A device for installing an elastic sealing ring on an electronic device includes a clamp module and a pressing module. The clamp module includes a sliding column defining two grooves, two linkage plates, and two pins secured on the bottom end of the linkage plates. The pressing module includes a bracket and a knockout plate. The linkage plates are rotatably installed on the bracket and the sliding column can slide relative to the bracket. The knockout plate can slide relative to the bracket, to install the sealing ring on an electronic device.

An object retrieval device for retrieving objects is provided. The object retrieval device comprises an elongated hollow housing having a first end and a second end. A grab hook is attached to the second end of the housing with the grab hook having an inner curved surface. A rod is slidably mounted within the housing with the rod having a first end and a second end. A handle is mounted to the first end of the rod. A spring mechanism is mounted between the first end of the housing and the handle with the spring mechanism biasing the rod in a general direction away from the grab hook. Upon manipulating the rod to overcome the bias of the spring mechanism, the second end of the rod contacts the inner curved surface of the grab hook thereby releasably securing objects between the second end of the rod and the grab hook.

A gear grasping device includes a main body, a first jaw, a second jaw, and an adjustment means. The main body is provided with a curved portion accompanied with an opening. The first jaw and the second jaw are disposed on the main body. The opening is arranged between the first jaw and the second jaw. By the adjustment means, position of the first jaw is changeable for adjusting a jaw span between the first jaw and the second jaw. Therefore, the gear grasping device is fit for sizes of gears, and is operation-friendly.
