Abstract

The invention discloses a multifunctional spanner and relates to the technical field of hand tools. The multifunctional spanner comprises a shell, a movable clamping block, a manual button and limiting pillars. The movable clamping block is movably arranged on the upper portion of the shell. The limiting pillars are annularly arranged at the top of the shell and used for being matched with the movable clamping block to clamp a nut. The manual button is arranged in the middle of the shell. The movable clamping block can be controlled to swing by pulling the manual button, and accordingly the movable clamping block and the nut can be clamped. A stepping motor is arranged inside the shell and can be used for controlling the movable clamping block to swing, and the movable clamping block and the nut are clamped. The multifunctional spanner can lock the nut conveniently, effectively and rapidly.

Description

technical field [0001] The invention relates to the technical field of hand tools, in particular to a multifunctional wrench. Background technique [0002] In the field of hand tools, a wrench is one of the most common tools, and has a wide variety of functions. In industrial production, a wrench for tightening bolts is often used. After the bolt is inserted, the knob-type adjustment is performed to match the size of the nut, and then tightened, resulting in low tightening efficiency and poor tightening effect. [0003] For example, the Chinese invention CN107695936A discloses an intelligent wrench, which includes: one end of the wrench body is provided with a set of bolt claws, and the surfaces of the opposite sides of the set of bolt claws are provided with intelligent telescopic buckle mechanisms. The buckle mechanism consists of an arc-shaped slot opened inward on the surface of one side of the bolt claw, a telescopic motor embedded in the bottom surface of the arc-shap...
