The lower end of the riser 2 is sleeved on the vertical pole 1 and fixedly connected thereto. The vertical pole 1, the riser 2 and the support plate 3 are an integrated structure.

[0030] The head support 6 includes a sleeve 10, a supporting wing 11, a wing tip 12, and two groups of ninety-degree arc-shaped convex clamping positions 18. The sleeve 10 is sleeved on the outside of the vertical tube 2 and the supporting wings 11 are respectively placed on both sides of the sleeve 10 and fixedly connected thereto. The wing tip 12 is placed at the end of the supporting wing 11 and fixedly connected thereto, and a hollow 17 is provided on the supporting wing 11, and the wing tip 12 is a curved step structure.

[0033] The principle of the simple early head removal device of the utility model is:

[0034] During installation, if Figure 2 As shown, align the circular mouth of the head support pin with the circular groove of the tube clamp slot 1 of the riser, then insert the clamp pin from the circular mouth of the pin on one side of the head support through the circular groove of the tube clamp slot 1 to extend to the outside of the head support, and then insert the pin into the pin hole. At this time, the pin is just stuck in the notch of the 90-degree arc-shaped convex clamping position to limit the head support. Similarly, rotate the head support, align the circular mouth of the head support pin with the circular groove of the tube clamp slot 2 of the riser, and then install it to the circular groove position of the tube clamp slot 2. The height positions of the tube clamp slot 1 and the tube clamp slot 2 on the riser are different, so the height of the installed head support is different, and the disassembly is based on the same principle.

[0035] like Figure 6 As shown, this is the position diagram of the internal bayonet after the above installation. As described in 7, when using, rotate the bayonet to the position shown in the figure. At this time, the two ends of the pin column are close to the side of the ninety-degree arc-shaped convex clamping position, and the pin column falls from the pin hole. The wall thickness position of the vertical pipe at the position of the pipe clamping groove is in the pin groove. The clamping column drives the support head to slide down from the pipe clamping groove and fall to its bottom, completing the disassembly.

[0036] The utility model is easy to operate and has a simple structure through the arrangement of the limiting components, and is convenient for installation and disassembly of the head support.

[0037] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
