It can be understood that the foregoing scheme can improve the safety of the cable wire laying.

[0022] In the present embodiment, a plurality of universal self-locking wheels 102 are installed at the bottom of the base plate 101, and the plurality of universal self-locking wheels 102 facilitate the movement of the device.

[0023] The mounting plate 103 is fixed on the bottom plate 101, the matching piece 104 is annularly arranged in the through hole of the mounting plate 103, a plurality of the matching pieces 104 are annularly arranged and have a horn-shaped structure on the two sides, the rolling ball 105 is arranged in a line interval on the matching piece 104, the fixing piece 106 is integrally formed with the matching piece 104 and is fixedly connected with the mounting plate 103, and the limiting device is arranged on the bottom plate 101 and is located on the side of the bottom plate 101 close to the matching piece 104. The mounting plate 103 is fixed on the bottom plate 101 by bolts, the mounting plate 103 is provided with a circular through hole, the matching piece 104 is provided with the rolling ball 105 arranged in a line interval, the matching piece 104 is further integrally provided with the fixing piece 106, the fixing piece 106 is provided with a mounting hole for facilitating fixation by bolts, the matching pieces 104 are annularly arranged at intervals, the gap between the matching pieces 104 is appropriate, the cable is prevented from being clamped and stuck, and the limiting device is used for cable winding.

[0024] Secondly, the counterweight 107 is further fixedly installed on the bottom plate 101, the purpose of the counterweight 107 is to ensure the balance of the equipment after the cable winding is arranged, and the equipment is prevented from toppling, and the counterweight 107 will not affect the cable winding.

[0025] Then, the vertical plate 108 is fixed on the bottom plate 101, the wire winding drum 109 is rotatably installed on the vertical plate 108, and the locking assembly is arranged on one side of the wire winding drum 109. The vertical plate 108 is fixed on the bottom plate 101 by bolts, the mounting shaft end of the wire winding drum 109 is installed on the vertical plate 108 through a rotating bearing, one side of the wire winding drum 109 close to the vertical plate 108 is provided with a limiting portion for limiting one side of the cable winding, and the locking assembly is used for limiting the other side of the cable winding.

[0026] Finally, the abutting piece 110 is sleeved and installed on the stepped end of the wire winding drum 109 away from the vertical plate 108, and the rotating disc 111 is threadedly connected with the wire winding drum 109 and is located outside the abutting piece 110.

[0027] To address the problem that existing cable laying equipment has an overly simple conduit structure, and that cable sheathing is easily damaged during stretching when the cable is at an angle to the conduit, thus hindering safe wiring, this invention addresses the issue by using several universal self-locking wheels 102 for movement and locking. The cable reel is then fitted onto the reel 109, followed by the abutment plate 110 and the turntable 111, securing the cable reel and preventing it from falling off. Furthermore, the cable end is inserted into a circular cavity formed by a ring array of mating plates 104. As the cable passes through, the multiple mating plates 104... The rolling ball 105 can directly contact the cable surface for support. Furthermore, the several mating pieces 104 are arranged in a ring and have a flared structure on both sides. This structure prevents the cable from contacting the outer edge of the mating piece 104 when it is at an angle. The corresponding edges of the flared structure are rounded to avoid damage to the cable sheath when it is at an angle. The rolling ball 105 will make it easier to pull the cable, thus solving the problem that the existing cable laying equipment has an overly simple conduit structure, which easily causes damage to the cable sheath during the stretching process when the cable is at an angle to the conduit, which is not conducive to safe wiring.
