FIELD OF THE INVENTION [0001] The present invention relates generally to a child car seat with an armrest, and more particularly to a child car seat with an adjustable armrest. BACKGROUND OF THE INVENTION [0002] As shown in FIG. 1, a conventional child car seat 1 with an adjustable armrest disclosed in U.S. patent laid open No. 2004/0070244 A1 comprises a conventional seat base 11 and two conventional armrests 13 mounted with the seat base 11 respectively at two (lateral) sides of the seat base 11. The conventional seat base 111 has two cavities 111 respectively at two end of the seat base 11 and two sets of eyelets 112 formed in different heights on the wall surface which defines each of the cavities 111. Each conventional armrest 13 has an elastic flag 131 and two bulges 132 perpendicularly extending away from the elastic flag 131. Each conventional armrest 13 can be adjusted in height relative to conventional seat base 11 by making the bulges 132 be received in different sets of eyelets 112. [0003] However, the elastic flag 131 described above is typically made of plastic and integrally molded together with the conventional armrest 13. Therefore, elastic fatigue may occur in the elastic flag 131 due to frequent adjustment of the armrest in height and aging effect. The elastic fatigue will result in the bulges 132 being unable to be engaged with the seat base 11 in the eyelets 112 so that the function of adjusting the armrest 13 in different heights might be lost. Furthermore, in order to facilitate operation of adjustment, the bulges 132 are typically formed arc. But, the arc bulges 132 have negative effect of being unable to be firmly accommodated in the eyelets 112 especially when the bulges 132 are worn out due to frequent adjustment operation. This drawback may incur danger for a user when the armrest is suddenly lowered down while she/he puts her/his arm on the armrest 13. Besides, it is inconvenient for a user to press the bulges 132 with two fingers or with bigger force due to the conventional way of adjustment. SUMMARY OF THE INVENTION [0004] Accordingly, the present invention relates to a child car seat with an adjustable armrest that is substantially intended to obviate one or more of the problems due to the limitations and disadvantages encountered in the prior art. [0005] One object of the present invention is to provide a child car seat with an adjustable armrest where elastic fatigue is unlikely to occur in the elastic piece thereof so that the function of adjusting the armrest in different heights can be long maintained. [0006] Another object of the present invention is to provide a child car seat with an adjustable armrest whose element for adjustment is unlikely to be worn out so that the armrest can be firmly secured at desired height. [0007] Yet another object of the present invention is to provide a child car seat with an adjustable armrest where the operation of adjustment is easy and effortless. [0008] Additional features and advantages of the invention will be set forth in the description which follows, and in portion will be apparent from the description, or may be learned by practice of the invention. The objectives and advantages of the invention will be realized and attained by the structure as particularly set forth in the written description and claims as well as illustrated in the appended drawings. [0009] To achieve these and other advantages and according to the purpose of the present invention, as embodied and broadly described, a seat with an adjustable armrest, the seat comprising: a seat base having a mounting port; the armrest partially received within the mounting port, and having a longitudinal passage and a plurality of lateral slots situated on a side of the passage; and a controlling piece which is slidably engaged with the seat base and has an actuating portion, a guiding portion extending away from the actuating portion and slidably received within the passage, and a wing laterally extending from the guiding portion; wherein when the wing is received within one of the slots, the armrest is blocked from being moved and is held at a predetermined height relative to the seat base, and when the wing is not received within the slots, the armrest can be moved relative to the seat base. [0010] In a preferred aspect, the seat further comprises an elastic piece which is mounted between the controlling piece and the seat base so as to bias the controlling piece. [0011] Moreover, the controlling piece further has a bump connected with the guiding portion, and a total thickness of the bump and the wing being bigger than width of one of the slots. [0012] It is another preferred feature that the controlling piece further has a bump connected with the wing, and a total thickness of the bump and the wing being bigger than width of one of the slots. [0013] Additionally, the seat further comprises a backrest mounted with the seat base. [0014] Furthermore, the seat further comprises an intermediate piece which is engaged with the seat base, and the controlling piece is slidably engaged with the intermediate piece. [0015] It is preferred that the intermediate piece has a chamber and a channel which is opened into the chamber, the actuating portion of the controlling piece is received within the chamber, and the guiding portion is received within the channel and the passage. [0016] It is preferred that the seat further comprises an elastic piece which is mounted between the controlling piece and the intermediate piece so as to bias the controlling piece. [0017] It is preferred that the controlling piece further has a bump connected with the guiding portion, and a total thickness of the bump and the wing being bigger than width of one of the slots. It is preferred that the controlling piece further has a bump connected with the wing, and a total thickness of the bump and the wing being bigger than width of one of the slots. [0018] It is preferred that the seat further comprises a backrest mounted with the seat base. [0019] It is to be understood that both the forgoing general description and the following detailed description are exemplary and explanatory and are intended to provide a further non-limiting explanation of the invention as claimed. BRIEF DESCRIPTION OF THE DRAWINGS [0020] The accompanying drawings, which are included to provide a further understanding of the invention and are incorporated in and constitute a portion of the specification, illustrate embodiments of the invention and together with the description serve to explain the principle of the invention.
