The pliers are very tight, use a surprising trick to win

The sunset red lbq pair of needle-nose pliers are very tight, and the troubleshooting method is introduced below for your reference only.

Troubleshooting: The mouth of my needle-nose pliers is very tight, and it is very difficult to close the pliers. It requires two hands to open the pliers, which is very laborious and inconvenient to use. For this reason, the specific measures taken by Sunset Red lbq to troubleshoot are:

1. Open the needle-nose pliers → clamp → open → clamp → ┅┅ repeatedly, but the fault still exists.

2. Use a hammer to repeatedly hit both sides of the needle-nose pliers shaft, and then open the needle-nose pliers → clamp → ┅┅ repeatedly, but the fault is not eliminated.

3. Add lubricating oil to both sides of the needle-nose pliers shaft, and then open the needle-nose pliers → clamp → ┅┅ repeatedly, but the fault is not significantly improved.

4. Add 1:3 dilute hydrochloric acid dropwise to both sides of the needle-nose pliers shaft with a glass dropper, and then repeatedly open the needle-nose pliers → clamp → ┅┅ from the gap in the shaft Some brown rust dilute acid solution flowed out, and the fault was finally eliminated.

It turns out that the problem of the tight mouth of the needle-nose pliers was caused by the rust between the shafts.

5. Clean the residual dilute hydrochloric acid on the needle-nose pliers shaft, dry it, and add lubricating oil to the needle-nose pliers shaft. The problem of the needle-nose pliers being tight will be eliminated. Needle-nose pliers are very flexible to use, so you don't have to use two hands to operate them.

Note: The repaired needle-nose pliers with very tight mouth should not be exposed to water. Do not store them in a humid place, but in a dry environment. This will prevent the pliers shaft from rusting again, and then The pliers are tight.
