DETAILED DESCRIPTION

[0024] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. Example

[0025] In order to ensure the belt grinding effect and grinding safety, a belt grinding machine for hardware accessories processing is designed. The specific plan is as follows:

[0026] like Figure 1-4 As shown, a belt sander for processing hardware accessories includes a belt sander body 1, on which a clamping structure 2 is provided, the clamping structure 2 includes a fixing sleeve 201, fixedly connected to both sides of the belt sander body 1, a fixing rod 202 is slidably connected to the fixing sleeve 201, a supporting plate 203 is fixedly connected to the fixing rod 202, a rotating rod 204 is rotatably connected below the supporting plate 203, a fixing block 205 is rotatably connected to the other end of the rotating rod 204, and a clamping block 206 is fixedly connected to the bottom end of the fixing block 205.

[0027] There are two groups of rotating rods 204, and the two groups of rotating rods 204 are arranged in a mirror image with respect to the center line of the support plate 203, so as to facilitate clamping of accessories from both sides.

[0028] The two clamping blocks 206 are fixedly connected to opposite sides with a soft pad 207 , and one end of the soft pad 207 is in a wavy structure, so as to facilitate clamping of the accessories.

[0029] A connecting rod 208 is rotatably connected to the support plate 203, and the other end of the connecting rod 208 is rotatably connected to the fixed block 205; there are two groups of connecting rods 208, and the two groups of connecting rods 208 are mirror-imaged with respect to the center line of the support plate 203; thereby facilitating the increase of the stability of the movement of the fixed block 205 and the clamping block 206.

[0030] A slider 209 is fixedly connected to the bottom end of the fixed rod 202, the slider 209 and the fixed sleeve 201 are slidably connected, and a spring is fixedly connected between the slider 209 and the sanding machine body 1; thereby, the support plate 203 can be reset by the spring after sanding.

[0031] A sealing ring 210 is fixedly connected to the top of the fixing sleeve 201, and the fixing rod 202 and the sealing ring 210 are slidably connected, thereby preventing grinding dust from entering the fixing sleeve 201 and affecting the work of the spring.

[0032] A guide rod 211 is fixedly connected to the belt sander body 1, and the guide rod 211 is slidably connected to the slider 209 and the fixed rod 202, so as to facilitate the position limiting of the fixed rod 202 when it slides downward.

[0033] A rotating structure 3 is provided on the support plate 203, and the rotating structure 3 includes a fixed shaft 301, which is rotatably connected inside the support plate 203, and the fixed shaft 301 is fixedly connected to one end of the rotating rod 204, and a worm wheel 302 is fixedly connected to the fixed shaft 301, and a worm 303 is rotatably connected to the support plate 203, and the worm wheel 302 and the worm 303 are meshed; a rotating rod 304 is fixedly connected to one end of the worm 303, and the rotating rod 304 is rotatably connected to the support plate 203; thereby, it is convenient to control the state of the rotating rod 204 through the worm wheel 302 and the worm 303.

[0034] When the utility model is in use, first when it is necessary to grind the bracket accessory, the accessory to be polished can be held by hand and placed between the two clamping blocks 206 below the support plate 203, and the worm 303 is driven to rotate by rotating the rotating rod 304 on the support plate 203, and then the worm gear 302 and the worm gear 303 are meshed to drive the fixed shaft 301 fixed with the worm gear 302 to rotate, and then the rotating rod 204 is driven to rotate, so that the two sets of rotating rods 204 drive the clamping blocks 206 at the bottom ends of the fixed blocks 205 to approach each other, and the accessories are clamped and fixed by the two clamping blocks 206 and the soft pads 207 on the clamping blocks 206 to avoid the hand-held accessories from moving back and forth during grinding, which affects the grinding effect. When the rotating rod 204 drives the clamping blocks 206 on the fixed blocks 205 to move, the connecting rod 208 between the fixed blocks 205 and the support plate 203 can increase its working stability. After the accessory is fixed, the support plate 203 can be pressed on top to fix the two ends of the support plate 203. The slider 209 at the bottom end of the fixed rod 202 compresses the spring, driving the fixed rod 202 to slide in the fixed sleeve 201 through the guide rod 211, and at the same time driving the accessories clamped by the clamping block 206 under the support plate 203 to move downward. When the accessories come into contact with the grinding belt on the belt machine body 1, the support plate 203 is lightly pressed, and the accessories are polished by the grinding belt on the belt machine body 1. At the same time, the hand is pressed on the support plate 203, with a certain distance from the grinding belt, which can reduce the risk of hand being scratched. In the grinding process, the sealing ring 210 on the fixed sleeve 201 can prevent dust from entering the fixed sleeve 201 and affecting the work of the spring. When the accessories are polished, the support plate 203 is released, and the spring between the slider 209 and the fixed sleeve 201 can drive the support plate 203 to reset, and then the worm 303 is driven to rotate by the rotating rod 304, so that the two sets of rotating rods 204 on the support plate 203 are separated from each other, and the polished accessories are removed.

[0035] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
