In order to realize the purpose of the utility model, the utility model adopts the following technical scheme: the utility model provides a valve hand wheel appurtenance, includes brake lever and helping hand pole, hand wheel appurtenance still includes the sleeve, the brake lever respectively with the sleeve with helping hand pole links to each other, the sleeve include with hand wheel spoke matched with buckle portion.
Furthermore, the utility model discloses still provide following subsidiary technical scheme: the buckling part is of an arc-shaped structure.
The clamping part comprises an arc-surface bayonet which is used for being clamped on the side face of the hand wheel spoke.
The number of the buckling parts is consistent with that of the spokes of the hand wheel.
The boosting rod comprises a connecting part and a rotating shaft, and the connecting part is connected with the brake rod through the rotating shaft.
The connecting part is provided with a through hole matched and connected with the rotating shaft.
The brake rod end face is fixedly provided with a rotating shaft support, and the rotating shaft is rotatably arranged in the rotating shaft support.
The brake rod is provided with a groove for accommodating the power-assisted rod.
The end part of the power rod is provided with a concave part.
Compared with the prior art, the utility model has the advantages of: 1. during the use, only need with the sleeve cover establish on the hand wheel rotate the brake lever can, in the use, the valve hand wheel atress is even, can not appear loose spacious phenomenon of skidding, save time, laborsaving.
2. The boosting rod can be rotatably placed into the brake rod and can be rotated out of the brake rod when needed, so that the size of the tool is reduced, and the tool is convenient to carry.

Fig. 2 is another structural diagram of fig. 1.
Fig. 3 is a schematic view of the hand wheel auxiliary tool and the hand wheel of the present invention.
Detailed Description
The following non-limiting detailed description of the present invention is provided in connection with the preferred embodiments and accompanying drawings.
As shown in fig. 1 and 2, the utility model provides a pair of valve hand wheel appurtenance for switch valve hand wheel, including sleeve 1, brake lever 2 and helping hand pole 3, brake lever 2 links to each other with sleeve 1 and helping hand pole 3 respectively, and sleeve 1 is used for block hand wheel spoke 6, rotates helping hand pole 3 and realizes the hand wheel rotation.
Specifically, the sleeve 1 is fixedly connected with one end of the brake rod 2, and the boosting rod 3 is rotatably connected with the other end of the brake rod 2. The brake rod 2 is a hollow cylinder, and the central lines of the sleeve 1 and the brake rod 2 are the same straight line, so that the strength requirement is met, and the rapid transmission of the rotating torque is ensured.
Sleeve 1 is the cavity cylinder, and it includes along circumference evenly distributed's buckle portion 4, and 4 numbers of buckle portion are unanimous with 6 numbers of valve hand wheel spoke. The fastening portion 4 is preferably of an arc-shaped structure, and the fastening portion 4 includes a cambered bayonet 41 for being fastened to two sides of the spoke 6. Preferably, a rubber pad is attached to the bayonet 41 to prevent slipping. The number of the hand wheel spokes 6 is three, and the number of the corresponding buckling parts 4 is three.
The power-assisted rod 3 comprises a connecting part 31, the connecting part 31 is fixedly connected with the brake rod 2 through a rotating shaft 5, and the connecting part 31 is provided with a through hole matched with the rotating shaft 5. Specifically, the end face of the brake rod 2 is fixedly provided with a rotating shaft support 7, and the rotating shaft 5 is rotatably arranged in the rotating shaft support 7. The side of the brake rod 2 is provided with a groove 21 matched with the power-assisted rod 3, the power-assisted rod 3 can rotate into the groove 21, and preferably, the end of the power-assisted rod 3 is provided with a concave part 32. The number of the power-assisted rods 3 is two in the embodiment, and the two power-assisted rods are respectively arranged on two sides of the end face of the brake rod 2.
As shown in fig. 2 and 3, when the valve is used, the boosting rod 3 arranged in the groove 21 is firstly unfolded to a horizontal position, then the sleeve buckling part 4 is sleeved at the hand wheel spoke 6, and the boosting rod 3 is rotated to drive the bayonet 41 to rotate so as to open and close the valve. According to actual hand wheel structure, 4 bayonet 41 with 6 structure assorted on the hand wheel spoke of buckle portion chooseing for use, according to the valve degree of depth and tight degree of closing, brake lever 2 and helping hand pole 3 optional different length of using.
The beneficial effects of the utility model are that, during the use, only need with the sleeve cover establish on the hand wheel rotation brake lever can, in the use, the valve hand wheel atress is even, can not appear loose and spaciously phenomenon of skidding, save time, laborsaving, in the brake lever was put into to the rotatable formula of helping hand pole, rotated out the brake lever again when needing, reduced the instrument volume, convenient to carry.
