There is a top ring 71 that is adapted to abut one end of the resilient member 40. The first fixing member 80 is disposed in the slot 11 disposed at the rear end of the main bracket 10, and the first fixing member 80 is coupled to the second fixing member 90, and the other end of the elastic member 40 is abutted against the second fixing member 90. The second fixing member 90 has a tubular body 91 penetrating into the coil of the elastic member 40, and the tubular body 91 is inserted into the movable shaft 70. Preferably, the second fixing member 90 has a hemispherical type one of the screw heads 92, the screw head 92 is connected to the tubular body 91, and the screw head 92 is abutted against the other end of the elastic member 40, and the first fixing is performed. The member 80 has a groove portion 81, and the groove portion 81 provides a corresponding fitting of the screw head 92 of the second fixing member 90 for positioning the second fixing member 90, and the movable shaft 70 penetrates into the tube body 91. During the compression or relaxation of the resilient member 40, a stable travel space for the movable shaft 70 is provided, thereby ensuring that the resilient member 40 is not deflected.

In the above, the inner wall surface of the socket 11 of the main bracket 10 and the outer wall surface of the first fixing member 80 are provided with a thread, and the first fixing member 80 and the socket 11 are engaged through the thread, and the first fixing member 80 can be The thread is moved back and forth with respect to the slot 11 in an active manner, as shown in FIGS. 6 and 7. In detail, the upper and lower portions of the housing 11 have a through hole 111, and the first fixing member 80 is inserted into the housing 11 through the through hole 111, and the first fixing member 80 is connected to the through hole. The through hole of the hole 111 is the same as the slot 82. For example, the slot 82 can be a hexagonal hole or other shaped hole. The user can insert the hand tool into the through hole 111 below the slot 11 to engage the slot. 82. The first fixing member 80 is rotated by the hand tool, so that the first fixing member 80 can be moved relative to the housing 11 by the thread, thereby adjusting the tightness of the elastic member 40. It is worth mentioning that the position of the elastic member 40 and the manner of connecting the movable shaft 70, the first fixing member 80 and the second fixing member 90 allow the user to use the hand tool to rotate the first fixing member 80. The first fixing member 80 is disengaged from the socket 11 to facilitate maintenance or replacement of the elastic member 40.
