摘要： A dismantling device including a main body, a driving member and an insert is provided. The main body includes a through hole. The driving member is rotatably assembled to the main body. The insert is rotatably disposed in the assembling hole of the first portion. Whereby, an object to be dismantled can be placed in the hole to abut against the insert. A tool is used to drive the driving member to rotate. A protrusion of the driving member is inserted into the through hole for holding the object so that the object can be rotated to be dismantled. As a result, the object can be hold stably by the insert so that the dismantling device can be used for dismantling objects in different sizes.

摘要： A wrench includes a transmitting device and a shell. The transmitting device comprises a rotor, a first working member, a second working member, a first linking member and a second linking member. The first linking member is disposed between the first working member and the rotor. The shell has a containing room for the linking device to be disposed therein. The shell comprises a middle section. The first end of the middle section extends upwardly to connect with the first section. The second end of the middle section extends downwardly to connect with the second section. Thus, the wrench has two stair portions of different horizontal level. And Users can hold the wrench more stably. Because the wrench uses the rotor and two linking members to drive the first working member and the second working member rotating, a total size of the wrench can be kept as smaller as possible.
摘要翻译： 扳手包括发射装置和壳体。 发送装置包括转子，第一工作构件，第二工作构件，第一连接构件和第二连接构件。 第一连接构件设置在第一工作构件和转子之间。 壳体具有用于连接装置的容纳室。 壳体包括中间部分。 中间部分的第一端向上延伸以与第一部分连接。 中间部分的第二端向下延伸以与第二部分连接。 因此，扳手具有两个水平不同的楼梯部分。 用户可以更稳定地握住扳手。 因为扳手使用转子和两个连接构件来驱动第一工作构件和第二工作构件旋转，所以扳手的总尺寸可以保持尽可能小。

摘要： A hub removal tool is provided, including a base, a first working member and a threaded rod. The base has at least one positioning hole and an assembling hole penetrating therethrough in a first direction. The assembling hole defines a central axis extending in the first direction. The first working member is disposed on the base. The first working member has a first screw hole. An opening direction of the first screw hole is identical to the first direction. As viewed in the first direction, the first screw hole is located in a distribution area of the assembling hole and a first axis of the first screw hole is misaligned with the central axis. The threaded rod is screwed with the first screw hole and is movable in the first direction.
