One end of the outer clamping member is fixedly disposed on the connecting member, and the outer clamping member is used to press against the outer surface of the ring-shaped object 9 to be transported. The first end of the operating member is fixedly connected to the connecting member, and the second end of the operating member is used for operation by the operator.
[0026] The clamp for transporting ring-shaped objects provided in this embodiment connects the inner clamping member, the outer clamping member, and the operating member into one unit through a connector. The inner clamping member presses against the inner surface of the ring-shaped object 9 to be transported, and the outer clamping member presses against the outer surface of the ring-shaped object 9 to be transported, thereby clamping and fixing the ring-shaped object 9 to be transported. The operator operates the second end of the operating member to transport and transfer the ring-shaped object 9 to be transported. This can effectively improve the transport efficiency, prevent safety accidents, and avoid unnecessary losses. The clamp for transporting ring-shaped objects provided in this embodiment is particularly suitable for transporting large ring-shaped molds of manual presses, and is also suitable for transporting other ring-shaped objects. Among them, other ring-shaped objects are not limited to rings, nor are they limited to molds.
[0027] As a preferred embodiment of this invention, the connector is placed above the annular object 9 to be transported, so as to facilitate lifting the annular object 9. As an optional embodiment of this invention, when the annular object 9 to be transported is partially suspended and placed on the support, and there are conditions that allow it to be lifted from bottom to top, the connector can also be placed below the annular object 9 to be transported, so as to facilitate lifting the annular object 9 from bottom to top.
[0028] As a preferred embodiment of this invention, one end of the outer clamping member can be detachably fixed to the connecting member, and the distance between the outer clamping member and the inner clamping member can be adjusted and locked to accommodate different wall thicknesses of different annular objects 9 to be transported.
[0029] In a preferred embodiment of this invention, the inner clamping member includes two clamping rods 1, the connecting member includes two connecting rods 2, the operating member includes two operating rods, and the outer clamping member includes a clamping plate 3. The clamping rods 1, connecting rods 2, and operating rods correspond one-to-one. The clamping rods 1 are used to press against the inner surface of the annular object 9 to be transported. One end of the clamping rod 1 is fixedly connected to one end of the connecting rod 2, and the other end of the connecting rod 2 is fixedly connected to the first end of the operating rod. The second end of the operating rod is used for operation by the operator. The clamping plate 3 is used to press against the outer surface of the annular object 9 to be transported. The clamping plate 3 is connected to the two connecting rods 2. The clamping plate 3 can move along the two connecting rods 2 towards or away from the two clamping rods 1. The clamping plate 3 and the two connecting rods 2 can be locked. The structure is simple, easy to manufacture and use, and is especially suitable for transporting large annular molds of manual presses.
[0030] As a preferred embodiment of this invention, the clamping plate 3 has two connecting holes, which correspond one-to-one with the connecting rod 2. The connecting rod 2 passes through the connecting holes, which is simple in structure and easy to manufacture and use.
[0031] As a preferred embodiment of this invention, the outer clamping member also includes two locking screws 4, which correspond one-to-one with the connecting holes. The locking screws 4 are threadedly connected to the clamping plate 3, and one end of the locking screw 4 can extend into the connecting hole and be locked onto the connecting rod 2, which is convenient for manufacturing and use.

The elastic sleeve 5 and the elastic pad 6 are preferably, but not limited to, made of rubber material, so as to use the elastic properties of rubber material to prevent collision and scratches on the ring-shaped object 9 to be transported during the transport process.
[0033] In a preferred embodiment of this invention, the clamping plate 3 is parallel to the two clamping rods 1 and perpendicular to the two connecting rods 2. The operating rod has an inclined section 7 and a horizontal section 8. The first end of the inclined section 7 is fixedly connected to the end of the connecting rod 2 away from the clamping rod 1. The second end of the inclined section 7 extends upward at an incline relative to the connecting rod 2. The second end of the inclined section 7 is fixedly connected to one end of the horizontal section 8. The horizontal section 8 is used for operation by the operator and can effectively prevent the operator from bending over too much when moving the ring-shaped object 9 because the ring-shaped object 9 is relatively short, making it easier for the operator to exert force.
[0034] In a preferred embodiment of this invention, the clamping rod 1, the connecting rod 2, and the operating rod are all made of stainless steel tubing with a diameter of 20mm; the clamping rod 1 is 90mm long, the elastic sleeve 5 is 80mm long, the tilt angle of the inclined section 7 is 30°, the diameter of the connecting hole is 20.2mm, and the thickness of the elastic pad 6 is 5mm.
