Technical characteristics.

Generally speaking, the tools used in disassembling and assembling the bicycle are nothing more than a spanner wrench, a cross or a word screwdriver, and these tools are housed in the tool box, allowing the user to repair, disassemble, and assemble the bicycle. The parts can be collected in a centralized manner, but in the above description, the storage of a plurality of tools causes the user to waste more energy on carrying, and the tools applied to the parts of the bicycle are not the same, so that the user must always be in the tool box. Finding the right tools not only wastes working hours, but also makes it easier to lose and drop the tools. Therefore, the creator further concentrates the components with disassembly functions on the handle body (1), so that the user can carry The single handle body (1) can disassemble and assemble the relevant parts on the bicycle, and the handle body (1) is further differentiated to have a head before the components of the handle body (1) can be disassembled and assembled. (11), a body (12) and a tip (13), the head (11) is inclined Y-shaped design, The top end of the head portion (11) is recessed in the direction of the handle body (12) with a tooth-removing arc groove (3), and the groove wall surface of the unloading arc groove (3) is provided with a plurality of teeth convexly arranged side by side and spaced apart (31), and the outer crank cylinder (40) of the five-way pipe is disassembled by the arrangement of the teeth (31), as shown in the sixth figure, and the unloading arc groove (3) can also be removed. For the upper sprocket screw (50), please refer to the seventh diagram. In addition, the disassembly components provided at each part of the shank (1) are explained in the next section.

For example, the unloading arc groove (3) provided at the top end of the head portion (11) is used to disassemble and assemble the five-way pipe of the bicycle, the crank nut (40) or the disk screw (50) of the disk, The ratchet ring (21) disassembles the disc (20) and the toothed disc (30), and the rod (22) is used for positioning and disassembling a specific screw (10), and the handle body (1) has a plurality of unloading functions. The components are designed to greatly shorten the time for construction and avoid the problems of loss, falling and damage when replacing tools, and provide users with convenience and lightness in carrying. Please refer to the sixth figure and the first The seven figures are shown.

In addition, there are many repairs, disassembly and assembly on the bicycle. In addition to the above three components of the unloading function, other dismounting functions are further explained below: First, the bicycle ride for a long time will be because The lateral force and external impact, which are subjected to impact, cause wear and deformation, especially on the disc (20), so on the side of the head (11) of the present invention, and between the unloading arc At least one of the slots (4) is disposed between the slot (3) and the first driving member (2) (in the present drawing, the two trigger slots (4) are used as an embodiment), and the user can at least one of the triggers The slot (4) is inserted into the deformation of the disk (20), and then the user swings the handle body (12) of the handle body (1) to swing in the opposite direction of the deformation of the disk (20), through the at least one wrench The clamping of the groove (4) restores the deformation portion, and the two clamping grooves (4) of the drawing have different depths according to the different sizes of the disks (20), and the user can follow the disk ( 20) The size or the amount of deformation at the deformation to select the most suitable trigger slot (4) Use, so that the user can ride smoothly, please refer to the fifth figure.

Secondly, one of the more important aspects of the bicycle is to provide a user-safe braking system, which mainly uses the brake wire to cooperate with the caliper (60) to clamp the brake block located in the caliper (60) against the disk ( 20), the wheel is changed from the rotating state to the stopped state (the brake system is a conventional technique, and will not be described again here), and one of the important components for providing the wheel brake is a piston located in the caliper (60). When the user performs the braking action for a long time, the piston is likely to be unable to be reset and the brake block is normally clamped to the disk (20). Therefore, the creation utilizes the design of the tipping portion (13), which is 11) is a non-orthogonal connection with the body portion (12), and the tip portion (13) is parallel to the head portion (11), and the tip portion (13) is connected to the handle portion (12) One end is gradually thinned toward the other end, so when the piston can not be reset after pushing against the brake block, the user can insert the gap between the caliper (60) and the disc (20) by using the cocking tip (13). And the left and right toggles enable the piston to be reset, and the brake block is released from the state of the disc (20), providing the user with the ability to After riding the brakes continue smoothly, please refer to the tenth shown in Fig.

Thirdly, there is an important point in the bicycle, which is a driving lubrication-pedal assembly between the user and the bicycle. The general pedal assembly includes two pedals, two cranks (70) and a pedal spindle (80). (The pedal assembly is a conventional technology, and will not be described here.) The user is most likely to cause deformation and wear of the pedal spindle (80) during a long ride, so it must be replaced and repaired regularly. A handle body (12) is formed on the handle body (12) of the handle body (1), and a second driving member (5) for disassembling, assembling the bicycle crank portion and the rear shifting related component is fixed to one end of the tip end portion (13). The second driving member (5) includes a hollow cylindrical tubular portion (51) and a gear tooth portion (52), and the annular tubular portion (51) is located at one side of the handle body portion (12), and the The gear tooth portion (52) is located on the other side of the handle body portion (12) and is integrally formed corresponding to the ring cylinder portion (51), and the ring cylinder portion (51) has an assembly groove and is located on the outer peripheral side. A plurality of rods (511) are arranged around the ring, each rod (511) is arranged side by side at intervals, and the ring portion (51) is a pedal spindle (80) for removing the crank portion of the bicycle. After the bicycle pedal and the crank arm are disassembled, one end of the ring portion (51) with the plurality of rods (511) is inserted into the pedal mandrel (80), so that each rod bar (511) is corresponding to the pedal mandrel (80). Rotating and dismantling allows the user to further change the pedal spindle (80), see Figure 8.

Following the above description, in the part of the gear tooth (52), when the user wants to remove the pedal spindle (80), the premise is that the pedal and the large crank (70) need to be detached from the bicycle first, and the large The crank (70) must be detached from the bicycle through the design of the gear portion (52), and the design of the gear portion (52) includes a disc body (521) and a snap block (522), the disc body (521) is in the form of a disk and has a circumferential surface surrounded by a serrated surface, one side of the disk body (521) is attached to the handle body (12) of the handle body (1), and the snap block (522) Then, the disk body (521) is attached to the opposite end of the handle body (12), and is integrally formed with the disk body (521). In addition, in the design of the snap block (522), in order to be able to disassemble the large crank ( 70), the outer ring side of the snap block (522) is further provided with a plurality of convex teeth (5221) and grooves (5222) which are arc-shaped, and the convex teeth (5221) and the grooves (5222) are Interleaved arrangement, that is, the outer circumferential side of the snap block (522) is sequentially arranged with convex teeth (5221), grooves (5222), convex teeth (5221), and grooves (5222). , generally large crank (70) and bicycle assembly will have fixed components will be large The handle (70) is fixedly mounted on the bicycle and does not affect the assembly of the pedal spindle (80). For this reason, the user has to remove the large crank (70) from the bicycle, and only the tooth portion (52) The snap block (522) is partially inserted into the position where the large crank (70) is connected to the bicycle, and then the swinging force is applied through the swing of the handle body (1), so that the fixing member of the large crank (70) set on the bicycle is disengaged. The large crank (70) can be removed from the bicycle in one step, as shown in Figure 9.

With a large number of disassembling bicycle tools assembled on the handle body (1), the user can carry out the assembly and disassembly of the bicycle parts by simply carrying a single handle body (1) for maintenance, thereby greatly reducing the conventional It is necessary to carry the weight of the tool box, which makes the user more convenient and easy to carry. In addition, in the disassembly of different parts of the bicycle, the user only needs to use the components on the handle body (1) according to the requirements of each part. It is not necessary to replace different tools in the tool box as in the past, but it causes problems such as loss or falling of the tool. In addition, the creation reduces the application by the concentration of each component. Time, in addition, can maintain the stability of the bicycle after assembly, the integrity of the parts removed. Compared with the prior art, the creation has more practical significance, and is simple, convenient, and easy to use in operation, and does not need to occupy too much space for carrying, which is the best for users who provide bicycle related fields. Operating tools.
