As shown in fig. 3, the first clamping body 10 includes a body 100, and a cavity 102 having an opening 101 is disposed on the body 100. As shown in fig. 1, the second clip body 20 has a main body portion 200 and a connecting column 210 disposed on the main body portion 200, the connecting column 210 has an inward recessed held portion 211, the held portion 211 enters the cavity 102 from the opening 101, for example, moves rightward from the left side in fig. 3 along the horizontal direction in fig. 3, and after the held portion 211 enters the cavity 102 from the opening 101, the held portion 211 can be held and fixed by the inner wall of the cavity 102.

As shown in fig. 3, the body 100 includes at least a first end 110 and a second end 120, and the first end 110 and the second end 120 are understood as having two ends along the length direction of an elongated workpiece, and the two ends can be referred to as the first end 110 and the second end 120 after a middle portion of the workpiece is bent. In the embodiment shown in fig. 3, after the workpiece is bent in the middle, a cavity 102 having an opening 101 is substantially enclosed, and in the view shown in fig. 3, the first end 110 and the second end 120 are respectively disposed on the upper and lower sides of the opening 101 of the body 100. In some embodiments, if the middle of the long workpiece has other protruding portions, after bending, the protruding portions can also be referred to as third ends on the body 100. That is, in some embodiments, the body 100 may further include a third end, etc.

Wherein the first end 110 is provided with a first flared ear 111, and the second end 120 is provided with a second flared ear 121. Through setting up first flaring ear 111 and second flaring ear 121, the cooperation pliers uses, two pointed ends of pliers insert respectively in first flaring ear 111 and second flaring ear 121, two pointed ends of pliers open in order to exert tension, can drive first flaring ear 111 and second flaring ear 121 and keep away from each other, thereby make opening 101 open slightly, be convenient for second joint body 20 held the portion 211 by the card and pass through opening 101 and get into cavity 102, it shifts out cavity 102 through opening 101 to be held the portion 211 by the card during still convenient to dismantle on the same principle. Thereby facilitating the disassembly.

The first engaging member 10 generally has a certain elasticity, i.e. can be elastically deformed. In a natural state, the opening 101 of the first engaging body 10 is smaller than the outer diameter of the held portion 211. During assembly, tension is applied to the first flaring tab 111 and the second flaring tab 121, so that the body 100 is elastically deformed to expand the size of the opening 101 to be slightly larger than the outer diameter of the clamped portion 211, after the clamped portion 211 enters the cavity 102 from the opening 101, the tension applied to the first flaring tab 111 and the second flaring tab 121 is removed, the body 100 is to recover the original shape due to the elastic force, so that the opening 101 is reduced, the opening 101 is reduced to be smaller than the outer diameter of the clamped portion 211, clamping and positioning of the second clamping body 20 are realized, and when clamping and positioning are performed, the inner wall of the cavity 102 can abut against the clamped portion 211.

For example, as shown in fig. 3, the first clip body 10 may be integrally formed as a sheet-like structure. The integration means that the first clamping body 10 is integrally composed of a structural member, and each part of the structural member is fixedly connected with the adjacent part, but is not movably connected. The integrated first clamping body 10 has the advantages of small volume, light weight, high strength and convenient processing.

As shown in fig. 3, the first flared ear 111 and the second flared ear 121 have the same structure and are both closed loop structures. By the arrangement, the first flaring lug 111 and the second flaring lug are closed without a fracture, so that the first flaring lug 111 and the second flaring lug 121 are strong in integrity and higher in strength, the first flaring lug 111 and the second flaring lug 121 can bear tension applied by opening of two tips of pliers and are not easy to deform, and the overall strength is improved.

Wherein the first and second flared ears 111, 111 may have a circular lumen 131 as shown in fig. 3. Fig. 4 is a schematic structural diagram of the first clamping body 10 in another embodiment, and as shown in fig. 4, the first flared ear 111 and the second flared closed annular structure may further have a polygonal cavity 132 shown in fig. 4. The polygon can be a triangle, a quadrangle or a pentagon. Of course, in some embodiments, the circular lumen 131 may be replaced with an elliptical lumen.

In one embodiment, as shown in fig. 3, the first clip body 10 includes a first guide wall 311 and a second guide wall 312, and the first guide wall 311 and the second guide wall 312 are disposed outside the cavity 102. The first guide wall 311 and the second guide wall 312 gradually come close at one end near the opening 101. When the clamped part 211 on the connecting column 210 moves from the left side to the right side in fig. 3, the clamped part 211 can abut against the first guide wall 311 and the second guide wall 312, and as the clamped part 211 continuously moves towards the cavity 102, the clamped part 211 can support the first guide wall 311 and the second guide wall 312 to two ends, so that the opening 101 is enlarged, and the clamped part 211 can conveniently enter the cavity 102 from the opening 101.

The third guide wall 313 and the fourth guide wall 314 are gradually closed at an end near the opening 101. When the clamped portion 211 of the connecting column 210 needs to be removed from the cavity 102, as shown in fig. 3, the clamped portion 211 moves to the left from the cavity 102 in fig. 3, the clamped portion 211 can abut against the third guide wall 313 and the fourth guide wall 314, and as the clamped portion 211 continuously moves to the outside of the cavity 102, the clamped portion 211 can prop open the third guide wall 313 and the fourth guide wall 314, so that the opening 101 is enlarged, and the clamped portion 211 can be conveniently removed from the cavity 102.

In one embodiment, as shown in fig. 3, a supporting wall 315 is further disposed in the cavity 102, and the supporting wall 315 is disposed between the third guiding wall 313 and the fourth guiding wall 314 along the circumferential direction of the cavity 102. When the clamped part 211 is in the cavity 102, the third guide wall 313, the fourth guide wall 314 and the support wall 315 are supported on the clamped part 211 together to position the clamped part 211, so that the clamped part 211 is stably fixed in the cavity 102. As shown in fig. 3, inside the cavity 102, along the circumferential direction of the cavity 102, the body 100 is provided with cavities m1 and m2 on both sides of the support wall 315, respectively. The body 100 includes an inner surface 112 and an outer surface 113, the surface of the cavity 102 is referred to as the inner surface 112, and the surface away from the inner surface 112 is the outer surface 113. The dimension between the inner surface 112 and the outer surface 113 of the body 100 is referred to as the width of the body 100. The width of the body 100 at the supporting wall 315 is L1, and the width of the body 100 on both sides of the supporting wall 315 (i.e. the dimensions at cavities m1 and m 2) is L2 and L3, where L1 is greater than L2 and L1 is greater than L3, and L2 and L3 may be equal or slightly different. Since the main body 100 can be elastically deformed by the pliers in the present application, the sizes of L2 and L3 are both smaller than L1, and the main body 100 is more easily elastically deformed at the corresponding positions of L2 and L3, so that the pliers can elastically deform the main body 100 by applying a smaller tension.
