement of the user's hand during use, causing inconvenience in use.
