Eccentric needle-nosed pliers and needle-nosed pliers are two common pliers tools. Their differences, advantages and disadvantages are as follows:

Difference:

1. Different clamping methods: the clamping point of eccentric needle-nosed pliers deviates from the handle axis to a certain extent, which makes the clamping force more concentrated and suitable for clamping small parts; However, the clamping point of needle-nosed pliers is consistent with the handle axis, and the clamping force is evenly distributed, which is suitable for clamping larger parts.

2. Different clamping capacity: because the clamping point of the eccentric needle-nosed pliers deviates from the axis of the handle, the clamping force is more concentrated and can provide greater clamping force; However, the clamping force of needle-nosed pliers is relatively small.

Advantages and disadvantages:

Advantages of eccentric needle-nosed pliers:

1. Large clamping force: Due to the deviation of clamping points, eccentric needle-nosed pliers can provide greater clamping force and are suitable for clamping small parts.

2. Flexible operation: The design of eccentric needle-nosed pliers makes the operation more flexible and can be clamped to some narrow or difficult places.

Disadvantages of eccentric needle-nosed pliers:

1. is not suitable for clamping large parts: due to the deviation of clamping points, the clamping capacity of eccentric needle-nosed pliers is relatively small and it is not suitable for clamping large parts.

2. Not suitable for occasions requiring uniform clamping force: the clamping force of eccentric needle-nosed pliers is concentrated near the clamping point, which is not suitable for occasions requiring uniform clamping force.

Advantages of needle-nosed pliers:

1. Suitable for clamping large parts: Needle-nosed pliers have large clamping capacity and are suitable for clamping large parts.

2. Uniform clamping force: the clamping force distribution of the needle-nosed pliers is uniform, which is suitable for occasions requiring uniform clamping force.

Disadvantages of needle-nosed pliers:

1. The clamping force is relatively small: compared with the eccentric needle-nosed pliers, the clamping force of the needle-nosed pliers is relatively small.

2. The operation is relatively inflexible: the design of needle-nosed pliers makes the operation relatively inflexible, and it may be difficult to clamp in some narrow or difficult places.

According to the specific use requirements, selecting the appropriate pliers can improve the work efficiency and effect.
