A schematic structural diagram of the first portion 11 is shown in fig. 4, the first portion 11 includes a first tube 111 and a first nut seat 112, as shown in fig. 5, one end of the first tube 111 is provided with the first nut seat 112, and an inner tube wall of the other end is provided with an inner thread section;
the second portion 12 is schematically shown in fig. 6, and a cross-sectional view taken along line a-2-a2 is shown in fig. 8, the second portion 12 includes a second tubular body 121, an externally threaded tube 122, a second nut holder 123 and a first bolt 124, and the externally threaded tube 122 is disposed at one end of the second tubular body 121 as shown in fig. 7; the second nut seat 123 is arranged in the external thread pipe 122, the first bolt 124 is arranged on the second nut seat 123 in a penetrating way, and the rod body of the first bolt 124 faces a direction far away from the pipe cavity of the second pipe body 121;
when the sleeve is configured to be used, the second tube 121 is inserted into the first tube 111, the first bolt 124 is inserted into the first nut seat 112, and the external threaded tube 122 is connected to the internal threaded section provided on the inner wall of the first tube 111 in a matching manner, so that both ends of the first portion 11 are fixedly connected to both ends of the second portion 12, thereby forming a sleeve 1 structure of an inner and outer double-layer tube, and enhancing the compression strength.
It can be understood that the sleeve 1 of the double-layer pipe body replaces the single-layer pipe body in the prior art, so that the firmness of the structure is enhanced, and the structure is ensured to be still firm and stable when being pressed.
The following further description of the sleeve structure of the embodiments of the present invention:
as for the first portion 11, the first portion 11 is an outer tube portion of the sleeve 1 of the embodiment of the present invention.
In order to ensure that the second pipe 121 can be inserted into the first pipe 111, it can be understood that the pipe diameter of the second pipe 121 is smaller than that of the first pipe 111, as shown in fig. 2.
By providing the first nut seat 112, when the second pipe body 121 is inserted into the first pipe body 111, the axial position of the second pipe body 121 can be limited and the second pipe body 121 can be fixed.
In order to facilitate the thread-fit connection between the external thread pipe 122 and the first pipe body 111, in terms of structural configuration, the diameter of the external thread pipe 122 is greater than the diameter of the second pipe body 121, as shown in fig. 7, which facilitates the thread connection between the external thread on the outer wall of the external thread pipe 122 and the internal thread section provided on the inner wall of the first pipe body 111.
As for the second portion 12, the first portion 11 is an inner pipe portion of the casing 1 of the embodiment of the present invention.
Since the external thread tube 122 only serves as a coupling, in the embodiment of the present invention, the length of the external thread tube 122 is much smaller than that of the second tube body 121, as shown in fig. 7.
By arranging the second nut seat 123 and the first bolt 124, and successively arranging the first bolt 124 on the second nut seat 123 and the first nut seat 112, one end of the first portion 11 can be connected with one end of the second portion 12.
When the second pipe 121 enters the first pipe 111, the second pipe 121 is rotated to make the first bolt 124 penetrate the first nut seat 112, and meanwhile, the external thread section on the outer wall of the external thread pipe 122 can be matched with the internal thread section arranged on the inner wall of the first pipe 111 to synchronously realize thread connection, so that the other end of the first portion 11 is connected with the other end of the second portion 12.

The third nut seat 125 and the second bolt 126 are provided to facilitate the connection of the socket 1 with the corresponding portion when being mounted on the multifunctional jack for an automobile.
As will be understood by those skilled in the art, since the tubular body is a circular tubular body, the nut seats correspondingly disposed at one end or both ends of the tubular body are all circular nut seats, that is, the first nut seat 112, the second nut seat 123 and the third nut seat 125 are all circular nut seats, and the outer diameter of the second nut seat 123 is greater than the outer diameter of the third nut seat 125, as shown in fig. 2.
Since the first portion 11 and the second portion 12 are detachably connected, when the casing 1 is not in use, the first portion 11 and the second portion 12 can be detached from each other, the second tube 121 is no longer inserted into the first tube 111, and the external threaded tube 122 is reversely fitted and connected with the internal threaded section provided on the inner wall of the first tube 111, so that the first portion 11 and the second portion 12 are connected to form a long tube with different diameters.
In terms of material selection, the casing 1 in the embodiment of the invention can be made of rigid materials, has high strength and good pressure resistance, and is convenient to obtain, manufacture and install.
