[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4 This utility model provides a technical solution: an adapter mounting and positioning device, comprising a cutter head cover 1, a drive structure, an elastic locking structure, a mechanical locking structure, and a cutter head body 10.

[0028] The drive structure is mounted on the cutter head cover 1 to drive the elastic snap-fit ​​mechanism. The elastic snap-fit ​​structure is mounted on the lower end of the drive structure to snap the cutter head body 10, thereby realizing the pre-assembly of the cutter head body 10.

[0029] The elastic locking structure is supported and limited by a mechanical locking structure, so as to achieve stable locking of the elastic locking structure onto the cutter head body 10.

[0030] The elastic locking mechanism includes two sets of reset members 7 and two sets of locking members 8 that are slidably disposed on the two sets of reset members 7, and the tool disc body 10 is pre-locked by the locking members 8;

[0031] The mechanical locking structure mainly consists of a cutter head adapter 9, which mechanically locks the two sets of locking components 8.

[0032] In this embodiment, as Figure 3 As shown, both sets of reset components 7 include a slide rod 71, a first spring 72, and two sets of second springs 73. The first spring 72 and the two sets of second springs 73 are all sleeved on the outside of the slide rod 71. The two sets of second springs 73 are respectively located at both ends of the slide rod 71, and the first spring 72 is located between the two sets of second springs 73. By placing the locking piece 8 between the first spring 72 and the two sets of second springs 73, the position of the two sets of second locking pieces 8 can be elastically adjusted, thereby facilitating the locking and reset of the two sets of locking pieces 8 on the cutter head body 10 and improving the efficiency of pre-positioning the cutter head body 10.

[0033] In a further preferred embodiment, such as Figure 3 As shown, the clip 8 includes a positioning block 81 made of an integral vehicle model and two sets of sliders 82. The two sets of sliders 82 are arranged on both sides of the positioning block 81, and the two sets of sliders 82 slide on the slide rods 71 ​​of the two sets of reset parts 7 respectively. The top view cross section of the positioning block 81 and the two sets of sliders 82 is convex. By setting the positions of the two sets of sliders 82 and the positioning block 81, the overall strength of the clip 8 is improved, thereby improving the service life of the clip 8.

[0034] Furthermore, such as Figure 3 As shown, an anti-detachment block 83 is integrally formed on one side of the positioning block 81. The side view of the anti-detachment block 83 is triangular. A first guide surface 84 is provided on the side of the anti-detachment block 83 opposite to the positioning block 81. A second guide surface 85 is provided on the other side of the positioning block 81 and the anti-detachment block 83. The first guide surface 84 is used to facilitate the positioning block 81 to quickly align with the alignment hole on the cutter head, thereby facilitating the quick insertion of the cutter head body 10.

[0035] Preferred, such as Figure 4As shown, the cutter head adapter 9 includes a pressure plate 91 and a locking bolt 96. An extension block 93 is fixedly connected to the pressure plate 91, and the extension block 93 has a stepped through hole 95 for the locking bolt 96 to be installed in a concealed manner. By inserting the locking bolt 96 into the stepped through hole 95, the cutter head adapter 9 can be easily installed on the drive structure, thereby improving the secondary fixation of the cutter head body 10 and improving the stability of the fixation of the cutter head body 10.

[0036] In addition, such as Figure 4 As shown, the lower surface of the pressure plate 91 is provided with a guide groove 92 for inserting two sets of clips 8. Both sides of the extension block 93 are provided with sliding grooves 94 for the second guide surface 85 to fit. The guide groove 92 is used to conveniently store the positioning block 81 of the clip 8, and the sliding groove 94 fits with the second guide surface 85 to limit the positioning block 81 of the two sets of clips 8, ensuring that the clip 8 limits the position of the cutter head body 10 and improving the stability of fixing the cutter head body 10.

[0037] Secondly, such as Figure 4 As shown, the upper surface of the cutter head body 10 has a center-mounted alignment hole for two sets of clamping parts 8 to pass through, and the cutter head body 10 has two sets of limiting holes. By opening the alignment hole in the center of the cutter head shaft, the installation of the cutter head body 10 is facilitated, the structural complexity of the cutter head body 10 is simplified, and the cost of the cutter head body 10 is reduced.

[0038] It is worth noting that, such as Figure 2-3 As shown, it also includes a connecting seat 6 driven by a drive mechanism. The lower surface of the connecting seat 6 has an installation groove 62 for installing two sets of reset pieces 7. The bottom of the installation groove 62 is fixedly connected to a threaded cylinder 65 for threaded connection of a locking bolt 96. The lower outer side of the connecting seat 6 is integrally formed with a reinforcing plate 63 that fits against the cutter head body 10. The lower surface of the reinforcing plate 63 is fixedly connected to a positioning rod 64 inserted into two sets of limiting holes. The reinforcing plate 63 increases the contact area with the cutter head body 10, thereby ensuring the stability of the cutter head body 10 installation. The positioning rod 64 can quickly position the cutter head body 10, improving installation efficiency.

[0039] At the same time, such as Figure 2-3As shown, the drive structure includes a drive motor 3 and a rotating shaft 4. The drive motor 3 is mounted on the upper surface of the cutter head cover 1. The rotating shaft 4 is rotatably connected to the top of the cutter head cover 1 and driven by the drive motor 3. The upper surface of the cutter head cover 1 is provided with a motor cover 2 to protect the drive motor 3. A limit ring 5 is provided on the outer side of the rotating shaft 4. The upper surface of the connecting seat 6 is provided with a threaded groove 61 for mounting the rotating shaft 4. The lower outer side of the rotating shaft 4 is provided with a connecting thread 41. The drive motor 3 drives the rotating shaft 4, which in turn facilitates the rotation of the connecting seat 6. The connecting seat 6 then drives the cutter head body 10, which is fixed by the clip 8 and the cutter head adapter 9, to rotate, thereby performing grass cutting work and improving the overall installation stability of the cutter head.

[0040] Finally, the open end plane of the cutter head cover 1 is higher than the horizontal height of the cutter head body 10, and the side view sections of the two sets of positioning blocks 81 are both set in right-angled trapezoids.

[0041] In use, align the alignment hole of the cutter head body 10 with the two sets of clips 8, so that the first guide surface 84 on the anti-detachment block 83 abuts against the alignment hole, thereby applying pressure to the cutter head body 10. Under the action of pressure, the two sets of anti-detachment blocks 83 will drive the positioning block 81 to compress the first spring 72, thereby bringing the two sets of positioning blocks 81 closer together so that the cutter head body 10 can be installed on the two sets of clips 8. After installation, the two sets of positioning blocks 81 prevent the cutter head body 10 from falling off through the anti-detachment block 83, while the positioning rod 64 is inserted into the limiting hole on the cutter head body 10 to prevent the cutter head body 10 from shaking.

[0042] Next, the guide groove 92 of the cutter head adapter 9 is connected to the two sets of positioning blocks 81, so that the sliding groove 94 on the extension block 93 fits with the second guide surface 85 on the positioning block 81. The locking bolt 96 is tightened by passing through the stepped through hole 95 and connecting to the threaded cylinder 65, so that the cutter head adapter 9 can press the cutter head body 10 onto the reinforcing plate 63, which improves the stability of the installation of the cutter head body 10. The extension block 93 can limit the two sets of clamps 8, thereby preventing the clamps 8 from loosening, achieving a double positioning effect, thus improving the applicability of the cutter head installation.

[0043] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
