摘要： A string cutter includes two handles, two fixing devices, and a cutting string. The cutting string has two ends each secured on the respective handle by the respective fixing device. Each of the two handles includes a loop-shaped handgrip for insertion and holding of a user's fingers. The handgrip has two sides each provided with a protection rib, for encompassing and protecting the user's fingers received in the handgrip. Thus, when the cutting string is broken due to wear or excessive pull and is sprung toward thehandles, the broken cutting string will be blocked and stopped by the protection rib of each of the two handles, thereby efficiently preventing the broken cutting string from injuring the user's fingers, so as to protect the user's safety.

摘要翻译： 弦切割器包括两个手柄，两个固定装置和切割线。 切割线具有两个端部，每个端部通过相应的固定装置固定在相应的手柄上。 两个手柄中的每一个包括用于插入和保持使用者手指的环形手柄。 手柄具有两个侧面，每个侧面设置有保护肋，用于包围和保护接收在手柄中的使用者手指。 因此，当切割线由于磨损或过度拉动而被破坏并且朝向手柄弹起时，断开的切割线将被两个手柄中的每个的保护肋阻挡和停止，从而有效地防止断开的切割线束损伤 用户手指，以保护用户的安全。

摘要： A tube joint that can be used as a volume control valve, air sprayer or/and a T-tube. The multifunction tube joint mainly contains: an elongated body, a revolving valve, a stem, a branch, a piston valve rod, a button and a spring. The elongated body contains: a main channel longitudinally therethrough, a protrusion thereon and a tunnel vertically therethrough. The protrusion has a receptacle therein communicated with the main channel. The revolving valve is rotably received through the tunnel. The revolving valve has a controlling channel vertically therethrough. The controlling channel is communicable to the main channel. The stem is connected to the receptacle. The stem has a stem channel therein, communicable with the main channel. The branch is connected to the stem. The branch has a branch channel therein communicated with the stem channel of the stem. The piston valve rod is slidably received in the stem channel of the stem with a first end extended out thereof. The button is mounted with the first end of the piston valve rod. The button is engagable with the stem. The spring is placed with one end against a bottom of the receptacle of the protrusion and with another end against a second end of the piston valve rod. The piston valve rod can be pressed against the spring to let the main channel to communicate with the branch channel through the stem channel and the piston valve rod can be released to block communication between the main channel and the branch channel.

摘要： A removal apparatus of a threaded post contains: a drive rod, a connection element, an actuation element, and a slidable sleeve. The connection element includes a locking groove and a notch. The actuation element includes a fitting fringe corresponding to the connection element, a cylindrical neck having a diameter less than a diameter of the fitting fringe, and an engagement disc having a diameter more than the diameter of the cylindrical neck. The diameter of fitting fringe is equal to a diameter of the connection element. The slidable sleeve includes a coupling space having a diameter equal to the diameter of the fitting fringe and the diameter of the connection element. The slidable sleeve is slid so that the coupling space abuts against the fitting fringe and the connection element, and the engagement disc is engaged in the locking groove.
