[0005] To achieve the above object, the utility model provides the following technical scheme:

[0006] A prevent falling structure under high speed vibration, including support seat, still including the sliding installation of slider on the support seat, the installation of connecting plate on the slider, the transmission installation of pawl shaft under the connecting plate, the pawl tooth of the rear end installation of pawl shaft, the installation of connecting rod between the front end of pawl shaft and the connecting plate, the installation of spring between the one end of connecting rod and the connecting plate, the uniform setting of a plurality of pawl grooves on the side close to the pawl tooth of support seat.

[0007] Further, the support seat is long rod shape, and is vertically arranged, to ensure the adjustment along the height direction.

[0008] Further, the pawl shaft and the connecting plate are connected by rolling bearing, to avoid the situation that the pawl shaft is not flexible in rotation caused by vibration impact force.

[0009] Further, the pawl groove and the support seat are integrally formed, to ensure the fixation of different heights.

[0010] Compared with the prior art, the beneficial effects are:

[0011] 1. The pawl tooth is inserted into the pawl slot through the setting, which ensures that it does not fall off under high-speed vibration, so that the test process is safer and more reliable;

[0012] 2. The pawl tooth is inserted into different pawl slots through the setting of the connecting rod, which realizes rapid height adjustment and reduces the workload of the operator;

[0013] 3. The pawl tooth is stably fixed in the pawl slot under the vibration through the setting of the spring applying a pre-tensioning force. BRIEF DESCRIPTION OF DRAWINGS
