[0013] Beneficial Effects

[0014] 1. In the present invention, the movable hook rod is vertically slidably installed in the hook-pull stroke hole, and the guide seat is vertically fixedly installed at the hole edge at the lower end of the hook-pull stroke hole. The movable hook rod can slide vertically in the hook-pull stroke hole, so that the cable can be hooked and fixed in cooperation with the fixed barb, which is convenient for cable arrangement.

[0015] 2. In the present invention, when the wire drawing frame moves to the outermost position of the wire drawing stroke hole, it is in a state to be clamped and drawn. At this time, the movable wire drawing seat is at the sunken bend of the upper wire drawing stroke hole, and the fixed wire drawing seat and the movable wire drawing seat are in a separated state, which can facilitate the insertion of the cable. When the cable is placed between the upper and lower groups of "8"-shaped wire wheels, the movable wire drawing seat is pulled up, so that the movable wire drawing seat and the fixed wire drawing seat move inward under the action of the tension spring, so that the cable can be straightened, which is convenient for wiring and avoids the cable protruding during the wiring process.

[0016] 3. In the present invention, a spring C is mounted on the guide rod below the front pull block. When in use, the movable hook rod can be pressed down so that the cable is hung on the movable hook rod. The movable hook rod can automatically reset upward under the action of the spring C and cooperate with the fixed hook to hook and fix the cable, thereby preventing the cable from falling out and effectively arranging the cables.

[0017] 4. When the cable needs to be inserted into the wire clamping sleeve of the present invention, the cable can be inserted by directly pressing it internally. During the process of internal pressure of the cable, the cable squeezes the inclined surface of the lower end of the stop rod, so that the stop rod moves upward. After the cable is inserted, the stop rod moves back to its original position under the action of the opposite polarity attraction between the magnetic suction ring and the magnetic suction cup. At this time, the cable can be prevented from escaping from the wire clamping sleeve, and the cable is limited and fixed. When the cable needs to be taken out, it is only necessary to pull the stop rod upward. When the anti-rotation wing escapes from the socket, the stop rod is rotated 180 degrees to loosen the stop rod. The stop rod returns to its original position under the action of the opposite polarity attraction between the magnetic suction ring and the magnetic suction cup. At this time, the cable can be directly pulled out when needed, which is convenient for the cable to be transferred to another position for adaptation and connection.

[0018] 5. When the cable needs to be arranged and turned, the pull ring can be pulled to move the locking positioning rod outward and out of the angle locking groove. At this time, the angle adjustment seat can be rotated, and the locking positioning rod can be released and positioned and fixed again under the action of spring B, so that the cable can be bent and arranged, making the cable arrangement more diverse and adaptable.

A tension spring 405 is mounted on the guide rod 404 between the rear ends of the shaft rods of the fixed wire drawing seat 401 and the rear ends of the shaft rods of the movable wire drawing seat 402. The fixed wire drawing seat 401 and the movable wire drawing seat 402 are both longitudinally rotatably mounted with two "8"-shaped wire wheels parallel to each other. When the wire drawing frame 4 moves to the outermost position of the wire drawing stroke hole 101, it is in a state of waiting to clamp and draw the wire. At this time, the movable wire drawing seat 402 is in the upper drawing position. The cable travel hole 101 is at a sunken bend, and the fixed wire-winding seat 401 and the movable wire-winding seat 402 are in a separated state, which can facilitate the insertion of the cable. When the cable is inserted between the upper and lower groups of "8"-shaped wire wheels, the movable wire-winding seat 402 is pulled, so that the movable wire-winding seat 402 and the fixed wire-winding seat 401 move inward under the action of the tension spring 405, so that the cable can be straightened, which is convenient for wiring and avoids the cable from protruding during the wiring process.

[0038] like Figure 1 and Fig. 9 As shown, the front end of the movable hook rod 3 is a hook-shaped structure corresponding to the fixed hook 2; a correction rod 301 is fixedly installed vertically backward at the middle position of the rod body of the movable hook rod 3, and the rod bodies of the correction rod 301 and the movable hook rod 3 both pass backward from the hook-pull stroke hole 103, and a front pull block 303 and a rear pull block 302 are fixedly installed on the correction rod 301 at the positions on the front and rear sides of the hook-pull stroke hole 103, respectively; a guide rod 801 is fixedly installed vertically upward on the top plane of the guide seat 8, and the inner side of the corresponding front pull block 303 is vertically slidably sleeved on the guide rod 801; a spring C802 is sleeved on the guide rod 801 below the front pull block 303, and when in use, the movable hook rod 3 can be pressed down so that the cable is hung on the movable hook rod 3, and the movable hook rod 3 can automatically reset upward under the action of the spring C802 and cooperate with the fixed hook 2 to loop and hook the cable to fix it, thereby preventing the cable from falling out and effectively arranging the cables.

[0039] like Figure 1 , Figure 7 and Figure 8 As shown, a semi-cylindrical wire-clamping sleeve 501 is fixedly installed at the front end of the angle adjustment seat 5, and the wire-clamping sleeve 501 is made of insulating rubber material. A stop rod 701 is symmetrically installed vertically and slidably in the side clamping block 7, and the lower end of the stop rod 701 is a structure beveled backward and downward, and a magnetic suction cup 702 is fixedly installed on the upper end of the side clamping block 7, and a pull rod is vertically fixedly installed on the upper end of the magnetic suction cup 702. A magnetic suction ring 703 is embedded and fixedly installed at the periphery of the jack at the position of the stop rod 701 on the side clamping block 7, and the polarity of the magnetic suction ring 703 is different from that of the magnetic suction cup 702; vertical anti-rotation wings 704 are symmetrically fixedly installed on the stop rod 701 below the magnetic suction cup 702, and the length of the anti-rotation wings 704 is exactly the distance between the top surface of the magnetic suction ring 703 and the upper surface of the inner cavity of the wire-clamping sleeve 501. The cable is inserted into the wire sleeve 501 and the cable can be inserted by directly pressing it internally. During the cable internal pressure process, the cable squeezes the inclined surface of the lower end of the stop rod 701, causing the stop rod 701 to move upward. After the cable is inserted, the stop rod 701 moves back to its original position under the action of the opposite polarity attraction between the magnetic ring 703 and the magnetic suction cup 702. At this time, the cable can be prevented from escaping from the wire sleeve 501, thereby completing the cable limit fixation. When the cable needs to be taken out, it is only necessary to pull up the stop rod 701. When the anti-rotation wing 704 is escaping from the socket, the stop rod 701 is rotated 180 degrees to loosen the stop rod 701. The stop rod 701 returns to its original position under the action of the opposite polarity attraction between the magnetic ring 703 and the magnetic suction cup 702. At this time, the cable can be directly pulled out when needed, which is convenient for the cable to be transferred to another position for adaptation and connection.

[0040] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the wiring board 1 at the position of the angle adjustment seat 5 is annularly distributed with angle locking grooves 102, and a locking positioning rod 601 is vertically and longitudinally slidably installed on the locking positioning frame 6, a baffle 602 is fixedly installed on the locking positioning rod 601 near the rear end, and a pull ring 604 is fixedly installed at the front end of the locking positioning rod 601; a spring B603 is sleeved on the locking positioning rod 601 between the baffle 602 and the locking positioning frame 6, and the rear end part of the locking positioning rod 601 is slidably inserted in the angle locking groove 102. When it is necessary to make a turn in the cable arrangement, the pull ring 604 can be pulled to make the locking positioning rod 601 move outward and escape from the angle locking groove 102. At this time, the angle adjustment seat 5 can be rotated, and the locking positioning rod 601 can be released and positioned and fixed again under the action of the spring B603, so that the cables can be bent and arranged, making the cable arrangement more diverse and adaptable.

[0041] Specific usage and function of this embodiment: During use of the present invention, the wiring board 1 is first installed in the distribution box. Two vertical hook-pull travel holes 103 that penetrate front and back are symmetrically opened in the middle of the wiring board 1. The movable hook rod 3 is vertically slidably installed in the hook-pull travel hole 103, and the guide seat 8 is vertically fixedly installed at the hole edge of the lower end of the hook-pull travel hole 103. The movable hook rod 3 can slide vertically in the hook-pull travel hole 103, and the lower end of the wire drawing frame 4 is vertically fixedly installed with a fixed wire drawing seat 401 through a shaft rod. The lower end of the wire drawing frame 4 slides vertically backward through the shaft rod and is placed in the wire drawing travel hole 101 below. The upper end of the wire drawing frame 4 is vertically fixedly installed with a The movable wire drawing seat 402, the upper end of the wire drawing frame 4 passes vertically backward through the upper wire drawing stroke hole 101 through the shaft rod, the rear end of the shaft rod of the fixed wire drawing seat 401 is vertically fixedly installed with a guide rod 404, the upper end of the guide rod 404 slides vertically through the rear end of the shaft rod of the movable wire drawing seat 402, and the guide rod 404 between the rear end of the shaft rod of the fixed wire drawing seat 401 and the rear end of the shaft rod of the movable wire drawing seat 402 is sleeved with a tension spring 405, and the fixed wire drawing seat 401 and the movable wire drawing seat 402 are both longitudinally rotatably installed with two "8"-shaped wire wheels parallel to each other. When the wire drawing frame 4 moves to the outermost end position of the wire drawing stroke hole 101, it is in a state to be clamped and wired. At this time The movable wire-winding seat 402 is located at the sunken bending part of the upper wire-winding stroke hole 101, while the fixed wire-winding seat 401 and the movable wire-winding seat 402 are in a phase-separated state, which can facilitate the insertion of the cable. When the cable is inserted between the upper and lower sets of "8"-shaped wire wheels, the movable wire-winding seat 402 is pulled up, so that the movable wire-winding seat 402 and the fixed wire-winding seat 401 move inwardly under the action of the tension spring 405. When the cable needs to be inserted into the wire clamping sleeve 501, the cable can be inserted by directly pressing it internally. During the process of internal pressure of the cable, the cable squeezes the inclined surface of the lower end of the stop rod 701, so that the stop rod 701 moves upward. After the cable is inserted, the magnetic ring 703 and the magnetic suction cup 702 have opposite polarities and attract each other. When the cable is to be taken out, the stop rod 701 only needs to be pulled upwards. When the anti-rotation wing 704 is to be disengaged from the jack, the stop rod 701 is rotated 180 degrees to release the stop rod 701. The stop rod 701 returns to its original position under the action of the opposite polarities of the magnetic ring 703 and the magnetic suction cup 702. When the cable needs to be turned, the pull ring 604 can be pulled to make the locking positioning rod 601 move outwards and disengage from the angle locking groove 102. At this time, the angle adjustment seat 5 can be rotated. The locking positioning rod 601 is released and can be positioned and fixed again under the action of the spring B603.

[0042] Finally, it should be noted that when describing the position of each component and the matching relationship between them, the present invention usually takes one / a pair of components as an example. However, those skilled in the art should understand that such position, matching relationship, etc. are also applicable to other components / other pairs of components.

[0043] The above description is merely an exemplary embodiment of the present invention and is not intended to limit the protection scope of the present invention. The protection scope of the present invention is determined by the appended claims.
