In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a ball valve with adjustable, includes valve body and spanner subassembly, and spanner subassembly drives the internal case of valve through connecting the valve rod and rotates, and spanner subassembly includes mount pad, bracing piece and locating part, and the valve rod is connected to the mount pad, and a plurality of spacing grooves have been seted up to the bracing piece side, and the through-hole has been seted up to the mount pad side, and the bracing piece inserts in the through-hole rather than sliding connection, still has seted up the spacing hole of intercommunication through-hole on the mount pad, and the locating part inserts from the spacing hole and supports to the spacing inslot on the bracing piece.

Further, the limiting piece comprises a blocking cap, a limiting rod, a limiting seat and a spring, wherein the blocking cap is in threaded connection with the limiting hole, the limiting rod penetrates through the blocking cap to be propped into a limiting groove on the supporting rod, the limiting seat is arranged on the limiting rod on the inner side of the blocking cap, and the spring is arranged between the blocking cap and the limiting seat.

Further, the limit groove is of a conical structure, and the bottom of the limit rod is connected with a conical block matched with the limit groove.

Further, the limit grooves are uniformly formed in the side faces of the support rods.

The beneficial effects of the utility model are as follows:

according to the utility model, the use requirements in different occasions are met by arranging the adjustable wrench, and when the wrench is pulled and the wrench cannot be rotated due to smaller force, the moment arm can be increased by lengthening the wrench, so that the moment is increased; when the space is relatively narrow, the length of the wrench can be properly shortened according to the size of the space, so that the operation is convenient; and the position of the wrench is limited by the limiting piece, so that the wrench is prevented from slipping when in use.

Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Referring to fig. 1-4, the adjustable ball valve provided by the utility model comprises a valve body 1 and a wrench assembly 2, wherein the wrench assembly 2 drives a valve core in the valve body 1 to rotate by connecting a valve rod, the wrench assembly 2 comprises a mounting seat 201, a support rod 202 and a limiting piece 203, the mounting seat 201 is connected with the valve rod, a plurality of limiting grooves 2021 are formed in the side surface of the support rod 202, a through hole 2011 is formed in the side surface of the mounting seat 201, the support rod 202 is inserted into the through hole 2011 and is in sliding connection with the through hole 2011, a limiting hole 2012 communicated with the through hole 2011 is formed in the mounting seat 201, and the limiting piece 203 is inserted into and propped against the limiting groove 2021 on the support rod 202 from the limiting hole 2012.

Further, the limiting piece 203 comprises a blocking cap 2031, a limiting rod 2032, a limiting base 2033 and a spring 2034, the blocking cap 2031 is in threaded connection with the limiting hole 2012, the limiting rod 2032 passes through the blocking cap 2031 to be abutted into the limiting groove 2021 on the supporting rod 202, the limiting base 2033 is arranged on the limiting rod 2032 on the inner side of the blocking cap 2031, and the spring 2034 is arranged between the blocking cap 2031 and the limiting base 2033.
