  • Publication number: 20250058443
    Abstract: A tool includes a nut and a bearing module. The nut is engageable with a screw connected to a spacer to allow a hammer to hit the nut to remove the screw from the spacer. The bearing middle is located between the nut and the spacer to allow smooth rotation of the nut relative to the screw to extend the screw through the spacer, thereby connecting the screw to the spacer.

  • Patent number: 11872673
    Abstract: An oil drain combination for a brake contains: a wrench and a draining assembly. The wrench is a ratchet wrench. The draining assembly is connected in the wrench and includes a coupling shaft, a fitting member, a first joining tube, and a fixing member. The fitting member is rotatably accommodated in a drive head of the wrench. An axial line of the fixing member extends from the first segment of the fixing member to a second segment of the fixing member and insects with a central line of the coupling shaft perpendicularly. The first joining tube has an accommodation orifice and an axial orifice. The coupling shaft has a blind orifice and multiple radial orifices. The fixing member has a first connection hole communicating with a second connection hole.

  • Publication number: 20220026019
    Abstract: A lubricating can has a grease cup, bolt, piston, pressing base, bearing placement portion and a rotation driving component. The fixed end of the bolt is fixed on the grease cup bottom. The piston is housed inside the lubricating trough. The piston has a pressing surface, a bearing surface and a lateral ring surface that is tightly fitted on and can slide along the inner wall. The center of the piston is formed with a through hole and a plurality of lubricating guide holes. The through hole is sheathed on the bolt. The lower end pressing portion of the pressing base has a screw hole to fit the bolt. The bearing placement portion is defined and formed by the space between the lower end pressing portion and the bearing surface of the piston. The rotation driving component is configured on the upper end bearing portion of the pressing base.

  • Publication number: 20210140499
    Abstract: A screw thread bidirectionally driven disc brake piston resetting tool has a main body, a first clamping plate and a second clamping plate, wherein both sides of the main body are adjacent to the first clamping plate and the second clamping plate respectively. A driving piece and a tubular revolving part are pivoted in the main body. The driving piece drives the revolving part to revolve. The revolving part is screwed on a first connecting piece and a second connecting piece respectively. The first connecting piece and the second connecting piece are linked with the first clamping plate and the second clamping plate respectively, shifting oppositely. The distance between the first clamping plate and the second clamping plate can be increased without increasing the thickness of the main body, and it is applicable to piston resetting push-back operation for disc brakes of different sizes.
