[0025] As shown in FIGS. 3-4, the surface of the rotating roller 101 is provided with a limiting mechanism, the limiting mechanism includes an inclined tooth block 301, a check ring 302, a compression spring 303 and a matching block 304, the inclined tooth block 301 is installed on the outside of the wire reel 102, the check ring 302 is fixedly sleeved on the surface of the rotating roller 101, the compression spring 303 is movably sleeved on the surface of the rotating roller 101, one end of the compression spring 303 is fixedly connected to the inside of the check ring 302, and the matching block 304 is fixedly connected to the other end of the compression spring 303. The matching block 304 is connected with the inclined tooth block 301, and the matching block 304 is slidingly connected to the surface of the rotating roller 101.

Figure 2 The top surface of the threaded rod 202 is provided with a support plate 5, which is fixedly connected to the inner wall of the supporting leg 1. When the threaded rod 202 is rotating, the support plate 5 can assist in supporting the threaded rod 202 to prevent the threaded rod 202 from shaking due to excessive torque at the top end when rotating. Thus, the support plate 5 can assist in supporting and limiting the threaded rod 202, enabling the height adjustment mechanism to operate normally.

[0029] As shown in Figures 1-2, the supporting leg 1 is fixedly connected with a dust cover 6, and the servo motor 204 is located inside the dust cover 6. The dust cover 6 can effectively prevent dust and debris from entering the interior of the servo motor 204, maintaining the cleanliness of the interior of the servo motor 204 and preventing these impurities from affecting the normal operation of the servo motor 204, thereby effectively prolonging the service life of the servo motor 204.

[0030] The working principle of the utility model is as follows: when the wire laying device is used and needs to be adjusted in height, the servo motor 204 can be operated. The operation of the servo motor 204 drives the output rod 205 and the output wheel 203 to rotate simultaneously. The rotation of the output wheel 203 drives the meshed bevel gear 206 to rotate. The rotation of the bevel gear 206 drives the threaded rod 202 to rotate. The rotation of the threaded rod 202 rotates inside the base 201 and moves upward stably inside the base 201. The upward rotation of the threaded rod 202 drives the supporting leg 1 to move upward. The upward movement of the supporting leg 1 drives the rotating roller 101 and the wire reel 102 to move upward. Thus, the height of the supporting leg 1 can be adjusted to automatically adjust the overall height of the wire laying device main body. This not only enhances the applicability of the wire laying device, but also reduces manual operation and saves labor costs.

[0031] The above merely describes preferred embodiments of the present application, and it should be noted that, for those skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should also be considered as the protection scope of the present application.
