Detailed Description
The utility model is further described in connection with the following detailed description, in order to make the technical means, the creation characteristics, the achievement of the purpose and the effect of the utility model easy to understand.
The utility model provides a slotting screw of adjustable pressure, includes circular roof 1, cross groove 2 has been seted up on the top of circular roof 1, the bottom middle part welding of circular roof 1 has lead screw 3, the hollow shell 4 of inside and interior piece 5 sliding connection has all been welded to the bottom both sides of circular roof 1, the bottom of interior piece 5 has all welded spliced pole 6, fixedly connected with spring 8 between the top of interior piece 5 and the inside top of hollow shell 4, the connecting plate 12 of inside through-hole 13 of having seted up has been welded to the bottom of spliced pole 6.
The outer side wall of the circular top plate 1 is provided with threads 9, the outer side wall of the threads 9 is connected with a rotary cover 10 in a threaded manner, and the top end of the rotary cover 10 is welded with a handle 11 which is convenient for rotating the rotary cover 10.
The cross section of the inner block 5 is the same as the inner cross section of the hollow shell 4, and through grooves 7 for the connecting columns 6 to pass through are formed in the hollow shell 4.
