[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0020] Example
[0021] Please see Figure 1 , Figure 2 and Figure 3This utility model provides a technical solution: a tail locking structure for a combined shovel, including a shovel head 1, a tube body 2 and a tail 3, the shovel head 1, tube body 2 and tail 3 are arranged sequentially from left to right, the two ends of the tube body 2 are provided with mounting cavities 6, the mounting cavities 6 are provided sequentially from left to right with a first connecting cavity 61, a second connecting cavity 62 and a third connecting cavity 64, the second connecting cavity 62 is provided with an annular locking block 9 inside, the annular locking block 9 is made of elastic material, a first annular groove 63 is formed between the side wall of the annular locking block 9 and the side wall of the second connecting cavity 62, the inner diameter of the first connecting cavity 61 is larger than the inner diameter of the second connecting cavity 62;
[0022] The end of the shovel head 1 is provided with a connecting rod 4. The connecting rod 4 is provided with a first connecting block 41, a second connecting block 42 and a third connecting block 43 from left to right. The diameter of the second connecting block 42 is larger than that of the third connecting block 43. The second connecting block 42 is adapted to the first connecting cavity 61. The side wall of the third connecting block 43 is provided with a slot 44, which is adapted to the annular slot 9.
[0023] One end of the tail section 3 is connected to a sleeve 8, which passes through the third connecting cavity 64 and extends into the interior of the first annular groove 63.
[0024] In this embodiment, pushing the shovel head 1 causes the connecting rod 4 to be inserted into the mounting cavity 6. When the third connecting block 43 passes the position of the annular locking block 9, it pushes the annular locking block 9 to move upward. The annular locking block 9 is made of elastic material and deforms. When the slot 44 moves to the position of the annular locking block 9, the annular locking block 9 returns to its initial position and is locked inside the slot 44. Then, the sleeve 8 passes through the third connecting cavity 64 and extends into the interior of the first annular groove 63. The sleeve 8 prevents the annular locking block 9 from having enough space to undergo elastic deformation, thus preventing the shovel head 1 from being pulled out. At the same time, the end of the second connecting block 42 abuts against the connection between the first connecting cavity 61 and the second connecting cavity 62, forming a limiting structure.
[0025] Furthermore, the first connecting block 41, the second connecting block 42 and the third connecting block 43 are an integral structure. The diameter of the first connecting block 41 is larger than the inner diameter of the first connecting cavity 61, and one end of the first connecting block 41 abuts against the end of the tube body 2.
[0026] In this embodiment, the first connecting block 41 and the tube body 2 form a limiting structure.
[0027] Furthermore, the outer wall of the sleeve 8 is threadedly connected to the third connecting cavity 64, and the sleeve 8 can be driven to move along the third connecting cavity 64 by rotating the tail 3.
[0028] In this embodiment, the outer wall of the sleeve 8 is threadedly connected to the third connecting cavity 64, thereby maintaining the position of the sleeve 8 and facilitating locking.
[0029] Furthermore, the first connecting block 41 and the second connecting block 42 are both provided with a mounting slot 5, and the shovel head 1 is connected to the mounting slot 5.
[0030] In this embodiment, the shovel head 1 and the mounting slot 5 can be connected by threads, welding or other fixed connections. The mounting slot 5 allows the shovel head 1 to be stably connected to the connecting rod 4.
[0031] Furthermore, a second annular groove 7 is provided at one end of the tail section 3, and the second annular groove 7 is fitted onto the tube body 2.
[0032] In this embodiment, the second annular groove 7 is fitted onto the tube body 2, making the connection between the tail 3 and the tube body 2 aesthetically pleasing.
[0033] Furthermore, one end of the tail 3 extends into the interior of the sleeve 8.
[0034] In this embodiment, the tail 3 and the sleeve 8 can be connected by threads, welding or other fixed connections. One end of the tail 3 extends into the interior of the sleeve 8 to facilitate the movement of the sleeve 8.
[0035] The working principle and usage process of this utility model: After the utility model is installed, work according to the above implementation method until all working steps are completed.
