Detailed ways

The utility model will be described in further detail below in conjunction with the accompanying drawings and specific embodiments: as shown in Figure 1, Figure 2, Figure 3 and Figure 4, a socket wrench for elongated bolt fastening, the wrench includes a top tightening The fixed end, the operating end of the bottom and the connecting rod 1 for connecting the fastening end and the operating end, the fastening end includes a base 2, and the first inner hexagonal sleeve 3 is fixed on the base 2, and the first inner hexagonal sleeve 3 is fixed on the base 2 The top of the inner hexagonal sleeve 3 is provided with a second inner hexagonal sleeve 4, and the bottom of the second inner hexagonal sleeve 4 is rotatably connected with the upper surface edge of the first inner hexagonal sleeve 3 through the first rotating shaft 6. In the second The top of the inner hexagonal sleeve 4 is provided with a third inner hexagonal sleeve 5, and the bottom of the third inner hexagonal sleeve 5 is rotatably connected with the upper surface edge of the second inner hexagonal sleeve 4 through the second rotating shaft 7. The radius of the circumscribed circle corresponding to the regular hexagon inside the second inner hexagonal sleeve 4 is greater than the radius of the circumscribed circle corresponding to the regular hexagon inside the first inner hexagonal sleeve 3 , and the inside of the third inner hexagonal sleeve 5 The radius of the circumscribed circle corresponding to the regular hexagon is greater than the radius of the circumscribed circle corresponding to the regular hexagon inside the second inner hexagonal sleeve 4, the second inner hexagonal sleeve 4 and the third inner hexagonal sleeve 5 by means of Fix it to the base 2 with the bolt 8.

Threaded holes 9 in the vertical direction are provided on the cylinder walls of the second inner hexagonal sleeve 4 and the third inner hexagonal sleeve 5, and a threaded hole 9 that is aligned up and down with the threaded hole 9 and has the same diameter is provided on the base 2. Threaded groove, the second hexagonal socket 4 and the third hexagonal socket 5 are connected by means of bolts 8 inserted into the threaded hole 9 and the threaded groove at the same time, and the bottom surface of the third hexagonal socket 5 is also provided with a Hex socket 10 for the nut of the bolt 8 .

The operating end is two reinforcing rods 11, one end of which is rotatably connected to the rod body of the connecting rod 1. The two reinforcing rods 11 are on the same vertical plane, and there is also a limiting force on the rod body of the connecting rod 1 at the operating end. The limit block 12 that the rod 11 rotates.

The fastening end and the operating end of the box wrench are connected by a connecting rod 1, and the fastening end has a base 2. The upper surface of the base 2 is provided with three inner hexagonal sockets, and the inner hexagonal sockets inside the three inner hexagonal sockets The three inner hexagonal sockets are arranged in the vertical direction, and the inner diameter of the first inner hexagonal socket 3 at the bottom is the smallest, which is suitable for screwing smaller screws.
