As described above, the supporting base plate 101 is used to mate with the target object, the supporting top plate 103 is used to support the middle supporting member 2, and the supporting tube 102 serves to support and raise the seat to meet the installation height requirements. Furthermore, the use of tubular components contributes to lightweight design. It should be noted that the structure of the lower supporting member 1 is not limited to this and can be designed according to actual needs.

[0038] Furthermore, preferably, along the vertical direction, the top support plate 103 is disposed above, the bottom support plate 101 is disposed below, and a plurality of support tubes 102 are disposed between the top support plate 103 and the bottom support plate 101.

As can be seen from the structure described above, the locking screw 41 is fixed on the support plate 21 of the middle support member 2. Therefore, the upper seat support member 3 can be fixed or released simply by turning the locking nut 42. The operation is simple and convenient.

[0042] Furthermore, preferably, the locking nut 42 is a wing nut, but of course, it is not limited to this.

[0043] It should be noted that the structure of the locking component 4 is not limited to the above. It can also adopt a combination structure of detachable bolts and nuts. That is to say, the bolts are not fixed to the middle support component 2, and the bolts are also detachable. The specific choice depends on the actual needs. In this embodiment, preferably, as follows: Figure 1 As shown, the middle support member 2 and the lower support member 1 are detachably connected by the first fastening member 7, such as screws or bolts, which is a detachable structure that is easy to install and disassemble.

[0045] Furthermore, preferably, the first preset direction a is the length direction of the support plate 21 of the middle support member 2. Of course, it is not limited to this, and can also be the width direction of the support plate 21 of the middle support member 2, depending on the actual needs.

[0046] In this embodiment, preferably, as follows: Figure 1 As shown, the lower support member 1 is detachably connected to the target object by a second fastening member such as a screw or bolt, which is a detachable structure that is easy to install and disassemble. Furthermore, preferably, the lower support member 1 is provided with a mounting through hole 31 for mounting the second fastening member.
