[0077] Reference Figure 6The lower inner wall of the operating hole 434 is fixedly connected to the limiting column 851. The operating spring 85 is arranged in the fixing hole 437 and sleeved outside the limiting column 851. The operating spring 85 is in a compressed state. One end of the operating spring 85 abuts against the lower inner wall of the fixing hole 437, and the other end of the operating spring 85 abuts against the third operating rod 84.

[0078] Reference Figure 6 and Figure 7 When the upper end surface of the first operating rod 82 abuts against the upper inner wall of the operating hole 434 , the second operating rod 83 extends into the operating groove 431 .

[0079] Reference Figure 4 and Figure 7 The locking hook 81 is fixedly connected to the inner wall of the operating cavity 433 close to the receiving groove 21. The locking hook 81 is made of a metal magnetic material and has elasticity. In other embodiments, the locking hook 81 is fixedly connected to the inner wall of the operating cavity 433 away from the receiving groove 21.

[0080] Reference Figure 5 and Figure 7 The hook portion of the locking hook 81 can pass through the insertion hole 821 on the first operating rod 82 and be inserted into the operating slot 431. The end surface of the operating block 44 facing the operating slot 431 is provided with a slot 442, and the slot 442 can be inserted into the hook portion of the locking hook 81. When the hook portion of the locking hook 81 abuts against the first operating rod 82, the locking hook 81 is in a deformed state.

[0081] Reference Figure 5 and Figure 7 When the upper end surface of the second operating rod 83 is coplanar with the bottom wall of the operating slot 431, the insertion hole 821 is aligned with the hook portion of the locking hook 81, and the hook portion of the locking hook 81 can pass through the insertion hole 821. When the upper end surface of the second operating rod 83 is higher than the bottom wall of the operating slot 431, the insertion hole 821 and the hook portion of the locking hook 81 are staggered, and the hook portion of the locking hook 81 can only contact the surface of the first operating rod 82, so that the first operating rod 82 limits the locking hook 81.

[0082] Reference Figure 6 and Figure 7 The unlocking member 86 is used to drive the hook portion of the locking hook 81 to disengage from the operating slot 431. Two unlocking members 86 are provided, and each unlocking member 86 can drive one locking hook 81 to move. The unlocking member 86 includes an unlocking rod 861 and a magnet 862.

[0083] Reference Figure 6 and Figure 7The unlocking rod 861 is slidably disposed on the upper inner wall of the operating cavity 433, and a dovetail block is fixedly connected to the upper end surface of the unlocking rod 861. A dovetail groove is provided on the upper inner wall of the operating cavity 433, and the dovetail block is slidably disposed in the dovetail groove. The magnet 862 is horizontally rotatably connected to the end surface of the unlocking rod 861 facing the operating hole 434. The magnet 862 and the locking hook 81 can be magnetically matched.

[0084] Reference Figure 6 and Figure 7 A driving member 87 capable of driving the unlocking rod 861 to move is provided on the operating seat 43. The driving member 87 includes a round rod 871, a rotating rod 872, a sliding rod 873 and a stopper 874.

[0085] Reference Figure 6 and Figure 7 The upper end surface of the operating seat 43 is provided with a round hole 438, and the round hole 438 is connected to the operating chamber 433. The round rod 871 is rotatably connected in the round hole 438. The round rod 871 is located between the two locking hooks 81, and the round rod 871 is located between the two unlocking members 86.

[0086] Reference Figure 7 The rotating rod 872 is sleeved on the outside of the round rod 871, and the rotating rod 872 is located below the unlocking rod 861. The upper end surface of the rotating rod 872 is provided with two sliding holes 8731, and the round rod 871 is located between the two sliding holes 8731. The sliding hole 8731 is in the shape of a long strip hole, and the length direction of the sliding hole 8731 is consistent with the length direction of the rotating rod 872.

[0087] Reference Figure 7 There are two slide bars 873, and each of the two slide bars 873 is slidably disposed in a slide hole 8731. The upper end surface of the slide bar 873 is fixedly connected to the lower end surface of the unlocking rod 861.

[0088] Reference Figure 7 There are two stoppers 874, and both stoppers 874 are fixedly connected to the upper inner wall of the operating chamber 433. The round rod 871 is located between the two stoppers 874. The stoppers 874 are located on the moving path of the locking hook 81 deforming toward the round rod 871.

[0089] The implementation principle of Example 2 is as follows: when replacing the operating block 44, firstly, the round rod 871 is driven to rotate, and the round rod 871 drives the rotating rod 872 to rotate synchronously, and the rotating rod 872 drives the unlocking rod 861 and the magnet 862 to move toward the locking hook 81 through the sliding rod 873, so that the magnet 862 and the locking hook 81 are magnetically matched. Secondly, the round rod 871 is driven to rotate in the opposite direction, so that the unlocking rod 861 and the magnet 862 move in the opposite direction, so that the magnet 862 drives the locking hook 81 to move, so that the locking hook 81 is deformed, and the locking hook 81 is separated from the operating slot 431 and the insertion hole 821. Next, the original operation block 44 in the operation slot 431 is removed. At this time, the second operation rod 83 is no longer limited by the operation block 44. The operation spring 85 drives the second operation rod 83 to extend out of the operation slot 431 and drives the first operation rod 82 to move upward, so that the insertion hole 821 and the hook portion of the locking hook 81 are offset. The hook portion of the locking hook 81 is limited by the first operation rod 82 and cannot be inserted into the operation slot 431. Finally, a new operation block 44 is placed in the operation slot 431. The operation block 44 drives the second operation rod 83 to descend, and the second operation rod 83 drives the first operation rod 82 to descend, so that the insertion hole 821 is aligned with the hook portion of the locking hook 81. Due to the reset of the locking hook 81, the hook portion of the locking hook 81 passes through the insertion hole 821 and is inserted into the slot 442 of the operation block 44, so that the new operation block 44 is locked with the locking hook 81.
