Embodiment Construction

[0023] refer to figure 1 , shows a foldable handle according to a first embodiment of the present invention. The foldable handle includes a handle body 10 having two ears 11 and 12 formed thereon and at least one extension rod 20 connected to the handle body 10 . The handle body 10 may include a slot 19 for receiving the extension rod 20 therein when the handle is in the folded position.

[0024] refer to figure 2 , shows a perspective view of the handle body 10 seen from the front. exist figure 2 , a boss or pin 13 arranged on the inside of the ear 11 is shown, the pin 13 preferably surrounding a centrally located hole or opening 16 . Said hole 16 not only extends through the pin 13 but also through the ear 11 below the pin 13 . The pin 13 can have one or more grooves 15 in its radial direction. In other words, the opening 15 is substantially perpendicular to the hole 16 . In a preferred embodiment, the other ear 12 may also have a pin formed thereon.

The foldable handle comprises a main body, an extension rod and a button, wherein the main body is provided with a first auricular member, a second auricular member and a lug, and the lug is provided with a first slot and is formed on the first auricular member; the extension rod is provided with a third auricular member which is connected to the lug pivotally, and a second slot is formed in the third auricular member; the button is provided with a bulge, the bulge is connected with the first slot and the second slot so as to lock the main body and the extension rod in proper positions, and the bulge and the slots are separated to unlock the main body and the extension rod; and the button penetrates through the lug in an extension way when the foldable handle is assembled.

Description

technical field [0001] The present invention relates to collapsible handles, and more particularly, to a handle extension with position locking for vehicle jacks. Background technique [0002] It is common to see collapsible handles in vehicle jack sets or tool boxes. Considering that the collapsible handle will rotate along the connection point between the handle arms during use, it is preferable for such a handle to have a locking function which can lock the collapsible handle in a fixed position after extension. [0003] US Patent No. 7,237,463 B1 discloses a bendable wrench, which includes a handle, a head and a pivot. A pivot shaft is movably inserted into the ear of the head and the handle to pivotally connect the two. The pivot includes multiple teeth that engage the teeth of the ear to firmly maintain the angle between the head and the ear, and are disengaged from the teeth of the head so that the angle between the head and the handle can be changed . Similarly, ...
