The first actuating arm 1, the second actuating arm 2, and the telescopic clamp 3 are integrally formed, preferably, of the same material and formed integrally through the same manufacturing process, for example, by elastic sheets, and the combination of the first actuating arm 1 and the second actuating arm 2 is in a V-shape as viewed from the axial direction of the telescopic clamp 3, the V-shaped first actuating arm 1 and the V-shaped second actuating arm 2 are located above the telescopic clamp 3, and the projections of the first actuating arm 1, the second actuating arm 2, and the telescopic clamp 3 on a plane perpendicular to the axial direction of the telescopic clamp 3 have an intersection. At the junctions of the telescopic collar 3 with the first and second actuating arms 1, 2, the first and second actuating arms 1, 2 are tangent to the telescopic collar 3, respectively. Alternatively, the first actuator arm 1, the second actuator arm 2 and the telescopic clamping ring 3 may be bent from a spring wire, for example using 0.8mm stainless steel wire.
The first actuator arm 1 is inclined at an angle of between 20-50 degrees, preferably 30 degrees, relative to the second actuator arm 2. The diameter of the telescopic clamping collar 3 may be between 2mm-10mm, in the embodiment of fig. 1 the diameter of the telescopic clamping collar 3 is 5 mm. Here, the diameter of the retractable collar 3 means the diameter of the retractable collar in a natural state of the elastic clip.
Fig. 1 shows the elastic clip in a natural state, i.e. when no force is applied to the elastic clip, in which the telescopic clamping ring is contracted and the object to be clamped, for example, a duct, is clamped and closed. When the clamping force needs to be released, the first actuating arm 1 and the second actuating arm 2 are clamped by two hands, force is applied in the direction shown by an arrow in fig. 1, the telescopic clamping ring is expanded, and the clamped object is released.
At the opening of the telescopic collar 3 of the non-closed circle, the first actuating arm 1 and the second actuating arm 2 are spaced apart in the axial direction of the telescopic collar 3, so that a clamped object can enter the telescopic collar 3 through the gap between the first actuating arm 1 and the second actuating arm 2, through the opening of the telescopic collar 3. In this way, it is possible to put the object to be gripped in the telescopic clamping collar 3 and to take the object to be gripped out of the telescopic clamping collar 3, and therefore it is important that the telescopic clamping collar 3 has an opening and that there is a gap between the first actuating arm 1 and the second actuating arm 2.

The inner cushion 4 may be constructed of rubber or other resilient material. Through set up interior pad 4 on the inside wall of flexible clamping ring 3, can be with the clamping-force homogenization of being used in on the object by the centre gripping, be favorable to keeping the clamping-force even unanimous to interior pad 4 helps protecting by the centre gripping object, prevents to be pressed from both sides by flexible clamping ring 3 by the centre gripping thing bad, especially when centre gripping plastic hose.
Advantageously, said inner pad 4 is also configured as a non-closed circle, the opening of the inner pad 4 of the non-closed circle communicating with the gap between the first actuator arm 1 and the second actuator arm 2. Therefore, the clamped object can enter the telescopic clamping ring 3 through the gap between the first actuating arm 1 and the second actuating arm 2, the opening of the inner pad and the opening of the telescopic clamping ring 3, so that the clamped object is sleeved in the telescopic clamping ring 3, and the clamped object can be taken out of the telescopic clamping ring 3.
Preferably, said inner pad 4 extends from the inside to the outside of the telescopic collar 3, wrapping the edges of the telescopic collar 3. That is, the inner pad 4 includes a portion attached to the inner side wall of the telescopic band 3 and a portion extending to the outside of the telescopic band 3 to wrap the edge of the telescopic band 3. Here, the edge of the telescopic clamp ring 3 refers to both ends of the telescopic clamp ring 3 in the axial direction thereof. Through wrapping the edge of flexible clamping ring 3 for the sharp edge of flexible clamping ring 3 can not harm by the centre gripping thing, also can protect the operator, prevents to be by flexible clamping ring 3 fish tail.
The inner pad 4 can advantageously be removed from the telescopic collar 3, so that the spring clip 10 can also be used when the diameter of the object to be clamped is large, simply by removing the inner pad 4 from the telescopic collar 3.
Further preferably, the telescopic clamping ring 3 of said elastic clamp 10 is completely surrounded by a protective sheath, even if the entire elastic clamp 10 is surrounded by a protective sheath, i.e. the first actuating arm 1, the second actuating arm 2 and the telescopic clamping ring 3 are all surrounded by a protective sheath.
Third embodiment
Fig. 3 shows an elastic clip according to a third embodiment of the invention, as shown in fig. 3, the elastic clip comprises a first actuating arm 1, a second actuating arm 2 and a telescopic clamping ring 3 which are integrally formed, wherein the first actuating arm 1 is arranged non-parallel with respect to the second actuating arm 2, and the telescopic clamping ring 3 is expandable after the first actuating arm 1 and the second actuating arm 2 are actuated and is contractible after the actuating force to the first actuating arm 1 and the second actuating arm 2 is released.
The difference from the first embodiment shown in fig. 1 is that: the resilient clip 10 further comprises a locking sleeve 5 for locking the relative angle between the first actuator arm 1 and the second actuator arm 2, the locking sleeve 5 comprising a base plate and two fixing tabs extending perpendicularly with respect to the base plate.
Advantageously, one of the first 1 and second 2 actuation arms is hinged on the internal side wall of a fixed plate.
As a further improvement of this embodiment, the elastic clip 10 further comprises a restraining chain, one end of which is connected to the outer side of the first actuating arm 1 and the other end of which is connected to the outer side of the second actuating arm 2, so that the restraining chain extends from the first actuating arm 1, bypasses the telescopic clamping ring 3 and terminates on the second actuating arm 2.
In order to improve the operability of the elastic clamp, rubber sleeves are arranged on the end parts, far away from the telescopic clamping ring 3, of the first actuating arm 1 and the second actuating arm 2, so that the elastic clamp is convenient to hold.
According to the utility model discloses an elasticity clamping, the part of the clamping-force of production is flexible clamping ring, and it is constructed for roughly circular, therefore the clamping face is the anchor ring, when the cylindrical cross-section of centre gripping by the centre gripping thing, the anchor ring can with by centre gripping thing in close contact with, the contact surface is bigger, consequently it is better to seal the effect to the clamping-force around by the centre gripping thing is even unanimous, and the centre gripping stability is good. In addition, the elastic clamp is very simple and convenient to operate, and after the telescopic clamping ring is sleeved on an object to be clamped, the operation can be completed only by manually clamping or releasing the actuating arm.
The utility model discloses an elasticity clamping can use with the cooperation of the three bag prostate expansion conduit subassemblies in four chambeies that the designer of this application designed for this conduit subassembly of location, after three bag prostate expansion conduit subassemblies in four chambeies were inserted patient urethra, for preventing that the displacement of the possible inboard direction of taking place at any time of conduit subassembly from influencing the treatment, use elasticity clamping to carry the pipe along glans penis end portion after the location, prevent that the conduit subassembly from inwards sliding.
