In order to solve the above problems, the utility model provides a deformation wrench, concrete technical scheme is:

a deformation wrench comprises an upper wrench, a lower wrench and an extension handle, wherein a sliding groove is embedded in the upper surface of the lower wrench, an embedded block matched with the sliding groove is arranged on the lower surface of the upper wrench, so that the upper wrench and the lower wrench can be connected in an embedded mode, and the head end and the tail end of the upper wrench and the tail end of the lower wrench are fixedly connected through pins; the tail end extension of spanner forms the stiff end down, goes up the tail end of spanner and forms the fixed slot to the head end is sunken, the one end of extension handle set up with stiff end assorted link, the link is provided with the fixed block that can insert in the fixed slot, the stiff end is with link fixed connection with the pin, the inside of the extension handle other end inlays the bottle opener that is equipped with dismantled and assembled pin.

Furthermore, the extension handle can be provided with a plurality of sections, and a fixing groove and a fixing block which are matched are arranged between the two extension handles and are connected by adopting pins.

Further, the pin is connected with the fixed end or the lower wrench through a spiral caulking groove.

Further, a pin box is arranged on the extension handle.

Furthermore, the tail end of the screwdriver is provided with a fixing ring, and the end part of the screwdriver grip is provided with threads so that the screwdriver is in threaded connection with the inner part of the tail end of the extension handle.

Has the advantages that:

the utility model discloses a spanner can carry out quick assembly disassembly, and the spanner attenuation after disassembling, shorten can be applicable to turning, dead angle or finite space and carry out the operation, convenient to carry.

Detailed Description

The invention will be further described with reference to the following drawings and specific embodiments:

as shown in fig. 1-3, a deformation wrench comprises an upper wrench 1, a lower wrench 2 and an extension handle 3, wherein a sliding groove is embedded in the upper surface of the lower wrench 2, an embedded block matched with the sliding groove is arranged on the lower surface of the upper wrench 1, so that the upper wrench 1 and the lower wrench 2 can be connected in a jogged manner, and the head end and the tail end of the upper wrench 1 and the tail end of the lower wrench 2 are fixedly connected by a pin 7; the tail end of lower spanner 2 extension forms stiff end 4, goes up spanner 1's tail end and forms the fixed slot to the head end sunken, the one end of extension handle 3 sets up and 4 assorted links 5 with stiff end, link 5 is provided with the fixed block 6 that can insert in the fixed slot, stiff end 4 and link 5 are with pin 7 fixed connection, the bottle opener that is equipped with dismantled and assembled pin 7 is inlayed to the inside of the 3 other ends of extension handle.

As shown in fig. 3, the extension handle 3 may be provided with multiple sections, and a fixing groove and a fixing block 6 are provided between the two extension handles 3, and are provided at the similar fixing end 4 and the connecting end 5, and are connected by a pin 7.

In this embodiment, the number of the pins 7 used for connecting the fixed end 4 and the connecting end 5 is at least four; the pin 7 is connected with the fixed end 4 or the lower wrench 2 through a spiral caulking groove. Specifically, the inside spiral slot that sets up of pinhole of stiff end 4 or lower spanner 2 installation pin 7, the lower extreme setting of pin 7 with its assorted spiral abaculus, rotatory pin 7 can make the abaculus embedding slot on it in to locking each part, also can realizing fast assembly and dismantlement.

In this embodiment, the extension handle 3 is provided with a pin box 8 for collecting the detached pins 7; the pin box 8 is provided with a box cover connected through a buckle.

In the embodiment, the top end of the pin 7 is provided with a cross opening or a straight opening matched with the screwdriver; the tail end of the screwdriver is provided with a fixing ring, and the end part of the screwdriver grip is provided with threads so that the screwdriver is in threaded connection with the inner part of the tail end of the extension handle 3.

When in use, the deformation wrench is disassembled according to the condition of the operation space; holding the fixing ring of the screwdriver, and rotating the screwdriver so as to take the screwdriver out of the extension handle 3; when the spanner needs to be shortened, the pin 7 is disassembled by the screwdriver, so that the extension handles 3 with proper quantity are disassembled, and when the spanner needs to be thinned, the pin 7 on the extension handle 3 and the upper spanner 1 is disassembled, so that the operation is carried out by the upper spanner 1 or the lower spanner 2. When the bolt is thick or the operation space is large, the upper wrench 1 and the lower wrench 2 can be connected by the embedded block and the sliding groove, then the fixing block is inserted into the fixing groove, and the upper and

lower wrenches
