[0023] The positioning rod 30 is sleeved with the upper positioning member 31 on the outer side, and the lower end surface edge of the upper positioning member 31 is an upper positioning curved surface 32.

[0024] The upper positioning member 31 is provided with a positioning plate 40, the positioning rod 30 passes through the through hole B41 of the positioning plate 40, and the positioning rod 30 and the adjusting portion 51 are adjustably connected.

[0025] As Figure 1The adjustable connection between the positioning rod 30 and the adjusting part 51 is that a through hole C42 is arranged on the positioning plate 40, the adjusting part 51 is provided with external threads, the adjusting part 51 passes through the through hole C42, and the upper and lower sides of the positioning plate 40 are both provided with adjusting nuts A which are matched with the external threads of the adjusting part 51.

[0026] As Figure 1 In order to operate stably, the upper positioning curved surface 32 is parallel to the lower positioning curved surface 22.

[0027] As Figure 1 The positioning connecting area 23 is a screw hole, and the lower end of the connecting positioning rod 30 is provided with external threads matched with the screw hole.

[0028] As Figure 3 In order to be stable, the two sides of the plug plate 60 are provided with plug grooves 62 matched with the clamping parts 52, the middle part of the plug plate 60 is provided with a through hole D61, a bolt 63 is arranged in the through hole D61, the diameter of a nut B65 of the bolt 63 is greater than that of the through hole D61, the nut B65 is always kept above the plug plate 60, and the lower end of the bolt 63 is provided with an adjusting nut B64 matched therewith.

[0029] As Figure 2 In order to facilitate rotation, the radial direction of the positioning part 31 is fixed with a handle 35.

[0030] The working principle is as follows:

[0031] As Figures 4-5 In use, the following steps are included:

[0032] S1, the connecting rod 91 is rotated, and the distance between the mounting plate 10 and the machine 90 is adjusted. This is prior art.

[0033] S2, the positioning rod 30 is rotated, and the distance between the nut A of the positioning rod 30 and the mounting plate 10 is adjusted.

[0034] S3, the adjusting nut A is rotated, the plug rod 50 is adjusted to slide up and down, and the distance between the clamping part 52 and the mounting plate 10 is adjusted.

[0035] S4, the adjusting nut B64 is rotated, and the distance between the adjusting nut B64 and the nut B65 is adjusted.

[0036] S5, as Figure 4 The upper positioning part 31 is rotated, the lower position work station (the lower position of the upper positioning curved surface 32) of the upper positioning part 31 is contacted with the lower position work station (the lower position of the lower positioning curved surface 22) of the lower positioning part 20, the mounting plate 10 falls on the upper positioning part 31 by gravity, and the plug rod 50 is located at the lower position.

[0037] S6, put the plug plate 60 in the installation area 98 of the last 99, insert the engaging part 52 in the slot 62, and hang the last 99 on the positioning rod 30.

[0038] S7, as Figure 5 , rotate the upper positioning member 31, so that the high position of the upper positioning member 31 (the higher position of the upper positioning curved surface 32) is in contact with the high position of the lower positioning member 20 (the higher position of the lower positioning curved surface 22), the position of the upper positioning member 31 is forced to be raised, and the positioning plate 40 is also raised, and at the same time, the positioning plate 40 is clamped between the positioning plate 40 and the nut A of the positioning rod 30, and the positioning plate 40 is accurately positioned.

[0039] At the same time, as Figure 5 , when the positioning plate 40 is raised, the last 99 is moved upward by the plug plate 60, and when the nut B 65 contacts the upper surface of the installation area 98 of the last 99, the last 99 cannot continue to rise, and at the same time, the positioning plate 40 is accurately positioned, the plug plate 60 cannot continue to move downward, and the last 99 is clamped between the plug plate 60 and the installation plate 10 with the assistance of the nut B 65.

[0040] In this way, the last 99 is fixed on the machine 90.

[0041] If it is necessary to remove the last 99 from the machine 90, only need to rotate the upper positioning member 31, so that the low position of the upper positioning member 31 (the lower position of the upper positioning curved surface 32) is in contact with the low position of the lower positioning member 20 (the lower position of the lower positioning curved surface 22), the installation plate 10 falls on the upper positioning member 31 by gravity, and the plug rod 50 is located at the lower position, at this time, the engaging part 52 and the slot 62 become loose, facilitating the removal of the last 99 from the machine 90.

[0042] The features of the present application are:

[0043] S1, installation and disassembly of the last 99, only need to rotate the upper positioning member 31, very convenient.

[0044] S2, when installing the last, the last 99 is clamped between the plug plate 60 and the installation plate 10, which is very stable.

[0045] Other contents refer to the prior art.

[0046] The above is only the preferred embodiment of the present application, and it should be pointed out that for those skilled in the art, without departing from the overall concept of the present application, a number of changes and improvements can be made, which should also be regarded as the protection range of the present application.
