Two-stage pincers as hand-operated tools, especially multifunctional wrenches automatically switching between two stages and having a large-opening jaw and a high clamping force, comprising: a first main structure (1), a second main structure (2), a handle (3), a pawl (4), a first pin (5), a second pin (6), a first connecting rod (7), a second connecting rod (8), a first stop nut (9), a second stop nut (10), a first preloaded spring (11), a second preloaded spring (12), a supporting spring (13), a small pin (15), a second small pin (14), a third pin (18), a fourth pin (16) and a fifth pin (17). The two-stage pincers overcome problems of the existing hand-operated tools, i.e. wide varieties, inconvenience to carry and low efficiency.

An electrosurgical device kit includes an elongate first member, an elongate second member disposed adjacent to the first member, the second member being at least movably coupled to the first member, a first electrode head removably attachable to the first member, a second electrode head removably attachable to the first member, and a third electrode head coupled to the second member. The first, second, and third electrode heads are configured to apply a current to a tissue, the first and second electrode heads being non-identical.

A dual compression and distraction tool for surgical operations, the tool including a first arm having a first pivot axis, a second pivot axis, a first lever, and a first dual purpose jaw, a second arm having a third pivot axis, a fourth pivot axis, a second lever, and a second dual purpose jaw, wherein, in a first position, the first arm is pivotably connected to the second arm such that the first pivot axis is merged with the third pivot axis, to form an distraction tool, and wherein, in a second position, the first arm is pivotably connected to the second arm such that the second pivot axis is merged with the fourth pivot axis, to form a compression tool.

An apparatus and method to a folding and a partially rotational device, comprising: stabilizing the frame holder of the device for the axis on which a partially rotational part rotates; spindle locking the partial rotation at two-ends using a spindle with screws at each-end of the spindle; defining the two-ends for the rotation with two or more stop pins; allowing the rotation with two or more compression springs; installing and cleaning the compression springs using a wiper; wherein tension of the rotation is adjusted by placement of one or more of the wiper or compression spring length.

A pliers hanger is provided, configured to restrict a pliers. The pliers includes two handling bodies pivotally connected with each other. Each of the two handling bodies has a holding portion and a clamping portion at opposite ends thereof. The pliers hanger includes a main body, a sleeve portion and a restricting assembly. The main body includes a hanging portion. The sleeve portion is disposed on the main body. The restricting assembly includes a cable tie and a through hole. One of the cable tie and the through hole is disposed on the main body, and the other is disposed on the sleeve portion. The cable tie has a first engaging portion, and the cable tie is configured to be wound around the pliers and between the holding portions of the two handling bodies and restrictedly engaged in the through hole.
