Problems solved by technology

As for forward and reverse reversing, manual adjustment is required, the ratchet cannot be achieved by loosening the screws, and the minimum turning angle is large
And defects such as many parts, complex mechanism, and high cost also set obstacles to the wide application of ratchet batches.

Embodiment Construction

[0012] The present invention will be further described below in conjunction with accompanying drawing.

[0013] In the figure: one or more gears 5 with the same thickness, the same spacing and the same number of teeth are arranged on the wall of the batch rod 1. The gear 5 and the batch rod 1 can be a whole, or can be connected with the batch rod 1 One. A round hole 4 is provided on one end of the handle 10, and the inner wall of the round hole 4 is provided with a ring-shaped protrusion. The number, number of teeth, and spacing of the 5 gears on the same batch rod 1 are the same, and all teeth of the gear 5 on the batch rod are all meshed with each other. The inner ring gear 6, one end of the batch rod 1 is inserted into the circular guide hole 9 provided at the inner end of the inner ring gear 6, a spring 8 is arranged between the bottom of the round guide hole 9 and the end face of the batch rod 1, and the spring 8 and the batch rod 1 Steel balls 7 can also be established ...

Abstract

The invention discloses a ratchet batch, aiming at providing a ratchet batch, in which a loosening screw can be normally used even without a positive and negative adjusting button and the screw can be randomly unloaded tightly positively and negatively by a single hand with a small screwing angle. The ratchet batch has advantages of large torsion force, small size, simple structure and easy processing and manufacturing. The ratchet batch comprises a rod, gearwheels, annular gears and a spring. The working principle of the ratchet batch is that: the method is applied in the ratchet batch that the gearwheels and the annular gears, both of which have the same number of teeth, are adopted to mesh each tooth of the two gearwheels and the meshed teeth of the two gearwheels are separated axially; with this method, the work performance of the ratchet batch is improved. The invention is applicable for fast unloading tightly the screws on various machineries, electronic equipment and apparatuses.

Description

technical field [0001] The invention relates to a manual tool for tightening and unloading screws, in particular to a ratchet set with large torque and fast operation. Background technique [0002] At present, the known ratchet batch structure is made up of batch bar, small ratchet, ratchet plate, reversing button, handle etc. Because the ratchet is small, the pawl sheet is thin. Therefore, when the force is slightly larger, the teeth often jump, and even the ratchet teeth and pawls are damaged to affect the work. Such as Chinese patent ratchet screwdriver (200520015369.6); a kind of ratchet screwdriver (00259415.3) etc. As for the forward and reverse reversing, manual adjustment is required, and the ratchet cannot be achieved by loosening the screws, and the minimum turning angle is large. And defects such as many parts, complex mechanism and high cost have also set obstacles for the wide application of ratchet batches. Contents of the invention [0003] In order to o...
