Preferably, the tooth tip of the internal thread of the binding clip is smaller than the tooth mouth of the screw thread of the foundation bolt.
Preferably, the surface of the tooth point of the internal thread is provided with a rough top surface.
Preferably, the clamp handle ends of the shear rod A and the shear rod B are provided with a drawknot mechanism, and the shear rod B is provided with a mounting hole; the drawknot mechanism comprises a tension spring, a protruding needle, a limiting block and a small pressure spring; one end of the tension spring is fixedly connected with the shear rod A, and the other end of the tension spring is fixedly connected with the protruding needle; the protruding needle is provided with teeth and penetrates through the shear rod B; the limiting block is arranged in the shear rod B, limiting teeth are arranged on the lower sides of the limiting teeth, and the limiting teeth are meshed with the teeth; the small pressure spring is installed on the upper side of the limiting block, and the side face of the limiting block is also provided with a pulling head protruding out of the shearing rod B.
This instrument convenient operation can be fast with the whole clean up of mortar on bolt screw thread surface.
The ash cleaning method of the tool for cleaning the surface mortar of the bolt threads comprises the following steps: clamping the bolt by using a clamp head of a tool; rotating the tool to enable the pincerlike workpiece to move up and down from the bolt thread; removing mortar through shearing force between the threads on the inner side of the binding clip and the threads of the screw thread; and after all the mortar is cleaned, coating machine oil on the screw threads and installing screw thread protectors.
The method for cleaning the bolt mortar provided by the invention is simple and easy to implement, is convenient to operate, can greatly improve the labor productivity, and can save the cost.

Detailed Description
The invention relates to a method for cleaning bolt mortar, which is applied to the field of building construction, and the invention is explained in detail by referring to the attached drawings 1-3 and the embodiment:
a tool for cleaning mortar on the surface of a bolt thread is a pincer-shaped workpiece formed by intersecting a shear rod A and a shear rod B, a rivet is arranged on an intersection point, the shear rod A and the shear rod B at the front part of the rivet are tong heads 1, the shear rod A and the shear rod B at the rear part of the rivet are tong handles 2, and inner threads 3 are arranged on the inner side of the tong heads 1.
The internal thread tooth point 11 of the tool bit provided by the invention is smaller than the tooth mouth 41 of the screw thread of the foundation bolt 4, and the tooth point 11 of the internal thread 3 pricks on mortar when the two threads are meshed.
Further, as shown in fig. 4, the surface of the internally threaded tooth point 1 is provided with a rough top surface.
Further improvements to the above tool: as shown in fig. 5 and 6, the ends of the handles of the shear bar a and the shear bar B are provided with a drawknot mechanism, and the shear bar B is provided with a mounting hole 21; the drawknot mechanism comprises a tension spring 61, a protruding needle 62, a limiting block 65 and a small compression spring 64; one end of a tension spring 61 is fixedly connected with the shear rod A, and the other end is fixedly connected with the protruding needle 62; the protruding needle 62 is provided with teeth 63, and the protruding needle 62 penetrates through the shear rod B; the limiting block 65 is installed in the shear rod B, a limiting tooth 67 is arranged on the lower side of the limiting tooth 67, and the limiting tooth 76 is meshed with the tooth 63; the upper side of the limiting block 65 is provided with a small pressure spring 64, and the side surface of the limiting block 65 is also provided with a pulling head 66 protruding out of the shearing rod B.
