[0008] Preferably, the diameter of the top buckle rod does not exceed the diameter of the mounting hole, the length of the positioning surface is not less than the depth of the mounting hole, and the width of the positioning surface does not exceed the diameter of the top buckle rod.

[0009] Such a setting can ensure that the top button rod can be inserted into the mounting hole to achieve connection with the locking rod, and the positioning surface length is not less than the depth of the mounting hole, so that the installation position of the top button rod can be adjusted, so that the top button rod can assist in positioning buttons of different diameters on the button clamp.

[0010] Preferably, both the first fixing hole and the second fixing hole are threaded holes, and the number of the first fixing hole and the number of the second fixing hole are at least one each.

[0011] With such an arrangement, the locking rod and the top buckle rod can be fixed by utilizing the cooperation of the thread and the screw, and the multiple fixing holes can make the connection more secure.

[0012] Preferably, the other end of the top buckle rod is fixedly sleeved with a buffer sleeve, and the material of the buffer sleeve is rubber or silicone.

[0013] Such an arrangement can protect the button when the button rod contacts the button, preventing the button rod from causing scratches on the button surface and affecting product quality.

[0014] Preferably, the connecting hole completely passes through the locking rod.

[0015] With such arrangement, the installation position of the locking rod on the output shaft of the rotary cylinder can be adjusted to achieve positioning of buttons of different diameters on the button fixture.

[0016] The advantages and positive effects of the utility model are:

[0017] The utility model drives the locking rod to rotate by rotating the cylinder, so that the locking rod drives the top button rod to rotate, so as to position and fix the button on the button clamp; the installation position of the top button rod can be positioned by the positioning surface on the top button rod to avoid reverse installation; the length of the top button rod can be adjusted by the second threaded fixing hole and the fixing screw, so as to position buttons with different diameters; and the buffer sleeve installed on the top button rod can prevent the top button rod from directly contacting the button and causing damage to the button.
