[0005] A pressing sheet is arranged in the annular cavity, and the pressing sheet is connected to the screw end of the fastening bolt.

[0006] A hanging buckle is installed on the connecting ring.

[0007] The elastic connecting piece is a spring wire.

[0008] The elastic bracelet comprises a connecting portion connected to the elastic connecting piece, and the connecting portion is connected to a tightening portion made of an elastic band.

[0009] The number of the fixing rings is greater than or equal to 2.

[0010] The utility model has the following beneficial effects:

[0011] 1. The first end of the elastic connector is connected to an elastic wristband, and the second end of the elastic connector is installed with a fixing ring through the connecting ring. The fixing ring is provided with an annular cavity for fitting the tool handle. When working, after the tool handle is placed in the annular cavity, the tool handle can be tightened and locked by manually tightening the fastening bolts installed on the side wall of the fixing ring. The elastic wristband is put on the wrist of the worker, thereby effectively avoiding the safety risk caused by the tool falling out of the hand.

[0012] 2. Through the setting of the hook, the tools with openings can be quickly connected.

[0013] 3. The setting of the tightening part made of elastic band can reduce the discomfort of the staff when wearing it, and can be suitable for wearing on wrists of different thicknesses.

[0014] 4. The setting of the spring wire can achieve a better buffering effect. On the one hand, it can reduce the impact on the hands of workers when the tools fall out of their hands. On the other hand, it can buffer the fall of the tools after they fall out of their hands, thus achieving further protection. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The embodiments of the present utility model are further described below in conjunction with the accompanying drawings.

[0020] See attached Figure 1-2 A general tool slip-off protection component for a hydropower plant includes an elastic connector 1, a first end of the elastic connector 1 is connected to an elastic wristband 2, a second end of the elastic connector 1 is connected to a connecting ring 3, a fixing ring 4 is installed on the connecting ring 3, a fastening bolt 5 is installed on the side wall of the fixing ring 4, and the screw of the fastening bolt 5 extends to the annular cavity 4a of the fixing ring 4.

[0021] The first end of the elastic connector 1 of the present application is connected to an elastic bracelet 2, and the second end of the elastic connector 1 is installed with a fixing ring 4 through a connecting ring 3. The fixing ring 4 is provided with an annular cavity 4a for fitting a tool handle. During work, after the tool handle is placed in the annular cavity 4a, the tool handle can be tightened and locked by manually tightening the fastening bolts 5 installed on the side wall of the fixing ring 4. The elastic bracelet 2 is put on the wrist of the worker, thereby effectively avoiding the safety risks caused by the tool falling out of the hand.
