Two universal wheels 3 are respectively arranged at the bottoms of the left support plate 1 and the right support plate 2, which facilitates the easy and flexible movement of the winding drum a to be lifted and supported, and is convenient to use; a width adjustment component is arranged between the front sides of the left support plate 1 and the right support plate 2. Through the width adjustment component, the distance between the left support plate 1 and the right support plate 2 can be conveniently adjusted to be suitable for different models of winding drums a, and it is not restricted by the use site, with a wide application range and strong practicability; a lifting and supporting component is arranged between the middle parts of the left support plate 1 and the right support plate 2. The lifting and supporting component includes a hydraulic jack 7, a pressure rod 8, a sleeve 9, a connecting arm 10, a clamping seat 11, a movable shaft 12, and a guiding structure. Hydraulic jacks 7 are respectively arranged in the middle parts of the left support plate 1 and the right support plate 2. The lifting handle ends of the hydraulic jacks 7 are respectively connected with pressure rods 8, and sleeves 9 are respectively arranged at the ends of the pressure rods 8. A connecting arm 10 is fixedly connected inside one of the sleeves 9, and the connecting arm 10 is movably sleeved with the other sleeve 9.

It is not only safe and convenient to use, but also helps to save manpower.

[0030] Furthermore, referring to Figure 2 , Figure 5 and Figure 6 , the lifting and supporting component further includes a guide sleeve 15, a clamping block 16, a reset member 17, and a limiting ring 121. A guide sleeve 15 is arranged on the clamping seat 11, and a guide groove 111 communicated with the guide sleeve 15 is opened on the clamping seat 11. A clamping block 16 is slidably connected between the guide groove 111 and the guide sleeve 15, which is used to limit the movable shaft 12 clamped on the clamping seat 11, and can effectively avoid the situation that the movable shaft 12 for installing the winding drum a jumps or falls off during use, so that the communication cable b can be smoothly transported and installed; a reset member 17 is connected between one end of the clamping block 16 and the guide sleeve 15. The reset member 17 is a compression spring, which is used to provide a pressing force for the clamping block 16. Since the upper end of the clamping block 16 is designed with an inclined surface structure, when the clamping seat 11 drives the clamping block 16 thereon to move upward, when the inclined surface end of the clamping block 16 contacts the movable shaft 12, the clamping block 16 can be adaptively clamped on the movable shaft 12, thereby achieving the purpose of limiting the movable shaft 12. Two limiting rings 121 adapted to the clamping seat 11 are arranged on the movable shaft 12. By clamping the two limiting rings 121 on both sides of the clamping seat 11, the lateral movement of the movable shaft 12 can be restricted, which is beneficial to further improving the stability of the movable shaft 12 and the winding drum a during use.

[0031] Furthermore, referring to Figures 1 to 5 , the width adjustment assembly includes a slide rail 4, an adjustment plate 5, a limit rod 6 and an elastic member 60.

An elastic member 60 is connected between the upper part of the limit rod 6 and the slide rail 4. The elastic member 60 is a tension spring for providing a downward tension force to the limit rod 6 so that the lower end of the limit rod 6 can be stably inserted into the positioning hole 50. The limit rod 6 is designed in an n-shaped structure, so that one end of the n-shaped limit rod 6 can be inserted into the positioning hole 50 of the adjustment plate 5, and the other end can be inserted into the slide rail 4, thereby achieving the purpose of stably and conveniently fixedly connecting the left support plate 1 and the right support plate 2 after adjusting the spacing; an observation hole 40 is provided on the slide rail 4 for assisting in checking the insertion state of the limit rod 6 into the positioning hole 50, which is convenient for quickly inserting one end of the limit rod 6 into the corresponding positioning hole 50.

Through the auxiliary action of the guide rail 13 and the connecting block 14, the purpose of stably guiding the vertically lifted or lowered clamping seat 11 can be achieved.

[0033] When it is necessary to move the winding drum a wound with the communication cable b, the distance between the left support plate 1 and the right support plate 2 can be adjusted accordingly according to the length of the winding drum a, so that the extended left support plate 1 and right support plate 2 can be located on both sides of the winding drum a. Through the connection and cooperation of the limit rod 6 and the elastic member 60, the adjustment plate 5 and the slide rail 4 can be locked and fixed together. Then, the movable shaft 12 is sleeved on the winding drum a, and by pressing the connecting arm 10 up and down, the piston rod on the hydraulic jack 7 can drive the clamping seat 11 to lift upward, so that both ends of the movable shaft 12 can be clamped on the clamping seat 11 and lift the winding drum a synchronously upward. In this way, the purpose of flexibly lifting and moving different types of winding drums a can be achieved, with a wide range of applications, and a single person can easily complete the operation, which is safe and convenient to use; through the cooperation of the guide sleeve 15, the clamping block 16 and the reset member 17, the purpose of blocking and limiting the movable shaft 12 clamped on the clamping seat 11 can be achieved, thereby effectively avoiding the situation that the movable shaft 12 jumps or falls off during use.
