According to the technical solution provided by the utility model, the jack includes an outer tube and an inner tube, the inner tube is sleeved inside the outer tube, a nut is fixed on the inner tube, the nut is threadedly matched with the screw rod, and the top of the screw rod and the outer tube Rotation fit; it is characterized in that: the upper end of the screw rod protrudes from the outer tube as a power input end, and the power input end of the screw rod is connected with an electric power source or a manual power source through a connecting piece.

Further, the connecting piece includes an outer hexagonal piece, a sleeve and a sleeve rod, the outer hexagonal piece is fixedly connected to the power input end of the screw rod through a straight pin, the outer hexagonal piece is detachably connected to the sleeve, and the sleeve is connected to The sleeve rod is locked with the electric power source.

Further, the connecting piece includes an outer hexagonal piece for connecting with a manual power source, and the outer hexagonal piece is fixedly connected to the power input end of the screw rod through a cylindrical pin.

Further, the electric power source is an electric pistol drill.

Further, a fixing plate is connected outside the outer tube.

Further, the screw rod is rotatably matched with the top of the outer tube through a plane bearing.

Further, a circular iron plate is arranged on the top of the outer tube, the screw rod is rotatably matched with the circular iron plate through a plane bearing, and the upper end of the screw rod passes through the circular iron plate.

Further, a gasket is arranged between the screw rod and the circular iron plate, and a large gasket is arranged between the plane bearing and the stepped surface at the upper end of the screw rod.

The jack of the utility model solves the problems of time-consuming and laborious operation of the manual jack and high cost of the electric jack. The electric power source can be an electric pistol drill, which is very convenient, and the manual power source can be an adjustable wrench. The jack device of the utility model is not only economical but also practical, and has a great market prospect.

Detailed ways

Below in conjunction with specific accompanying drawing, the utility model is further described.

As shown in Figure 1, the jack described in the utility model includes an outer tube 11 and an inner tube 13, the inner tube 13 is sleeved inside the outer tube 11, the outer tube 11 is externally connected with a fixing plate 14, and the outer tube 11 is fixed on the outer tube 14 through the fixing plate 14. on the object that needs to be lifted; on the inner tube 13, fix the nut 12, and the nut 12 is threadedly matched with the screw mandrel 5; on the top of the outer tube 11, a circular iron plate 8 is arranged, and the screw mandrel 5 connects with the circle through the plane bearing 9 Shaped iron plate 8 rotates and cooperates, and the upper end of screw mandrel 5 passes through circular iron plate 8, and gasket 6 is set between screw mandrel 5 and circular iron plate 8, and large Gasket 10; the protruding end of the screw mandrel 5 is used as the power input end, and the protruding end of the screw mandrel 5 is fixedly connected with the outer hexagonal part 4 through the cylindrical pin 7, and the detachable connection sleeve 3 on the outer hexagonal part 4 The sleeve rod 2 is connected to the sleeve 3, and the sleeve rod 2 can be locked with the output end of the electric pistol drill 1 to realize power input.

The working process of the jack described in the utility model is as follows: the electric pistol drill 1 drives the sleeve rod 2, the sleeve 3 and the outer hexagonal piece 4 to rotate, thereby driving the screw rod 5 to rotate, and the threaded nut 12 on the screw rod 5 drives the inner The elongation of the tube 13 raises the outer tube 11, thereby realizing the lifting function.

The jack described in the utility model solves the problems of time-consuming and labor-intensive operation of the manual jack and the relatively high cost of the electric jack. The electric pistol drill is a commonly used tool and does not need to be purchased separately. It can be used directly after being locked and fixed with the sleeve rod, which is very convenient. . In the case of sudden power failure, it is only necessary to remove the sleeve rod 2 and the sleeve 3, fix the outer hexagonal part 4 with the adjustable wrench and then manually shake the screw to rotate. The adjustable wrench is also a common tool and does not need to be purchased, which is very convenient. Therefore, this new jack device is not only economical but also practical, and has great market prospects.
