In detail, it refers to a wire drawing mechanism of the racquet stringing machine. This creation can make the wire drawing mechanism have better load strength. . [Prior Art] i The racquet stringing machine is used to thread the racquet. A wire drawing mechanism is attached to one end of the racquet stringing machine to tighten the racquet string worn on the frame to the appropriate number of pounds. . The wire drawing mechanism of the 'I-age I know the racquet stringing machine, as shown in the new patent case of the "Rolling rod of the racket stringing machine" of the Chinese Patent Gazette No. 552986 (Application No. 091220970). The prior patent has a rod seat (1) and a line seat (2) pivotally connected by a shaft (27), one end of the line seat is provided with a wire gripper (3), and the other end face is provided. A recessed shaft chamber (21) is inserted through the ratchet column (12) of the rod seat (1). In addition, the wire base (2) is provided with a four-axis seat (23) at equal intervals around the shaft chamber (21), and a receiving groove (25) is disposed on each side of the shaft seat (23). The four blocking piece (24) is installed in the four-axis seat (23) and angularly displaceable, and each of the blocking pieces (24) is abutted by a spring (26) (each spring (26) is placed on the line The seat is seated in the groove (25) 'in the middle), so that the ratchet (242) of the flap (24) is spliced with the ratchet column (12). Thereby, the wire holder (2) can only be unidirectionally rotated with respect to the lever seat (1). The function of the one-way rotation of the wire seat (2) is that when the wire rod seat (1) is pulled to pull the wire, the wire seat (2) rotates with the pole seat to tighten the racket line; when the wire is not pulled, the wire can be pulled. Rotate the wire holder (2) in the other direction to adjust the angular position of the wire holder (2). The study found that the previous patent disclosure has the following shortcomings to be improved: First, the structure is complex. The wire holder (2) of the previous case is provided with a plurality of shaft seats (23) and receiving grooves (25) on one end surface for mounting the blocking piece (24) and the spring (26). It can be seen that the structure of the wire base is quite complicated and difficult to manufacture. 5 M285375 · Second, the load strength is not good. This section has two factors: Firstly, because the shaft seat (23) and the receiving groove (25) have a concave configuration and a complicated shape structure, the internal structure of the wire base (2) is complicated and difficult to be processed by metal parts. In a feasible way, it is made by plastic injection molding (the structure is also not easy to open). Since the blocking piece (24) is supported by the blocking surface (231) of the shaft seat (23), once the wire seat (2) is made of a plastic material, the supporting strength of the blocking surface (231) is not good, and it is easy. Damaged, affecting the shouting and salivation strength of the baffle (24) and the ratchet column (12). Secondly, please refer to the fourth picture of the previous case. The stop piece (24) and the engagement position of the ratchet column (12) are close to the center of the whole structure. In other words, the meshing position is shorter than the force arm formed at the center of the structure. The resistance torque is relatively reduced, which makes the strength of the force compromised. At the same time, due to the force arm, the baffle and the ratchet column must withstand greater stress to counteract the force applied to the stem (1), thus reducing its service life. [New content] This book aims to solve the lack of the above, and its main purpose is to provide a cable pulling mechanism for the racquet stringing machine, which has a simple structure and is easy to manufacture. Another object of the creation is to provide a pull mechanism for the racket (10) machine that provides a higher load strength. [Embodiment] In order to enable your review committee to further understand the purpose, characteristics and efficacy of this creation, the following silkbook creations - better _, and with the schema, are arranged as follows: First lap A perspective view of a preferred embodiment of the present invention is created. The first perspective is an exploded perspective view of the first figure. The second drawing is a longitudinal sectional view of the first figure. The fourth line is a cross-sectional view of the 4th to 4th line of the third figure. 6 M285375 The fifth figure is a side elevational partial cross-sectional view of the present embodiment after the cover is removed. The sixth figure is similar to the fifth figure, showing the state after the lever is pulled. The seventh figure shows the state of the reel idling. First of all, please refer to the first and second figures. This is a drawing mechanism (ίο) provided by the present embodiment. The utility model comprises: a bracket (20), the bottom end of which is used for mounting the racket stringing. On the machine (not shown), the cable pulling mechanism (10) is located at one end of the machine. A mandrel (25) is mounted horizontally in a bearing (23) of a pivot hole (22) at the top end of the bracket (20). . A rod seat (30) is threaded through the through hole (32) on the mandrel (25) and on the side of the bracket (20) to be rotatable. The lever (30) is rotated within a specific angular range (e.g., 150 degrees). This is a prior art and is not described. A pull rod (35) is inserted into the peripheral surface of the rod seat (30) for the user to drive the rod base (30) to rotate. - Adjusting weight (36), attaching the lever (35), and adjusting its position on the lever. When the weight adjustment block (36) is adjusted to different positions, the pulling force of the tie rod can be changed by the action of gravity drop to adjust the number of pounds of the racquet line. At least two jaws (40) are of the same configuration. Each of the claws (4 turns) has an arcuate body with at least one ratchet (42) on its outer peripheral surface and a recess (43) at each of the ends. The two claws (40) are respectively pivotally disposed on the outer side of the shaft (3〇) by the pivot hole (46) of the body, and the pivoting portion thereof can be rotated as a pivot point. . After pivoting, the two jaws are properly spaced around the mandrel (25), as in the fourth figure, and the head and tail ends are corresponding. That is, the head end (a) of one paw corresponds to the trailing end (b) of the other paw. The elastic members (45), which are equal to the pawl (40), are disposed at appropriate positions and are respectively elastically pushed against the two jaws (for example, one end of the spring is fixed to the rod seat and the other end is held by the pawl). The end of the pawl (b) keeps swinging outward, while the inside of the head end (8) abuts against the circumference of the M285375 · mandrel (25). The elastic member of this embodiment is a compression spring (45), and the two ends of each spring (45) are respectively installed in the recesses (43) of the corresponding ends of the two jaws (40). This ingenious design allows the spring to be set by the claws, and on the other hand, it can elastically push the claws, which can simplify the structure, facilitate assembly and effectively utilize the space. The '^ reel (50)' is threaded on the mandrel (25) with its fish-eye shaped plume (52), which is located on the outer side of the rod seat (30) and is rotatable. The fisheye pivot hole (52) of the reel is held by a C-shaped buckle (51) that is fastened to the mandrel so that the reel does not come out of the mandrel. Referring to the third figure, the inner side of the reel (50) is recessed with a circular chamber (54), and the circumference of the chamber (54) is provided with a continuous ratchet (56), such as Four pictures. When the reel (50) is pivoted on the mandrel (25), please refer to the third figure. The two claws (4〇) are accommodated in the chamber (54) of the reel, and the two claws (40) The ratchet (42) is engaged with the ratchet (56) of the reel (50), as in the fourth figure, whereby the reel (50) is unidirectionally rotated relative to the stem (30) . It should be noted that, in practice, the chamber (54) provided with the ratchet (56) and the two jaws (40) are interchangeably mounted, that is, the chamber (54) can be placed on the rod The outer side of the seat (3〇); and the two claws (40) are pivoted on the inner side of the reel (5〇), so that the engagement state of the fourth figure and the one-way rotation of the reel can also be achieved. The role. • A lateral slide (57) is provided on the outer side of the reel (50). The slide (57) is a circular projection (58) protruding from the outer side of the reel. And through to the circumference of the reel. Referring to the fifth figure, the slide (57) has a diagonal section (571) and a straight section (572) having a larger inner diameter in the embodiment, and the oblique section (571) is a large diameter thereof. The end is connected to the straight line segment (572). The two sides (571) (572) have a shoulder surface (573) and a second line clamp (60), which are in a symmetrical configuration, and are mounted in parallel parallel to the slide of the wire wheel (50). (57) can be displaced along the slide. The inner side of each clip (6〇) is a clip surface (62), and the inner end of the clip is provided with a tapered portion (63) with a width increasing toward the outer end. The clip is 8 M285375 * (60) (62) There are two pin holes (64) and two recess holes (65). The two pins (66) are respectively inserted into the pin holes (64) of the two-wire clamp (60), as shown in the fifth figure, so that the two-wire clamp can be synchronously moved in the slide rail (57). In addition, the two pins (66) do not closely match the pin holes (64), so that the two wire clamps can be allowed to change the gap therebetween. Two small springs (68) are respectively inserted into the recessed holes (65) of the two-wire clamp. When the two-wire clamp (6〇) is mounted on the slide (57), the tapered portion (63) is flatly attached to the oblique section (571), and the outer end of the clamp protrudes out of the slide. The elastic force of the two small springs (68) keeps the two-wire clamp (6〇) in an outward tension, and at the same time, the external tension acts to keep the outer end of the clamp (60) out of the slide (57), and the twist line The #6 (63) of the clip (6〇) is positioned against the shoulder surface (573) of the slide (5). In addition, a groove (69) is provided at the outer end of the clip for the racquet line to straddle the outer end of the clip. This creation can also be used to fix two semi-circular upper lower cover (70) on the outer end surface of the reel (5〇). Please refer to the first figure. After the two covers (7〇) are installed, the cover is The gap remains on the inside so that the racquet line can still be moved into the slide (57), and the cover prevents the clip (6〇) from falling out of the slide. This creation is as shown in the first figure. In the normal state, the two jaws (4〇) are like the ratchets (56) of the reel (5〇) as shown in the fourth figure, so the needle is pulled in the direction of the arrow (35). When the rod seat (30) and the wire wheel (50) are synchronously rotated. When this creation is used, 'first put the racket line on the racket, then pull the racket line to the pull mechanism (10)' as shown in the fifth figure, and wrap it around the reel (50) (the projection) (58)) The outer surface of the circumferential surface and the clamp (6〇) is then moved into the gap between the slide (57) and the second clamp (6〇). Then, the operator pulls the lever (35) in the direction of the fourth circle, so that the lever seat (3〇) and the edge wheel (50) can be rotated to the position of the sixth figure. In this state, the racket string is tightened. The outer end of the clamp (60) is pushed by the racquet line and moves into the slide (9). The two clamps are guided by the oblique section (571) to narrow the gap between the lines and the clamping surface (4) 9 M285375 · Clamp the racket line so that the racket line can be pulled to the appropriate number of pounds. After the racket line is tightened, the racket line is clamped at the frame, and then the lever (30) and the reel (5〇) are reversed (in the counterclockwise direction of the sixth figure), and the racket line is no longer pushed. The clamp (60), the clamp is the elastic outer tension, and the state of the fifth figure is restored, and the racket line can be removed. Referring to the seventh figure, when the rod (30) is kept moving, when the reel (50) is rotated clockwise, the ratchet (42) of the pawl (40) will slip over the spine of the reel. The tooth (56) displaces the tail end (b) of the claw to the inner corner. Thus, the reel (5〇) can be idling to adjust the angular position of the reel, so that the racquet line can be easily inserted into the slide (57). )in. In addition, this creation has a handle (59) on the outer circumference of the reel (50), which is convenient for the user to rotate the reel (50). The drawing mechanism provided by the present invention has the following effects: 1. The creation system is provided with a chamber on one side of the wire wheel (or the pole seat) for the jaws to be accommodated therein. The configuration of the chamber is simple and easy to manufacture, which can effectively save processing time or reduce the difficulty of mold opening. Furthermore, the creation of the spring is ingeniously mounted between the jaws, which also effectively simplifies the overall structure and simplifies the structure. Second, the wire drawing mechanism of this creation can withstand a large load: Please refer to the fourth figure, in the driving state of the wire wheel and the rod seat, the inner side of the claw end (a) is abutted against the mandrel (25) ) Weekly. In other words, the force of the paw is received by the mandrel (25). Since the mandrel is made of metal, it has better support strength and is not easily damaged. In the second case, the ratchet of the claw and the ratchet of the reel (or the rod) are located close to the outer circumference of the reel, that is, the position of the recumbent position has a relatively long force arm from the center of the mandrel (25) due to When the force arm is long, the resistance torque is relatively increased. Therefore, when the pull rod is pulled by a certain force (the rod seat and the wire wheel are rotated), the stress of the M285375 of the pawl and the ratchet of the reel is relatively reduced, which can be avoided. In the case of damage, the strength of the cable pulling mechanism can be increased and the service life is long. In summary, this creation is the first of its kind in the same category, with practical improvements, and applications are made according to law.
