[0017] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0019] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0020] For example, Figures 1 to 3 As shown, a handheld sanding device includes a workbench 1 and a handheld sanding machine 2. The workbench 1 includes a horizontally arranged table top and a box body supporting the table top. A vacuum cleaner (not shown) is arranged in the box body and is connected to the handheld sanding machine 2 through a telescopic tube (not shown). The handheld sanding machine 2 includes a shell 21 with a built-in cavity and an opening at the bottom. The cavity is connected to the vacuum cleaner. A sanding roller 22 is rotatably arranged in the cavity. A bottom plate 23 is arranged at the opening of the shell 21. The sanding roller 22 protrudes from the bottom surface of the bottom plate 23.

[0021] In this technical solution, the top surface of the table is finely processed by a grinder or the like to ensure its roughness and avoid scratching the side of the cloth that does not need to be sanded. A conventional box can be used for the box body, and universal wheels or table corner bolts are arranged at the bottom. A door panel that can be opened and closed is arranged on the side by a hinge. When not in use, the handheld sanding machine can also be placed in the box body. When in use, the handheld sanding machine can be taken out. The vacuum cleaner and the telescopic tube are both conventional structures, so they are not described one by one. When working, the cloth is placed on the table top and fixed to the table top by hand pressure or magnetic strip clamping. The handheld sanding machine slides against the upper surface of the cloth, and the rotating sanding roller sands the surface of the cloth. The handheld sanding device has a simple structure and can be operated by hand. It is suitable for sanding small-area cloth or samples, and the hair scraps generated by the sanding are collected by a vacuum cleaner to improve the working environment.

[0022] For example, Figure 2 As shown, a motor 24 is disposed in the cavity, and the motor 24 is drivingly connected to the grinding roller 22 .

[0023] In this technical solution, the motor is fixed to the inner wall of the cavity by bolts, etc., and its output shaft passes through the side wall of the shell. The rotating shaft of the grinding roller is rotatably arranged in the shell by conventional bearings, etc., and its end close to the motor passes through the side wall of the shell. The motor and the grinding roller are driven and connected by synchronous wheels and belts, so that the motor drives the grinding roller to rotate. In order to improve the safety of use, a conventional cover can also be set outside the shell to encapsulate the synchronous belt, etc. to avoid accidents such as pinching.

[0024] For example, Figure 2As shown, a ventilation pipe 25 is provided on one side wall of the housing 21 parallel to the sanding roller 22. The ventilation pipe 25 is connected to the telescopic pipe and communicated with the cavity.

[0025] In this technical solution, the ventilation pipe is fixed to the side wall of the shell by welding or flange, and the end thereof facing away from the shell is connected to the telescopic tube by a clamp. On the one hand, the ventilation pipe serves as a handle for handheld operation, and on the other hand, it connects the cavity and the vacuum cleaner to collect the hair scraps produced by grinding and improve the working environment.

[0026] For example, Figure 2 and Figure 3 As shown, an avoidance groove 231 corresponding to the grinding roller 22 is provided in the bottom plate 23 .

[0027] In this technical solution, the avoidance groove ensures the contact between the sanding roller and the cloth, and prevents the bottom plate from interfering with the rotation of the sanding roller, thereby ensuring the sanding effect.

[0028] For example, Figure 2 and Figure 3 As shown, the two side walls of the avoidance groove 231 parallel to the grinding roller 22 are slope structures.

[0029] In this technical solution, the two side walls of the avoidance groove parallel to the sanding roller are chamfered to form a slope structure, which facilitates the entry of sanded hair into the cavity, improves the dust collection effect, and improves the working environment.

[0030] For example, Figure 2 and Figure 3 As shown, a plurality of ventilation holes 232 are respectively provided on both sides of the avoidance groove.

[0031] In this technical solution, a plurality of ventilation holes are respectively arranged on both sides of the bottom plate close to the avoidance groove, and the ventilation holes are arranged close to the avoidance groove to absorb dust from the surface of the sanded cloth.

[0032] For example, Figure 2 As shown, rotating rollers 26 are respectively provided on both sides of the housing 21 parallel to the sanding roller 22 , and the rotating rollers 26 protrude from the bottom surface of the bottom plate 23 .

[0033] In this technical solution, both ends of the rotating shaft of the rotating roller are rotatably fixed to the outer wall of the shell through mounting blocks. The rotating roller is made of a conventional rubber roller or a nylon roller sleeved on the surface of the optical axis. When in use, the handheld sanding machine slides along the surface of the fabric with the rotating roller as the rotating shaft, which is convenient for operation.

[0034] In summary, the handheld sanding device has a simple structure and can be operated by hand. It is suitable for sanding small areas of cloth or samples, and the hair scraps generated by sanding can be collected by a vacuum cleaner to improve the working environment.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0036] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
