[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] This kind of wrench is used to lift and lower the guardrail. By setting up the guardrail mechanism, when the position of the guardrail needs to be adjusted, the upper support rod, the middle support rod and the bottom support rod are inserted into each other. Since the wrench is movably connected with a pull rod through a support pin shaft, and a push rod 1 is rotatably connected inside the lower surface of the pull rod, a push rod spring is sleeved on the outer surface of the push rod 1. The lower end outer surface of the push rod 1 passes through a guiding baffle plate connected inside the upper support rod, and a plug plate 1 is fixedly connected to the lower end of the push rod 1. The plug plate 1 is clamped on the outer surface of a telescopic pin shaft 1 arranged inside the upper support rod. The telescopic pin shaft 1 is inserted into a notch 1 opened at the overlapping part of the upper support rod and the middle support rod. At the same time, a housing is arranged inside the middle support rod, a connecting seat is fixedly connected inside the housing, and a push rod 2 is movably connected inside the connecting seat. A spring 2 is sleeved on the outer surface of the push rod 2. At the same time, a plug plate 2 is fixedly connected to the lower end of the push rod 2. The inside of the plug plate 2 is inserted into the outer surface of a telescopic pin shaft 2. The telescopic pin shaft 2 is inserted into a notch 2 opened at the overlapping part of the middle support rod and the bottom support rod. When the guardrail needs to move downward, by pushing one end of the telescopic pin shaft 1, the spring 1 inside the telescopic pin shaft 1 is compressed, and the wrench is lifted upward. The wrench drives the pull rod to move downward through the support pin shaft, and the pull rod pushes the push rod 1 to move downward, while squeezing the push rod spring. The plug plate 1 connected to the lower end of the push rod 1 moves downward synchronously and abuts against the push rod 2. At this time, the telescopic pin shaft 2 is pushed, and the spring 3 arranged inside the telescopic pin shaft 2 is compressed. The plug plate 1 abutting against the push rod 2 pushes the push rod 2 to move downward, and the spring 2 sleeved on the outer surface of the push rod 2 is squeezed. At this time, the plug plate 2 arranged at the lower end of the push rod 2 moves downward, so that the upper support rod slides into the inside of the middle support rod, and the middle support rod slides into the inside of the bottom support rod. At this time, it is convenient for patients to get on and off the bed. Press the wrench downward. At this time, under the elastic action of the push rod spring, spring 1, spring 2 and spring 3, the telescopic pin shaft 2 is inserted into the notch 2, and the telescopic pin shaft 1 is inserted into the notch 1, so as to expand the guardrail as a whole upward, thus playing a role in protecting the patient. The setting of this structure can effectively adjust the guardrail up and down. It plays a protective role when adjusted upward and plays a role in facilitating patients to get on and off the bed when adjusted downward, improving the practicability of the guardrail. This structure is based on a principle similar to that of a lever, saving effort and facilitating operation by personnel, and improving the convenience of its operation.
