Abstract

The invention relates to a ratchet wrench. The ratchet wrench comprises a handle and a wrench head arranged at the front end of the handle, and further comprises a first connecting rod and a second connecting rod, wherein the rear end of the first connecting rod is connected to the front end of the handle; the front end of the first connecting rod is inwards sunken to form a first connecting head; the rear end of the wrench head is provided with a second connecting head adaptive to the first connecting head; the rear end of the second connecting rod is provided with a third connecting head adaptive to the first connecting head; and the front end of the second connecting rod is inwards sunken to form a fourth connecting head adaptive to the second connecting head. According to the ratchet wrench, the second connecting rod is connected between the wrench head and the handle in a splicing manner, so that the integral length of the ratchet wrench can be prolonged; the wrench head is directly connected to the front end of the handle, and can be used as a common ratchet while the weight of the ratchet wrench is not increased, so that the use is convenient; and meanwhile, the detachable type connecting structure among the parts on the ratchet wrench is also very convenient for assembling and carrying.

Description

technical field [0001] The invention relates to the technical field of ratchet wrench, in particular to a ratchet wrench capable of extending the length. Background technique [0002] At present, the handles of common ratchet wrenches on the market are generally fixed in length, and the length of the ratchet wrench cannot be adjusted according to needs. When a larger torque is required, a ratchet wrench with a longer handle needs to be selected. Such a ratchet wrench is extremely inconvenient to carry. . In order to solve the above problems, the Chinese utility model patent "A Telescopic Ratchet Wrench" (application number: 200620021666.6) with the authorized announcement number CN200970742Y discloses a structure, which includes a wrench head, a fixed handle and a movable handle, the wrench head and the fixed handle. The handles are connected, and there is a chute in the fixed handle. The movable handle that can slide in the fixed handle chute is connected with the fixed ha...
