The increase of the 3 line of the handle will cause the negative operation of the manufacturer. M308828 8. New description: [New technical field] The author is a wrench, especially a semi-tailed wrench with a hollow grip. [Prior Art] The development of hand tools is a fairly mature industry, and each wrench manufacturer is pursuing excellence in the pursuit of a design that is easier to use, easier to manufacture, and more cost effective. The grip of the wrench is solid, improved to hollow, and evolved into a hollow, tailless design, but it still has all kinds of defects. Therefore, the creator has been engaged in the research and development of hand tools for many years, and hopes to develop a real A grip that loses weight and has sufficient strength. First of all, the solid body is formed by a solid body, and the whole body is hot forged by solid iron. The weight is quite heavy, especially the large-sized wrench is easy to cause a burden on the user. When the user holds for a period of time, It is easy to increase fatigue and reduce its working efficiency. In addition, the solid iron in the forging process: easy to cause stress towel, the series of f ♦ weaker, and the current material into a forest break, the financial heart to make a substantial increase in cost of expenditure. Participating in the eleventh, as a one-piece solid wrench, there is a lack of the above. The head of the wrench, the neck 2 and the grip 3, are formed by a forging shape, and the whole riding heart f is mixed with the M308828 of the county, which accelerates the wear and tear of the user's physical strength and relatively reduces the efficiency of the work. It is necessary to develop and improve. 'Further' has a hollow-shaped wrench for the sake of weight reduction and its strength. The wrench looks like a m but has a hollow shape inside the handle. This kind of red-red heart wrench is in weaving or New Zealand. The danger of explosion and explosion. #..., 俊采 ^ 艮 The danger of the above-mentioned hollow wrench has two, ·,, tail 4 grip w}·. See US Patent Counselor 2nd (4) / 〇 15 4825 A1 "face LE bribe ET _ch". The handle 30 and the chat η are pivotally engaged, and the twist is obviously from. Further, the handle is hollow inside, and a plug is provided at the tail. The grip, the middle of the open, in the process of processing, must go through a number of manufacturing procedures, cleaning - surface treatment ~ inspection ... various processes, the phenomenon of the age, the plugging Γ take the Γ 制 process, then often The occurrence of the hollow grip 30 during the process is due to any support at the end of the grip 3 (), and the occurrence of the recessed Si becomes a defective product, which increases the cost of the manufacturer. ',,,, and the above-mentioned lacks' have been designed to have a hollow design with a covered tail. See US Patent No. 6070499, "RATCHET WRENCH HAVINO TW〇M0DES 〇p," but this type of grip is a four-piece combination shouting, the grip is internally provided with a rotating member 24, and the grip 11 is simultaneously threaded - Kit 12, then check 29 fixed. There is a lack of weight in this type of grip. M308828 In view of this, the creator has been trying to solve the problem of dividing money for many years, and hopes to create a practical left-night development and improvement, and finally carefully design the tongue-handler's ability to overcome the body of the wrench body = type: loss ^ spine Creation of novelty and progress. [Embodiment] The technical problem of the creation of the "semi-tailed wrench with a hollow grip" is that the 'solid wrench is heavy and the material cost is high, while the hollow wrench is used in the heat treatment and plating process. Public security dangers. The above-mentioned wrench is necessary to add 1's to the above-mentioned problems, and is committed to research and development to create a kind of material that can save material, is light in weight, and does not cause danger during heat treatment or electro-recording, and can have sufficient strength. The handle does not cause a depression when applied or held. The semi-tailed wrench with a hollow grip of the present invention comprises a head, a second neck and a grip. The neck has a first end and a second end, wherein the first end is in contact with the head. The handle includes a grip portion, a joint portion, a tail portion and a space, the joint portion is in contact with the second end of the neck portion, and the tail portion is bent in an arc to form a hole, and the space is implemented in the handle The inside of the handle is connected to the hole of the tail portion, and a cover member covers the hole of the tail of the handle. The handle has a weight-reducing effect by the space in the handle, and the curved person folds the handle to withstand a large holding force, and is covered by the cover member, so that the handle is The structural strength is even stronger. M308828 [Embodiment] Regarding the technology, means and sisters of the present invention, the preferred embodiment is used in conjunction with the material, and the application is not limited by this structure. Referring to Figures 1 to 3, the three-dimensional appearance and three-dimensional exploded view of the creation are shown. The semi-tailed wrench with a hollow grip includes a ~3 handle with an i handle. A first receiving portion is formed in the head portion 1Q. The third receiving portion n is formed in the neck portion 2, and the first portion U, 12, and 21 are connected to each other. The shackle can be set to 4° to drive the screw lock member, and the third portion is replaced by the spine scale 4G, and the first portion 20 connects the first & , 篦 被 被 被 被 被 被 被 被 被 被 被 被 被 被 被 被 被 被 被 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 9 The miscellaneous handle 30 is connected. The 12 series is implemented on the second two = the Xth head line 14'. The head neckline portion 20 is in contact with the handle 3M (four) the portion 21. The handle 30 has The two ends of the joint portion 31 of the smaller diameter are respectively the outer end of the joint portion 32, the second end 22 of the joint portion 32, and the second end 22_ is tapered. The joint between the one-like holding portion 31 and the joint portion 32 is the secret of the meaning. The _33 is folded into (four) to form an axial hole tear. 8 M308828 " The inner handle 30 defines a space 34, the space 34 The tail portion 33 is open and opens to the joint portion 32 to be closed. The handle 30 has the effect of reducing the weight. The handle 30 can be implemented as a hollow tube, which can reduce the production cost. Generally hollow = the hollow inside of the tube is formed due to the material saving and weight reduction, but the wall is thin The factor is held by the grip portion 31, and the wrench is biased to drive the screw member, and the grip portion 31 is biased too much to cause an inward depression, and the creation is formed in the tail portion 33 with an arc-shaped bend. The fold 332 is inwardly retracted so that the tail catch 33 can withstand a large force without being recessed inward. When the grip portion 31 is biased, the force will be dispersed to the arcuate bend 332. Two of the handles 30 provide the handle with weight reduction, and the curved bend 332 allows the handle 30 to withstand a large grip. The space 34 in the handle 30 can be placed. The tool head or screw lock, such as a screw or nut, allows the operator to have a "storage space" without the need to place a small part such as a talk. A cover 50 has a large diameter 51 at one end and a small diameter 52 at the other end. The small diameter 52 of the cover member 50 is detachably coupled to the hole 331 of the tail portion 33, and the handle 30 is closed to make a talk. The large diameter 51 is attached to the arcuate bend 332, and one side is exposed to the outside. The structural strength of the tail portion 33 of the handle 30 is enhanced by the cover of the cover member 5〇. A schematic diagram of the safety ratio between the rider 2α and the head 1G. The wrench is for the operator to drive the screw lock. In the embodiment, the head 10 is provided with a ratchet member 40 for pulling a screw or a nut. The neck to the neck 20 is limited by the weight reduction and the upper space of the operation, and the neck M308828 20 is designed to be tapered. When the screw lock is driven, the neck 2 〇 is in contact with the head 10 It is extremely easy to damage the shearing force due to the wrench. A wrench with insufficient strength can easily break in the neck. Therefore, the creator has been researching and improving the experience of hand tools for many years, and has tested the ratio of the head 1 〇 to the neck 2 ,, which can surely make the wrench not break. The length of the neck 20 is defined as the distance from the headline 14 to the handlebar 25. The length of the head 1 is defined as the distance from the end of the head 1 至 to the headline 14 . When the length of the neck portion (A) > the length of the head portion 10 (B)/2, that is, the length of A > B/2, it is possible to surely prevent the neck portion 2 from being broken due to excessive shearing force. Figure 5 and Figure 6 show the schematic diagram of the second embodiment of the creation. The wrench $ contains the head 1 〇, the neck 2 〇 and the handle 3 〇. The head ι includes the first accommodating portion 11 and the second accommodating portion 12, wherein the first accommodating portion can sleeve the receiving member. The head 1G is gradually formed into a neck of the κ tubular shape, and the third receiving portion 21 is formed in the neck portion 20, and the first end 23 of the neck portion 2 has a larger diameter and the head portion 1〇 is connected, and the second end 24 is a neck portion 20 and is in contact with the grip 3〇. The space 34 in the handle 30 is open at the tail portion 33, and the joint portion 32 is also open and strong. The body is designed to be the right sister, so that the handle has the design. Reduce the effect of resetting. ^ α · N hangs the two examples of the application. The head has the first accommodating portion 11 and the second accommodating portion 12, and the head portion 20 is formed with a blind hole 26 in the axial direction. The grip 30 is the same as the second example of the disc. Wei blind hole 2H head through the handle 3G Lang
