Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example (b):

referring to figures 1-3 of the drawings,

the embodiment provides a simple mechanical clamping jaw driven by a single motor, which comprises a mounting shell 1, wherein an oil groove 101 is formed in one side inside the mounting shell 1, an oil inlet 1011 is formed in one side of the top of the oil groove 101, a cotton block 1012 is arranged inside the oil groove 101, an adjusting groove 102 is formed in the bottom of the oil groove 101, a connecting hole 103 is formed between the oil groove 101 and the adjusting groove 102 in a penetrating manner, an oil outlet 104 is formed in the bottom of the adjusting groove 102, a flow guide pipe 105 is fixedly connected to the bottom of the oil outlet 104, an adjusting rod 106 is slidably connected inside the oil outlet 104, a through hole 1061 is formed inside the adjusting rod 106, two positioning gears 107 are arranged at the bottom of the inner wall of the mounting shell 1, a motor 2 is arranged at the top inside the mounting shell 1, a threaded screw rod 201 is drivingly connected to the bottom of the motor 2, the two positioning gears 107 are meshed with the outer side of the threaded screw rod 201, a lifting frame 3 is meshed with the outer side of the threaded screw rod 201, two sides of the mounting shell 1 are rotatably connected with a connecting frame 4 through a rotating shaft, 4 one ends of both sides link all are connected with clip 5 through the pivot rotation, and 5 one ends of two clips all rotate through the pivot and connect at crane 3 surfaces.

Further, the installation shell 1 is made of an aluminum alloy material, the aluminum alloy material has a lighter metal weight compared with other metal materials, the overall weight of the mechanical clamping jaw can be reduced, the mechanical clamping jaw is convenient to install and detach, meanwhile, the aluminum alloy material has better metal structure strength and corrosion resistance, and the motor 2 and the threaded screw rod 201 can be effectively protected from being damaged while being adaptive to various working environments.

Further, two clips 5 are located same water flat line, when clip 5 needs the centre gripping, start motor 2 and drive screw thread lead screw 201 rotatory for 3 rotatory rises of crane, thereby clip 5 will be driven the change angle by crane 3 this moment, and clip 5 receives the restriction that comes from link 4 simultaneously, and 5 one end of both sides clip can rise along with crane 3, and the other end then can evenly contract to inside, thereby reaches the purpose of stable centre gripping.

Furthermore, the size of the adjusting rod 106 is matched with the size of the inner wall of the adjusting groove 102, when the adjusting rod 106 is pressed into the adjusting groove 102, the lubricating oil flows out of the cotton block 1012, enters the adjusting groove 102 through the connecting hole 103, passes through the through hole 1061 and flows to the oil outlet 104, and the situation that the lubricating oil leaks out before the adjusting rod 106 is not pressed due to the fact that the size of the inner wall of the adjusting groove 102 is too large is prevented.

Further, screw thread lead screw 201 bottom is provided with the dog, and the diameter of dog is greater than screw thread lead screw 201's diameter, and when crane 3 descends and crosses lowly, crane 3 continues to move down and can contact the dog, and the dog will prevent crane 3 to continue to descend, prevents that crane 3 from dropping screw thread lead screw 201 and leading to damaging the condition of spare part.

Further, 5 inboards of two clips all are provided with the rubber gasket for at the in-process increase of 5 centre grippings of clip and the frictional force of holding object, thereby guarantee the stability of holding object, avoid the holding object to drop, improved mechanical clamping jaw's practicality, the rubber gasket provides the cushioning effect simultaneously, prevents that 5 sharp-pointed injuries of clip from holding the object, has improved mechanical clamping jaw's security.

When the utility model is used, a user firstly injects lubricating oil into the oil inlet 1011, the lubricating oil flows into the oil groove 101 and is absorbed by the cotton block 1012, then the simple mechanical clamping jaw is connected on a using device, the motor 2 is started to drive the screw thread lead screw 201 to rotate in the forward direction, so that the lifting frame 3 meshed and connected with the screw thread lead screw 201 is lifted, at the same time, the clamp 5 is driven by the lifting frame 3 to change the angle, meanwhile, the clamp 5 is limited by the connecting frame 4, one end of the clamps 5 at two sides can lift up along with the lifting frame 3, the other end can uniformly contract towards the inside, when the clamp 5 carries out clamping action, as the rubber gaskets are arranged at the inner sides of the two clamps 5, the stability of clamped objects is ensured, meanwhile, the rubber gaskets provide a buffer effect, the clamp 5 is prevented from clamping the sharp-pointed objects, when the mechanical clamping jaw needs to be loosened, the user starts the motor 2 and makes the threaded screw rod 201 rotate reversely, so that the lifting frame 3 descends, the clamp 5 is driven by the lifting frame 3 to change the angle, meanwhile, the clamp 5 is limited by the connecting frame 4, one end of the clamp 5 at two sides descends along with the lifting frame 3, the other end can be opened to the outside uniformly, the purpose of loosening the clamp 5 is achieved, when the lifting frame 3 descends too low, because the bottom end of the threaded screw rod 201 is provided with a stop block, the diameter of the stop block is larger than that of the threaded screw rod 201, the lifting frame 3 continuously moves downwards to contact the stop block, the condition that the threaded screw rod 201 is fallen off by the lifting frame 3 to damage parts is prevented, if the threaded screw rod 201 needs to be lubricated, the user presses the adjusting rod 106 into the adjusting groove 102, because the adjusting rod 106 is proper in size with the inner wall of the adjusting groove 102, when the adjusting rod 106 is completely matched with the adjusting groove 102, the through hole 1061 is located between the connecting hole 103 and the oil outlet hole 104, and the lubricating oil flows out of the cotton block 1012 and enters the inside of the regulating groove 102 through the connecting hole 103, and flows to the oil outlet 104 through the through hole 1061, thereby preventing the leakage of the lubricant before the adjustment lever 106 is not pressed due to the oversize inner wall of the adjustment groove 102, the lubricating oil flowing to the oil outlet 104 is guided to the top of the right positioning gear 107 by the guide pipe 105 and drops, and as the positioning gear 107 and the threaded screw 201 rotate in a meshed manner, the threaded screw 201 is lubricated by the lubricating oil carried by the positioning gear 107, when lubrication is not required, the adjustment lever 106 is pulled out a portion so that the through hole 1061 is separated from the coupling hole 103, thereby the rod body part of the adjusting rod 106 can block the connecting hole 103, the lubricating oil is prevented from leaking out to cause waste, the simple mechanical clamping jaw driven by the single motor has the characteristics of reasonable linkage and convenience in lubrication.

The above is only the preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, without departing from the concept of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
