detailed description Embodiment 1, with reference to FIG. 1 and FIG. 2, a retractable bracket is provided, including two first connecting tubes 210, two second connecting tubes 220, two third connecting tubes 230, and two first locking mechanisms. 240, two second locking mechanisms 250, a first fixing member 260, a second fixing member 270, and an engaging base 280. The lower ends of the two first connecting tubes 210 are connected together by the first fixing member 260, the upper ends of the two second connecting tubes 220 are connected together by the second fixing member 270, and the upper ends of the two third connecting tubes 230 pass through the engaging base 280. connected.

Referring to Figures 1, 2, and 3, the first connecting pipe 210, the second connecting pipe 220, and the third connecting pipe 230 are each composed of two members having a "C"-shaped cross section, and the first connecting pipe 210 is exemplified below. For description, the first connecting pipe 210 is composed of two members 211 having a "C"-shaped cross section, and the members 211 of the "C"-shaped cross-section are plastic members, and their open sides are butted to form an accommodating space 212, "C"-shaped cross section. A connecting groove 213 is defined on both sides of the opening of the member 211, and is fixed by screw insertion into the connecting groove 213. The closing side of the "C" shaped member is provided with a locking seat 214 for fixing the first locking mechanism 240.

Thus, the two second connecting tubes 220 telescopically fit into the two first connecting tubes 210, and the two third connecting tubes 230 telescopically fit into the two second connecting tubes 220. A card slot 221 is disposed at a lower end portion of the two second connecting tubes 220, and a card slot 231 is disposed at a lower end portion of the two third connecting tubes 230. Referring to FIG. 4, the first locking mechanism 240 includes a base 241, a thimble 242, a spring 243, and a resisting plate 244. The base 241 is fixed to the locking seat 214 of the first connecting tube 210. The base 241 is further provided with a through hole 245 in the middle. The thimble 242 is inserted into the through hole 245, and the spring 243 is pressed against the ejector pin 242 to move the thimble 242 along the through hole 245. The other end of the spring 243 is pressed against the resisting plate 244, and the resisting plate 244 is fixed to the outside of the base 241. When the second connecting tube 220 is stretched upward, the second connecting tube 220 presses the thimble 242 into the through hole 245 of the base body, and when the locking groove 221 of the second connecting tube 220 corresponds to the thimble 242, the thimble 242 is in the spring. And protrude from the through hole 245 of the base 241 to be caught in the card slot 221, so that the second connecting pipe 220 is opposite to the first connecting pipe The 210 is fixed to achieve the stretchable function of the patent. When an external force is applied to the upper end of the second connecting tube 220, the second connecting tube 220 will push the thimble 242 into the through hole 245 of the base body, the thimble 242 and the card slot 221 start to be misaligned, and the second connecting tube 220 continues to be in an external force. The sleeve is inserted into the first connecting tube 210 to achieve the purpose of shrinking the patent.

The second locking mechanism 250 has the same structure as the first locking mechanism 240.

The first fixture 260 is comprised of two circular ferrules and a connector that connects the two circular ferrules together. Two circular ferrules are respectively sleeved and fixed at the lower ends of the two first connecting pipes 210 to stabilize the first connecting pipe 210.

The second fixing member 270 has the same structure as the first connecting member 260.

Referring to Fig. 5, the engaging base 280 has a support plate 282 extending vertically from a fixing plate 281. The fixing plate 281 is fixed to the upper ends of the two third connecting pipes 230, so that the third connecting pipe 230 and the second connecting pipe 220 are smoothly expanded and contracted.

When the present invention is applied to a related product of a retractable bracket, such as Santa Claus, the docking base 280 is used to support the shoulder and the head of Santa Claus, and the connecting base 280 can also be mounted with components such as a circuit board. The added function, the extended first connecting tube 210, the second connecting tube 220, and the third connecting tube 230 are used to support the body of Santa Claus. When it is necessary to pack Santa Claus in the package, a suitable external force is applied to press or tap the second connecting tube 220 to fit the first connecting tube 210, and the third connecting tube 230 to enter the second connecting tube 220. The size of Santa Claus can be made small, which reduces the cost of packaging, storage and transportation, and also increases the safety of the product. When used, the third connecting pipe 230 can be drawn, and the second connecting pipe 220 can be drawn. The first connecting tube 210 enables Santa to achieve the purpose of stretching and standing.

In the second embodiment, for the smaller volume, only one first connecting pipe 210 and one second connecting pipe 220 connected to the telescopic connection thereof may be used, and the second connecting pipe 220 has an engaging base at the upper end. 280, a first fixing member 260 is disposed at a lower end of the first connecting tube 210, and a first locking mechanism (240) is disposed between the first connecting tube 210 and the second connecting tube 220. The connecting tube and the locking mechanism of the embodiment The connection base structure is the same as the implementation one. The fixing member 260 is composed only of one circular ferrule.

The scope of application of the present invention relates to a telescoping bracket that can be used as an advertising telescoping bracket, and this embodiment is a preferred embodiment. In the course of implementation, the connecting tube can be designed as a round tube or other material, and the material used can be a carbon fiber material or other material. Any equivalent variations made in accordance with this patent application are within the scope of this patent.
