[0018] In order to make the technical problems to be solved, technical solutions and advantages of the present invention more clear, a detailed description will be given below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figure 1As shown, an embodiment of the utility model provides a nut tightening device for a point-supported glass curtain wall, comprising a wrench opening portion 1, a handle portion 11 and an adjustment and positioning mechanism, wherein the adjustment and positioning mechanism comprises a first biaxial connecting piece 3 and a second biaxial connecting piece 6, wherein one end of the first biaxial connecting piece 3 is hinged to the wrench opening portion 1 via a first rotating shaft 2, and the other end is hinged to the second biaxial connecting piece 6 via a second rotating shaft 5, and the end of the second biaxial connecting piece 6 away from the second rotating shaft 5 is hinged to the handle portion 11 via a third rotating shaft 8.

[0020] A first pin 4 is provided in the first rotating shaft 2, a second pin 7 is provided in the second rotating shaft 5, and a third pin 10 is provided in the third rotating shaft 8. The first rotating shaft 2, the second rotating shaft 5 and the third rotating shaft 8 are respectively limited in rotation by the first pin 4, the second pin 7 and the third pin 10. When the wrench opening 1 and the handle 11 are rotated and adjusted, the angle can be adjusted by the first pin, the second pin and the third pin to limit the rotation of the first rotating shaft 2, the second rotating shaft 5 and the third rotating shaft 8.

[0021] A rotating shaft gasket 9 is also provided at the hinged joint between the second biaxial connecting piece 6 and the handle portion 11 . The rotating shaft gasket 9 is provided between the second biaxial connecting piece 6 and the handle portion 11 to prevent looseness between the handle portion and the second biaxial connecting piece.

[0022] The wrench opening 1 is provided with a fixing mechanism connected to the handle 11. The fixing limiting mechanism includes a wrench pin assembly 12 and a fixing screw 14 provided on the wrench opening 1, the wrench pin assembly 12 is provided with a pin connecting plate 13, a fourth rotating shaft 17 is installed on the pin connecting plate 13, the fourth rotating shaft 17 is rotatably connected with a screw connecting plate 16, and the screw connecting plate 16 is fixedly connected to the fixing screw 14 through a screw end plate 15.

[0023] The handle portion 11 is provided with a circular hole corresponding to the fixing screw 14 . One end of the fixing screw 14 is rotatably connected to the wrench opening portion 1 via a fourth rotating shaft 17 , and the other end passes through the circular hole and is connected to the handle portion 11 via a fixing nut 18 .

[0024] The opening of the wrench opening portion 1 corresponds to the nut 21 for point-supporting the glass curtain wall.

[0025] like Figure 2 , Figure 3As shown, adjust the first rotating shaft 2, the second rotating shaft 5 and the third rotating shaft 8 and restrict the rotation of the device through the first pin 4, the second pin 7 and the third pin 10. At the same time, rotate the fixing screw 14 to make the fixing screw 14 and the curtain wall approximately parallel. At this time, the wrench opening 1 has passed through the gap of the curtain wall and entered the inside of the curtain wall. The device is located at the top or bottom of the curtain wall and is in an approximately horizontal state, that is, the state when the device is placed inside the curtain wall. Then, since the point-supported curtain wall glass 19 is fixed to the docking claw 22 through the docking joint 20, by pulling the fixing screw 14, the opening of the wrench opening 1 is stuck to the nut 21 at the docking joint on the curtain wall. At the same time, the first biaxial connecting piece 3 and the second biaxial connecting piece are still in the gap between the point-supported curtain wall glass 19, and the handle 11 is rotated around the third rotating shaft 8 to a position where the handle is more convenient to hold. As shown Figure 4 As shown, before turning the handle, the fixing screw 14 is rotated around the fourth rotating shaft 17 so that the fixing screw 14 and the gap of the point-supported curtain wall glass are in a parallel state, and the fixing screw 14 is passed through the round hole opened on the handle portion 11, and the fixing nut 18 is screwed on to fix the fixing screw 14 and the handle portion 11. At this time, the wrench opening portion 1 on the inner side of the point-supported curtain wall glass 19 is connected with the wrench portion 11 on the outer side of the point-supported curtain wall glass 19 through the fixing screw 14, and the handle portion 11 is rotated along the gap of the point-supported curtain wall glass 19 to make the wrench opening portion 1 rotate synchronously, thereby loosening or tightening the nut 21 at the docking joint inside the point-supported curtain wall glass 19.

[0026] The utility model divides a traditional spanner into three parts: a spanner opening part, a handle part and an adjusting and positioning mechanism. The adjusting and positioning mechanism is rotated and adjusted by a first double-axis connecting piece and a second double-axis connecting piece through a rotating shaft and a pin shaft, so that the spanner opening part and the handle part can rotate with each other, thereby realizing passing through a narrow gap between a point-supported glass curtain wall and surrounding structures or decorative surfaces, and then passing through the spanner opening part from the outside of the glass curtain wall to the inside, and then correspondingly clamped on the glass curtain wall docking claw nut on the indoor side, and fixing the screw rod and the handle part with the nut connected, so that the spanner opening part on the indoor side and the handle part on the outdoor side are connected together, and the handle part is rotated along the gap to realize the loosening or tightening of the docking claw nut.

[0027] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
