Embodiment Construction

[0015] Such as figure 1 with figure 2 As shown, the anti-rotational self-clamping linkage pliers include a front clamping mechanism for clamping the shaft, a rear clamping mechanism for clamping a fixing member screwed on the shaft, and the front clamping mechanism and the rear clamping mechanism There is a connecting mechanism connecting the two and enabling them to perform one-way relative rotation. The connecting mechanism can extend axially, and its maximum extending distance is greater than the axial length of the fixing piece.

[0016] The front clamping mechanism in the present invention includes a front clamping inner tube 1 and a front clamping outer tube 2 which are nested together and can rotate relatively. Between the front clamping inner tube 1 and the front clamping outer tube 2, there is a The rotation connection between the two is realized by installing bearings. The middle ring of the front clamping inner cylinder 1 is equipped with three front clamping bloc...

Abstract

The invention discloses a self-clamping linkage clamp capable of preventing shaft rotation. The self-clamping linkage clamp capable of preventing shaft rotation comprises a front clamping mechanism used for clamping a shaft and a rear clamping mechanism used for clamping a fixing piece installed on the shaft in a screwed mode. A connecting mechanism is arranged between the front clamping mechanism and the rear clamping mechanism, and the front clamping mechanism and the rear clamping mechanism are connected and can rotate relatively in one direction through the connecting mechanism. The connecting mechanism can stretch in the axial direction, and the maximum stretching distance of the connecting mechanism is larger than the axial length of the fixing piece. According to the self-clamping linkage clamp capable of preventing shaft rotation, through the arrangement of the front clamping mechanism, the rear clamping mechanism and the connecting mechanism, the purpose of preventing the shaft from rotating when the fixing piece on the shaft is dismounted is achieved, oil leakage and even falling of internal connecting lines caused by shaft rotation are prevented, and using is convenient. After dismounting is completed, a handle is rotated so as to rotate a stop lever out of a clamping groove, an auxiliary handle rebounds automatically under the action of a return spring, the clamped piece is loosened, and thus the clamp can be dismounted from the shaft, and operation is easy and convenient.

Description

technical field [0001] The invention relates to an anti-axis rotation self-clamping linkage pliers. Background technique [0002] At present, a large number of oil-containing equipment is used in power equipment. The lead-out parts of the oil-containing equipment, such as the bushing lead shaft, will easily cause the rotation of the lead shaft during the process of removing the external nut. In severe cases, oil leakage or even internal connection wires will fall off. . Therefore it is necessary to design a kind of nut removal tool that can effectively prevent the lead shaft from rotating when the nut is removed. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an anti-shaft rotation self-clamping linkage pliers that prevents the shaft from rotating when the fixing part on the shaft is removed. [0004] In order to solve the above-mentioned technical problems, the present invention includes a front clamping mech...
