[0010] The handle is provided with a placement slot on its periphery, in which two extension rods are movably fitted, each of which is semi-annular and has one end rotatably connected to the placement slot via a rotating shaft;

[0011] A clamping block is clamped on each side of the clamping gear, a fixing groove is opened in the clamping block, a fixing block is movably engaged in the fixing groove, a slider is fixedly connected to the bottom of the fixing block through a rotating shaft, a sliding groove is opened on the side of the valve body close to the slider, and the slider is movably engaged with the sliding groove.

[0012] Preferably, a semicircular first limiting groove is formed at one end of the extension rod, a first limiting block is movably engaged with one end of the first limiting groove, and the first limiting block is welded to the movable rod.

[0013] Preferably, a first elastic member is provided on one side of the fixing blocks that are close to each other, and the first elastic member is movably fitted in the fixing groove.

[0014] Preferably, a stopper is movably engaged with the clamping block above the fixing groove, and one end of the stopper extends to the outside of the clamping block.

[0015] Preferably, second limiting blocks are welded on both sides of the stop block, and second limiting grooves are opened on both sides of the clamping block close to the stop block.

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1-6 , a mechanical hydraulic valve, comprising:

[0030] Valve body 1;

[0031] The valve body 1 is rotatably connected to a movable rod 2 via a bearing;

[0032] A handle 3 welded to the movable rod 2;

[0033] A card gear 4 connected to the movable rod 2 via a fastener;

[0034] The handle 3 is provided with a placement groove 6 on its periphery. Two extension rods 7 are movably fitted in the placement groove 6. The extension rods 7 are semi-annular in shape. One end of the extension rod 7 is rotatably connected to the placement groove 6 via a rotating shaft.

[0035] There is a card block 5 on each side of the card gear 4, and a fixed groove 12 is opened in the card block 5, and a fixed block 13 is movably engaged in the fixed groove 12. The bottom of the fixed block 13 is fixedly connected to the slider 11 through a rotating shaft. A slide groove 10 is opened on the side of the valve body 1 close to the slider 11. The slider 11 is movably engaged with the slide groove 10. The movable rod 2 can control the valve in the valve body 1. The handle 3 can drive the movable rod 2 to rotate. The movable rod 2 can drive the card gear 4 to rotate. The extension rod 7 can be rotated on the handle 3. The fixed block 13 can slide in the fixed groove 12. The slide groove 10 is a circular ring. The slider 11 can rotate around the card gear 4 along the slide groove 10, thereby helping the card block 5 to embed into the card gear 4.

[0036] Specifically, a semicircular first limiting groove 8 is opened at one end of the extension rod 7 , a first limiting block 9 is movably engaged with one end of the first limiting groove 8 , and the first limiting block 9 is welded to the movable rod 2 .

[0037] Through the above technical solution, the first limit groove 8 can slide on the first limit block 9. As the extension rod 7 rotates one hundred and eighty degrees, the extension rod 7 can be engaged by the first limit block 9, so that the handle 3 can be rotated through the extension rod 7.

[0038] Specifically, a first elastic member 14 is provided on one side of the fixing blocks 13 that are close to each other. The first elastic member 14 is movably fitted in the fixing groove 12 .

[0039] Through the above technical solution, the first elastic member 14 can push the fixing block 13 by its own elastic force, so that the clamping block 5 is embedded in the clamping gear 4.

[0040] Specifically, a stopper 15 is movably engaged with the clamping block 5 above the fixing groove 12 , and one end of the stopper 15 extends to the outside of the clamping block 5 .

[0041] Through the above technical solution, the block 15 is used to block the fixed block 13. When the movable rod 2 needs to be rotated, the two blocks 5 can be separated. At this time, the fixed block 13 will first squeeze the block 15, so that the block 15 moves up until the fixed block 13 passes over the block 15. At this time, the block 15 will block the fixed block 13 to prevent the block 5 from rebounding and re-engaging the gear 4.

[0042] Specifically, second limiting blocks 17 are welded on both sides of the stopper 15 , and second limiting grooves 16 are formed on both sides of the clamping block 5 close to the stopper 15 .

[0043] Through the above technical solution, the stopper 15 can drive the second limiting block 17 to move.

[0044] Specifically, the second limiting block 17 is movably engaged with the second limiting groove 16 , and a second elastic member 18 is provided on the top of the second limiting block 17 .

[0045] Through the above technical solution, the second limiting block 17 can slide in the second limiting groove 16 .

[0046] Specifically, the second elastic member 18 is movably fitted in the second limiting groove 16 .

[0047] Through the above technical solution, the second elastic member 18 can push the second limiting block 17 by its own elastic force, and further push the stopper 15 to be embedded in the fixing groove 12.

[0048] When the lever 2 is in the unlocked position, the locking block 15 is pulled upwards and the locking block 15 is no longer blocked by the fixing block 13, thereby enabling the locking block 5 to re-engage the gear 4 under the action of the second elastic member 18. If the tooth position is incorrect at this time, the locking block 5 can be rotated along the slide groove 10 to help the locking block 5 engage the gear 4 to prevent the movable rod 2 from rotating accidentally when no one is around.
