TWI258406B - Improved separation prevention structure for a polygonal socket ratchet wrench - Google Patents

Abstract

This invention aims to provide an improved separation prevention structure for a polygonal socket ratchet wrench, for overcoming the defects found in the conventional ratchet wrench having a separation prevention structure that is difficult for manufacturing, easily deformable and damaged. To achieve the object, according to this invention, a lateral opening provided to a compartment for receiving the ratchet body in a wrench body is inwardly extended with a barrier. An opening formed by the barrier is slightly smaller than an opening of a claming seat of the ratchet wheel, so as to reduce manufacturing and assembling cost while preventing nuts from separating from the clamping seat.

V. INSTRUCTION DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to an improved anti-separation structure of a multi-inner-angle fixed ratchet wrench, which mainly utilizes a structure of a baffle to achieve easy assembly, structural stability and lifting. Practical effect. [Prior Art] According to the current popular DIY atmosphere in the home, and the domestic hand tools development system is quite mature and stable, regardless of product type or structural quality, it has been unanimously affirmed at home and abroad. In the past few years, the tool manufacturing industry has made it easier for the general consumer to use it.

'Therefore, various hand tools that are easy to operate or with humanized functions are also asked one after another. When the one end of the nut wrench wheel is provided with one piece, it has a shape to prevent 1 shape, when the shape is thin, or the inner edge of the process is left behind. After the efficiency of the screw, the firmware and the ratchet are required to be cut first. If the light is reduced in the step of the light, the baffle will be slipped and slipped. The utility model has the utility model, the baffle can be, however, but the inner edge is a force that is adjusted to accurately form the upper end of the ratchet. Further, the ratchet forms a difficulty at one end of the ratchet, and the spine is difficult. In the case of damage, the production cost is increased by the wheel and the large-format, such as the announcement of the main system to prevent the use of the ribs to avoid the ribs around the baffle, so as not to forge the rear board, if the board is slightly reduced, it will be difficult to make a ratchet The wrench ratchet prevention will be formed first. In the ratchet, the need for the ratchet will cause the inadvertent product to conform to the ratchet of the wheel wrench. Although the following structure is missing: the complex geometric spine Forged multicast polishing plate so shaped ratchet other complex 'also possible ratio of production to market demand.

V. Description of invention (2) ___ 2, the ratchet of the conventional use is _ Γ open, ^ ^ one end of the wheel forms a baffle, * ιν = two buckles on the pull head, and if at the end of the ratchet, the baffle, And continue to the country on the head, and the right way, this will increase the ratchet:: provide the screw anti-slip force to buckle the ratchet C-shaped buckle is easy to open: force 'and if used for a long time' In addition to the moving head, the formation of the fault r causes: the ratchet flies off during use. l L % can be used to inflict the inconvenience of the enemy. From the top; - ‘the use of the anti-destruction structure to the right to tell the truth to the need to improve. . Although the brother-in-law does not have practicality, it is actually added. [Inventive content] The main object of the present invention is to provide a multi-anti-detachment structure improvement, and the τ && angle-mouth ratchet wrench 4 is not easy to manufacture, and is easily deformed and damaged. Etc.;; with:;; = anti-detachment structure mouth, inwardly extending - baffle, and the shape of the board = side open § sea spine body clamping seat opening, so as to achieve the prevention of It can also reduce manufacturing and assembly costs. The towel dislocation clamping seat is as follows: the invention of the multi-inner angle fixed ratchet wrench, as a finishing discussion, so that the reviewing committee can obtain more of the invention;; structure; good understanding: and further, the baffle of the invention The system is integrally formed on the main body of the wrench, and the interior of the chamber is a cylindrical accommodation space. Therefore, the baffle plate at the end of the Rong j mountain does not cause manufacturing difficulties, and is far more complicated than the conventional one. The process of setting the baffle on the ratchet is easy, so the Z-interference can be eliminated. Sleepy on the k-shirt

Page 6 1258406 V. INSTRUCTIONS (3) 2. The effect of the C-shaped buckle on the structure strength of the ratchet. Therefore, the present invention is one, and it is quite worthwhile for the industry to deduce that the screw can be abutted against the baffle when the extra negative is too large, and the buckling can be prevented by the baffle. Therefore, the baffle of the present invention has an increase in the entire anti-detachment body (the wrench main chamber (1 2 ) extends a baffle (1 ratchet body 1), and the wrench and the ratchet are quite practical and The progressive invention is widely disclosed and disclosed to the public. [Embodiment] As shown in the first to fourth figures, the multi-corner fixed ratchet of the present invention mainly comprises a wrench body (10) wherein: the tooth (2 cap). By 12) less than the part of the outer baffle (end, more 2) when assembled into the above, the clamping seat edge happens to 13) can reduce the defense.

Structural improvement 2 0), body (10, the chamber 3), formed with (20) inner edge) one end of the head (1 1) is formed with a (1 2) - side opening circumference is inwardly extended The ratchet body (20) is accommodated. The outer peripheral surface is formed with a spine-clamping seat (2 2 ) for receiving the screw member, and the ratchet body (20) is accommodated in the chamber (located at the chamber port) The opening of the baffle (13) is slightly (2 2), so that the baffle (13) is traversed to the opening of the end of the holder (2 2 ) and will be placed on the wrench head Difficulties in the fabrication of one of the chambers (1 1 ), which in turn makes the holder of the present invention (the second nut can be separated from the opening thereof) and can be reduced in manufacturing and

1258406 The actual production of "the experience of more than ten years, the lack of problems is quite the result of the development, the principle of progress, the first limit of the content of the content, the progress of the first." $ to explain any form of the invention. Mingduojiao fixed spine for practicality and cost' and the disclosed knot has "new and more effective patent application for patent application in the promotion of national patent law, and please note that the invention is (4) The development of such products has been studied in the absence of the above-mentioned defects caused by the anti-separation structure. Therefore, the present invention is absolutely in line with the issue of the patent examination base: in the space of technological development, it is considered to have the only The invention is intended to be included in the spirit of the invention, and should be included in the intent of the present invention. The invention is improved in structural design and conforms to the innovative structure required for industrial development. "Structure", which is in full compliance with my regulations, is specifically affirmed according to law. The company of the ratchet wrench, for the solution of the conventional ratchet wrench, and the present invention is based on the actual improvement of the effect, and this is the preferred embodiment which is slightly modified in technology as described in the second page of the bureau. It is not a system. Therefore, if there is any modification or change in the aspect, it is still the protection of the wheel wrench. It is indeed a complete invention. It should be undoubtedly considered. The CCP of the application for the advancement of the patent is reviewed at an early date, and
