Description

Adjustable socket wrench

Technical Field

The utility model relates to the technical field of bolt construction tools, in particular to an adjustable socket wrench.

Background

Wrenches are one of the repair tools commonly used in our lives, and are hand tools that use the lever principle to turn bolts, nuts and other threads to tighten the openings or trepanning fasteners of the bolts or nuts. The wrench is generally provided with a chuck at one or both ends of a shank, which clamps an opening or a socket of a bolt or a nut, and the shank is rotated in a screw rotation direction by applying an external force to the shank, thereby turning the bolt or the nut. Wrenches are typically made of carbon structural steel or alloy structural steel.

The form and variety of wrenches may vary due to the different sizes and specifications of the bolts and nuts and the different applications. Common wrenches include box wrenches, socket wrenches, and hex wrenches. For the socket spanner, the size and the shape of the clamping head are fixed, and the socket spanner can only be used for assembling and disassembling bolts or nuts with one size specification, so that the spanner which needs to be prepared in construction has a large number of sizes and is inconvenient to use.

Example 1

As shown in fig. 1-3, an adjustable socket wrench comprises a fixed disc main body 1, wherein a four-corner connector 5 is arranged at the top end of the fixed disc main body 1, a handle 6 is detachably connected with the fixed disc main body 1 through the four-corner connector 5, the handle 6 can be effectively fixed by adopting the four-corner connector 5, rotation between the handle 6 and the fixed disc main body 1 is avoided, and stable and convenient holding of staff is ensured. The handle 6 can be driven manually or electrically, and a driving motor is arranged at one end of the handle 6 far away from the fixed disc main body 1 during electric driving. The handle 6 can be detached and is convenient to store, and different handles 6 can be replaced according to the needs.

The bottom end of the fixed disc main body 1 is provided with a plurality of clamping claws 4, and the inner wall of the clamping claws 4 is provided with an end face clamped with the shape of the end part of the bolt or threads corresponding to the bolt so as to clamp the bolt. The bottom of the fixed disc main body 1 is provided with sliding grooves 7 along the radial direction, and the sliding grooves 7 are in one-to-one correspondence with the clamping claws 4, so that the clamping claws 4 can be limited to move along the radial direction of the fixed disc main body 1. Preferably, three clamping claws 4 are arranged, the clamping claws 4 are uniformly distributed at the bottom of the fixed disc main body 1, and the clamping claws uniformly apply force when clamping bolts. The claw 4 moves radially along the fixed disc main body 1, the distance between the different claws 4 can be changed, bolts of various sizes and models are further used, a wrench is not required to be replaced frequently, the operation is simple and convenient, and the working strength of workers is reduced.

The fixed disk main body 1 outside cover is equipped with the rolling disk 3, and the rolling disk 3 outside is equipped with anti-skidding line, the staff of being convenient for operates the rolling disk 3. The bottom of the rotating disc 3 is in threaded connection with the top of the claw 4. The bottom of the rotating disc 3 is connected with the fixed disc main body 1 in a sliding way. The locking direction of the screw thread at the top end of the claw 4 is opposite to the locking direction of the clamping bolt inside the claw 4, so that the claw 4 is ensured to be locked inwards when the bolt is rotated, and the stable clamping of the bolt is realized. The junction of rolling disc 3 top and fixed disk main part 1 is equipped with jump ring 2, can provide the resistance to the rotation of rolling disc 3, avoids rolling disc 3 excessive rotation to open jack catch 4 and makes the bolt slippage.
