The conventional sleeve has a working end and a joint end, and the working end is provided with a screw or a bolt for connecting a sleeve wrench, but the joint end of the existing sleeve has two forms, the first type The outer cross section is hexagonal and the inner circumference is rounded. The second type is circular in the outer circumference and the inner circumference is quadrangular. The existing sleeve wrench has two forms, one is for the first type. a sleeve form having a groove and the groove has a hexagonal cross section, and the other is a quadrangular projection in cooperation with the second sleeve form, if the user wants to use the first sleeve, but uses If there is only a socket wrench with a square-shaped bump on hand, then it is impossible to disassemble the work, or if the user wants to use a socket wrench with a hexagonal groove and only a second sleeve on the hand, so It is impossible to do the disassembly and assembly work, because the sleeve and the socket wrench do not necessarily cooperate with each other, which may cause trouble for the user.

Therefore, the purpose of the present invention is to provide a sleeve that can be used with different types of socket wrenches to achieve ease of use.

The present invention provides a sleeve comprising a working end and an engaging end, the working end and the engaging end are respectively located at two ends of the sleeve, the working end comprises a receiving groove, and the receiving groove is disposed at The working end has an opening facing outward, and the engaging end comprises an inner corner hole, an outer convex corner, a first bead portion and a second bead portion, wherein the inner corner hole is located at an inner annular surface of the engaging end, the inner corner The peripheral portion of the hole has a quadrangular shape, and the outer convex angle is located outside the joint end. The outer peripheral corner has a hexagonal cross section, and the first bead portion is disposed on each side of the inner corner hole, and the second bead ring is formed. Located at the periphery of the outer convex corner.

In the sleeve, the accommodating recess further includes a plurality of teeth, and the plurality of teeth are annularly arranged in the accommodating recess.

In the sleeve, the inner corner hole is continuous with the receiving groove.

In the sleeve, the sleeve, the inner corner hole further comprises four grooves respectively disposed at respective angular positions of the inner corner holes and extending longitudinally with respect to the joint ends.

In the sleeve, the joint end further includes a stop portion disposed on a periphery of the outer lobe and not overlapping the second bead portion.

By the above technical means, the at least the utility of the present invention is that the sleeve of the present invention can be matched with different types of socket wrenches, thereby achieving the convenience of using the lifting sleeve.

Referring to FIG. 1 to FIG. 3, in the first preferred embodiment of the present invention, the sleeve 1A includes a working end 10A and an engaging end 20, and the working end 10A and the engaging end 20 are respectively located on the sleeve 1A. The receiving end 12A includes a receiving recess 12A, and the receiving recess 12A is disposed at the working end 10A and the opening is outward.

Preferably, the tooth portions 122A are provided with twelve, and the twelve tooth portions 122A are equally arranged annularly in the accommodating recess 12A. The twelve tooth portions 122A can make the workpiece head cross-section different angles. The workpiece is arbitrarily inserted and locked in the accommodating recess 12A, and one corner of the polygonal workpiece is locked between the two adjacent tooth portions 122A for limiting. The accommodating recess 12A can also be used for engaging. The joint end 20 includes an inner corner hole 22, an outer corner 24, a first bead portion 26, a second bead portion 28 and a stop portion 29, and the inner corner hole 22 is located at the joint end. The inner corner hole 22 has a quadrangular cross section, and the inner corner hole 22 and the accommodating recess 12 can penetrate therethrough, and the inner corner hole 22 can include four The groove 222 is disposed at each of the angular positions of the inner corner hole 22, and extends longitudinally relative to the joint end 20, and the outer corner 24 is located outside the joint end 20, and the outer corner 24 The first bead portion 26 is disposed on each side of the inner corner hole 22 for engaging with the steel ball of the existing socket wrench quadrangular lug joint, and the second bead portion 28 is ring-shaped. The outer peripheral corner 24 is used for engaging with the C-shaped elastic member of the existing sleeve hexagonal groove joint, because the sleeve 1A of the present invention has the inner corner hole 22 and the outer convex angle 24 at the same time, so that it can be matched Different types of socket wrenches are convenient for the user to use, and the anti-slip portion 29 is disposed on the periphery of the outer lobe 24 and does not overlap the second bead portion 28.

Referring to FIG. 4 and FIG. 5, in the second and third preferred embodiments of the present invention, the structure of the sleeves 1B, 1C is the same as that of the first preferred embodiment shown in FIG. 1, but the working end 10B, 10C It can be of different sizes and shapes, so that the sleeves 1B, 1C of different working ends 10B, 10C can be selected for different workpieces only when used.

Referring to FIG. 6 to FIG. 7 , the preferred embodiment of the present invention uses the sleeve 1A as an example: 1. Using a socket wrench A, the socket wrench A has a square-shaped bump, the convex A steel ball is disposed on the block, and the inner corner hole 22 of the sleeve 1A is sleeved on the protrusion of the socket wrench A, and the steel ball will be caught in the first bead portion 26 of the sleeve 1A, so that the sleeve 1A can be The sleeve wrench A is firmly engaged, so that the sleeve 1A can be rotated as the socket wrench A rotates to lock or loosen the workpiece. 2. Using a socket wrench B, the socket wrench B has a hexagonal groove, a telescopic groove and a C-shaped elastic member, and the telescopic groove ring is disposed on the periphery of the socket end of the socket wrench B. And the telescopic groove is in communication with each of the angles of the hexagonal groove, the C-shaped elastic member is disposed in the telescopic groove and partially protrudes from the hexagonal groove, and the outer corner of the sleeve 1A is 22 Installed in the recess of the socket wrench B, the C-shaped spring member will be caught in the second bead portion 28 of the sleeve 1A, so that the sleeve 1A and the socket wrench B can be firmly engaged.

Referring to FIG. 7 to FIG. 9 , the first preferred embodiment of the present invention is engaged with the third preferred embodiment. When the socket wrench B is mounted with the sleeve 1A, the working end 10C of the sleeve 1C can be used. Engaging the engaging end of the sleeve 1A, the outer corner 24 of the sleeve 1A is mounted on the receiving recess 12C of the sleeve 1C, and the outer corner 24 of the sleeve 1A is limited to the tooth portion 122C to make the sleeve The barrel 1A is firmly engaged and does not rotate relative to each other. Thus, the length of the sleeve can be increased by the manner of engagement, that is, when the diameter of the receiving groove of the sleeve 1C is larger than the diameter of the working end 10C, and the tooth portion 122C thereof can be The other end of the working sleeve 10C of the same sleeve 1C is engaged with the lobes 24, and the sleeve 1C of the same structure can be sequentially engaged according to the sleeve 1C, so that the overall working length of the sleeve can be increased to meet the requirements of the work.
