[0023] In the following description, a large number of specific details are given to provide a more thorough understanding of the utility model. However, it is obvious to those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0024] In order to thoroughly understand the present invention, detailed steps and detailed structures will be presented in the following description to illustrate the technical solution of the present invention. The preferred embodiments of the present invention are described in detail below, but in addition to these detailed descriptions, the present invention may also have other implementations.

[0025] Reference Figure 1 As shown, the utility model provides an easily maintainable sewing machine 100 , which includes a workbench 100 and a sewing machine head 200 .

[0026] A notch 101 is provided on one side of the table top of the workbench 100, and L-shaped lower metal slide rails 102 are symmetrically fixedly installed on both sides inside the notch 101. At least one pulley block 104 is provided on the opposite side of the lower metal slide rail 102, and the pulley block 104 has a plurality of transverse rollers 105 and longitudinal rollers 106 alternately distributed along the length direction of the slide rail.

[0027] The sewing machine head 200 is fixedly mounted on a base 201 , which is flush with the upper surface of the table top. A handle 204 is fixed to one side of the base 201 , which facilitates the sewing machine head 200 to be pulled out for maintenance.

[0028] A lateral U-shaped upper metal slide rail 202 is fixedly installed on the lower surface of the base 201. The upper metal slide rail 202 is slidably connected to the upper metal slide rail 202. The inner side of the opening of the upper metal slide rail 202 cooperates with the horizontal roller 105 and the longitudinal roller 106. Figure 4-6As shown, since the sewing machine head 200 is very heavy, the sewing machine head 200 with a slide rail design has high requirements on the load-bearing capacity. On the one hand, the present application adopts upper and lower slide rails designed with metal to ensure strength. On the other hand, transverse rollers 105 and longitudinal rollers 106 are arranged between the slide rails. The transverse rollers 105 and longitudinal rollers 106 are used to provide support and sliding guides in two directions for the upper metal slide rail 202, making its movement smoother and reducing friction resistance at the same time, so that the operator can easily pull out and push in the sewing machine head 200, which greatly reduces the difficulty and labor intensity of maintenance work.

[0029] In an optional embodiment, the rotating shafts of the transverse roller 105 and the longitudinal roller 106 are both provided with ball bearings, which further reduces the friction resistance and improves the sliding smoothness. In addition, the design of the transverse roller 105 and the longitudinal roller 106 also ensures the stability and accuracy of the sewing machine head 200 during the movement process, avoiding equipment failure or damage caused by excessive friction or loose structure.

[0030] like Figure 4 and Figure 7 As shown, a first limit block 107 is provided at the distal end of the lower metal slide rail 102, and a second limit block 203 is provided at the proximal end of the upper metal slide rail 202. The second limit block 203 cooperates with the first limit block 107 to limit the maximum outward pulling stroke of the base 201, so as to prevent the sewing machine head 200 from being excessively pulled out and affecting the stability of the slide rail or even falling out.

[0031] like Figure 8-10 As shown, a horizontal toggle clamp 300 is connected to the base 201 and one side of the workbench 100. The horizontal toggle clamp 300 is composed of a locking wrench 310 fixedly mounted on the base 201 and an M-shaped lock buckle 320 fixedly mounted on one side of the workbench 100. The locking wrench 310 is provided with a fixing bolt 311, a wrench seat 312, a wrench 313 and a movable joint 314. The fixing bolt 311 is connected to the base 201, and the wrench seat 312 is mounted on the fixing bolt 311 through a clamping block 315. The position of the wrench seat 312 in the horizontal direction is adjustable (such as Figure 8 The wrench 313 is rotatably connected to the wrench seat 312 at one end, and a protrusion 316 is provided in the middle of the wrench 313. The protrusion 316 is rotatably connected to the movable joint 314. The protrusion 316 is embedded in the middle of the M-shaped lock 320 and presses the movable joint 314 to complete the connection between the locking wrench 221 and the M-shaped lock 320. After the sewing machine head 200 is pushed back to the workbench 100, the locking wrench 310 is rotated to make it fit closely with the M-shaped lock 320, and then the base 201 of the sewing machine head is locked and connected with the workbench 100 to prevent the sewing machine head from sliding and thus ensure the stability of the sewing machine head 200 when working.

[0032] The above describes the preferred embodiments of the utility model. It should be understood that the utility model is not limited to the above-mentioned specific implementation methods, and the devices and structures that are not described in detail should be understood to be implemented in a common manner in the art; any technician familiar with the art can use the above-disclosed methods and technical contents to make many possible changes and modifications to the technical solutions of the utility model without departing from the scope of the technical solution of the utility model, or modify them into equivalent embodiments of equivalent changes, which does not affect the essential content of the utility model. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the utility model without departing from the content of the technical solution of the utility model still falls within the scope of protection of the technical solution of the utility model.
