Embodiment 2

[0031] The specific embodiment 2 of the screw screwing device of the present invention, the difference between this embodiment and the above-mentioned embodiment is only that: the above-mentioned rotating shaft and the eccentric wheel rotate and cooperate, at this time, no power input section is provided on the rotating shaft, and a rotating shaft is provided on the eccentric wheel in addition. The handle drives the eccentric wheel to rotate by turning the handle.

[0032]In other embodiments, the above-mentioned through hole may not be provided, and the screw rod is only clamped through the cooperation of the first clamping part and the second clamping surface. The second clamping part cooperates with the second clamping surface to clamp the screw rod; the above-mentioned eccentric wheel is a kind of cam. In other embodiments, the eccentric wheel can be other cams that meet the requirements of the clamping screw rod. Of course, the above-mentioned second clamping member can al...

Abstract

The invention relates to the field of screw twisting tools, in particular to a screw twisting device. The screw twisting device comprises a first clamping component, wherein the first clamping component is rotationally assembled with a second clamping component through a rotating shaft; a hook structure matched with a screw is arranged on the first clamping component; a first clamping surface is arranged on the hook structure; a second clamping surface is arranged on the second clamping component; the first clamping component and the second clamping component are matched, so that the first clamping surface and the second clamping surface clam the screw when the second clamping component is rotated to a set position. Compared with the conventional screw twisting device, the screw twisting device provided by the invention does not need to tap the screw, is convenient to operate and high in screw removing efficiency, and solves the problems that the conventional decapitated bolt removing structure is inconvenient to operate and is low in screw removing efficiency.

Description

technical field [0001] The invention relates to the field of screw screwing tooling, in particular to a screw screwing device. Background technique [0002] In mechanical equipment, some bolt heads and screw rods are often disconnected during the bolt removal process, and the screw rod is difficult to take out. In the prior art, the broken bolts are taken out by a bolt take-out device. [0003] For example, a Chinese patent with the announcement number CN202707746U and the announcement date of 2013.01.30 discloses a structure for taking out a broken bolt, including a broken bolt threaded in the connecting piece. There are small bolts connected to the internal thread of the threaded hole, and the thread direction of the threaded hole is opposite to that of the dead bolt. Use a wrench to hold the small bolt and screw it into the threaded hole. Since the thread direction in the threaded hole is opposite to that of the broken bolt, the threaded rod of the broken bolt is slowly ...
