Detailed Description

the following describes embodiments of the present invention with reference to the drawings.

Fig. 1 and 2 show a longitudinal sectional view and a top view of a sub-component 1 of the combination wrench of the present embodiment, the sub-component 1 is an elongated sub-component, and two ends of the elongated sub-component are respectively provided with a first through hole 2 and a second through hole 3, wherein the first through hole 2 is an 1/2 square inch interface, the second through hole 3 is a hexagonal through hole, a fixing hole 5 is further provided on the edge of the second through hole 3, the fixing hole 5 penetrates through the side wall of the second through hole 3 and is arranged perpendicular to the axis of the second through hole 3, the fixing hole 5 in the present embodiment is located at the top end of the sub-component 1, and can be located at any position on the side wall of the second through hole 3. When the hexagon socket head cap member is inserted into the second through hole 3, the hexagon head cap member can be fixed by screwing the fixing bolt into the fixing hole 5.

In an embodiment of the present invention, the combination wrench includes two sub-components 1, as shown in fig. 3, two ends of an inner hexagonal rod 4 are respectively and fixedly inserted into the second through holes 3 of the two sub-components 1, so as to connect the two sub-components 1 into a wrench body with a zigzag structure, according to the target of the required operation, such as a bolt, a nut, etc., a corresponding operation portion, such as an inner hexagonal, an outer hexagonal, etc., is inserted into the first through hole 2 of one of the sub-components 1, so that the operation can be performed in different planes of the operation target by using the zigzag wrench.

Several different forms of the combined wrench of this embodiment are shown in fig. 4 to 6, two sub-components 1 are connected by an inner hexagonal rod 4, and they can form a certain included angle, because the second through hole 3 is a hexagonal through hole, the included angle between the two sub-components 1 can be selected from several different ones, and according to the actual situation of the application scenario required, the operator can adjust the combined wrench of this embodiment to different included angles. The sub-elements 1 shown in FIG. 4 are at an angle of 90 degrees, the sub-elements 1 shown in FIG. 5 are at an angle of 120 degrees, and the sub-elements 1 shown in FIG. 6 are at an angle of 150 degrees.

In addition to the above-mentioned connection, in another embodiment of the present invention, the two sub-members 1 are fixedly connected by the first through-holes 2, and a square pin can be provided and fixed in the two first through-holes 2. Since the first through hole 2 is an 1/2 square inch interface, the selectable angle is small compared with the connection mode of the second through hole 3, but when the hexagon socket head cap screw needs to be operated, the two sub-components 1 are connected through the first through hole 2, and then the hexagon socket head cap rod 4 arranged in the second through hole 3 can be directly used as an operation component.

In another embodiment of this embodiment, the first through hole 2 of one sub-component 1 and the second through hole 3 of the other sub-component 1 are fixed, a quincunx sleeve is additionally connected in the first through hole 2, one end of the quincunx sleeve is of a square structure and is matched with the 1/2 square inch connector of the first through hole 2, and the other end of the quincunx sleeve is of an outer hexagonal structure and is matched with the inner hexagonal rod 4 fixed in the second through hole 3 of the other sub-component 1. The cooperation of square inch interface and hexagon through-hole provides more possibilities for the angle of adjustment that can make up and obtain, and simultaneously, the cup joint of plum blossom sleeve and interior hexagonal pole 4 is more convenient nimble with dismantling than being connected through fixing bolt.
