The specific embodiment

Below in conjunction with accompanying drawing and concrete embodiment, the present invention is described in further detail.

Shown in Fig. 1 to Figure 10, a stone tongs for gypsum block, comprises main frame 1, the strap 2 that main frame 1 one side settings are extended downward vertically, rotating shaft 3 paralleling with strap 2 of main frame 1 opposite side pivot joint, is connected with the ambulatory splint 4 to downward-extension in rotating shaft 3;

A guide holder 5 perpendicular to main frame 1 is fixed in main frame 1 centre above, one slide block 6 moving up and down is installed on guide holder 5, the lower end of slide block 6 is provided with spacing with hook groove 61, and the end face of the upper surface of slide block 6 and an inverted U-shaped suspension bracket 7 fixes, and the upper surface of suspension bracket 7 is fixed with suspension hook 71;

Two lateral margins of suspension bracket 7 are respectively by active plate 8 of bearing pin 72 pivot joint, the bottom of two active plates 8 is provided with the connecting bore 81 that is roughly inverted triangle, two connecting rods 9 that are fixed on rotating shaft 3 are connected with the inverted triangle connecting bore 81 of two active plates 8 by bearing pin 91 respectively, and the top of two connecting rods 9 two connecting rods 9 in the time of free state can drive rotating shaft 3 to rotate and ambulatory splint 4 is rotated toward outside;

The respective side of 6 times end hook grooves 61 of slide block is provided with suspension bracket 7 and moves up and down the limit assembly 10 that limits selectively slide block 6 upwards stroke or do not limit slide block 6 upwards stroke.

Preferably described limit assembly 10 comprises voussoir limit base 11, upper voussoir 12 and lower wedge block 13, voussoir limit base 11 lower ends are connected with main frame 1, upper end is connected with guide holder 5, can then fix with bolt and main frame 1 at the bottom of voussoir limit base 11 processing key-way shape through hole 111, first fix an adjustment seat 51 on the top of guide holder 5, the top of voussoir limit base 11 is also processed with key-way shape through hole 112 use bolts and is connected with adjustment seat 51, the convenient like this spacing of adjusting between voussoir limit base 11 and guide holder 5.

Upper voussoir 12 and lower wedge block 13 are articulated and are contained in the centre of voussoir limit base 11, can be at the processing part, middle part of upper voussoir 12 cylinder shape groove 121, at the processing part, top of lower wedge block 13 cylinder 131, the part cylinder 131 on lower wedge block 13 tops is enclosed within on the part cylinder shape groove 121 at upper voussoir 12 middle parts and forms pivot joint;

Orienting lug 14 when the top of voussoir limit base 11 inner sides is fixed with and moves on voussoir 12, the middle part of voussoir limit base 11 inner sides is fixed with locating piece 15, the middle part of upper voussoir 12 is equipped with a flexible piece 122 and is matched with described locating piece 15, lower wedge block 13 is provided with fitting projection 132 with 6 times end hook groove 61 respective side of slide block, on lower wedge block 13 voussoir limit base 11 below, roller 16 is housed, the bottom of lower wedge block 13 is provided with the convenient curved surface 133 sliding on roller 16.

Be equipped with

projection

21,41 in strap 2 side relative to ambulatory splint 4, in described

projection

21,41, slipmat 17 be housed.

Operating principle of the present invention is as follows:

Shown in Fig. 3, the present invention is put into above the building block 20 that will capture during by hanging device, ambulatory splint 4 biased outward, upper voussoir 12 and lower wedge block 13 lean against on locating piece 15 by the flexible piece 122 that is contained in upper voussoir 12 middle parts, upper voussoir 12 and lower wedge block 13 are in meta, now slide block 6 can move by easy on and off, and whole limit assembly 10 does not play position-limiting action to slide block, and fixture is in relaxation state.

Shown in Figure 11, when hanging device extracts suspension bracket 7 by suspension hook 71, suspension bracket 7 is by active plate 8 drivening rods 9, rotating shaft 3, ambulatory splint 4 clickwises, also slide block 6 is up extracted simultaneously, ambulatory splint 4 toward the direction of strap 2 near building block 20 is clamped, whole fixture is in clamped condition, and hanging device just can move to required place building block 20 by the present invention; Now go up voussoir 12 and lower wedge block 13 because shift weight on slide block 6 offsets downward, upper voussoir 12 and lower wedge block 13, along roller 16 landings to the next, are carried out the upward stroke of slide block 6 are carried out to spacing preparation.

Shown in Figure 12, hanging device moves to building block 20 behind required place by the present invention, the present invention need to depart from from building block 20, in the time that hanging device puts down building block 20 by the present invention, slide block 6 declines, the hook groove 61 of slide block 6 lower ends just hooks the fitting projection 132 of lower wedge block 13, in the time that hanging device extracts suspension bracket 7 by suspension hook 71 again, slide block 6 upwards extracts lower wedge block 13 and upper voussoir 12 simultaneously, make voussoir 12 and lower wedge block 13 in upper, now go up voussoir 12 and lower wedge block 13 plays position-limiting action to the upward stroke of slide block 6, the top of two connecting rods 9 with respect to the inverted triangle connecting bore 81 of two active plates 8 just in free state and drive rotating shaft 3 left-hand revolutions to make ambulatory splint 4 rotate and unclamp building block 20 toward outside, hanging device just can be removed the present invention from building block 20, simultaneously in the time that suspension bracket 7 is put down again, slide block 6 moves down, upper voussoir 12 and lower wedge block 13 lean against on locating piece 15 by the flexible piece 122 that is contained in upper voussoir 12 middle parts, upper voussoir 12 and lower wedge block 13 are not got position-limiting action in meta to the upward stroke of slide block 6 and are got back to state shown in Fig. 3, and slide block 6 can move by easy on and off again.

Therefore the present invention can realize after suspension bracket 7 puts down and mention ambulatory splint 4 in clamped condition, and then suspension bracket 7 is mentioned the switching of ambulatory splint 4 between relaxation state again after putting down again, convenient carrying building block 20.

Below be only preferred embodiment of the present invention, the change that those skilled in the art does to be equal to by claim all falls into the protection domain of this case.
