The specific working process of the invention is as follows: the initial condition of this device is the contraction state, two handles 2 are gathered together to the centre this moment, pin joint about this diamond structure is close to each other, upper and lower pin joint is kept away from each other, first piston 5 is stretched downwards this moment, make the liquid in the piston cylinder 4 can not extrude in the T venturi tube 8, and when first piston 5 contacted wedge 13, wedge 13 launches into in the recess and fixes first piston 5, 16 extension springs between two adjacent T venturi tubes 8 are not stretched this moment, make T venturi tube 8 be axis fore-and-aft direction under the effect of wind spring 15 and arrange, second piston 9 is gathered together to the centre this moment, but this device contraction becomes minimum state under this state, conveniently take and preserve.

When measurement is needed, the two handles 2 are pulled reversely to open the telescopic structure, the upper limit two hinged positions in the diamond structure are close to each other, the left hinged position and the right hinged position are far away from each other, the telescopic rod 6 is contracted to compress the first pressure spring 7, the wedge-shaped block 13 limits the first piston 5 to prevent the first piston 5 from extruding liquid upwards, the left hinged position and the right hinged position are limited to move to the outer sides of the two stirrups at the outermost sides of the to-be-measured stirrups, the limiting rod is enabled to press the two stirrups at the outermost sides of the to-be-measured stirrups, the piston cylinders 4 are located between the neutral positions of the stirrups, due to the characteristic of the cross hinge structure, the theoretical middle positions of the two adjacent stirrups at the piston cylinder 4 are arranged at the moment, the interval between the piston cylinders 4 is increased at the moment, the transverse pipe of the T-shaped pipe 8 is enabled to rotate to the horizontal left and right directions, at this moment, the pulling rope 14 is tightened, so that the pulling rope 14 drives the pull rod 17 through the fixing ring, the wedge blocks 13 are pulled out from the groove, under the reset action of the first tension spring 16, the first piston 5 is enabled to extrude liquid in the piston cylinder 4 into a T-shaped pipe, the second piston 9 drives the L-shaped rod 10 to be outward, the end of the transverse rod of the L-shaped rod 10 is enabled to be in contact with the corresponding stirrup and is limited, the reading on each piston cylinder 4 is the interval between every two adjacent stirrups, and the reading of the pointer 12 is the offset.

After the measurement is completed, the device is pulled out forwards, so that each part is separated from the stirrup, and at the moment, the two handles 2 are combined, so that each part can be reset, and the next measurement work is carried out.

Compared with the traditional equipment, the device has the following advantages:

1. the device ensures that two adjacent rhombic structures are uniformly changed according to the property of the cross-shaped telescopic structure, meanwhile, the piston cylinder 4 is positioned at the theoretical center position of two adjacent stirrups, at the moment, liquid in the piston cylinder 4 is extruded into the T-shaped pipe 8, liquid in the T-shaped pipe 8 is fed to realize the extension of the L-shaped rod 10, the longer the extending length of the two L-shaped rods 10 is, the more liquid in the T-shaped pipe 8 needs to be extruded into the piston cylinder 4, the first piston 5 displacement position in the piston cylinder 4 is therefore the spacing between two stirrups at that point, at the same time, since the piston cylinder 4 is in the theoretical middle position of the two stirrups, if this position is not the actual middle position, the stirrup pointer 12 on which side the piston cylinder 4 is close to indicates the opposite direction, and if the pointer 12 is excessively offset, the position offset can be proved to be excessively large.

2. This device passes through mutually supporting of torsional spring and extension spring 16, realizes that this device violently manage end department in the axis fore-and-aft direction of a plurality of T venturi tubes 8 when the contraction state for this device when not using, can dwindle as far as, conveniently takes and preserves, pulls open when using, and a plurality of T venturi tubes 8 can be transformed into the user state, need not too much operation, make whole use more convenient.

3. This device measures the interval between two stirrups through how much of liquid entering T venturi tube 8, judges the offset through how much that two second pistons 9 stretch out, and two measured data are qualified and unqualified can not influence other measured values that correspond for this device can merge the measurement and can read alone, and each reading position is in on the same water flat line, makes things convenient for the reading.

The invention has novel concept, smart structure and strong practicability, and effectively solves the problems of complex operation and large error in the existing stirrup spacing measurement process.
