Description

Technical Field

[0001] The utility model relates to the technical field of sleeves, and in particular to a sleeve with a labor-saving structure. Background Art

[0002] Socket wrenches are generally called sockets. They are composed of multiple sockets with hexagonal holes or dodecagonal holes and are equipped with handles, connecting rods and other accessories. They are particularly suitable for turning bolts or nuts with very narrow positions or deep recesses. The nut end or bolt end is completely lower than the connected surface, and the diameter of the recessed hole cannot be used for open-end wrenches, adjustable wrenches and plum blossom wrenches, so socket wrenches are used. In addition, due to space limitations on bolt parts, only socket wrenches can be used. Sockets are divided into metric and imperial systems. Although the inner concave shape of the socket is the same, the outer diameter, length, etc. are designed for the shape and size of the corresponding equipment. There is no unified national regulation, so the design of the socket is relatively flexible and meets the needs of the public.

[0003] Most of the existing socket wrenches are designed to be rotated by directly holding the handle by hand, but the human arm strength is limited, and it is very laborious and inconvenient to manually turn the wrench, which greatly reduces the practicality of the device. Therefore, we provide a socket with a labor-saving structure to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a sleeve with a labor-saving structure, comprising a sleeve body 1, a fixing rod 2 is arranged on one side of the sleeve body 1, a telescopic component 3 for adjusting the length is installed between the sleeve body 1 and the fixing rod 2, a labor-saving component 4 for increasing the torque is installed at one end of the fixing rod 2 away from the sleeve body 1, the labor-saving component 4 comprises a mounting seat 41, and the mounting seat 41 is fixedly connected to the fixing rod 2, a rotating rod 42 is hingedly installed on one side of the mounting seat 41, and a damping pad 46 is installed at the hinged joint between the mounting seat 41 and the rotating rod 42, which can increase the friction of the rotating rod 42 when rotating, so as to better limit the rotating rod 42, and the rotating One end of the rod 42 is connected to a grip rod 43, and a rubber sleeve 44 is sleeved on the surface of the grip rod 43. In order to make it more comfortable to grip, the surface of the rubber sleeve 44 is connected to a protrusion 45. In order to increase the friction during contact, a handle 5 is installed at the end of the mounting seat 41 away from the fixed rod 2. This structure makes it possible to press the grip rod 43 from the side to drive the fixed rod 2 to rotate, and the fixed rod 2 drives the sleeve body 1 to rotate, which can increase the torque and make the rotation more labor-saving. The end of the mounting seat 41 close to the handle 5 is connected to a limit plate 47. In order to limit the rotation angle of the rotating rod 42, the rotating rod 42 can be rotated more quickly to a perpendicular state to the fixed rod 2.

[0021] As an implementation method in this embodiment, Figure 3 As shown, the telescopic assembly 3 includes a movable groove 31 and a locking assembly 6. The movable groove 31 is opened at one end of the fixed rod 2 close to the sleeve body 1. A movable rod 32 is slidably installed in the movable groove 31, and the outer end of the movable rod 32 is fixedly connected to the sleeve body 1. The movable rod 32 is limited and fixed in the movable groove 31 by the locking assembly 6. This structure makes it possible to extend or shorten the length of the fixed rod 2 and the movable rod 32 as needed, which is more convenient.

[0022] As an implementation method in this embodiment, Figure 3 and Figure 4As shown, the locking assembly 6 includes a slide groove 61 and a limiting hole 64. The slide groove 61 is opened on the surface of the movable rod 32. A spring 62 is installed on the lower side of the slide groove 61. A limiting block 63 is slidably installed on the upper opening of the slide groove 61. The limiting holes 64 are equidistantly arranged and opened on the inner wall of the movable groove 31. The limiting block 63 is inserted in the limiting hole 64. This structure makes it possible to lock the position of the movable rod 32 in the movable groove 31, so that the adjusted length can be fixed. The surface of the fixed rod 2 is equidistantly arranged with grooves 65, and the grooves 65 are all opened at the upper opening of the limiting hole 64, in order to make it more convenient to press the limiting block 63 into the slide groove 61.

[0023] Working principle: If you need to remove the bolt, you only need to adjust the length of the device according to the depth of the bolt, press the end of the limit block 63 into the limit hole 64 by pressing the end of the limit block 63, and then pull the movable rod 32 to slide in the movable groove 31. At this time, the limit block 63 will be pushed and squeezed into the slide groove 61 to compress the spring 62 until the movable rod 32 slides to the appropriate position, and then the limit block 63 corresponds to the appropriate limit hole 64. At this time, the limit block 63 will be pushed out of the slide groove 61 through the restorative force of the spring 62 and inserted into the limit hole 64. The length can be fixed here, and then the rotating rod 42 is rotated, and the rotating rod 42 drives the grip rod 43 to rotate until the rotating rod 42 is rotated to a vertical state with the fixed rod 2. Finally, the sleeve can be When the sleeve body 1 is sleeved on the bolt, the rubber sleeve 44 can be held by hand and the gripping rod 43 can be pressed downward, the gripping rod 43 can drive the rotating rod 42 to rotate, the rotating rod 42 drives the fixed rod 2 to rotate through the mounting seat 41, the fixed rod 2 drives the movable rod 32 to rotate, the movable rod 32 drives the movable groove 31 to rotate, and the movable groove 31 drives the sleeve body 1 to rotate, so that the torque can be increased, so that the sleeve body 1 drives the bolt to rotate to make it easier to loosen, and finally the handle 5 can be held by hand to drive the fixed rod 2 to rotate until the bolt is removed. In addition, when not in use, the movable rod 32 can be retracted into the movable groove 31, and the rotating rod 42 can be rotated to be parallel to the fixed rod 2, so that the gripping rod 43 can be folded up, thereby saving more space when stored, greatly increasing the practicality of the device.

[0024] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
