Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] Embodiment 1

[0024] See also Figure 1-5The utility model provides a technical solution: a six-petal grab bucket that is easy to maintain, comprising a sleeve 1 and a slide bar 2, a mounting seat 3 is fixedly installed at the bottom end of the slide bar 2, a fixed shaft 4 is evenly fixedly installed inside the mounting seat 3, a fixing plate 5 is evenly fixedly installed on the outer wall of the sleeve 1, connecting plates 6 are installed on both sides of the fixing plate 5, an axial hole 7 is opened inside the connecting plate 6 and the fixing plate 5, an axial pin 8 is rotatably connected inside the axial hole 7, and a grab bucket petal body 9 is installed on the inner side of the bottom of the connecting plate 6, An axial hole 10 is provided inside the grab bucket body 9 and the connecting plate 6, and an axial pin 11 is rotatably connected inside the axial hole 10. A plug hole 12 is provided at the bottom end of the grab bucket body 9, and a plug column 13 is slidably connected inside the plug hole 12. A grab bucket tooth tip 14 is fixedly installed on the end of the plug column 13 away from the plug hole 12. Screw holes 15 are provided inside the grab bucket body 9 and the plug column 13, and a bolt 16 is threadedly connected inside the screw hole 15, and a screw block 17 is fixedly installed on the end of the bolt 16 away from the screw hole 15. By setting up structures such as the socket 12, the column 13, the screw hole 15, the bolt 16 and the screw block 17, the screw block 17 drives the bolt 16 to rotate inside the screw hole 15. After rotating a certain number of circles, the bolt 16 is removed, and then the grab tooth tip 14 together with the column 13 is taken out from the inside of the socket 12 for replacement. This structure can disassemble the worn grab tooth tip 14, thereby making it convenient for the staff to replace the worn grab tooth tip 14, and effectively avoiding the situation that the grab tooth tip 14 cannot be disassembled and replaced after being worn, which will reduce the use effect of the six-petal grab.

[0025] See also Figure 1-5 The fixing plate 5 is rotationally connected to the connecting plate 6, and the adjustment effect of the connecting plate 6 is improved by the rotational connection. The grab valve body 9 is rotationally connected to the connecting plate 6, and the grab valve body 9 is rotationally connected to the fixed shaft 4, and the adjustment effect of the grab valve body 9 is improved by the rotational connection. The sleeve 1 is slidingly connected to the slide rod 2, and the adjustment effect of the slide rod 2 is improved by the sliding connection. The inner surface of the grab tooth tip 14 is evenly fixedly installed with an anti-slip strip 20, and the anti-slip effect of the grab tooth tip 14 when grasping an object is improved by the anti-slip strip 20.

[0026] Embodiment 2

[0027] See also Figure 5A limiting circular block 18 is fixedly installed on the top of the slide bar 2, and the limiting circular block 18 improves the limiting effect of the reset spring 19. The top outer wall of the slide bar 2 is sleeved with a reset spring 19, and the six-petal grab can be quickly opened or closed by the reset spring 19. The reset spring 19 is slidably connected to the slide bar 2, and the use effect of the reset spring 19 is improved by the sliding connection. By setting structures such as the limiting circular block 18 and the reset spring 19, the limiting circular block 18 can be pressed downward to squeeze the reset spring 19, and the six-petal grab can be opened after squeezing a certain distance, and the six-petal grab can be closed by releasing the limiting circular block 18. This structure can quickly open or close the six-petal grab, thereby making it convenient for the staff to use.

[0028] Working principle: When using the six-petal grab, first press the limiting round block 18 downward so that the limiting round block 18 squeezes the reset spring 19 downward. In the process of squeezing the reset spring 19 downward, the limiting round block 18 will drive the slide bar 2 to slide downward inside the sleeve 1. In the process of sliding downward, the slide bar 2 will drive the mounting seat 3 to slide downward together. In the process of sliding downward, the mounting seat 3 will drive the six groups of grab petal bodies 9 to rotate on the outer walls of the six groups of fixed shafts 4. At the same time, the six groups of grab petal bodies 9 will also rotate on the outer walls of the six groups of axle pins 2 11 and the inner sides of the six groups of connecting plates 6, and the six groups of connecting plates 6 will also rotate on the outer walls of the axle pins 1 8. After rotating a certain angle, the six groups of grab petal bodies 9 will drive the six groups of grab tooth tips 14 to be in an open state. When the limiting round block 18 is released, the reset spring 19 will close the six groups of grab petal bodies 9 and the six groups of grab tooth tips 14. When the six-petal grab bucket is used for a long time and causes the grab bucket tooth tip 14 to wear, a tool can be used to twist the screw block 17, which drives the bolt 16 to rotate inside the screw hole 15. After rotating it a certain number of times, the bolt 16 can be removed, and then the grab bucket tooth tip 14 and the plug column 13 can be taken out from the inside of the socket 12 for replacement.

[0029] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
