The inner wall of the gas cylinder compartment 2 is provided with a base, and the connecting portion 101 of the gas cylinder fixing clamp 1 is arranged on the base of the gas cylinder compartment 2, so that the gas cylinder fixing clamp 1 is arranged at one end of the gas cylinder compartment 2. The gas cylinder fixing clamp 1 is used for clamping the neck of the gas cylinder, so that the gas cylinder is fixed in the gas cylinder compartment 2 of the electric spraying device.

[0030] By installing the gas cylinder fixing clamp 1 at one end of the gas cylinder compartment 2 of the electric spraying device, the gas cylinder is fixed in the gas cylinder compartment 2 by cooperating the gas cylinder fixing clamp 1 with the groove at the neck of the gas cylinder. The gas cylinder fixing clamp 1 can adapt to gas cylinders of different sizes, and is convenient for installation and fixing of the gas cylinder on the electric spraying device, and is simple to operate and has a wide range of applications.

[0031] In the present application, unless specifically and particularly defined otherwise, the terms "mounting", "connecting", "connecting", "fixing" and the like should be understood in a broad sense, for example, they can be fixedly connected, or detachably connected, or integrally connected; they can be mechanically connected, or electrically connected; they can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0032] The gas cylinder storage 2 is a structure with a bottom plate and side plates, and an open top. The gas cylinder fixing clamp 1 is installed at one end of the gas cylinder storage 2, and is used to fix the gas cylinder.

[0033] The gas cylinder neck is usually provided with a neck groove. When fixing the gas cylinder, the gas cylinder is clamped on the gas cylinder fixing clamp 1 through the neck groove, so as to fix the gas cylinder in the gas cylinder storage 2.

[0034] The inner wall of the gas cylinder storage 2 is provided with a base. Here, the base is a support block or an ear seat arranged symmetrically.

[0035] In another embodiment, the gas cylinder fixing clamp 1 includes an elastic hoop clamp, a screw rod adjusting clamp, or a hinged opening and closing clamp.

[0036] When the elastic hoop clamp is used, the base provided on the inner wall of the gas cylinder storage 2 is a support block, and a screw is screwed through the connecting part 101 to the support block, so as to fix the elastic hoop clamp in the gas cylinder storage 2.

[0037] When the screw rod adjusting clamp or the hinged opening and closing clamp is used, the base provided on the inner wall of the gas cylinder storage 2 is an ear seat, the connecting part 101 is located between the two ear seats, and a screw is screwed through one of the ear seats, the connecting part 101, and the other ear seat, so as to fix the screw rod adjusting clamp or the hinged opening and closing clamp in the gas cylinder storage 2.

[0038] Specifically, the elastic hoop clamp, the screw rod adjusting clamp, or the hinged opening and closing clamp is made of aluminum alloy material, so as to realize the light weight of the gas cylinder fixing clamp 1. In other embodiments, the material can be adjusted according to specific conditions.

[0039] In another embodiment, the elastic hoop clamp includes an open ring 11 and an elastic member. The outer side wall of the open ring 11 is symmetrically provided with a connecting part 101, the open ring 11 is arranged on the base of the gas cylinder storage 2 through the connecting part 101, and the open ring 11 is open upward. The inner side surface of the open ring 11 is provided with a groove, and the elastic member is arranged in the groove. The elastic member is used to clamp the neck of the gas cylinder, so as to fix the gas cylinder in the gas cylinder storage 2 of the electric spraying device.

[0040] The outer side wall of the open ring 11 is symmetrically provided with a connecting part 101, the open ring 11 is arranged on the base of the gas cylinder storage 2 through the connecting part 101, and the open ring 11 is open upward. That is, the open ring 11 is a fixed part of the elastic hoop clamp, which is used to install the elastic hoop clamp in the gas cylinder storage 2. The open ring 11 is open upward, which provides an adjustable space for the deformation of the elastic member, so as to clamp the gas cylinder.

[0041] Among them, a groove is opened on the inner side of the open ring 11, and the elastic member is arranged in the groove; that is, when the elastic member contracts, the elastic member adapts to at least part of the groove; when the gas cylinder is installed, the elastic member expands and adapts to the entire groove to clamp the gas cylinder.

[0042] When the elastic member contracts, that is, when the gas cylinder is not clamped, the elastic member may fall off from the groove of the open ring 11, but this does not affect the overall function of use. In order to avoid this situation, and without affecting the clamping and fixation of the gas cylinder, a nylon tie is provided on the opposite side of the opening of the open ring 11, and the nylon tie is wrapped around the open ring 11 and the elastic member to fix the two.

[0043] In another embodiment, the elastic member is a first elastic buckle, which includes a main ring body 1201 and a spring arm 1301.

At this time, the main ring body 1201 is forced to expand and its diameter becomes larger, and the bottleneck groove of the gas cylinder is clamped on the main ring body 1201. Then release the spring arm 1301, and the main ring body 1201 relies on its own elastic contraction to clamp the gas cylinder so that the gas cylinder can be installed in the gas cylinder warehouse 2.

[0045] In order to facilitate the pressing operation, the spring arm 1301 is tilted relative to the cross arm, and the angle between the two is an obtuse angle.

The adjusting arm 1302 is arranged at the opening of the annular body 1202 and extends to the outside of the open ring 11. A circular hole is opened on the adjusting arm 1302, and the adjusting screw 14 is arranged on the adjusting arm 1302 through the circular hole.

[0047] During use, the distance between the two adjusting arms 1302 is increased by loosening the adjusting screw 14. At this time, the annular body 1202 expands by its own elastic force, and the bottleneck groove of the gas cylinder is clamped on the annular body 1202.

[0049] The semicircular fixed ring 15 is used to install the hinged opening and closing clamp within the gas cylinder compartment 2 via the base, while one end of the semicircular movable ring 16 is hinged to one end of the semicircular fixed ring 15. The semicircular movable ring 16 can rotate within a range of 180 degrees to open or close relative to the semicircular fixed ring 15. The other end of the semicircular movable ring 16 is provided with a fixing portion with a through hole, and the other end of the semicircular fixed ring 15 is provided with a fixing portion with a threaded hole. A fastening screw passes through the fixing portion with a through hole of the semicircular movable ring 16 and is screwed onto the fixing portion with a threaded hole of the semicircular fixed ring 15, thereby fixing and clamping the gas cylinder.

[0050] Specifically, in order to facilitate the fastening screw to be smoothly screwed into and out of the threaded hole fixing portion, the through hole of the fixing portion of the semicircular movable ring 16 is a waist-shaped hole.

[0051] When in use, loosen the fastening screws, open the semicircular movable ring 16, install the bottleneck groove of the gas cylinder on the semicircular fixed ring 15, then flip the semicircular movable ring 16 to snap it onto the semicircular fixed ring 15, and tighten the fastening screws to fix the gas cylinder on the hinged opening and closing clamp so that the gas cylinder is fixed in the gas cylinder bin 2 of the electrospraying device.

[0052] In another embodiment, the screw-adjustable clamp includes a U-shaped fixing portion 17 and a screw 18.
