The driving mechanism includes a driving component and a sliding component, wherein the outer wall of the driving component is meshedly connected with a gear ring, and the gear ring is slidably connected to the inner cavity of the top seat through the sliding component. The driving component includes a motor installed in the middle of the upper surface of the top seat, and also includes a driving shaft installed at the output end of the motor, and a driving gear is installed on the outer wall of the driving shaft. The driving component also includes a rotating shaft that rotates and is vertically connected to the inner wall of the bottom end of the top seat, and a driven gear is installed on the outer wall of the rotating shaft, and the two ends of the outer wall of the driven gear are respectively meshed with the outer wall of the driving gear and the inner wall of the gear ring. The sliding component includes a slide groove opened along the circumferential direction on the inner wall of the top seat, and also includes a plurality of sliders that can be slidably embedded in the inner cavity of the slide groove, and the sliders are connected to the outer wall of the gear ring.

[0003] In the process of implementing the above embodiments, it was found that there are at least the following problems in the related art:

[0004] This ice rescue cutting device controls the motor, which drives the driving gear through the drive shaft. The meshing action between the teeth drives the driven gear, which in turn drives the ring gear. This ultimately drives the cutting saw, creating a hole in the ice. However, the cutting saw can only revolve, not rotate. As a result, the ice cutting effect is poor, resulting in a slow hole-cutting speed.

The first rotating shaft 2 is rotatably mounted at the center of the support plate 1 and can rotate relative to the support plate 1. The profiled plate 3 is mounted at the bottom end of the first rotating shaft 2 and rotates driven by the first rotating shaft 2. The second rotating shafts 4 are rotatably mounted on the opposite side walls of the profiled plate 3, respectively. The axes of the second rotating shafts 4 on both sides coincide with each other and are both perpendicular to the axis of the first rotating shaft 2. The second rotating shafts 4 on both sides can rotate relative to the opposite side walls of the profiled plate 3. The cutting blades 5 are mounted on the second rotating shafts 4 on both sides and rotate driven by the second rotating shafts 4 on both sides. The third rotating shaft 6 is rotatably mounted on the top surface of the profile plate 3 and is located above the second rotating shafts 4 on either side. The third rotating shafts 6 on either side are rotatable relative to the top surface of the profile plate 3. A first bevel gear 7 is mounted on the bottom surface of the support plate 1 and is sleeved around the first rotating shaft 2, coaxially with the first rotating shaft 2. A second bevel gear 8 is mounted on opposite ends of the third rotating shaft 6 on either side and meshes with the first bevel gear 7.

The belts 11 on both sides drive the second rotating shafts 4 on both sides to rotate, ultimately driving the cutting blades 5 on both sides to rotate around the second rotating shafts 4. Therefore, the cutting blades 5 on both sides can rotate while revolving, improving the ice cutting effect and thereby increasing the hole-drilling speed.

[0039] In the embodiment disclosed herein, the driving motor 14 is controlled to work, and through the coupling, the first rotating shaft 2 can be driven to rotate, and finally the cutting blades 5 on both sides can be caused to revolve and rotate at the same time. Using the driving motor 14 as a power source has the advantages of being easy to use and control.

[0045] In the disclosed embodiment, two second bearing blocks 17 are mounted on opposite sides of the profile plate 3 and are used to support and mount two second bearings. These bearings are used to support and mount two rotatable second shafts 4, reducing friction on the shafts 4 and improving their rotational accuracy.

[0046] Optionally, combined Figure 1 and Figure 3 As shown, the second sealing cover 18 is further included. The second sealing cover 18 is respectively mounted on the end faces of the second bearing seats 17 on both sides, and respectively abuts against the second bearings on both sides.

[0051] In the disclosed embodiment, once the annular plate 20 is placed on the ice surface, the entire device can be supported, eliminating the need for the user to hold the support plate 1 to cut a hole in the ice. The electric telescopic rod 21 can then be controlled to change the height of the support plate 1, ultimately changing the height of the cutting blades 5 on both sides to cut into the ice.
