An ampoule opener has an opening unit and a cover unit. The opening unit is a rigid frame and has two panels, two head-clamping holes and two pairs of wave-shaped flanges. The panels are respectively an upper panel and a lower panel. The head-clamping holes are elongated in length and tapered in width and are respectively formed through the panels. The pairs of wave-shaped flanges are formed between the panels and the head-clamping holes. The cover unit is flexible, is detachably mounted around the opening unit and has two covering boards, a mounting recess, two body-clamping holes and two pairs of wave-shaped edges. The body-clamping holes are elongated in length and tapered in width and are respectively formed through the mounting boards and communicate with the mounting recess. The pairs of wave-shaped edges are formed between the mounting boards and the body-clamping holes.

A derailleur cable detecting assembly for an electric-auxiliary bicycle has a body and a detecting device. The body is mounted on a frame of the electric-auxiliary bicycle, is connected to a derailleur cable and has a casing and a cover. The casing has a chamber and a through hole. The cover is detachably mounted on the casing to mount a cable wire of the derailleur cable in the body. The detecting device is mounted in the body, is connected to the derailleur cable and has a circuit board and a magnetic element. The circuit board is mounted in the chamber of the casing, faces the cable wire and has an electric wire and multiple magnetic sensors. The magnetic sensors are mounted on the circuit board at intervals. The magnetic element is mounted on the cable wire between the casing and the cover, facing the magnetic sensors of the circuit board.

A grease output device for an electrical grease gun has a body, a double-cam member and a driving member. The body has a holder and a seat mounted with the holder. The double-cam member connects to the body and has a driven unit and a driving unit. The driven unit has a driven gear and two cams misaligning with the driven gear. The driving gear has two rings mounted around the cams and two pistol rods connecting to the rings. The driving unit has a driving gear engaging with the driven gear. The driving member connects to the body to rotate the driving gear so the driven gear is rotated to push the rings. Hence, the grease can flow out of the body successively by the pistol two pistol rods moving back and forth alternatively.

A battery operated grease gun has a motor that drives a planetary gear assembly that is coupled to a pump assembly that drives a plunger reciprocally in an grease passage to discharge grease through a discharge spout. The pressure in the grease exerts a reaction force on the plunger that will change torque of the motor. The change of the torque of the motor will simultaneously effect voltage applied to the motor. When the voltage in the motor changes, an electronic pressure regulator measures the voltage in the motor to determine the pressure in the grease in the grease passage and stops the motor as the pressure in the grease reaches preset given valves in the pressure regulating device.
