Problems solved by technology

[0004] In order to save costs, the spring over-center operating mechanism without a design of a relief slot on the main shaft is more dangerous to the operator.
At the same time, for the case where a relief block is provided on the main shaft, if each phase of the spring overrunning operating mechanism has two relief blocks, it will increase the number of components and increase the cost

Abstract

The invention discloses a spring over-centering operating mechanism and an operating handle thereof used for the spring over-centering operating mechanism. The operating handle is characterized by comprising a handle body and connector, wherein the handle body comprises a griping part and a connection part, the griping part is used for an operator to grip, bulges are arranged on the periphery of the connection part, the handle body is arranged at the connector, opening grooves are formed in the connector and are used for the bulges to rotate in a circumferential direction of the connector, the number of the bulges is the same as the number of the opening grooves, the connector is driven to rotate when the bulges are rotated at end parts of the opening grooves, and the span of the bulges in the circumferential direction of the connection part is smaller than the space of the opening grooves in the circumferential direction of the connection part by over 30 degrees. By the operating handle, a spring can be prevented from rapidly releasing energy to hurt the operator.

Description

technical field [0001] The invention relates to a spring operating mechanism, in particular to an operating handle for the spring over-centering operating mechanism and a spring over-centering operating mechanism with the operating handle. Background technique [0002] The spring over-center operating mechanism drives the main shaft to rotate through the operating shaft (or called the input shaft), and compresses or stretches the spring to store energy. When the mechanism moves to the dead point, and then rotates a small angle, the spring will release energy, driving the main shaft to rotate rapidly, thereby outputting energy. [0003] In the spring over-center operating mechanism in the prior art, the commonly used operating handle is that one end of the operating handle has a connector, which is directly or indirectly connected to the main shaft through the connector, although the spring over-center operating mechanism generally designs a relief slot at the main shaft blo...
