[0028] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0029] See also Figure 1-8An embodiment of the present invention provides a wire clamping and fixing mechanism for power equipment, comprising a fixed base 1, a movable base 2, a first semi-circular disk 3, a second semi-circular disk 4 and a locking assembly. Among them, a plurality of first clamping members are rotatably connected to the fixed base 1, and a plurality of mounting holes 34 for facilitating the installation of the fixed base 1 are provided on one side of the fixed base 1. The first semi-circular disk 3 is coaxially rotatably connected to the fixed base 1, and each first clamping member is slidably and rotatably connected to the first semi-circular disk 3 through a first sliding sleeve 32. The movable base 2 is coaxially rotatably connected to the second semi-circular disk 4, and a plurality of second clamping members are rotatably connected to the movable base 2, and each second clamping member is slidably and rotatably connected to the second semi-circular disk 4 through a second sliding sleeve 33. Please refer to Figure 7 and Figure 8 One arcuate end of the second semi-disc 4 is hinged to one arcuate end of the first semi-disc 3, one arcuate end of the first semi-disc 3 is provided with a third rotating shaft 26, one arcuate end of the second semi-disc 4 is rotatably connected to the third rotating shaft 26, so that the second semi-disc 4 can rotate relative to the first semi-disc 3, and the second semi-disc 4 can rotate relative to the first semi-disc 3 until it embraces the first semi-disc 3 to form a circular structure.

[0030] See also Figure 3 and Figure 6 The locking assembly is assembled so that when the second semi-circular disk 4 and the first semi-circular disk 3 form a circular structure, the circular structure can be driven to rotate so that the movable base 2 is locked to the fixed base 1, and each first clamping member and the second clamping member are synchronously closed centripetally to clamp the fixed wire. The locking assembly includes a locking unit and a driving unit. The locking unit includes a first connecting rod 5, a second connecting rod 6 and a sliding column 7. One end of the first connecting rod 5 is fixedly connected to the arc end of the first semi-circular disk 3 away from the third rotating shaft 26. One end of the first connecting rod 5 away from the first semi-circular disk 3 is rotatably connected to one end of the second connecting rod 6 through the fourth rotating shaft 27. One end of the second connecting rod 6 away from the first connecting rod 5 is fixedly connected to the sliding column 7. A first sliding groove 8 is provided on the fixed base 1, and the sliding column 7 slides along the first sliding groove 8. A second sliding groove 9 with a notch at one end is provided on the movable base 2. The first slide groove 8 and the second slide groove 9 are both arc-shaped. When the movable base 2 is aligned with the fixed base 1, the first slide groove 8 and the second slide groove 9 completely overlap. The slide column 7 is located at the notch of the second slide groove 9 and can slide with the second slide groove 9. The driving unit is used to drive the circular structure to rotate.

[0031] See also Figure 1 and Figure 4 In an example provided by the present invention, the driving unit includes a screw rod 10, a connecting block 11 and a threaded sleeve 12. The connecting block 11 is rotatably connected to the fixed base 1, the threaded sleeve 12 is rotatably connected to the protrusion of the first semi-circular disk 3, the screw rod 10 is rotatably connected to the connecting block 11, the screw rod 10 is threadedly connected to the threaded sleeve 12, and one end of the screw rod 10 is fixedly connected to a knob 13.

[0032] When the first semi-circular disk 3 and the second semi-circular disk 4 are aligned to form a circular structure, the knob 13 is turned to move the threaded sleeve 12 relative to the connecting block 11. In the process of the threaded sleeve 12 moving away from the connecting block 11, the circular structure rotates, and the rotating circular structure will produce two effects at the same time. One is to make the first clamping members and the second clamping members synchronously close together, which can adapt to wires of different diameters and fix the wires. The other is that the rotation of the circular structure also makes the sliding post 7 at the notch of the second slide groove 9 slide toward the end of the second slide groove 9. The sliding post 7 locks the movable base 2 aligned with the fixed base 1 to the fixed base 1 during the sliding stroke. In the process of the threaded sleeve 12 moving toward the connecting block 11, the circular structure rotates in the opposite direction. The reverse rotating circular structure will also produce two effects. One is to drive the first clamping members and the second clamping members to synchronously centrifugally disperse to release the clamped and fixed wires. In this state, if you want to clamp the wire, you can let the end of the wire pass between each first clamping member and each second clamping member to clamp the wire; second, the circular structure rotates in the opposite direction to make the slide post 7 near the end of the second slide groove 9 slide toward the notch of the second slide groove 9. When the threaded sleeve 12 abuts against the connecting block 11, the slide post 7 slides to the notch of the second slide groove 9, the movable base 2 is unlocked from the fixed base 1, and the second semi-circular disk 4 can be rotated through the third rotating shaft 26 to completely separate the movable base 2 from the fixed base 1. In this state, if you want to clamp the wire, you can insert it from the middle of the wire to clamp the wire.

[0033] In another example provided by the present invention, the driving unit includes an electric cylinder, wherein the motor on the electric cylinder is rotatably connected to the fixed base 1, and the slider on the electric cylinder is rotatably connected to the first semi-circular disk 3. When the first semi-circular disk 3 and the second semi-circular disk 4 are aligned to form a circular structure, the motor can drive the slider to slide, so that the circular structure rotates.

[0034] In another example provided by the present invention, the driving unit includes a hydraulic cylinder, wherein the cylinder body on the hydraulic cylinder is rotatably connected to the fixed base 1, and the piston rod on the hydraulic cylinder is rotatably connected to the first semi-circular disk 3. When the first semi-circular disk 3 and the second semi-circular disk 4 are aligned to form a circular structure, the piston rod moves relative to the cylinder body to rotate the circular structure.

[0035] See also Figure 1 and Figure 4, wherein the first clamping member includes a first elastic member and a first rod body 15 and a second rod body 16 that are slidably connected along the axial direction of the circular structure. The side of the second rod body 16 that contacts the wire is an arc-shaped end face. When the wire is to be fixed, the arc-shaped end face can cover the wire as much as possible to prevent the wire from slipping after being fixed. The end of the first rod body 15 away from the second rod body 16 is fixedly connected to the first rotating shaft 24, and the end of the first rotating shaft 24 away from the first rod body 15 is rotatably connected to the fixed base 1. The first rod body 15 is slidably connected to the corresponding first sliding sleeve 32, and each first sliding sleeve 32 is rotatably connected to the first semi-circular disk 3. The process of restoring the deformation of the first elastic member drives the second rod body 16 to be in the middle of the sliding stroke relative to the first rod body 15. The end of the first rod body 15 close to the second rod body 16 is fixedly connected to the first limit frame 17, and the first limit frame 17 is fixedly connected to the first slide bar 18, and the second rod body 16 is slidably arranged on the first slide bar 18. When the second rod 16 slides relative to the first rod 15 , the first limiting frame 17 can prevent the second rod 16 from falling off the first sliding rod 18 .

[0036] The first elastic member includes a first tension spring 14 , one end of which is hooked on the first rod body 15 through a first hanging rod 28 , and the other end of which is hooked on the second rod body 16 through a second hanging rod 29 . When the clamped and fixed wire is not pulled by external force, the wire is in a relaxed state, and the second rod 16 is in the middle position of the sliding stroke relative to the first rod 15. At this time, the first tension spring 14 has been stretched to produce elastic deformation; when the clamped and fixed wire is pulled by external force, the wire is in a taut state, and the second rod 16 also slides relative to the first rod 15, the first tension spring 14 is further stretched, and the tension generated by the elastic deformation of the first tension spring 14 is further increased. The trend that the tension drives the second rod 16 to be in the middle of the sliding stroke relative to the first rod 15 becomes more and more obvious, and the tension can also relieve the taut state of the wire to a certain extent, and prevent the wire from being broken due to rigid pulling; when the external force gradually decreases or disappears, the first tension spring 14 gradually recovers its deformation, the tension gradually decreases and drives the second rod 16 to be in the middle of the sliding stroke relative to the first rod 15, and the wire also recovers from the taut state to the relaxed state.

[0037] See also Figure 2 and Figure 5, wherein the second clamping member includes a second elastic member and a third rod body 20 and a fourth rod body 21 that are slidably connected along the axial direction of the circular structure. The side of the fourth rod body 21 that contacts the wire is an arc-shaped end face. When the wire is to be fixed, the arc-shaped end face can cover the wire as much as possible to prevent the fixed wire from slipping. The end of the third rod body 20 away from the fourth rod body 21 is fixedly connected to the second shaft 25, and the end of the second shaft 25 away from the third rod body 20 is rotatably connected to the movable base 2. The third rod body 20 is slidably connected to the corresponding second sliding sleeve 33, and each second sliding sleeve 33 is rotatably connected to the second semi-circular disk 4. The process of the second elastic member restoring the deformation drives the fourth rod body 21 to be in the middle of the sliding stroke relative to the third rod body 20. The end of the third rod body 20 close to the fourth rod body 21 is fixedly connected to the second limit frame 22, and the second limit frame 22 is fixedly connected to the second slide bar 23. The fourth rod body 21 is slidably arranged on the second slide bar 23. When the fourth rod 21 slides relative to the third rod 20 , the second limiting frame 22 can prevent the fourth rod 21 from falling off the second sliding rod 23 .

[0038] The second elastic member includes a second tension spring 19 , one end of the second tension spring 19 is hooked on the third rod body 20 through a third hanging rod 30 , and the other end of the second tension spring 19 is hooked on the fourth rod body 21 through a fourth hanging rod 31 . When the clamped and fixed wire is not pulled by external force, the wire is in a relaxed state, and the fourth rod 21 is in the middle position of the sliding stroke relative to the third rod 20. At this time, the second tension spring 19 has been stretched to produce elastic deformation; when the clamped and fixed wire is pulled by external force, the wire is in a taut state, which also causes the fourth rod 21 to slide relative to the third rod 20, and the second tension spring 19 is further stretched. The tension generated by the elastic deformation of the second tension spring 19 is further increased, and the trend of the tension driving the fourth rod 21 to be in the middle of the sliding stroke relative to the third rod 20 becomes more and more obvious. The tension can also relieve the taut state of the wire to a certain extent, and prevent the wire from being broken due to rigid pulling; when the external force gradually decreases or disappears, the second tension spring 19 gradually recovers its deformation, the tension gradually decreases and drives the fourth rod 21 to be in the middle of the sliding stroke relative to the third rod 20, and the wire also recovers from the taut state to the relaxed state.

[0039] Working principle: When the first semi-circular disk 3 and the second semi-circular disk 4 are combined to form a circular structure, and the movable base 2 and the fixed base 1 are matched, the first slide groove 8 and the second slide groove 9 are completely overlapped, and the slide post 7 is located at the gap of the second slide groove 9. When the knob 13 on the screw rod 10 is turned to make the threaded sleeve 12 move away from the connecting block 11, the circular structure rotates, so that each first sliding sleeve 32 rotatably connected to the first semi-circular disk 3 and each second sliding sleeve 33 rotatably connected to the second semi-circular disk 4 move with the rotation of the circular structure, and the corresponding first clamping member slidably connected in the first sliding sleeve 32 and the corresponding second clamping member slidably connected in the second sliding sleeve 33 both move centripetally, and finally each first clamping member and each second clamping member are synchronously closed centripetally to clamp the wire; at the same time, the rotation of the circular structure also causes the slide post 7 to slide from the gap of the second slide groove 9 to the end of the second slide groove 9, locking the movable base 2 and the fixed base 1.

[0040] On the contrary, when the knob 13 on the screw 10 is turned to make the threaded sleeve 12 approach the connecting block 11, the circular structure rotates in the opposite direction, and finally the first clamping members and the second clamping members are synchronously centrifugally expanded to loosen the wire, and at the same time, the slide post 7 slides from the end of the second slide groove 9 to the notch. When the threaded sleeve 12 abuts against the connecting block 11, the slide post 7 is located at the notch of the second slide groove 9, and the movable base 2 is unlocked from the fixed base 1.

[0041] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
