[0032] The present invention provides an adjustable punching device, and the method of using the device comprises the following steps:

[0033] Step 1: When performing the punching operation in the initial state, the punching device body 1 is placed on the plate or other punched object that needs to be punched. After placement, the punching device body 1 is fixed, and the position of the sliding card 14 is slid to adjust the drilling position of the drill bit body 21 to be where the hole needs to be punched. The punching device bracket 2 is tilted to the right with the horizontal axis 12 as the center, and the punching device bracket 2 is guided and slid in the arc guide rail 7 through the limit shaft 13 to keep the punching device bracket 2 in a stable state until the punching device bracket 2 is in a horizontal state. At this time, the limit shaft 13 is at the top of the upright guide rail 8, and the right end of the punching device bracket 2 is engaged with the guide slot 11, and the gear II 18 is in contact with the top of the meshing plate 4. At the same time, the drill bit body 21 is adjusted to be in a vertical state, and the motor 15 is started to drive the gear I 16 to rotate, and at the same time, the gear I 16 drives the meshing gear II 18 and gear III 20 to rotate.

[0034] Step 2: Gear I16 engages with gear III20 and rotates to drive the center column 22 to rotate. The center column 22 drives the adjustable drill bit body 21 to rotate. Gear II18 engages with the engagement groove 5 to drive the punching device bracket 2 to move downward. During the downward movement of the punching device bracket 2, the horizontal axis 12 is engaged with the limit card 9, the right end of the punching device bracket 2 is engaged with the guide card groove 11 and the limit axis 13 is engaged with the upright guide rail 8 to keep the punching device bracket 2 in a horizontal state, and the blade 39 on the outside of the adjusting drill bit body 21 performs cutting and punching work at the contacted punching position.

[0035] Step three: when it is necessary to change the size of the punching hole diameter, turn off the motor 15 and pull the punching device bracket 2 upward to reset the punching device bracket 2, hold the adjustable drill bit body 21 to withdraw each telescopic rod 38 from the limit plug hole 35, and then rotate the center column 22. The center column 22 drives each adjustment mechanism 25 and the connecting rod I 28 and the connecting rod II 29 to rotate, so that the connecting rod I 28 and the connecting rod II 29 pull the fixed shaft II 32 on the expansion mechanism 24 to support each expansion mechanism 24 outward or retract it inward, so as to adjust the diameter of the drill bit body 21. During the adjustment process, the expansion mechanism 24 is synchronously expanded or reduced by the hinged pulling drill tip mechanism 23.

[0036] Step 4: After the diameter of the drill bit body 21 is adjusted, one end of each telescopic rod 38 is inserted into the limiting plug hole 35 at the corresponding position to fix the adjusted drill bit body 21 as a whole.

[0037] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions are deemed to be within the scope of protection of the present invention.
