detailed description

The technical solution of the utility model is further specifically described below through the embodiments and in conjunction with the accompanying drawings.

Example:

A household manual simple jack as shown in the figure has a screw rod 1, a bracket 4, a top cover 5, a lifting lever 3, and a lifting sleeve 2; the screw, bracket, top cover, lifting lever, and lifting sleeve have the same center Wire.

The bottom of the screw rod 1 is fixed with a dish-shaped chassis 12 as a base; the top of the screw rod 1 is fixed with a knob 11, which can be

Rotate directly manually or with a wrench to lift the lifting sleeve 2 and the supporting platform 21 on the lifting sleeve along the screw rod 1, and adjust the initial height of the supporting platform 21 according to the height of the object.

The section of the bracket 4 and the top cover 5 is groove-shaped, the bracket 4 is arranged on the bottom of the screw rod 1, the top cover 5 is arranged on the top of the screw rod 1, and a screw hole is provided in the middle of the bottom of the groove for cooperating with the screw rod 1. A lifting lever 3 is installed between the bracket 4 and the top cover 5, the notch is inward, and the outer spacing of the notch is slightly smaller than the inner spacing of the lifting sleeve 2, thereby playing a guiding role in lifting the lifting sleeve.

A connecting piece 41 is respectively hinged on both sides of the grooved edge of the bracket 4 .

The lifting lever 3 includes a connecting body 33, a rod body 32 and a power handle 31; the power handle 31 is connected to one end of the rod body 32; the longitudinal section of the connecting body 33 is U-shaped, and the bottom surface is fixedly connected to the other end of the rod body 32 , the upper part of the open end of the U-shaped surface is the resistance point of the lifting handle 3, and the resistance point is provided with a lifting hole 34, and the below of the U-shaped surface is a fulcrum, and the fulcrum is provided with a fulcrum hole 35;

In the installed state, the lifting lever 3 is hinged to the bracket 4 via the fulcrum hole 35 through the connecting piece 41 on the bracket.

The lifting sleeve 2 is a transparent cylinder with three sides closed and one side open, and the cross section is groove-shaped. Set table 21, in order to bear the function part, and each has a connecting hole on the other two sides;

In the installed state, the connecting hole is connected with the lifting hole 34 on the fulcrum of the lifting lever 3 using a pin shaft 6 .
