Specific embodiment
The screw wrench of present embodiment is as shown in Figure 1, including sleeve 1, tightening handle 2, ratchet handle 4, fixing end
Face 3 and lengthening handle 5.As depicted in figs. 1 and 2, sleeve 1 is cylindrical structure, the hexagon inserting hole of inside setting up and down
12, sleeve 1 can be provided with 6 by 12 sets of inserting hole on hex(agonal)screw, on the upper and lower end face of sleeve 1 and symmetrical above and below lack
Mouth 11.Sleeve 1 is made of international No. 45 steel, and the center of interior hexagon is overlapped with the center of sleeve cylindrical body, notch 11 and
The each edge of interior hexagonal is parallel.For various sizes of hex(agonal)screw, the size of sleeve 1 is not also identical, sleeve 1 it is preferred straight
Diameter is equal to nut size+8mm, and the height of sleeve 1 can be 40mm according to plain edition Uniform provisions, and 11 depth of notch of sleeve 1 is
4mm, length and width are all 5mm.In use, 1 set of sleeve on screw, since sleeve 1 is communicating structure, screw can be included in sleeve 1
In, operating space required for above nut has been further reduced, when using on long bolt, can cover on long bolt, make
User twists long bolt by rotational sleeve 1.
As shown in figures 1 and 3, tightening handle 2 can be fixed on sleeve 1, and the head for tightening handle 2 is arranged 2
Clamp 21, clamp 21 can be connected in the notch 11 of sleeve 1, turn sleeve 1 by tightening handle 2 in narrow space.It twists
The a length of 200mm of tight handle 2, one section of Double-end clamp 21 for width 30mm, the other end have the first connecting hole 22.
As shown in Figure 1, Figure 4 and Figure 5, screw wrench can also pass through ratchet handle 4 and fixed end face 3 in the proper space
It is operated.Fixed end face 3 is in two sides structure, and there are six the raised line 31 at 60 ° of angles, protrusion is in rectangular parallelepiped structure, convex for lower end
Item 31 is matched with notch 11, and width and height are all 5mm, and fixation hole 32 is arranged in the upper end of fixed end face 3.Ratchet handle by
Ratchet fixed link and ratchet are constituted, and ratchet is daily general ratchet, and the setting of 4 head of ratchet handle is matched with fixation hole 32
