A through hole 43 is provided on the inner wall of the connecting groove 41. The through hole 43 is as shown in FIG. Figure 4 As shown in the symmetrical arrangement, between the two groups of through holes 43 (the inner wall of the connecting groove 41 is provided with a through hole 42 connected to the outside), a docking member 5 (such as Figure 2 As shown), a locking member 6 is slidably connected in the through hole 42, and the locking member 6 and the docking member 5 are matched in the connecting member 2 (as shown in FIG. Figure 9 shown).

[0026] Connector 2 (such as Figure 5 、 9As shown in the figure: The connecting piece 2 is provided with a docking cavity (21). On the inner wall of the docking cavity (21), there is a jack 22 for the locking piece 6 to slide. The opposite surfaces of the docking piece 5 are slidably connected in the docking cavity (21). The locking piece 6 is inserted into the docking cavity 21 from the jack 22 and is connected to the docking piece 5 to complete the connection.

[0027] The docking piece 5 (such as Figure 5 , 6 , 7 shown in the figure): The docking rod 51 is slidably connected in the through hole 43. And on the opposite surfaces of the docking rod 51, there are positioning blocks 55. On the opposite surfaces of the docking seat 52, there are sliding grooves 56. The cross-section of the sliding groove 56 is T-shaped. And the bottom of the sliding groove 56 is as Figure 7 shown in the figure. The positioning block 55 is a T-shaped block. After being inserted into the sliding groove 56, the docking seat 52 moves downward to complete the installation of the docking rod 51 and the docking seat 52. On the opposite surfaces of the docking seat 52, there are docking grooves 53 with a semi-circular cross-section. On the inner top surface of the docking groove 53, there are T-shaped limiting blocks 54. After the two groups of docking seats 52 are docked, the two groups of limiting blocks 54 are docked synchronously. The locking piece 6 is inserted from the through hole 42, passes through the jack 22, enters the docking groove 53, and rotates to complete the installation of the side milling head body 3.

[0028] The locking piece 6 (such as Figure 8 shown in the figure): The end face of the locking rod 61 is provided with a locking groove 62. And on the end face of the locking groove 62, there is an inwardly extending inlet groove 63. The inlet groove 63 is adapted to the limiting block 54. For the assembly between the mounting seat 1 and the mounting base plate 4, at the root of the inlet groove 63, there is an L-shaped positioning groove 64. The positioning groove 64 and the inlet groove 63 cooperate to form a fishhook shape.

The docking seat 52 moves downward. After completion of the assembly, align the connection groove 41 on the mounting base plate 4 with the connecting part 2 at the bottom of the mounting seat 1. After completion of the docking, push the two docking rods 51 towards the middle to insert the docking seat 52 into the docking cavity 21 of the connecting part 2. After completion, align the docking grooves 53 and the limiting blocks 54 of the two docking seats 52. After the docking groove 53, the jack 22, and the through hole 42 are concentric, insert the locking part 6 into the above-mentioned through hole 42 and finally into the docking groove 53. During this process, the limiting block 54 enters the locking groove 62 and the inlet groove 63 and slides therein (push the locking rod 61 inward), and presses the top plate 8 and compresses the spring 7. Then rotate the locking rod 61 to make the limiting block 54 enter the positioning groove 64 from the inlet groove 63. Then release the locking rod 61. Under the action of the spring 7, the locking rod 61 is pushed outwards by the top plate 8, and under the action of the positioning groove 64, the assembly of the mounting seat 1 and the side milling head body 3 is completed. Then rotate the nut 65 to complete the tightening operation.
