Battery pack

A lighting device has a device body including an output terminal for outputting electric energy and a split-type light including at least a lighting element. The device body includes a coupling portion for detachably connecting the split-type light with the device body. The split-type light includes a built-in power supply for supplying electric energy to the lighting element and an input terminal for inputting electric energy to the split-type light. When the split-type light is connected with the device body, the output terminal is electrically connected with the input terminal.

Lighting device

A nailer device has a housing containing a motor and a transmission mechanism. The housing has a nozzle portion with a striking rod for striking a nail arranged therein, the striking rod being moved in a reciprocating manner. A rotating shall is mounted in the housing and the rotating shaft is coupled to the output shaft of the motor through the transmission mechanism. An impact member surrounds the rotating shaft and is moved with the rotating shaft. Corresponding slots are formed on the rotating shaft and the impact member respectively and mate with each other with engagement members being contained in the corresponding slots.

Nailer device

An electrical device, such as a nailer device, has a motor and a gear housing containing a transmission mechanism. The transmission mechanism is coupled to the motor for driving an impact member. The transmission mechanism includes a shaft having a through-hole wherein a first opening of the through-hole is communicated with the interior of the gear housing and a second opening of the through-hole is communicated with an exterior of the gear housing.

A nailer device is carried within a housing having a nozzle portion wherein the nozzle portion is connected with the housing via a head portion of the housing. The nozzle portion includes a sleeve, a fixing member, and a magnetic member located between the sleeve and the fixing member. The fixing member is mounted on the sleeve and the fixing member has a groove in which the magnetic member is arranged.

A nailer device has a housing containing a motor and a striking device arranged in a compact manner. A transmission mechanism is mounted in the housing for translating the rotating motions of the motor into the periodic impact motions upon the striking device. The transmission mechanism includes an impact assembly which imparts the periodic impact motions upon the striking device.

A nailer device includes a housing having a nozzle portion formed in an upper end thereof. A motor and a rotary-linear motion transmission mechanism are arranged in the housing and the rotary-linear transmission mechanism functions to couple an output shaft of the motor to a striking rod disposed in the nozzle portion to thereby move the striking rod in a reciprocating manner. A bias device exerts a force on the striking rod towards the outside of the housing along a longitudinal direction of the striking rod.

A nailer device has a housing containing a motor, a gear box, a transmission mechanism, and a striking rod. The motor, the gear box, and the transmission mechanism cooperate to cause the striking rod to be moved back and forth. The striking rod has a peripheral outer surface and a longitudinal axis and the striking rod and the gear box are connected through a sliding connection structure which allows the striking rod to be moved along its longitudinal axis and which prevents the striking rod from rotating around its longitudinal axis.
