[0031] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0032] The specific embodiments described below are merely preferred embodiments of this application, and the scope of protection of this application is not limited thereto. Those skilled in the art can make modifications or variations based on the principles, concepts, and spirit of this application, and the resulting technical solutions should all be covered within the scope of protection of this application.

[0033] like Figures 1-8 As shown, the buckle seat 3 is a plastic part made of nylon and glass fiber. During the production process, the first copper insert 9 and the second copper insert 10 are integrated with the buckle seat 3 by injection molding (achieving a fixed connection between the first copper insert 9, the second copper insert 10 and the buckle seat 3). The buckle seat 3 is fitted onto the outer tube 1 and fixed by adhesive. The buckle seat 3 has an axial through hole 3-1, a window 3-2, a first rivet pin connection part 3-3, and a second rivet pin connection part 3-4. The window 3-2 communicates with the axial through hole 3-1. The first rivet pin connection part 3-3 has a copper insert insertion hole 3-3-1, and the second rivet pin connection part 3-4 also has a copper insert insertion hole. The first copper insert 9 is located in the copper insert insertion hole 3-3-1, and the second copper insert 10 is located in the copper insert insertion hole of the second rivet pin connection part 3-4. The pressing plate 4 has two connection holes 4-1 on both sides; the end of the pressing plate 4 has a hook 4-2. First, place the torsion spring 6 between the first rivet pin connection part 3-3 and the second rivet pin connection part 3-4 of the buckle seat 3, then fasten the pressing plate 4. Pass the rivet pin 7 through the first copper insert 9, the torsion spring 6, the two connecting holes on the pressing plate 4, and the second copper insert 10 in sequence. Then, screw the rivet screw 8 into the end of the rivet pin 7. Under the action of the torsion spring 6, the pressing plate 4 is in a raised state, that is, the rear end of the pressing plate 4 is raised in the initial state.

[0034] The middle part of the inner tube one 5 is provided with a clamping groove 5-1, the inner tube two 2 is sleeved on the inner tube one 5 and is fixed by glue, the inner tube two 2 and the inner tube one 5 are fixedly connected to form an inner tube assembly, the front end face of the inner tube one 5 is away from the front end face of the inner tube two 2 by a certain distance, and a spring accommodating cavity 2-1 is formed. The spring 12 is placed in the spring accommodating cavity 2-1, one end of the spring 12 is in contact with the front end face of the inner tube one 5, the inner tube gasket 13 is in contact with the other end of the spring 12, and the inner tube gasket 13 is placed in the spring accommodating cavity 2-1. The pressing plate 4 is pressed by fingers, the clamping hook 4-2 at the end of the pressing plate 4 is lifted, then the inner tube assembly is inserted into the outer tube 1 through the axial through hole 3-1 of the buckle seat 3, when the inner tube assembly is pushed to the position that the clamping groove 5-1 of the inner tube one 5 is located at the window 3-2 and the clamping groove 5-1 is aligned with the clamping hook 4-2 at the front end of the pressing plate 4 in the outer tube 1, the pressing plate 4 is loosened, and the clamping hook 4-2 at the end of the pressing plate 4 is embedded in the clamping groove 5-1, at this time, the inner tube assembly and the outer tube are in the locked state (the inner tube assembly and the outer tube cannot move relative to each other). The pull wire 14 passes through the inner tube assembly, the spring 12 and the outer tube 1, the outer tube gasket 11 is fixedly connected to the rear end of the outer tube 1, the outer tube gasket 11 is provided with a connecting hole, the rear end of the pull wire 14 passes through the connecting hole and is knotted to position the rear end of the pull wire 14, and the inner tube gasket 13 is provided with a connecting hole, the front end of the pull wire 14 passes through the connecting hole of the inner tube gasket 13 and is knotted to position the front end of the pull wire 14.

[0035] When the inner tube assembly and the outer tube 1 are in the locked state, the spring 12 is compressed, and the pull wire 14 is in a tight state. At this time, the pressing plate 4 is pressed to lift the clamping hook 4-2 at the end of the pressing plate 4, the clamping hook 4-2 at the end of the pressing plate 4 is separated from the clamping groove 5-1 of the inner tube one 5, and under the action of the elastic force of the spring 12, the inner tube assembly moves backward to automatically retract into the outer tube 1 by a distance, at this time, the inner tube assembly and the outer tube 1 are in the retracted state. When the inner tube assembly and the outer tube 1 are in the retracted state, the pull wire 14 is in a relaxed state.

[0036] When it is necessary to stretch the inner tube assembly and the outer tube 1 in the retracted state, the inner tube assembly is pulled out of the outer tube (the inner tube assembly moves forward), when the inner tube assembly is pulled out by a certain length, the clamping hook 4-2 at the end of the pressing plate 4 is embedded in the clamping groove 5-1 of the inner tube one 5, at this time, the inner tube assembly and the outer tube 1 are in the locked state.

[0037] It can be seen that the operation of pulling out the inner tube assembly from the outer tube is quick and convenient, and the operation of retracting the inner tube assembly into the outer tube is also quick and convenient. After the inner tube assembly is pulled out of the outer tube, the connection strength between the inner tube assembly and the outer tube is high, and the safety is good. The pressing plate 4 is operated by fingers, the operation is convenient, the hand feeling is good, and the hand feeling is comfortable.

[0038] It can be seen that the manufacturing process is convenient.

[0039] It should be noted that the material of the pressing plate 4 can be stainless steel.

[0040] It should be noted that the pull wire 14 can be specifically selected to use a strong horse line.

[0041] It should be noted that the material of the outer tube gasket 11 can be stainless steel, and the material of the inner tube gasket 13 can be stainless steel.

[0042] It should be noted that the material of the buckle seat 3 is not limited to nylon plastic with glass fiber.

[0043] As shown in the drawings, the edge of the clamping hook 4-2 of the pressing plate 4 is a circular arc shape, and the clamping groove 5-1 of the inner tube 5 is a ring-shaped clamping groove. It is a preferred design to match the circular arc-shaped edge with the ring-shaped clamping groove 5-1, and it is not the only limited structure design. Those skilled in the art can understand that the clamping groove 5-1 can also be a circular arc shape, and the circular arc-shaped clamping groove 5-1 matches the circular arc-shaped edge of the clamping hook 4-2. Those skilled in the art can also understand that the edge of the clamping hook 4-2 can also be other shapes, and the clamping groove of the inner tube 5 can also be other shapes that can match the edge of the clamping hook 4-2.
