[0016] The following description, in conjunction with the accompanying drawings, further illustrates the proposed solution:
[0017] See appendix Figure 1-12 An angle-adjustable outdoor garden scissors sharpener includes a sharpening base 1, a sharpening assembly mounted on the sharpening base 1, a rotating shaft 4, a drive wheel 3, and a positioning assembly 5.
[0018] The grinding assembly includes a rotating base 2; the grinding base 1 is provided with a mounting groove 11, and the rotating base 2 is rotatably installed in the mounting groove 11; the rotating base 2 is provided with a plurality of grinding holes 21 with different grinding precisions, and each grinding hole 21 is evenly spaced around the rotation axis L of the rotating base 2; the drive wheel 3 is rotatably installed on the grinding base 1, and the drive wheel 3 is connected to the rotating base 2 so as to drive the rotating base 2 to rotate when the drive wheel 3 rotates.
[0019] This technical solution centrally sets various grinding edges 21 of different precision on the rotating base 2, which is lightweight, small in size, and easy to carry. By rotating the rotating base 2, the position of the grinding edge 21 relative to the sharpening base 1 can be adjusted to switch between different grinding edges 21 for use, which is flexible and convenient and meets different sharpening needs. It is suitable for both straight-blade garden shears and curved-blade garden shears.
[0020] The positioning component 5 is used to fix the rotation angle of the drive wheel 3.
[0021] The drive wheel 3 is provided with a plurality of positioning grooves 31, and the positioning grooves 31 are evenly spaced around the rotation axis L of the drive wheel 3. The positioning component 5 includes a positioning slider 51; the grinding seat 1 is provided with a sliding groove 12 on one side of the drive wheel 3, and the positioning slider 51 is slidably installed in the sliding groove 12 along the radial direction of the drive wheel 3 to switch between a locked state and an unlocked state.
[0022] The positioning slider 51 is provided with a positioning protrusion 511. When the positioning slider 51 is in the locked state, the positioning protrusion 511 falls into one of the positioning grooves 31 to restrict the rotation of the drive wheel 3, thereby fixing the rotation angle of the drive wheel 3 and the rotating wheel. When the positioning slider 51 is in the unlocked state, the positioning protrusion 511 disengages from the positioning groove 31 to release the restriction on the drive wheel 3.
[0023] This technical solution ensures the stability of the grinding tool by setting a positioning slider 51 to lock the rotation angle of the drive wheel 3 and the rotating seat 2. It is simple to operate and easy to implement.
[0024] The positioning component 5 also includes a compression spring 52; the bottom of the slide groove 12 is provided with a travel groove 13, the travel groove 13 includes a front wall 131 and a rear wall 132 spaced apart along the sliding direction of the positioning slider 51; a limiting block 53 is provided on the inner side of the positioning slider 51, the limiting block 53 is slidably installed in the travel groove 13; the compression spring 52 is sandwiched between the limiting block 53 and the rear wall 132; when the positioning slider 51 is in the locked state, the limiting block 53 abuts against the front wall 131 to limit the sliding travel of the positioning slider 51.
[0025] In this embodiment, the limiting block 53 is connected and fixed to the positioning slider 51 by the first screw 54. During installation, the limiting block 53 and the compression spring 52 are first placed into the stroke groove 13, then the positioning slider 51 is placed into the slide groove 12, and then the first screw 54 is used to connect the positioning slider 51 and the limiting block 53.
[0026] In use, by moving the positioning slider 51 away from the drive wheel 3, the positioning protrusion 511 disengages from the positioning groove 31, thus switching to the unlocked state. Figure 12 As shown; the positioning slider 51 is released, and under the action of the compression spring 52, it slides towards the drive wheel 3, causing the positioning protrusion 511 to fall into the positioning groove 31, thus locking the drive wheel 3, as shown. Figure 11 As shown.
[0027] The positioning slider 51 is provided with a toggle key 512 extending out of the slide groove 12, which facilitates the gripping and sliding of the positioning slider 51.
[0028] The mounting groove 11 includes a first groove wall 111 and a second groove wall 112. The grinding base 1 is provided with a first shaft hole 113 penetrating the first groove wall 111 and a second shaft hole 114 penetrating the second groove wall 112. The rotating base 2 is provided with a central hole 23 penetrating both ends. The rotating shaft 4 is sequentially inserted into the first shaft hole 113 and the central hole 23 and can rotate relative to the first shaft hole 113. The drive wheel 3 is provided with a shaft connection part 32, which is sequentially inserted into the second shaft hole 114 and the central hole 23 and can rotate relative to the second shaft hole 114. The shaft connection part 32 and the end of the rotating shaft 4 are screwed and fixed in the central hole 23. Specifically, the end of the rotating shaft 4 is provided with an external thread 41, and the shaft connection part 32 is provided with a threaded hole 322. The end of the rotating shaft 4 is screwed into the threaded hole 322.
[0029] The hole wall at one end of the central hole 23 through which the shaft connection part 32 passes is provided with a hole limiting plane 231, and the shaft connection part 32 is provided with a wheel limiting plane 321. The hole limiting plane 231 and the wheel limiting plane 321 are parallel and abut against each other to restrict the drive wheel 3 from rotating relative to the rotating seat 2, that is, the drive wheel 3 is fixed relative to the rotating seat 2.
[0030] This technical solution uses a rotating shaft 4 and a drive wheel 3 shaft connection 32 screwed together to form a rotating shaft that rotatably engages with the grinding seat 1. The rotating seat 2 is installed on the rotating shaft composed of the rotating shaft 4 and the drive wheel 3 to achieve rotatable engagement with the grinding seat 1.
[0031] This technical solution uses the wheel rotation limiting plane 321 and the hole rotation limiting plane 231 to limit the movement, so that the drive wheel 3 is fixed relative to the rotating seat 2, thereby driving the rotating seat 2 to rotate when the drive wheel 3 rotates.
[0032] No additional screws are needed to fix the shaft 4, drive wheel 3 and grinding base 1, the shaft 4 and drive wheel 3, and the drive wheel 3 and rotating base 2, making installation and disassembly convenient.
[0033] Each grinding port 21 of the rotating base 2 is equipped with a grinding disc assembly; each grinding disc assembly consists of two grinding discs 24 arranged at a certain angle, and different angles result in different grinding precision.
[0034] This technical solution uses grinding discs with different angles to finely grind or polish the blades of various garden scissors.
[0035] The rotating base 2 is provided with a plurality of sharpening parts 22; each sharpening part 22 is evenly spaced around the rotation axis L of the rotating base 2;
[0036] Each grinding end 21 is respectively provided on each grinding section 22. The grinding section 22 is provided with a countersink 221, and the grinding disc 24 is fixed in the countersink 221 by a second screw 25.
[0037] In this embodiment, there are three grinding ports 21, which are used for coarse grinding, fine grinding and polishing respectively. The number of grinding blades 22 and grinding discs corresponds to the number of grinding ports 21.
[0038] Each grinding section 22 and the drive wheel 3 are equipped with corresponding grinding precision markings.
[0039] In this technical solution, the grinding disc 24 is fixed to the grinding head 22 by the second screw 25 and can be disassembled for replacement.
[0040] The grinding base 1 is formed on a handle 14, which is convenient for holding and fixing. The grinding base 1 and the handle 14 are integrally formed, without the need for additional connecting structures, which facilitates production.
[0041] The above preferred embodiments should be regarded as illustrative examples of the embodiments of the present application. Any technical deductions, substitutions, improvements, etc. that are similar to or based on the present application should be considered within the scope of protection of this patent.
