PXE piston seat anchor clamps fixed block

The utility model relates to a PXE piston seat anchor clamps fixed block, the on -line screen storage device comprises a base, the arc groove structure's on base upper portion central point puts the symmetry and sets up the recess into water flat line, has a space between water flat line structure and the original groove structure. Water flat line groove structure's horizontal length is less than arc groove structure's horizontal length. Form the space when base and piston seat base contact, avoided the step of piston seat R57.115 department, area of contact diminishes, and the contact of impurity such as aluminium sweeps etc. Has also been avoided to the space structure. This fixing block structure will be original arc groove structure's the bottom on base upper portion be revised as water flat line groove structure, have a space between its normal water flat line structure and the original groove structure, avoided the step that piston seat R57.115 located, area of contact diminishes, the contact of impurity such as aluminium sweeps etc. Has also been avoided to the space structure.
