Manual screw for support of electronic drum

Abstract

The invention discloses a manual screw for a support of an electronic drum. The manual screw comprises a screwing handle, a screw seat and a lead screw which are integrally manufactured; the screw seat is arranged in the middle part of the bottom end of the screwing handle; the lead screw is arranged in the middle part of the bottom end of the screw seat; a front sunken area is formed in one side of the front end surface of the screwing handle, and while a front convex area is formed in the other side of the front end surface of the screwing handle; the part in which the front sunken area is connected with the front convex area is in smooth transition; a rear convex area is formed in one side of the rear end surface of the screwing handle, opposite to the front sunken area, and while a rear sunken area is formed in the other side of the rear end surface of the screwing handle; the part in which the rear sunken area is connected with the rear convex area is in smooth transition. The manual screw is integrally manufactured and is stable in structure and long in service life; the front end surface and the rear end surface of the screwing handle are of a wave-shaped concave-convex structure, a user can hold the sunken areas in two end surfaces with the thumb and the index finger to rotate, thus the working stability is ensured, and the fingers can be avoided injury; in addition, the humanized design improves the experience of a user on use.

Description

technical field [0001] The invention relates to a screw, in particular to a thumb screw used on an electronic drum bracket. Background technique [0002] Thumb screws are commonly used on electronic drum brackets, especially on the adjustment rod of the electronic drum bracket. The clamp on the adjustment rod is generally tightened by hand screw. A threaded hole is formed on the top, and the screw rod is screwed into the threaded hole to form a thumb screw together with the handle. When in use, the clamp is tightened by driving the screw through the handle, but the handle is often made of plastic, while the screw is made of metal. If a little force is used during use, the handle is easily damaged. After long-term use, There will be looseness between the screw rod and the threaded hole of the handle, which affects the use and has a low service life. In addition, in order to increase the friction between the fingers and the handle, anti-slip lines are often engraved on the s...
