Sleeve structure easy for recognizing square hole size

Abstract

The invention discloses a sleeve structure which is easy for recognizing a square hole size. The peripheral edge of the sleeve additionally has a size recognizing structure of a square hole for being connected with a drive tool in addition to a size recognition structure of an actuating workpiece; the recognizing structure is provided with at least one recognizing part; at least one axial marking block or at least one radial marking block or a mixed form of the two blocks is arranged in the recognizing part; the two blocks both have rectangular structures; the axial marking block represents 0.3175cm (1/8inch), and the radial marking block represents 2.54cm (1inch); and the blocks in the recognizing part are convenient for a user to rapidly recognize the square hole size of the sleeve so as to select the drive tool of a square head with the corresponding size in shortest time and rapidly connect and actuate the workpiece accommodated in the sleeve, thereby effectively saving the lead time for preparing the tool, reducing working cost per hour and improving economic benefits.

Description

technical field [0001] The invention relates to a sleeve structure for easily identifying the size of a square hole, which is related to hand tools. Background technique [0002] Currently common sleeves, such as figure 1 As shown, there is usually a multi-angle hole for accommodating the actuating hole 11 and a connecting end 12 in the form of a square hole, wherein the actuating hole 11 is used to accommodate a workpiece 91 of a corresponding size, and the connecting end in the form of a square hole 12 can be used in conjunction with the driving tool 92 of the corresponding shape and the size of the square head 920, such as a wrench or an extension rod. In order for the user to identify the size of the workpiece 91 that the sleeve 10 can drive, the size is usually engraved on the surface of the sleeve 10 The identification structure 13, the sleeve 10 is directly engraved with Arabic numerals and units of size on the periphery of the outer surface for identification. Altho...

[0002] Currently common sleeves, such as figure 1 As shown, there is usually a multi-angle hole for accommodating the actuating hole 11 and a connecting end 12 in the form of a square hole, wherein the actuating hole 11 is used to accommodate a workpiece 91 of a corresponding size, and the connecting end in the form of a square hole 12 can be used in conjunction with the driving tool 92 of the corresponding shape and the size of the square head 920, such as a wrench or an extension rod. In order for the user to identify the size of the workpiece 91 that the sleeve 10 can drive, the size is usually engraved on the surface of the sleeve 10 The identification structure 13, the sleeve 10 is directly engraved with Arabic numerals and units of size on the periphery of the outer surface for identification. Although such a representation can provide the user with a clear identification of the size of the drivable workpiece 91 of the sleeve 10, And this one only marks the structure that identification structure 13 can drive workpiece 91 size, does not see then for the size that this square hole connecting end 12 can connect drive tool 92 square heads 920, so select the driving that is connected with this square hole connecting end 12 for use The tool 92 cannot be known immediately, so it is difficult to immediately distinguish the correct size when selecting the driving tool 92, which causes confusion and inconvenience in selection, and then prolongs the time for preparing the driving tool 92, resulting in the use of tools during the overall operation. The inconvenience and efficiency are not obvious, but the overall production cost is invisibly increased. In view of this, the inventor has devoted himself to research and further conceived, and finally invented a sleeve structure that is easy to identify the size of the square hole, which can shorten the identification time. The time to drive the tool can thus shorten the overall use and processing time
