Abstract
Description
Technical Field
[0001] This utility model relates to the field of tool design technology, and in particular to a pull-rotate hinge pliers. Background Technology
[0002] In food packaging and some automated wire-tying processes, wire twisting is often required. In some low-automation, workshop-style production facilities, traditional wire cutters are still used. The wire is clamped with pliers, and the pliers are turned round and round to tighten it. This is not only labor-intensive but also time-consuming and inefficient. Therefore, it is necessary to design a lightweight and quick tool suitable for small-scale, low-automation applications to replace traditional wire cutters. Summary of the Invention
[0003] The purpose of this utility model is to solve the above-mentioned technical problems and provide a lightweight, quick, compact, and labor-saving pull-and-spindle pliers.
[0004] To achieve the above technical objectives and requirements, the technical solution adopted by this utility model is as follows: a pull-and-spindle clamp, comprising a spiral rod, with a clamp, a pressing slider, and an adjusting bracket sequentially arranged at the front end of the spiral rod. The clamp and the spiral rod are riveted together by pins, and a jaw spring is provided between two opposing clamps. The pressing slider is sleeved on the spiral rod, and the adjusting bracket is threadedly connected to the spiral rod. A pressing handle is provided on the adjusting bracket. A spiral sleeve is sleeved on the spiral rod, and the spiral sleeve and the spiral rod cooperate to form a rotary motion pair. A slider is provided between the spiral rod and the spiral sleeve, and a handle is provided on the spiral sleeve.
[0005] Preferably, the clamping handle and the adjusting bracket are hinged by a pin.
[0006] Preferably, the front end of the clamping handle is provided with an eccentric structure. When the clamping handle is pressed against the center of the screw rod, the eccentric structure is used to push the clamping slider to clamp the clamp.
[0007] Preferably, the slider is disposed within the groove of the outer ring of the screw rod.
[0008] Compared with traditional structures, the advantages of this utility model are: compact structure, the pull-rotor strand clamp is mainly used for stranding steel wire with a diameter of less than 1.0mm. By pulling the spiral sleeve, the spiral rod and the clamps on it are rotated to tighten the steel wire. The operation is easy, quick and labor-saving, reducing labor intensity and improving work efficiency. Attached Figure Description

[0011] The present invention will be further described below.
[0012] See attached document Figure 1 A type of pull-and-spindle clamp includes a helical rod 6. At the front end of the helical rod 6, clamps 1, a clamping slider 3, and an adjusting bracket 4 are sequentially arranged. The clamps 1 are riveted to the helical rod 6 with pins, ensuring that the clamps 1 can swing easily. A jaw spring 2 is arranged between two opposing clamps 1, which can keep the jaws in a normally open state and simultaneously drive the clamping slider 3 to automatically reset. The clamping slider 3 is sleeved on the helical rod 6 and can slide freely. The adjusting bracket 4 is threadedly connected to the helical rod 6, allowing adjustment of the clamping force according to the thickness of the clamped wire. A clamping handle 5 is provided on the adjusting bracket 4. A helical sleeve 7 is sleeved on the helical rod 6, and the helical sleeve 7 and the helical rod 6 cooperate to form a rotary motion pair. A slider 9 is arranged between the helical rod 6 and the helical sleeve 7. A handle 8 is provided on the helical sleeve 7.
[0013] In this preferred embodiment, the clamping handle 5 and the adjusting bracket 4 are hinged by a pin, and the clamping handle 5 can be rotated easily.
[0014] In this preferred embodiment, the front end of the clamping handle 5 is provided with an eccentric structure. When the clamping handle 5 is pressed against the center of the screw rod 6, the eccentric structure pushes the clamping slider 3 to clamp the clamp 1. The eccentric structure can keep the clamping handle 5 in a clamping self-locking state.
[0015] In this preferred embodiment, the slider 9 is disposed within the helical groove of the outer ring of the helical rod 6. When the helical sleeve 7 moves linearly, it drives the slider 9 to move helically within the helical groove. Since the helical sleeve 7 is held in the operator's hand, its rotational freedom is restricted, thus driving the screw 6 to rotate.
[0016] In practice, the operation process of this utility model is as follows:
[0017] 1) With the clamping handle 5 open, align the clamp 1 with the target wire;
[0018] 2) Press down the clamping handle 5 firmly to keep it close to the spiral sleeve 7; the clamping handle 5 can maintain the clamping state under the action of the eccentric structure.
[0019] 3) Hold the handle 8 and pull the spiral sleeve 7 backward. At this time, the clamp 1 will start to rotate. Before the wire is tightened, you can release the handle 8, push the spiral sleeve 7 to rotate and reset along the spiral groove, and then pull the spiral sleeve 7 again to repeat the tightening action.
[0020] 4) After tightening the wire, open the clamping handle 5 and remove the pull-rotor wire clamp.
[0021] The above embodiments of this utility model are merely examples to clearly illustrate this utility model, and are not intended to limit the scope of protection of this utility model. All equivalent technical solutions also fall within the scope of this utility model, and the patent protection scope of this utility model should be defined by each claim.
