is made up of a button
31
, a spring
32
, a link bar
33
, a gear set
34
, a holding arm
35
and a bottom cover

is placed in the through hole
242
of the retaining mount
20
and has a bias spring
311
engaged therewith; and at one side of the button
31
is also provided with an abutment wing
312
.
A spring
32
is housed in a receiving cavity
243
of the retaining mount
20
. The link bar
33
has a bar embodiment
331
for insertion into the axle hole
244
of the retaining mount
20
; and at one end thereof is equipped with a rod protrusion
332
for engagement of the spring
32
; and at the opposite end is placed a retaining flange
333
.
The gear set
34
engaged with a positioning hole
245
of the retaining mount
20
is made up of an upper gear
341
and a lower gear
342
; the former is engaged with the retaining flange
333
of the link bar
33
, and the latter is in operational engagement with a rack teeth
353
of the holding arm
35
.
The holding arm
35
having an arm embodiment
352

of the holding arm
35
. At the other end of the holding arm
35
is disposed a retaining tongue
354
which is associated with a spring element
355
. Next to the retaining tongue
354
and on the holding arm is disposed a stop projection
356
. The bottom cover
36
is removably secured to the bottom of the retaining mount
20
.
Thereby, a user can place a cellular phone T

in the housing recess
21
of the retaining mount
20
when he or she stays in an indoor space, an office, or is in a vehicle. In this situation, the signal socket and power socket of the cellular phone T
1
are engaged with the signal plug
22
and the power plug
23
of the housing recess
21
. In such a manner, incoming calls of the cellular phone T
1
can be received via the peripheral equipment of the cellular phone, such as a wired telephone T
2
, resulting in reduction of direct exposure of a user to electric-magnetic waves of the cellular phone, as shown in FIG.

.
Referring to
FIGS. 1-5
, as the cellular phone T
1
is placed in the housing recess
21
, the button
31
is pressed to move downwardly with its abutment wing
312
moving against the link bar
33
. Consequently, the retaining flange
333
is urged to withdraw backward out of engagement with the upper gear
341
of the gear set
34
. As a result of the exertion of the force of the spring,
355
, the holding arm
35
pops out and is limited not to depart from the retaining mount
20
by the stop projection
356
. In a reverse manner, as the cellular phone T
1
is to be secured in place in the housing recess
21
, the holding arm
35
only has to be pushed inwardly, causing the rack teeth
353
of the holding arm
35
to mesh with the lower gear
342
of the gear set
34
. Thus the arm embodiment
352
of the holding arm
35
is made to withdraw into the retaining mount
20
to allow a cellular phone T
1
to be right fit therein. The spring
355
is in a compressed state, as shown in FIG.

and at the bottom of the seat
50
is disposed a connector plug
53
which is in coupling engagement with a modular jack
43
defined on the bottom supporting extension
401
of the retaining mount
40
.
The removable seat
50
is designed to selectively match with individual cellular phones of various types produced by different manufacturers. Each cellular phone generally has a signal socket different from others. A user only has to select a proper type of removable seat
50
to match with his or her cellular phone. If a new cellular phone is purchased, only the removable seat
50
, not the whole retaining and transmission set, is replaced.
Referring to
FIG. 10
, a hand-free device T
