The utility model relates to the technical field of side slope treatment, in particular to a vegetation cell fixing device which is used for fixing vegetation cells and comprises anchor rod pieces and supporting pieces. The supporting piece is of a three-dimensional supporting structure with a certain width and is at least suitable for supporting one inner wall of the plant-growing grid chamber, and the contact face of the supporting piece and the inner wall of the plant-growing grid chamber is a supporting face. The anchor rod piece comprises a rod part, and the rod part is provided with a sharp end used for being embedded into a geological base and a dull end. The supporting piece is fixed to the dull end of at least one anchor rod piece. In the embodiment of the invention, the support pieces with certain widths are fixed with the vegetation cells, so that the contact area is increased, the stress pressure of the cells is reduced, the cells can be well fixed, and the vegetation cells can be fixed more firmly, so that the vegetation cells can adapt to steeper slopes, the hanging stability of the vegetation cells can be effectively improved, and the service life of the vegetation cells is prolonged. And the service life of the vegetation grid chamber can be prolonged, and the maintenance and repair frequency and the maintenance cost are greatly reduced.

This utility model relates to the field of medical assistance technology and discloses a detachable stretcher bed for restraining mental patients. It includes a stretcher and a bed frame. Casters are installed at the bottom of the bed frame, and a mattress is placed on the stretcher. The stretcher slides on the bed frame, and a moving mechanism is installed on the bed frame to drive the stretcher to move along the width and height of the bed frame. A support unit is installed at the bottom of the stretcher to provide support for the stretcher after it has slid along the bed frame. Several restraint units are hidden on both sides of the stretcher along its length. The moving mechanism drives the stretcher to slide along the bed frame, allowing staff to quickly separate the stretcher from the bed frame. The hidden restraint units on both sides of the stretcher can effectively restrain the patient when needed while avoiding discomfort caused by the patient seeing the restraints. The restraint units reduce the risk of injury to staff and staff during patient stress, and the detachable nature of the stretcher prevents inhumane practices such as carrying patients later.

The utility model relates to the field of protection devices, in particular to a cable bending tightness limiting protection device which comprises a first bending track, a limiting assembly and a pressing assembly. The two ends of the first bending track are respectively provided with a limiting assembly used for adjusting, limiting and fixing according to the size condition of a cable, and the inner side of the first bending track is provided with a plurality of pressing assemblies used for pressing and fixing the position of the cable. According to the utility model, the cable is bent and laid along the first bending track, then the second bending track on the first bending track is taken up to be assembled with the cable, then the limiting assembly is adjusted to be limited and fixed according to the size of the cable, and then the pressing assembly moves downwards to press, fix and protect the cable. By means of the adjustable limiting structure, the function of pressing cables with different diameters can be achieved, the cables with different specifications can be conveniently restrained, the cables are arranged in order, the cables can be prevented from being damaged due to excessive bending, and the performance and the service life of the cables are maintained.

The application provides a construction site building material transfer device and relates to the technical field of building material transfer. The application discloses a construction site building material transfer device, which relates to the technical field of building material transfer and comprises a fixing part, a stabilizing part, a supporting material part and a discharging part. The supporting material part is arranged above the fixing part, and the discharging part is arranged below the supporting material part. The supporting material frame is inserted into the supporting frame, and is kept stable under the action of the clamping blocks. The locking frame is used for restraining the pipe material. The restraining plate is inserted into the locking frame, and is kept stable while restraining the locking frame. The restraining plate supports and restrains the pipe material, and keeps the pipe material stable during transportation. The pipe material is prevented from rolling due to external force. The pipe material is directly loaded onto the transfer vehicle during transfer, rolls in the vehicle body during transfer due to vibration, and affects the moving vehicle body. The application solves the problem that the pipe material directly rolls in the vehicle body during transfer due to vibration.
