Preferably, the first protrusion is provided with a limiting part, the second protrusion is provided with a limiting groove, and the limiting part is matched with the limiting groove.
Through adopting above-mentioned technical scheme, the spacing groove that sets up on the locating part that sets up on the first arch and the second arch mutually supports for first arch and second arch are spacing each other, make first arch and second arch can not take place the displacement, thereby make bolt stability more.
Preferably, the rod sleeve comprises a sleeve body and a tightening piece, wherein the tightening piece comprises a tightening belt and a fastener, and the tightening belt surrounds the rod sleeve and is movably connected with the fastener.
Through adopting above-mentioned technical scheme, tighten up the cover body through the packing piece for the cover body firmly restricts the first body of rod and the second body of rod in the loop bar, thereby makes the screw rod more stable.
Preferably, the tighteners are symmetrically arranged about the stem.
Through adopting above-mentioned technical scheme, through the receipts chucking spare that the symmetry set up for the better first body of rod and the restriction of second body of rod of cover body are in the loop bar.
Preferably, a positioning bulge is arranged in the loop bar, positioning grooves are arranged on the first bar body and the second bar body, and the positioning grooves are matched with the positioning bulges.
Through adopting above-mentioned technical scheme, through constant head tank and the protruding cooperation of location for first body of rod and the better quilt of the second body of rod are fixed.
Compared with the prior art, the beneficial effects of the utility model are that: the first protrusion on the first rod body and the second protrusion on the second rod body are matched with each other, so that the length of the screw rod can be adjusted, the screw rod is fixed through the sleeve rod after the position required by the screw rod is adjusted, and the application range of the rod piece is enlarged.

Detailed Description
In the following description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like refer to the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of the description, but do not refer to or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus are not to be construed as limiting the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1, a length-adjustable stud, including screw rod 1 and rod cover 8, screw rod 1 includes the first body of rod 2 and the second body of rod 3, the first body of rod 2 is connected with the dismantlement of the second body of rod 3 through rod cover 8, the first body of rod 2 is provided with the first arch 4 of echelonment in the loop bar, the second body of rod 3 is provided with the second arch 5, first arch 4 is mutually supported with the second arch 5, rod cover 8 is including the cover body and the piece of tightening up, the piece of tightening up is including tightening up area 9 and fastener 10, tightening up area 9 encircle rod cover 8 and with fastener 10 swing joint.
When the length of the screw rod 1 is not enough, the tightening belt 9 is loosened by loosening the fastener 10, the spacing between the sleeve body and the first rod body 2 and the second rod body 3 is cancelled, the sleeve body is separated from the first rod body 2 and the second rod body 3, the first rod body 2 and the second rod body 3 can be detached, thereby adjusting the first protrusion 4 on the first rod body 2 and the second protrusion 5 on the second rod body 3, so that the first protrusion 4 and the second protrusion 5 are pressed on steps with different heights, the length is extended, so that when the length of the screw rod 1 is not enough, the pressing point of the first bulge 4 and the second bulge 5 can be changed, the length of the screw rod 1 is prolonged, thereby promote the application scope of product, let the better different environment of adaptation of product to inside arch supports each other and presses, makes the holding power between the screw rod 1 still stable.
Set up locating part 6 on first arch 4, set up spacing groove 7 on second arch 5 for spacing groove 7 and locating part 6 block each other, thereby make first arch 4 and second arch 5 can not appear sliding on the support pressure step of difference, make the holding power of screw rod 1 more stable, make the product more reliable. And set up the protruding 11 of location and set up constant head tank 12 on the first body of rod 2 and the second body of rod 3 in the loop bar, it is spacing with the mutual block of constant head tank 12 through protruding 11 in location for the circumstances that drops can not appear in first arch 4 and the protruding 5 of second, make the product more stable durable, and through the receipts chucking piece that the symmetry set up, make the single body of rod of better control of product, make the operation more convenient.
In conclusion, when the screw rods 1 with different lengths are needed, the contact surfaces of the first protrusions 4 and the second protrusions 5 are changed, so that the length of the screw rods 1 is changed, requirements of different lengths are better met, and the application range of products is widened.
