[0022] The above design, by providing the fixing seat 33, the fixing assembly 5 and the fixing rod 41, can fix the holder 4 by inserting the fixing rod 41 into the through hole 331, thereby improving the efficiency of disassembly and installation and facilitating transportation.

[0023] See also Figure 3-Figure 5 The fixing assembly 5 includes a fixing tooth 51 and a slider 52. The through groove 332 is provided with a slide groove 333 corresponding to the slider 52. The slider 52 is fixedly mounted on the outer wall of the fixing tooth 51. The slider 52 is slidably connected in the slide groove 333. The outer wall of the fixing rod 41 is provided with a fixing groove 411 that cooperates with the fixing tooth 51. By setting the fixing tooth 51, the slider 52, the slide groove 333 and the fixing groove 411, the fixing tooth 51 can be snapped into the fixing groove 411, so that the fixing rod 41 is snapped into the through hole 331, thereby achieving fixation. The left end face of the fixed tooth 51 is provided with an arc surface 511. By providing the arc surface 511, when the fixing rod 41 rotates clockwise, the fixed groove 411 can push the fixed tooth 51 to withdraw through the guidance of the arc surface 511, so that the fixed tooth 51 is retracted into the through groove 332, and the fixing rod 41 is unlocked, thereby facilitating disassembly. The outer wall of the slider 52 is provided with a tension spring 334, and the other end of the tension spring 334 is fixedly connected to the slide groove 333.

[0024] Based on the above embodiment 1, please refer to Figure 3-Figure 5 The rear end face of the fixing rod 41 is provided with an inclined surface 412. By providing the inclined surface 412, when the fixing rod 41 passes through the through hole 331, the fixing rod 41 can push the fixing tooth 51 to retreat into the through hole through the guidance of the inclined surface 412, thereby facilitating the fixing rod 41 to pass through the through hole 331. The fixing rod 41 is cylindrical. By providing the cylindrical fixing rod 41, it can be easily rotated, and by rotating, it is convenient to take out the rock block in the holder 4.

[0025] The working principle and use process of this utility model:

[0026] During installation, hold the holder 4 and insert the fixing rod 41 into the through hole 331. When the fixing rod 41 contacts the fixing tooth 51, the inclined surface 412 of the fixing rod 41 can guide the fixing rod 41 to push the fixing tooth 51 into the through hole. At this time, the fixing tooth 51 drives the slider 52 to slide and stretches the tension spring 334. As the fixing rod 41 is fully extended into and passes through the through hole, the fixing tooth 51 contacts the fixing groove 411. At this time, the tension spring 334 retracts and resets the fixing tooth 51. When the fixing tooth 51 is stuck in the fixing groove 411, the installation is completed. When it is necessary to remove the rock block in the holder 4, rotate the holder 4 clockwise. Due to the left end surface of the holder 4 It is provided with an arc surface 511. When the fixing rod 41 rotates clockwise, the fixing rod 41 can be easily rotated through the guidance of the arc surface 511, so that the open end of the holder 4 is tilted downward, which facilitates the sliding of the rock block. When disassembling, the holder 4 is rotated clockwise, and the holder 4 drives the fixing rod 41 to rotate. At this time, the fixing groove 411 is guided by the arc surface 511 of the fixing tooth 51, and the fixing groove 411 is pushed back into the through groove 332. At this time, the slider 52 stretches the tension spring 334. When the fixing tooth 51 is disengaged from the fixing groove 411, the holder 4 is dragged to disengage the fixing rod 41 from the through hole 331 to complete the disassembly. When the fixing rod 41 is disengaged from the through hole 331, the tension spring 334 resets the fixing tooth 51.
