The present invention relates to a socket holding frame assembly, and more particularly to a socket holding frame assembly having socket positioning holders being adjustable in position and in orientation and prolonging the service life thereof.
A conventional socket holding frame assembly has a track base and multiple socket positioning holders for mounting sockets. Each socket positioning holder is secured on the track base via a self-tapping screw to prevent the socket positioning holder from rotating or sliding relative to the track base.
The above-mentioned socket positioning holder is made of plastic and has a pilot hole formed at a bottom thereof. While the self-tapping screw is being driven and screwed into the pilot hole, a thread is formed at the periphery of the pilot hole by the self-tapping screw. Therefore, a threaded engagement between the self-tapping screw and the socket positioning holder is achieved. The socket positioning holder is fastened to the track base by tightening the self-tapping screw.
However, the self-tapping screw is frequently released or tightened for adjusting a position or an orientation of the socket positioning holder. The thread formed at the periphery of the pilot hole is easily worn and deformed accordingly. After long-term use and operation of the conventional socket holding frame assembly, a gap defined between the thread formed at the periphery of the pilot hole and the self-tapping screw is enlarged. Whereby, the self-tapping screw is easily stripped and loosened. The socket positioning holder cannot be firmly and stably fastened to the track base.
Moreover, if the self-tapping screw is over torqued, the pilot hole in the socket positioning holder is prone to breakage and damage. Therefore, the socket positioning holder cannot be connected with the self-tapping screw any more.
To overcome the shortcomings, the present invention tends to provide a socket holding frame assembly to mitigate or obviate the aforementioned problems.
The main objective of the invention is to provide a socket holding frame assembly that has socket positioning holders configured to slide along and rotated relative to a track base and firmly and stably fastened on the track base via a bolt for use conveniently.
The socket holding frame assembly comprises a track base and multiple socket positioning holders. The track base has a base panel being elongated and a connection hole formed through the base panel. The socket positioning holders are arranged along a longitudinal direction of the track base and slidably and rotatably connected to the track base. Each of the multiple socket positioning holders comprises a holder body, an inserted part, and a bolt. The holder is rotatably, slidably, and detachably connected to the track base and is disposed above the base panel. The inserted part is made of metal, is inserted into and combined with a bottom of the holder body, and has a threaded hole communicating with the connection hole of the track base. The bolt is inserted through the connection hole of the track base from a bottom of the base panel and is connected with the threaded hole of the inserted part to tightly fasten the holder body to the track base. The bolt includes a rod inserted through the connection hole of the track base from the bottom of the base panel and connected with the threaded hole of the inserted part via threaded engagement and a head formed at an end of the rod and disposed below the base panel.
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

The holder body 21 includes an insertion portion 213 formed at a bottom of the holder body 21. The inserted part 23 is inserted into and combined with the insertion portion 213 of the holder body 21. A bottom surface of the insertion portion 213 and a bottom surface of the inserted part 23 are located higher than a bottom surface of the holder base 211. When the bottom surface of the holder base 211 contacts the top of the base panel 11, a gap is formed between the top of the base panel 11 and the bottom surface of the insertion portion 213, hereby preventing the bottom surface of the inserted part 23 from directly contacting the top of the base panel 11. The inserted part 23 may be combined with the holder body 21 as a whole unit by insert molding. The inserted part 23 may be inserted into and combined with the insertion portion 213 of the holder body 21 by ultrasonic insertion or heat staking.

Preferably, the inserted part 23 includes a first toothed portion 235, a second toothed portion 237 located above the first toothed portion 235, and an annular groove 236 formed between the first toothed portion 235 and the second toothed portion 237. The annular groove 236 engages with the holder body 21. A plurality of engaging recesses 234 arranged around the first toothed portion 235 and a plurality of engaging recesses 234 arranged around the second toothed portion 237 engage with the holder body 21. The plurality of the engaging recesses 234 arranged around the first toothed portion 235 and the plurality of the engaging recesses 234 arranged around the second toothed portion 237 are respectively tilted toward opposite directions relative to the axis of the threaded hole 232. That is, the plurality of the engaging recesses 234 arranged around the first toothed portion 235 of the inserted part 23 of each of the multiple socket positioning holders 20 and the plurality of the engaging recesses 234 arranged around the second toothed portion 237 of said inserted part 23 respectively tilt clockwise and counterclockwise. With the arrangement of the annular groove 236 and the respective engaging recesses 234 arranged around the first toothed portion 235 and the second toothed portion 237 tilting opposite, the engagement between the inserted part 23 and the holder body 21 is further enhanced. Whereby, the inserted part 23 and the holder body 21 are hardly detached from each other when the inserted part 23 is pulled downwardly.
