It is assumed to be inserted freely. In the embodiment shown in FIGS. 6 to 10, the link 23 is provided with a coil spring 42 wound thereon, and the upper end of the coil spring 42 is pressed against a pressing portion 31 formed in the handle 3. The lower end of the coil spring 42 is engaged with the engaging portion 23 a formed on the link 23, and the coil panel 42 is inserted into the inner member 2 so as to be elastically movable up and down by the elastic force of the coil panel 42. It has been done. The engaging member 24 is made of a synthetic resin molded body or the like, and is provided with a projection 24 a at a lower portion. The projection 24 a is detachably engageable with the pinion 21 so that the pinion 21 is detachable. The rotation of 2 1 is freed or prevented. The grip handle 3 is made of a substantially U-shaped member made of synthetic resin or metal and made into two halves, and these members are joined by screws or the like to have an internal J space. . The grip handle 3 is straddled over the upper end of the inner member 2 by joining the substantially U-shaped ends of the grip handle 3 to both upper ends of the inner member 2 by screws or the like. . Further, in the space of the handle 3, there is provided an operation part 32 which projects from the inside to the outside and can be pushed in from the outside, and swing levers 3 are provided on both sides of the operation part 32, respectively. There are three. The swing lever 33 has a central portion pivotally supported inside the handle 3, one end of which is pivotally supported on both sides of the operation portion 32, and the other end of which is connected to the link 23.

Then, the link 23 is raised, and the engaging member 24 connected to the lower end of the link 23 is also raised. When the engagement member 24 is pulled up, as shown in FIGS. 4 and 9, the engagement between the projection 24 a provided at the lower portion of the engagement member 24 and the pinion 21 is released, and the pinion 2 is released. 1 rotation becomes free.

Then, when the user lifts the grip handle 3, while holding the grip handle 3 of the handle extension device, the pinion 21 rotates and rises while engaging with the rack 13, so that the pinion 2 The inner member 2 that pivotally supports 1 at the lower end can also gradually slide the outer member 1 so as to protrude upward from the outer member 1. As shown in Figs. Can be stretched to an appropriate length to make it the optimal size for the user. When the user stops pushing the operation unit 32 with the handle 4 in the optimum size for the user, the operation unit 32 is restored to its original state by the elasticity of the torsion spring 41 and the coil panel 42. Then, one end of the swing lever 33 supported on the operation unit 32 is raised, and the other end of the swing lever 33 supported on the link 23 is lowered. Then, the link 23 is pushed down, and the engaging member 24 connected to the lower end of the link 23 is also pushed down. When the engagement member 24 is pushed down, the projection 24 a provided at the lower portion of the engagement member 24 engages with the pinion 21, and the rotation of the pinion 21 is prevented.

Therefore, in this state, even if the user grips the handle 3 of the handle extender and raises the handle 3, the rotation of the pinion 21 is prevented, so that the pinion 21 is connected to the rack 13. When the handle 4 is kept in an optimal size for the user in a state where the handle 4 is kept fit, and the user is transported in this state, the handle 4 becomes easy to hold and transport.

Next, in a state where the handle 4 is set to the optimal size for the user, the user again grips the handle 3 of the handle intermediary device and pushes the operation unit 3 2 with the thumb to operate. One end of the swing lever 33 on the supporting side is lowered, and the other end of the swing lever 33 on the side supported by the link 23 is raised. Then, the link 23 is pulled up, and the engaging member 24 connected to the lower end of the link 23 is also pulled up. When the engagement member 24 is pulled up, the engagement between the pinion 21 and the projection 24 a provided at the lower portion of the engagement member 24 is released as described above, and the rotation of the pinion 21 is free. Become. '

Therefore, if the user holds down the handle 3 of the handle extender and presses down the handle 3, the pinion 21 rotates and descends while engaging with the rack 13. The inner member 2, which is pivotally supported at the lower end, can also slide the outer member 1 gradually into the outer member 1, and retract the handle 4 as shown in Figs. Can be in original short condition You.

Then, when the user stops pushing the operation unit 32 in the original short state in which the handle 4 is contracted, the operation unit 32 returns to the original state by the elasticity of the torsion spring 41 and the coil spring 42. One end of the swing lever 33 supported on the operation unit 32 is raised, and the other end of the swing lever 33 supported on the link 23 is lowered. Then, the link 23 is pushed down, and the engaging member 24 connected to the lower end of the link 23 is also pushed down. When the engagement member 24 is pushed down, as shown in FIGS. 2 and 7, the projection 24 a provided at the lower portion of the engagement member 24 and the pinion 21 engage, and the pinion 21 Rotation is blocked.

Therefore, in this state, even if the user grips the handle 3 of the handle extension device and pulls up the handle 3, the rotation of the pinion 21 is prevented, so that the pinion 21 is connected to the rack 13 by the rack 13. When the handle 4 is kept in the original short state in which the handle 4 has shrunk, and the ball is stored in this state, the handle 4 can be easily stored without disturbing. The invention's effect

Since the present invention is configured as described above, it is possible to adjust the dimensions of the handle in multiple steps at fine intervals. It can be easily transported, and has excellent effects such as making the device itself low in volume, and being able to be put on well when worn.
