The lower surface of the cylindrical block 401 is connected with a radial base block 402, a strip-shaped limiting groove 4021 is arranged in the radial base block 402, a rotating rod 403 is connected in the strip-shaped limiting groove 4021, and the end face of one end of the rotating rod 403, which extends out of the radial base block 402, is connected with a second rocker 404. External threads 4031 are arranged at two ends of the rotating rod 403 in the strip-shaped limiting groove 4021, the two external threads are arranged in opposite directions, then screw hole moving blocks 405 which are matched with the two external threads are arranged at two ends of the strip-shaped limiting groove 4021, and the lower ends of the two screw hole moving blocks 405 are connected with clamping blocks 406.
In order to prevent the object from slipping due to insufficient clamping force of the two clamping blocks 406, referring to fig. 9 and 10, in this embodiment 3, trapezoidal grooves 4061 are further formed on the opposite sides of the two clamping blocks 406, a trapezoidal block 407 is disposed in each of the trapezoidal grooves 4061, and a compression spring 408 is disposed between the lower end of the trapezoidal block 407 and the bottom wall of the trapezoidal groove 4061. The outer end faces of the trapezoidal blocks 407 projecting out of the trapezoidal grooves 4061 are then attached with the clamp plates 409. Meanwhile, in order to increase the friction force to the object, rubber anti-slip layers 410 are further provided on the opposite sides of the two clamping plates 409.
This embodiment 3 is through further improving the setting to material mechanism 4 is grabbed in the antiskid, when drawing close two grip blocks 406 each other with the object centre gripping through rotating second rocker 404, what is used in object surface is two grip blocks 409, and two grip blocks 409 have received the guide effect of dovetail groove 4061 and dovetail block 407, heavy as the object of centre gripping, can make two dovetail blocks 407 move down along dovetail groove 4061 under the effect of frictional force, and two dovetail blocks 407 at the in-process of removing down can further be close to each other, thereby exert bigger clamping-force to the object through grip block 409 and rubber skid resistant course 410, can effectively avoid taking place the slippage because of the clamping-force to the object is not enough, greatly guaranteed the security when carrying out the object.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
