[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 3 , a sleeve expansion device for clamping a plastic pipe plug in this embodiment, includes a fixed seat 1, and an adjusting and fastening mechanism is arranged at the top of the fixed seat 1.

[0022] In this embodiment, the adjusting and fastening mechanism includes a lower clamping plate 2 fixedly installed at the top of the fixed seat 1. The upper clamping plate 3 is hinged to the top of the lower clamping plate 2. Fixing plates 4 are fixedly installed on one side of the lower clamping plate 2 and the upper clamping plate 3 respectively. A fixing bolt 5 is threadedly connected inside the fixing plate 4. Thread grooves are opened inside both fixing plates 4. The fixing bolt 5 is threadedly connected to the fixing plate 4 through the thread groove, which helps to limit and fix and loosen the lower clamping plate 2 and the upper clamping plate 3 by using the fixing bolt 5.

[0023] Among them, a buffer pad 6 is fixedly installed inside the lower clamping plate 2. The top of the buffer pad 6 is movably connected to the pipe body 7. A fastening screw 8 is threadedly connected inside the lower clamping plate 2 and the upper clamping plate 3. Identical fastening grooves are opened inside the lower clamping plate 2 and the upper clamping plate 3. The fastening screw 8 is movably connected to the lower clamping plate 2 and the upper clamping plate 3 through the fastening groove, which is convenient for combining and using the two devices. A fixing frame 9 is fixedly installed at the top of the upper clamping plate 3, and an adjusting and fixing component is arranged inside the fixing frame 9.

[0024] In this embodiment, the adjusting and fixing component includes an adjusting screw 10 threadedly connected inside the fixing frame 9. A threaded hole is opened at the top of the fixing frame 9. The adjusting screw 10 is threadedly connected to the fixing frame 9 through the threaded hole, which helps the adjusting screw 10 to move actively. The bottom of the adjusting screw 10 is rotatably connected to a lower pressing plate 11. The buffer pad 6 and the lower pressing plate 11 are in a semicircular shape. The buffer pad 6 and the lower pressing plate 11 are respectively in contact with the pipe body 7, which is convenient for using the lower pressing plate 11 and the buffer pad 6 to stably clamp and fix the pipe body 7.

[0025] Among them, a reset spring 12 is fixedly installed on the inner top wall of the fixing frame 9. The bottom of the reset spring 12 is fixedly installed with a limiting rod 13 fixedly connected to the lower pressing plate 11. A limiting groove is formed inside the upper clamping plate 3, and the limiting rod 13 is slidably connected to the upper clamping plate 3 through the limiting groove, which helps the limiting rod 13 to slide and move.

[0026] It should be noted that for the expansion sleeve device for clamping the plastic pipe plug, through the provided adjustment and fastening mechanism, by rotating the upper clamping plate 3, the upper clamping plate 3 is brought into fit and butt joint with the lower clamping plate 2, so that the fixing plates 4 on one side of the lower clamping plate 2 and the upper clamping plate 3 are butt-jointed, and the lower pressing plate 11 presses on the top of the pipe body 7. By using the adjusting screw rod 10 to drive the lower pressing plate 11 to move downward, at the same time, the reset spring 12 resets and pushes the lower pressing plate 11 to fix the pipe body 7, which is convenient for applying a force to the connection part of the two pipe bodies 7 and helps with fastening. Under the threaded connection of the adjusting screw rod 10, the reset spring 12 can be prevented from shaking, greatly improving the stability of clamping and fixing. The pipe body 7 can be quickly disassembled through the action of the adjusting screw rod 10 and the fixing bolt 5.

[0027] The working principle of the above embodiment is as follows:

[0028] For the expansion sleeve device for clamping the plastic pipe plug, when in use, first, the connection parts of the two pipe bodies 7 can be butted and placed on the top of the lower clamping plate 2. Then, the upper clamping plate 3 can be rotated so that the upper clamping plate 3 is brought into fit and butt joint with the lower clamping plate 2, so that the fixing plates 4 on one side of the lower clamping plate 2 and the upper clamping plate 3 are butt-jointed, and the lower pressing plate 11 presses on the top of the pipe body 7. The lower pressing plate 11 is stressed to drive the limiting rod 13 to move slightly, and the limiting rod 13 moves to compress the reset spring 12, so that the reset spring 12 is always in a reset state and applies a downward pressure, which is convenient for applying a force to the connection part of the two pipe bodies 7 and helps with fastening. Then, the fixing bolt 5 can be screwed into and fixed inside the two fixing plates 4 to limit and fix the lower clamping plate 2 and the upper clamping plate 3, and thus limit and fix the two pipe bodies 7;

[0029] After the lower clamping plate 2 and the upper clamping plate 3 are fixed, the adjusting screw rod 10 can also be rotated. The adjusting screw rod 10 moves downward inside the fixing frame 9 and drives the lower pressing plate 11 to move downward. At the same time, the reset spring 12 resets and pushes the lower pressing plate 11 to fix the pipe body 7. Under the threaded connection of the adjusting screw rod 10, the reset spring 12 can be prevented from shaking, greatly improving the stability of clamping and fixing. Under the action of the adjusting screw rod 10 and the fixing bolt 5, the pipe body 7 can be quickly disassembled, greatly improving the flexibility and practicality of the device.
