[0017] Please refer to Figures 1-4, the present utility model provides the following technical solutions: It includes a box body 1 and a base 2. A plurality of heat dissipation holes 11 are opened at the bottom of the box body 1, and a plurality of through grooves 12 are opened at the bottom of the inner cavity of the box body 1. A plurality of cable limiting grooves 13 are opened at one end of the bottom of the box body 1. A connection cavity 21 is opened inside the base 2, and sand grains 22 are provided at the bottom of the base 2. A rubber pad 23 is provided inside the connection cavity 21. Both sides of the box body 1 are detachably connected with connection plates 3. A plurality of wiring holes 31 are opened on one side of the connection plate 3. A cleaning housing 32 is provided inside the wiring hole 31. A telescopic rod 4 is provided inside the through groove 12. Two ends of the telescopic rod 4 are respectively fixedly connected with the bottom of the box body 1 and the top of the base 2. A connection spring 41 is provided outside the telescopic rod 4, and a limiting plate 42 is provided at the top of the telescopic rod 4.

[0018] In this implementation: This new type consists of a box body 1 and a base 2 to form an external overall structure. A number of heat dissipation holes 11 are opened at the bottom of the box body 1 to enhance the heat dissipation effect at the bottom of the box body 1. And a number of through grooves 12 are opened at the bottom of the inner cavity of the box body 1. A telescopic rod 4 is arranged inside the through groove 12. The two ends of the telescopic rod 4 are fixedly connected to the bottom of the box body 1 and the top of the base 2 respectively. A connecting spring 41 is arranged outside the telescopic rod 4. And a limiting plate 42 is arranged at the top of the telescopic rod 4. The telescopic rod 4 and the connecting spring 41 connect the box body 1 and the base 2. The distance between the box body 1 and the base 2 is changed by the telescopic deformation of the telescopic rod 4. When the telescopic rod 4 extends, the distance between the box body 1 and the base 2 increases, so that one end of the heat dissipation hole 11 is no longer blocked by the base 2, thereby increasing the heat dissipation effect inside the box body 1 through the heat dissipation hole 11. A number of cable limiting grooves 13 are opened at one end of the bottom of the box body 1 to limit the position of the cable during wiring. A number of wiring holes 31 are opened on one side of the connecting plate 3. After the cable is limited by the cable limiting groove 13, it passes through the wiring hole 31. When used temporarily at the construction site, after the cable is drawn out from the inside of the box body 1, through the limitation of the cable limiting groove 13 and the wiring hole 31, multiple cables are evenly distributed, and there is a certain distance between each cable. Then the cable is connected to the external cable. When used temporarily at the construction site, the cable hangs down on the ground and will be covered with dust and dirt. When the cable is retracted into the inside of the box body 1 after the box body 1 is used up, it will bring dust and dirt into the inner cavity of the box body 1 together. Through the cleaning shell 32 arranged inside the wiring hole 31, since the inner diameter of the wiring hole 31 gradually becomes smaller from the outside to the inside, the cleaning shell 32 can remove the dust and dirt attached to the outside of the cable, thereby preventing dust and dirt from entering the inside of the box body 1. A connecting cavity 21 is opened inside the base 2, and sand grains 22 are arranged at the bottom of the base 2. A rubber pad 23 is arranged inside the connecting cavity 21. When used at the construction site, the ground may be uneven, resulting in the box body 1 not being stable enough when placed on the ground at the construction site, so that the box body 1 is prone to tipping over. Through the sand grains 22 and the rubber pad 23, when the bottom of the base 2 is on the uneven ground, through the extrusion of the protruding position on the rubber pad 23, the sand grains 22 are displaced inside the inner cavity of the connecting cavity 21 to make way for the protruding position, so that the bottom of the base 2 fits the uneven bottom surface, increasing the connection effect between the base 2 and the bottom surface and maintaining its stability. This enables this new type to limit the wiring of the connecting cable when used at the construction site. After the cable is used up, it can clean the dust, dirt, etc. on the surface of the cable before the cable enters the inside of the box body, avoiding the problem that it is not easy to clean after the cable brings dust, dirt, etc. into the inside of the box body and affecting the electrical components inside the box body, and can increase the stability of the box body 1 at the construction site, reducing the problem that the box body 1 is prone to tipping over during use.

[0019] Fixing parts 33 are provided at the four corners on one side of the connecting plate 3. The connecting plate 3 is fixedly installed with the box body 1 and the base 2 through the fixing parts 33. By providing the fixing parts 33, after the distance between the box body 1 and the base 2 increases, it is connected between the box body 1 and the base 2 to support them. At the same time, after the distance between the box body 1 and the base 2 increases, the wiring holes 31 on the connecting plate 3 are exactly aligned with one end of the cable limiting groove 13 to route the cables.

[0020] The limiting plate 42 is arranged in the inner cavity of the box body 1, and the diameter of the limiting plate 42 is larger than the aperture of the through groove 12. The through groove 12 and the cable limiting groove 13 are arranged in a staggered manner. By providing the limiting plate 42, one end of the telescopic rod 4 is limited to prevent it from separating from the box body 1 and maintain the connection effect between the telescopic rod 4 and the box body 1.

[0021] The cleaning housing 32 is fixedly connected to the inner wall of the wiring hole 31, and the inner diameter of the cleaning housing 32 gradually decreases from the outside to the inside. By setting the cleaning housing 32 to have a gradually decreasing diameter, when the cable is retracted, the dirt and dust on its surface can be cleaned up.

[0022] The connecting spring 41 is sleeved outside the telescopic rod 4. The diameter of the connecting spring 41 is smaller than the aperture of the through groove 12, and both ends of the connecting spring 41 are fixedly connected to the bottom of the box body 1 and the top of the base 2 respectively. The telescopic rod 4 and the connecting spring 41 connect the box body 1 and the base 2, and the distance between the box body 1 and the base 2 is changed by the telescopic deformation of the telescopic rod 4.

[0023] Working principle and usage process of the utility model: During use, when the ground at the construction site is uneven, when the box body 1 is placed on the ground at the construction site, it is not stable enough, resulting in the easy tipping of the box body 1. Through the sand grains 22 and the rubber pad 23, when the bottom of the base 2 is located on the uneven ground, the extrusion of the protruding position on the rubber pad 23 causes the sand grains 22 to displace inside the connecting cavity 21 to make way for the protruding position, so that the bottom of the base 2 fits with the uneven bottom surface, increasing the connection effect between the base 2 and the bottom surface and maintaining its stability. The distance between the box body 1 and the base 2 is changed by the telescopic deformation of the telescopic rod 4. When the telescopic rod 4 extends, the distance between the box body 1 and the base 2 increases, so that one end of the heat dissipation hole 11 is no longer blocked by the base 2, thereby increasing the heat dissipation effect inside the box body 1 through the heat dissipation hole 11. A number of cable limiting grooves 13 are provided at one end of the bottom of the box body 1 to limit the position of the cable during wiring. A number of wiring holes 31 are provided on one side of the connecting plate 3. After the cable is limited by the cable limiting groove 13, it passes through the wiring hole 31. When used temporarily at the construction site, after the cable is drawn out from the inside of the box body 1, through the limitation of the cable limiting groove 13 and the wiring hole 31, multiple cables are evenly distributed, and there is a certain distance between each cable. Then the cable is connected to the external cable. After use, since the inner diameter of the wiring hole 31 gradually decreases from the outside to the inside, the cleaning housing 32 can remove the dust and soil attached to the outside of the cable, thus preventing the dust and soil from entering the inside of the box body 1.
