[0016] 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 scope of protection of the present utility model.

[0017] Example

[0018] Please see Figure 1 , Figure 2 and Figure 3 This utility model provides a technical solution: a head locking structure for a splicing shovel, including a shovel head 1 and a handle 2. One end of the handle 2 is provided with a connecting groove, and the end of the shovel head 1 is provided with an installation rod. The installation rod is connected to the connecting groove. One end of the handle 2 is provided with an elastic annular pressure block 7. Specifically, the elastic annular pressure block 7 and the handle 2 are an integral structure. The outer thread of the elastic annular pressure block 7 is connected to a ring sleeve 8. The outer wall of the elastic annular pressure block 7 at one end of the shovel head 1 is inclined, and the outer diameter is smaller the closer it is to the shovel head 1. The inner wall of the ring sleeve 8 at one end of the shovel head 1 is inclined, and the inner diameter is smaller the closer it is to the shovel head 1. The first rod body 5 and the second rod body 6 are an integral structure, and the first groove body 3 and the second groove body 4 are an integral structure.

[0019] In this embodiment, after pushing the shovel head 1 to insert the mounting rod into the mounting groove at a certain position, the ring sleeve 8 is rotated to move the ring sleeve 8 and force the elastic annular pressure block 7 to deform in the direction of the mounting rod until it presses down on the mounting rod, thus completing the locking.

[0020] Furthermore, the connecting groove is provided with a first groove 3 and a second groove 4 from the inside to the outside. The inner diameter of the first groove 3 is smaller than that of the second groove 4. The mounting rod includes a first rod 5 and a second rod 6. The first rod 5 and the second rod 6 are respectively connected to the first groove 3 and the second groove 4.

[0021] In this embodiment, a gradient zone is formed at the connection between the first groove 3 and the second groove 4, which cooperates with the first rod 5 and the second rod 6 to produce a resisting and limiting effect.

[0022] Furthermore, the mounting rod is sleeved at the end of the shovel head 1.

[0023] In this embodiment, the mounting rod and the shovel head 1 can be connected by thread, welding or other fixed methods.

[0024] Furthermore, the contact surfaces of the elastic annular pressure block 7 and the ring sleeve 8 are provided with grooves and are connected to each other.

[0025] In this embodiment, the contact surfaces of the elastic annular pressure block 7 and the ring sleeve 8 are provided with grooves, thereby making the locking structure connection more stable.

[0026] 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.

[0027] The foregoing has shown and described the basic principles, main features, and advantages of this utility model.
