[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0017] See also Figures 1 to 3 The utility model provides a technical solution: a bag clamping device, including a clamp 1 and a rubber clamping block 2 symmetrically arranged on the inner side of the clamp 1, a replaceable connecting mechanism is arranged between the rubber clamping block 2 and the clamp 1, and a docking guide mechanism is arranged at the top of the clamp 1. The replaceable connecting mechanism includes: a connecting limit assembly and a positioning assembly; the connecting limit assembly is arranged at the connection between the rubber clamping block 2 and the clamp 1; the positioning assembly is arranged on the side of the clamp 1 and connected with the rubber clamping block 2.

[0018] In this embodiment, preferably, the connection limit assembly includes a connection groove 100 symmetrically opened on the inner side of the clamp 1 and a connection block 101 symmetrically fixed on the end of the rubber clamping block 2. The rubber clamping block 2 can be connected to the clamp 1 by snapping the connection block 101 with the connection groove 100.

[0019] In this embodiment, preferably, operating grooves 200 are symmetrically provided on both sides of the rubber clamping block 2 to facilitate operation of the rubber clamping block 2 .

[0020] In this embodiment, preferably, a limiting groove 300 and a built-in groove 301 are provided on one side of the connecting block 101 and on one side of the inner wall of the connecting groove 100; a limiting buckle 302 is arranged inside the built-in groove 301; the limiting buckle 302 is engaged and connected with the limiting groove 300, so that the connecting block 101 can be temporarily limited inside the connecting groove 100; a telescopic spring 303 is connected between the limiting buckle 302 and the built-in groove 301 to facilitate driving the limiting buckle 302 to reset and bounce up; sliding grooves 400 and sliders 401 symmetrically fixed on both sides of the limiting buckle 302 are symmetrically provided on both sides of the inner wall of the built-in groove 301; the sliders 401 are slidably connected with the sliding grooves 400, so as to play a guiding role when the limiting buckle 302 moves.

[0021] In this embodiment, preferably, the positioning assembly includes a positioning hole 500 opened at the end of the rubber clamping block 2 and a screw hole 501 penetrating through the inner side of the clamp 1. A positioning screw 502 is provided on the side of the clamp 1 and passes through the screw hole 501 and is connected to the positioning hole 500. The positioning screw 502 is screwed together and fixedly connected with the positioning hole 500, so that the rubber clamping block 2 can be connected to the clamp 1.

[0022] In this embodiment, preferably, the docking guide mechanism includes a docking groove 600 provided at the top of the clamp 1 and a docking block 601 symmetrically fixed inside the docking groove 600, so as to play a docking guide role when the lifting mechanism is connected to the clamp 1.

[0023] The working principle and use process of the utility model: when the rubber clamping block 2 needs to be replaced, the positioning screw 502 is first loosened to make its end withdraw from the inside of the positioning hole 500 and screw into the inside of the screw hole 501, so that the positioning of the rubber clamping block 2 can be released, and then the rubber clamping block 2 is pulled through the operating groove 200 to drive the connecting block 101 to withdraw from the inside of the connecting groove 100 and squeeze the limiting buckle 302. The limiting buckle 302 is squeezed by the external force to withdraw the telescopic spring 303 from the inside of the limiting groove 300 and retract into the inside of the built-in groove 301, and at the same time drive the slider 401 to slide in the inside of the slide groove 400 to play a moving guiding role, so that the connecting block 101 can be withdrawn from the inside of the connecting groove 100. Then, replace the rubber clamping block 2 of different types, fit the rubber clamping block 2 with the inner side of the clamp 1, so that the connecting block 101 is embedded in the connecting groove 100. At this time, the limiting buckle 302 is reset from the inside of the built-in groove 301 under the action of the telescopic spring 303 and pops out and is stuck in the inside of the limiting groove 300, so that the connecting block 101 can be temporarily limited, and the positioning hole 500 and the screw hole 501 can be accurately aligned, and then the positioning screw 502 is tightened to rotate inside the screw hole 501 and screwed and fixedly connected with the positioning hole 500, so that the rubber clamping block 2 can be positioned. When it is necessary to connect the lifting mechanism to the clamp 1, the docking groove 600 and the docking block 601 can play a docking guide role.
