Description

Tool mounting device

In particular, the present invention provides a one-hand reciprocating movement action by using a bearing member, so that the limit block pivoting card can be restrained at the open end of the restricting portion of the actuating groove to form a locked state or a limiting block. The pivoting device is transferred into the restricting portion of the actuating groove to form an unlocked state, thereby achieving a mounting device for a tool that is easy to be engaged in one-handed operation and access operation.

According to the specifications of the sleeve tool, after the completion of the production, the sleeve tools of different sizes are assembled on the mounting device. In addition to facilitating the display and sale of the sleeve tool, the user can conveniently carry out the installation. Access and collection.

Referring to Figures 1, 2, and 3, the U.S. Patent No. 6,581,894, the hanging tool display device of the sleeve tool includes an insertion member 10 and a hanging member 20, the insertion member 10 A hollow rectangular shell 11 is disposed, and a protrusion 111 is disposed on a sidewall of the shell 11 , and a groove 112 is respectively formed on two sides of the protrusion 111 to elastically retract the protrusion 111. The top of the housing 11 is provided with a socket 12, and the sleeve 12 is provided with a receiving slot 121, and a through slot 122 is defined in the bottom surface of the housing 121. The hanging component 20 is provided with a lifting plate. 21, the bottom of the plate 21 is provided with a set of bases 22, and an actuating plate 23 having a side edge 231 is protruded from the bottom of the set of the bases 22. The actuating plate 23 of the hanging component 20 is composed of the inserted component The slot 122 of the sleeve 12 of the 10 is inserted into the housing 11 The assembly 22 of the hanging component 20 is pivotally disposed in the receptacle 121 of the sleeve 12; please refer to FIG. 2 again, when the sleeve tool is assembled, the suspension component 20 is attached. Pivoting, the side edge 231 of the actuating plate 23 is disengaged from the inner side of the protrusion 111 of the housing 11 of the inserting member 10, so that the protrusion 111 of the housing 11 can be elastically retracted to form an unlocked state. The shell 11 can be placed in the sleeve hole of the sleeve tool, and the protrusion 111 of the shell 11 can be used to abut the groove of the sleeve hole of the sleeve tool; please refer to FIG. 3 As shown, after the housing 11 is inserted into the socket of the socket tool, the suspension member 20 is pivoted so that the side 231 of the actuation plate 23 abuts against the projection 111 of the housing 11. The inner side is formed to be in a locked state, so that the protrusion 111 of the housing 11 cannot be elastically retracted to stabilize the card against the groove of the sleeve hole of the sleeve tool, so that the sleeve tool cannot be easily The shell 11 is pulled out to provide anti-theft function when displaying the sale, or to prevent the sleeve tool from falling off when the user completes the sleeve tool; however, the hanging display device is still in use There are the following drawbacks:

1. In order to prevent the sleeve tool from being easily pulled out by the housing 11, the hanging display device pivots the hanging member 20 after the housing 11 is inserted into the socket of the sleeve tool. The side edge 231 of the panel 21 of the hanging member 20 abuts against the inner side of the projection 111 of the housing 11 to form a locked state. Therefore, for the assembly worker or the user, it is necessary to pivot with two hands. The component 20 is suspended to form a locked state, which causes trouble in the grouping operation.

2. When the user takes the sleeve tool, that is, before the sleeve tool 11 is pulled out of the sleeve tool, the user must operate the pivotal suspension member 20 with both hands to make the side of the panel 21 of the hanging member 20 The edge 231 is detached from the inner side of the bump 111 of the housing 11 to form an unlocked state, so that the sleeve tool can be smoothly pulled out. It is troublesome to use.
