TWI224538B - Structure improvement on extension bar of tool - Google Patents

Abstract

The present invention relates to a structure improvement on extension bar of tool, wherein an extension bar that is removably engageable with a D-end wrench and a socket has a bottom end defining a receiving space in which a magnetic attraction device is accommodated. The magnetic attraction device comprises a spring, a magnet, and an extendible structure consisted of large, medial, and small tubes telescoping each other. By means of the extendible telescoping structure of the large tube with knurling formed on an outer circumference, a secure coupling can be established between the magnetic attraction device and the extension bar. By means of the removable engagement design of the extension bar, together with socket of different sizes, attraction of a loosened threaded member can be effected, which improves the drawbacks of increased material costs and slow assembling speed occurring in the conventional socket structure which includes a spring and a magnet installed inside the socket to realize attraction of threaded member.

1224538 五、發明說明（1) 【技術領域】 本發明係有關於一種工具接桿，尤指一種組裝簡易之 磁吸工具接桿結構。 【先前技術】 按，一般習知之套筒結構，在鬆脫螺合件時，螺合件 乃會自行脫落掉出，此種設計實會導致工作上之不便；業 界為解決扳鬆之螺合件可與套筒呈吸附關係，故將套筒内 部設有一彈簧及一磁性體，以利其扳鬆螺合件時，利用磁 性體之磁吸特性，將螺鬆拆卸之螺合件順勢吸附在套筒内 ，同時並達到螺合件第一時間取出之優勢。 然，此種方式雖甚為方便，但套筒之尺寸繁多，如此 ，在每個套筒内皆設有一彈簧及一磁性體之設計方式，在 成本考量上即顯得不敷經濟效益，且於每個套筒内裝設一 彈簧及一磁性體亦會造成套筒整體之組裝速度緩慢之缺點 ，為此，業界便又改良出如附件一之套筒結構。 其中觀之附件一（附件一係台灣專利公告之4 8 3 3 6 1號『套筒扳手之結構改良』），其係藉由一螺絲而令 套筒與套筒扳手呈一固設關係，再於套筒底緣設有一穿孔 ，該穿孔係可供一内具磁性體之定位套穿卡，如此，當欲 更換不同尺寸之套筒時，則僅需將套筒底緣之定位套取出 ，再行置入另一套筒底緣之穿孔内，即可達到不同套筒皆 可使用之功效，以改善上述結構需於每個套筒内設有一彈 簧及磁性體所產生之成本及組裝上之缺失； 然，此種結構在使用上亦有如下所揭之缺失：1224538 V. Description of the Invention (1) [Technical Field] The present invention relates to a tool post, especially a magnetic tool post structure with simple assembly. [Previous technology] According to the conventional sleeve structure, when the screwing part is loosened, the screwing part will fall off by itself. This design will cause inconvenience in work. The part can be in an adsorption relationship with the sleeve, so a spring and a magnetic body are provided inside the sleeve to facilitate the loosening of the screwed part, and the magnetically attracted feature of the magnetic body is used to disassemble the screwed part of the screwed loosen. In the sleeve, the advantage of taking out the screwing part at the same time is achieved. Of course, although this method is very convenient, the sleeves have various sizes. In this way, a spring and a magnetic body are provided in each sleeve, which is not economically efficient in terms of cost considerations. The installation of a spring and a magnetic body in each sleeve will also cause the disadvantage of the slow assembly speed of the entire sleeve. For this reason, the industry has also improved the sleeve structure as in Annex 1. Attachment 1 of the concept (Annex 1 is the structure improvement of the socket wrench of Taiwan Patent Bulletin No. 4 8 3 3 6 1), which uses a screw to make the socket in a fixed relationship with the socket wrench. A perforation is provided at the bottom edge of the sleeve. The perforation can be used for a positioning sleeve with a magnetic body inside. In this way, when replacing sleeves of different sizes, it is only necessary to take out the positioning sleeve at the bottom edge of the sleeve. , And then put it into the perforation at the bottom edge of another sleeve to achieve the effect that different sleeves can be used, in order to improve the cost and assembly caused by the need to have a spring and a magnetic body in each sleeve. However, this structure also has the following defects:

1224538 五、發明說明（2) 此種習用套筒扳手之結構改良，當欲使用不同尺寸之 套筒時，則需先將固設套筒之螺絲拆卸後，再將套筒底緣 之定位套取出並置入另一尺寸之套筒底緣，如此繁雜之更 換程序，實會導致定位套更換耗時費力之缺點。 再，參看附件二（附件二係台灣專利公告之4 7 8 4 3 3號『手工具吸附結構』），其主要係利用一扳手工具 ，該扳手工具係可供開口扳手或梅花扳手套卡扳動，且該 扳手工具一端設有一容置室，該容置室内係可容設有一彈 簧及一具磁性體之套體，最后，再藉由沖壓加工方式，令 扳手工具之容置室形成一抵緣，藉該抵緣而可防止容設在 容置室内之彈簧及套體脫落； 使用時，係將扳手工具穿設在套筒一端，再將套筒另 一端套卡一螺合件，再藉由一開口扳手（或梅花扳手）旋 動扳手工具，進而使套筒可一併旋鬆螺合件，當螺合件鬆 脫時，可透過扳手工具容置室内具磁性體之套體，而達到 螺合件之吸附功效。 上述習用之手工具吸附工具，雖可利用一活動套接之 扳手工具，而達到配合不同尺寸套筒使用之功效，但此種 習用之手工具吸附工具，需利用沖壓方式將扳手工具成形 有一抵緣，以防止彈簧及套體脫落；一般係知沖壓加工之 下壓力道相當之大，故欲令結構體積較小之扳手工具容置 室成形有一抵緣，在機械力道之控制上即需特別小心，如 稍有不慎即會因沖壓力道過大或沖壓準心偏差，而導致扳 手工具整體外觀變形，進而造成扳手工具不良率大增之缺1224538 V. Description of the invention (2) The structure of this conventional socket wrench is improved. When using sockets of different sizes, the screws fixing the sockets must be removed first, and then the positioning sleeve at the bottom edge of the sockets must be removed. Taking out and placing the bottom edge of the sleeve of another size, such a complicated replacement procedure will actually lead to the disadvantage of time-consuming and laborious replacement of the positioning sleeve. Then, please refer to Annex II (Annex II is Taiwan Patent Publication No. 4 7 8 4 3 3 "Hand Tool Suction Structure"), which mainly uses a wrench tool, which can be used for open-end wrenches or plum wrenches. And one end of the wrench tool is provided with an accommodating chamber. The accommodating chamber is capable of accommodating a spring and a sleeve body with a magnetic body. Finally, the accommodating chamber of the wrench tool is formed by a stamping process. The abutment edge can prevent the spring and the sleeve body contained in the accommodating chamber from falling off by using the abutment edge; when in use, the wrench tool is put on one end of the sleeve, and the other end of the sleeve is sleeved with a screwing piece. Then use an open-end wrench (or plum wrench) to rotate the wrench tool, so that the sleeve can be loosened together with the screw. When the screw is loose, the cover can be housed with a magnetic body in the room through the wrench. , And achieve the adsorption effect of the screw. Although the conventional hand tool suction tool can use a movable socket wrench tool to achieve the effect of using different sizes of sleeves, this conventional hand tool suction tool requires punching to form the wrench tool to a certain extent. In order to prevent the spring and the sleeve from falling off, it is generally known that the pressure channel under the stamping process is quite large, so if the structure space of the wrench tool housing with a small structure is formed, an abutment edge must be formed, and the control of the mechanical force needs to be special Be careful, if you are not careful, the overall appearance of the wrench tool will be deformed due to the excessive punching pressure or the misalignment of the punching center, which will cause the defect rate of the wrench tool to increase greatly.
