Can conveniently operate handle, accomplish manual rotatory drilling rod and drill, use the stopper to restrict to the degree of depth in hole simultaneously, can realize the accurate processing of required hole depth, simultaneously through the many drilling rods of configuration different diameters, the counter bore of workable different apertures, the requirement of different hole depths, and only need dispose a combination formula handle and can accomplish the operation, both laborsaving, save time conveniently carry, accomodate again.
Description
Technical Field
The utility model relates to an instrument, especially a manual counter bore instrument belongs to instrument manufacturing and designing technical field.
Background
The die cutter blade plate requires additional wood panels of complementary dimensions to be attached to its sides or faces during use, and these wood panels are typically attached to the blade plate using screws. Since the die cutter must be flat during operation, the screw heads require counterbores that do not extend above the plane of the plank. At present, electric drill counterbores are mainly used, but the depth of the counterbores is difficult to control by an electric drill, and the counterbores often fail in operation. Not only causes the loss of the plate, but also has larger danger in the operation process. In addition, the area of the cutter plate of the die cutting machine is large, the die cutting machine is difficult to disassemble, assemble and move, and the electric drill is inconvenient to pull wires. There is therefore a need for improvements in the prior art.
Disclosure of Invention
When the size supplyes the board additional for solving current cross cutting machine cutting board, the counter bore degree of depth that adopts the electric drill counter bore to bring is difficult to control to and the dangerous big problem of operation, the utility model provides a manual counter bore instrument of counter bore degree of depth easy control.
The utility model discloses a following technical scheme accomplishes: the utility model provides a manual counter bore instrument, includes the drilling rod, is equipped with the stopper on its characterized in that drilling rod to the drilling rod upper end is equipped with the handle, so that through the manual rotatory drilling rod drilling of operating handle, uses the stopper to restrict the degree of depth to the hole simultaneously.
The drill rod is a screw rod with a drill bit at the lower end and a square head at the upper end, and the square head at the upper end is matched and connected with the square through hole in the handle.
The drill rods are arranged into a plurality of drill rods with different diameters, and the upper end of each drill rod is a square head with the same size so as to be conveniently connected with the square through hole on the handle in a matching mode, and the processing requirements of counter bores with different apertures are met.
The limiting block is a polygonal body or a cylinder with a vertical through hole in the center, the inner diameter of the vertical through hole is larger than the diameter of the drill rod, a horizontal through hole communicated with the vertical through hole is formed in the side wall of the limiting block, a locking screw is arranged in the horizontal through hole, so that the lower end of the drill rod penetrates through the vertical through hole in the limiting block to extend downwards, the limiting block is fixed on the drill rod through the locking screw after the position of the limiting block on the drill rod is adjusted, and the handle can be operated to enable the drill rod to drill on a workpiece until the limiting block is attached to the workpiece, namely the required hole depth is obtained.
The handle includes that horizontal screw, the middle part are established at both ends and the adapter sleeve pole of square vertical through-hole is established, and the horizontal screw at both ends is respectively with horizon bar looks spiro union, and square vertical through-hole cup joints mutually with the square head of locating the drilling rod upper end to hold the horizon bar and make the drilling rod rotatory, can carry out the drilling operation, the horizon bar through the spiro union both laborsaving operation under leverage, conveniently unpack apart again, carry, accomodate.
The utility model has the advantages of it is following and effect: by adopting the scheme, the handle can be conveniently operated, the manual rotation of the drill rod is completed to drill, the limiting blocks are used for limiting the depth of the holes, the accurate processing of the required hole depth can be realized, simultaneously, through configuring a plurality of drill rods with different diameters, counter bores with different hole diameters and different hole depth requirements can be processed, and the operation can be completed only by configuring one combined handle, so that the combined type drill rod drilling tool is labor-saving, time-saving and convenient to carry and store. The method is an ideal counter bore tool.

FIG. 1 is a schematic diagram of the present invention.
Detailed Description
The present invention will be further described with reference to the accompanying drawings.
The utility model provides a manual counter bore tool, which comprises a drill rod 1, wherein a limiting block 2 is arranged on the drill rod 1, and a handle 5 is arranged at the upper end of the drill rod 1;
the drill rod 1 is a screw rod with a drill bit at the lower end and a square head at the upper end, and the square head at the upper end is matched and connected with the square vertical through hole 8 on the handle 5;
the drill rods 1 are arranged into a plurality of drill rods with different diameters, and the upper end of each drill rod 1 is a square head with the same size so as to be conveniently matched and connected with the square vertical through hole 8 on the handle 5, so that the processing requirements of counter bores with different apertures are met;
the limiting block 2 is a polygonal body or a cylinder with a vertical through hole 3 in the center, the inner diameter of the vertical through hole 3 is larger than the diameter of the drill rod 1, a horizontal through hole 9 communicated with the vertical through hole 3 is formed in the side wall of the limiting block 2, a locking screw 10 is arranged in the horizontal through hole 9, so that the lower end of the drill rod 1 penetrates through the vertical through hole 3 in the limiting block 2 to extend downwards, the limiting block 2 is fixed on the drill rod 1 by using the locking screw 10 after the position of the limiting block 2 on the drill rod 1 is adjusted, and the handle 5 can be operated to enable the drill rod 1 to drill a workpiece until the limiting block 2 is attached to the workpiece, namely the required hole depth is obtained;
the handle 5 includes that horizontal screw 6 is established at both ends, the middle part is established the adapter sleeve pole 7 of square vertical through-hole 8, and the horizontal screw 6 at both ends is respectively with 4 looks spiro couplings of horizon bar, and square vertical through-hole 8 cup joints mutually with the square head of locating drilling rod 1 upper end to hold horizon bar 4 and make the drilling rod rotatory, can carry out the drilling operation, the horizon bar 4 through the spiro coupling both had been laborsaving under leverage, conveniently unpack apart again, carry, accomodate.
