Abstract

The invention relates to the technical field of suspension clamps, in particular to a suspension clamp fixing structure and a fixing method.The suspension clamp fixing structure comprises an upper pressing plate, a lower pressing plate, an end locking mechanism and two U-shaped hanging rings, and avoiding through holes allowing the two U-shaped hanging rings to be inserted therein are formed in a clamp body. Even if the nut is loosened or the cable is shrunk, when the cable pulls the lower pressing plate to horizontally move leftwards or rightwards through extrusion friction force provided by the cable, the lower pressing plate is jacked upwards to extrude the cable through the action of the arc-shaped convex block. And in order to have higher extrusion force, when a lower pressing plate moves, a downward pushing mechanism is pushed to move through a first contact plate, so that a U-shaped hanging ring downwards pulls an upper pressing plate, the upper pressing plate downwards extrudes the top of the cable, and through co-extrusion of the upper pressing plate and the lower pressing plate, higher extrusion force can be achieved.

Description

Technical Field

[0001] The invention relates to the technical field of suspension wire clamps, and in particular to a suspension wire clamp fixing structure and a fixing method. Background Art

[0002] When replacing or installing the suspension clamp at high altitude, there are many accessories on the suspension clamp and it is not easy to operate. This means that during installation, special attention should be paid to prevent the accessories from falling from high altitude. If they fall, workers need to take new suspension clamps for reinstallation. If there are none, they need to go down to pick them up, which is troublesome. In addition, when the cable and the suspension clamp are used for a long time, the cable and the upper pressure plate and the suspension clamp body will become loose. This looseness will cause the cable to slide to the left or right along the suspension clamp body, making the weight on the left and right uneven, and eventually there is a risk of the cable and the suspension clamp separating and falling. There are two main factors that cause the cable and the suspension clamp to loosen. One is that the cable shakes the suspension clamp due to the wind, which eventually causes the nut on the suspension clamp to loosen. The other is that the rubber on the cable surface expands and contracts with the change of temperature.

[0003] Therefore, in order to solve the above problems, it is necessary to design a suspension wire clamp fixing structure and fixing method, which can keep the cable fixed during long-term use even if the nut is loose or the cable shrinks. Under this premise, it is also necessary to be more convenient when installed at high altitude. Summary of the invention

[0004] In view of the above-mentioned technical deficiencies, the object of the present invention is to provide a suspension wire clamp fixing structure and fixing method, which can keep the cable fixed during long-term use even if the nut is loose or the cable shrinks, and under this premise, it is also necessary to be more convenient when installed at high altitude.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical scheme: the present invention provides a suspension wire clamp fixing structure, comprising an upper pressing plate, a lower pressing plate, an end locking mechanism and two U-shaped hanging rings. The wire clamp body is provided with avoidance through holes for inserting the two U-shaped hanging rings respectively. The end locking mechanism is located below the wire clamp body. The end locking mechanism is used to lock the ends of the two U-shaped hanging rings. The cable contacts the bottom of the lower pressing plate, and the upper pressing plate contacts the top of the cable. The upper pressing plate is clamped on the inner edge of the U-shaped hanging ring. When the cable is fixed, a triangular bevel groove is provided on the outer edge of each U-shaped hanging ring. The bottom of the triangular bevel groove is a plane structure. A plurality of elastic positioning mechanisms are fixedly provided on the outer edge of the wire clamp body. The elastic positioning mechanism is used to resist the bottom of the triangular bevel groove when the U-shaped hanging ring moves upward. A plurality of arc-shaped protrusions are provided at the bottom of the lower pressing plate, and a plurality of arc-shaped grooves for the arc-shaped protrusions to be clamped are provided at the bottom of the inner edge of the wire clamp body.

[0006] Preferably, a tensioning mechanism is fixedly provided at the bottom of the lower pressure plate, and the tensioning mechanism includes two connecting columns and two contact plates. The tops of the two connecting columns are fixedly connected to the lower pressure plate, and the bottoms of the connecting columns pass through the wire clamp body. The wire clamp body is provided with avoidance holes for the connecting columns to pass through. Contact plate 1 is fixedly installed at the bottom of the connecting columns, and the outer edge projection of contact plate 1 is larger than the diameter of the avoidance hole, and a gap is left between contact plate 1 and the bottom of the wire clamp body, and the gap is used for the arc-shaped protrusion to slide upward along the arc-shaped groove to leave a displacement.

[0007] Preferably, the end locking mechanism includes a contact plate 2 and four upper locking nuts. A sliding sleeve is fixedly provided on the contact plate 2, and the sliding sleeve is inserted in the avoidance through hole so that the contact plate 2 can slide vertically. The inner diameter of the sliding sleeve is larger than the outer diameter of the connecting column. When the upper locking nut is not in contact with the contact plate 2, the contact plate 2 contacts the top of the contact plate 1 through gravity. An avoidance hole is provided on the end locking mechanism for the end of the U-shaped hanging ring to pass through. The end of the U-shaped hanging ring is a threaded structure. The four upper locking nuts are respectively engaged with the ends of the two U-shaped hanging rings, and the top of the upper locking nut is in conflict with the bottom of the contact plate 2.

[0008] Preferably, it also includes two pushing-down mechanisms, which are fixedly mounted on the wire clamp body and are symmetrically arranged, one end of each pushing-down mechanism is transmission connected to a contact plate, and the other end of the pushing-down mechanism is transmission connected to a U-shaped hanging ring. When the contact plate moves upward at an angle, the contact plate pushes the U-shaped hanging ring to move vertically downward through the power transmission of the pushing-down mechanism.

[0009] Preferably, the push-down mechanism includes a rotating plate, a rotating seat, a transmission column and a lower locking nut. The rotating seat is fixedly installed on the wire clamp body, the middle part of the rotating plate is rotatably connected to the rotating seat, and rings are provided at both ends of the transmission column. The rings are sleeved on the outer edge of the U-shaped hanging ring, the top of the ring is in contact with the bottom of the upper locking nut, the bottom of the ring is in contact with the top of the lower locking nut, one end of the rotating plate is in contact with the contact plate, and the other end of the rotating plate is in contact with the transmission column.

[0010] Preferably, each elastic positioning mechanism includes a bent plate and a torsion spring. A rotating seat for rotating the bent plate is fixedly provided on the wire clamp body. The top of the bent plate is rotatably connected to the rotating seat. The torsion spring is fixedly installed on the rotating seat. The torsion spring is used to apply an elastic force to the bottom of the bent plate toward the wire clamp body. The end of the bent plate contacts the outer edge of the U-shaped hanging ring.

[0011] Preferably, two clamping plates are fixedly provided on the top of the upper pressing plate, the inner sides of the two clamping plates are fitted with the outer sides of the two U-shaped hanging rings, and two end feet are provided at the bottom of each upper pressing plate, and the outer edges of the two end feet are in contact with the inner edges of the U-shaped hanging rings.

[0012] A method for fixing a suspension wire clamp fixing structure, characterized by comprising the following steps: Step 1: Insert the two U-shaped hanging rings into the wire clamp body along the avoidance through-holes. The ends of the U-shaped hanging rings will push the bent plate to rotate outwards. The ends of the U-shaped hanging rings will pass through the avoidance holes of the contact plate 2. When the triangular bevel groove is flush with the bottom of the bent plate, the torsion spring will push the bent plate into the triangular bevel groove. Step 2: Engage and install the upper locking nut on the U-shaped hanging ring, and push the top of the contact plate 2 upward to contact the bottom of the wire clamp body; Step 3: Sleeve the collar connected to the transmission column onto the end of the U-shaped hanging ring, and then engage it on the U-shaped hanging ring through the lower locking nut, so that the top of the lower locking nut contacts the bottom of the collar; Step 4: When the cable is pulled, the cable pulls the lower pressing plate horizontally through friction, and the arc-shaped protrusion slides along the arc-shaped groove; Step 5: The lower pressure plate pulls the contact plate 1 to move upward through the connecting column. The contact plate 1 pushes the rotating plate to rotate along the rotating seat. The bottom of the rotating plate pulls the transmission column downward. The transmission column pulls the U-shaped hanging ring downward. The U-shaped hanging ring pushes the upper pressure plate to squeeze the top of the cable.

[0013] The beneficial effect of the present invention is that the suspension wire clamp fixing structure and fixing method can, when used for a long time, even if the nut is loose or the cable shrinks, the extrusion friction provided by the cable can make the cable pull the lower pressure plate to move horizontally to the left or right, and the lower pressure plate can be pushed up to squeeze the cable through the arc-shaped protrusion of the lower pressure plate. In order to have a stronger extrusion force, when the lower pressure plate moves, the contact plate will push the push-down mechanism to move, so that the U-shaped hanging ring pulls the upper pressure plate downward, so that the upper pressure plate squeezes the top of the cable downward, and through the joint extrusion of the upper and lower pressure plates, there can be a stronger extrusion force.

[0014] And through the connection between the end locking mechanism and the lower pressure plate, the end locking mechanism and the lower pressure plate are locked on the wire clamp body, reducing the parts that need to be assembled, and when the U-shaped hanging ring is inserted downward into the wire clamp body, the U-shaped hanging ring is clamped and locked through the elastic positioning mechanism to prevent the U-shaped hanging ring from separating upward from the wire clamp body. Finally, only the upper locking nut, transmission column and lower locking nut that have been inserted into the cable need to be blocked and assembled, which is more convenient when installed at high altitude. And the above-mentioned convenient assembly structures will not affect the subsequent automatic clamping of the cable by the upper and lower pressure plates. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment: The present invention provides a suspension wire clamp fixing structure, comprising an upper pressure plate 3, a lower pressure plate 4, an end locking mechanism 7 and two U-shaped hanging rings 2. The wire clamp body 1 is provided with avoidance through holes 1c for inserting the two U-shaped hanging rings 2 respectively. The end locking mechanism 7 is located below the wire clamp body 1. The end locking mechanism 7 is used to lock the ends of the two U-shaped hanging rings 2. The cable 10 contacts the bottom of the lower pressure plate 4, and the upper pressure plate 3 contacts the top of the cable 10. The upper pressure plate 3 is clamped on the inner edge of the U-shaped hanging ring 2. When the cable 10 is fixed, the U-shaped hanging ring 2 is inserted into the avoidance through hole 1c and locked with the end locking mechanism 7. Then, the cable 10 is squeezed by the upper pressure plate 3 and the lower pressure plate 4 to fix the cable 10. In order to facilitate the fixing and installation of parts during high-altitude operations, a triangular bevel groove 2a is provided on the outer edge of each U-shaped hanging ring 2, and the bottom of the triangular bevel groove 2a is a plane structure. A plurality of elastic positioning mechanisms 6 are fixedly arranged on the outer edge of the wire clamp body 1. The elastic positioning mechanism 6 is used to resist the bottom of the triangular bevel groove 2a when the U-shaped hanging ring 2 moves upward, so that when the U-shaped hanging ring 2 is fully inserted into the avoidance through hole 1c, the triangular bevel groove 2a will pass through the end of the elastic positioning mechanism 6. Since the end of the elastic positioning mechanism 6 contacts the inclined surface of the triangular bevel groove 2a at this time, the elastic positioning mechanism 6 will not block the U-shaped hanging ring 2. When the U-shaped hanging ring 2 is pulled upward, the end of the elastic positioning mechanism 6 will contact the plane of the triangular bevel groove 2a, so that the elastic positioning mechanism 6 blocks the U-shaped hanging ring 2, ensuring that the U-shaped hanging ring 2 can only be inserted downward, but cannot be pulled upward, which can facilitate the fixing and installation of parts during high-altitude operations. When the U-shaped hanging ring 2 is connected to the elastic positioning mechanism 6, although the U-shaped hanging ring 2 still has some space for upward movement (the space is generated due to the gap between the triangular bevel groove 2a and the end of the elastic positioning mechanism 6), when the U-shaped hanging ring 2 moves upward, the upper pressing plate 3 will not fall off from the U-shaped hanging ring 2. In order to increase the clamping of the cable 10 when the cable 10 is pulled, a plurality of arc-shaped protrusions 4a are provided at the bottom of the lower pressing plate 4, and a plurality of arc-shaped grooves 1a for the arc-shaped protrusions 4a to be inserted into the bottom of the inner edge of the wire clamp body 1 are provided. Since the pressure of the cable 10 mainly acts on the lower pressing plate 4, when the cable 10 moves horizontally, it will drive the lower pressing plate 4 to move horizontally through friction, so that the lower pressing plate 4 squeezes the cable 10 upward, which can increase the clamping of the cable 10. Even if the nut is loose or the cable shrinks, the cable 10 can be fixed for a long time. And because the arc-shaped protrusion 4a is pressed into the arc-shaped groove 1a when the accessories are installed, automatic positioning can be performed.

[0026] Among them, since the lower pressure plate 4 in the above solution is a plate and has no connection with the wire clamp body 1, the lower pressure plate 4 is easy to slip out of the wire clamp body 1 during high-altitude operation. In order to prevent the lower pressure plate 4 from slipping, for this reason, Figure 3 As shown, the bottom of the lower pressing plate 4 is fixedly provided with a tensioning mechanism 9, which includes two connecting columns 9a and two contact plates 9b. The tops of the two connecting columns 9a are fixedly connected to the lower pressing plate 4, and the bottom of the connecting column 9a passes through the wire clamp body 1. The wire clamp body 1 is provided with an avoidance hole 1b for the connecting column 9a to pass through, wherein the diameter of the avoidance hole 1b is larger than the diameter of the connecting column 9a, and the avoidance hole 1b is used for the subsequent insertion of the sliding sleeve 7a1. The contact plate 9b is fixedly installed at the bottom of the connecting column 9a, and the outer edge projection of the contact plate 9b is larger than the diameter of the avoidance hole 1b, and there is a gap between the contact plate 9b and the bottom of the wire clamp body 1, and the gap is used for the arc-shaped protrusion 4a to slide upward along the arc-shaped groove 1a with a displacement. Through the locking effect of the connecting column 9a and the contact plate 9b on the lower pressing plate 4, a connection is established between the lower pressing plate 4 and the wire clamp body 1, ensuring that the lower pressing plate 4 will not be separated from the wire clamp body 1.

[0027] Among them, since the lower pressure plate 4 in the above solution is a plate and has no connection with the wire clamp body 1, the lower pressure plate 4 is easy to slip out of the wire clamp body 1 during high-altitude operation. In order to prevent the lower pressure plate 4 from slipping, for this reason, Figure 3 As shown, the bottom of the lower pressing plate 4 is fixedly provided with a tensioning mechanism 9, which includes two connecting columns 9a and two contact plates 9b. The tops of the two connecting columns 9a are fixedly connected to the lower pressing plate 4, and the bottom of the connecting column 9a passes through the wire clamp body 1. The wire clamp body 1 is provided with an avoidance hole 1b for the connecting column 9a to pass through, wherein the diameter of the avoidance hole 1b is larger than the diameter of the connecting column 9a, and the avoidance hole 1b is used for the subsequent insertion of the sliding sleeve 7a1. The contact plate 9b is fixedly installed at the bottom of the connecting column 9a, and the outer edge projection of the contact plate 9b is larger than the diameter of the avoidance hole 1b, and there is a gap between the contact plate 9b and the bottom of the wire clamp body 1, and the gap is used for the arc-shaped protrusion 4a to slide upward along the arc-shaped groove 1a with a displacement. Through the locking effect of the connecting column 9a and the contact plate 9b on the lower pressing plate 4, a connection is established between the lower pressing plate 4 and the wire clamp body 1, ensuring that the lower pressing plate 4 will not be separated from the wire clamp body 1.

[0028] If the cable 10 is clamped only by pushing the lower pressing plate 4 upward, the moving distance is small, and there is a probability that the cable 10 pushed upward by the lower pressing plate 4 fails to be squeezed and collided with the upper pressing plate 3, resulting in the cable 10 still being able to slide horizontally. Figure 4As shown, two push-down mechanisms 8 are also included. The two push-down mechanisms 8 are fixedly mounted on the wire clamp body 1, and the two push-down mechanisms 8 are symmetrically arranged. One end of each push-down mechanism 8 is transmission-connected with the contact plate 9b, and the other end of the push-down mechanism 8 is transmission-connected with the U-shaped hanging ring 2. When the contact plate 9b moves upward at an angle, the contact plate 9b pushes the U-shaped hanging ring 2 to move vertically downward through the power transmission of the push-down mechanism 8. When the lower pressing plate 4 is pulled by the cable 10, the contact plate 9b will be driven to move upward at an angle, and the U-shaped hanging ring 2 will be pulled down through the transmission of the push-down mechanism 8, so that the U-shaped hanging ring 2 pushes the upper pressing plate 3 downward, so that the upper pressing plate 3 can squeeze the top of the cable 10, and through the upper and lower squeezing of the upper pressing plate 3 and the lower pressing plate 4, the range of clamping movement can be increased to ensure that the cable 10 can be clamped.

[0029] And no matter the cable 10 pulls the lower pressing plate 4 to the left or right, it can drive the lower pressing plate 4 to move upward to the left or to the right. And because the push-down mechanism 8 is symmetrically arranged, no matter which direction the push-down mechanism 8 moves, the corresponding push-down mechanism 8 is driven to ensure that the upper pressing plate 3 can be pressed downward.

[0030] In order to realize the conversion of the upward tilting power of the contact plate 9b into the power for the U-shaped hanging ring 2 to pull downward, for this purpose, Figure 4 As shown, the push-down mechanism 8 includes a rotating plate 8a, a rotating seat 8b, a transmission column 8c and a lower locking nut 8d. The rotating seat 8b is fixedly installed on the wire clamp body 1, the middle part of the rotating plate 8a is rotatably connected to the rotating seat 8b, and rings are provided at both ends of the transmission column 8c. The rings are sleeved on the outer edge of the U-shaped hanging ring 2, the top of the ring is in contact with the bottom of the upper locking nut 7b, and the bottom of the ring is in contact with the top of the lower locking nut 8d. The transmission column 8c is locked on the U-shaped hanging ring 2 through the action of the upper locking nut 7b and the lower locking nut 8d, one end of the rotating plate 8a is in contact with the contact plate 9b, and the other end of the rotating plate 8a is in contact with the transmission column 8c. When the contact plate 9b is tilted and pushed upward, the contact plate 9b will push the rotating plate 8a to rotate along the rotating seat 8b, that is, the rotating plate 8a pushes the transmission column 8c downward, and the transmission column 8c can pull the U-shaped hanging ring 2 to move downward, so that the U-shaped hanging ring 2 pulls the upper pressure plate 3 to squeeze the cable 10. It can be seen that the middle part of the rotating plate 8a is short near the contact plate 9b, so that the contact plate 9b moves slightly, which can drive the transmission column 8c to move downward to a large extent. And through the upper locking nut 7b and the lower locking nut 8d, the probability of the U-shaped hanging ring 2 loosening is reduced, and when it is loose, the lower locking nut 8d is loosened first, so that the U-shaped hanging ring 2 can still be fixed in the original position. After the lower locking nut 8d is loosened, the rotating plate 8a can still contact the transmission column 8c.

[0031] In order to achieve this, when the U-shaped hanging ring 2 is pulled upward, the end of the elastic positioning mechanism 6 will contact the plane of the triangular bevel groove 2a, so that the elastic positioning mechanism 6 blocks the U-shaped hanging ring 2, but does not block the U-shaped hanging ring 2 during the downward insertion process. Figure 1 and Figure 6 As shown, each elastic positioning mechanism 6 includes a bent plate 6a and a torsion spring 6b. A rotating seat for the bent plate 6a to rotate is fixedly provided on the wire clamp body 1. The top of the bent plate 6a is rotatably connected to the rotating seat. The torsion spring 6b is fixedly installed on the rotating seat. The torsion spring 6b is used to apply an elastic force to the bottom of the bent plate 6a toward the wire clamp body 1. The end of the bent plate 6a contacts the outer edge of the U-shaped hanging ring 2. When the U-shaped hanging ring 2 is inserted from top to bottom into the avoidance through hole 1c, the end of the bent plate 6a can be inserted into the triangular bevel groove 2a, and after the clamping, the U-shaped hanging ring 2 will not be able to be pulled upward. Figure 6 As shown, when the diameter of the cable 10 becomes smaller, the downward movement of the U-shaped hanging ring 2 will increase, and the end of the bent plate 6a originally stuck in the triangular inclined groove 2a can slide out without causing any obstruction to the U-shaped hanging ring 2, so that the suspension wire clamp fixing structure can be applied to cables 10 of various diameters.

[0032] In order to realize the clamping connection between the upper pressing plate 3 and the U-shaped hanging ring 2, Figure 6 As shown, two clamping plates 3a are fixedly provided on the top of the upper pressing plate 3, and the inner sides of the two clamping plates 3a are fitted with the outer sides of the two U-shaped hanging rings 2. The clamping plates 3a are used to limit the displacement of the upper pressing plate 3 in the length direction. Two end feet 3b are provided at the bottom of each upper pressing plate 3, and the outer edges of the two end feet 3b are in contact with the inner edges of the U-shaped hanging ring 2. The width direction of the upper pressing plate 3 is limited by the action of the two end feet 3b to prevent the upper pressing plate 3 from shifting left and right. By limiting the length and width directions of the upper pressing plate 3, the clamping connection between the upper pressing plate 3 and the U-shaped hanging ring 2 can be achieved. And from Figure 6 It can be seen from the figure that when the diameter of the cable 10 becomes smaller, when the upper pressing plate 3 descends, the end of the end foot 3b will not touch the wire clamp body 1.

[0033] A method for fixing a suspension wire clamp fixing structure comprises the following steps: Step 1: Insert two U-shaped hanging rings 2 into the wire clamp body 1 along the avoidance through hole 1c. The ends of the U-shaped hanging rings 2 will push the bent plate 6a to rotate outward, and the ends of the U-shaped hanging rings 2 will pass through the avoidance hole of the contact plate 2 7a. When the triangular bevel groove 2a is flush with the bottom of the bent plate 6a, the torsion spring 6b will push the bent plate 6a to insert into the triangular bevel groove 2a. Step 2: Engage and install the upper locking nut 7b on the U-shaped hanging ring 2, and the upper locking nut 7b pushes the top of the contact plate 7a upward to contact the bottom of the wire clamp body 1; Step 3: Sleeve the collar connected to the transmission column 8c onto the end of the U-shaped hanging ring 2, and then engage it on the U-shaped hanging ring 2 through the lower locking nut 8d, so that the top of the lower locking nut 8d abuts against the bottom of the collar; Step 4: When the cable 10 is pulled, the cable 10 pulls the lower pressing plate 4 horizontally by friction force, and the arc-shaped protrusion 4a slides along the arc-shaped groove 1a; Step 5: The lower pressure plate 4 pulls the contact plate 9b to move upward through the connecting column 9a, and the contact plate 9b pushes the rotating plate 8a to rotate along the rotating seat 8b. The bottom of the rotating plate 8a pulls the transmission column 8c downward, and the transmission column 8c pulls the U-shaped hanging ring 2 to move downward, and the U-shaped hanging ring 2 pushes the upper pressure plate 3 to squeeze the top of the cable 10.

[0034] The suspension wire clamp fixing structure and fixing method can, when used for a long time, even if the nut is loose or the cable shrinks, the extrusion friction provided by the cable 10 can make the cable 10 pull the lower pressing plate 4 to move horizontally to the left or right, and the lower pressing plate 4 can be pushed upward to squeeze the cable 10 through the arc-shaped protrusion 4a of the lower pressing plate 4. In order to have a stronger extrusion force, when the lower pressing plate 4 moves, the contact plate 9b will push the push-down mechanism 8 to move, so that the U-shaped hanging ring 2 pulls the upper pressing plate 3 downward, so that the upper pressing plate 3 squeezes the top of the cable 10 downward, and through the joint extrusion of the upper pressing plate 3 and the lower pressing plate 4, a stronger extrusion force can be achieved.

[0035] And through the connection between the end locking mechanism 7 and the lower pressing plate 4, the end locking mechanism 7 and the lower pressing plate 4 are locked on the wire clamp body 1, reducing the parts that need to be assembled, and when the U-shaped hanging ring 2 is inserted downward into the wire clamp body 1, the U-shaped hanging ring 2 is clamped and locked by the elastic positioning mechanism 6 to prevent the U-shaped hanging ring 2 from separating upward from the wire clamp body 1. Finally, only the upper locking nut 7b, the transmission column 8c and the lower locking nut 8d that have been inserted into the cable 10 need to be blocked and assembled, that is, it is more convenient when installed at high altitude. And the above-mentioned convenient assembly structures will not affect the subsequent automatic clamping of the cable 10 by the upper pressing plate 3 and the lower pressing plate 4.

[0036] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
