[0060] A connecting shaft 601 located inside the housing 101 passes through the housing 101 and extends out of the housing 101. A drill bit 30 is mounted on the connecting shaft 601 extending out of the housing 101. The connection between the drill bit and the connecting shaft is prior art and will not be described in detail here.

[0061] Furthermore, a second gear 803 is provided on the connecting shaft 601 located inside the housing 101. The second gear 803 meshes with the first gear 802 installed on the adjusting shaft 90 to form a gear transmission.

[0063] It should be noted that during use, simply rotate the manual adjuster 40. The rotation of the manual adjuster 40 drives the adjusting shaft 90 to rotate, which in turn drives the second gear 802 mounted on the adjusting shaft 90 to rotate. The rotation of the second gear 802 drives the first gear 802 to rotate, which in turn drives the connecting shaft 601 to rotate, which in turn drives the drill bit mounted on the connecting shaft to rotate.

[0064] Furthermore, the outer wall of the support column 101 is provided with an outwardly protruding slider 103 integrated therewith. Multiple sets of sliders 103 are arranged and evenly distributed around the circumference of the support column 101.

[0065] The inner wall of the sleeve 105 located outside the support column 101 is provided with a groove for the slider 103 to extend into, so that the groove and the slider can be used together to slide; and it is fixedly connected by fasteners 104.

[0066] In this embodiment, the fastener 104 includes a fastening screw and a fastening nut, and the fastening screw of the fastener 104 passes through the sleeve 105 and the threaded hole provided on the support column 102 in sequence, and is threadedly connected.

[0067] Furthermore, a workbench 50 is welded to the outer wall of the sleeve 105.

[0068] In this embodiment, when it is necessary to adjust the height between the workbench and the drill bit, simply rotate the fastener 104 to loosen it, and then the worker pushes the sleeve 105 up or down. When it is pushed to the appropriate position, rotate the fastening screw of the fastener 104 to screw it in, and then tighten the fastening nut.

[0069] This utility model has a simple overall structure, which allows for height adjustment while reducing overall cost by 35%.

[0070] Example 2

[0071] Existing radial drilling machines suffer from limited functionality. To address the aforementioned technical issues, please refer to [link / reference needed]. Figure 3-6 As shown,

[0072] The drive system 20 is fixedly installed on the housing 101 by fastening screws, and the drive system 20 drives the rotating shaft 601 to rotate through the transmission system 60.

[0073] Specifically, the transmission system 60 includes a first drive pulley disposed on the drive shaft of the drive system 20, and drives a first driven pulley via a first belt. A second drive pulley is coaxially disposed on the shaft of the first driven pulley. The second drive pulley drives the second driven pulley via a second belt. The second driven pulley is disposed on the rotating shaft 601.

[0074] In this embodiment, by activating the drive system 20, the drive system drives the first belt to rotate the first driven pulley, which in turn drives the coaxially arranged second driving pulley. The pulley shaft of the second driving pulley drives the second belt to rotate, which in turn drives the second driven pulley, thereby driving the drill bit arranged on the rotating shaft 601 to rotate.

[0075] Furthermore, a first turbine 801 is provided on the adjustment shaft 90 of the manual adjuster 40 located inside the housing, and the first turbine 801 is engaged with the helix angle of the first worm 606 to form a worm gear drive, and a second turbine 608 is installed on the smooth end of the first worm 606, and the second turbine 608 is engaged with the helix angle of the second worm 609 to form a worm gear drive;

[0076] The smooth end of the second worm gear 609 is provided with a fourth driving pulley, and the fourth driving pulley drives a fourth driven pulley through a fourth belt. The fourth driven pulley is provided on the connecting shaft 602, and a third driving pulley is coaxially provided on the connecting shaft 602. The third driving pulley drives a third driven pulley through a third belt.

[0077] Furthermore, the third driven pulley is mounted on the rotating shaft 601 and is coaxially arranged with the second driven pulley.

[0078] In this embodiment, when manual adjustment is required, it is only necessary to rotate the manual adjuster 40, which in turn drives the adjustment shaft 90 to rotate, which in turn drives the first turbine 801 to rotate, and the first turbine 801 to rotate the first worm gear 606.

[0079] The second turbine 608, mounted on the first worm 606, rotates, which in turn rotates the second worm 609, which in turn rotates the fourth drive pulley mounted on the second worm. This, in turn, drives the fourth driven pulley via the fourth belt, which in turn drives the coupling shaft 602 to rotate. The rotation of the coupling shaft 602 drives the third drive pulley to rotate, which in turn drives the third belt drive, which in turn drives the third driven pulley to rotate, which in turn drives the drill bit mounted on the rotating shaft 601 to rotate.
