A vibration damping device for use in a work glove includes a planar plastic body having palm, thumb and finger areas, and a plurality of resilient, compressible projections extending outwardly from at least one surface of the body. Planar areas or webs in the knuckle and finger joint areas of the body make the device flexible for easy grasping of a tool and bunching of projections in such areas. Bunching of the projections is also avoided or reduced by arranging the projections in parallel, arcuate rows extending from the thumb side rearwardly toward the wrist end of the body.

The invention discloses an improved inner-pushing type clamping device for a numerical control tube bending machine and belongs to the field of numerical control tube bending machines. The improved inner-pushing type clamping device solves the problems that an oil cylinder of an existing clamping device for a numerical control tube bending machine is poor in rotation sealing in the autorotation process and is likely to leak oil, and the service life is short. The improved inner-pushing type clamping device comprises a flexible chuck, an oil cylinder and a component, wherein the flexible chuck and the oil cylinder are connected through the component. The component for connecting the flexible chuck and the oil cylinder comprises a chuck pushing bush and a rotating rod. The oil cylinder comprises a cylinder body and a piston rod arranged in the cylinder body, and the chuck pushing bush is arranged at the stretching-out end of the piston rod, is fixed relative to the piston rod in the axial direction and can relatively rotate around the axis. The rotating rod is arranged in the piston rod, and is connected with the chuck pushing bush in the connecting mode that the rotating rod and the chuck pushing bush can rotate synchronous and move relatively in the axial direction. The flexible chuck is arranged at one end of the rotating rod. By means of the improved inner-pushing type clamping device, the problem of oil leakage caused by poor rotation sealing of the oil cylinder can be solved, so that the working stability of the clamping device is improved, and the service life is prolonged.
