Problems solved by technology

[0004] 1. Unable to provide effective protection against flying strikes from broken needles: Since the sewing needle moves at high speed when the sewing machine is in use, once the needle breaks, there is a danger of high-speed flying strikes, especially if it directly hits the user without obstruction When the eyes are touched, it will cause irreparable damage, and the known finger guard adopts an "L" shape to cover the sewing part, and its purpose is to block the entry of fingers. For the situation of broken needles and flying strikes, it is completely unable to provide protection.
[0005] 2. Unable to provide comprehensive protection: Since the shielding part of the finger guard is on the left side of the user, ignoring the use of the right hand push cloth, it cannot provide comprehensive protection

Embodiment Construction

[0031] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0032] Such as figure 1 , figure 2 and image 3 As shown, the main body of the present invention is a protective device 10 for preventing the flying strike of a broken needle, and has a hollow cylindrical shielding part 11, which can surround the suture needle 20 with a fixed distance at 360 degrees, so as to prevent the broken needle from any one The direction flies out; and the perforation 12 that can match the movable width of the sewing needle 20 is set at the bottom of the shielding part 11, so that the sewing needle 20 can fully exert all the functions set by the sewing machine during the sewing process.

[0033] A sheet-like extension 13 is connected to the end of the shielding portion 11 relative to the support rod 40, and its length is just to make the distance between the center point of the perforation 12 and the other end base 14 fixed to the e...

Abstract

The present invention discloses a protection device capable of preventing broken sewing-machine needle from arbitrarily flying to injure operator. It is characterized by that a transparent protection device is placed around active area of sewing-machine needle and fixedly connected on the supporting rod of presser foot, and said protection device is placed between the sewing-machine and user so as to form protection.

Description

technical field [0001] The invention relates to a protection device for preventing flying strikes of broken needles, especially a protection device applicable to sewing machines. A transparent protection device is provided between the sewing needle and the user, which can greatly improve the safety of the user . Background technique [0002] Known sewing machine protection device at present, as China Taiwan Patent Announcement No. 16891 "Sewing Machine Protection Device" novel patent case, is to set finger guard at the sewing position of sewing machine, to stop fingers from entering the direction of sewing needle and upper collar needle Sewing parts, and use the detector to stop the sewing machine under non-blocking conditions. [0003] Such a structure is designed to protect the user's fingers from extending into the action range of the needle. Looking at the above-mentioned known structure in detail, since it is not designed to prevent the flying impact of a broken needle...
