Detailed Description
The present invention will be further described with reference to the accompanying drawings and embodiments.
Referring to fig. 1-4 in combination, in an embodiment of the present invention, the fastening member for securing the connection includes: a mounting block 1; fixing mechanism, fixing mechanism locates on installation piece 1, fixing mechanism includes cavity 2, cavity 2 sets up on installation piece 1, two lead screws 3 are installed to cavity 2 internal rotation, two lead screws 3 all extend to one side of installation piece 1, be equipped with two worm wheels 4 in cavity 2, two worm wheels 4 respectively with corresponding lead screw 3 fixed connection, cavity 2 internal rotation is installed worm 5, worm 5 and two worm wheel 4 homogeneous phase meshing, fixed mounting has first conical gear 6 on the worm 5, cavity 2 internal rotation is installed dwang 7, dwang 7 extends to one side of installation piece 1, be equipped with second conical gear 8 in cavity 2, second conical gear 8 with dwang 7 fixed connection, second conical gear 8 with first conical gear 6 meshes mutually, one side of the mounting block 1 is provided with a clamping plate 9, and the two screw rods 3 penetrate through the clamping plate 9 and are in threaded connection with the clamping plate 9.
Through setting up fixed establishment, realized the firm connection to the work piece, and can not take place not hard up phenomenon easily.
And a crank handle 10 is arranged on one side of the mounting block 1, and the crank handle 10 is fixedly connected with the rotating rod 7.
Through setting up crank 10, conveniently directly rotate dwang 7, avoid using tools to be favorable to the use of this device.
Through setting up sawtooth 11, increased the frictional force between installation piece 1 and splint 9 and the work piece, prevented the work piece and this device relative slip to make the connection of work piece more firm.
