[0033] Example 1

[0034] Please see Figures 1-5 The technical solution provided in this embodiment is as follows:

[0035] The attachment locking mechanism consists of a base plate 1, a limiting block 2, a slide rail mechanism, an attachment base 14, a top block 3, and a transmission linkage mechanism. There are three limiting blocks 2, and all three limiting blocks 2 can be detachably connected to the top of the base plate 1. There are three top blocks 3, and each top block 3 is located on each set of slide rail mechanisms. The attachment base 14 is located on the base plate 1 and the three limiting blocks 2.

[0036] In a specific embodiment of this utility model, the attachment base 14 is placed on three limiting blocks 2, and the attachment base 14 is movably inserted into the base plate 1. The base plate 1 is used to install the attachment locking mechanism. Each top block 3 is slidably connected to each top block groove 11, and each top block 3 is restricted by two pressure blocks 4, so that the top block 3 can only slide within the top block groove 11. By moving the top block 3 and cooperating with the limiting blocks 2, the locking of the core-retrieving attachment and the attachment base fixing assembly can be achieved. The limiting blocks 2 are used to restrict the position of the attachment base 14. Each top block 3 is provided with a circular groove, through which the top block 3 can press against the bottom of the attachment base 14 (e.g., Figure 5 (as shown), thereby locking the attachment base 14.

[0037] Specifically, there are three sets of slide rail mechanisms, all of which are located on the top of the base plate 1. Each set of slide rail mechanisms includes a pressure block 4 and a top block groove 11. The top block groove 11 is located on the top of the base plate 1. There are two pressure blocks 4, which are detachably connected to the top of the base plate 1 by screws.

The connecting rod 5 is rotatably connected to the top block 3, so that the moving connecting rod 5 drives the top block 3 to move.

[0043] Specifically, the surface of the connecting plate 8 is fixedly connected to two reinforcing plates 9, which are arranged symmetrically.

[0044] In a specific embodiment of this utility model, the strength of the connecting plate 8 can be improved by setting two reinforcing plates 9.

[0045] Specifically, the top of the base plate 1 has three arc-shaped holes 12, which are evenly distributed.
