[0030] 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 in conjunction with the accompanying drawings.

[0031] The utility model provides Figure 1-Figure 10A cable laying arm shown in the figure comprises: a main arm 1, one end of the main arm 1 is rotatably connected to the bottom of the auxiliary arm 2, a cable is arranged above the main arm 1 and the auxiliary arm 2, the top cross section is L-shaped, the end face is a circular structure, the top left and right sides of the main arm 1 are fixedly connected to the vertical plates 3, and the vertical plates 3 are provided with hand grooves 4 on the far sides; a steering assembly, the steering assembly comprises a plurality of steering plates 5 arranged at the bottom of the other end of the main arm 1, the top between every two steering plates 5 and the top of the steering plate 5 farthest from the main arm 1 are provided with a connecting plate 6, The steering plate 5 near the main arm 1 is rotatably connected to the bottom of one end of the main arm 1, and all steering plates 5 are connected to adjacent connecting plates 6 through a connecting structure, which includes a stepped groove 7 provided on the steering plate 5 and a slot 8 on the connecting plate 6, a semi-threaded bolt 9 is inserted into the slot 8, and a nut 10 is threadedly connected to the outer side of one end of the semi-threaded bolt 9, a torsion spring 11 is provided in the stepped groove 7, and the torsion spring 11 is sleeved on the outer side of the adjacent semi-threaded bolt 9, and the two ends of the torsion spring 11 are fixedly connected to the outer wall of the semi-threaded bolt 9 and the inner wall of the stepped groove 7 respectively;The fixing assembly includes a pressing sleeve 12 rotatably connected to one side of the top of the steering plate 5, a movable groove 13 is provided on the pressing sleeve 12, and a bayonet 14 is movably connected in the movable groove 13. The fixing assembly also includes a through groove 15 opened on one side of the middle of the top of the steering plate 5, and an extrusion groove 16 is provided at the bottom of the through groove 15. The same vertical groove 17 is provided on the same side of the through groove 15 and the extrusion groove 16. The auxiliary force arm 2 is used to extend the length of the main force arm 1 when needed, and the hand groove 4 is used to facilitate the user to pull the main force arm 1. The steering plate 5 is provided with multiple groups, which can be convenient for adaptive rotation according to the actual turning situation to change the turning radius of the laying force arm as a whole. The stepped groove 7 is used to accommodate the torsion spring 11 and allow the semi-threaded bolt 9 to pass through. The torsion spring 11 is used to reset the steering plate 5 when it is not bent by external force, and no manual reset is required. The pressing sleeve 12 is used to fix the cable, the movable groove 13 and the through groove 15 are used to move the bayonet 14, the extrusion groove 16 can limit the bayonet 14, and the vertical groove 17 can facilitate the bayonet 14 to move up and down. When in use, first place the cable above a plurality of steering plates 5, turn the compression sleeve 12 in sequence to make one end of it close to the adjacent steering plate 5, then press the bayonet pin 14 to make it move to the bottom in the vertical slot 17, then move the bayonet pin 14 horizontally to make its upper part pass through the moving slot 13 and the through slot 15 respectively, and the lower part squeezes the squeezing slot 16 to deform and stretch it open until it enters the right end. At this time, since the opening radius of the through slot 15 is smaller than the maximum outer diameter of the bayonet pin 14, the bayonet pin 14 cannot be pulled out upwards, so as to fix the compression sleeve 12 at this place. When the compression sleeve 12 is fixed, the inner surface of its top will generate an inward squeezing force on the outside of the cable to ensure that it is fixed on the steering plate 5. When moving, the user can push the main arm 1 or the auxiliary arm 2 forward to drive the cable to move. When moving, it can move close to one side, so that the front steering plate 5 and the connecting plate 6 can contact the wall more quickly, and then the steering plate 5 and the connecting plate 6 can rotate relative to each other under the action of the thrust and squeezing force, and the arc and radius of the moving direction are changed to adapt to the turning radius at this place. ;

[0032] Furthermore, a notch 19 is provided on one end of the main arm 1 close to the auxiliary arm 2, and a protrusion 20 is fixedly connected to the top end of the auxiliary arm 2. The notch 19 and the protrusion 20 cooperate to limit the rotation of the auxiliary arm 2 and fix its rotation angle, thereby ensuring stability when pushing the auxiliary arm 2.

[0033] Furthermore, a limit baffle 18 is fixedly connected to the top of the steering plate 5 farthest from the main arm 1. The limit baffle 18 is an arch-shaped structure. The limit baffle 18 can locate and limit the position when installing the cable, thereby improving the reliability and stability of the connection between the arm and the cable.

[0034] Furthermore, the connecting plate 6 is dumbbell-shaped, and the thickness of the connecting plate 6 is the same as that of the main arm 1. Limiting the shape of the connecting plate 6 can reduce the amount of material used, while facilitating its rotation relative to the main arm 1 for easy operation.

[0035] Furthermore, the bottom of the bayonet 14 is fixedly connected to a limit block, and the top of the bayonet 14 is fixedly connected to a ball head. The limit block can limit the position of the bayonet 14 in the groove, and the ball head can facilitate the movement of the bayonet 14.

[0036] Furthermore, the outer diameter of the limit block is larger than the circumferential radius of the bayonet 14 , and the outer diameter of the vertical slot 17 matches the outer diameter of the limit block. The limited outer diameter can facilitate the limit block to move up and down in the vertical slot 17 and fix the bayonet 14 .

[0037] Furthermore, the inner diameter of the right end of the extrusion groove 16 is adapted to the outer diameter of the limit block, and the outer diameter of the middle section of the extrusion groove 16 is smaller than the inner diameter of the right end above the right end. The inner diameter of the extrusion groove 16 can be limited to limit its horizontal movement after the limit block reaches the right end of the extrusion groove 16, making it difficult for it to move in the extrusion groove 16 without the action of strong external force, thereby ensuring the stability of the force arm during laying.

[0038] The above only describes some exemplary embodiments of the present invention by way of illustration. 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.
