Detailed Description
The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
Embodiment one:
as shown in fig. 1, a complete shovel is shown, which comprises a shovel head 2 and a long rod-shaped shovel rod, wherein the shovel rod in the embodiment is divided into two sections, namely a lower rod 1 and an upper rod 4, and the lower rod 1 and the upper rod 4 are detachably connected, so that the shovel is assembled when in use, detached when not in use, and is convenient to carry and store. The shovel head 2 is fixedly arranged at the bottom end of the lower rod 1.
As shown in fig. 2 and fig. 3 together, the upper end of the lower rod 1 is sleeved with a cylindrical lower connecting sleeve 3, the two are in interference fit, and after the two are matched, the outer wall of the lower connecting sleeve 3 is aligned with the outer wall of the lower rod 1, so that the comfort level in use can be improved. The lower connecting sleeve 3 is also penetrated with a cylindrical fixing pin 6, the fixing pin 6 penetrates through the outer wall of the lower connecting sleeve 3 and is embedded into the lower rod 1 to a certain depth, and the outer end surface of the fixing pin 6 is also aligned with the outer wall of the lower connecting sleeve 3, so that the comfort level in use is also improved. On the other hand, the extension line of the central axis of the fixing pin 6 passes through the central axis of the lower rod 1, so that the stress can be more uniform.
The structure of the upper rod 4 is basically the same as that of the lower rod 1, and the upper rod 4 is also sleeved with an upper connecting sleeve 5, and a fixing pin 6 is also penetrated through the upper connecting sleeve. The outer wall of the upper connecting sleeve 5 is provided with external threads 8, and the corresponding inner part of the lower connecting sleeve 3 is provided with internal threads 7, so that the connection between the lower rod 1 and the upper rod 4 can be realized by utilizing the external threads 8 and the internal threads 7.
