In the present embodiment, it is disclosed that one side is provided with a lock bolt (70), and the opposite side of the lock hole (25) can be closed by an inner cover by a hole cover (26). Of course, if the lock bolt (7〇) is selectively installed on the other side, the hole cover (26) is removed and replaced with a lock hole on the corresponding side (2, so the lock bolt (70) and the The second spring (73) can be changed left and right as required and displaced in the same transverse chute (29). As shown in the ninth figure, the components of the present invention, including the handle (34), are The lower linkages (41), (42), the coupling body (5 toggle plate (60) and the lock cylinder (70), etc., can be adjusted to the left and right, so that they are exactly the lock bolts (70) shown in the sixth figure. It becomes the right side, and its function and operation are completely inconsistent. 5 ' In addition, another feature of this creation is that only the lock lever (44) or the lock bolt (70) can be selected according to the requirements. Referring to the tenth figure, it discloses the first feasible example of the present invention, which is substantially the same as the first embodiment, and only the upper and the ends of the lock lever (44) are removed, but only by the side. The lock bolt (7〇) acts as a control for opening the I lock door. # ' or the eleventh figure is the third feasible embodiment of the present creation, which differs from the first embodiment in that it is placed on the joint body (5〇) Dial up The plate (6〇) and its 2 locking bolts (70) are removed, and the hole is replaced by a hole cover (26). (2y closed this = -11 - M297995 This creation becomes a kind of upper and lower end The lock lever (44) acts as a control to open or lock the door. It is known from the above embodiment that the same lock case (2〇) can be used to select the use type of the lock according to the demand, and has a multi-purpose use. In summary, the structure revealed by this creation is unprecedented, and it can achieve the expected effect, and is available for industrial utilization, fully in line with the new patent requirements.
