Due to the protection of the pin protection mechanism, the chip pins will not be excessively bent or damaged under the action of the impact force.

[0027] In this embodiment, in order to achieve reasonable design, a pin protection mechanism, a material blocking mechanism, a misaligned track and a clearance port A5 for fixing the chip are provided in the middle portion of the misaligned track.
