[0017] Through the above technical solution: the arc design can protect the patient's esophagus and greatly improve the use effect.

[0018] As a preferred embodiment, one end of the grab hook away from the fixing ring is fixedly connected with a rubber pad.

[0019] Through the above technical solution, the esophagus can be further protected from damage, and the use effect is further improved.

[0020] Compared with the prior art, the advantages and strengths of the utility model are:

[0021] In the utility model, the device can pull the pull rope to pull the fixed block, which drives the connecting rod through the fixed block, and then pulls four grab hooks through the connecting rod. The grab hooks can be used to clamp the objects. Compared with the design of double grab hooks, the clamping effect is greatly improved, the work efficiency is greatly improved, and the operation quality and use efficiency are greatly improved compared with traditional devices.

[0028] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. However, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. Example

[0030] like Figure 1-Figure 4As shown, the utility model provides a technical solution: it includes a fixing ring 1, one side of the fixing ring 1 is equidistantly connected to four grabbing hooks 2, and the four grabbing hooks 2 can better clamp objects, and the ends of the grabbing hooks 2 away from the fixing ring 1 are provided with bends, which can be more convenient to clamp and improve the use effect, and the ends of the grabbing hooks 2 away from the fixing ring 1 are all arc-shaped, and the ends of the grabbing hooks 2 away from the fixing ring 1 are fixedly connected to rubber pads, and the arc design and the rubber pads can protect the esophagus from injury, further improving the use effect, and one side of the grabbing hooks 2 is rotatably connected to a connecting rod 3 A fixed block 4 is rotatably connected between the ends of the four connecting rods 3 away from the grab hook 2, and the connecting rod 3 can be driven by the fixed block 4, and then the grab hook 2 is driven. A pull rope 5 is fixedly connected to the side of the fixed block 4 close to the connecting rod 3. The end of the pull rope 5 away from the fixed block 4 passes through the fixed ring 1 and extends to the outside of the fixed ring 1. The end of the pull rope 5 away from the fixed block 4 is fixedly connected to a T-shaped slider 6. Two pull rings 7 are fixedly connected to the outside of the T-shaped slider 6. The pull rope 5 can be fixed by the T-shaped slider 6. At the same time, the pull ring 7 can be used to conveniently pull the T-shaped slider 6 and the pull rope 5, which greatly improves the feel of use. Example

[0031] like Figure 1-Figure 4 As shown, a first sleeve 8 is fixedly connected to the outer side of the fixing ring 1, a hose 9 is fixedly connected to one end of the first sleeve 8, and a second sleeve 10 is fixedly connected to the end of the hose 9 away from the first sleeve 8. The device can be wrapped by the first sleeve 8, the second sleeve 10 and the hose 9. At the same time, the hose 9 can facilitate the device to be inserted into the digestive tract, which greatly improves the use effect of the device. Two slide grooves 11 are provided on the second sleeve 10, and the T-shaped slider 6 is slidably connected to the slide groove 11. A handle 12 is fixedly connected to the end of the second sleeve 10 away from the hose 9, and the handle 12 can support the palm of the user, which greatly improves the fixing effect.

[0032] Working principle: Use the palm of your hand to hold the handle 12, insert your finger into the pull ring 7, and put the device into the patient's esophagus.
