The adjustment member 28 is movably connected to the frame 26 and includes a first threaded rod 42, a second threaded rod 44 located corresponding to the first threaded rod 42, and an adjustment portion 46 connected to the first and second threaded rods 42, 44. As shown in Fig. 3, the adjustment member 28 is movably connected to the frame 26 and the adjustment portion 46 is exposed between the two ribs 34 of the frame 26 so that the user can directly switch the adjustment portion 46 to rotate the adjustment member 28.
The first stop member 30 includes a first threaded hole 48 to which the first threaded rod 42 of the adjustment member 28 is threadedly connected. The first stop member 30 is substantially perpendicular to the first side 20 of the second slide member 12. The first stop member 30 further includes a first stop portion 50 which is located corresponding to the first side 20 of the second slide member 12.
Furthermore, the first stop portion 50 has a first protrusion 52. The first protrusion 52 has a first contact surface 54, a first guide surface 56 and a first top 58 which is located between the first contact surface 54 and the first guide surface 56. If the first protrusion 52 is a solid member (not shown), a resilient member is preferable, such as rubber. Alternatively, the first stop portion 50 has the first protrusion 52 and the first protrusion 52 has a hollow interior 60 which is shaped correspondingly to an outer contour of the first protrusion 52, so that the first protrusion 52 can be deformed in the hollow interior 60. The hollow structure allows the first protrusion 52 to be made by harder resilient material such as plastic, and the first protrusion 52 and the first stop member 30 can be a one-piece member.
The resilient material is not restricted the material mentioned above, other resilient material is included in the resilient material mentioned above.
