[0047] When the adjustment block 233 moves, the support rod 25 is synchronously driven to move, wherein the lower end of the support rod 25 is rotatably connected to the outer surface of the base plate 28, so that when the adjustment block 233 moves, the support rod 25 is driven to rotate around the outer surface of the base plate 28, driving the positioning block 24 to move outward to support the lower end of the main body 1.

[0048] Furthermore, a first elastic member 261 is sleeved on the outer surface of the support column 26 , one end of the first elastic member 261 is connected to the telescopic rod 262 , and the other end is connected to the upper end of the ring 27 .

[0049] Specifically, the first elastic member 261 is an elastic member such as a spring, and the ring 27 is supported by the first elastic member 261. When the positioning block 24 is engaged with the main body 1, the rotating drum 21 is rotated to make the positioning rod 231 move along the inner wall of the arc groove 23, and at the same time drive the positioning block 24 to expand outward, thereby ensuring the stability of the connection of the main body 1.

[0050] Furthermore, the protection component 3 is assembled on the upper end of the positioning component 2, and the cables in the inner cavity of the cable tray are limited by the protection component 3.

[0052] Furthermore, an adjustment rod 34 is disposed at one end of the second elastic member 33 , and an end of the adjustment rod 34 passes through and extends to the other end of the fixing plate 32 .

[0053] Specifically, since the end of the second elastic member 33 is provided with the adjusting rod 34 , when the adjusting rod 34 moves, the adjusting rod 34 is supported by the second elastic member 33 , thereby ensuring that the adjusting rod 34 is always in a taut state.

[0054] Furthermore, a connecting plate 35 is slidably mounted on the lower end of the support plate 31, and the end of the connecting plate 35 is fixedly connected to the end of the adjusting rod 34.

[0055] Specifically, a slide groove is provided at the lower end of the support plate 31, and the inner wall of the slide groove is slidably connected to the outer surface of the upper end of the connecting plate 35. At the same time, the connecting plate 35 moves synchronously with the adjusting rod 34, and drives the limit block 36 rotatably installed on the connecting plate 35 to move. Since the end of the limit block 36 is rotatably connected to the middle position of the clamping plate 37, the clamping plate 37 is limited, and the opening and closing size of the end of the clamping plate 37 is controlled. The second elastic member 33 drives the clamping plate 37 to tightly protect the cable.

[0056] Furthermore, an adjusting member 38 is provided at one end of the fixing plate 32 of the clamping plate 37. The adjusting member 38 includes a fixing rod 381 connected to the clamping plate 37. The fixing rod 381 has an L-shaped cross section.

A clamping block 383 is rotatably mounted on the end of the fixing rod 381. A protective rod 384 is rotatably mounted on one end of the clamping block 383 away from the fixing rod 381. The lower end of the protective rod 384 is rotatably connected to the upper end of the flip rod 382. An arc plate 39 is provided at the end of the protective rod 384.

[0057] Specifically, the fixing rod 381 is connected to the clamping plate 37 to support the flip rod 382 and the clamping block 383.

[0059] When the positioning component 2 fixes the connection of the main body 1, the positions of the two positioning components 2 are adjusted through the guide groove 311 to make it suitable for the current scene, thereby fixing the connection of the main body 1. At the same time, when in use, by adjusting the distance between the two arc plates 39, the used cable is placed between the two arc plates 39, and the second elastic member 33 is used to press the arc plate 39 tightly against the cable. Through the support of the arc plate 39, the cable can be supported by the arc plate 39 at the turning point, thereby reducing the probability of cable damage and increasing the service life of the cable.
