[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] Reference Figure 1-4 A hole opener includes an adjusting seat group 1, which includes a base 11. Two guide rails 12 are symmetrically connected to the top of the base 11, and a plate seat 13 is movably installed on the surface of the guide rail 12. An adjusting component 2 is docked with the left side of the top of the plate seat 13. The adjusting component 2 includes a column 21. A sleeve plate 22 is sleeved on the outer side of the column 21, and a hole opening device 3 is installed on the left side of the sleeve plate 22. A fixing component 4 is installed on the left side of the top of the base 11. The fixing component 4 includes a docking plate 41 fixedly connected to the side of the base 11. A square column 42 is connected to the top of the docking plate 41. A slider 43 is movably installed on the square column 42 through a slide groove. The slider 43 is threadedly sleeved on the surface of a threaded shaft 44, and the top of the threaded shaft 44 passes through the interior of the square column 42. A pressing plate 45 is connected to the right side of the slider 43.

[0024] An inserting plate 46 is inserted into the right side of the pressing plate 45 through a slot, and an auxiliary plate 47 is connected to the right side of the inserting plate 46 .

[0025] The bottom ends of the pressing plate 45 and the auxiliary plate 47 are both provided with rubber strip ends. The inner wall of the slot of the pressing plate 45 is connected to a limiting block 48, and the limiting block 48 is inserted into the side of the inserting plate 46 through a limiting groove.

[0026] A connecting plate 14 is connected to the right side of the plate seat 13 , and a cylinder 15 is connected to the back side of the connecting plate 14 . The cylinder 15 is fixedly mounted on the surface of the base 11 .

[0027] The bottom end of the column 21 is connected and fixed to the plate seat 13, and a gear 23 is rotatably installed on the left side of the inner wall of the sleeve plate 22. The shaft end of the gear 23 passes through the sleeve plate 22 and is connected to a rotating rod 24. The gear 23 is meshed and docked with the left side of the column 21 through teeth.

[0028] A fastening bolt 25 is inserted through a threaded hole on the right side of the sleeve plate 22 , and a rubber plate 26 is connected to the end of the fastening bolt 25 .

[0029] Hollow grooves are formed on the surfaces of the pressing plate 45 and the auxiliary plate 47 , and the rubber strip ends of the pressing plate 45 and the auxiliary plate 47 fit in with the sides of the hollow grooves.

[0030] The slot design of the pressing plate 45 can facilitate the pulling and drawing of the inserting plate 46 in the slot of the pressing plate 45, and then facilitate the adjustment of the position of the auxiliary plate 47, and expand the pressing surface area of ​​the hardware plate. When the pressing plate 45 and the auxiliary plate 47 press down the hardware plate, the rubber strip ends at the bottom of the pressing plate 45 and the auxiliary plate 47 can protect the pressed hardware plate to prevent the surface of the hardware plate from being worn during the pressing. The inserting plate 46 can be limited by the limit block 48 to prevent the inserting plate 46 from escaping from the slot of the pressing plate 45 during movement. The displacement of the connecting plate 14 can be controlled by the extension and retraction of the output end of the cylinder 15, so that the connecting plate 14 drives the plate seat 13 to move during the movement, and then the drilling position of the hole opening device 3 can be controlled. 2 can guide the plate seat 13 to ensure the stability of the movement of the plate seat 13. By twisting the rotating rod 24, the gear 23 can be driven to rotate, so that the gear 23 matches the tooth end of the column 21, and then the position of the sleeve plate 22 on the surface of the column 21 is adjusted and changed, which is convenient for changing the height of the hole-opening device 3, and the free controllability of the drilling depth can be ensured. By moving the fastening bolts 25 in the threaded holes of the sleeve plate 22, the fastening bolts 25 can be conveniently moved to push the rubber plate 26 and then contact the outside of the column 21, so as to adjust the tightness and smoothness of the sleeve plate 22 on the surface of the column 21. Through the hollow groove design of the pressing plate 45 and the auxiliary plate 47, it is convenient to observe the state of the hardware plate in the clamping state, and avoid the deformation of the hardware plate under pressure.

[0031] Working principle: According to the attached Figure 3 With attached Figure 4As shown, during use, the hardware plate can be placed on the surface of the base 11, and the threaded shaft 44 can be rotated to control the slider 43 to move in the guide groove of the square column 42. The movement of the slider 43 can control the movement of the pressing plate 45, and then the pressing plate 45 presses down and fixes the side of the hardware plate. According to the use requirements, the auxiliary plate 47 can be pulled to drive the plug plate 46 to move in the slot of the pressing plate 45, so that the auxiliary plate 47 and the pressing plate 45 cooperate with each other to press down the hardware plate.

[0032] Secondly, according to the attached Figure 3 As shown, when in use, the cylinder 15 can be started, so that the output end of the cylinder 15 drives the connecting plate 14 to move, and the connecting plate 14 can drive the plate seat 13 to slide on the surface of the guide rail 12 during movement. The movement of the plate seat 13 can cooperate with the adjustment component 2 to control the movement of the hole-opening device 3, so as to change the position of the drilling hole conveniently. At the same time, after the hole-opening device 3 is started, it drives the hole-opening drill bit to rotate. Figure 2 As shown, the rotary rod 24 can be rotated to drive the gear 23 to move at the tooth end of the column 21, thereby controlling the hole-opening device 3 to move slowly downward.
