Detailed Description

The following detailed description of embodiments of the invention refers to the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present invention, are given by way of illustration and explanation only, not limitation.

In the present invention, unless otherwise specified, the directional words "upper, lower, inner, outer" and the like included in the terms merely represent the orientation of the terms in a conventional use state or are colloquially understood by those skilled in the art, and should not be construed as limiting the terms.

As shown in fig. 1 to 4, the present invention provides a large nut rapid-rotating apparatus, which includes: the flexible toothed belt 4, the driving gear 3, the driving motor 7, the fixed seat 6 and the handheld part 5; an opening 8 is formed in the front side of the fixed seat 6, the driving gear 3 is vertically arranged in the opening 8 and is connected with a driving motor 7 in the fixed seat 6, and the driving motor 7 can drive the driving gear 3 to rotate along the direction of a central shaft of the driving gear 3; the flexible toothed belt 4 penetrates through the opening 8 and is sleeved on the driving gear 3, and sawteeth capable of being meshed with the driving gear 3 are arranged on the inner side of the flexible toothed belt 4; the rear side of the fixed seat 6 is provided with the handheld part 5.

In a preferred embodiment of the present invention, a battery 2 is further disposed on the fixed base 6, and the battery 2 is electrically connected to the driving motor 7 and the control switch 1 on the handheld portion 5.

In the above scheme, a worker can hold the hand-held part 5 by hand, and the control switch 1 on the hand-held part 5 can conveniently control the on and off of the driving motor 7, so as to control the screwing operation of the large nut.

In a preferred embodiment of the present invention, the upper surface portion of the holder 6 is recessed inward to form a receiving groove 10, and the battery 2 is disposed in the receiving groove 10. The side surface of the accommodating groove 10 is provided with a guide groove 11, the outer side surface of the storage battery 2 is provided with a guide block matched with the guide groove 11, and the guide block can slide along the guide groove 11.

In the above scheme, the dismouting of not only can being convenient for of above-mentioned structure battery 2 can guarantee moreover battery 2 is in the stability of working process, prevents that battery 2 from vibrations striking the inner wall of holding tank 10 causes battery 2's damage and safety problem.
