Definitions

  • the present invention relates to an adjustable socket structure that is capable of simplifying related components and assembling process.
  • a conventional adjustable socket structure disclosed in US Pat. No. 6,622,598 contains a sleeve head, a sleeve body, and a set of pawls.
  • the sleeve head is coupled on the bottom with the sleeve body, and both of them can rotate freely.
  • the sleeve body has multiple slide rails distributed on its inner wall evenly the pawls slide in these slide rails, and the shafts on the top of these pawls extrude to the space designed between the sleeve head and the sleeve body.
  • Connected to the shafts are corresponding connecting rods, which have corresponding pins fixed onto the sleeve head.
  • the sleeve head When the sleeve head rotates, it drives the pawls through the connecting rods to open/close simultaneously. In this way, when the operator turns the sleeve barrel clockwise/anti-clockwise, the pawls will screw a nut down/up together, which is convenient and practical.
  • the conventional socket structure is complicated without being assembled easily.
  • the present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
  • the primary object of the present invention is to provide an adjustable socket structure that is capable of simplifying related components and assembling process.
  • Further object of the present invention is to provide an adjustable socket structure in which the disk portion is prevented from crashing other components to achieve a noise proof purpose.
  • Another Further object of the present invention is to provide an adjustable socket structure that is capable of obtaining a strong structure
  • An adjustable socket structure provided by the present invention contains:
  • an adjustable socket structure comprises a body 10, three paws 20, three connecting rods 30, a driving shaft 40, and a retaining ring 50.
  • the body 10 is formed in a cylinder shape and includes a first groove 11 disposed on a rear surface thereof, a second groove 12 with a smaller diameter fixed on a bottom end of the first groove 11, and a first notch 13 formed on the first groove 11.
  • the body 10 includes three slots 14 radially arranged on a front end of the body 10 and communicating with the second groove 12, each slot 14 includes two recesses 15 secured on two walls thereof respectively and two ribs 16 fixed on two front ends of the recesses 15 individually.
  • Each paw 20 includes a sliding block 21 to be movably retained in the slot 14, and the sliding block 21 includes two second notches 22 secured on two sides thereof respectively to retain the two ribs 16, a first hole 23 formed on a rear side thereof, a V-shaped locking face 24 to retain with a screwing element 60, and the screwing element 60 is a nut or a screw bolt; the paw 20 also includes an arcuate cutout 25 formed on a bottom end of the locking face 24, and a plurality of teeth 26 arranged on the locking face 24 to engage with various screwing elements 60 as illustrated in Fig. 9 .
  • Each connecting rod 30 is movably fixed in the second groove 12 and includes a first axial shank 31 disposed on one side thereof to be rotably inserted in the first hole 23 and a second axial shank 32 fixed on another side thereof.
  • the driving shaft 40 includes an axial portion 41 and a disk portion 42 located at a front end of the axial portion 41, wherein the axial portion 41 is formed in a polygonal column shape (such as a hexagon column) to fit with a wrench and includes a square bore 43 to retain a wrench or a coupling extension.
  • the disk portion 42 is circular to be rotated in the first groove 11 and includes an outer diameter which is larger that the axial portion 41, three second hole 44 used to insert the second axial shanks 32 of the three connecting rods 30 so that the driving shaft 40 is rotated to actuate the three paws 20 to move in the slots 14 respectively by using the three connecting rods 30, thus engaging or disengaging the screwing element 60 as shown in Figs. 7 and 9 .
  • the retaining ring 50 is helical and retained in the first notch 13 to abut against a rear end of the disk portion 42 of the driving shaft 40 so that the disk portion 42 is limited in the first groove 11.
  • the driving shaft 40 is rotated in a clockwise direction, and the second axial shanks 32 are actuated by the disk portion 42 of the driving shaft 40 in the clockwise direction so that the connecting rods 30 actuate the paws 20 to move in the slots 14, hence the retaining faces 24 engage with the screwing element 60.
  • the wrench is rotated in the clockwise direction as well to actuate the driving shaft 40, and then the paws 20 retain the screwing element 60 and actuate the screwing element 60 to rotate in the clockwise direction.
  • the second axial shanks 32 move back to the central positions of three slots 14 so that the connecting rods 30 actuate the paws 20 to expand, thus releasing the screwing element 60.
  • the driving shaft 40 is rotated to further turn the axial shanks 32 in the anti-clockwise direction so that the connecting rods 30 actuate the paws 20 to move in the slots 14, hence the locking faces 24 retain the screwing element 60.
  • the wrench is capable of rotating the driving shaft 40 in the anti-clockwise direction, and the paws 20 retain the screwing element 60 and actuate the screwing element 60 to rotate in the anti-clockwise direction.
  • first axial shank 31 and the second axial shank 32 are connected with the paws 20 and the driving shaft 40 to simplify related components and assembling process.
  • the retaining ring 50 is biased against the disk portion 42 of the driving shaft 40 so that the disk portion 42 axially rotates in the first groove 42 without axially moving so that the disk portion 42 is prevented from crashing other components to achieve a noise proof purpose.
  • Numbers of the paws 20 and the connecting rods 30 are not limited to three, i.e., at least two paws 20 and connecting rods 30 are allowable.
