Detailed Description

The present invention will be further understood by the following description of embodiments, but the specific embodiments given by the applicant should not be considered as limiting the technical solution of the present invention, and any modification of the definition of components or technical features and/or the form of the whole structure without substantial change should be considered as the protection scope defined by the technical solution of the present invention.

As shown in fig. 1 to 4, the technical scheme of the invention is as follows: a general tool comprises an L-shaped bracket 1, a supporting plate 2 and a toothed bar 3; the L-shaped bracket 1 comprises a vertical rod 4 and a transverse rod 5, wherein the vertical rod 4 is provided with a first jack, the toothed rod 3 is movably inserted into the first jack, and as a preferable mode, the toothed rod 3 is horizontally arranged; the supporting plate 2 is arranged on the transverse rod 5, the supporting plate 2 can move along the transverse rod 5, so that the distance between the supporting plate 2 and the vertical rod 4 is adjusted, a limiting device 6 is arranged at one end of the supporting plate 2, and the limiting device 6 limits the horizontal movement of the toothed bar 3 to avoid the backward movement.

Alternatively, the vertical rod 4 and the lateral rod 5 of the L-shaped bracket 1 are welded or integrally formed.

As a preferred mode, the first jack is a threaded hole, and the toothed bar 3 is provided with external threads matched with the internal threads of the first jack, so that the toothed bar 3 can be rotated forward.

As a preferable mode, the limiting device 6 comprises a positioning pin 61 mounted on the supporting plate 2, and the axis of the positioning pin 61 is consistent with the axis of the toothed bar 3;

the support plate 2 is provided with a second jack, and a first positioning device 51 is arranged in the second jack; the first positioning device 51 comprises a positioning key 511, a key slot 512 is arranged on the transverse rod 5, the first positioning key 51 can be inserted into the key slot 512 in an adaptive manner, and after the position of the support plate 2 is fixed, the positioning key 511 is used for positioning by being inserted into the key slot 512, so that the support plate 2 is prevented from moving in the vertical direction; the purpose of controlling the starting position of the toothed bar 3 to the extension length size is achieved;

as an alternative, the second jack is a threaded hole, the positioning key 511 includes a plug 5111, a steel ball 5112, and a spring 5113, where two ends of the spring 5113 are respectively a steel ball 5112 and a plug 5111, and when the plug 5111 is turned along with the internal thread of the second jack, the spring 5113 deforms to push up against the ball 5112 and insert into the key slot 512, so as to achieve positioning;
