In this embodiment, the slider bar 100 may be used to fix a flexible buckle cap with an electronic tag on an adapter, and a perforation is reserved on the adapter of a specific existing device, the slider bar 100 may be passed through the perforation, and the end of the slider bar 100 is limited on one side of the perforation by the expansion sleeve 200.

Specifically, in the present embodiment, the expansion sleeve 200 is made of a soft plastic material, which has certain flexibility and toughness, and further, the expansion sleeve 200 is a tapered sleeve, the outer diameter of the end a is smaller than the outer diameter of the end b, and it should be noted that the outer diameter of the end a is smaller than the outer diameter of the through hole, the outer diameter of the end b is larger than the outer diameter of the through hole, and the inner diameter of the end b is smaller than the inner diameter of the position c.

Therefore, in the process that the sliding rod 100 with the expansion sleeve 200 is inserted into the through hole, namely when the sliding rod 100 moves to the left side in figure 1, the end a passes through the through hole, the end b does not easily pass through the through hole, so that the expansion sleeve 200 and the sliding rod 100 move relatively, and the end b is extruded to pass through the through hole at the extrusion position b at the extrusion position c; at this time, the sliding rod 100 is pulled back, that is, the sliding rod 100 is pulled to the right side of fig. 1, because the dimension of the end b is larger than that of the through hole, the end b is abutted against the adapter, the end a of the expansion sleeve 200 is pushed and sleeved on the sliding rod 100 at the left side part of the annular groove 101, the dimension of the expansion sleeve 200 is increased, and the sliding rod 100 is more difficult to pass through the through hole, so that one end of the sliding rod 100 is fixed on the adapter.

The operation in the process is only one insertion, one extrusion and one pulling, and is convenient and quick.

The slider bar 100 is a nylon material.

Example 2

Referring to fig. 2, the present embodiment is different from the previous embodiment in that the present embodiment provides a case where one end of the expansion sleeve 200 is provided with the separation preventing hook 203, and it should be noted that, in this case, the expansion sleeve 200 may be a cylindrical soft sleeve with a uniform size, which is more convenient to pass through the perforation, and when the expansion sleeve is pulled back after passing through, the separation preventing hook 203 is bent and deformed to be pushed at the perforation, so that the expansion sleeve 200 is pushed onto the expansion column 103.

Example 3

Referring to fig. 3, the difference between this embodiment and the previous embodiment is that the expansion sleeve 200 of this embodiment is made of hard material, and the complete circular size is difficult to deform, so that the expansion sleeve 200 is provided with a radial groove 201; the sliding rod 100 is provided with an anti-receding column 102 and an expanding column 103, and the anti-receding column 102 and the expanding column 103 are respectively arranged on two sides of the ring groove 101.

It should be noted that the radial grooves 201 are through grooves that penetrate through both ends of the expansion sleeve 200.

The inner diameter of the expansion sleeve 200 is provided with a chamfer surface 202 towards one end of the expansion column 103, one side of the expansion column 103, which faces the ring groove 101, is provided with a guide cone 105, and the chamfer surface 202 and the guide cone 105 are arranged in opposite directions, so that the expansion sleeve 200 can be conveniently sleeved on the expansion column 103 in the moving process.

The expansion sleeve 200 is provided with a separation preventing hook 203 at one end near the separation preventing column 102, and it should be noted that the separation preventing hooks 203 are arranged in pairs, and the size of the outer diameter of the separation preventing hook 203 far from the expansion sleeve 200 is increased.

The end part of the expansion column 103 is provided with a head 104; the outermost side of the anti-withdrawal column 102 is larger than the inner diameter of the expansion sleeve 200; the outer diameter of the expansion column 103 is larger than that of the ring groove 101, and the size of the end head 104 is larger than that of the expansion column 103; it should be noted that the outer diameter dimension of the expansion column 103 is greater than the inner diameter dimension of the expansion shell 200.

The size of anti-retreat column 102 is larger than the size of expansion shell 200, limiting the inability of expansion shell 200 to nest over anti-retreat column 102.

Further, in the process of inserting the sliding rod 100 with the expansion sleeve 200 into the through hole, the anti-withdrawal column 102 extrudes the expansion sleeve 200 to penetrate through the through hole, the anti-release hook 203 is pressed towards the middle to penetrate through the through hole and then is opened towards two sides, at the moment, the sliding rod 100 is pulled back, the anti-release hook 203 is extruded by the adapter, the expansion sleeve 200 is extruded and sleeved on the expansion column 103, the opening of the radial groove 201 is enlarged, the outer diameter size of the expansion sleeve 200 is enlarged, and the expansion sleeve 200 cannot penetrate through the through hole.

The end 104 has a limiting effect on the expansion sleeve 200.

Example 4

Referring to fig. 2 and 4, the present embodiment is different from the previous embodiment in that the inner diameter of the expansion sleeve 200 is a tapered hole 204; the expansion column 103 is a tapered column.

It should be noted that the larger size end of the expansion column 103 is adjacent to the head 104.

The end with the large size of the tapered hole 204 faces the side where the expansion column 103 is located, the anti-drop hook 203 is arranged at the end with the small size of the tapered hole 204, it should be noted that the overall size of the expansion column 103 is larger than the size of the tapered hole 204, and when the expansion sleeve 200 is sleeved on the expansion column 103, the expansion column 103 expands the size of the expansion sleeve 200.

The tapered bore 204 and the tapered post are profiled to facilitate the expansion shell 200 being fitted over the expansion post 103.
