Subtracting that tool to lock was used plays noise reducing device

Subtracting that tool to lock was used plays noise reducing device, including the oil hydraulic cylinder as buffer of axial device on lock panel, with connector that the piston rod of oil hydraulic cylinder is connected, and the spacing conveying frame of handle be connected with the connector, the spacing conveying of handle frame device still is equipped with handle reset spring on the handle onthe tool to lock handle, reset spring returns when reseing under the spring action powerful, conveys the piston rod with the resilience force and reduces the connector through the oil pressure resistance in the oil hydraulic cylinder and the speed of the spacing conveying of handle frame reversion and make the resilience force receive to alleviate through the spacing conveying frame of handle, connector. The utility model discloses the powerful resilience force that can effectively utilize the oil pressure resistance buffer spring of oil hydraulic cylinder makes slowly return of reset springto noise abatement, the no
