[0020] The technical scheme of the utility model will be described clearly and completely below in conjunction with the embodiments, and obviously, the described embodiments are a part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the protection scope of the utility model.
[0021] In the description of the utility model, it is understood that the orientation or position relation indicated by the terms such as 'up', 'down', 'left', 'right' is the orientation or position relation based on the drawing shown, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element indicated must have a particular orientation, be constructed and operated in a particular orientation, so it cannot be understood as a limitation on the utility model.
[0022] In the description of the utility model, still need to explain, unless another explicit provision and limitation, term '' set '', '' install '', '' link '', '' connect '' should do broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be directly connected, also can be indirectly connected through the intermediate medium, can be two element internal communication. For ordinary skilled in the art, the above-mentioned terms can be understood in the utility model with the specific meaning of the specific situation.
[0023] In order to avoid too many unnecessary details, the structure or function belonging to the following examples will not be described in detail.
[0024] As Figures 1-4 As shown in the structure diagram of the operating handle of the explosion-proof distribution box, which is a preferred embodiment of the utility model;
[0025] In this embodiment, the base 1 is provided with a handle seat 2 on the top, the handle seat 2 is provided with a handle part 3 on the top surface, the handle part 3 is provided with an inner cavity 4 on one end, the first extension handle 5 is slidably arranged in the inner cavity 4, the first extension handle 5 is provided with an inner groove 6 on the top surface, the second extension handle 7 is rotatably arranged in the inner groove 6, the handle part 3 and the first extension handle 5 are both provided with a through hole 8, and the pin 9 is inserted into the through hole 8. When the first extension handle 5 is received in the inner cavity 4, the first extension handle 5 is fixed and limited by the pin 9. When in use, the pin 9 is pulled out of the through hole 8, the first extension handle 5 is pulled out of the inner cavity 4, and the second extension handle 5 is turned out of the inner groove 6, so that the size of the handle part 3 can be lengthened, the force arm is lengthened, the hand gripping area of the operator is larger, the phenomenon of hand slipping when the operator twists the handle part 3 is avoided, and the operator twists the operating handle more conveniently and labor-savingly.
