Detailed Implementation
[0025] To make the objectives, technical solutions, and beneficial effects of this utility model clearer, the preferred embodiments of this utility model will be described in detail below with reference to the accompanying drawings, so as to facilitate the understanding of those skilled in the art.
[0026] In the description of this utility model, unless otherwise stated, the terms "inner", "outer", "left", "right", etc., indicate the orientation or state relationship based on the orientation or state relationship shown in the drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0027] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "equipped with" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art will understand the specific meaning of the above terms in this invention according to the specific circumstances. Example 1
[0028] like Figure 1-5As shown, the electric drill auxiliary tool includes a locking assembly, an electric drill support assembly, and an angle adjustment assembly. The locking assembly includes an upper notched locking ring 1, a lower notched locking ring 2, and a locking ring connecting rod 3. The openings of the upper notched locking ring 1 and the lower notched locking ring 2 are offset vertically. The locking ring connecting rod 3 connects the upper notched locking ring 1 and the lower notched locking ring 2. The offset notches of the upper notched locking ring 1 and the lower notched locking ring 2 allow the locking assembly to be directly locked to the tree trunk without disassembly.
[0029] As a preferred embodiment, anti-slip strips (or anti-slip pads) are respectively provided on the inner sides of the notched ring 1 and the lower notched ring 2. These anti-slip strips (or anti-slip pads) are positioned between the tree trunk and the notched ring 1 and the lower notched ring 2, increasing the friction between them and the tree trunk and preventing the device from sliding down the trunk during use. The anti-slip strips can be glued to the inner sides of the notched ring 1 and the lower notched ring 2 before the device is secured to the tree, or the anti-slip pads can be placed between the notched ring 1 and the lower notched ring 2 and the tree trunk after the device is secured. Either method of placing the anti-slip strips (or anti-slip pads) between the notched ring 1 and the lower notched ring 2 and the tree trunk is acceptable (given that the anti-slip pad is a conventional structure, it is omitted from the accompanying drawings to avoid affecting the display of other structures)).
[0030] The inner diameter of the notched retaining ring 2 and the retaining ring connecting rod 3 is slightly larger than the outer diameter of the tree trunk. As a preferred embodiment, the ring length (total length after straightening) of the upper notched retaining ring 1 is approximately 1 / 2 to 3 / 4 of the total length of the entire complete ring, and the ring length of the lower notched retaining ring 2 is approximately 1 / 2 or slightly less than 1 / 2 of the total circumference of the complete ring. This ring length design ensures that the formed notch can be securely fastened to the tree trunk and is not prone to slipping. Two retaining ring connecting rods 3 are provided, each vertically connected between the upper notched retaining ring 1 and the lower notched retaining ring 2. A handle 4 is fixed to the retaining ring connecting rod 3. During use, holding the handle 4 prevents the fastening components from slipping down the tree trunk.
[0031] The drill support assembly includes an inner connecting rod 5, an outer connecting rod 15, three sliding rods 7, three sliding sleeves 6, and a drill clamping assembly. The three sliding rods 7 are arranged in parallel and vertically connected between the inner connecting rod 5 and the outer connecting rod 15. The three sliding sleeves 6 are slidably fitted onto the three sliding rods 7. The inner end of the middle sliding rod 7 is provided with a spring stop 9, and an outer spring 8. The inner end of the spring 8 is fixedly connected to the spring stop 9, and the outer end is fixedly connected to the sliding sleeve 6. The drill clamping assembly includes a lower clamping plate 10, an upper clamping plate 11, a hinge assembly 12, and connecting bolts 13. The left side of the lower clamping plate 10 and the upper clamping plate 11 (see attached diagram) Figure 4(The orientation is described) It is hinged by the hinge assembly 12, and the right side is connected by the adjustable spacing of the connecting bolt 13. The upper clamping plate 11 is an arc-shaped plate. In use, the electric drill is limited by passing it through the space between the upper clamping plate 11 and the lower clamping plate 10. The spacing between the upper clamping plate 11 and the lower clamping plate 10 can be adjusted by the connecting bolt 13 so that electric drills of different sizes can be clamped and positioned by the upper clamping plate 11 and the lower clamping plate 10.
[0032] Three sliding sleeves 6 are directly fixed to the bottom surface of the lower clamping plate 10 or fixed to the bottom surface of the lower clamping plate 10 via connecting rods 20. During drilling, the electric drill is positioned by the drill clamping assembly, and during drilling, the drill clamping assembly moves along the three sliding rods 7 under the limitation of the sliding sleeves 6, preventing the drill from shaking and ensuring accurate drilling position. By installing a spring 8 around the middle sliding rod 7, the spring 8 provides a reaction force to the drill during drilling, controlling the drilling speed and making it easier to control the drilling depth. This prevents excessive drilling depth due to difficulty in controlling the drilling speed caused by unfamiliarity with the operation. The sliding rod 7 also has graduations, which allow for control of the drilling depth.
[0033] In this embodiment, the drill support assembly and the locking assembly are connected at an adjustable angle via an angle adjustment assembly. The angle adjustment assembly mainly includes an angle adjustment vertical rod 14 and an angle adjustment horizontal rod 16. The structure for achieving the angle adjustment function is as follows:
[0034] A crossbar 21 is fixed to the retaining ring connecting rod 3. A hinge shaft fixing sleeve 24 is welded to each of the outer ends of the crossbar 21 (with the closer end to the trunk being the inner end and the farther end being the outer end). A hinge shaft 23 is positioned between the two hinge shaft fixing sleeves 24. A hinge collar 22, rotatably connected to the hinge shaft 23, is installed at the upper end of the angle adjusting vertical rod 14. Two parallel angle adjusting crossbars 16 are installed between the inner connecting rod 5 and the outer connecting rod 15, and these crossbars 16 are positioned beside the three sliding rods. The lower end of the angle adjusting vertical rod 14 passes through the gap between the two angle adjusting crossbars 16 and is clamped to the two crossbars 16 in an adjustable position using upper bolts 17 and lower bolts 18. Two collars 19 are welded to the outer side of the lower notch retaining ring 2. The inner connecting rod 5 is cylindrical and rotatably connected to the two collars 19.
[0035] When the angle of the electric drill support assembly needs to be adjusted, simply adjust the clamping position of the angle adjusting vertical rod 14 and the two angle adjusting horizontal rods 16. By adjusting the angle of the electric drill support assembly and the clamping assembly, the angle of the electric drill clamping assembly is adjusted, ultimately achieving the effect of adjusting the drilling angle of the electric drill.
[0036] The hinge assembly 12 described in this embodiment can be any type of hinge structure. For example, two hinge shaft fixing sleeves are welded to the upper end face of the left side of the lower clamping plate 10, a hinge shaft is provided between the two hinge shaft fixing sleeves, and a hinge collar that can be rotatably connected to the hinge shaft is welded to the left end of the upper clamping plate 11. Example 2
[0037] The difference between this embodiment and embodiment 1 is that the electric drill support assembly and the clamping assembly are connected at an adjustable angle. The only difference between this embodiment and embodiment 1 is that the lower notch retaining ring 2 does not have a collar 19, and the inner connecting rod 5 is welded and fixed to the lower notch retaining ring 2.
[0038] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solution of this utility model and not to limit it. Although the utility model has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made to it in form and detail without departing from the scope defined by the claims of this utility model.
