     BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a tool suspension rack, and more particularly to a magnetic suspension rack for hand-held tools. relates to sprinkling head, and more particularly to a sprinkling head of a percussive sprinkler. 
     2. Description of Related Art Including Information Disclosed Under 37 CFR 1.97 and 37 CFR 1.98 
     A conventional elongated tool suspension rack is usually hung on a wall, on a belt or hand-held. However, the suspension rack is inconvenient for a user to take and hang the suspension rack when the suspension rack is positioned on the wall. In addition, the suspension rack is heavy when being suspended on the belt with hand-held tools, and the suspension rack cannot be positioned during operating when it is a hand-held type. Consequently, some magnetic tool suspension racks are manufactured and marketed. 
     However, the conventional magnetic tool suspension rack in accordance with the prior art usually includes a rack and multiple magnetic device received in a groove defined in a bottom of the rack and each magnetic device has a seat provided for receiving a magnet. However, the seat of a conventional magnetic device has a width smaller than that of the groove. As a result, each seat needs two holders to position two opposite ends of the seat of the magnetic device for preventing the magnetic device from detaching from the rack. Consequently, the seat of the magnetic device and the holder must be accurately manufactured because the seat of the magnetic device and the holders must abut against one another and cannot be moved relative to one another. The magnetic device may detach from the rack when the holder is moved relative to the seat and separated from the seat of the magnetic device. In addition, the magnet of the conventional magnetic device directly abuts a cabinet such that the magnet may detach from the seat of the magnetic device when the magnetic effect between the magnet and the cabinet is greater than that between the magnet and the seat of the magnetic device after the rack is detached from the cabinet. 
     The present invention has arisen to mitigate and/or obviate the disadvantages of the conventional magnetic tool suspension rack. 
     BRIEF SUMMARY OF THE INVENTION 
     The main objective of the present invention is to provide an improved magnetic tool suspension rack that is position by at least one magnetic device mounted in a bottom thereof. 
     To achieve the objective, the magnetic tool suspension rack in accordance with the present invention comprises a rack having at least one groove longitudinally defined in a bottom thereof, wherein the at least one groove having the function of limiting. Multiple tool holders are slidably mounted on a top of the rack, wherein the tool holders are adapted to collect hand tools. At least one magnetic device is slidably mounted in the at least one groove, wherein at least one magnetic is limited within the groove and is adapted for positioning the rack with hand tools on a adsorbate. 
     The magnetic device is limited in the groove in the bottom of the rack by the structure thereof. Consequently, the magnetic tool suspension rack in accordance with the present invention provides no structure to prevent the magnetic device from detaching from the rack for providing a simplified structure and manufacturing processes. 
     Further benefits and advantages of the present invention will become apparent after a careful reading of the detailed description with appropriate reference to the accompanying drawings.

     DETAILED DESCRIPTION OF THE INVENTION 
     Referring to the drawings and initially to  FIGS. 1-3 , a magnetic tool suspension rack in accordance with the present invention comprises rack  10 , at least one magnetic device  20  slidably mounted in the bottom of the rack  10  and multiple tool holders  30  slidably mounted on the top of the rack  10 , wherein each tool holder  30  is adapted to hold a hand tool  40  in place. By the at least one magnetic device  20 , the rack  10  with the positioned hand tools  40  can be positioned on a magnetic cabinet (not shown) for orderly collecting hand tools  40  in a work site or on a display rack (not shown) for orderly showing the hand tools  40 . 
     Further with reference to  FIGS. 7 and 9 , the rack  10  includes a groove  11  longitudinally defined in a bottom thereof, wherein the groove  11  has a T-shaped cross-section for providing a limiting function to the magnetic device  20 . A first slide structure  12  is longitudinally formed on a top of the rack  10 , wherein the first slide structure  12  has a T-shaped cross-section. The magnetic device  20  includes a seat  21  slidably received in the groove  11 , wherein the seat  21  is made of magnetic induction material and has two engagers  22  respectively extending from two opposite sides of the seat  21 . Each engager  22  is laterally received in a corresponding one of two opposite sides of the groove  11  to prevent the seat  21  from detaching from the rack  10 . In the preferred embodiment of the present invention, the two engagers  22  are respectively from two opposite ends of a diagonal line of the seat  21 . The seat  21  has a trough  23  defined therein and a magnet  24  is received in the trough  23 . The trough  23  has a depth greater than a thickness of the magnet  24  such that a height difference H is formed between a sidewall  231  of the trough  23  and the face of the magnet  24 . The height difference H can prevent the magnet  24  from directly abutting the adsorbate (cabinet or display rack). In addition, the two opposite sides of the magnet  24  has the best magnetic effect and the two sidewalls  231  of the trough  23  respectively and directly abuts to a corresponding one of the two opposite sides of the magnet  24  such that the distal edge of each of the two sidewalls  231  of the trough  23  can enhance the magnetic effect between the magnetic device  20  and the adsorbate. Each end of the rack  10  has an end-piece  13  mounted thereon to prevent the magnetic device  20  from longitudinally detaching from the rack  10 . 
     The tool holder  30  includes a second slide structure  31  formed on a bottom of the tool holder  30  and a stub  32  extending from a top of the tool holder  30 , wherein the second slide structure  31  complementally corresponds to the first slide structure  12  and the stub  32  is adapted to be inserted into the hand tool  40 . With reference to  FIG. 7 , the first slide structure  12  is a rail and the second slide structure  31  is a groove. With reference to  FIG. 10 , the first slide structure  12  is a groove and the second slide structure  31  is a rail. 
     With reference to  FIGS. 4 to 8  that show a second embodiment of the present invention, the structures of the rack  10  and the tool holder  30  are the same as that of the first embodiment, hereinbefore. In this embodiment, there are multiple magnetic devices  50  slidably received in the groove  11 . Each magnetic device  50  includes a seat  51  made of magnetic induction material and a magnet  54  received in the seat  51 . The magnetic device  50  has a total length shorter than that of the magnetic device  10  of the first embodiment, as described above. However, the magnetic device  50  has a structure similar to that of the magnetic device  10  of the first embodiment. The seat  51  of the magnetic device  50  has two engagers  52  extending therefrom and laterally received in a corresponding one of two opposite sides of the groove  11  in the rack  10 . A trough  53  is defined in the seat  51  for receiving a magnet  54 . In this embodiment, the total length of the magnetic device  50  is greatly shortened relative to the magnetic device  20  of the first embodiment such that the magnetic devices  50  can be freely moved relative to the rack  10 . Consequently, the rack  10  with the positioned hand tool  40  can be moved relative to the adsorbate when the magnetic devices  50  are positioned on the adsorbate. Accordingly, the magnetic device  50  also can be positioned in the groove  11  in the bottom of the rack  10 . The magnetic tool suspension rack in accordance with the present further includes a stopper  60  slidably received in the groove  11  between every two adjacent magnetic devices  50  to limit the moving distance of the magnetic devices  50  or hold the magnetic devices  50  in place. As shown in  FIG. 5 , the magnetic devices  50  are positioned in the groove  11  in the bottom of the rack  10 . In addition, the magnetic tool suspension rack in accordance with the present further includes a pad  70  secured on the bottom of the rack  10  for closing the groove  11  and preventing the seat  21 / 51  from scratching the outer periphery of the adsorbate. 
     With reference to  FIG. 11  that shows a fourth embodiment of the magnetic tool suspension rack in accordance with the present invention, in this embodiment, there are two racks  10  of the first/second embodiment, as shown in  FIG. 2 / 3 , laterally and integrally connected to each other for mounting more tool holders  30  and positioning more hand tools  40 . 
     With reference to  FIGS. 12 and 13  that shown a fifth embodiment of the magnetic tool suspension rack in accordance with the present invention, in this embodiment, the rack  10 A includes a plate extending therefrom and there are multiple first slide structures  12  defined in one side of the plate  14  for slidably mounting more tool holders  30 . 
     As described above, the magnetic tool suspension rack in accordance with the present invention includes the following advantages.
         A. Simplified structure: the magnetic device  20 / 50  is limited in the groove  11  in the bottom of the rack  10  by the engager  22 / 52  extending from the magnetic device  20 / 50 . Consequently, the magnetic tool suspension rack in accordance with the present invention provides no structure to prevent the magnetic device  20 / 50  from detaching from the rack  10 .   B. Enhanced magnetic effect: the trough  23 / 53  has a depth greater than a thickness of the magnet  24 / 54  such that a height difference H is formed between the sidewall  231  of the trough  23  and the face of the magnet  24 . The height difference H can prevent the magnet  24  from directly abutting to the adsorbate and enhancing the magnetic effect of the magnetic device  20 / 50 .   C. Simplified manufacturing processes: the magnet  24 / 54  is directly positioned in the trough  23 / 53  because the seat  21 / 51  is made of magnetic induction material such that the magnetic tool suspension rack in accordance with the present invention needs no elements to hold the magnet  24 / 54  in place and the manufacturing processes of the present invention are simplified.   D. The magnet  24 / 54  in the seat  21 / 51  does not directly abut the adsorbate such that the magnet  24 / 54  is hard to be detached from the seat  51 / 51  due to the non-equivalence magnetic effect between the seat  21 / 51  and the adsorbate.       

     Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the spirit and scope of the invention as hereinafter claimed.
