Therefore, the length of the power cord is required to be adapted to the travel distance of the laying trolley, and thus the length of the power cord is quite long. In the same way, the length of the pulley guide rail is required to be matched with the running travel of the cloth laying trolley, so that the length of the pulley guide rail is quite long.

Detailed Description
In order to make the technical spirit and advantages of the present invention more clearly understood, the applicant will now make a detailed description by way of example, but the description of the examples is not intended to limit the scope of the invention, and any equivalent transformation made merely in form, not essentially, according to the inventive concept should be regarded as the scope of the technical solution of the present invention.
In the following description, any terms related to the directions or azimuths of up, down, left, right, front and rear are used in the positional state shown in fig. 1 unless otherwise stated, and thus should not be construed as a limitation on the technical solution provided by the present invention. For example: the position shown in fig. 3 is exactly opposite to the position shown in fig. 1, for the purpose of conveniently and clearly revealing the structure of the trolley rail extension attachment mechanism 6.
Example 1:
referring to fig. 1 in combination with fig. 3, a hanger bracket 1 is shown, which hanger bracket 1 is fixed in use with a frame 8 of a spreading machine, more precisely with a table foot of the frame 8 of the spreading machine, i.e. a spreading table foot, by hanger bracket fixing screws 12, the hanger bracket 1 being fixed with a table foot of the frame 8 of the spreading machine if the invention is applied to a spreading machine.
