One of the first standard range and the second standard range is a metric size range, and the other is an English size range; the first standard range includes a first upper limit and a first lower limit, and the second standard range includes a second upper limit and a second lower limit. When the first lower limit value is between the second lower limit value and the second upper limit value, setting the size of the target looping not to be smaller than the first lower limit value and not to be larger than at least one of the first upper limit value and the second upper limit value; and when the first lower limit value is greater than the second lower limit value and the second upper limit value, setting the size of the target looping to be not less than the first lower limit value and not greater than the first upper limit value. The hand tool body 10 is provided with a sleeve opening 11 and a plurality of side edges 12 which surround the sleeve opening 11, and the distance between two radially opposite side edges 12 corresponds to the size of the target sleeve opening, so that the sleeve opening 11 can be simultaneously suitable for fastening pieces of metric and English ruler gauges, and is convenient to process, wide in application range and good in operation stability.
In this embodiment, the first standard range is the imperial size range, and the second standard range is the metric size range; taking the dimensions of the english 11/16 "inch and 17 mm metric as an example, the english dimension range conforming to the standard is 17.51 mm (the first lower limit value) to 17.76 mm (the first upper limit value), the metric dimension range conforming to the standard is 17.05 mm (the second lower limit value) to 17.30 mm (the second upper limit value), and the target socket dimension can be set between 17.51 mm and 17.76 mm (e.g., 17.67 mm), whereby the socket 11 of the hand tool conforms to the english dimension range and can be used for fasteners of the 11/16" inch, and can be used for fasteners of the 17 mm close to the metric dimension range, and the manufacture is facilitated without additional processing.
Preferably, when the target cuff size corresponds to the first standard range and does not correspond to the second standard range, the difference between the target cuff size and the second lower limit value is not greater than 0.8 mm; when the first lower limit value is larger than the second lower limit value and the second upper limit value, the difference between the first lower limit value and the second upper limit value is not larger than 0.4 mm, so that the size fall is avoided from being too large to ensure that the fastening piece can be stably abutted and driven in a corresponding size range. It is particularly noted that the manufacturing method of the hand tool is to configure the distance between two radially opposite sides of the socket to conform to the target socket size, which is selected by the above-mentioned manner, so that the same two sides can abut against the fastening members of different sizes during operation, and the sides do not need to be additionally processed or configured in a special shape, thereby providing stable contact, the fastening members are not easy to slip and wear, and the using effect is good.
The manufacturing method of the hand tool is further provided with a first size mark 20 corresponding to the metric size range and a second size mark 30 corresponding to the English size range on the hand tool body 10, wherein the first size mark 20 and the second size mark 30 respectively comprise at least one of characters, numbers and patterns, as shown in fig. 1, and the first size mark and the second size mark are convenient for a user to select. Preferably, the manufacturing method of the hand tool further comprises at least one identification structure 40 disposed on the hand tool body 10, and when the target socket size corresponds to the metric size range, the first size mark 20 is provided with the identification structure 40; when the target cuff size corresponds to the english size range, the second size mark 30 is provided with the identification structure 40, so that the user can identify the standard size of the cuff 11. In the present embodiment, the at least one identification structure 40 includes a first identification portion 41 corresponding to the first size mark 20 and a second identification portion 42 corresponding to the second size mark 30; the first identification portion 41 and the second identification portion 42 can be, for example, a circular, oval or polygonal pattern, respectively. When the target cuff size corresponds to one of the metric size range and the english size range and does not correspond to the other of the metric size range and the english size range, the first identification portion 41 is different from the second identification portion 42, such as the hexagonal frame and the circular frame shown in fig. 1, and the first identification portion 41 and the second identification portion 42 have different shapes. Therefore, the user can easily know that the size of the sleeve opening 11 conforms to the British size range of 11/16' inch and can also use the metric size range of 17 mm. In other embodiments, the at least one identification structure may also include a pattern, a concave-convex structure, a color block, a text color, and the like, for example, the first and second marking portions are red patterns if they meet the standard range, and green patterns if they do not meet the standard range; the first and second marking portions may have a circular frame for the standard range, or no frame for the standard range, for identification.
The manufacturing method of the hand tool can preferably further form a plurality of notches 13 communicated with the looping 11, and each notch 13 is located between two adjacent sides 12, so as to facilitate the sleeving of the fastening piece and prevent the corners of the fastening piece from being worn. Preferably, each side 12 is a continuously extending flat section, and a width of each side 12 defining the space is not less than a width of another of the plurality of sides 12 for stable abutment against the fastener.
Referring to the second preferred embodiment shown in fig. 3, when the first lower limit value is between the second upper limit value and the second lower limit value, the target cuff size is between the first lower limit value and the second upper limit value. In this embodiment, the first standard range is the metric size range, and the second standard range is the english size range; taking the size of english 5/8 "inch and metric 16 mm as an example, the english size range conforming to the standard is 15.91 mm (the second lower limit value) to 16.16 mm (the second upper limit value), the metric size range conforming to the standard is 16.05 mm (the first lower limit value) to 16.27 mm (the first upper limit value), and the target cuff size can be set between 16.05 mm to 16.16 mm (e.g., 16.15 mm), so that the cuff 11a conforms to both the english size range and the metric size range, and is suitable for various sizes and convenient use. When the target cuff size corresponds to the metric size range and the English size range, the first identification portion 41 and the second identification portion 42 have the same shape, which indicates that the cuff 11a conforms to two specifications and is suitable for the corresponding fastening member. It is understood that the hand tool body 10a may be provided with a plurality of sockets 11a,11b, and the shape, specification and size of the sockets 11a,11b may be the same or different according to the requirement.
