DETAILED DESCRIPTION

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] Please also refer to Figures 1 to 3 Now, a presser foot for conveniently fixing a button 4 provided by the present invention will be described. The presser foot for conveniently fixing a button 4 comprises: a presser foot body 1, a limiting block 2 and two clamping assemblies 3. The front end of the presser foot body 1 is provided with a receiving groove 101 for placing the button 4; the limiting block 2 is installed on the rear side of the receiving groove 101, and the rear side of the button 4 contacts the limiting block 2; the two clamping assemblies 3 are symmetrically arranged on the left and right sides of the receiving groove 101; the clamping assembly 3 comprises a rotating rod 301, a clamping block 302 and an elastic member 303; the rotating rod 301 is rotatably installed on the presser foot body 1 in the horizontal direction, the clamping block 302 is fixedly installed on the rotating rod 301, and the elastic member 303 applies a force to the rotating rod 301 so that the clamping block 302 presses against the outer wall of the button 4.

[0028] This embodiment provides a presser foot for conveniently securing a button 4. Compared to the prior art, a limit block 2 and two clamping assemblies 3 are mounted on a presser foot body 1. When a button 4 is placed in a receiving slot 101, the rear side of the button 4 contacts the limit block 2. The clamping blocks 302 in the two clamping assemblies 3 exert a force on the outer side wall of the button 4 under the elastic force of an elastic member 303. The limit block 2 and the two clamping blocks 302 clamp and secure the button 4 horizontally, thereby preventing the button 4 from shaking within the receiving slot 101.

[0029] In some embodiments, see Figure 3, the elastic member 303 is a torsion spring. In this embodiment, a through slot for installing the rotating rod 301 is provided on the pressing foot body 1, and the through slot is opened along the left and right directions of the pressing foot body 1. A support shaft is fixedly installed on the pressing foot body 1, and the support shaft is arranged in the vertical direction. The support shaft is located in the through slot, the rotating rod 301 is installed on the support shaft, and the torsion spring is installed between the rotating rod 301 and the support shaft. One end of the rotating rod 301 extends into the accommodating groove 101. The clamping block 302 is welded and fixed to one end of the rotating rod 301 located in the accommodating groove 101. The torsion spring applies a force to the rotating rod 301 to move the two clamping blocks 302 toward each other.

[0030] In some embodiments, see Figures 1 to 3 An operating rod 304 is fixedly mounted on the rotating rod 301, and the operating rod 304 extends to the outside of the pressing foot body 1. In this embodiment, the operating rod 304 is welded to the rotating rod 301. One end of the operating rod 304 extends to the outside of the pressing foot body 1, making it convenient for the operator to hold the operating rod 304. The operator first holds the operating rod 304 to drive the rotating rod 301 to rotate around the axis, so that the two clamping blocks 302 move away from each other, and then places the button 4 in the receiving groove 101. When the operator does not apply force to the operating rod 304, the rotating rod 301, under the action of the torsion spring, drives the clamping block 302 to move toward the side close to the button 4 and abut against it, finally achieving the fixation of the button 4.

[0031] In some embodiments, see Figure 3 A flexible sleeve 305 is mounted on the gripping end of the operating rod 304. In this embodiment, the sleeve is fixed to the gripping end of the operating rod 304, which is located outside the pressing foot body 1. The flexible sleeve 305 is made of sponge. Due to its elasticity, it can improve the operator's comfort when gripping the operating rod 304.

[0032] In some embodiments, see Figure 3 A flexible ring 306 is mounted on the outer side of the clamping block 302, and the flexible ring 306 contacts the outer side wall of the button 4. In this embodiment, the clamping block 302 is cylindrical and arranged vertically. The flexible ring 306 is mounted and fixed on the clamping block 302. The flexible ring 306 is made of rubber. The clamping block 302 contacts the outer side wall of the button 4 through the flexible ring 306, so the clamping block 302 and the button 4 are in flexible contact, thereby preventing rigid collision between the two.

[0033] In some embodiments, see Figure 3 and Figure 4The outer circumferential surface of the clamping block 302 is provided with an annular groove 307 for mounting the flexible ring 306. In this embodiment, the flexible ring 306 has a certain elasticity and is capable of undergoing a certain degree of elastic deformation. Therefore, the flexible ring 306 is mounted within the annular groove 307 by virtue of its own elasticity. The annular groove 307 serves as a position limiter for the flexible ring 306, thereby maintaining a relatively stable position of the flexible ring 306 on the clamping block 302.

[0034] In some embodiments, see Figure 1 and Figure 3 A pressing block 308 is installed on the top of the clamping block 302, and the pressing block 308 contacts the top surface of the button 4. In this embodiment, the forces applied by the limiting block 2 and the clamping block 302 to the button 4 are both in the horizontal direction. The pressing block 308 is fixedly installed on the top of the clamping block 302. When the clamping block 302 abuts against the outer wall of the button 4, the pressing block 308 covers the top edge of the button 4, thereby limiting the vertical freedom of the button 4 and further improving the stability of the button 4 in the receiving groove 101.

[0035] In some embodiments, see Figure 4 and Figure 5 , a first magnet 309 is installed at the bottom of the pressing block 308, and a second magnet 310 corresponding to the first magnet 309 is installed on the clamping block 302. In this embodiment, a mounting groove for mounting the pressing block 308 is provided on the top surface of the clamping block 302. A portion of the pressing block 308 is located in the mounting groove, and the other portion extends above the button 4 and contacts the top surface of the button 4. The first magnet 309 is fixedly mounted on the bottom surface of the pressing block 308, and the second magnet 310 is fixedly mounted on the bottom surface of the above-mentioned mounting groove. The first magnet 309 and the second magnet 310 correspond to each other up and down. The pressing block 308 is fixedly connected to the clamping block 302 by magnetic attraction, and the connection structure is simple and easy to assemble and disassemble.

[0036] In some embodiments, see Figure 1 、 Figure 2 and Figure 6 , the limit block 2 is slidably installed on the foot pressing body 1 in the horizontal direction, and a screw 201 is installed on the rear side of the foot pressing body 1. The screw 201 is connected to the limit block 2 by a thread, and the screw 201 drives the limit block 2 to move in the direction close to or away from the button 4. In this embodiment, the limit block 2 is a rectangular block. A rectangular groove that slides with the limit block 2 is provided on the foot pressing body 1. The rectangular groove is opened along the front and back directions of the foot pressing body 1. The screw 201 remains parallel to the limit block 2. The screw 201 is connected to the foot pressing body 1 by a bearing, and the screw 201 is connected to the limit block 2 by a thread. When the drive screw 201 rotates, it can drive the limit block 2 to move in the direction close to or away from the button 4, thereby adapting to the installation of buttons 4 of different sizes.

[0037] In some embodiments, see Figure 2 and Figure 6 An operating handle 202 is installed at one end of the screw 201 located on the pressing foot body 1. In this embodiment, the operating handle 202 is hingedly installed at the end of the screw 201 located outside the pressing foot body 1. A slot 203 for installing the operating handle 202 is provided at the end of the screw 201. The hinge axis of the operating handle 202 is perpendicular to the rotation axis of the screw 201. When the operating handle 202 is needed, the operating handle 202 is rotated to be perpendicular to the screw 201; when the operating handle 202 is not needed, the operating handle 202 is stored in the slot 203 to avoid misoperation of the screw 201.
