Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

See fig. 1, the utility model discloses a set up the casing 1 of inner chamber, 1 non-operating conditions of casing lie in the subsurface and upper surface and flush with ground, set up the pin device respectively, be used for releasing the button 3 of pin device in the inner chamber of casing 1, and be used for locking the locking means 6 of pin device in casing 1. The gear lever device comprises a gear lever 2 and a first spring 7, the gear lever 2 is located in a first inner cavity 101 of the shell 1, the bottom of the gear lever 2 is connected with one end of the first spring 7, and the other end of the first spring 7 is connected with the bottom of the first inner cavity 101. In the relaxed state of the first spring 7, the upper surface of the bar 2 is flush with the upper surface of the housing 1. The button 3 is sleeved in the cylindrical second inner cavity 102 of the shell 1 by a second spring 4. In the relaxed state of the second spring 4, the pressing surface of the button 3 is flush with the upper surface of the housing 1. The tail part of the locking device 6 is connected with one end of the third spring 5, the other end of the third spring 5 is connected with the third inner cavity 103, and the tail part of the locking device 6 is provided with an inclined guide surface 602. In the relaxed state of the third spring 5, the pointed projection 301 at the lower end of the push button 3 is located above the guide surface 602 of the locking device 6, and the projection 301 has an inclined surface with the same parallelism as the guide surface 602.
