CROSS REFERENCE TO RELATED APPLICATIONS 
     This application is a national phase application of PCT/CN2011/079720, filed on Sep. 16, 2011. The contents of PCT/CN2011/079720 are all hereby incorporated by reference. 
     BACKGROUND 
     1. Technical Field 
     The present application relates to a golf training apparatus, and in particular, to a movable golf coach box. 
     2. Related Art 
     Currently, a well-known golf training system is formed by a square platform and a fixed operating box connected to each other, the platform producing a slope under a hydraulic pressure function. The system has the disadvantages of a relatively large volume and non-mobility. In particular, it cannot be placed on a grass sod for use, and the adopted alternating current (AC) electricity and the hydraulic pressure go against safety and environmental protection. Only an up-slope, a down-slope, a left-slope, and a right-slope are provided without a device for simulating a swing plane. A training condition for a special golf lie is not essentially provided. Currently, another well-known golf training system is a circular iron hoop formed by a metal tube and connected to a ground fixation footboard via two support poles, a metal rolling rod being used for simulating a swing action on the iron hoop. The system has the disadvantages that a golf club cannot be used on the iron hoop for batting training because the club may be damaged, a batting effect cannot be sensed by using the rolling rod, and a golf swing arc is not a perfect circle.

     DETAILED DESCRIPTION 
     The following describes the present application in detail in combination with the preferable specific embodiments with reference to the accompanying drawings. 
     Embodiment 1 
     As shown in  FIG. 1  to  FIG. 4 , a golf coach box in this embodiment includes a batting box  1  and a swing plane sliding rail  2 . The batting box takes a circular shape on the whole and the swing plane sliding rail  2  takes an arch shape on the whole. A lifter pin base  101  is fixed to one end of an outer edge of the batting box. A lifter pin  1001  is mounted, capable of being lifted up and down, in the lifter pin base  101 . A free end of the lifter pin  1001  is connected to a lifter pin connecting plate  1002  provided at a central point of the swing plane sliding rail  2 . The swing plane sliding rail  2  is provided with telescopic rod retaining pins at positions close to both ends thereof, and is detachably connected via the retaining pins to a free end of a telescopic rod  102 . The other end of the telescopic rod  102  is connected to retaining pins separately provided at two side edges of the batting box  1 . After the swing plane sliding rail  2  and the batting box  1  are connected via the telescopic rod, an included angle between the swing plane sliding rail  2  and the batting box  1  can be adjusted conveniently by adjusting a telescoping degree of the lifter pin  101  and the telescopic rod  102 . The included angle preferably has a maximum value of 65° and a minimum value of 0° (in non-use state when the included angle is 0°), thereby adapting to batting requirements for different clubs. Swing plane sliding rail reset fixation mechanisms  103  are further provided on the two side edges of the batting box  1 . When it is unnecessary to use the swing plane sliding rail  2 , the swing plane sliding rail  2  may be reset and fixed to the outer edge of the batting box by detaching the telescopic rod  102  and moving the lifter pin  1001 , so that this coach box can serve as a training box for the user to conduct batting without the swing plane sliding rail. 
     The method for using the swing plane sliding rail of the golf coach box of the present application is: a user correctly grips a club and stands on the batting box  1 , erects a portion of the club near a club head on the swing plane sliding rail  2 , and sways the club up and down along the swing plane sliding rail  2  to bat a ball during the swing, so as to master swing concepts. 
     As shown in  FIG. 4  and  FIG. 5 , the swing plane sliding rail  2  of the present application includes a swing plane sliding rail body formed by an outer guard plate  201 , an inner guard plate  202  and a square tube  203 , a square rubber shock absorption pad  204 , a nylon strip track  205 , a swing rhythm display  206 , and a U-shaped groove  210 , a recess  209 . The outer guard plate  201  is wider than the inner guard plate  202 . The outer guard plate  201  and the inner guard plate  202  are connected and fixed to each other via the square tube  203 . After the fixation, the U-shaped groove  210  is formed above the square tube  203 . The width of the square rubber shock absorption pad  204  is approximate to the opening width of the U-shaped groove  210 , so that the square rubber shock absorption pad can be just clamped in the U-shaped groove  210 . The height of the square rubber shock absorption pad  204  is greater than the depth of the U-shaped groove  210 , so that an upper end of the square rubber shock absorption pad  204  is higher than top ends of the inner guard plate  202  and the outer guard plate  201  after the square rubber shock absorption pad  204  is clamped in the U-shaped groove  210 . The upper end of the square rubber shock absorption pad  204  is provided with the recess  209  for mounting the nylon strip track  205 . The nylon strip track  205  is fixed in the recess  209  with elasticity of the square rubber shock absorption pad  204 . The swing rhythm display  206  includes a plurality of LED indicator lights. The LED indicator lights are arranged on a lower end of the inner guard plate  202  and may be fixed thereto via the inner guard plate  202  or the square tube  203 . In practice, the LED indicator lights may also be mounted at an inner side of the outer guard plate  201 . On-off control of all the plurality of LED indicator lights is performed by the same control chip. A swing rhythm is indicated by controlling lighting-up and lighting-off of the LED lights. For example, all the LED indicator lights are turned on in advance and then are turned off from a top end of the swing plane sliding rail  2  in sequence, and a swinger controls a club and a swing speed so that the club is always maintained at a joint between a turned-off LED light and a turned-on LED light. To satisfy training requirements, different lighting-off speeds may be set in the control chip. In a further solution, a control chip with a remote receiver may be adopted and the remoter is utilized to switch among different lighting-off speeds, so as to facilitate user&#39;s operations. 
     The nylon strip track  205  is preferably made of a nylon material with a smooth surface. In this embodiment, a transparent or a semi-transparent hollow nylon strip track is adopted, a flexible neon line  208  (also referred to as an Electroluminescent (EL) wire) passes through the hollow of the nylon strip track  205 , and a battery is utilized to supply power to the EL wire. During use in night, the EL wire is turned on, so that a user can clearly view a swing track thereof. The EL wire is preferably an EL wire which takes a green appearance and emits green light. 
     The function of the square rubber shock absorption pad  204  lies in buffering a pressure of the club on the swing plane sliding rail  2  and reducing abrasion of the club caused by the swing plane sliding rail  2 . 
     In this embodiment, segmentation marks with different color patterns are coated on the inner guard plate and the outer guard plate of the swing plane sliding rail. The segmentation marks include one or more of a start swing segment mark, a back swing segment mark, a down swing segment mark, a release segment mark, a batting segment mark and a forward swing segment mark, used for prompting a user to master a swing arc and control a carry of the ball. 
     As shown in  FIG. 1 ,  FIG. 2 ,  FIG. 3 , and  FIG. 6 , in this embodiment, the body of the batting box  1  is formed by a batting mat  104 , a lifter disk  105 , a base plate  106 , a lifter mechanism, and an organ-type dust shield  107 . The lifter disk  105  is a steel plate taking a circular shape on the whole. The batting mat  104  is placed on the lifter disk  105 . A lifter pin connecting plate  207  is provided on one side of the lifter disk  105 . The side of the lifter disk  105  where the lifter pin connecting plate  207  is provided is rotatably connected to one side of the base plate  106 . The lifter mechanism is provided between the lifter disk  105  and the base plate  106  and is used to control ascending and descending of the lifter disk  105 , so that a certain slope angle is formed for the lifter disk  105  with respect to the horizontal plane. The lifter mechanism may adopt various lifter mechanisms which are well known by persons skilled in the art, as long as the effect that a certain slope angle is formed for the lifter disk  105  with respect to the horizontal plane can be achieved. As shown in  FIG. 6 , in this embodiment, the lifter mechanism adopts a cam lifter device. A DC motor  005  is utilized to drive sector cams  002  to rotate to control a distance between the lifter disk  105  and the base plate  106 , so as to achieve ascending and descending of the lifter disk  105 . The following describes the specific structure of the cam lifter device. 
     Three bracket bearings  003  are fixed on the base plate  105  separately. The three bracket bearings  003  are positioned at the same straight line. A cam shaft  004  is fixed by the three bracket bearings  003 . One end of each of two sector cams  002  is separately fixed on each of two ends of the cam shaft  004 . Four rolling wheels are mounted on a sector surface of each sector cam  002  separately. The rolling wheels are used to press against a lower surface of the lifter disk, so that a transmission connection between the sector cams  002  and the lifter disk is formed. The cam shaft  004  is driven to rotate by the DC motor  005  via a chain  006 . A gear reducer  007  is further provided between the DC motor  005  and the chain  006 . The DC motor  005  is powered by a 12-V DC power supply  001  and is controlled by a breakpoint brake  010  to turn on or off. The lifter principle of the lifter mechanism is: the lifter disk  105  is stabilized on the base plate  006  by depending on support of the rolling wheels on the two sector cams  002 . Moreover, a difference in contact position and angle between the rolling wheels on the sector cams  002  and the lifter disk  105  may cause a difference in distance between the lifter disk  105  and the cam shaft  004 , namely, a difference in distance between the lifter disk  105  and the base plate  106 . Therefore, when the DC motor  005  drives the cam shaft  004  and further drives the cams  002  to rotate, contact positions between the cams  002  and the lifter disk  105  also change accordingly, and further a lifter effect is formed. The lifter mechanism further includes synchronizing wheels  017  and belts. The synchronizing wheels  017  are provided on the cam shaft  004  in a sleeve way. One end of each belt is fixed to each synchronizing wheel  017  and the other end thereof is fixed to the lifter disk  105 . A proper length is set for the belts, so that the belts may be rolled up around the synchronizing wheels  017  due to rotation of the cam shaft  004  when the lifter disk  105  descends, and that the belts are unrolled due to rotation of the cam shaft  017  when the lifter disk  105  ascends, where the length of the belts after the unrolling is equal to the distance between the lifter disk and the base plate, thereby preventing the lifter disk  105  from entirely departing from the base plate  106  due to an external force no matter where the lifter disk is located. In this embodiment, the lifter mechanism is further provided with a low level control switch  011  and a high level control switch  012 , used to control forward rotation and reverse rotation of the DC motor  005 , so as to control ascending and descending of the lifter disk. Power supply input ends of the low level control switch  011  and the high level control switch  012  both are electrically connected to an output end of a lifter controller  013 . The lifter controller  013  controls on-off of the low level control switch  011  and the high level control switch  012 . A power supply input end of the lifter controller  013  is connected to the DC power supply  001 . A buzzer  014  and a buzzer  015  are provided respectively between the lifter controller  013  and the low level control switch  011  and between the lifter controller  013  and the high level control switch  012  and are used to prompt that ascending and descending are being performed. A lifter indicator light  016  is electrically connected to the lifter controller  013 . When the lifter controller  013  works, the lifter indicator light  016  emits light to prompt that the lifter mechanism is performing the ascending and descending. In specific implementation, a remote device may be adopted to control the lifter controller  013 , so as to facilitate user&#39;s operations. 
     As shown in  FIG. 3 , in this embodiment, a rotating disk  108  and at least two rotating wheels  109  are provided at the bottom of the base plate  106  of the batting box  1 . A lower surface of the rotating disk  108  is positioned at the same horizontal plane with grounding points of the rotating wheels  109 . The batting box  1  is placed on an indoor floor or an outdoor grass sod via the rotating disk  108  without fixation with an auxiliary facility, thereby achieving mobility of the coach box. Since the lower surface of the rotating disk  108  and the grounding points of the rotating wheels  109  are positioned at the same horizontal plane, rotation of the batting box  1  can be achieved as long as the batting box  1  is slightly pushed without uplifting the whole batting box  1 . Moreover, the collaboration between the rotating disk and the lifter mechanism may enable the batting box to simulate at least nine different batting slopes. 
     As shown in  FIG. 3 , two laser addressing devices  110  are further provided in parallel on the base plate  106  of the batting box  1 . The laser addressing devices  110  adopt laser addressing devices whose light paths can be adjusted, and preferably, adopt laser addressing devices which emit green light beams, so as to guide user&#39;s practice of a stance during batting setup and a club face during target addressing. 
     Embodiment 2 
     The difference between this embodiment and Embodiment 1 only lies in the design of the base plate and the rotating disk. The base plate of Embodiment 1 still seems slightly cumbersome although the base plate can achieve rotation of the batting box  1  through collaboration between the rotating disk and the rotating wheel. The design of the base plate in this embodiment makes the rotation of the batting box lighter, more convenient, and safer. 
     As shown in  FIG. 7  and  FIG. 8 , in this embodiment, the base plate  106  is a circular steel plate. The base plate is fixed on a rotating disk. The rotating disk includes an upper support tray  1061  and a lower support tray  1062 , the upper support tray  1061  being rotatably fixed to the lower support tray  1062 . The specific structure of the base plate is described below. The lower support tray  1062  is an eight-claw-shaped steel frame, formed by eight support arms connected to an octangle steel plate, where a central position of the octangle steel plate is provided with a bearing base  1063 , and an end of each support arm is provided with a roller  1064 . The upper support tray  1061  is also an eight-claw-shaped steel frame, formed by eight support arms  1067  connected to an octangle steel plate, where a central position of the upper support tray  1061  is provided with a bearing  1065  corresponding to the bearing base  1063 , and a circular rail  1066  corresponding to the roller  1064  is fixed on each support arm. An upper support arm  1061  and a lower support arm  1062  may be connected together in a relative rotating manner through collaboration between the bearing  1065  and the bearing base  1063  and between the roller  1064  and the rail  1066 . An upper surface of the upper support arm  1061  is connected to the base plate  1061  in a fixation way. The rotation of the batting box can be achieved as long as the batting box is slightly pushed when it is necessary to rotate the batting box. 
     It is necessary to further provide a gyration braking mechanism between the upper support tray  1061  and the lower support tray  1062 , used to fix a relative position between the upper support tray  1061  and the lower support tray  1062  when it is unnecessary to rotate the batting box. The braking mechanism may be achieved by adopting a plurality of forms. For example: corresponding pin holes are provided on the upper support tray  1061  and the lower support tray  1062 , and when it is unnecessary to rotate, the braking can be achieved by passing a pin through the corresponding pin holes provided on the upper support tray  1061  and the lower support tray  1062  at the same time. 
     The above content further describes the present application in the specific preferable embodiments in detail, but it cannot be considered that the specific embodiments of the present application are only limited to the above description. Person skilled in the art to which the present application belongs may make some equivalent replacements or obvious variations without departing from the inventive concept of the present application, and the performance and uses are the same, all of which should fall into the protection scope of the present application.
