[0045] The guide component 5 is arranged to penetrate the first hole, the elastic component 4, and the second hole;

[0046] The locking assembly 6 is hinged to the mounting base 1 at a first hinge point;

[0047] In the first state, the sliding component 3 compresses the elastic component 4 and slides along the guide component 5 toward the protrusion 2, driving the locking component 6 to rotate in the first direction around the first hinge point to unlock; in the second state, the elastic component 4 restores the elastic deformation, driving the sliding component 2 to slide in the direction away from the protrusion 2, driving the locking component 6 to rotate in the second direction around the first hinge point to lock.

[0048] In this embodiment, the locking component 6 is placed in a locked or unlocked state by changing the deformation state of the elastic component 4, and can be quickly locked or unlocked, thereby effectively improving work efficiency. When used in conjunction with other automatic clamping equipment, it effectively reduces the risk of personal injury in certain scenarios.

[0049] refer to Figure 1 In the embodiment shown, the mounting seat 1 preferably includes: a connecting member 11; an articulated seat 12; a mounting base 13; the number of articulated seats is consistent with the locking assembly, and is arranged around the mounting base, the connecting member 11 is hinged to the articulated seat 12 at one end, and is hinged to the locking assembly 6 at the other end; more preferably, a linkage rod 14 is arranged between two adjacent articulated seats, for example, Figure 1As shown, the sliding assembly 3 has two sets of locking assemblies on the left and right, and the two hinged supports are connected by a linkage rod 14, so that the two locking assemblies can be linked.
