Drawings

Fig. 1 shows a schematic front view structure diagram of an embodiment of the present invention.

In the figure: 1. the novel clamp comprises a first hanging ring, a second hanging ring, a first rod, a second rod, a cross rod, a clamping block, a first chain, a first hinge point, a second hinge point, a third hinge point, a second chain, a first section, a second section, a fifth hinge point, a hinge.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model relates to a hanging tong, including rings 1, rings 2 No. two, a pair of pole 3, a pair of pole 4 No. two, horizontal pole 5 and a pair of clamp splice 6, a link connection a pair of chain 7 No. one, a pole is equipped with a pin joint 8, No. two pin joints 9 and No. three pin joints 10, and is a pair of a pin joint of a pair of pole is connected respectively to a chain, the horizontal pole is articulated with No. two pin joints of a pole, No. three pin joints of a pole are articulated with the clamp splice, horizontal pole and clamp splice are connected respectively to the both ends of No. two poles, No. two chains 11 are connected to the mid point of horizontal pole, No. two rings are connected to No. two chains. The first rod, the cross rod, the second rod and the clamping block form a four-bar mechanism.

According to the technical scheme, preferably, the first rod comprises a first section 12 and a second section 13 which are integrally formed, an included angle is formed between the first section and the second section, a first hinged point is arranged at the end of the first section, a third hinged point is arranged at the end of the second section, and a second hinged point is arranged at the joint of the first section and the second section and the cause.

According to the technical scheme, preferably, a pair of fifth hinge points 14 are arranged at two ends of the cross rod, a pair of fourth hinge points 15 are arranged between the middle point of the cross rod and the fifth hinge points respectively, the first rod and the cross rod are hinged through the second hinge point and the fourth hinge point, and the second rod and the cross rod are hinged at the fifth hinge point.

According to the technical scheme, preferably, the clamping block is provided with an inner side hinge point 16 and an outer side hinge point 17, the first rod is hinged with the clamping block through a third hinge point and the inner side hinge point, and the second rod is hinged with the clamping block through the outer side hinge point.
