[0032] To illustrate in detail the possible application scenarios, technical principles, specific implementable solutions, achievable purposes and effects of the present application, the following will be described in detail with reference to the specific examples listed and in conjunction with the accompanying drawings. The embodiments described herein are only used to more clearly illustrate the technical solutions of the present application, so they are only examples and cannot be used to limit the protection scope of the present application.

[0033] According to some embodiments of the present application, please refer to Figures 1 to 4 , this embodiment relates to a portable logging fixing device, including a base 1, a bracket 2, a fixed tooth assembly 3 and more than two rotating tooth assemblies 4; the bracket 2 is arranged on the base 1, a first cross bar 21 is arranged on the bracket 2, the fixed tooth assembly 3 is arranged on the first cross bar 21, the fixed tooth assembly 3 includes more than two fixed teeth 31, and the tips of the fixed teeth 31 are arranged upwards; a circular rotating rod 22 is arranged on the bracket 2, both ends of the circular rotating rod 22 are fixed on the bracket 2, the circular rotating rod 22 is arranged above the first cross bar 21, and more than two rotating tooth assemblies 4 are rotatably arranged on the circular rotating rod 22;

[0034] The rotating tooth assembly 4 includes a first rotating side plate 41, a rotating tooth plate 42 and a second rotating side plate 43. The top of the first rotating side plate 41 and the top of the second rotating side plate 43 are respectively rotatably connected to the circular rotating rod 22. Both ends of the rotating tooth plate 42 are respectively connected to the first rotating side plate 41 and the second rotating side plate 43. More than two rotating teeth 44 are arranged on the rotating tooth plate 42, and the rotating teeth 44 are arranged downwards; the heights of the rotating tooth plates 42 between two adjacent rotating tooth assemblies 4 are different.

[0035] In this embodiment, the bottom of the bracket 2 can be fixed on the base 1 by bolts, which is convenient for disassembling the bottom of the bracket 2. The middle part of the bracket 2 is fixed by two support rods 5. The base 1, the bracket 2 and the support rods 5 are made of rectangular steel.

[0036] All the fixed teeth 31 are welded to the first cross bar 21. Both ends of the circular rotating rod 22 are fixed to the first vertical rod 25 and the second vertical rod 26. The circular rotating rod 22 itself cannot rotate, and the rotating tooth assembly 4 can rotate around the circular rotating rod 22.

[0037] In the use state, the bottom of the circular wood presses on the fixed teeth 31. Due to the different heights of the rotating tooth assemblies 4, the rotating tooth plates 42 of some rotating tooth assemblies 4 fix the circular wood downward, and the rotating tooth plates 42 of some rotating tooth assemblies 4 are inclined to prevent one end of the circular wood from tilting. The other end of the circular wood can be suspended, and circular woods with different diameters can be fixed.

[0038] According to some embodiments of the present application, optionally, the portable logging fixing device includes five rotating tooth assemblies 4. The five rotating tooth assemblies 4 include a first rotating tooth assembly 4 and a second rotating tooth assembly 4. The height of the rotating tooth plate 42 of the first rotating tooth assembly 4 in the vertical direction is greater than the height of the rotating tooth plate 42 of the second rotating tooth assembly 4 in the vertical direction, and the length of the rotating tooth plate 42 of the first rotating tooth assembly 4 is greater than the length of the rotating tooth plate 42 of the second rotating tooth assembly 4.

[0039] As Figure 3 shown, the height of the rotating tooth plate 42 of the outermost rotating tooth assembly 4 is the highest, and the length of the rotating tooth plate 42 is the longest. The lengths of the first rotating side plate 41 and the second rotating side plate 43 of the outermost rotating tooth assembly 4 in the vertical direction are the shortest; the heights of the rotating tooth plates 42 of the inner rotating tooth assemblies 4 decrease in sequence, and the lengths decrease in sequence, so that the inner rotating tooth assemblies 4 are arranged inside the outer rotating tooth assemblies 4. The height of the rotating tooth plate 42 of the innermost rotating tooth assembly 4 is the lowest, and the length of the rotating tooth plate 42 is the shortest. The lengths of the first rotating side plate 41 and the second rotating side plate 43 of the innermost rotating tooth assembly 4 in the vertical direction are the longest.

[0040] In this way, the five rotating tooth assemblies 4 can be nested with each other, reducing the usage space.

[0041] According to some embodiments of the present application, optionally, the distance between the first rotating side plate 41 and the second rotating side plate 43 in the first rotating tooth assembly 4 is greater than the distance between the first rotating side plate 41 and the second rotating side plate 43 in the second rotating tooth assembly 4, and the length of the first rotating side plate 41 in the first rotating tooth assembly 4 is less than the length of the first rotating side plate 41 in the second rotating tooth assembly 4.

[0042] In this way, the first rotating side plate 41 and the second rotating side plate 43 of the second rotating gear assembly 4 are conveniently arranged inside the first rotating side plate 41 and the second rotating side plate 43 of the first rotating gear assembly 4. At the same time, the rotating tooth plate 42 of the second rotating gear assembly 4 is located below the rotating tooth plate 42 of the first rotating gear assembly 4, and is pushed out of the first rotating gear assembly 4 by the round wood. When the second rotating gear assembly 4 rotates, the rotating tooth plate 42 of the second rotating gear assembly 4 is closer to the round wood, so that the rotating tooth plate 42 of the second rotating gear assembly 4 can be pushed against the round wood to limit the warping of the round wood, thereby fixing the round wood.

[0043] According to some embodiments of the present application, optionally, the fixed tooth assembly 3 includes six fixed teeth 31, and the six fixed teeth 31 are arranged on the first crossbar 21 along the center of the arc. Figure 1 As shown, the six fixing teeth 31 are inclined toward the center of the round timber, so as to better fix the round timber.

[0044] According to some embodiments of the present application, optionally, the base 1 is a first rectangular frame, the bracket 2 is a second rectangular frame, the bottom of the bracket 2 is detachably arranged on the base 1, and the size of the first rectangular frame is larger than the size of the second rectangular frame. Figure 4 As shown, during transportation, the bracket 2 can be arranged inside the base 1, and two support rods 5 are arranged inside the bracket 2, so as to facilitate the transportation of the portable felling fixture.

[0045] According to some embodiments of the present application, the portable logging fixture further comprises two support rods 5, one end of the support rod 5 is detachably connected to the base 1 via a first latch, and the other end of the support rod 5 is detachably connected to the bracket 2 via a second latch, and a support rod 5 is disposed on both sides of the bracket 2. Figure 1 As shown, two support rods 5 are used to support both sides of the bracket 2 respectively, thereby improving the stability of the bracket 2.

[0046] According to some embodiments of the present application, optionally, the bracket 2 further includes a second crossbar 23, a third crossbar 24, a first vertical bar 25 and a second vertical bar 26, the first crossbar 21, the second crossbar 23 and the third crossbar 24 are respectively connected to the first vertical bar 25 and the second vertical bar 26 at both ends, the second crossbar 23, the first crossbar 21 and the third crossbar 24 are arranged from high to low along the vertical direction, and the second crossbar 23 is arranged above the circular rotating rod 22. In this way, a stable fixed frame is formed by the second crossbar 23, the first crossbar 21, the third crossbar 24, the first vertical bar 25 and the second vertical bar 26, and the round wood is fixed between the round rotating rod 22 and the first crossbar 21.

[0047] According to some embodiments of the present application, optionally, the bracket 2 further includes a third vertical rod 27. The third vertical rod 27 is disposed between the first crossbar 21 and the third crossbar 24. The upper and lower ends of the third vertical rod 27 are respectively connected to the middle of the first crossbar 21 and the middle of the third crossbar 24. Thus, the first crossbar 21 is strengthened by the third vertical rod 27, and the stability of the first crossbar 21 is improved.

[0048] Different from the prior art, in the technical solution of the present application, the fixed tooth assembly 3 is disposed on the first crossbar 21. The fixed tooth assembly 3 includes more than two fixed teeth 31, and the tips of the fixed teeth 31 are arranged upward; both ends of the circular rotating rod 22 are fixed to the bracket 2. The circular rotating rod 22 is disposed above the first crossbar 21, and more than two rotating tooth assemblies 4 are rotatably disposed on the circular rotating rod 22; both ends of the rotating tooth plate 42 are respectively connected to the first rotating side plate 41 and the second rotating side plate 43. More than two rotating teeth 44 are disposed on the rotating tooth plate 42, and the rotating teeth 44 are arranged downward; the heights of the rotating tooth plates 42 between two adjacent rotating tooth assemblies 4 are different.

[0049] Thus, by pressing one end of the round wood against the rotating tooth assembly 4, the rotating tooth assembly 4 is rotated. The bottom of the round wood presses on more than two fixed teeth 31. At the top of the round wood, since the heights of the rotating tooth plates 42 between two adjacent rotating tooth assemblies 4 are different, the inclination angles of the rotating tooth plates 42 of more than two rotating tooth assemblies 4 are different, which presses against the top of the round wood, thereby completing the fixation of the round wood. Without finding the center of gravity of the round wood, the round wood can be fixed, and the round wood is not likely to shift, saving time and effort and improving safety.
