INSTRUCTIONS OF THE INVENTION: TECHNICAL FIELD OF THE INVENTION The present invention relates to a bicycle accessory, and in particular to a chain breaker having a reinforced structure for repairing a chain.疋3 kinds of [previous technology] - The bicycle with the variable speed function is made by using the toggle button to match the chain of different circular diameters, so as to achieve the long-term use in the long-term or the shifting operation. Improper, it is easy to cause two and the chain plate to deform, or even damage 'and when the chain plate is deformed, the shifting operation is not smooth' is also easy to make the chain disengage. It will be higher in level. Therefore, for racers or amateur riders, it is necessary to repair the chain immediately when the chain of the t-chain is broken or bad. The bicycle will be equipped with a chain breaker. The utility model comprises a chain base 1 and a single area connected to the swaying member 2. As shown in FIG. 1 , a conventional chain shackle, a screw, and a swaying piece 2, 3 and a inside the chain splicing seat 1 are provided. The grips 4 and 襄 arranged on the adapter 3 are provided with: the positioning portion 1 〇 1 L of the set position has a screw for the ejector 2, and a recess is provided on the side of the positioning portion 101 The recessed empty card is formed and protruded in the recessed space 102 and the pin for positioning the chain spans two/3. When the chain is positioned across the locking portion 103 and the key strip is applied to the tilting member 2, the screwing of the tilting member 2 is performed, and the key panel* and the key panel can be disengaged. 'Or the pin is placed on the chain 1 of the chain to reach the repair chain entry. Although the sander and the shackle W have the function of repairing the chain, when the 掣5 1255211 is engaged in the boring operation, the positioning joint will bear a larger gentleman/, and the carding part 1〇 3 The stress of the drought and the big one, so in design, the thickness of the bottom of the chain seat 1 is strong to strengthen the structure, and also: the increase of the chain can not achieve the purpose of reduction. Also, the present invention is directed to a chain splicer having a reinforced structure which provides a unitary structure. And the shackle having the reinforced structure of the reinforced strip can be pushed by the fa1 of the operation-chain link plate, and the shackle is pivoted on the seat body =: The body has a first end, a second end that is opposite to the first end, a δ and a set opposite to the vine, and the opposite: a fixed-bottom eight n 'concave work chamber extending from an axis and a card portion protruding from the concave surface of the recessed space, the positioning portion having a hole along the hole, the card portion being for the key bar : the screw hole of the extended screw body has two; the member is screwed at the opposite end of the tilting end of the ^ " 4 and the rear end of the king Make the end.

" and Figure 3, the chain shackle of the present invention having a reinforced structure is more For example, one of the pin bars 210 for operating a button fan is pushed between the two sets of key plates 220. The chain breaker 100 includes a body 10, a member that is screwed inside the seat body 1G, and a cover plate 30 pivotally mounted on the seat 胄1〇. The base body 1 is formed into a rectangular block shape, and has a first end portion u, a second end portion 12 opposite to the first end portion J ig 6 Μ > a positioning portion 13 extending along one end portion 11 and extending along the axis L, a pivoting plate portion 14 corresponding to the second end portion 12 and disposed opposite to the positioning portion 13, and a plate portion p 14 and the positioning portion A recessed space 15 between the 13 and a latching portion 16 projecting from a bottom surface of the recessed space 15. The positioning portion 13 has a U (four) L extending screw hole 131 and two slots 132 recessed at the top edges of the top. § 槐 槐 # 14 has a pair of through holes (4) that should be axis l. The card portion 16 is positioned for spanning the chain and has two latches 161 that are releasably positioned on either side of the pin 210 to be pushed. The sigma push 4 member 20 has a main rod 21 extending along the axis L and an operating rod 22 coupled to the main rod 21 in a zigzag shape. The main rod 21 is screwed into the screw hole 131 of the side seat body 10, and has a pair of swinging end portions 211 of the portion to be engaged and an operating end opposite to the tilting end portion 211: 212 The operating end 212 has a perforation 213 perpendicular to the axis L. The operating lever 22 is detachably inserted in the through hole 2丨3. The cover plate 30 is formed in a hollow frame shape and has a pivotal end portion 3 1 , _ 〇 〇 枢 枢 枢 枢 枢 枢 枢 枢 枢 枢 枢 枢 7 7 7 7 7 7 7 7 7 7 7 7 7 7 的 7 的Instigating knowledge. The cymbals 32 and 2 extend from the pivot end 31 to the straddle 33 of the oscillating end 32. When the oscillating end portion 32 is brought into a closed position on the positioning portion 13, the straddle rods 33 are sleeved in the card slots 132. As shown in FIG. 4, the imaginary line and FIG. 5, when the chain 200 is to be repaired, i is first opened, and the oscillating end portion 32 is operated to be an open position from the heart portion 13. 'And the key strip 2 (10) section to be repaired " sets. The recessed work room 15 towel, and the card block (6) can smoothly position the key bar _ at this time, the pin 21 〇 corresponds to the axis l And the swinging end 32 of the child board 30 can be pivoted back to the closed position from the open position. As shown in FIG. 6, the operating rod a of the tilting member 2Q can be driven and the main rod 21 can be screwed along the axis L. The tilting end portion 211 can be added from the rod. The chain plate is launched in detail. Then, the main rod 累 is retracted to the original position, and after the operation is repeated, the damaged chain & 22 〇 can be removed, and the undamaged chain plate 22 () can be set in the card portion. On, the pusher 2. The pin 21 is urged to penetrate the chain plate η. The connection is for repair purposes. Hereinafter, the advantages of the present invention will be further described as follows: 1. The cover plate 30 is straddled on the top of the positioning portion of the seat body 1 :: plus; T device 1 〇. The structural strength, that is, the cover 3 is utilized. No: When the 2° operation is performed, the average stress is assumed, and the base is increased in thickness to have sufficient structural strength. 8 1255211 Second, the setting of the cover 3G is provided in the operator's basin - when the hand is held (4) on the seat 1G, the thumb can be positioned against the cover 3〇 Conducive to the smooth operation of the other hand. However, the above description is only for the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent change of the present invention is based on the information and the description of the invention. Repairs are still covered by the patents of the present invention.
