Definitions

  • Such a socket wrench insert is known from German utility model 296 12 327. Since the part 24 (see FIGS. 5 and 6) is deformable during assembly, the holding arm 241 at the actuating end 22 can be pressed into the socket wrench insert 20 along the longitudinal groove 221. After insertion, the end portion 244 of the elastic member 24 is firmly pressed into the annular groove 222 at the operating end 22. Since the head portion 243 has a semicircular shape, the part 24 of the central bore 23 can dodge and be inserted along its outer peripheral wall surface. By means of the projecting section 242 on the holding arm 241, a screw nut 25 is tightened after being inserted into the actuating end 22 of the socket wrench insert 20 with the aid of tension, so that it cannot come loose.
  • the products of the above-mentioned utility model have achieved the intended aim and effect with regard to the manufacture and use.
  • the products have the following disadvantages: If the holding arm 241 is inserted into the longitudinal groove 221, the assembly when pushing the elastic part 24 into the socket wrench insert 20 is not so easy because of the bent end section 244 at the end of the part 24 and can thereby Manufacturing efficiency can not be increased because the end portion 244, which is fixedly pressed into the annular groove 222 of the socket wrench insert 20 to prevent falling out of the socket wrench insert 20, at both end portions 244 of the part 24 before assembling the elastic part with the socket wrench insert must be bent in the aforementioned utility model.
  • the present invention is therefore based on the object of providing a socket wrench insert which is easier to manufacture and assemble.
  • this object is achieved in that the annular groove is formed in the bottom region of the actuating end and the arcuate head section is pressed into the annular groove in a stationary manner and is guided along the outer circumferential surface of the central bore.
  • a socket wrench insert with 20 a connecting end with 21, an actuating end with 22, a central bore with 23, a longitudinal groove with 221, an annular groove with 222, an elastic part with 24, a holding arm with 241, a projecting section 242, a curved head portion 243, an end portion 244 and a nut 25.
  • a longitudinal groove 221 is provided on both opposite sides of the inner wall and an annular groove 222 in the bottom region of the actuating end 22. Since an elastic part 24 on the holding arm 241 has a projecting section 242 and a semicircular design in the head section 243 and is therefore deformable during assembly, the holding arm 241 can be pressed into the socket wrench insert 20 along the longitudinal groove 221 at the actuating end 22. Instead of the end section in the clamping manner known from the utility model described in the introduction, the elastic part 24 cooperates with its head section 243 with the socket wrench insert 20 in order to realize the clamping function.
  • both the formation of the end section on the elastic part 24 can be saved and the holding arm 241 of the elastic part 24 can be pressed very easily into the longitudinal groove 222 of the socket wrench insert, as a result of which the assembly is considerable is facilitated because the holding arm has no end portion.
  • a nut 25 is clamped to the operating end 22 of the socket wrench insert 20, and the protruding portion 242 on the support arm 241 is pressed by the elastic member 24 with tension against the nut 25 so that the nut 25 cannot easily fall out of the socket wrench insert.
  • the head portion 243 of the elastic member 24 has a semicircular configuration that is clamped in the inner annular groove 222.
