The movement structure of the electronic thermometer provided by the present invention is mainly composed of a casing, a movement, and a battery. The characteristic is that when the pressing portion of the casing is pressed by an external force, the pressing portion is A card surface drives the second card surface of the carding portion so that the movement can be removed by the user in the assembly space, thereby enabling the movement to be subjected to the replacement of the battery. The card is limited, and will not be pulled out, resulting in poor contact between the front end of the movement and the broken conductor. The other one can use this feature to repair or replace the movement when repairing the movement. The core reduces damage caused by battery replacement, and it does not cause the movement to be unable to repair or replace the movement due to the carding.本新型所提供一種電子溫度計的機芯卡制結構，主要由一殼體、一機芯、及一電池所組成，其特色係透過一外力按壓該殼體的按壓部時，該按壓部的第一卡制面會帶動卡制部的第二卡制面，以使該機芯能被使用者卸除於該組裝空間，藉此令本新型可於更換該電池時，該機芯能被受限卡制，而且不會被抽出而造成該機芯前端感溫導線接觸不良以及該感溫導線斷裂，另一則於維修該機芯時卻可使用此特點抽出該機芯做維修或更換該機芯，減少因為更換電池而造成的損壞，此外也不會因為卡制而無法抽出該機芯導致無法維修或更換該機芯之兩個目的。
