摘要： A clutch claw applied to a clutch structure having a rotating shaft includes a claw portion, a base portion and at least two elastic portions. The base portion is opposite to the claw portion and has a peripheral edge. The claw portion and the base portion are coaxially disposed on the rotating shaft. Each elastic portion is at least partly disposed around part of the claw portion to provide elastic force. Each elastic portion has a first end and a second end. The first end is connected with the base portion and extended from the peripheral edge, the second end is connected with the claw portion, and there is at least one bent section between the first end and the second end. Therefore, the collision damage is prevented, and the impact and friction generated when the clutch claw is instantaneously rotated is avoided, thereby achieving the advantage of reducing noise.

摘要： A roller structure is disclosed and includes at least one roller unit. The roller unit includes a base, an elastic portion, a supporting portion and a rotating wheel. The base is configured to detachably assemble the roller unit on an accommodation seat. The base includes a first lateral edge. The elastic portion is disposed on the base and connected with the first lateral edge. The elastic portion includes a bent section having an end extending and bent from the first lateral edge. The supporting portion is disposed on the elastic portion and connected to the other end of the bent section. The rotating wheel is pivotally connected to the supporting portion. When the rotating wheel is pressed by a driving wheel, the supporting portion is driven to compress the elastic portion to move the rotating wheel toward the base, and the rotating wheel is driven to rotate relative to the supporting portion.

摘要： A meshed shell and a sandblasting method are provided. The meshed shell includes a first end portion, a second end portion opposite to the first end portion, a first annular portion, a second annular portion connected to the first annular portion, a first mesh portion between the first end portion and the first annular portion and a second mesh portion between the second end portion and the second annular portion. The weights of the first end portion and the second end portion are the same. A maximum inner diameter of the mesh of the first and second mesh portions is smaller than a penetration size of the component. Both of the sum of the weights of the first and second end portions and the sum of the weights of the first and second annular portions are greater than the sum of the weights of the first and second mesh portions.

摘要： The disclosure relates to a dual printhead assembly and a 3D printing apparatus. The dual printhead assembly includes a base, a printhead module and a switching module. The printhead module includes a positioning swing arm with a bearing disposed at the middle portion thereof, a first printhead unit and a second printhead unit fixed nearby two opposite edges of the bearing, respectively, and a fixing piece passing through the bearing to assemble the printhead module on the base. While a rotation shaft of the switching module is rotated to drive a first cam or a second cam to press an end or another end of an elastic sheet, a third or fourth connecting element disposed on the elastic sheet is driven to press an end or another end of the positioning swing arm, so as to adjust the height difference between the first printhead unit and the second printhead unit.

摘要： An extrusion device of a three-dimensional printer comprises a housing, a nozzle, a ratchet, an idler and a cooling mechanism. The nozzle is connected with the housing, the ratchet is disposed in the housing, and the idler is disposed adjacent to the ratchet. A thermofusible material is jointly held by the ratchet and the idler, and is guided to be extruded through the nozzle. The cooling mechanism comprises an air pump and an air pipe. The air pipe is partially disposed in the housing and connected with the air pump for guiding the air extracted by the air pump to flow into the housing through the air pipe, thereby reducing an environment temperature inside the housing. Therefore, by disposing the air-guiding cooling mechanism, the advantages of enhancing the cooling effect and the printing quality are achieved.
