BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to a displaying device or a hanger for displaying socket, connector, or linkage on a shelf. 
         [0003]    2. Description of the Prior Art 
         [0004]    Conventional hangers for displaying socket or connector are usually provided with locking functions. Therefore, unauthorized removal of the merchandise is prohibited to fight against the malice. For example, socket hanger which includes a hanging plate, a hanging piece, and an elastic slice. The hanging piece has an engagement portion at a lower portion thereof. The engagement portion is inserted in a connection hole of a socket, so that the socket is removably attached to the engagement portion. An engagement slice is then inserted into a through hole of the socket, engaging the engagement portion with a hook portion disposed at a top end of the engagement slice. A bottom edge of the engagement slice abuts against a step portion of the socket between the connection hole and the through hole. As such, the malice can not remove the socket from the engagement portion. The function of burglarproof is then achieved. 
         [0005]    However, the hangers mentioned above are not suitable for sockets or tools which have no through hole. 
         [0006]    The present invention is, therefore, arisen to obviate or at least mitigate the above mentioned disadvantages. 
       SUMMARY OF THE INVENTION 
       [0007]    The main object of the present invention is to provide a burglarproof tool hanger which performs dependable fixing, engaging, and anti-detaching functions. 
         [0008]    To achieve the above and other objects, a tool hanger of the present invention is provided for a tool to be hung thereon. The tool has a connection hole. A side wall of the tool in the connection hole is radially recessed as a groove. The tool hanger includes a hanging member and a tool holding member. 
         [0009]    The hanging member is formed with a hanging hole. 
         [0010]    The tool holding member comprises a fixation mechanism and a burglarproof mechanism. The fixation mechanism is disposed to the hanging member. One end of the burglarproof mechanism is pivotably disposed to the fixation mechanism. The burglarproof mechanism comprises a protrusion and an engagement portion. 
         [0011]    The burglarproof mechanism pivots toward the hanging member and inserts into the connection hole of the tool, so that the protrusion mates and engages the groove. The burglarproof mechanism is pushed by the tool when the tool moves toward the hanging member, so that a distal end of the burglarproof mechanism slides toward the hanging member along the fixation mechanism until the engagement portion is fixed to the fixation mechanism.

The fixation portion  211  protrudes from a foreside of the hanging member  10 , preferably from a bottom edge of the hanging member  10 . The guiding portion  212  stretches downwardly from one end of the fixation portion  211 . The fixation portion  211  includes a slant surface  211   a.  The guiding portion  212  includes several ribs  212   a.  Each rib  212   a  is formed with a slant surface  212   b.  In the present embodiment, the guiding portion includes three ribs  212   a.  The slant surface of the middle rib corresponds to the slant surface of the fixation portion, and the slant surfaces are formed with an interval therebetween. Thus, a step surface is formed between the slant surface of the middle rib and the slant surface of the fixation portion. The other ribs are formed with two hook portions  212   c,  and the ribs are arranged apart from the middle rib, located at two opposite sides of the middle rib. 
         [0025]    The burglarproof mechanism includes a first plate  221 , a second plate  222 , a protrusion  223 , and an engagement portion  224 . One end of the first plate  221  is pivotably disposed to a distal end of the guiding portion  212  away from the fixation portion  211 . One end of the second plate  222  is pivotably disposed to a distal end of the first plate  221 . An inner side of the second plate  222  is formed with several protruding portions  222   a.  Each protruding portion  22   a  is formed with a slant surface  222   b.  In the present embodiment, the second plate  222  has three protruding portions  222   a.  The middle protruding portion corresponds to the middle rib. The other two protruding portions corresponds to the other two rids, and are arranged apart from the middle protruding portion, located at two opposite sides of the middle protruding portion. On inner sides of the two protruding portions are disposed with two protruding wedging pieces  222   c.  The protrusion  223  is disposed to the second plate  22 , located at a side of the second plate opposite to the slant surface  222   b.  A first V-shaped groove  51  is formed between the first plate  221  and the guiding portion  212 . A second V-shaped groove  52  is formed between the first plate  221  and the second plate  222 . Preferably, the rib  212   a  of the guiding portion and the first V-shaped groove  51  are arranged with a gap therebetween. Similarly, the protruding portion  222   a  of the second plate and the second V-shaped groove  52  are arranged with a gap therebetween. The engagement portion  224  has a head portion  224   a  and a neck portion  224   b.  The head portion  224   a  is shrunk away from the neck portion  224   b,  so that the head portion  224   a  is formed with a slant surface  224   c.  The slant surface  224   c  of the head portion and the slant surface  222   b  of the second plate are located at same side of the tool hanger. The head portion  224   a  protrudes inwardly form the neck portion  224   b  at a border portion between the head portion  224   a  and the neck portion  224   b,  so that the head portion  224   a  is formed as a hook or a hanger. A step surface  222   d  is formed between the neck portion  224   b  and the slant surface  222   b  of the middle protruding portion of the second plate. A restriction groove  30  is defined by the head portion  224   a,  the neck portion  224   b,  and the step surface  222   d.    
         [0026]    Please refer to  FIG. 2 . The tool hanger of the present embodiment is provided for a tool to be positioned and hung thereon. In the present embodiment, the tool, such as sockets, especially the sockets provided for pneumatic tools or power tools, has a connection hole  41  axially arranged at one end. A side wall of the tool in the connection hole  41  is radially recessed as a groove  42 . However, the socket mentioned is taken for presentation and explanation only. Other types of socket or similar tool, such as connector or linkage, can be held and hung by the tool hanger. Please refer to  FIG. 2  and  FIG. 3 . For firmly positioning the socket  40  on the tool hanger, the first plate  221  of the burglarproof mechanism is firstly swung toward the hanging member  10 . Two side walls of the first V-shaped groove  51  are moved close to each other, and the first V-shaped groove  51  is diminished in width. The second plate  222  is then swung toward the hanging member  10 . Two side walls of the second V-shaped groove  52  are moved close to each other, and the second V-shaped groove  52  is diminished, also. The first plate  221  abuts against the bottom portion of the second plate  222 . When the socket  40  is moved toward the hanging member  10 , the protrusion  223  is firstly positioned in the groove  42 . The first plate  221  and the second plate  222  are moved toward the hanging member  10 . The slant surfaces  222   b  of the protruding portions abut against and slide along the corresponding slant surfaces  212   b  of the ribs of the guiding portion. When the second plate  222  continuously slides toward the hanging member  10  and the head portion  224   a  touches the fixation portion  211 , the slant surface  224   c  of the head portion abuts against and slides along the slant surface  211   a  of the fixation portion. During the slide, the region or thickness where the second plate  222  overlapping the guiding portion  212  is getting larger until a top surface of the fixation portion  211  abuts against a bottom surface of the head portion  224   a.  Then the fixation portion  211  engages the restriction groove, and the wedging pieces  222   c  engage the corresponding hook portions  212   c,  as shown in  FIG. 4  and  FIG. 5 . Since then, the total thickness of the second plate  222  and the guiding portion  212  reaches a predetermined maximum value which fits for the inner diameter of the connection hole of the socket. Thus, the burglarproof mechanism is engaged and stuck on the fixation mechanism so as to hold the socket tightly on the tool hanger. Unpredictable removal is then prohibited, as shown in  FIG. 6 . Please refer to  FIG. 7 . After customers possess the socket lawfully, the head portion  224   a  can be removed by a knife or shears. The fixation portion  211  is then released from the restriction groove, and the socket  40  can be removed from the tool hanger easily. 
         [0027]    In another embodiment of the present invention, the guiding portion may be formed with a rectangular appearance, with no slant surface thereon. The contact surface of the second plate to the guiding portion may be a perpendicular surface. The contact surfaces of the fixation portion and the head portion may be perpendicular surfaces, also. However, the functions of engaging and holding the tool can still provided by the tool hanger. 
         [0028]    Accordingly, the tool hanger provides the function of burglarproof. In addition, the tool hanger is provided fitting for various tools.
