Description

Technical Field

[0001] The utility model relates to the technical field of socket wrenches, in particular to a telescopic socket wrench. Background Art

[0002] A socket wrench is a commonly used tool that has a socket head that fits over a nut. The handle is turned to rotate the socket head, which in turn allows the nut to be tightened or loosened on a bolt.

[0003] However, during use, the existing wrenches are generally suitable for tightening bolts or nuts in very narrow positions or deep recesses, thereby completing the disassembly and assembly of the bolts or nuts. However, in actual use, since the wrench cannot be retracted at the back, it is inconvenient for the staff to carry the wrench due to its length. At the same time, when the depth of the disassembly recessed position is greater than the length of the socket wrench, the wrench cannot be used, which brings trouble to the staff. Therefore, we propose a retractable socket wrench to solve the above problems. Utility Model Content

[0026] Through the above technical solution, the sliding groove 8 can make the slide plate 5 slide in its inner cavity, and the socket wrench body 7 can be effectively extended and retracted, that is, the socket wrench body 7 can be shrunk and carried, and the use length of the socket wrench body 7 can also be adjusted, thereby improving the use efficiency of the socket wrench body 7, not only solving the trouble of the staff, but also meeting the needs of the staff. Through the spring 11, the elasticity can be effectively utilized to drive the push plate 12 to move, so that the push plate 12 pushes the insertion rod 13 to move. The movement of the insertion rod 13 facilitates the insertion of the socket wrench body 7, avoiding the loosening of the socket wrench body 7 during contraction or use, thereby improving the stability of the use of the socket wrench body 7.

[0027] Specifically, a socket hole 6 is provided on the surface of the socket wrench body 7, and the right side of the insertion rod 13 is inserted into the inner cavity of the socket hole 6. The left side of the shrinkage shell 1 is fixedly connected to the connecting column 3, and the left side of the connecting column 3 is fixedly connected to the handle 2. The surface of the handle 2 is provided with a rubber sleeve 4, and the surface of the rubber sleeve 4 is provided with anti-slip grooves. Both ends of the inner cavity of the limit shell 9 are provided with a slide groove, and both ends of the push plate 12 are slidably connected to the inner cavity of the slide groove. Through the socket hole 6, the socket wrench body 7 can be effectively connected with the insertion rod 13 at different lengths, thereby improving the stability of the socket wrench body 7 and solving the trouble of the staff.

The rubber sleeve 4 can play a protective role to prevent the staff from holding the handle 2 for a long time, causing friction and skin breakage on the palm.

[0028] The working principle of this utility model is: first, Figure 1 When the socket wrench body 7 is in the state of being retracted, the user can conveniently carry it with him. When the socket wrench body 7 needs to be used, the pull rod 10 is pulled, and the push plate 12 is pulled and retracted by the pull rod 10, and the push plate 12 is driven to retract and move by the push plate 12. When the retracted rod 13 is disengaged from the inner cavity of the socket 6, the limiting pressure of the socket wrench body 7 is eliminated. Then the user pulls the socket wrench body 7 to extend it, and the length of the socket wrench body 7 can be extended according to the user's needs. When the length of the socket wrench body 7 is adjusted, the user releases the hand pulling the pull rod 10, and the limiting pressure of the spring 11 is eliminated. The spring 11 can effectively utilize the reset elasticity to drive the push plate 12 to reset and move, so that the push plate 12 pushes the plug 13 to move, and the plug 13 is moved and inserted into the inner cavity of the socket 6, so as to avoid the socket wrench body 7 from loosening or shrinking during use, thereby improving the stability of the socket wrench body 7.
