Description
Technical field
The utility model relates to a kind of push-press type screwdriver, belongs to mechanical dismantling device field.
Background technology
Along with social progress and scientific and technical development, people are also more and more higher to the requirement of material life, for the large productivity that liberates mankind of can trying one's best, civilian machinery, industrial machinery, equipment manufacturing machine etc. enter daily life, all play decisive role at the aspect such as agriculture, industrial, but these machineries be unable to do without the installation of some standard rooms, a kind of new erecting tools can improve greatly its production efficiency for a manufacturing business.
Due to the limitation of conventional screw knife structure, it is limited that in the time of dismounting screw, workman imposes on the torsion of screw, and screw can not reach a good pretightning force; In addition, conventional screw-driver in order need to repeat to extract, insert this action of screw repeatedly, greatly reduces production efficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of push-press type screwdriver simple in structure, to solve the problem that pretightning force is inadequate and production efficiency is slow in the time that screw is installed.
Scheme of the present utility model is: a kind of push-press type screwdriver, comprises handle 1, unilateral bearing 2, screw rod 3, bootstrap block 4, spring 5; Unilateral bearing 2 is arranged in handle 1, and screw rod 3 is arranged in bootstrap block 4 and is threaded with bootstrap block 4, and bootstrap block 4 is arranged in unilateral bearing 2, and spring 5 is arranged on screw rod 3 and is positioned at bootstrap block 4 bottoms, and screw rod 3 two ends have interior hex slot 6.
Operation principle of the present utility model is: by lower handle 1, screw rod 3 rotates and drives the nut rotation of screw or bolt with fastenings, when completing after fastening work, spring 5 work are freely rotated unilateral bearing 2, thereby band fixed handle 1 upwards returns, pushing just can realize the degree of tightness of the standard room such as screw or bolt and so forth.
The utlity model has following beneficial effect:
1, simple in structure, can improve the operating efficiency of assembly work;
2, for the little workman of strength, can reach easily the screw pretightning force of technical requirement, can ensure the reliability of screw thread link;
3, unilateral bearing has the ability of overload protection, can protect screwdriver, screw, bolt.
