The above-mentioned engagement state is as shown in the sixth figure b. ^ When the button 4 is pressed (9), its moving part (9 2) will move backward, and the driven part (7) of the engaging block (7) ( 7 3) It will squeeze back. With this, the snap block

Page 18 444094 V. Description of the invention (15) (7) will withdraw against the elastic force of the engaging spring (7 1). As a result, the front engaging portion (7 2) and the engaging portion (1 5) of the case (1) will be separated, and the handle (2) will be raised due to the action of the coil spring (4 4). The raised handle (2) can be pivoted to separate the engaging metal (20) from the engaging portion (not shown) of the door frame, and the box door can be opened. When the handle (2) is pivoted, the handle (2) must have an excellent gripping effect. Here, a storage portion (3 1) for accommodating a push button (9), an engaging block (7), and a lock (5) is formed at the front end of the handle (2) body, and the entire storage portion (3 1) can be As a part for holding the handle, the stable holding effect of the handle (2) can be enhanced. In addition, the front end surface of the storage portion (3 1) is open, and the front end surface of the pressing button (9) and the front engaging portion (7 2) are exposed at the front end of the storage portion (3 1), so that the overall length and grip of the handle The effect can be effectively improved. In this embodiment, the left and right sides of the accommodating portion (3 1) are covered with pressing buttons [9], so that the movable pressing button (9) protrudes from the accommodating portion (3 1), but its unstable state The holding conditions can be eliminated as a result. When the handle (2) is inverted, the handle (2) can also pivot downward against the elastic force of the spring (4 4). If this is done, the lower part of the front end of the engaging block (7 2) and the upper part of the engaging part (1 5) become a bevel structure. When the engaging block (7) resists the engaging spring ( When the elastic force of 7 1) is retracted, the front engaging portion (7 2) is still engaged with the engaging portion (1 5). At this time, if the push button (9) and the engaging block (7) are integrated into one

Page 19 V. Description of the invention (16) In the structure of the type (16), due to the action of the spring (4 4), the front engagement portion (7 2) and the engagement portion (1 5) can be released from the engagement state. Since the lean button (9) and the engaging block C 7) are different components in the handle of the present invention, the engagement between the front end engaging portion (7 2) and the engaging portion (1 5) The status will not be lifted. In more detail, the spring (4 4) applies a spring force to the entire handle (2), and the elastic body is composed of the front engaging portion (7 2) and the engaging portion (1 5 ).
