The plurality of toggle clamps 1 are transitionable with the linkage 7 linearly reciprocating in the first direction between a clamping state (as shown in fig. 3A-3B) in which the toggle clamps 1 clamp an object and a releasing state (as shown in fig. 4A-4B) in which the toggle clamps 1 release the object. The coupling assembling includes: a rotary drive member 6 engaged with the link member 7, the rotary drive member 6 converting linear motion of the link member 7 into rotary motion, a rotation axis of the rotary drive member 6 extending in a second direction perpendicular to the first direction; and a linear transmission member 5 engaged with the rotary transmission member 6, wherein the linear transmission member 5 converts the rotary motion of the rotary transmission member 6 into a linear motion along a second direction, and the linear transmission member 5 is connected with the elbow clamp 1 to drive the elbow clamp 1 to convert between a clamping state and a releasing state.

The second direction is perpendicular to the surface of the object to be clamped. In the embodiment shown in the drawings, the first direction is the z-axis direction and the second direction is the y-axis direction. The plurality of elbow clamps 1 are arranged side by side in the first direction, which means that the plurality of elbow clamps 1 are arranged approximately aligned with each other in the first direction, so that the plurality of elbow clamps 1 can clamp the object at the same time. In the embodiment shown in the figures, the object being clamped is a glass substrate 200. In the embodiment shown in the figures, each linkage 7 is intended to connect five toggle clamps 1 to enable simultaneous actuation (for example, simultaneous clamping or simultaneous release, simultaneous opening or simultaneous closing) of the five toggle clamps 1. It should be understood that the number of toggle clamps 1 used by the linkage 7 for linkage is not limited thereto, and may be changed according to actual needs. It should be noted that: in the present application, the terms "clamping" and "closing" of the elbow clamp are used interchangeably to refer to the state that the elbow clamp clamps an object, and the terms "releasing" and "opening" of the elbow clamp are used interchangeably to refer to the state that the elbow clamp releases the object.

In the embodiment shown in the drawings, the elbow clamp 1 is a horizontal elbow clamp. Horizontal toggle clamps are commercially available mature products, the structure of which is well known in the art and therefore not described in much detail in this application, but are simply illustrated for the sake of clarity. The toggle clamp 1 generally comprises a base, a clamping body hinged on the base and an actuating handle connected with the clamping body. The clamping body is provided with a clamping part used for abutting against an object to realize the purpose of clamping. When clamping the object, the actuating handle can be actuated to rotate (for example, rotate anticlockwise) to drive the clamping body to rotate (for example, rotate clockwise) so that the clamping part of the clamping body is close to and abutted against the object, thereby achieving the purpose of clamping the object; when the object is loosened, the actuating handle can be actuated to rotate (e.g., rotate clockwise) to rotate (e.g., rotate counterclockwise) the clamping body to move the clamping portion of the clamping body away from the object, thereby achieving the purpose of loosening the object.

In the embodiment shown in the drawings, the connecting assembly further comprises a hinge plate 3, one end of the hinge plate 3 is hinged to the linear transmission 5 (for example, by a pin 2), and the other opposite end is hinged to the toggle clamp 1 (specifically, the actuating handle of the toggle clamp 1) (for example, by a pin 2), so that the hinge plate 3 is pivoted by the linear motion of the linear transmission 5 in the second direction, and the actuating handle of the toggle clamp 1 is pivoted by the hinge plate 3, thereby causing the state of the toggle clamp 1 to change.

In the embodiment shown in the figures, the linkage 7 is a rack, the rotary drive 6 is a gear wheel engaging with the rack, and the linear drive 5 is a lead screw engaging with the gear wheel. The external teeth of the gear are meshed with the rack to convert the linear motion of the rack into rotary motion; the inner bore of the gear is provided with an internal helical raceway (equivalent to a nut) and the lead screw is engaged with the internal helical raceway of the inner bore of the gear to convert the rotational motion of the gear into linear motion of the lead screw. The lead screw is fixedly connected (e.g. welded) to a lead screw mount 5, which lead screw mount 5 is articulated to the hinge plate 3, thereby converting the linear movement of the lead screw into a pivotal movement of the hinge plate 3. The gear is mounted in a gear mount 8, and a gear mount gland 9 is mounted on the gear mount 8 to press against the gear to restrict axial movement (i.e., movement in the y-axis direction) of the gear. The rack limiting plate 10 is installed on the gear installation seat 8 and used for enabling the rack to be perfectly meshed with the gear and preventing the rack from shaking. In one embodiment, the rack may be provided with teeth engaging with the gear wheel throughout its extension. In the embodiment shown in the drawings, the rack is provided with teeth meshed with the gear only at the part meshed with the gear in the extending direction, and the range of the teeth is within the movement allowance range of the gear. When the rack moves upwards or downwards along the z-axis, the gear rotates along with the rack, and the gear does not move axially due to the action of the gear mounting seat 8 and the gear mounting seat gland 9. Because the inner hole of the gear 6 is provided with the inner spiral raceway, the screw rod only does axial motion, and the screw rod and the elbow clamp 1 complete opening and closing actions through the action of the connecting rod.

In another embodiment, the linkage 7 may be a worm, the rotary drive 6 may be a worm gear engaged with the worm, and the linear drive 5 is a lead screw engaged with the worm gear. In this case, the external teeth of the worm wheel are engaged with the worm to convert the linear motion of the worm into the rotational motion of the worm wheel; the inner bore of the worm gear is provided with an internal helical raceway (equivalent to a nut) and the lead screw is engaged with the internal helical raceway of the inner bore of the worm gear to convert the rotational motion of the worm gear into linear motion of the lead screw. In other embodiments, the linkage, the rotary drive, the linear drive may be provided with additional mechanisms known in the art that may effect a transformation of a linear motion to a rotary motion and a transformation of a rotary motion to another linear motion.

In some cases, a handle 13 may be provided on linkage 7 to facilitate manual actuation of handle 13 to manually drive movement of linkage 7. The handle 13 may be screwed to the link 7 or may be welded to the link 7. In other cases, a driving mechanism, such as a motor or a cylinder, may be connected to the linkage to drive the linkage 7 to move through the driving mechanism.

In some cases, the toggle clamp switch apparatus may further include a limiting structure to limit a moving range of the link 7, and the limiting structure may include a fixedly disposed limiting post 11 and a long slot hole disposed on the link 7, through which the limiting post may pass. The spacing post 11 can be fixed (e.g., threaded connection, or welded) on the spacing post mount 12, the spacing post mount 12 can be fixed to a fixed structure, and the spacing post 11 passes through a long slot hole on the rack 7, so that the rack can be moved to a spacing effect.
