[0026] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.
[0027] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.
[0028] Please refer to the attached Figure 1 To Attachment Figure 4 The utility model describes a tool connection assembly and a multifunctional shovel.
[0029] At present, the tools used can be divided into three parts, namely, tool rods, tool connecting components and tool working parts; among them, tool rods are used for manual grasping, and common tool rods are handle parts of a series of tools such as shovel handles and pickaxe handles; tool connecting components are used to connect tool rods and tool working parts; tool working parts are used to operate on the objects to be operated, such as shovel blades, pickaxe heads, etc., and common operating scenes are agricultural operations, construction, gardening activities, cleaning work, survival in the wild, etc.; common objects to be operated are soil, gravel, coal, etc.; common tool working parts are shovel blades, pickaxe heads, rake heads, etc.
[0030] At present, in the prior art, the limit piece of the tool connection assembly is passed through the back of the tool working part, so that when the tool is in use, the tool connection assembly may interfere with soil or sand and gravel, which may cause damage to the tool connection assembly. In addition, when the shovel is shoveling or digging downwards, the tool working part cannot be fully used, affecting work efficiency.
[0031] Therefore, the tool connecting assembly includes a matching body 1 connected to the tool rod and a clamping wheel 3 connected to the tool working piece. The clamping wheel 3 can rotate relative to the matching body 1, so that the angle between the tool working piece and the tool rod can be changed, so that different working methods can be selected between different working scenes and different objects to be worked, that is, different angles between the tool working piece and the tool rod.
[0032] Preferably, the angle between the tool rod and the tool working piece is about 180 degrees. At this time, the tool working piece and the tool rod are on the same plane, and a common way of using them is to shovel and dig the work object; the angle between the tool rod and the tool working piece is about 90 degrees. At this time, the tool working piece and the tool rod are close to a vertical state, and a common way of using them is to plan and hoe the work object; in other embodiments of the utility model, the angle between the tool rod and the tool working piece can also be adjusted arbitrarily between 90 degrees and 180 degrees, as long as the work needs can be met.
[0033] Regarding the rotational connection method between the card wheel 3 and the matching body 1, it is preferably connected through a rotating shaft 11. A rotating groove is opened on the matching body 1, and the rotating shaft 11 is rotationally connected to the card wheel 3 through the rotating groove. The rotating shaft 11 is fixedly connected to the card wheel 3. In other embodiments of the utility model, the rotational connection can also be carried out through a pin shaft, a rotating part, etc., as long as the rotational connection between the card wheel 3 and the matching body 1 can be satisfied.
[0034] Regarding the rotational position of the clamping wheel 3 and the mating body 1, it is preferred that a groove 13 is opened on the mating body 1, and the clamping wheel 3 is rotatably connected to the groove 13 of the mating body 1 through the rotating shaft 11. In other embodiments of the utility model, the clamping wheel 3 can also be directly rotatably connected to the mating body 1, as long as the clamping wheel 3 and the mating body 1 can be rotatably connected.
[0035] The groove 13 is a groove open on both sides, and a first limit surface and a second limit surface are provided on the groove 13. The first limit surface and the second limit surface are located on opposite sides of the open end of the groove 13. When the angle between the tool rod and the tool working part is about 180 degrees, the clamping wheel 3 is at odds with the first limit surface, so that the clamping wheel 3 cannot continue to rotate to an angle outside 180 degrees. When the angle between the tool rod and the tool working part is about 90 degrees, the clamping wheel 3 is at odds with the second limit surface, so that the clamping wheel 3 cannot continue to rotate to an angle within 90 degrees.
[0036] A connecting plate 32 is fixedly connected to the clamping wheel 3, and one end of the connecting plate 32 away from the clamping wheel 3 is fixedly connected to the tool working piece, and the clamping wheel 3 is located at the top of the connection between the connecting plate 32 and the tool working piece, so that when the tool is in use, the connection between the tool connecting component and the tool working piece is located at the top of the tool working piece, and the part of the tool connecting component located on the tool working piece is relatively small, so that when the tool is in use, the tool connecting component reduces interference with the object to be worked on, avoiding damage to the tool connecting component, and when the tool is shoveling or digging downwards, the tool working piece can be almost fully used, thereby improving work efficiency.
[0037] Regarding the connection method between the connecting plate 32 and the tool working piece, riveting is preferred to improve the connection strength between the tool working piece and the tool connecting assembly, and it is also aesthetically pleasing. In other embodiments of the utility model, welding fixation or bolt fixation can also be used, as long as the connection plate 32 and the tool working piece can be fixed.
[0038] A limit piece 2 is provided on the matching body 1, and the limit piece 2 can be clamped with the clamping wheel 3. The limit piece 2 is located at the opposite end of the clamping wheel 3, and the limit piece 2 has a limiting state and a separation state: when the limit piece 2 is in the limiting state, the limit piece 2 is clamped with the clamping wheel 3, and the clamping wheel 3 is fixedly limited, so that the angle between the tool rod and the tool working part is fixed and cannot be rotated; when the limit piece 2 is in the separation state, the limit piece 2 and the clamping wheel 3 are cancelled, so that the clamping wheel 3 can be rotated relative to the matching body 1, so that the angle between the tool rod and the tool working part can be adjusted by rotation.
[0039] Furthermore, by arranging the limiter 2 on the matching body 1, when the tool is in use, the limiter 2 reduces interference with the work object, thereby avoiding damage to the limiter 2. When the tool is shoveling or digging downward, almost all of the tool working parts can be used, thereby improving work efficiency.
[0040] Regarding the limiting method between the limit member 2 and the clamping wheel 3, it is preferred that a screw hole 12 is opened on the matching body 1, the screw hole 12 is connected to the groove 13, and a threaded groove 21 is opened on the limit member 2. The screw hole 12 on the matching body 1 is threadedly connected to the limit member 2. When the limit member 2 is in the limiting state, the limit member 2 is screwed, and the limit member 2 enters the groove 13 through the screw hole 12 until it is clamped with the clamping wheel 3 in the groove 13 to ensure that the tool working part and the tool rod part cannot rotate. In other embodiments of the utility model, a through hole may also be opened on the matching body 1, and the limit member 2 is slidably connected to the through hole. The limit member 2 is clamped with the clamping wheel 3 in the groove 13 by pressing the limit member 2, and then the position of the limit member 2 can be fixed by a clamping tool.
[0041] Preferably, a clamping groove 31 is provided on the clamping wheel 3 , and a clamping block matching the shape of the clamping groove 31 is provided at the end of the limiting member 2 , so as to further improve the clamping effect between the limiting member 2 and the clamping wheel 3 .
[0042] The shape of the slot 31 is preferably conical, and the shape of the end of the limit member 2 is also conical. In other embodiments of the utility model, the slot 31 can also be cylindrical, rectangular, etc., as long as the clamping effect between the end of the limit member 2 and the slot 31 can be guaranteed.
[0043] Regarding the number of the card slots 31, it is no less than two, that is, at least two, so as to ensure the fixation effect when the tool rod and the tool working piece are about 180 degrees and when the tool rod and the tool working piece are about 90 degrees. The number of the card slots 31 can be determined according to actual conditions.
[0044] Also disclosed is a multifunctional shovel, which includes a shovel rod 4 and a shovel plate 5. The shovel rod 4 is detachably connected to the matching body 1, so that it is convenient to carry after disassembly. The shovel rod 4 can also be composed of multiple connecting rods, which are detachably connected to each other, and are also convenient to carry after disassembly. The shovel plate 5 is riveted to the connecting plate 32 by rivets to form a complete shovel body.
[0045] The end of the shovel plate 5 is provided with arched folds 51, so as to facilitate the insertion of the shovel plate 5 into the soil when working on harder soil and to enhance the strength of the shovel plate 5. The side edge of the shovel plate 5 is provided with a serrated structure.
[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the claims of the present invention.
