The connecting rod can better apply the acting force tightly applied to the template to the isolation sleeve, so that the template hole can be better sealed. And the isolation sleeve made of the elastic material is convenient to realize the separation from the concrete.
Further setting the following steps: and the connecting rod is in threaded connection with a fixing nut for fixing the template.
Through adopting above-mentioned technical scheme, realize through fixation nut and connecting rod threaded connection's mode that the template is fixed on the connecting rod for the fixed mode of connecting rod and template is more convenient.
Further setting the following steps: the butterfly buckle is used for positioning the framework and is arranged on the connecting rod, and the driving piece is arranged on the connecting rod and used for driving the butterfly buckle to abut against the framework.
Through adopting above-mentioned technical scheme, the butterfly is detained and better fixed that the skeleton lies in on the connecting rod can be realized to the cooperation between the two of driving piece.
Further setting the following steps: the driving piece comprises a pressing nut in threaded connection with the connecting rod.
Through adopting above-mentioned technical scheme, support tight nut and connecting rod threaded connection's mode drive butterfly buckle and skeleton and move towards pre-buried dead lever one side to realize better supporting to fasten fixedly to the skeleton.
Further setting the following steps: when the connecting piece is in threaded connection with the embedded fixed rod and the connecting rod at the same time, the connecting piece, the embedded fixed rod and the connecting rod are coaxially arranged.
Through adopting above-mentioned technical scheme, the mode of coaxial setting is easy to assemble.
Further setting the following steps: the peripheral wall of the connecting piece is in a polygonal shape which can be driven by a tool to rotate the connecting piece.
Through adopting above-mentioned technical scheme, can drive the driving medium through the instrument and rotate to realize the better separation of driving medium and pre-buried dead lever.
To sum up, the utility model discloses following beneficial effect has: the utility model discloses easy and simple to handle, the cost of labor is low, the installation effectiveness is high.
