     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     Please refer to  FIGS. 1 and 2 . The present invention provides a battery cover  2  of a wireless mouse, which is provided in a body  1  of the wireless mouse. The battery cover  2  includes a plate  20 , an accommodating trough  21 , an insertion hole  22 , and a fixing portion  23 . 
     The bottom of the body  1  of the wireless mouse is provided with a battery accommodating chamber  12  for accommodating an electricity unit such as a battery (not shown), thereby providing the necessary electricity for the wireless mouse. 
     The surface of the plate  20  is recessed to form the accommodating trough  21 . One side of the plate  20  is provided with the insertion hole  22  that is in communication with the accommodating trough  21 . The fixing portion  23  is formed by means of extending from a side wall surface forming the insertion hole  22 . 
     The plate  20  covers the battery accommodating chamber  12  of the body  1  in such a manner that it can be pivotally lifted from or cover the bottom of the body  1 . Alternatively, the plate can be engaged in the bottom of the body  1 . 
     More specifically, as shown in  FIGS. 1 to 3 , in the case of pivotal connection, both sides of the plate  20  are provided with a pivot  24  respectively. The body  1  is provided thereon with two pivotal holes  14  for corresponding to the two pivots  24 , thereby pivotally connecting the plate  20  to the bottom of the body  1 . Further, both sides of the plate  20  extend to form hooks  25  that correspond to troughs  16  formed on sides of the body  1 . Via the above arrangement, when the plate  20  covers the bottom of the body  1 , the engagement of the hooks  25  with the troughs  16  can allow the plate  20  to be fixed to the body  1 . The pivotal connection in the present invention is not limited to the above way as long as the plate  20  can be pivotally connected to the body  1 . 
     Alternatively, as shown in  FIGS. 5 to 7 , in the present embodiment, the pivots  24  and the pivotal holes  14  mentioned in the previous embodiment are not provided. Instead, hooks  25  are formed on both sides of the plate  20 . With the hooks being hooked in the corresponding troughs  16  of the body  1 , the plate  20  can be engaged in the bottom of the body  1 . 
     In the present embodiment, the accommodating trough  21  of the plate  20  can accommodate a wireless receiver  3 . The wireless receiver  3  has a front end  31 . When the wireless mouse is to be connected with a personal computer, the front end  31  of the wireless receiver  3  is inserted into a USB port (not shown) of the personal computer.

     Further, in the embodiment of the present invention shown in  FIGS. 1 to 4 , only one fixing portion  23  is provided, which is integrally connected to both side wall surfaces of the insertion hole  22 . Alternatively, as shown in  FIGS. 5 to 8 , two fixing portions  23  are provided, which extend from the side wall surfaces of the insertion hole 
     Further, an elastic arm  26  extends from a side wall of the accommodating trough  21  for abutting against a side wall of the wireless receiver  3  elastically, thereby fixing the wireless receiver  3  more firmly. 
     According to the above, in the battery cover  2  of the wireless mouse, the plate  20  covers the battery accommodating chamber  12  provided in the bottom of the body  1 . The plate  20  is provided with an accommodating trough  21  for accommodating a wireless receiver  3 . The insertion hole  22  of the plate  20  allows a front end  31  of the wireless receiver  3  to be extended therein to turn off the power switch  19 , thereby saving electricity. Further, in comparison with prior art that the wireless receiver is disposed in the wireless mouse, the present invention utilizes the fixing portion  23  to fix the front end  31  of the wireless receiver  3 , and thus it is unnecessary to provide an upper cover on the wireless mouse. This arrangement may not cause any inconvenience to the user and will not occupy the internal space of the wireless mouse. As a result, it is more advantageous to reduce the overall volume of the wireless mouse and arrange other elements therein.
