Description

Swing head wrench

The invention mainly discloses a oscillating head wrench, in particular a oscillating weight wrench which can be easily disassembled and assembled by the body and the oscillating member to improve the turning torque and the structural strength.

Wrench is a must-have hand tool for the industry. Commonly used, such as open-end wrenches and plum wrenches, this traditional wrench takes time in the operation process, so the ratchet wrench and ratchet socket wrench, ratchet wrench and ratchet socket wrench appeared later. More efficient operation time and shorter man-hours than open-end wrenches or wrenches.

However, due to the different working conditions, there are many occasions where obstacles are encountered, so that the wrench can not be effectively turned over due to the obstacle being blocked by the obstacle during the reciprocating movement. For example, the hexagonal head of the bolt provides the ability to rotate every 60 degrees, and the inner hole of the wrench has a twelve-corner shape, providing the ability to pull every 30 degrees. If the obstacle is blocked in the angle limit range in which the wrench reciprocates, it usually causes the work to be locked or relaxed.

Therefore, an angle-adjustable wrench was later designed to utilize a pivotable joint on a ratchet wrench or a ratchet socket wrench to enable the wrench's grip to rotate relative to the ratchet end. When the ratchet end of the plum blossom is connected to the workpiece, the grip of the wrench is angled with the ratchet end by the joint, so that the grip of the wrench can flash over the obstacle, thereby allowing the reciprocating turning operation of the wrench to smoothly run.

The existing adjustable angle wrench uses the joint to achieve the effect of adjusting the angle. Although the problem of being blocked by the obstacle is solved, the first problem is that the design of the wrench joint cannot be disassembled by the user. When the parts of the adjustable angle wrench are damaged, the user cannot disassemble and replace it.

Moreover, the adjustable angle wrench often has poor design at the joint, resulting in poor strength and inability to effectively resist the torsion and shear generated during the turning operation, so it is not possible to advance to the high-strength advanced wrench.
