[0024] Embodiments

[0025] As Figures 1 to 4As shown, the pre-embedded bolt cleaning and repair device proposed in this utility model includes a sleeve 1 and an electric drill, and further includes: a screw die 3 welded to one end of the sleeve 1 and adapted to the pre-embedded bolt. The screw die 3 is a tool used for processing internal threads. It mainly processes threads in holes of materials such as metal and plastic by cutting. The screw die 3 has a screw hole 31 in the middle that is spirally connected to the pre-embedded bolt. The sleeve 1 has several cleaning holes 11 arranged in a circular array at the end near the screw die 3. The cleaning holes 11 are for removing cement and tape from the screw hole 31. A connecting cover 2 is movably connected to the other end of the sleeve 1. The end of the connecting cover 2 away from the sleeve 1 is fixedly connected to a hexagonal plug 21 installed on the electric drill. The hexagonal plug 21 is a rod connected to the electric drill. The connecting cover 2 has a pair of insertion holes 22 at one end near the hexagonal insertion rod 21. A reinforcing sleeve 23, with its end corresponding to the insertion hole 22, is fixedly connected inside the connecting cover 2. The reinforcing sleeve 23 prevents the insertion hole 22 from being pried out of shape when the metal rod is inserted into it and rotated forcefully. Both ends of the reinforcing sleeve 23 are fixedly connected to the corresponding insertion hole 22. A cleaning mechanism is fixedly installed inside the sleeve 1.

[0026] Furthermore, such as Figures 3 to 4 As shown, a disassembly mechanism is provided at the connecting end of the sleeve 1 and the connecting cover 2 to fix the connection between the sleeve 1 and the connecting cover 2. The disassembly mechanism includes a pair of positioning grooves 13 opened at the end of the sleeve 1 near the connecting cover 2. Each positioning groove 13 has a telescopic hole 12 inside. The inner wall of the end of the connecting cover 2 near the sleeve 1 is fixedly connected to a positioning block 5 that is inserted into the positioning groove 13. Each positioning block 5 has a sliding groove 51. Each sliding groove 51 is fixedly connected to a return spring 52 inside. The return spring 52 causes the sliding block 53 to rotate and disengage from the sliding groove 51 and engage with the telescopic hole 12 when the sliding block 53 is not manually pressed. Each end of the return spring 52 away from the inner wall of the sliding groove 51 is fixedly connected to a sliding block 53 that inserts into the telescopic hole 12. Each end of the sliding block 53 away from the return spring 52 is equipped with a spherical pressing head 54 that automatically retracts into the sliding groove 51 after abutting against the inner wall of the sleeve 1. The spherical pressing head 54 has the function of automatically retracting the sliding block 53 after it is pressed against the inner wall of the sleeve 1. The cleaning mechanism includes an inner cylinder 4 fixedly connected inside the sleeve 1. Inside the inner cylinder 4 is a cleaning wire brush 41 for scraping the outer wall of the pre-embedded bolts. The cleaning wire brush 41 is typically made of metal wire (steel wire). The sleeve 1 and the connecting cover 2 are easily disassembled to facilitate cleaning of the cleaning wire brush 41 inside the inner cylinder 4.

[0027] In this embodiment, a pre-embedded bolt cleaning and repair device is required, such as... Figure 1As shown, first install the hexagonal plug rod 21 on the connecting cover 2 on the electric drill. When it is necessary to replace the corresponding screw plate 3 according to the corresponding embedded bolt, only need to butt the end of the sleeve 1 on the corresponding screw plate 3 with the end of the connecting cover 2, so that a pair of positioning plug blocks 5 on the end of the connecting cover 2 are inserted into the positioning grooves 13 inside one end of the sleeve 1, at this time the spherical pressing head 54 at the end of the sliding clamp block 53 abuts against the inner wall of the sleeve 1, and then the spherical pressing head 54 drives the corresponding sliding clamp block 53 to retract into the sliding groove 51. When the positioning plug blocks 5 are completely clamped into the positioning grooves 13, at this time the sliding clamp block 53 is retracted into the hole 12 and locks the connecting cover 2 through the elastic pushing force of the reset spring 52 in the sliding groove 51, so that the connecting cover 2 cannot be disassembled and moved at the end of the sleeve 1. Then set the screw hole 31 inside the screw plate 3 on the top end of the embedded bolt, start the electric drill to drive the hexagonal plug rod 21 to rotate, and the hexagonal plug rod 21 drives the connecting cover 2, the sleeve 1 and the screw plate 3 to rotate in turn. Since the screw hole 31 in the screw plate 3 is screw-connected with the embedded bolt, the screw plate 3 can be moved on the embedded bolt, and the solidified cement or adhesive tape on the embedded bolt can be cleaned through the screw hole 31 in the moving process. Meanwhile, the curved embedded bolt can be repaired and straightened, which is fast and easy to operate. The rotating sleeve 1 also drives the inner cylinder 4 to rotate, and the cleaned and repaired bolt enters the inner cylinder 4 inside the sleeve 1, at this time the rotated inner cylinder 4 drives the cleaning steel wire brush 41 to clean the remaining materials on the embedded bolt again. When the electric drill is stuck due to the small torque of the screw plate 3 on the embedded bolt, only need to insert a metal rod with a diameter smaller than the insertion hole 22 into the reinforcing sleeve rod 23 through the insertion hole 22, at this time rotating the metal rod can take out the screw plate 3 from the embedded bolt, which is fast and labor-saving.

[0028] The preferred embodiments of the above utility model are only used to help explain the utility model. The preferred embodiments do not describe all the details and limit the utility model to the specific implementation. Obviously, according to the content of the specification, many modifications and changes can be made. The specification selects and specifically describes these embodiments in order to better explain the principle and practical application of the utility model, so that the person skilled in the art can well understand and utilize the utility model. The utility model is limited by the claims and the whole scope and equivalents.
