The utility model discloses a semi-external spring push-puller, which comprises a core column, a base plate, a return spring and an adjusting terminal, one end of the core column is fixed on the base plate, the other end of the core column is fixed with the adjusting terminal after penetrating out of a shell, and the return spring is sleeved outside the core column. One end of the core column is in threaded connection with the base plate located in the shell, the other end of the core column is screwed through the adjusting terminal located outside the shell in a threaded mode, the return spring is arranged outside the core column in a sleeved mode, and therefore the length of the core column screwed into the adjusting terminal can be controlled according to the size of the shell and the size of the lock rod. And the return spring with the stretching elastic tendency can be matched with the base plate and the adjusting terminal to clamp the lock rod and the shell and replace a torsional spring to achieve return of the lock rod, the external adjusting terminal facilitates holding and drawing of an overhauling worker and indirectly controls the lock rod, and the overhauling safety can be effectively improved.

The utility model discloses a safety protection damping device for automobile maintenance, which relates to the technical field of automobile maintenance equipment, and comprises a bottom plate, universal wheels are arranged at the bottom of the bottom plate, a protection rod is arranged on the bottom plate, a damping mechanism for slowing down vibration is arranged at the top of the bottom plate, and a fixing frame is arranged at the top of the damping mechanism. A first transparent plate is arranged at the top of the fixing frame, an auxiliary mechanism used for lighting automobile maintenance parts is arranged on the first transparent plate, a cleaning mechanism used for cleaning dust on the surfaces of the first transparent plate and the auxiliary mechanism is arranged on the fixing frame, and a storage battery used for providing power for the whole device is arranged at the bottom of the bottom plate. And a controller is arranged on one side of the cleaning mechanism, so that safety protection for maintenance personnel is realized, the maintenance safety is enhanced, dust on the surfaces of the transparent plate I and the transparent plate II is cleaned, light supplement and illumination are performed on a maintenance part, the observation definition of the maintenance part is enhanced, and the maintenance efficiency is improved.

The utility model discloses a rear empennage maintenance platform, which particularly relates to the technical field of helicopter maintenance and comprises a platform, a plurality of first flat gaskets fixedly connected to the top of the platform, handrails fixedly connected to the tops of the first flat gaskets, a stair frame fixedly connected to the front side of the platform, and a support frame fixedly connected to the bottom of the platform. A plurality of second flat gaskets are installed on the inner side of the supporting frame, a plurality of anti-skid screws are installed in the second flat gaskets, and ground supports are fixedly connected to the front sides of the second flat gaskets. By arranging the ground supports, the third flat pads, the elastic pads and the universal wheels, compared with the prior art, the weight of the supporting frame can be evenly dispersed through the ground supports, the possibility of shaking and inclining is reduced, and then the platform can be conveniently driven by the supporting frame to easily move on various grounds through the third flat pads, the elastic pads and the universal wheels; maintenance personnel can quickly move the platform to the empennage position needing to be overhauled, and the working efficiency is improved.
