Preferably, the circular holes have a diameter of 10 mm.
Preferably, the handle is a stainless steel cylindrical rod with the diameter of 8-10 mm.
Preferably, a plastic grip or a wrapping belt is additionally arranged at the two ends of the handle.
Preferably, the cup body is a cylinder with a height of 120mm and 130 mm.
Preferably, a dial gauge is arranged outside the cup wall of the cup body, and the dial gauge is arranged above the baffle at the bottom of the main rod at a height of 0 mm.
Preferably, the radius of the baffle is 1-2 mm smaller than the inner radius of the cup body.
Compared with the prior art, the invention has the following remarkable advantages: when the direct-connected air compressor is used for stripping, the direct-connected air compressor can be aligned to the gap of the bottom opening of the cup body, the condensed material blocks free circulation of air, the material can be pushed out from the opening at the upper part of the cup body by air pressure, and if the material cannot be completely pushed out or the direct-connected air compressor is not available, the handle can be assembled with the main rod to pull the material out from the inner part of the cup body.
The present invention is described in further detail below with reference to the attached drawings.

Fig. 2 is a schematic diagram of the boom structure.
Fig. 3 is a schematic view of the structure of the sealing cover.
Fig. 4 is a schematic view of the handle structure.
Detailed Description
As shown in fig. 1 and 3, an easily removable formwork grout bleeding rate, expansion ratio tester, including cup 3, be used for carrying out sealed lid 2, mobile jib 1 and the handle 9 sealed to the rim of a cup, mobile jib 1 includes the body of rod 6 and sets up the baffle 7 in the 6 one end of the body of rod, and the body of rod 6 inserts cup 3 through the trompil on sealed lid 2, and cup 3 bottom is arranged in to baffle 7, 3 bottoms of cup are equipped with gas pocket 4, press out the interior examination mould of cup through the available associated mode air compressor of gas pocket 4. The other end of the rod body 6 is provided with a circular hole 5. The handle 9 can be inserted into the circular hole 5 on the rod body.
In a further embodiment, the circular holes 5 have a diameter of 10 mm.
In a further embodiment, the handle 9 is a stainless steel cylindrical rod with a diameter of 8-10 mm.
In a further embodiment, plastic grips or wrapping belts are additionally arranged at two ends of the handle 9 to increase friction force, so that force generation and mold removal are facilitated.
In a further embodiment, the cup body is a cylinder with a height of 120mm and 130 mm;
in a further embodiment, a dial gauge 10 is arranged outside the cup wall of the cup body 3, so that reading is facilitated; the height of the dial gauge at 0mm is arranged above the baffle 7 at the bottom of the main rod 1;
in a further embodiment, as shown in fig. 2, the rod body is a stainless steel rod with a diameter of 10-15 mm; the baffle is a stainless steel circular sheet with the thickness of 1-3 mm;
in a further embodiment, the radius of the baffle 7 is adjusted along with the inner radius of the cup body, and the radius is smaller than the inner radius of the cup body 3 by 1-2 mm.
The working process of the invention is as follows: when the mold is removed, the direct air compressor can be aligned to the gap of the bottom opening of the cup body, and the condensed material blocks the free circulation of air, so that the material can be pushed out from the opening at the upper part of the cup body by air pressure. If the material can not be completely pushed out or the direct-connected air compressor is not available, the handle can be assembled on the main rod, and the material can be pulled out from the interior of the cup body.
