AI Technical Summary

Problems solved by technology

When in use, the adjusting nut is constantly rotated, and the opening of the movable jaw relative to the fixed jaw is changed by adjusting the sliding of the movable jaw. Therefore, the operation is very inconvenient; at the same time, the opening and closing speed of the traditional pipe wrench jaw Also limited by the thread pitch, it is impossible to realize the quick opening and closing of the jaws

Embodiment Construction

[0059] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0060] figure 1 with figure 2 It is a schematic diagram of a wrench 100 in a preferred embodiment of the present invention, and its structure includes: a guide rod 2, a first claw 1 installed on the guide rod 2, a sliding part 31 threaded on the guide rod 2, and an installation On the sliding part 31 and the second claw 32 matched with the first claw 1, the wrench 100 also includes a tooth block 34 arranged inside the sliding part 31 and cooperating with the guide rod 2. The tooth block 34 has a first position and a second position. Location.

[0061] The wrench 100 is configured such that: when the tooth block 34 is in the first position, the tooth block 34 engages with the guide rod 2, the tooth block 34 can slide along the guide rod 2 toward the first claw 1, and moves away from the first claw 1 The direction is locked; when the tooth block 34 is...

Abstract

The invention discloses a spanner. The spanner structurally comprises a guide rod, a first clamping jaw, a sliding part, a second clamping jaw and a gear block. The first clamping jaw is installed on the guide rod, the sliding part penetrates the guide rod in a sleeving manner, the second clamping jaw is installed on the sliding part and matched with the first clamping jaw, the gear block is arranged on the sliding part and matched with the guide rod, and the gear block has a first position and a second position. When the gear block is located at the first position, the gear block can slide towards the first clamping jaw along the guide rod and is locked in the direction deviating from the first clamping jaw. When the gear block is located at the second position, the gear block can slide in the direction facing the first clamping jaw or deviating from the first clamping jaw along the guide rod.

Description

technical field [0001] The invention relates to a hand tool, in particular to a wrench, which can be used to clamp flat plates, nuts, especially pipe fittings such as steel pipes and plastic pipes. Background technique [0002] In daily life or work, it is often necessary to use a wrench to clamp objects, such as clamping steel pipes, plastic pipes and other pipe fittings to realize the elastic installation or removal of pipe fittings. Traditional wrenches for clamping pipe fittings, such as pipe wrench, are generally composed of fixed jaws, movable jaws, pliers handles, adjusting nuts and other components. The fixed jaws and pliers handles are fixed together, and the structure is complex. The traditional pipe wrench relies on the transmission of the thread pair between the nut and the movable jaw to realize the opening and closing of the jaw. When in use, the adjusting nut is constantly rotated, and the opening of the movable jaw relative to the fixed jaw is changed by adj...
