[0038] According to the above structure, when in use, the staff installs the device at a designated position, uses the connecting plate 101 as the supporting point of the device, installs the base 1 on the boom through the connecting plate 101, and drives the device to move through the boom. When the template of the building is hoisted, the first hydraulic rod 105 is started, and the output end of the first hydraulic rod 105 drives the second reinforcing traction connecting member 104 to rotate along the axis point of the connection between the second reinforcing traction connecting member 104 and the vertical plate 102 through the shaft pin 106. The second reinforcing traction connecting member 104 can drive the cross bar 2 to adjust the angle, and then the reinforcing support top rod 202, the clamping rod 203 and the pull rod 204 are displaced, so that the device is conveniently clamped on both sides of the template when the device is hoisted;

When the polishing and finishing belt 210 rotates, it contacts the template to realize the function of cleaning the impurities remaining on the template.
[0042] When the device is in use, after the first reinforcing traction connecting member 103 and the second reinforcing traction connecting member 104 are unfolded, the screw module 3 drives the lower extending rib 305 to drive the third hydraulic rod 302 and the pressure plate 303 to adjust the position, and then the third hydraulic rod 302 drives the pressure plate 303 to drive the connecting frame 205 to move downward, so that the polishing and dressing belt 210 is pressed on the template to improve the cleaning effect. By bringing the two lower extending ribs 305 close to each other, the function of clamping the template is realized, thereby improving the diversity of the device during lifting.
[0043] Different from the prior art, the present application discloses a hook for hoisting building formwork. By strengthening the displacement of the supporting top rod 202, the clamping rod 203 and the pulling rod 204, the device is conveniently clamped on both sides of the formwork during hoisting. The bottom of the pulling rod 204 can extend to the bottom of the formwork, and the strengthening supporting top rod 202 can be located on the side of the formwork, and the connecting frame 205 can be located on the top of the formwork, so as to realize the function of positioning the formwork and ensure the stability of the formwork during hoisting. The strengthening supporting top rod 202, the clamping rod 203 and the pulling rod 204 can slide on the cross bar 2, so that the device can adapt to formworks of different sizes during use, thereby improving the adaptability of the device during use. The polishing and finishing belt 210 is driven to rotate by the active wheel 206. When the polishing and finishing belt 210 rotates, it contacts the formwork to realize the function of cleaning the impurities remaining on the formwork. By bringing the two lower extending retaining edges 305 close to each other, the function of clamping the formwork is realized, thereby improving the diversity of the device during hoisting, and having good practicality while being convenient to use.
