Detailed Description

As shown in fig. 1-3, a multipurpose wrench suitable for narrow space, includes handles 1, handles 1 be two, two handles 1 one end is equipped with arc tail section 5, and the other end is equipped with semi-circular head, and two handles 1 are articulated through screw knob 4 and are formed scissors structure on being close to semi-circular head's position, and two semi-circular head are constituteed and are formed circular shape box spanner head 2, and two arc tail sections 5 on two handles 1 other ends make up and form "U" shape structure, are equipped with sleeve spanner head 6 in the "U" shape structure.

In the preferred scheme, the two handles 1 are provided with cutting edges on the inner side of one end close to the plum blossom wrench head 2, and the two cutting edges form a cutting tool 3.

In a preferable scheme, one of the handles 1 is provided with an arc-shaped rod 7, the other handle 1 is provided with a fixing block 9, the fixing block 9 is provided with a through hole 14, one end of the arc-shaped rod 7 is fixed on the handle 1, and the other end of the arc-shaped rod passes through the through hole 14 on the fixing block 9.

In the preferred scheme, the concave arc surface of the arc rod 7 faces the direction of the plum blossom wrench head 2, the convex arc surface of the arc rod 7 is provided with a positioning ratchet 8, a wedge-shaped positioning block 15 is arranged in the fixing block 9, and the wedge-shaped positioning block 15 and the positioning ratchet 8 are mutually matched to realize the clamping action between the two handles 1.

In a preferable scheme, one side of the wedge-shaped positioning block 15 abuts against the convex arc surface of the arc-shaped rod 7, the other side of the wedge-shaped positioning block is provided with a pull rod 17, the pull rod 17 penetrates through a pull rod hole 16 formed in the side wall of one side of the through hole 14 and extends out of the fixing block 9, and a spring 18 is sleeved on the portion, located in the through hole 14, of the pull rod 17.

In a preferred scheme, the circle center of the circle where the arc-shaped rod 7 is located on the screw knob 4.

In an optimized scheme, the socket wrench head 6 comprises an inserting plate 10 and a socket body 12, one end of the socket body 12 is fixed on the inserting plate 10, the other end of the socket body 12 is provided with a socket opening 13, the inner sides of the two arc-shaped tail sections 5 are provided with inserting grooves 11, and the inserting plate 10 is inserted into the inserting grooves 11 to realize the connection and fixation between the socket wrench head 6 and the handle 1.

The application method and the principle are as follows:

when the screwdriver is used, the handle 1 is pulled open by two hands, the plum blossom wrench head 2 at one end of the handle 1 is opened, the screw is sleeved to be fully meshed with the screw surface, then the handle 1 is closed, the plum blossom wrench head 2 is clamped, and the handle 1 is held by hand to perform screw tightening operation;

or the handle 1 is directly gripped to close the plum blossom wrench head 2, the plum blossom wrench head 2 is sleeved in the screw, and the handle 1 is gripped to perform the tightening and loosening operation.

At the in-process of clenching handle 1, clenching handle 1 as far as possible according to the screw size and continuing to press close to, cooperation arc pole 7 restricts handle 1 with fixed block 9 to promote the ability that the spanner bears moment.

When the cutting tool 3 is used, the handle 1 is opened, the pull rod 17 is pulled, the wedge-shaped positioning block 15 does not limit the positioning ratchet 8 any more, then the handle 1 is opened until the arc-shaped rod 7 is separated from the fixing block 9, and at the moment, the arc-shaped rod 7 is rotated, so that the arc-shaped rod cannot penetrate through the fixing block 9 in the subsequent movement process of the handle 1; then will wait to cut the mark and place in the region of cutting tool 3, close handle 1 and can realize the shearing operation, it needs to be noted that, cutting tool 3 part is not suitable for the too high object of shear strength, otherwise screw knob 4 can damage, influences this product life.

When the sleeve wrench head 6 at the tail part is used, the handle 1 is closed firstly, and then the sleeve wrench head 6 (sleeve interface) is placed in a U-shaped area formed by the arc-shaped tail section 5 (the insertion plate 10 is inserted into the slot 11 to realize fixation). When using socket spanner head 5, arc pole 7 and fixed block 9 cooperate once more, realize the clamp between the handle 1 tightly, avoid handle 1 to open and lead to socket spanner head 6 to drop.
