Description

V. Description of the invention (1) Description of the invention The tool is connected when it is fixed or secure. For example, the four-convex shape of the bolt is difficult for most tools only by the known difficulties. The invention is important. According to the invention, the subject matter of the connector is to be solved. The connector is interposed. If the fitting or work piece, a component. Therefore, the center of the work piece is easy to hold when not in use. When installing, it is often necessary to borrow a job. When inserting, it must be connected—the tool has a limited insertion, which is suitable for tool to tool inconvenient locations. This problem is resolved by one. The present invention's meaning is to pick up the torque when inserting the screw and the axis is inconsistent when the torsional torque is transmitted, so that a tool and a screw element with a summary can drive the above two 436387- ---- A tool or a device to assist the transmission of twist tools. There are many different points on the bolt head, but they often have to be screwed in. The case where the shaft is the same as the bolt shaft α Screwing in or out of the bolt is a rather difficult point. Under the difficult and difficult conditions, the promotion of the force transmission is changed to the first characteristic step of the scope of the patent application. Please refer to this description. And the bolt of the target that transmits the torque. Its socket is connected to the wire in each case to another South Korea (the vehicle where the tool is wound). However, due to the return of the axis of its rotating element to become aligned, the connection: t: Mingzhi-further development, the socket has a cavity, with a polygonal cross-section along its longitudinal part, and The rotating element has a polygonal cross section to fit. The way in which these two mating parts are composed is one of some possibilities to ensure that the two areas are interlocked in a non-rotating manner in the direction of rotation.

436387 V. Description of the invention (2) According to the present invention, the side wall of the cavity of the specially designed socket is flat in a polygonal region, and thus it is easy to manufacture. According to a further development of the present invention, the rotating element in the polygonal region has a convex longitudinal section. When rotating the rotating element, it is attached to the side wall of the socket to cooperate with the convex outer wall to roll or slide. It is naturally possible that the side wall of the socket has the same shape, so the two spherical surfaces slide on each other. Keeping the rotating element in the socket, that is, fixing the rotating element to avoid being pulled out, can be achieved by a corresponding socket shape. However, if the manufacturing and positioning of the restoration element can not only straighten the rotary element, but also force it into the socket, the joint manufacturing can be particularly simple. Under this condition, the restoration element can perform the first function. Since it is under a force, it can also be designed so that the rotating element can be removed from the socket. -If the invention is further developed, the restoration element is a separate component, which is fixed in one of two places, especially on the socket and can be moved relatively. 9 In this way, K-, Α Γ is restored. Pieces are particularly helpful for matching the shape and

It? Λ As the present invention advances-at each step, the rotary joint contacts the bottom of the socket or the cavity to check or contact the fixing bolt before the magnet can be opened. The development, at least one set 'is introduced into the socket. The use of magnetic drive tools is well known. It is installed in the device and connected to the iron with a neutral position and ideally the end of the rotating element. It is screwed into the bottom of the rotating element and the socket to avoid being separated by an air. In order to maintain the rotating element in all further development The contact with the socket, such as the end of the rotating element that is introduced into the socket has a convex knot.

Page 5 4 3 6 3 8 ----- V. Description of the invention (3) The structure has a curvature of half, for example, a rotating structure formed by the restoration element about a radial direction. After removing or as in the present invention, the joint has at least a special The invention can be evenly divided and constituted 'it may be called a fox or a treasure, but it is particularly suitable if it is in the hole of the recovery element. As in the present invention, it is appropriate to enable the connection to straighten the rotating element. The diameter-matching rotating element can be actuated axially between the rotating bearings to apply a force. If the joint is provided with two around it, the restoration element can be straight or western, and its curvature is rounded. When the rotating element is actuated on the element, the recovery of a single distribution side is large. On the concave surface, the bead is formed. Rotate and rotate the element ‘between the vantage point. The position-recovery element is an actuating element, which is connected to the tangent curve and is lowered to the end of the center piece. Since the free end of the joint is not excessive, the part is suitable for the rotating element, and it has a special direction to the lug case. The rotating element is fixed to one with less use. However, if it is restored and the tight structure of the convex surface is changed. of. But if it is on the list, it is profitable. In the lugs, you can also go up. About one step along the radial direction is the development of 'the rotating element has a concave recovery element with a circular ring shape'. According to the present invention, for example, the recovery element can be operated under the action of the control elastic. Of course there are other possibilities too, especially with machine tools. Such as the spring action can be generated by a 0-ring. This is an economical and easy to replace component. For example, the O-ring can be inserted into the circular groove under the effect of tension and is restricted by the function of the restoration element. The use of two springs is to actuate on the recovery element and

Page 6 43 63 8 7

5. Description of the invention (4) Install 0-ring. According to the present invention, a groove can be made so that the 0-ring is connected to the groove horizontally. This also makes it possible to influence it from the outside. The additional pressure thus compressed by the spring, for example, is to act on the rotating element in order to compress the restoring element. The device used in mechanical tools is also suitable for compressing the O-ring from the outside, which can be used to make a sleeve that is replaced on the joint part of the socket. This sleeve can be moved to slightly compress the O-ring. The O-rings that are compressed at the same time can then be used to secure the sleeve so that they cannot be inadvertently moveda. As a further development of the invention, the restoring element is made of a compressible material 'or a compressible material component thereof. · If the present invention is further developed, especially if the restoration element is made of a compressible material, it can be positioned radially inside the socket and between the rotating elements. If the restoring element is made of a ring of elastic material which can be subjected to compressive stress, the special advantage ', as in the present invention, will produce such an effect. It is not necessary to have a complete ring structure 'and if it contains individual parts arranged along a ring, it will be sufficient. The joint proposed by the present invention may be part of a hand tool, for example, it can be directly fitted on a bolt driver. But the joint can also be part of a mechanical bolt driver assembly. The present invention proposes that the joint is-individual components are also possible, such as connecting it to a driving tool with a standard device, and the other end can be connected to a pliers.

43638 7 V. Description of Invention (5) Mouth. The present invention also proposes to combine several joints into one component, which allows a larger rotation angle. Further features, details and advantages of the present invention can be learned from the following description of a preferred entity and the accompanying drawings, which show: Figure 1: A section through a joint proposed by the present invention. Figure 2: A cross section roughly along the π-I I line in Figure 1. Figure 3: The entity of the present invention. In each case, some elements are combined with a rotary joint to form an assembly. Figure 4: The present invention proposes a joint as an intermediate component between a driving tool and a transmission mechanism. FIG. 5 is a description relative to another entity of FIG. 1. Figure 6: A section through the tool of Figure 5 along the VI-VI line. Figure 7: Connection elements as a device component. Figure 8: Another tool element that can be used with the present invention. Fig. 9 ... a side view of another joint element according to the present invention. Fig. 1 shows, as a first entity of the present invention, a cross section formed as a bolt driver having a front end portion of a joint. The first part of the joint forms a socket 1, which in the described entity has an opening facing the end face 3 of the module and inwardly it is an empty space 2 surrounded by a flat bottom 4. The portion adjacent to the end surface 3 of the cavity 2 is polygonal, such as an octagonal section having a planar inner side wall 5 (a region having a prismatic section and a region 6 having a circular section). The area 6 with a circular cross section shows 3 radial guide holes 7, which are slightly compressed 8 on the radially inner end. A bead-shaped restoration element 9 is inserted into each

Page 8 ^ 36387 V. Description of the invention (6) Inside a guide hole 7. The 10-end end of the rotating element is inserted into the socket 1 ', and it also has a polygonal cross-sectional structure in the area of the corresponding planar side wall 5. In the longitudinal section of the side view of Fig. 1, the outer wall Π is arched. Thus, a joint ′ that does not rotate in the direction of rotation is formed so that rotation of the arcuate outer side wall U of the rotating element 10 on the plane socket side wall 5 becomes possible. The area of the rotary joint 10 forming the rotary bearing is connected to a notch-shaped base 12. The reduced half-control position is connected to a four-shoulder 13 ′ in the shape of a cross section, and a ring 14 with a maximum radius is formed behind the shoulder. Leading socket} The spherical convex surface 15 of the internal rotating element 10 in contact with the flat bottom 4 of the cavity 2 of the socket 1 forms the end point of the element. -The radius-increased section 16 is connected to a rotating bearing outside the component forming the socket 1. The rotating element 10 is formed by a square neck 7 to facilitate insertion of a tool into an extension. FIG. 2 is a cross section of the joint passing through FIG. 1 and being horizontal with the radial guide hole 7. A ball 9 having a diameter approximately equal to the diameter of the guide hole 7 is inserted into each guide hole 7. Referring to the guide holes 7 mentioned in FIG. 1, through the compression 8 of the guide holes, it can be ensured that the ball 9 cannot enter the socket when the rotating element is not inserted. ^ On the outside of the component with the socket 1, the hole 7 enters an insert. A ring-shaped groove with an o-ring 丨 8 is shown in FIG. 1. The 〇-ring forces all the balls 9 to face radially inward, so that all the same forces can be applied to the bottom of the rotating element 〖〇 丨 2 the bottom ◦ = This force acts on all the balls 9 evenly, this rotation The axis of the element 10, centered and oriented, is aligned with the axis of the square socket 17. Because of the size of the 03 soil, it is the case where there is tension in the groove.

4363 8 7 V. Description of the invention (?) 21 Referring again to FIG. 1, the cylinder 20 with the component of the socket 1 can be sleeved on a sleeve. The left half of Fig. 1 shows one position, and the right half of Fig. 1 shows one alternative position. The sleeve 21 is partially sleeved on the cylinder 20 of the module. In other parts, the inner diameter is enlarged, but it is still smaller than the outer diameter of the cymbal ring 18 when it is not deformed. The inner edge 22 is slightly inclined up to the sleeve 21. If the sleeve 21 is moved from its inactive position to the left of FIG. 1 and fixed by a spring washer 23, the inner edge 22 of the front of the sleeve 21 is opened. , So Xu Tao indule 9. This position is shown on the right side of Fig. 2, where the spring washer 23 is forcibly held in an inner groove 24. The sleeve 21 is also set at this position with the operation produced by the O-ring 18. Since the displacement of the sleeve 21 is increased by the force, the recovery element, that is, the ball 9 ', straightens the rotation element 10. If the joint produces ft in a very fast rotating mechanical tool, in order to balance the rotation at the midpoint ^ centrifugal force for the ball 9 'This increased force is particularly advantageous: the solid body t tube 2 0 is based on- The replacement method is installed on the tool and the inner side is added and the O-ring is coaxially passed through the longitudinal axis of the tool. The inner side wall is in the amount. It is possible to shift the direction of movement to increase the pre-compression force of the O-ring due to the increase in displacement. It is also suggested in the present invention that it is possible for the turning element 10 to set the C guide to straighten. In this case, the sleeve 21 is not more precise and is suitable to be fixed to the tool with the help of a screw, so that it is also possible to fix the position of the sleeve with a locking nut. Feasibility ΐ 疋 改变 In the case of first-hand tools, changing the restoration torque is also true. If applicable to the case of a head, it is-larger or smaller

Face I

436387 _ Case number 89107874 V. Description of the invention (8) Provides a large restoration torque. Naturally, changing the shape of the rotating element can also change the restoring torque, such as the larger diameter portion 12 by the ball 9 acting on it. It can also be understood from FIG. 1 that the ball 9 is also connected to the supply shoulder 13 between the part 12 and the ring 14. Therefore, a force is also generated in the pumping direction, and the rotary element is pushed into the socket 1. This prevents the rotating element 10 from falling out of the socket 1. As shown in the left side of Fig. 1, since the bead 9 can be moved outward t toward the 0-ring, the rotating element 10 can be pulled apart by sliding upward through a sleeve 21. Figure 3 shows the possibility of combining several joints into a component according to the invention, which component can be inserted into a drive wire or string between a tool and a work piece. The component of Fig. 3 is controlled by one of the hexagonal base plates 30 at one end, which is fixed in the socket 31 and is detachable. A sleeve-like element 32 is provided at the other end, which includes a hexagonal inner opening in the shape of a bottom plate 30 for inserting the element. In each case, several joints are provided between the two parts so that the possible rotation angle of each other joint is gradually accumulated. Figure 4 shows another possibility of using a joint designed by the present invention. A square neck 3 4 is constructed on the left-hand end, and a bead 35 is inserted on one side of the neck under the action of a spring. The square neck is connected to the first socket 36, and it covers a swivel joint according to FIG. The rotating element protrudes from the end surface 37 of the socket 36, and is connected to the second socket 36, wherein the rotating element is inserted into the socket. A square opening passes from the end face of the socket 36 farther from the square neck 34 into the socket 36, and its shape and size are the same as those of the square neck 34. This component is shown in Fig. 41. It can be inserted between a driving tool and a nut, so that the rotating element 10 can be used as one of the two sockets.

O: \ 63 \ 63969.rtc Page 11 2001.02.12.011 436387 V. Description of the invention (9) Figure 5 is a longitudinal section similar to the front end of the tool shown in Figure 1. This tool also includes a socket 1 having a similar construction to the socket of the entity of Figs. The socket contains a cavity 2 which terminates inwardly on a flat bottom 4. From the bottom 4 outward, it is first connected to a region with a circular cross section, so the inner wall 6 of the cavity 2 forms the side wall of a circular cylinder. This side wall is also slightly biased. The cavity 2 with a circular section is connected to the section with a polygonal section, and its side wall 5 is manufactured in a horizontal plane manner, as shown in Fig. I, so it will not be described again. The rotatable element inserted into the socket is exactly the same structure as shown in Figure 丨, so it will not be repeated. A 0-shaped ring 4 of a compressible elastic material is inserted between the groove-like component 2 of the rotating element 10 and the inner side wall 6 of the cavity 2. Through the transmission between the polygonal section and the circular section, at least some points forming the cavity 2 protrude 41 inwardly, so that the o-ring 40 can be prevented from falling off. When the work piece has not been inserted, the o-ring 40 can be inserted into the socket in some way to give it some outward tension. 〇Open y ring 4 0 has been slightly compressed between the rotating element near the cavity side wall 6 and the groove 12 in the starting position. Drop it to straighten it. Based on the cavity 2's rotational symmetry and the rotation element inserted into the socket i & the element was straightened by the o-ring 40. The cross-section through the circle 5 tool is shown in Fig. 6, which shows that the o-ring 40 is used as a restoration element to connect all the sides of the inner side wall 6 of the cavity 2, and the o-ring 40 is used as the ring 2 and the ring 4. Case 'has the same thickness from beginning to end. Therefore, when Tian inserts the rotation element 10 ', the coaxial inner portion 4 2 of the rotation element 12 is formed.

Page 12 V. Description of the invention (10) The tools shown in Figs. 5 and 6 are assembled in the following manner. First, the o-ring 40 slides into the socket ', and then the rotating element 10 can slide axially. The ring 1 4 compresses the O-ring 4 0 until the tool reaches the bottom 4 of the cavity 2. The O-ring 40 then sits between the rotating part and the inner side wall 6 of the cavity. Based on the physical order described here, the restoring element connects β between the part of the rotating element that generates the rotation and the free end of the rotating element. Therefore, the fulcrum is very close to the end of the tool represented by end face 3. Reverse construction is also possible, but it is not recommended by the present invention. The possibility of changing the restoring torque in relation to the entity of Figure 1 can be achieved here using another O-ring, or with a different elastic coefficient, or with a different section. It is also possible to fit the O-ring to the site 2 in a forced compression manner, such as by vulcanization. -. Fig. 7 shows another possibility of manufacturing a rotary element 10 ', which can form part of a rotary joint or hinge as in the present invention. The rotating element 10 of FIG. 7 includes two joint parts which are made in a consistent manner and interlocked with a short part 16. This makes it possible to install the rotating element, for example, at the front end of a bolt driver, as shown in Figure 1 or 5, and then install a more extended component, as shown in Figure 8 = face: it contains a The socket 1 is a tool as shown in FIG. 5 and FIG. 6 and has a square-shaped driving part 34 on the other side. As shown in FIG. 8, the rotating element 10 of FIG. 7 is fixed to a hand tool or a mechanical tool, which increases a possible rotation angle. Figure 9 shows another ^ ^ piece, which is completely or firmly connected with a rotating part with a rotating element at one end, and the other end is fixed with a square terminal: 34. The square end is approximately the same as the element shown in FIG.

4363 8 7 V. Description of the invention (11) It can be fixed or can be inserted and removed in the groove. It is obviously also possible to use a combination of these elements, such as a swivel joint, which has a socket i at each end, that is, essentially another element corresponding to the element of FIG. 7. It is also possible to have a connecting element, but with a socket 1 masked at one end and a rotating part with a rotating element at the other end.
