Embodiment Construction

[0046] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0047] Combine below Figure 1 to Figure 6 The present invention will be described in detail.

[0048] A clockwork energy storage screwdriver, comprising a housing 1, a knife bar 2 and a coil spring 6, the inner end of the coil spring 6 is fixedly connected with a transmission shaft 5, and one end of the transmission shaft 5 is connected to the knife bar 2, The other end of the transmission shaft 5 is connected with a knob 7 , and the outer end of the coil spring 6 is snap-connected with the casing 1 . Rotating the knob 7 can drive the transmission shaft 5 to rotate, and the rotation of the transmission shaft 5 causes the coil spring 6 to accumulate elastic potential energy. After the screwdriver is aligned with the screw, the elastic potential energy is released, and the screw can be continu...

Abstract

The invention belongs to the field of screwdrivers, and particularly relates to a spring energy storage screwdriver. The problems that in the prior art, time and labor are wasted when a screwdriver isused for tightening a screw, and the screw cannot be continuously screwed are solved. According to the technical scheme, the spring energy storage screwdriver comprises a shell (1), a knife rod (2) and a coil spring (6); a transmission shaft (5) is fixedly connected to the inner end portion of the coil spring (6); one end of the transmission shaft (5) is connected with the knife rod (2); the other end of the transmission shaft (5) is connected with a knob (7); and the outer end portion of the coil spring (6) is fixedly connected with the shell (1). According to the spring energy storage screwdriver, continuous rotating of the knife rod can be realized through the coil spring, a user does not need to restore the positions of hands, alignment is not needed, and manpower and time are saved.The spring energy storage screwdriver is suitable for tightening or loosening various screws.

Description

technical field [0001] The invention belongs to the field of screwdrivers, in particular to a clockwork energy storage screwdriver. Background technique [0002] A screwdriver is a commonly used tool for fastening screws, which is often used in installation and maintenance. As a commonly used hardware tool, the screwdriver brings great convenience to people's life and work, saves labor costs and improves labor efficiency. [0003] When using a traditional screwdriver, it is common to use one hand to apply pressure and torque at the same time, or use two hands to operate, one hand to apply pressure and the other to apply torque. The pressure ensures the contact between the screwdriver and the cutter head, and the torsional force completes the fastening or loosening of the screwdriver. [0004] However, there are some defects in the traditional screwing method. When using one hand to apply pressure and torsion force at the same time, the user needs to separate the screwdrive...
