There are two pieces and be welded on one end of casing, the activity sled block has one piece and is welded on one end of piston rod, the activity sled block
Between two pieces of fixed sled blocks.
Wherein, described sleeve pipe is equipped with external screw thread on the outside of one end of fixed sled block, and annulus is bolted on the external screw thread
Body, the side of the torus are equipped with the support column being radially arranged so that the position of support column can change, convenient to branch
The adjusting of support point.
Wherein, the side of described sleeve pipe offers the first screw hole, and the side of the piston rod is corresponding with the first screw hole
Position is equipped with the second screw hole, is connected by fastening bolt between first screw hole and the second screw hole, need not use piston rod
It will be relatively fixed between piston rod and casing when doing piston motion in plunger shaft.
Wherein, the difference in height between first screw hole and fixed sled block bottom end is equal to the second screw hole and activity sled block bottom end
Between difference in height.
Wherein, the cross section of the plunger shaft and the cross section of piston rod are rectangle.
Wherein, the level interval between two pieces of fixed sled blocks is equal to or more than the width of activity sled block.
Wherein, the fixed sled block is equal with the activity sled height of block.
Wherein, the one end of described sleeve pipe far from fixed sled block is socketed with the first Anti-slip cover, convenient hand-held, reduces user's
The holding area of hand and casing relatively moves.
Wherein, the one end of the piston rod far from activity sled block is socketed with the second Anti-slip cover, convenient hand-held, reduces user
Hand and the holding area of piston rod relatively move.
The utility model has the beneficial effects that：Piston motion is done in sleeve by piston rod so that welding and piston rod
The activity of one end prizes the gap between block multiple impact template and concrete and expands gap, to make fixed sled block enter expansion
Then gap between rear template and concrete is agitated casing and is removed template from concrete surface using lever principle；Make
Hard hit between crowbar and concrete and template can be avoided with the crowbar, reduces the damage to concrete and template.
