The finger 50 includes a recess 52 for receiving the rib 46 when the second shell 2 is in the second position relative to the first shell 1. The second shell 2 can be moved from the second position relative to the first shell 1 as the rib 46 can be moved from the recess 52 due to elasticity of the finger 50. In the shown embodiment, the holder includes a second finger 54 so that the cap 44 is located between the fingers 50 and 54.
[0027] The mount M further includes a device for pushing the second shell 2 from the first position when it is released from the first retaining device. The pushing device may be a spring-biased type including a spring 56 secured to the first shell 1 and a block 58 secured to the free end of the spring 56. In the shown embodiment, there are two spring-and-block combinations and, instead of being attached to the first shell 1, they are attached to a metal plate 60 attached to the first shell 1. The metal plate 60 is used to enforce the first shell 1. Preferably, a stem 62 is secured to the metal plate 60. The spring 56 is mounted on the stem 62 inserted in a stem-receiving hole 64 defined in the block 58, thus ensuring smooth movement of the block 58. Although not shown, the pushing device may be an elastic plastic block or an enclosure filled with pressurized air. There is a block-stopping device for stopping disengagement of the block 58 from the stem 62. The block-stopping device includes a C-ring 66 received in an annular groove 68 defined in the stem 62.
[0028] The first shell 1 includes a top 70 and a periphery 72 projecting from the top 70. The periphery 72 includes an opening 74 which can be sealed by means of a door 76 linked to the periphery 72 in a pivotal manner. The door 76 includes two shafts 78 projecting in opposite directions therefrom. Two shaft-receiving holes 80 (only one of them is shown in FIG. 1) are defined in the periphery 72 on opposite sides of the opening 74. Each of the shafts 78 is received in a corresponding one of the shaft-receiving holes 80. A torque spring 82 is mounted on one of the shafts 78 and includes an end secured to the periphery 72 and an opposite end secured to the door 76. Thus, the opening 74 is closed by means of the door 76 when no external force is exerted on the door 76.
[0029] The second shell 2 includes two ears 84 (only one of them is shown in FIG. 1) formed on two opposite sides thereof for engagement with the blocks 58. In the shown embodiment, instead of being connected with the second shell 2, the second portion 38 of the hinge 34 is connected with a second metal plate 86 connected with the second shell 2. The second metal plate 86 is used to enforce the second shell 2. Particularly, the second portion 38 is connected with a tab 88 projecting from the second metal plate 86 in a right angle.
