The accompanying drawings, which are incorporated in and constitute a part of this application, illustrate preferred embodiments of the utility model and together with the description, serve to explain the principles of the utility model and not to limit the scope of the utility model.

Referring to fig. 1, the present invention provides a replacing device for a high-voltage switch snap spring, in this embodiment, the replacing device includes a clamp body 1 and two handles 2, a tail portion of the clamp body 1 is detachably connected to the two handles 2, a worker can open or close the clamp body 1 by operating the handles 2, and further can install or detach the snap spring, wherein the handle 2 includes a sleeve 21 and a screw rod 22, the sleeve 21 is sleeved outside the screw rod 22 and is in threaded connection with the screw rod 22, and when the screw rod 22 rotates relative to the sleeve 21, the screw rod 22 can extend out of or retract into the sleeve 21, so as to extend or shorten the handle 2.

In actual use, the jump ring that is located the more shallow position can be changed earlier through the device to the staff, will 2 extension backs of handle are changed the jump ring that is located the more deep position again, and this device both can make the staff change the jump ring of the more deep position in the high-voltage switch, makes things convenient for the staff to change the jump ring that is located the less shallow position again.

Referring to fig. 1, as a preferred embodiment, the handle 2 further includes an anti-slip handle sleeve 23, and the anti-slip handle sleeve 23 is sleeved outside the screw rod 22 and is fixedly connected to the screw rod 22. The anti-skid handle sleeve 23 is convenient for a worker to hold and can play an anti-skid role when the worker uses the replacing device of the high-voltage switch clamp spring. Specifically, the anti-slip handle sleeve 23 may be made of rubber or plastic.

With reference to fig. 1, as a preferred embodiment, a limiting block 211 is formed on the inner side of the sleeve 21, and the limiting block 211 is used for limiting the opening angle of the clamp body 1, so as to prevent a clamping spring clamped by a worker from being damaged due to excessive force when the worker uses the replacing device.

Referring to fig. 2, fig. 2 is a schematic structural diagram of a preferred embodiment of a clamp body in a device for replacing a high-voltage switch clamp spring according to the present invention, in this embodiment, the clamp body 1 includes two clamp bodies 11, an elastic member 12 and a rotating shaft 13, a clamping portion 111 is formed at one end of each clamp body 11, the middle portions of the two clamp bodies 11 are rotatably connected through the rotating shaft 13, inner sides of the other ends of the two clamp bodies 11 are respectively fixedly connected to two ends of the elastic member 12, and the other ends of the two clamp bodies 11 are respectively detachably connected to a sleeve 21.
