Problems solved by technology

[0002] Screws are very common parts in people's daily life. Its tightening is mostly done with a screwdriver and a wrench. Since the wrench or screwdriver can only rotate one circle at a time, the efficiency is relatively low and it is not very convenient. The existing electric fast tightening screw The equipment has not been widely used due to its high price and the need for electricity to be used.

specific Embodiment approach

[0006] Detailed Description of the Embodiments: The accompanying drawings are an embodiment of the present invention. This embodiment will be described in detail with reference to the accompanying drawings. It includes a pawl 1, a cutter head 2, a ratchet wheel 3, a spur gear 4, a rack 5, and a handle 6. With double gear 7, one end of pawl 1 is connected with a spring, and the other end is a free end. The bit 2 can be replaced with a socket wrench and various screwdriver bits. The ratchet 3 and the spur gear 4 are fixedly connected together, with straight teeth Cylindrical gear 4 and rack 5 have the same modulus. One end of handle 6 is fixedly connected to rack 5, and the other end can rotate around a fixed point. Bit 2 can be replaced with socket wrenches and various screwdriver bits; By pushing the handle 6 to drive the rack 5 to move, the rack 5 drives the double gear 7 to rotate, the double gear 7 rotates the ratchet 3 through the spur gear 4, and the ratchet 3 drives the cu...

Abstract

A manual horizontal-screw rapid tightening device comprises a pawl (1), a tool bit (2), a ratchet (3), a straight spur gear (4), a rack (5), a handle (6) and a dual gear (7), wherein one end of the pawl (1) is connected with a spring, the other end of the pawl (1) is a free end, the ratchet (3) and the straight spur gear (4) are fixedly connected, the straight spur gear (4) and the rack (5) are the same in modulus, one end of the handle (6) is fixedly connected with the rack (5), the other end of the handle (6) can rotate around one fixed point, and the tool bit (2) can be replaced with a socket spanner and various screwdriver blades. When the manual horizontal-screw rapid tightening device is used, the handle (6) is pushed to drive the rack (5) to move, the rack (5) drives the dual gear (7) to rotate, the dual gear (7) makes the ratchet (3) rotate though the straight spur gear (4), the ratchet (3) drives the tool bit (2) to rotate, and a screw can be rapidly tightened.

Description

Technical field [0001] The invention relates to a manual fast tightening horizontal screw device. Background technique [0002] Screws are very common parts in people’s lives. Most of their tightening is done with a screwdriver and a wrench. Since the wrench or screwdriver can only rotate one turn at a time, the efficiency is relatively low and not very convenient. The existing electric quick-tightening screws The equipment has not been widely used due to the high price and the need for electricity to be used. Summary of the invention [0003] The purpose of the present invention is to provide a manual quick-tightening horizontal screw device, which is used to tighten the horizontal screw, and to increase the speed of people tightening the screw. [0004] The technical scheme adopted by the present invention is: it is composed of a pawl 1, a cutter head 2, a ratchet wheel 3, a spur gear 4, a rack 5, a handle 6 and a double gear 7, one end of the pawl 1 is connected with a spring, a...
