[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present disclosure with reference to the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only some embodiments of the present disclosure, rather than all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art based on the present disclosure belong to the scope of protection of the present disclosure.

[0038] An embodiment of the present disclosure provides a connection assembly for connecting pipe A, such as Figures 1 to 9As shown in the figure, it includes: a connecting member 10, a pressing structure 20, a second positioning ring 30 and a sealing ring 40. Specifically: The connecting member 10 has at least two connecting ports 110, and the connecting ports 110 are used to dock with the pipe orifice a of the pipe A. A fluid passage 120 communicating with each connecting port is arranged inside the connecting member 10, and a first positioning ring 130 protruding from the outer surface is arranged on the outer surface of the connecting port 110; The pressing structure 20 includes a first semi-circular pressing ring 210 and a second semi-circular pressing ring 220, and the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220 can be assembled into a circular pressing and fixing ring 230; A positioning groove 240 matching with the first positioning ring 130 is arranged on the inner side of the pressing and fixing ring 230; The second positioning ring 30 is used to be fixedly sleeved on the outer side of the pipe orifice a of the pipe A; A part of the sealing ring 40 is sleeved on the outer side of the connecting port 110 and is in close contact with the first positioning ring 130, and another part of the sealing ring 40 is used to be sleeved on the outer side of the pipe orifice a of the pipe A and is in close contact with the second positioning ring 30; A first groove clamping part 250 matching with the sealing ring 40 and a second groove clamping part 260 matching with the second positioning ring 30 are also arranged on the inner side of the pressing and fixing ring 230.

[0039] When using a connection assembly of an embodiment of the present invention to connect pipe A, first, the second positioning ring 30 is sleeved on the outer side of the pipe mouth a of the pipe A, a part of the sealing ring 40 is sleeved on the outer side of the connecting port 110 and tightly abutted against the first positioning ring 130, and then the pipe mouth a of the pipe A with the second positioning ring 30 sleeved is inserted into the other part of the sealing ring 40, so that the pipe mouth a is docked with the connecting port 110, and the other part of the sealing ring 40 is tightly abutted against the second positioning ring 30, and then the first semicircular pressing ring 210 and the second semicircular pressing ring 220 of the compression fixing ring 230 are opened, so that the positioning groove 240 in the compression fixing ring 230 is docked with the first positioning ring 130, the first groove clamping part 250 in the compression fixing ring 230 is docked with the sealing ring 40, and the second groove clamping part 260 in the compression fixing ring 230 is docked with the second positioning ring 30, and finally, the first semicircular pressing ring 210 and the second semicircular pressing ring 220 are tightened to complete the connection between the connection assembly and the pipe A. According to a connection assembly in an embodiment of the present invention, the first positioning ring 130 is used to position the connection port 110 of the connector 10 to prevent the connection port 110 from axial displacement, the second positioning ring 30 is used to position the pipe mouth a of the pipe A to prevent the pipe mouth a from axial displacement, the sealing ring 40 is used to seal the portion where the connection port 110 and the pipe mouth a are connected to achieve a coaxial sealed connection between the connection port 110 and the pipe mouth a, and the clamping structure 20 is used to compress and fix the connection port 110 and the pipe mouth a after docking. Moreover, since the first positioning ring 130, the sealing ring 40 and the second positioning ring 30 are tightly abutted against each other, the connection port 110 and the pipe mouth a are squeezed and clamped together under the compression action of the clamping and fixing ring 230, thereby improving the connection stability of the pipes. Therefore, using a connection assembly in an embodiment of the present invention to connect pipes can achieve rapid positioning, sealed connection and compression and fixation of the connection port 110 and the pipe mouth a, thereby improving the installation efficiency and connection stability of the pipes.

[0040] In one embodiment of the present disclosure, the connector 10 has at least two connection ports 110, which may be two, three, or any other number, which is not limited in this application. Figure 1 As shown, the connector 10 has three connection ports 110 , and the three connection ports 110 can all be used to connect the pipe A. When the connector 10 has three connection ports 110 , the connector 10 is a three-way pipe that can connect three pipes A.

[0041] In one embodiment of the present disclosure, the inner diameter of the connecting port 110 of the connecting piece 10 is the same as the inner diameter of the pipe mouth a of the pipe A, and the outer diameter of the connecting port 110 of the connecting piece 10 is the same as the outer diameter of the pipe mouth a of the pipe A, so as to facilitate the coaxial sealing connection between the connecting port 110 and the pipe mouth a.

[0042] In one embodiment of the present disclosure, the positioning groove 240 in the pressing and fixing ring 230 is in sliding fit with the first positioning ring 130. The convex surface of the first positioning ring 130 is rectangular, and the rectangular dimension of the convex surface is 0.01 mm smaller than the dimension of the positioning groove 240. There are 1 - 1.5 mm rounded corners on both sides of the convex surface, and the concave surface of the positioning groove 240 is also rectangular with 1 - 1.5 mm rounded corners on both sides, which is beneficial for the sliding fit connection between the first positioning ring 130 and the positioning groove 240.

[0043] In one embodiment of the present disclosure, the intersection surface of the first positioning ring 130 and the outer side of the fluid passage 120 has 1.5 - 2 mm rounded corners, which is beneficial for strengthening the strength of the first positioning ring 130. The intersection surface of the first positioning ring 130 and the connection port 110 is not provided with rounded corners, which is beneficial for the first positioning ring 130 to be squeezed and sealed with the sealing ring 40.

[0044] In one embodiment of the present disclosure, as Figure 6 shown, the second positioning ring 30 can be a C - shaped ring. The second positioning ring 30 has an opening. After the pressing structure 20 presses the second positioning ring 30, the openings on the C - shaped ring are aligned. Thus, the second positioning ring 30 can hold the pipe A tightly to achieve positioning and pressing of the pipe orifice a of the pipe A.

[0045] Optionally, the inner diameter of the C - shaped ring is 0.1 - 0.5 mm larger than the outer diameter of the pipe orifice a, which is beneficial for sleeving the C - shaped ring outside the pipe orifice a.

[0046] In one embodiment of the present disclosure, the inner diameter of the sealing ring 40 is 0.1 - 0.5 mm smaller than the inner diameter of the connection port 110, and the inner diameter of the sealing ring 40 is 0.1 - 0.5 mm smaller than the inner diameter of the pipe orifice a. The sealing ring 40 is sleeved outside the connection port 110 and the pipe orifice a to achieve an interference fit, thereby improving the sealing performance of the sealing ring 40.

[0047] In one embodiment of the present disclosure, the materials of the first semi - circular pressing ring 210 and the second semi - circular pressing ring 220 can be PLA (Polylactic Acid), ABS (Acrylonitrile Butadiene Styrene plastic), nylon, PC (Polycarbonate) / ABS alloy, POM (Polyoxymethylene). The manufacturing method of the first semi - circular pressing ring 210 and the second semi - circular pressing ring 220 can be integral injection molding, with simple manufacturing process, convenient processing and low cost.

[0048] In some embodiments of the present disclosure, as Figure 3 and Figure 4As shown, one end of the first semi-circular pressing ring 210 is hinged to one end of the second semi-circular pressing ring 220, and the other end of the first semi-circular pressing ring 210 and the other end of the second semi-circular pressing ring 220 are connected by a locking member 50. Specifically, a first hinge seat 211 and a first hinge hole 212 are provided on the first semi-circular pressing ring 210, and a second hinge seat 221 and a second hinge hole 222 are provided on the second semi-circular pressing ring 220. The hinge shaft M is inserted into the first hinge hole 212 and the second hinge hole 222 to realize the hinge connection between the first hinge seat 211 and the second hinge seat 221, and further realize the hinge connection between one end of the first semi-circular pressing ring 210 and one end of the second semi-circular pressing ring 220. The hinge connection between one end of the first semi-circular pressing ring 210 and one end of the second semi-circular pressing ring 220 enables the rotatable connection between one end of the first semi-circular pressing ring 210 and one end of the second semi-circular pressing ring 220. Before the connecting assembly is connected to the pipe A, the other ends of the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220 can move in a relatively far-away direction to open the pressing and fixing ring 230. Then, the pressing and fixing ring 230 is sleeved outside the connection port 110 of the connecting assembly and the pipe orifice a of the pipe A. Then, the other ends of the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220 are controlled to move in a relatively close direction to press and fix the connection port 110 of the connecting assembly and the pipe orifice a of the pipe A. Finally, the other end of the first semi-circular pressing ring 210 and the other end of the second semi-circular pressing ring 220 are connected by the locking member 50. The connection method of hinging one end of the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220 and connecting the other end by the locking member 50 can quickly press the first positioning ring 130, the second positioning ring 30, and the sealing ring 40, and further press the connection port of the connecting member 10 and the pipe orifice of the pipe A, improving the installation efficiency of the pipe. Moreover, when the pipe needs to be repaired or replaced, the operation can also be carried out simply and quickly, thus reducing the maintenance difficulty of the pipe.

[0049] In some embodiments of the present disclosure, one end of the first semi-circular pressing ring 210 and one end of the second semi-circular pressing ring 220 are connected by a locking member 50, and the other end of the first semi-circular pressing ring 210 and the other end of the second semi-circular pressing ring 220 are also connected by the locking member 50. When both ends of the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220 are connected by the locking member 50, the first semi-circular pressing ring 210 can be sleeved on one side of the connection port 110 of the connection assembly and the pipe orifice a of the pipe A first, then the second semi-circular pressing ring 220 is sleeved on the other side of the connection port 110 of the connection assembly and the pipe orifice a of the pipe A, then the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220 are pressed, and finally the two ends of the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220 are locked by the locking member 50. The connection method in which both ends of the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220 are connected by the locking member 50 can also press the first positioning ring 130, the second positioning ring 30 and the sealing ring 40 quickly, and then press the connection port of the connecting member 10 and the pipe orifice of the pipe A, improving the installation efficiency of the pipe. Moreover, when the pipe needs to be repaired or replaced, the operation can also be carried out simply and quickly, thus reducing the maintenance difficulty of the pipe.

[0050] In some embodiments of the present disclosure, as Figure 5 shown, a rib 410 is provided on the inner side of the sealing ring 40. The cross-sectional shape of the rib 410 is rectangular. There is a gap between the connection port 110 and the pipe orifice a of the pipe A. The rib 410 is placed in the gap and tightly abuts against the ends of the connection port 110 and the pipe orifice a. The rib 410 provided on the inner side of the sealing ring 40 is placed in the gap between the connection port 110 and the pipe orifice a and tightly abuts against the ends of the connection port 110 and the pipe orifice a, which can separate the connection port 110 and the pipe orifice a, reduce noise, achieve flexible docking, and can also further improve the connection sealing performance and safety of the connection port 110 and the pipe orifice a. The rib 410 is also used to compensate for the irregularity of the local connection of the connection port 110 and the pipe orifice a, making the connection between the connection port 110 and the pipe orifice a more stable. In addition, the rib 410 can also be used as a limiting structure to reduce the probability of the sealing ring 40 sliding along the extending direction of the connection port 110 and the pipe orifice a, improving the stability of the pipe connection.

[0051] Optionally, the width of the rib 410 is 3-5 mm, and the inner diameter of the rib 410 is 2-3 mm smaller than the outer diameters of the connection port 110 and the pipe orifice a.

[0052] In some embodiments of the present disclosure, as Figure 1 、 Figure 5 and Figure 6As shown, on one side of the sealing ring 40 close to the second positioning ring 30, a first conical surface 420 is provided, and the cone angle of the first conical surface 420 is 40° - 48°; on one side of the second positioning ring 30 close to the sealing ring 40, a second conical surface 310 that closely abuts against the first conical surface 420 is provided, and the cone angle of the second conical surface 310 is 40° - 48°.

[0053] The axial angle between the hypotenuse of the upper first conical surface 420 of the sealing ring 40 is 20° - 24°, and the axial angle between the hypotenuse of the lower first conical surface 420 is also 20° - 24°. Therefore, the cone angle of the first conical surface 420 is the angle between the extension lines of the hypotenuses of the upper first conical surface 420 and the lower first conical surface 420, which is twice the axial angle of one side hypotenuse, that is, 40° - 48°. Similarly, it can be obtained that the cone angle of the second conical surface 310 provided on the second positioning ring 30 is 40° - 48°. By providing the first conical surface 420 on one side of the sealing ring 40 close to the second positioning ring 30, and providing the second conical surface 310 on one side of the second positioning ring 30 close to the sealing ring 40, when the pressing fixing ring 230 presses the sealing ring 40 and the second positioning ring 30, the second conical surface 310 on the second positioning ring 30 presses the first conical surface 420 on the sealing ring 40, thereby improving the sealing performance of the sealing ring 40.

[0054] In some embodiments of the present disclosure, as Figure 1 、 Figure 2 and Figure 5 shown, on one side of the sealing ring 40 close to the first positioning ring 130, a third conical surface 430 is provided, and the cone angle of the third conical surface 430 is 100° - 110°; in the first groove clamping portion 250, a first pressing surface 251 that cooperates with the third conical surface 430 is provided, the first pressing surface 251 is a conical surface, and the cone angle of the first pressing surface 251 is 100° - 110°.

[0055] The axial angle between the hypotenuse of the upper third conical surface 430 of the sealing ring 40 is 50° - 55°, and the axial angle between the hypotenuse of the lower third conical surface 430 is also 50° - 55°. Therefore, the cone angle of the third conical surface 430 is the angle between the extension lines of the hypotenuses of the upper third conical surface 430 and the lower third conical surface 430, which is twice the axial angle of one side hypotenuse, that is, 100° - 110°. Similarly, it can be obtained that the cone angle of the first pressing surface 251 is 100° - 110°. By providing the third conical surface 430 on the sealing ring 40 and providing the first pressing surface 251 in the first groove clamping portion 250, when the pressing fixing ring 230 presses the sealing ring 40, the first pressing surface 251 in the first groove clamping portion 250 presses the third conical surface 430 on the sealing ring 40, thereby pressing the sealing ring 40, and thereby improving the sealing performance of the sealing ring 40.

[0056] In some embodiments of the present disclosure, as Figure 1 , Figure 2 , Figure 6 and Figure 7 shown, on the side of the second positioning ring 30 away from the sealing ring 40, a fourth conical surface 320 is provided, and the cone angle of the fourth conical surface 320 is 150° - 160°; in the second groove clamping portion 260, a second pressing surface 261 that cooperates with the fourth conical surface 320 is provided, the second pressing surface 261 is a conical surface, and the cone angle of the second pressing surface 261 is 150° - 160°; on the side of the second positioning ring 30 away from the pipe opening a of the pipe A, a fifth conical surface 330 is provided, and the cone angle of the fifth conical surface 330 is 6° - 12°; in the second groove clamping portion 260, a third pressing surface 262 that cooperates with the fifth conical surface 330 is provided, the third pressing surface 262 is a conical surface, and the cone angle of the third pressing surface 262 is 6° - 12°.

[0057] The axial angle of the hypotenuse of the upper fourth conical surface 320 of the second positioning ring 30 is 75° - 80°, and the axial angle of the hypotenuse of the lower fourth conical surface 320 is also 75° - 80°. Therefore, the cone angle of the fourth conical surface 320 is the included angle between the extension lines of the hypotenuses of the upper fourth conical surface 320 and the lower fourth conical surface 320, that is, twice the axial angle of one side hypotenuse, which is 150° - 160°. Similarly, it can be obtained that the cone angle of the second pressing surface 261 is 150° - 160°. The axial angle of the hypotenuse of the upper fifth conical surface 330 of the second positioning ring 30 is 3° - 6°, and the axial angle of the hypotenuse of the lower fifth conical surface 330 is also 3° - 6°. Therefore, the fifth conical surface 330 is the included angle between the extension lines of the hypotenuses of the upper fifth conical surface 330 and the lower fifth conical surface 330, that is, twice the axial angle of one side hypotenuse, which is 6° - 12°. Similarly, it can be obtained that the cone angle of the third pressing surface 262 is 6° - 12°. By providing the fourth conical surface 320 and the fifth conical surface 330 on the second positioning ring 30, and correspondingly providing the second pressing surface 261 and the third pressing surface 262 in the second groove clamping portion 260, when the pressing fixing ring 230 presses the second positioning ring 30, the second pressing surface 261 in the second groove clamping portion 260 presses the fourth conical surface 320 on the second positioning ring 30, and the third pressing surface 262 in the second groove clamping portion 260 presses the fifth conical surface 330 on the second positioning ring 30, thereby pressing the second positioning ring 30, enabling the second positioning ring 30 to hold the pipe opening tightly, and also enabling the second positioning ring 30 to press towards the direction of the sealing ring 30, thereby improving the sealing performance of the sealing ring 40.

[0058] In some embodiments of the present disclosure, as Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the fourth conical surface 320 and the fifth conical surface 330 intersect, and a fillet with a size of 1.5 - 2.0 mm is provided at the intersection position. Correspondingly, the second pressing surface 261 and the third pressing surface 262 intersect, and a fillet with a size of 1.5 - 2.0 mm is provided at the intersection position, which is beneficial to realizing the sliding fit between the second groove clamping portion 260 and the second positioning ring 30, and further realizing the rapid pressing of the pressing fixing ring 230.

[0059] In some embodiments of the present disclosure, as Figure 1 , Figure 2 , Figure 5 shown, a part of the side of the sealing ring 40 close to the first positioning ring 130 is a flat surface, namely the first flat surface 440.

The third conical surface 430 is in close contact with the first pressing surface 251 in the first groove clamping portion 250. The first flat surface 440 intersects with the third conical surface 430. Thus, the side of the sealing ring 40 close to the first positioning ring 130 is in close contact with both the first positioning ring 130 and the first groove clamping portion 250 at the same time. When pressing the pressing fixing ring 230, the first positioning ring 130 and the first pressing surface 251 press towards the sealing ring 40 simultaneously, avoiding the axial displacement of the sealing ring 40 and improving the sealing performance of the sealing ring 40.

[0060] In some embodiments of the present disclosure, as Figure 1 , Figure 5 , Figure 6 and Figure 7 shown, a part of the side of the sealing ring 40 close to the second positioning ring 30 is a flat surface, namely the second flat surface 450. A corresponding third flat surface 340 is provided on the side of the second positioning ring 30 close to the sealing ring 40. The second flat surface 450 is in close contact with the third flat surface 340. Moreover, the first conical surface 420 in the sealing ring 40 intersects with the second flat surface 450, and the second conical surface 310 in the second positioning ring 30 intersects with the third flat surface 340. In this way, when pressing the pressing fixing ring 230, the second conical surface 310 and the third flat surface 340 in the second positioning ring 30 press towards the first conical surface 420 and the second flat surface 450 in the sealing ring 40 simultaneously, avoiding the axial displacement of the sealing ring 40 and improving the sealing performance of the sealing ring 40.

[0061] In some embodiments of the present disclosure, as Figure 1 , Figure 2 , Figure 5As shown, on the side of the sealing ring 40 away from the connection port 110 and the pipe orifice a, there is a fourth flat surface 460. One side of the fourth flat surface 460 of the sealing ring 40 intersects with the first conical surface 420, and the other side intersects with the third conical surface 430. In the first groove clamping portion 250, there is a fourth pressing surface 252 that cooperates with the fourth flat surface 460. One side of the fourth pressing surface 252 intersects with the first pressing surface 251, and the diameter of the fourth pressing surface 252 is 0.5 - 0.7 mm larger than the diameter of the fourth flat surface 460. When pressing the pressing and fixing ring 230, while ensuring the sealed connection of the sealing ring 40, a deformation space is reserved for the sealing ring 40 to ensure the docking of the sealing ring 40 with the first groove clamping portion 250.

[0062] In some embodiments of the present disclosure, as Figure 7 shown, on the side of the second positioning ring 30 close to the pipe orifice a of the pipe A, there is an anti-slip tooth section 350. The provision of the anti-slip tooth section 350 is beneficial for enabling the second positioning ring 30 to hold the pipe orifice a tightly when the pressing and fixing ring 230 presses the second positioning ring 30, preventing axial displacement between the second positioning ring 30 and the pipe orifice a.

[0063] In some embodiments of the present disclosure, as Figure 3 and Figure 4 shown, the locking member 50 includes a connecting rod 510. One end of the connecting rod 510 is hinged to the first semi-circular pressing ring 210.

The connecting rod 510 is snap-fitted with the pressing groove 223. The locking member 50 further includes a pressing handle 520 hingedly connected to the other end of the connecting rod 510.

[0064] When connecting the pipes, open the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220, place the connector 10 and the pipe A after sleeving the sealing ring 40 and the second positioning ring 30 into the accommodating cavity formed by the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220. Then, make the positioning groove 240, the first groove clamping portion 250, and the second groove clamping portion 260 respectively dock with the first positioning ring 130, the sealing ring 40, and the second positioning ring 30. Then, press the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220, and rotate the pressing handle 520 clockwise to drive the connecting rod 510 to rotate towards the second semi-circular pressing ring 220, press the connecting rod 510 into the pressing groove 223, and make the connecting rod 510 and the pressing groove 223 snap-fitted. Finally, rotate the pressing handle 520 counterclockwise to make the pressing handle 520 press the pressing and fixing ring 230.

[0065] In some embodiments of the present disclosure, as Figure 3 、 Figure 4 and Figure 9As shown, first semi-circular pressing rings 210 and second semi-circular pressing rings 220 are both provided with first bosses 213 (224); one end of a connecting rod 510 is hinged to the first boss 213 on the first semi-circular pressing ring 210, and the locking member 50 further includes a pressing groove 223 provided on the first boss 224 on the second semi-circular pressing ring 220 and matching the connecting rod 510, and the connecting rod 510 is snap-fitted with the pressing groove 223; the locking member 50 further includes a pressing handle 520 hinged to the other end of the connecting rod 510.

[0066] Optionally, a third hinge hole 214 is provided on the first boss 213, a fourth hinge hole 511 and a fifth hinge hole 512 are provided on the connecting rod 510, and a sixth hinge hole 521 is provided at one end of the pressing handle 520. A hinge shaft N is inserted into the third hinge hole 214 and the fourth hinge hole 511 to hinge and connect one end of the first boss 213 and the connecting rod 510, and a hinge shaft P is inserted into the fifth hinge hole 512 and the sixth hinge hole 521 to hinge and connect the other end of the connecting rod 510 and one end of the pressing handle 520.

[0067] When connecting pipes, open the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220, place the connector 10 and the pipe A after sleeving the sealing ring 40 and the second positioning ring 30 into the accommodating cavity formed by the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220, then align the positioning groove 240, the first groove clamping part 250 and the second groove clamping part 260 with the first positioning ring 130, the sealing ring 40 and the second positioning ring 30 respectively, and then press the first semi-circular pressing ring 210 and the second semi-circular pressing ring 220, and rotate the pressing handle 520 clockwise with the hinge shaft N and the hinge shaft P as the centers to drive the connecting rod 510 to rotate towards the second semi-circular pressing ring 220, press the connecting rod 510 into the pressing groove 223 on the first boss 224, make the connecting rod 510 and the pressing groove 223 snap-fitted, and finally rotate the pressing handle 520 counterclockwise with the hinge shaft P as the center to make the pressing handle 520 press the pressing and fixing ring 230, realizing quick pressing and locking without rebounding.

[0068] When the pipe needs to be repaired or replaced, rotate the pressing handle 520 clockwise with the hinge shaft P as the center to make the pressing handle 520 loosen the pressing and fixing ring 230, then rotate the pressing handle 520 counterclockwise with the hinge shaft N and the hinge shaft P as the centers to drive the connecting rod 510 to rotate towards the first semi-circular pressing ring 210, and further move the connecting rod 510 out of the pressing groove 223 on the first boss 224, thereby unlocking the pressing and fixing ring 230 for the repair and replacement of the pipe.

[0069] In some embodiments of the present disclosure, such as Figure 8As shown, the pressing handle 520 includes an eccentric cam 522 and a flat-section pressing plate 523.
