During the use of HELL series engraving styli, high-frequency engraving operations can cause slight misalignment of the aluminum needle handle, leading to tight adhesion with the needle installation position of the engraving head. If a traditional needle puller is used for removal under these circumstances, the force will be directly applied to the installation column, which can easily cause deformation or even breakage.

Addressing this pain point, Litian Century conducted in-depth research into customer needs and developed a new type of needle puller. By optimizing the operational principle and leveraging mechanical structural design, this product precisely positions the puller's insertion claws at the base of the electromechanical engraving needle, transferring the point of force application during removal. This improvement ensures that the installation column remains completely free from external force throughout the removal process, fundamentally resolving the issue of deformation or breakage of the installation column caused by uneven force distribution with traditional needle pullers.

Throughout, Litian Century has remained focused on addressing customers' practical challenges, delivering more reliable solutions through continuous technological innovation and product optimization. This enables customers to tangibly experience the practical value brought by product upgrades.
