[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0024] Example: See Figure 1-4 The present invention provides a technical solution: an adjustable hinge positioning hole opener, which is mainly aimed at existing hinge hole openers, which are not easy to adjust, especially when opening holes in equipment with non-constant side distances. Its scope of use is narrow, which is not conducive to popularization and use; and there is no limit on the depth of the hole, which improves the problem of hole opening difficulty. The specific solution is as follows: It includes a bearing seat 1, a drive shaft 3 and a hole opening end 31, and the drive shaft 3 and the hole opening end 31 are both arranged inside the overlap sleeve 41, and the centers of the drive shaft 3 and the overlap sleeve 41 are collinear. A quick clamp 7 is fixedly installed on the upper and lower ends of the bearing seat 1, and the quick clamp 7 can improve the fixing stability of the hole opener.

[0025] See also Figure 1 Among them, the front and rear sides of the supporting seat 1 are provided with a scale 6, which can facilitate the adjustment of the distance between the opening end 31 and the side, so that the hole opener can be adjusted according to different side distances to meet the processing needs.

[0026] Furthermore, a guide plate 2 is fixedly mounted on the side of the support base 1 away from the quick-action clamp 7. The cross-section of the guide plate 2 is an inverted "U" shape, and the guide plate 2 is flush with the lower end surface of the support base 1. During the drilling operation of the hole opener, the waste cuttings generated can be guided by the guide plate 2 and discharged through the opening of the guide plate 2, making it easier to collect and dispose of the waste cuttings.

[0027] See also Figure 1 、 Figure 2 and Figure 3An adjustment assembly 5 and a limit assembly 4 are provided on the side of the support base 1 away from the guide plate 2. The limit assembly 4 is located between the adjustment assembly 5 and the guide plate 2. The adjustment assembly 5 can adjust the distance between the opening end 31 and the side edge to meet processing requirements. The limit assembly 4 can limit the downward position of the hole saw to ensure a certain opening depth.

[0028] Specifically, the adjustment assembly 5 includes a reference plate 51, the longitudinal section of which is L-shaped, and the reference plate 51 is arranged below the support seat 1. Sliding rods 52 are fixedly installed on the front and rear sides of the reference plate 51. The support seat 1 is provided with waist-shaped holes for the sliding rods 52 to slide, and adjacent waist-shaped holes form an angle of less than 90 degrees. When the spacing between adjacent sliding rods 52 is increased, the adjacent sliding rods 52 simultaneously move toward the side of the guide plate 2. At this time, the reference plate 51 is against the side. In this state, the distance between the hole opening position and the side of the workpiece can be smaller; similarly, when the adjacent sliding rods 52 simultaneously move toward the side away from the guide plate 2, the distance between the reference plate 51 and the hole opener increases, which can meet the processing needs of a larger distance between the hole opening and the side.

[0029] Furthermore, adjacent sliding rods 52 are provided with drive screws 53 on opposite sides thereof, and adjacent drive screws 53 are connected by adjusting screw sleeves 54, and the adjusting screw sleeves 54 and the drive screw 53 are threadedly connected. The centers of the drive screw 53 and the adjusting screw sleeves 54 are collinear, and the center lines of the drive screw 53 and the sliding rods 52 are perpendicular to each other. When reducing the spacing between the hole opener and the side edge, when the adjusting screw sleeve 54 is rotated in the forward direction, the threaded connection between the adjusting screw sleeve 54 and the drive screw 53 increases the spacing between adjacent sliding rods 52. Similarly, when the adjusting screw sleeve 54 is rotated in the reverse direction, the threaded connection between the adjusting screw sleeve 54 and the drive screw 53 decreases the spacing between adjacent sliding rods 52. Therefore, by rotating the adjusting screw sleeve 54 in the forward or reverse direction as needed, the position of the hole opener and the side edge of the workpiece can be adjusted.

[0030] See also Figure 3 and Figure 4The limiting assembly 4 includes a movable sleeve 42 and a lap sleeve 41. The drive shaft 3 and the movable sleeve 42 are rotatably connected, and the drive shaft 3 is disposed inside the movable sleeve 42. The lap sleeve 41 is fixedly mounted on the bearing seat 1. The movable sleeve 42 is movably connected inside the lap sleeve 41. A return spring 43 is movably connected to the lower end of the movable sleeve 42. The return spring 43 is disposed inside the lap sleeve 41. A groove for the sliding of the movable sleeve 42 is formed on the upper inner side of the lap sleeve 41. In the initial state, through the elastic action of the reset spring 43, the drive shaft 3 makes the hole end 31 higher than the lower end surface of the bearing seat 1 by a certain height, which can effectively avoid the hole end 31 from being damaged by collision during the fixing process; and when in use, the electric drill and the drive shaft 3 are connected and fixed by means of a key and a keyway; during operation, the user holds the electric drill and applies a downward pushing force to the electric drill, so that the electric drill drives the hole end 31 at the end of the drive shaft 3 to perform a drilling operation. Since the overlapping sleeve 41 limits the downward position of the movable sleeve 42, the drilling depth can be guaranteed, which is worthy of promotion and use.

[0031] Working principle: In the initial state of this adjustable hinge positioning hole opener, through the elastic action of the reset spring 43, the driving shaft 3 makes the hole end 31 higher than the lower end surface of the bearing seat 1 by a certain height; according to the distance between the hole and the side, a line is drawn, and then the distance between the hole end 31 and the reference plate 51 is adjusted as needed: when the adjusting screw sleeve 54 is rotated in the forward direction, the threaded connection between the adjusting screw sleeve 54 and the transmission screw 53 is used, and at this time, the distance between adjacent sliding rods 52 is increased; similarly, when the adjusting screw sleeve 54 is rotated in the reverse direction, the adjusting screw sleeve is used to adjust the distance between the adjacent sliding rods 52. 54 and the threaded connection between the transmission screw 53, at this time, the distance between adjacent sliding rods 52 is reduced, and the adjustment is more accurate with the assistance of the scale 6; after the adjustment is completed, the reference plate 51 is attached to the side of the workpiece to be processed, and the entire hole opener is fixed to the processing equipment by the quick clamp 7. The user holds the electric drill and applies a downward pushing force to the electric drill, so that the electric drill drives the hole opening end 31 at the end of the drive shaft 3 to perform the drilling operation. Since the overlapping sleeve 41 limits the downward position of the movable sleeve 42, the drilling depth can be guaranteed.

[0032] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
