[0090] The design utilizes a connecting rod mechanism to realize the conversion of swing into linear motion. The design can refer to the existing swing locking clamp design and will not be described in detail.

[0091] The structure of the first pressure head 22 in the present application can be designed and adapted according to the actual end structure of the first workpiece 5. In order to facilitate disassembly, it is designed as a detachable connection, and there is no specific limitation.
