Abstract

The invention discloses a V-type bionic tool hand comprising a handle with a fixed paw, a worm gear, a movable paw with a worm rod, a wedge form slide block, a spring bolt, a stop bolt, a spring hook, a cylindrical slide rail, a slideway hole, a spring and a stop block; the wedge form slide block is positioned on a clamp surface of the fixed paw; the wedge form slide block clamp surface is a zigzag slope; the wedge form slide block and the movable paw form a V-shape port. The V-shape port can be applied to operation of a nut and a tubular object in a larger size; combined with the wedge form slide block structure design, the wrench can have similar ratchet function, i.e., when the nut or tubular object are screwed, the wrench needs not to exit from the nut or tubular object, and can directly return and re-screw; the wedge form slide block structure design allows the force bearing area of the screwed object to be bigger, various force bearing directions are realized, and force bearing is more uniform; the appearance damages of the screwed object can be smaller, and nuts and tubular objects that cannot be unscrewed by any conventional wrench can be unscrewed by the V-type bionic tool hand.

Description

technical field

[0001] The invention relates to a manual tool, in particular to a V-shaped bionic tool hand. Background technique

[0002] Traditional wrenches can only screw hexagonal nuts and square nuts, but cannot screw tubular objects and nuts of other shapes. When the nut is rusted, due to the insufficient force of the wrench, the nut cannot be unscrewed, and there is a possibility of slippage, and the shape of the nut will be damaged. Moreover, after the traditional wrench has finished screwing the nut once, the reset operation is difficult, and it is often necessary to take the wrench out of the nut, then return to the nut, and repeat the operation of screwing the nut. In addition, when the traditional wrench is twisted, the worm gear needs to be repeatedly adjusted to find the opening distance of the wrench, and the wrench is also very easy to loosen during repeated clamping, which brings great difficulty to the operation. The pipe wrench is mainly used for twisti...
