Test device and rotation module thereof

A test device, comprising:

• a housing;
• a rotation module, disposed in the housing, wherein the rotation module comprises:
• a rotation body, comprising:
• a shaft, pivoted in the housing;
• a position limiting element, telescoped on the shaft;
• a reciprocation element, telescoped on the shaft, and the reciprocation element having a groove;
• and
• a rotation element, engaging with the shaft, and the rotation element being located between the position limiting element and the reciprocation element;
• and
• a driving element, slideably disposed in the housing and coupled to the groove;
• and
• a carrying cartridge, detachably disposed on the shaft, wherein the carrying cartridge has a plurality of perforated grooves;
• and
• a push rod, connecting the driving element, and the push rod being aligned to any one of the perforated grooves,
• wherein when the driving element moves back and forth towards a first direction and an opposite direction of the first direction, the driving element drives the reciprocation element to rotate back and forth relative to the position limiting element through the groove, and the rotation element is pushed by the reciprocation element to rotate along a rotation direction relative to the position limiting element for driving the shaft to rotate along the rotation direction and driving the carrying cartridge to rotate along the rotation direction together with the shaft, and the push rod is aligned to a next one of the perforated grooves.

A test device, comprising:

• a housing;
• a rotation body, comprising:
• a shaft, pivoted in the housing;
• a position limiting element, telescoped on the shaft and non-rotatably disposed in the housing;
• a reciprocation element, telescoped on the shaft, and the reciprocation element having a groove;
• and
• a rotation element, engaging with the shaft, wherein the rotation element engages with the reciprocation element through a first ratchet wheel structure, and the rotation element engages with the position limiting element through a second ratchet wheel structure, and the rotation element is limited to unidirectionally rotate by the first ratchet wheel structure and the second ratchet wheel structure;
• a driving element, slideably disposed in the housing and coupled to the groove;
• a carrying cartridge, detachably disposed on the shaft, wherein the carrying cartridge has a plurality of perforated grooves;
• and
• a push rod, connecting the driving element;
• wherein when the driving element moves back and forth towards a direction, the driving element drives the reciprocation element to move back and forth through the groove for driving the rotation element to unidirectionally rotate while driving the shaft and the carrying cartridge to unidirectionally rotate.
