The present disclosure relates to a switching device and a 3D printing apparatus. The switching device includes a rack, an extrusion assembly, a pushing assembly and a driving assembly. The extrusion assembly is connected to the rack and includes a driving roller and a first pressing wheel and a second pressing wheel located on a circumferential outer side of the driving roller. Transport channels allowing consumables to pass are formed between the driving roller and the first pressing wheel and between the driving roller and the second pressing wheel for passing a consumable. The driving assembly and the pushing assembly are connected to the rack; the pushing assembly includes a pushing portion, and the pushing portion is capable of pushing a target consumable to move relative to driving roller to a preset position corresponding to the target consumable under a drive of the driving assembly, so as to restrict the target consumable from moving.

Provided is a strain sensor including a fixing plate and a strain gauge. The fixing plate includes a first supporting part and a second supporting part flexibly connected to the first supporting part. The present application is advantageous in that a strain sensor with a simple structure, high reliability and high sensitivity is provided. The horizontal status of a contact surface may be detected by a little amount of deformation, and the flexible fixing plate can provide a buffer for the equipment to prevent damages due to direct impact.
