The electric push rod 5 can drive the sliding rod 4 to move, in particular, the electric push rod 5 is arranged in a mounting groove 6 opened in the hook body 1, and the electric push rod 5 is connected with the slide rod 4 through a fixed sleeve fixedly connected with the output rod, a cover plate is arranged at the notch of the mounting groove 6, the electric push rod 5 is arranged on the cover plate, the cover plate is mutually connected with the hook body 1 through a bolt, the electric push rod 5 can be stably positioned in the mounting groove 6 after the cover plate is connected with the hook body 1, the cover plate can protect the electric push rod 5, two ends of the slide rod 4 respectively extend into the slide grooves formed on the rotating rod 2 through the through grooves 7 formed on the groove walls at two sides of the mounting groove 6, when the output rod of the electric push rod 5 moves, the sliding rod 4 is driven to move along the direction of the through groove 7, and at the moment, the rotating rod 2 rotates around the fixed shaft under the action of the sliding groove on the rotating rod 2.

The slide rod 4 can be conveniently installed and kept stable, specifically, the slide rod 4 comprises a main rod 401, one end of the main rod 401 is fixedly connected with a fixing plate 402, the other end of the main rod 401 is connected with a baffle 403 in a meshed mode, the fixing plate 402 and the baffle 403 are both larger than the main rod 401 in size, the main rod 401 can penetrate through a sliding groove in the rotating rod 2, the fixing plate 402 and the baffle 403 cannot penetrate through a sliding groove in the rotating rod 2, the baffle 403 is connected with the main rod 401 in a meshed mode through a screw fixedly connected with the baffle 403, one end of the main rod 401 can penetrate through the sliding groove in the rotating rod 2, the penetrating groove 7 and a fixing sleeve on an output rod of the electric push rod 5 during installation, and then the baffle 403 is connected with the main rod 401 in a meshed mode.

In order to make the stable motion of bull stick 2, set up and stabilize axle 8 and arc groove 9, specifically speaking, the one end fixedly connected with of bull stick 2 keeping away from swivel hook 3 stabilizes axle 8, stabilize axle 8 and extend to the hook main part 1 and go up to open the arc groove 9 that has in, stabilize axle 8 and arc groove 9 sliding connection, under the effect of stabilizing axle 8 and arc groove 9, bull stick 2 can more stable rotation.

The rotating rod 2 can be connected with the rotating hook 3 in the following manner, specifically, the rotating hook 3 is rotatably connected with the hook body 1 through a connecting plate 10 fixedly connected with the rotating hook 3, the connecting plates 10 are fixedly connected with both sides of the rotating hook 3, the two connecting plates 10 are rotatably connected with the hook body 1 through connecting shafts, one end, far away from the connecting plates 10, of the rotating hook 3 is movably clamped with a clamping frame 11, the upper end of the outer side of the rotating hook 3 is clamped with the clamping frame 11 (the left side of the rotating hook 3 is the outer side as shown in fig. 4) as shown in fig. 4, the clamping frame 11 is fixedly connected with the rotating rod 2, and when the rotating rod 2 rotates clockwise as shown in fig. 1, the clamping frame 11 is driven to ascend, so that the clamping frame 11 is separated from the clamping connection with the rotating hook 3;

the atress extension line when wire rope suspends the heavy object passes the tie point of connecting plate 10 with hook main part 1, this kind of setting can be when suspending the heavy object card frame 11 can not receive the influence of heavy object gravity with being connected of swivel hook 3, even the weight of heavy object is great can not make swivel hook 3 produce the strength that deflects like this, thereby can make card frame 11 can easily follow the motion of bull stick 2, make things convenient for falling the experimental going on more, and the focus of swivel hook 3 is skew to one side of keeping away from hook main part 1, when card frame 11 and swivel hook 3 are not in mutual joint, swivel hook 3 can outwards overturn automatically under the action of gravity of self, thereby with wire rope disconnection, make the heavy object begin the weight to drop down.

GSS in figure 2 refers to wire rope.

The working principle is as follows: when in use, the rotating hook 3 and the clamping frame 11 can be clamped with each other, then the steel wire rope passes through the rotating hook 3 and is connected with a device to be tested with each other, and then the steel wire rope can be hoisted through the hook main body 1, so that the device to be tested is suspended;

after the device that needs the experiment is unsettled, the staff can start electric putter 5, make its output pole go slide bar 4 to right-hand top as shown in figure 1 to can make bull stick 2 begin to rotate clockwise, make card frame 11 break away from the joint with rotating hook 3, this moment because rotating hook 3 focus is skew to the one side of keeping away from hook main part 1, so rotating hook 3 can automatic outwards overturn, break away from the connection with wire rope, at this moment the testing arrangement will drop downwards, the simulation of preventing weighing down the experiment is carried out smoothly.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
