Furthermore, the starting end of the pressure lever is provided with a connecting hole for connecting a hook, and the tail end of the pressure lever is provided with a sleeve for pressing down. The connecting hole and the hinge hole are both round holes,
further, the distance between the hinge hole and the connecting hole is smaller than the distance between the hinge hole and the sleeve. So as to save physical strength by utilizing the lever principle.
Further, the support includes the base and is fixed in the ear of base both sides, the region in the middle of the ear of base and base both sides is used for holding the depression bar. The base needs to be placed or fixed on a GW5 type knife switch when in use.
Furthermore, the ear all is equipped with the through-hole, works as the through-hole when the axis of hinge hole is coincide, the articulated elements can pass the through-hole with the hinge hole. In this embodiment, the hinge is a bolt, and when the bolt is used as the hinge, the bolt is further fixed from the other end portion of the bolt by using a nut.
Further, the base is cylindrical.
Further, the ear includes vertical portion and flexion, vertical portion all is perpendicular to the base, the flexion to the axis direction of base is crooked, the through-hole sets up at the flexion end. Such an arrangement is used to facilitate the use of a bench-top tool to manufacture the ear.
The utility model discloses utilize lever principle to solve not having GW5 type switch contact spring change instrument on the market, the difficult problem that the difficulty was wasted time and energy is changed to the manpower. Because the knife switch contact is smaller, the supporting part is not easy to manufacture, and the bottom of the supporting part is made into a cylinder shape, so that the supporting effect is firmer on one hand, and the knife switch contact is easier to process on the other hand.
Compared with the prior art, the utility model, have following advantage:
1. the utility model discloses a scheme, the result of application is showing in the disconnecting link maintenance work, simple manufacture, convenient operation, saving manpower.
2. The utility model discloses an among the scheme, make full use of lever principle to use the couple as final executive, be favorable to overhauing and changing the spring of GW5 type switch.
