[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] In the present invention, one end of the cable passes successively above the first roller, below the adjusting assembly, and below the pressing assembly, and then the end of the cable is fixed. Then, the laying device body is driven to move by the cooperation of the pull rod and the universal wheel. At this time, the cable reel pays out the cable. The tension of the cable is adjusted by the adjusting assembly to ensure that the laying end of the cable is always in a taut state, guaranteeing the stability of the cable during laying. Then, the pressing assembly presses the cable to always contact the laying surface, enabling the cable to be laid straight. Multiple groups of cables can be laid simultaneously, preventing the multiple groups of cables from being wound during laying and improving the laying efficiency of the cables.

[0024] The torsion spring drives the movable pressure rod to rotate towards the laying surface, causing the movable pressure rod to press the cable to ensure that the cable fits the laying surface. Multiple third rollers are arranged inside the pressing frame hinged to the fixed frame, and the positions of the third rollers correspond one by one to the positions of the first rollers, enabling the third rollers and the first rollers to cooperate to lay the cable straight. The top spring presses the top block against the pressing frame, thereby pressing down both ends of the pressing frame simultaneously to ensure that the pressing frame and the third rollers drive the cable to fit the laying surface.

[0025] When the handle is inserted into the middle adjustment slot and the adjustment handle is limited, at this time, the third spring presses the limit block into the first limit slot, thereby vertically limiting the movable bracket. And at this time, the traction rope is in a taut state. And at this time, the adjustment handle presses the end of the movable block close to the adjustment top block into the movable slot through the adjustment top block, and the other end of the movable block extends out of the card slot, and presses the linkage plate into the linkage slot. Thus, the linkage plate cooperates with the linkage block and the second limit slot to limit the slider. At this time, the movable bracket can neither move horizontally nor vertically.

[0026] When the handle is inserted into the lower adjustment slot and the adjustment handle is limited, the adjustment handle will move upward and drive the traction rope to move, causing the traction rope to pull the limit block into the limit top slot, thereby canceling the vertical limit on the movable bracket. Then, hold the adjustment handle through the finger slot to drive the limit sliders on both sides of the movable bracket to slide in the limit chute, thereby adjusting the vertical position of the movable bracket. At this time, the movable bracket cannot move horizontally. At this time, the vertical position of the movable bracket is adjusted to drive the second roller to press the cable, thereby adjusting the tension of the cable.

[0027] When the handle is inserted into the inner part of the adjusting slot at the upper end and the adjusting handle is limited, the adjusting handle will move downward and drive the traction rope to slacken. At this time, the third spring pushes the limiting block into the first limiting slot, thereby vertically limiting the movable bracket. At this time, the adjusting top block is separated from the movable block, and the first spring pushes the movable block to move towards the adjusting handle, so that the end of the movable block away from the adjusting handle is received into the limiting slider. At this time, the second spring pushes the linkage plate into the clamping slot, and the linkage plate drives the linkage block to disengage from the second limiting slot, thereby canceling the limit on the slider. Then, the adjusting handle can be held through the finger groove to drive the movable bracket and the slider to move horizontally along the sliding groove. When the movable bracket approaches the pressing component, the tension range of the cable can be adjusted to the maximum by vertically adjusting the position of the movable bracket. On the contrary, the tension range of the cable is adjusted to the minimum. Therefore, the tension suitable for cable laying can be adjusted according to the on-site needs, ensuring the cable laying efficiency and preventing multiple cables from being entangled.

A third elastic member is arranged between the limiting block 43 and the limiting top groove 41 for pushing one end of the limiting block 43 out of the limiting top groove 41. The second elastic member includes a third spring 42. One end of the third spring 42 is connected to the limiting top groove 41, and the other end is connected to the limiting block 43, and the third spring 42 is always in a compressed state.

[0053] The linkage member includes a pressing groove 28, an adjusting top block 25, a clamping groove 3001, a movable groove 26, a movable block 27, a traction groove 38 and a traction rope 39. The pressing groove 28 is opened on the movable bracket 8 and is located on both sides of the adjusting handle 22. The adjusting top block 25 is arranged at the position of the adjusting handle 22 corresponding to the pressing groove 28. The clamping groove 3001 is opened at the position of the limiting slider 30 corresponding to the linkage groove 34. The movable groove 26 penetrates through the pressing groove 28 and the clamping groove 3001. The movable block 27 is slidably arranged in the movable groove 26. A fourth elastic member is arranged between the movable block 27 and the movable groove 26. The traction groove 38 is opened on the adjusting handle 22. One end of the traction rope 39 is connected to the top of the traction groove 38, and the other end passes through the movable bracket 8 and penetrates into the limiting top groove 41 from the bottom of the groove and is connected to the limiting block 43. The fourth elastic member includes a first spring 31. One end of the first spring 31 is connected to the movable groove 26, and the other end is connected to the movable block 27, and the first spring 31 is always in a compressed state.

[0054] When the handle 33 is inserted into the middle adjusting groove 24 and limits the adjusting handle 22, at this time, the third spring 42 pushes the limiting block 43 into the first limiting groove 35, thereby vertically limiting the movable bracket 8. And at this time, the traction rope 39 is in a taut state. And at this time, the adjusting handle 22 presses the end of the movable block 27 close to the adjusting top block 25 into the movable groove 26 through the adjusting top block 25. The other end of the movable block 27 extends out of the clamping groove 3001, and presses the linkage plate 32 into the linkage groove 34. Thus, the linkage plate 32 cooperates with the second limiting groove 36 through the linkage block 37 to limit the slider 7. At this time, the movable bracket 8 can neither move horizontally nor vertically.

[0055] When the handle 33 is inserted into the adjusting groove 24 at the lower end and the adjusting handle 22 is limited, the adjusting handle 22 will move upward and drive the traction rope 39 to move, so that the traction rope 39 pulls the limit block 43 into the limit top groove 41, thereby canceling the vertical limit of the movable bracket 8, and then holds the adjusting handle 22 through the finger groove 23 to drive the limit sliders 30 on both sides of the movable bracket 8 to slide in the limit slide groove 29, so that the vertical position of the movable bracket 8 can be adjusted. At this time, the movable bracket 8 cannot move horizontally. At this time, the position of the movable bracket 8 is vertically adjusted to drive the second roller 10 to press the cable 4, thereby adjusting the tension of the cable 4.

[0056] When the handle 33 is inserted into the adjusting slot 24 at the upper end and the adjusting handle 22 is limited, the adjusting handle 22 will move downward and drive the traction rope 39 to relax. At this time, the third spring 42 pushes the limit block 43 to enter the first limit slot 35, thereby vertically limiting the movable bracket 8. At this time, the adjusting top block 25 is separated from the movable block 27, and the first spring 31 pushes the movable block 27 to move toward the adjusting handle 22, so that the movable block 27 is away from the end of the adjusting handle 22 and is received in the limit slider 30. At this time, the second spring 40 pushes the linkage plate 32 to enter the slot 30. 01, the linkage plate 32 drives the linkage block 37 to disengage from the second limit groove 36, thereby canceling the limit on the slider 7, and then the adjusting handle 22 can be held through the finger groove 23 to drive the movable bracket 8 and the slider 7 to move horizontally along the slide groove 6. When the movable bracket 8 is close to the pressing component, the position of the movable bracket 8 is vertically adjusted to adjust the tension range of the cable 4 to the maximum, and vice versa, the tension range of the cable 4 is adjusted to the minimum. Therefore, the tension of the cable 4 can be adjusted according to the on-site needs to ensure the laying efficiency of the cable 4 and prevent multiple cables 4 from being entangled.

[0057] The specific scheme is as follows: first, one end of the cable 4 is passed over the first roller 5, under the adjustment component and under the pressing component in sequence, and then the end of the cable 4 is fixed, and then the laying device body 1 is driven to move by the pull rod 102 and the universal wheel 101. At this time, the cable reel 3 releases the cable 4, and the tension of the cable 4 is adjusted by the adjustment component to ensure that the cable 4 will not detach from the first roller 5, thereby ensuring the stability of the laying of the cable 4. Then, the pressing component presses the cable 4 to always contact the laying surface, so that the cable 4 can be laid straight. After the laying device body 1 is moved to a certain distance, the cable 4 on the laying surface is intermittently fixed, so that multiple groups of cables 4 can be laid at the same time, preventing multiple groups of cables 4 from being entangled during laying, thereby improving the laying efficiency of the cable 4.

[0058] The torsion spring 12 drives the movable pressure rod 13 to rotate towards the laying surface, so that the movable pressure rod 13 presses the cable 4 to ensure that the cable 4 fits the laying surface. Through a plurality of third rollers 16 arranged inside the pressing frame 15 hinged to the fixed frame 14, and the positions of the third rollers 16 correspond to the positions of the first rollers 5 one by one, so that the third rollers 16 and the first rollers 5 cooperate to lay the cable 4 straight. The top spring 19 presses the top block 20 to contact the pressing frame 15, thereby pressing down both ends of the pressing frame 15 simultaneously to ensure that the pressing frame 15 and the third rollers 16 drive the cable 4 to fit the laying surface.

[0059] When the handle 33 is inserted into the middle adjustment groove 24 and limits the adjustment handle 22, at this time the third spring 42 presses the limit block 43 into the first limit groove 35, thereby vertically limiting the movable bracket 8, and at this time the traction rope 39 is in a taut state, and at this time the adjustment handle 22 presses the end of the movable block 27 close to the adjustment top block 25 into the movable groove 26 through the adjustment top block 25. The other end of the movable block 27 extends out of the card slot 3001, and the linkage plate 32 is pressed into the linkage groove 34, so that the linkage plate 32 cooperates with the linkage block 37 and the second limit groove 36 to limit the slider 7. At this time, the movable bracket 8 can neither move horizontally nor vertically.

[0060] When the handle 33 is inserted into the lower adjustment groove 24 and limits the adjustment handle 22, the adjustment handle 22 will move upward and drive the traction rope 39 to move, so that the traction rope 39 pulls the limit block 43 into the limit top groove 41, thereby canceling the vertical limit of the movable bracket 8. Then, hold the adjustment handle 22 through the finger groove 23 to drive the limit sliders 30 on both sides of the movable bracket 8 to slide in the limit sliding groove 29, so that the vertical position of the movable bracket 8 can be adjusted. At this time, the movable bracket 8 cannot move horizontally. At this time, by vertically adjusting the position of the movable bracket 8, the second roller 10 is driven to press the cable 4, thereby adjusting the tension of the cable 4.

[0061] When the handle 33 is inserted into the internal adjustment slot 24 at the upper end and limits the adjustment handle 22, the adjustment handle 22 will move downward and drive the traction rope 39 to slack. At this time, the third spring 42 pushes the limit block 43 into the first limit slot 35, so as to vertically limit the movable bracket 8. At this time, the adjustment top block 25 is separated from the movable block 27, and the first spring 31 pushes the movable block 27 to move towards the adjustment handle 22, so that the end of the movable block 27 away from the adjustment handle 22 is received into the limit slider 30. At this time, the second spring 40 pushes the linkage plate 32 into the card slot 3001, and the linkage plate 32 drives the linkage block 37 to disengage from the second limit slot 36, thereby canceling the limit on the slider 7. Then, the adjustment handle 22 can be held through the finger slot 23 to drive the movable bracket 8 and the slider 7 to move horizontally along the chute 6. When the movable bracket 8 approaches the pressing assembly, the tension range of the cable 4 can be adjusted to the maximum by vertically adjusting the position of the movable bracket 8. On the contrary, the tension range of the cable 4 is the smallest. Therefore, the tension suitable for the cable 4 laying can be adjusted according to the on-site needs, ensuring the laying efficiency of the cable 4 and preventing multiple cables 4 from being entangled.

The scope of the present invention is defined by the appended claims and their equivalents.
