Description

Technical Field

[0001] The invention relates to the technical field of power tools, and in particular to an anti-loosening type tension wire clamp. Background Art

[0002] A tension clamp is a clamp used to fix wires to withstand the tension of the wires and hang the wires on tension strings or pole towers.

[0003] An existing anti-loosening type tension clamp works on the principle of clamping the wire through a wedge-shaped wire pressing plate in a through slot. When the wedge-shaped wire pressing plate is inserted into the through slot, it gradually approaches the central axis of the through slot under the action of the through slot hole wall. The arc groove on the side of the wedge-shaped wire pressing plate and the bottom surface of the through slot form a wire accommodating cavity. The side of the through hole central axis that the wedge-shaped wire pressing plate gradually approaches can be tightly pressed against the wire, which can prevent the wire from shifting between the wire pressing plates.

[0004] However, the use environment of tension clamps varies greatly. Some tension clamps that are exposed to wind and sun for a long time may fail to tighten the wires due to aging and deformation of the wedge-shaped wire pressing plate inside the clamp. When the wire is shaken by external force, the wedge-shaped wire pressing plate and the through groove may become loose, which may easily cause the wire to fall off the tension clamp, making it difficult to ensure the safety and stability of the wire.

[0005] The information disclosed in the background technology section of this application is only intended to deepen the understanding of the general background technology of this application, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Summary of the invention

[0006] Based on this, it is necessary to provide an anti-loosening type tension clamp to address the problems existing in the current tension clamps, so as to solve the problem that the existing wires and the tension clamps are easily separated.

[0007] In order to solve the above technical problems, a technical solution adopted by the present invention is:

[0008] Provided is an anti-loosening type tension clamp, comprising a positioning shell, a reinforcement body and a fastener, wherein a through slot is provided on the positioning shell; the reinforcement body comprises a first reinforcement block and a second reinforcement block slidably arranged in the through slot along a first sliding direction, the first reinforcement block and the second reinforcement block are used to clamp a wire, and mounting slots are provided on opposite side walls of the first reinforcement block and / or the second reinforcement block; the fastener comprises an anti-loosening ring, a rotating shaft and a limiting member, the anti-loosening ring is rotatably installed between the corresponding two side slot walls of the mounting slot through the rotating shaft, the wire passes through the anti-loosening ring, the anti-loosening ring clamps the wire when it rotates in the forward direction, and the limiting member always makes the anti-loosening ring rotate in the forward direction or has the tendency to rotate; wherein the anti-loosening ring rotates around the rotating shaft, and the first sliding direction is parallel to the length direction of the wire.

[0009] Furthermore, the first reinforcement block is provided with a slot, and the second reinforcement block is provided with a block adapted to the slot, and when the slot and the block are engaged, the relative sliding of the first reinforcement block and the second reinforcement block along the first sliding direction is restricted.

[0010] Furthermore, corresponding first sliding grooves are provided on the groove walls on opposite sides of the installation groove, and the two ends of the rotating shaft are respectively inserted into the two first sliding grooves, and the rotating shaft can slide along the length direction of the first sliding grooves;

[0011] The groove walls on both sides of the installation groove are provided with corresponding second sliding grooves, and the second sliding grooves are arranged parallel to the first sliding grooves;

[0012] The limiting member is arranged between the rotating shaft and the second sliding groove, and the limiting member can move synchronously with the movement of the rotating shaft.

[0013] Furthermore, the limiting member is a torsion spring, one end of which is fixedly connected to the rotating shaft, and the other end is inserted into the second slide groove and can slide along the length direction of the second slide groove. The elastic force of the torsion spring always causes the anti-loosening ring to rotate and press against the wire, or the elastic force of the torsion spring has a tendency to cause the anti-loosening ring to rotate.

[0014] Furthermore, the anti-loosening ring is a ring-shaped structural component.

[0015] Furthermore, a plurality of convex portions are provided on the surface of the anti-loosening ring.

[0016] Furthermore, anti-slip parts are provided on both side edges of the through slot.

[0017] Furthermore, a reinforcement strip is provided on the outer side wall of the positioning shell.

[0018] Furthermore, a mounting frame is provided on the positioning shell, and the mounting frame is connected to an external traction device via a reinforcement member.

[0019] Furthermore, one end of the positioning shell is provided with a matching connector that can be connected to an external fixing structure.

[0020] Different from the prior art, the beneficial effects of the present invention are:

[0021] In the anti-loosening type tension clamp provided by the present invention, the wire can be clamped by the first reinforcement block and the second reinforcement block, and can pass through the anti-loosening ring arranged in the installation groove. The anti-loosening ring can always rotate in the positive direction or have the tendency to rotate under the action of the limiter, so that the anti-loosening ring can always press against the wire, so that the wire can be in a relatively stable state with the first reinforcement block / the second reinforcement block, reducing the possibility of the wire detaching from the first reinforcement block / the second reinforcement block due to the shaking of the wire;

[0022] Compared with the existing tension-resistant wire clamps, the anti-loosening ring in the present invention can not only produce a certain pressure on the wire, but also can always be pressed against the wire under the action of the limit member, thereby increasing the friction between the wire and the anti-loosening ring, thereby increasing the external force required for the wire to detach from the first reinforcement block / the second reinforcement block, greatly reducing the possibility of the wire detaching from the anti-loosening type tension clamp due to loosening between the reinforcement body and the positioning shell or shaking of the wire.

[0040] The anti-loosening type tension clamp may include a positioning shell 100, a reinforcement body 200, and a fastener. It should be understood that the terms "include", "have", and any variations thereof used in the present invention are intended to cover non-exclusive inclusions.

[0041] The positioning shell 100 may be a structure of an indefinite shape. The positioning shell 100 may be a metal die-casting, or a structural member such as plastic or carbon fiber with high structural strength.

[0042] The positioning shell 100 is provided with a through slot 110 , and the through slot 110 can be opened on the positioning shell 100 by stamping, cutting, or the like.

[0043] Specifically, the cross-section of the through groove 110 can be an isosceles trapezoid, and the forward projections of the two side walls of the through groove 110 on its bottom surface correspond to the two waistlines of the isosceles trapezoid. Therefore, the two side walls of the through groove 110 are symmetrical with each other about the central axis of the through groove 110, and the two side walls of the through groove 110 gradually approach each other in the length direction along the central axis.

[0044] The reinforcement body 200 includes a first reinforcement block 210 and a second reinforcement block 220. The first reinforcement block 210 and the second reinforcement block 220 are both insulating members. The first reinforcement block 210 and the second reinforcement block 220 are used to clamp the wire and can be slidably arranged in the through slot 110 along a first sliding direction. The first sliding direction is the length direction of the wire, which is parallel to the length direction of the central axis of the through slot 110.

[0045] The two sides of the first reinforcing block 210 and the second reinforcing block 220 that are away from each other are parallel to the two side walls of the through slot 110. When the first reinforcing block 210 and the second reinforcing block 220 slide from the through slot 110, the two sides of the first reinforcing block 210 and the second reinforcing block 220 that are away from each other can contact and fit with the two side walls of the through slot 110 respectively.

[0046] In this embodiment, the end port of the through slot 110 with a smaller cross-sectional area can be defined as the top end of the through slot 110, and the end port with a larger cross-sectional area can be defined as the bottom end of the through slot 110. During the process of the first reinforcing block 210 and the second reinforcing block 220 sliding from the top end of the through slot 110 to the bottom end of the through slot 110, the distance between the two corresponding side surfaces of the first reinforcing block 210 and the second reinforcing block 220 will gradually decrease and gradually fit together.

[0047] Optionally, two opposite sides of the first reinforcement block 210 and the second reinforcement block 220 may be provided with wire grooves 2120, the wire grooves 2120 are parallel to the central axis of the through slot 110, and the wire grooves 2120 on the first reinforcement block 210 and the second reinforcement block 220 correspond to each other. The wires may be arranged between the wire grooves 2120 corresponding to each other in the first reinforcement block 210 and the second reinforcement block 220. In the process of the first reinforcement block 210 and the second reinforcement block 220 sliding from the top end of the through slot 110 to the bottom end of the through slot 110 in the through slot 110, the wire grooves 2120 on the first reinforcement block 210 and the second reinforcement block 220 can gradually clamp the wires, so that the first reinforcement block 210 and the second reinforcement block 220 can clamp the wires.

[0048] Specifically, the wire groove 2120 located on the first reinforcement block 210 has two ends that pass through the two ends of the first reinforcement block 210 respectively, and the wire groove 2120 located on the second reinforcement block 220 has two ends that pass through the two ends of the second reinforcement block 220 respectively. The groove wall of the wire groove 2120 can be an arc surface, a concave surface, or other surfaces that can guide or restrict the wire to a certain extent. A clamping line 2121 can be fixed on the groove surface of the wire groove 2120, and the clamping line 2121 can be a strip structure with a high friction coefficient such as a rubber strip. There can be multiple clamping lines 2121, and the multiple clamping lines 2121 are evenly distributed along the length direction of the wire groove 2120. The setting of the clamping line 2121 can make the first reinforcement block 210 and the second reinforcement block 220 clamp the wire more tightly.

[0049] The first reinforcing block 210 and / or the second reinforcing block 220 have mounting grooves 230 formed on their opposite sides. The mounting grooves 230 may be long strip-shaped grooves with their length direction parallel to the first sliding direction.

[0050] In this embodiment, mounting grooves 230 are provided on two opposite sides of the first reinforcement block 210 and the second reinforcement block 220, and the two mounting grooves 230 are correspondingly interconnected. Fasteners can be set in the two opposite mounting grooves 230. For convenience of description, the mounting groove 230 on the first reinforcement block 210 can be defined as a first mounting groove 231, and the mounting groove 230 on the second reinforcement block 220 can be defined as a second mounting groove 232.

[0051] The fastener includes an anti-loosening ring 310, a limiting member 320 and a rotating shaft 330. The anti-loosening ring 310 can be rotatably installed between the two opposite groove walls of the first installation groove 231 through the rotating shaft 330, and can extend into the second installation groove 232. The limiting member 320 can be arranged between the rotating shaft 330 and the side wall of the first installation groove 231, and the limiting member 320 always makes the anti-loosening ring 310 rotate in the positive direction or have the tendency to rotate.

[0052] Specifically, the axial direction of the rotating shaft 330 can be perpendicular to the first sliding direction and parallel to the bottom of the first mounting groove 231, and the two ends of the rotating shaft 330 can be respectively inserted into the two opposite side walls of the first mounting groove 231, and can be rotatably connected with the corresponding side walls of the first mounting groove 231. The anti-loosening ring 310 is installed on the rotating shaft 330 and can rotate around the rotating shaft 330. The limiting member 320 can be capable of applying a force to the rotating shaft 330 that allows the rotating shaft 330 to rotate in the positive direction or can make the rotating shaft 330 have a tendency to rotate in the positive direction, thereby enabling the anti-loosening ring 310 to rotate in the positive direction or have a tendency to rotate in the positive direction.

[0053] When the wire clamped between the first reinforcement block 210 and the second reinforcement block 220 passes through the anti-loosening ring 310, the anti-loosening ring 310 can always rotate in the positive direction or has a tendency to rotate in the positive direction under the action of the limiter 320 and the rotating shaft 330. The anti-loosening ring 310 rotating in the positive direction can press against the wire, thereby reinforcing the wire and reducing the possibility of the wire being separated from the first reinforcement block 210 and the second reinforcement block 220.

[0054] The implementation principle of this embodiment is as follows: the wire can be clamped in the through slot 110 by the first reinforcement block 210 and the second reinforcement block 220, and when the first reinforcement block 210 and the second reinforcement block 220 slide in the through slot 110, the closer to the bottom port of the through slot 110, the tighter the wire can be clamped. When the wire is clamped between the first reinforcement block 210 and the second reinforcement block 220, the wire can pass through the anti-loosening ring 310 set in the installation slot 230, and the anti-loosening ring 310 always has a tendency to rotate in the forward direction under the action of the limiter 320 and the rotating shaft 330, and this tendency can make the anti-loosening ring 310 press against the wire to achieve reinforcement of the wire.

[0055] When the present invention is applied in an environment such as strong winds that can cause the present invention to shake, looseness may occur between the positioning shell 100 and the first reinforcement block 210 and the second reinforcement block 220. At this time, the wire clamped between the first reinforcement block 210 and the second reinforcement block 220 may obtain a pulling force to separate from the first reinforcement block 210 and the second reinforcement block 220. This pulling force may push the wire to move from the bottom of the through slot 110 toward the top of the through slot 110, and may also push the wire to move from the top of the through slot 110 toward the bottom of the through slot 110.

[0056] When the wire moves from the bottom of the through groove 110 toward the top of the through groove 110, the wire can be pressed by the anti-loosening ring 310, thereby increasing the friction between the wire and the anti-loosening ring 310, making it difficult for the wire to move relative to the anti-loosening ring 310, thereby reducing the possibility of the wire detaching from the first reinforcement block 210, thereby ensuring the safety and stability of the wire in the present invention.

[0057] When the wire moves from the top of the through groove 110 to the direction close to the bottom of the through groove 110, the wire is not only subjected to the pressure of the anti-loosening ring 310, but also exerts a pulling force on the anti-loosening ring 310 in the same direction as the moving direction of the wire due to the friction force. The force exerted by the wire on the anti-loosening ring 310 can make the anti-loosening ring 310 have a tendency to deflect in a direction parallel to the central axis of the through groove 110. At this time, the anti-loosening ring 310 will exert a greater pressure on the wire, and the anti-loosening ring 310 may be self-locking on the wire, making it more difficult to separate from the wire.

[0058] It should be noted that, without human intervention, the application environment of the present invention may cause the first reinforcement block 210, the second reinforcement block 220 and the positioning shell 100 to loosen, but the extent of the loosening will be small, and the force on the wire will also be small.

[0059] In some embodiments, the first reinforcing block 210 may be provided with a card slot 211, and the second reinforcing block 220 may be provided with a card block 221 adapted to the card slot 211. When the first reinforcing block 210 and the second reinforcing block 220 slide along the side walls of their respective through slots 110, and simultaneously slide from the top end of the through slot 110 to the bottom end of the through slot 110, the card block 221 on the second reinforcing block 220 can be inserted into the card slot 211 corresponding to the first reinforcing block 210 to achieve card connection, thereby enabling the first reinforcing block 210 and the second reinforcing block 220 to slide synchronously in the through slot 110.

[0060] Specifically, the two corresponding sides of the first reinforcing block 210 and the second reinforcing block 220 can be respectively defined as a first side 2101 and a second side 2201. The card slot 211 can be provided on the first side 2101, and the side thereof facing the bottom surface of the through slot 110 penetrates the first reinforcing block 210. The card block 221 can be provided on the second side 2201, and corresponds to the card slot 211.

[0061] In this embodiment, the clamping block 221 arranged on the second reinforcement block 220 can be inserted into the corresponding clamping slot 211 on the first reinforcement block 210 during the process of clamping the wire. If the first reinforcement block 210 slides with the positioning shell 100, the second reinforcement block 220 will slide accordingly, so that the wire can always be located between the first reinforcement block 210 and the second reinforcement block 220, and can move synchronously with the first reinforcement block 210 and the second reinforcement block 220, ensuring that the contact and connection position of the wire remains unchanged, thereby ensuring the safety and stability of the wire.

[0062] Of course, the first reinforcement block 210 and the second reinforcement block 220 can also be snap-connected outside the through groove 110. At this time, the first reinforcement block 210 and the second reinforcement block 220 after snap-connection can slide into the through groove 110 simultaneously along the first sliding direction. Before the first reinforcement block 210 and the second reinforcement block 220 are fitted with the side walls corresponding to the through groove 110, the wire is inserted between the first reinforcement block 210 and the second reinforcement block 220 and passed through the anti-loosening ring 310, which can also achieve clamping of the wire.

[0063] In some embodiments, the limiting member 320 may be a structural member having torsional elastic force, such as a coil spring (not shown in the figure).

[0064] In this embodiment, a coil spring is used as an example, and two coil springs can be provided, and both coil springs are sleeved on the rotating shaft 330 and are respectively close to the two ends of the rotating shaft 330. Among them, one end of the coil spring is fixedly connected to the rotating shaft 330, and the other end of the coil spring is fixedly connected to the groove wall of the first installation groove 231 adjacent to it.

[0065] In this embodiment, under the action of the torsion force of the coil spring, the anti-loosening ring 310 rotatably mounted in the first mounting groove 231 via the rotating shaft 330 can obtain a positive rotation trend. At this time, if the wire passes through the anti-loosening ring 310, the anti-loosening ring 310 will press against the wire, which can reinforce the wire and reduce the possibility of separation between the wire and the first reinforcement block 210 and the second reinforcement block 220.

[0066] In other embodiments, first slide grooves 2311 corresponding to each other are provided on the groove walls on opposite sides of the first installation groove 231. The length direction of the first slide groove 2311 can be perpendicular to the central axis of the through groove 110, and its two ends are respectively close to the groove bottom and the groove opening of the first installation groove 231. In this embodiment, the two ends of the rotating shaft 330 can be respectively inserted into the two first slide grooves 2311 corresponding to each other in the first installation groove 231, and can slide along the length direction of the first slide groove 2311.

[0067] Meanwhile, second slide grooves 2312 corresponding to each other are also provided on the two opposite groove walls of the first installation groove 231 , and the second slide grooves 2312 are arranged parallel to the first slide grooves. The first slide grooves 2311 and the second slide grooves 2312 can be distributed in sequence along the length direction of the first installation groove 231 .

[0068] In this embodiment, the stopper 320 can be a structural member with torsion elastic force such as a torsion spring 321 or a coil spring. Taking the torsion spring 321 as an example, two torsion springs 321 can be provided on the rotating shaft 330, and the two torsion springs 321 are both sleeved on the rotating shaft 330 and are respectively close to the two ends of the rotating shaft 330. Among them, one end of the torsion spring 321 is fixedly connected to the rotating shaft 330, and the other end of the torsion spring 321 can be inserted into the second slide groove 2312 close to it, and can slide along the length direction of the second slide groove 2312.

[0069] When the wire passes through the anti-loosening ring 310 and is subjected to the pulling force of the external environment, the anti-loosening ring 310 may deflect due to the friction between it and the wire. When the anti-loosening ring 310 deflects, it will drive the rotating shaft 330 to slide in the first slide groove 2311. The sliding of the rotating shaft 330 will drive the torsion spring 321 to slide in the second slide groove 2312, so that the torsion spring 321 can continue to apply pressure to the anti-loosening ring 310 to press against the wire. At the same time, the synchronous sliding of the rotating shaft 330 and the torsion spring 321 can also make the direction of the friction between the anti-loosening ring 310 and the wire as parallel to the length direction of the wire as possible, making it more difficult for the wire to escape from the anti-loosening ring 310.

[0070] In some embodiments, fixing blocks 2301 with high structural strength are arranged on the groove walls on both sides of the first installation groove 231. The fixing blocks 2301 may be metal blocks. The fixing blocks 2301 are fixed to the groove walls corresponding to the first installation groove 231. The specific fixing method may be embedding, nailing, etc. The first slide groove 2311 and the second slide groove 2312 in the above embodiments are both provided on the corresponding fixing blocks 2301.

[0071] The fixed block 2301 can strengthen the structural strength of the first slide groove 2311 and the second slide groove 2312, so that when the rotating shaft 330 and the limit member 320 move along their respective corresponding slide grooves, the corresponding slide groove structure will not be damaged due to excessive elastic force of the limit member 320 or excessive deflection of the anti-loosening ring 310 under the action of the wire.

[0072] In some embodiments, the anti-loosening ring 310 can be a workpiece with strong structural strength such as a metal part or a plastic part produced by die casting, cutting, etc. The anti-loosening ring 310 can be a ring-shaped structural part, specifically a circular ring-shaped, elliptical ring-shaped, square ring-shaped, etc. ring-shaped structural part.

[0073] In this embodiment, the anti-loosening ring 310 may be in the shape of an elliptical ring, and the rotating shaft 330 is fixed to one end of the long axis of the anti-loosening ring 310 , and the rotating shaft 330 is arranged at an angle to the long axis of the anti-loosening ring 310 .

[0074] The surface of the anti-loosening ring 310 may be provided with a plurality of convex portions 311, and the plurality of convex portions 311 may be evenly distributed on the surface of the anti-loosening ring 310. The arrangement of the convex portions 311 increases the surface roughness of the anti-loosening ring 310. When the wire passes through the anti-loosening ring 310, the friction between the wire and the anti-loosening ring 310 will be greater, and it will be more difficult for the wire to脱离 the anti-loosening ring 310.

[0075] In some embodiments, anti-disengagement members 111 may be provided at the notch and the corresponding two side edges of the through groove 110. The anti-disengagement members 111 may be configured as sheet-like, block-like or strip-like structural members, and their main function is to prevent the object slidably disposed in the through groove 110 from disengaging from the notch of the through groove 110.

[0076] In some embodiments, a reinforcing strip 120 is provided on the outer side wall of the positioning shell 100. The reinforcing strip 120 may be a metal strip, which can enhance the structural strength of the positioning shell 100. The reinforcing strip 120 may be a "U"-shaped strip. The two side strips of the reinforcing strip 120 may be respectively fixedly connected to the two side walls of the positioning shell 100, and the middle strip of the reinforcing strip 120 may be fixedly connected to the side surface of the positioning shell 100 facing away from the through groove 110.

[0077] A plurality of reinforcing strips 120 may be provided, and the plurality of reinforcing strips 120 are evenly distributed on the surface of the positioning shell 100 along the length direction of the central axis of the through groove 110.

[0078] In some other embodiments, a mounting bracket 130 may be provided on the positioning shell 100. The mounting bracket 130 may include two connecting pieces 131. The two connecting pieces 131 are respectively disposed on both sides of the positioning shell 100 and are respectively rotatably connected to the two side surfaces of the positioning shell 100.

[0079] The connecting piece 131 may be a sheet-like structural member with a zigzag shape, and the two connecting pieces 131 may be connected by a reinforcing member 132. The reinforcing member 132 may be selected as a bolt, a rivet or other structural members that can fix the two connecting pieces 131 together.

[0080] When the present invention is actually applied, the external traction device can lift the mounting bracket 130, and the mounting bracket 130 can drive the present strain clamp to its installation position, which is more convenient for the actual installation of the present invention.

[0081] In addition, a mating connecting member 140 capable of connecting with an external fixed structure may be provided at the bottom end of the positioning shell 100. The mating connecting member 140 may be configured as a metal ring, a metal loop or other structural members with a certain structural strength.

[0082] When the present invention is hoisted to its installation position, the matching connector 140 can be fixed to the external fixed structure by bolts, pins and other connecting structural members to reduce the possibility of shaking of the present invention. The external fixed structure can be a fixed structure such as a telephone pole, a mast, an insulator, etc.

[0083] It should be clear that in the above-mentioned embodiments, when a wire is arranged between the first reinforcement block 210 and the second reinforcement block 220, the wire passes through the anti-loosening ring 310, and under the action of the limiting member 320, the anti-loosening ring 310 can be pressed against the wire. Since the anti-loosening ring 310 is affected by the elastic force of the limiting member 320 and the wire, the anti-loosening ring 310 is inclined in the corresponding installation groove 230. Therefore, in the traveling direction of the wire, there are one or two contact points between the anti-loosening ring 310 and the wire.

[0084] When there is only one contact point between the anti-loosening ring 310 and the wire, in the length direction of the wire, the contact point is on the anti-loosening ring 310 away from the rotating shaft 330. At this time, the anti-loosening ring 310 is pressed against the wire under the action of the stopper 320, which can reduce the possibility of the wire escaping from the anti-loosening ring 310.

[0085] When there are two contact points between the anti-loosening ring 310 and the wire, the two contact points are respectively close to and far away from the rotating shaft 330 in the traveling direction of the wire. Under the action of the limiter 320, the contact point of the anti-loosening ring 310 close to the rotating shaft 330 can press against the wire, and the contact point of the anti-loosening ring 310 far away from the rotating shaft 330 can also press against the wire. At this time, the wire is subjected to the force applied by the anti-loosening ring 310 in two directions, and the two directions are opposite. The opposite forces applied to the wire can only make the wire and the anti-loosening ring 310 closer, so that the friction force to be overcome when the wire is separated from the anti-loosening ring 310 will be greater, and it will be more difficult to separate from the anti-loosening ring 310, so that the synchronous movement of the wire and the first reinforcement block 210 and the second reinforcement block 220 can be achieved, which greatly reduces the possibility of the wire separating from the first reinforcement block 210 and the second reinforcement block 220.

[0086] See also Fig.11 , Fig.11 It is a schematic diagram for reference of the forces between the wire and the anti-loosening ring 310 when the wire moves from the bottom end of the through slot toward the top end of the through slot in some embodiments of the present invention.

[0087] When there are two contact points between the anti-loosening ring 310 and the wire, and the anti-loosening ring 310 is in the shape of a ring, the point a close to the rotating shaft 330 and the point b far from the rotating shaft 330 on the anti-loosening ring 310 can both apply pressure to the wire. The pressure applied by the point a of the anti-loosening ring 310 on the wire is F1, and the pressure applied by the point b of the anti-loosening ring 310 on the wire is F2. The directions of F1 and F2 are opposite. At this time, whether the wire moves upward or downward under the influence of external force, it is necessary to overcome the friction force applied by the anti-loosening ring 310 at points a and b, i.e., f1 and f2. The friction force applied by the anti-loosening ring 310 on the wire greatly limits the movement of the wire and reduces the possibility of the wire detaching from between the first reinforcement block 210 and the second reinforcement block 220.

[0088] Of course, if the wire is thicker or the anti-loosening ring 310 is an irregular ring shape, when the wire passes through the anti-loosening ring 310, there may be more than two contact points between the wire and the anti-loosening ring 310. However, the pressure applied by the anti-loosening ring 310 to the wire at each contact point is perpendicular to the length direction of the wire. If the wire is to move, the friction force applied to the wire at each contact point must be overcome. Therefore, it is difficult for the wire to move in the anti-loosening ring 310, which can greatly reduce the possibility of the wire escaping from the present invention.

[0089] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0090] The above-described embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
