Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] like Figures 1 to 6 As shown, the utility model provides a reaming structure for an external wall screw hole that is easy to form, including a support rod 1, the upper and lower sides of the support rod 1 are fixedly connected to a hinge seat 2, the inner cavity of the hinge seat 2 is hinged with a reaming plate 3, the side of the reaming plate 3 away from the support rod 1 is fixedly connected to a rotating head 4, the inner cavity of the support rod 1 is fixedly connected to a locking tube 5, the front and rear sides of the locking tube 5 are provided with a locking groove 6, the surface of the locking tube 5 is movably sleeved with a moving ring 7, the front side of the moving ring 7 is fixedly installed with a locking bin 8, the inner cavity of the locking bin 8 is fixedly connected to a locking spring 9, the side of the locking spring 9 close to the locking tube 5 is fixedly connected to a locking rod 10, the side of the locking rod 10 away from the locking tube 5 is fixedly connected to a pull rod 11, the upper and lower sides of the moving ring 7 are fixedly connected to a hinge seat 2 15, and the inner cavity of the hinge seat 2 15 is hinged with a hinge rod 16;

[0024] By pulling the pull rod 11, the movable ring 7 can move on the outer surface of the locking tube 5, and then the locking chamber 8 is pulled to move. When the movable ring 7 moves, it drives the hinge seat 2 15 to move, thereby moving in the direction of the hinge seat 3 17 through the hinge seat 2 15, and then drives the inclination angle of the hinge rod 16 to change, so that the reaming plate 3 moves away from the upper and lower sides of the support rod 1. When the reaming plate 3 moves to the required position, the pull rod 11 is released, and the locking rod 10 is driven by the tension of the locking spring 9 to insert into the inner cavity of the locking groove 6, thereby fixing the position of the movable ring 7, and then fixing the position of the reaming plate 3, thereby realizing that the inclination angle of the hinge rod 16 can be changed by the movable ring 7, and the position of the reaming plate 3 can be adjusted, thereby adjusting the size of the subsequent reaming, so as to meet various needs, and there is no need to replace reaming structures of different models.

[0025] Among them, the left side of the support rod 1 is fixedly connected to the reaming head 12, the inner cavity of the reaming head 12 is movably sleeved with a sleeve tube 13, the left side of the sleeve tube 13 is fixedly connected to a rotating disk 14, the inner cavity of the sleeve tube 13 is engaged with a threaded rod 18, the right side of the threaded rod 18 is fixedly connected to a mounting plate 19, the left side of the mounting plate 19 is fixedly connected to a guide rod 20, and the rear side of the support rod 1 is fixedly connected to a guide ring 21;

[0026] By connecting the mounting plate 19 to the driving device, and then rotating the rotating disk 14 to drive the sleeve 13 to rotate, and then engaging the sleeve 13 with the threaded rod 18, the sleeve 13 is driven to move, and the sleeve 13 drives the support rod 1 to move along the axial direction of the locking bin 8 and the guide rod 20, thereby extending the overall length of the support rod 1 and the locking bin 8, thereby achieving the ability to rotate the rotating disk 14 as needed to drive the length of the support rod 1 to change, thereby changing the reaming depth of the screw hole of the reaming plate 3, further improving practicality.

[0027] The pull rod 11 is located at the center of the inner cavity of the locking spring 9, and the locking rod 10 is inserted into the inner cavity of the locking groove 6;

[0028] Because the pull rod 11 is located at the center of the inner cavity of the locking spring 9 , the pull rod 11 can evenly exert force to pull the locking rod 10 to move, thereby allowing the locking rod 10 to insert into or leave the inner cavity of the locking groove 6 .

[0029] Among them, the side of the expansion plate 3 close to the support rod 1 is fixedly connected to the hinge seat 3 17, and the hinge rod 16 is hinged in the inner cavity of the hinge seat 3 17;

[0030] The hinge rod 16 is hinged to the inner cavity of the hinge seat 3 17, so that the hinge seat 2 15 can drive the tilt angle of the hinge rod 16 to change when it moves, and then the hinge rod 16 supports the reaming plate 3, thereby changing the size of the reaming hole.

[0031] Among them, a rectangular groove is opened on the front side of the support rod 1, and the locking chamber 8 is located in the rectangular groove;

[0032] Through the rectangular groove on the front side of the support rod 1, the locking chamber 8 can be located in the rectangular groove, so that the locking chamber 8 is positioned and supported by the rectangular groove, so that the moving ring 7 will not be offset during the movement, thereby improving the overall stability.

[0033] The pull rod 11 is composed of a ring and a round rod, the round rod is fixedly connected to the locking rod 10, and the ring is located outside the locking chamber 8;

[0034] By pulling the pull ring, the round rod is moved, and the locking rod 10 is then driven to leave the inner cavity of the locking groove 6, thereby improving the convenience for the staff in fixing the position of the reaming plate 3.

[0035] The surface of the sleeve 13 is fixedly connected to the limiting plate, and the sleeve 13 is movably sleeved in the inner cavity of the reaming head 12 through the limiting plate;

[0036] The position of the reaming plate 3 can be fixed by the limiting plate of the sleeve 13, so that when the sleeve 13 rotates and moves along the locking chamber 8, it drives the reaming head 12 to move, and then drives the support rod 1 to move, thereby changing the reaming depth.

[0037] The guide ring 21 movable set is on the surface of the guide rod 20, and the length of the guide rod 20 is the same as that of the support rod 1;

[0038] The guide ring 21 is movably connected to the surface of the guide rod 20. When the driving device drives the mounting plate 19 to rotate, the mounting plate 19 drives the guide rod 20 and the threaded rod 18 to rotate, thereby driving the support rod 1 to rotate for hole expansion, and the support rod 1 is positioned and guided by the guide rod 20 to avoid displacement when the support rod 1 is displaced.

[0039] The working principle and usage process of the present invention are as follows: the mounting plate 19 is connected to the driving device, and then a flat-blade screwdriver is used to rotate the rotating disk 14 to drive the sleeve 13 to rotate. The sleeve 13 is engaged with the threaded rod 18, thereby driving the sleeve 13 to move along the axial direction of the threaded rod 18. The sleeve 13 is movably sleeved in the inner cavity of the reaming head 12, thereby driving the reaming head 12 to move, and then driving the support rod 1 to move along the axial direction of the guide rod 20, thereby adjusting the depth of the hole to be reamed.

[0040] Then pull the reaming head 12 and pull the locking bin 8 to move along the locking tube 5. When the locking bin 8 drives the moving ring 7 to move, the hinge of the hinge seat 2 15 drives the inclination angle of the hinge rod 16 to change, and then the reaming plate 3 is pushed toward the upper and lower sides of the support rod 1 through the hinge seat 3 17, so that the two reaming plates 3 are opened. When the reaming plate 3 moves to the size of the hole that meets the standard, the pull rod 11 is released, and the tension of the locking spring 9 drives the locking rod 10 to insert into the inner cavity of the locking groove 6, thereby fixing the position of the moving ring 7, thereby fixing the position of the reaming plate 3;

[0041] When reaming, the driving device is started to drive the reaming head 12 to rotate and drill into the hole for reaming, and then the reaming plate 3 drives the rotating head 4 to rotate at high speed and enter the inner cavity of the screw to reame it.
