[0001] The utility model relates to the technical field of clamping, in particular to a clamping mechanism with an adjustable gripping range. Background Art

[0002] When taking an item, it can be grasped through the clamping mechanism, thereby improving the efficiency of moving the item.

[0003] However, the prior art still has some shortcomings. In the prior art, it is not convenient to adjust the distance between the grippers according to the size of the objects to be gripped, thereby making it inconvenient to effectively grip objects of different sizes.

[0004] Therefore, we propose a clamping mechanism with adjustable gripping range to solve this problem. Utility Model Content

[0005] The purpose of the present utility model is to solve the problems raised in the above background technology and to propose a clamping mechanism with an adjustable gripping range.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] The cam is secured to the upper and lower surfaces of the chassis and is adapted to engage the driver of the chassis and to engage the driver of the chassis, wherein the cam is secured to the lower surface of the chassis and is adapted to engage the driver of the chassis.

[0008] Preferably, the lower end of the spring is fixedly connected to the upper surface of the mounting shell; and the upper end of the spring is fixedly connected to the lower surface of the connecting frame.

[0009] Preferably, the fixing block is slidably mounted on the inner surface of the connecting groove; and the lower surface of the guide rod is fixedly connected to the upper surface of the mounting shell.

[0010] Preferably, an anti-slip pad is fixedly connected to the upper surface of the clamping plate; and the output end of the motor is fixedly connected to one end of the connecting rod.

[0011] Preferably, the upper surface of the guide rod is fixedly connected to a limiting block.

[0012] The present invention provides a clamping mechanism with adjustable gripping range, through the arrangement of the pillar, the mounting shell, the slide groove, the connecting groove, the connecting shell, the fixing groove, the connecting plate, the connecting rod, the motor, the clamping plate, the anti-slip pad, the guide rod, the connecting frame, the fixing block and the spring. When the clamping plate is adjusted, the connecting frame is pushed upward, and the movement of the connecting frame drives the fixing block to move so that the fixing block leaves the fixing groove. The movement of the fixing frame causes the spring to stretch. When the fixing block leaves the fixing groove, the connecting shell can be pulled to move the connecting shell outward. After moving, the connecting frame is released, and the connecting frame will drive the fixing block into the fixing groove under the action of the spring rebound to fix the connecting shell, thereby realizing the adjustment of the gripping range of the clamping plate and improving the scope of application.

[0013] In the utility model, the clamping mechanism with adjustable gripping range can prevent the connecting frame from being separated from the guide rod by setting a limit block, thereby improving stability;

[0014] The utility model has reasonable structural design, simple operation and high reliability. BRIEF DESCRIPTION OF THE DRAWINGS
