Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

It will be understood that when an element is referred to as being "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "upper," "lower," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Referring to fig. 1 to 5, a restricted area bolt dismounting device includes a driving pulley 2, a timing belt 3, and a first driven pulley 6; a through hole 61 is formed in the first driven wheel 6, the shape of the through hole is the same as that of the outer surface of the bolt to be disassembled, and the bolt to be disassembled can penetrate through the through hole 61;

the driving wheel 2 and the first driven wheel 6 are connected through the synchronous belt 3.

The working principle is as follows: firstly, adopt box spanner to treat the one end of dismantling the bolt and fix, another pot head is established in through-hole 61, then at convenient position installation action wheel 2, connect action wheel 2 and first follow driving wheel 6 with hold-in range 3, drive action wheel 2 through external force and rotate to drive first from driving wheel 6 and rotate, first follow driving wheel 6 rotates and drives and treat that the bolt that dismantles rotates, realizes the dismantlement of restricted zone bolt.
