Referring to fig. 1, in order to reduce the clamping force of the user, the elastic coefficient of the tension spring 3 is three times of the elastic coefficient of the tightening limiting spring 8, so that the pulling force of the tension spring 3 is three times greater than the elastic force of the tightening limiting spring 8, so that the driven floating block 12 has enough force to pull, and the tightening limiting spring 8 can determine the same clamping force for different people by its own elastic force.

Referring to fig. 1, in order to make a person feel more comfortable when the person is clamped, the inner fastening bag 4 is made of soft stretchable rubber, and the rubber protective layers are wrapped on the outer sides of the driving floating block 1 and the driven floating block 12, so that the inner fastening bag 4 can be expanded, and the person can be clamped without discomfort due to excessive local clamping force.

Referring to fig. 1, in order to keep the driving floating block 1 and the driven floating block 12 in a normal state with a maximum opening degree, so that a user can directly insert the driving floating block 1 and the driven floating block 12 into the body during rescue, a pull rope 2 located in the inner cavity of the driving floating block 1 is fixedly installed at one end of a movable tube 5, one end of the pull rope 2 penetrates out of the side wall of the driving floating block 1, a set of mutually adaptive locking blocks 9 are installed on the side wall of a driving block 11 and the outer side wall of the driven floating block 12, and the side wall of the pull rope 2 surrounds the outer side walls of the driving floating block 1 and the driven floating block 12 and is movably installed with the locking block 9, so that when the lantern ring 10 is directly taken out of the locking block 9 during use, clamping and fixing contact can be realized, thereby directly facilitating clamping of the user, and at the same time, in order to prevent the phenomenon that the inner cavity of the driving floating block 1 is contacted and flowed out due to continuous drawing of the pull rope 2 from the inner cavity of the driving floating block 1, therefore, a sealed sliding sleeve is arranged on the inner wall of the active floating block 1 and at the sliding position of the pull rope 2, a lantern ring 10 is fixedly installed at one end of the pull rope 2, and the lantern ring 10 is sleeved on the locking block 9 to realize fixation.

Referring to fig. 1 and 2, in order to realize that the lock block 9 and the collar 10 are fixed to each other to open the driving floating block 1 and the driven floating block 12 during the storage process, the two lock blocks 9 are connected to each other by a user during the use process, so that the number of the lock blocks 9 is two, the outer side walls of the two lock blocks 9 are provided with arc-shaped fixing parts 92, the top end of the lock block 9 is provided with an inclined plane type assembling part 90, and the inner side wall of the lock block 9 is provided with a C-shaped anti-falling part 91, so that the collar 10 is fixed by the fixing parts 92 to the inner wall of the collar 10 during the use process of the two lock blocks, and the collar 10 is directly pushed to the anti-falling part 91 through the assembling part 90 when the collar 10 is combined with another user, so that the collar 10 is directly placed between the anti-falling parts 91, and the collar 10 is pulled by the anti-falling part 91, avoiding the phenomenon that the lantern ring 10 is pulled out.

Referring to fig. 3, in order to prevent the collar 10 from separating from the anti-separation portion 91 during the connection process, the end surface of the collar 10 is designed to be crescent, and the length of the end surface of the collar 10 is at least one centimeter longer than the length of the movement stroke of the driving block 11, so that the fixing portion 92 is more easily separated by the crescent, and the collar 10 of the crescent is not easily separated from the anti-separation portion 91, on the other hand, the width of the collar 10 is controlled, so that the collar 10 is subjected to the elastic force of the tightening spring 8 after being inserted, and at the same time, only the speed of adjustment between the driving floating block 1 and the driven floating block 12 is reduced, i.e. after the collar 10 is inserted by the driving block 11, the medium throughput between the communication hole 6 and the liquid discharge groove 7 is relatively reduced by the driving block 11, but the original adjustment is not hindered, and the clamping force between the locking blocks 9 is further enhanced by the elastic force of the tightening spring 8, on the other hand, the one-centimeter setting is that the lantern ring 10 is made of rubber, the lantern ring is extruded when being inserted, and after the lantern ring is separated, the lantern ring 10 is hooked by the anti-separation part 91, so that the lantern ring is not easy to separate, and even if the lantern ring 10 is stressed to open the locking block 9 so that the driving block 11 completely separates the communication hole 6 from the liquid discharge groove 7, the locking block 9 and the lantern ring 10 can not separate.

This application is in order to prevent when fixed, breaks away from initiative kicking block 1 and driven kicking block 12 to it realizes the fixed to stay cord 2 to offer the U-shaped groove at the lateral wall of initiative kicking block 1 and driven kicking block 12.

The working principle of the invention is as follows:

and (3) normal state: the locking blocks 9 are manually pulled and are close to each other, and after the pull rope 2 is pulled to surround the side walls of the driving floating block 1 and the driven floating block 12, the locking blocks 9 are sleeved with the lantern ring 10, so that the inner ring between the driving floating block 1 and the driven floating block 12 is maximized through the lantern ring 10;

during use, a user wears the inner rings of the driving floating block 1 and the driven floating block 12, then the lantern ring 10 is manually separated from the locking block 9, after the lantern ring 10 is separated, the driving block 11 can pull down under the elastic pull of the tension spring 3, the driving block 11 is close to the driving floating block 1 by pulling the movable tube 5, and in the moving process of the driving block 11, the tightening limiting spring 8 can be simultaneously extruded and the driven floating block 12 can be deflected towards the driving floating block 1, meanwhile, a medium in the inner cavity of the driving floating block 1 can be extruded into the inner cavity of the driven floating block 12 through the liquid discharge groove 7 due to the extrusion of the movable tube 5, and flows into the inner cavity of the inner tightening bag 4 through the communication hole 6, and the inner tightening bag 4 can be expanded;

after the inner walls of the driven floating block 12 and the driving floating block 1 clamp a person falling into water, the driven floating block 12 has certain resistance in the process of attaching, so that the driving block 11 continues to compress the tight limiting spring 8, the liquid discharge tank 7 is separated from the communicating hole 6 through the driving block 11, the tension spring 3 of the driving floating block cannot clamp the driving floating block 1 and the driven floating block 12 through pulling in a sealed space formed by the inner cavity of the driving floating block 1, and the purpose of clamping the person is achieved;

then, when a person who falls into water needs to help a person beside the clamping device, the lantern ring 10 can be inserted into the space between the locking blocks 9 on another person who falls into water, the lantern ring 10 is fixed through clamping between the locking blocks 9, and when the person falls into water, the driving block 11 can be pushed against the driven floating block 12 by the elastic force of the tightening limiting spring 8, so that the lantern ring 10 can be stably clamped between the locking blocks 9, and meanwhile, when the lantern ring 10 is about to be separated by factors such as shaking, the locking blocks 9 can hook the inner wall of the lantern ring 10, so that the person cannot be separated easily;

finally, when the person falling into the water is rescued, the person falling into the water can be dragged by pulling the lantern ring 10, and in the pulling process, because the inner cavity of the driving floating block 1 is still in a sealed space, the pulling force of the person falling into the water cannot act on the person falling into the water, so that the lantern ring 10 is ensured to apply no large pulling force, the clamping force between the driving floating block 1 and the driven floating block 12 to the person falling into the water cannot be increased, and the phenomenon that the person falling into the water is clamped uncomfortably cannot be generated.
