[0032] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] See also Figure 1-4 The embodiment of the present invention provides a folding fascia gun, comprising a body 1 and a handle 2; the body 1 comprises a rotating cylinder 20 and an adjusting mechanism 30, the rotating cylinder 20 is rotatably connected to the handle 2 through the adjusting mechanism 30, the adjusting mechanism 30 comprises a first rotating member 3 and a connecting member 4, the first rotating member 3 is arranged on one side of the rotating cylinder 20, and the handle 2 is connected to the connecting member 4;

[0034] The first rotating member 3 of the body 1 is provided with a slot 31, a second rotating member 41 is provided on one side of the connecting member 4, and a clamping member 42 is provided on the second rotating member 41; the clamping member 42 is provided with a plurality of square blocks 421 distributed along the circumference of the second rotating member 41;

[0035] Alternatively, a clamping member 42 is provided on the first rotating member 3 of the fuselage 1, and a clamping groove 31 is provided on the second rotating member 41 of the connecting member 4; the clamping member 42 has a plurality of square blocks 421 distributed along the circumference of the first rotating member 3;

[0036] The card slot 31 includes a plurality of square grooves 311 distributed circumferentially, and the square blocks 421 match the square grooves 311 . When the body 1 is adjusted relative to the handle 2 , any one of the plurality of square blocks 421 can match the square groove 311 .

[0037] The square block 421 and the square groove 311 are rotated relative to each other by external force, thereby achieving relative rotation of the body 1 and the handle 2. The square block 421 and the square groove 311 match each other, avoiding self-locking during rotation, thereby saving the force required to adjust the angle between the body 1 and the handle 2 and making it easier to fold the body 1 and the handle 2. Due to the matching structure of the square block 421 and the square groove 311, the body 1 and the handle 2 need to overcome a certain force to rotate, but the force required is smaller than that of the prior art, thus avoiding self-locking and also preventing spontaneous rotation.

[0038] In one embodiment of the present invention, the first rotating member 3 includes an inner ring member 5 and an outer ring member 6, or the second rotating member 41 includes an inner ring member 5 and an outer ring member 6; the slot 31 is located between the inner ring member 5 and the outer ring member 6, and the slot 31 includes a plurality of square grooves 311 distributed circumferentially along the inner ring member 5 and the outer ring member 6.

[0039] The slot 31 is arranged between the inner ring 5 and the outer ring 6. The inner ring 5 and the outer ring 6 have a reinforcing effect on the slot 31, so that the anti-fracture ability of the slot 31 is enhanced, and the slot 31 is prevented from being damaged during rotation.

[0040] In one embodiment of the present utility model, a limiting groove 51 is provided on the inner side of the inner ring member 5, and a limiting portion 7 is provided on the second rotating member 41 or the first rotating member 3. The limiting portion 7 matches the limiting groove 51, and a mounting groove 73 is provided on the side of the limiting portion 7 away from the limiting groove 51. An elastic member 8 is arranged in the mounting groove 73. One end of the second connecting member 9 moves through the mounting groove 73 of the limiting portion 7 and the elastic member 8 in sequence and is connected to the limiting groove 51. The other end of the second connecting member 9 limits the elastic member 8.

[0041] By matching the limiting groove 51 with the limiting portion 7, a pre-fixing function is achieved, ensuring a reliable connection between the first rotating member 3 and the second rotating member 41 and simplifying installation. Furthermore, the distance between the first rotating member 3 and the second rotating member 41 is shortened, reducing the length of the retaining groove 31 and the clamping member 42, thereby reducing the lateral volume of the fascia gun. The elastic member 8 is used to enable the first rotating member 3 and the second rotating member 41 to overcome a certain force to achieve rotation and positioning.

[0042] In one embodiment of the present invention, a threaded hole 511 is provided at the center of the limiting groove 51, a first through hole 71 is provided at the center of the mounting groove 73 of the limiting portion 7, a second through hole is provided at the center of the elastic member 8, and the second connecting member 9 passes through the first through hole 71 and the second through hole of the elastic member 8 in sequence and is threadedly connected to the threaded hole 511 of the limiting groove 51.

[0043] In one embodiment of the present invention, the second connecting member 9 is a screw.

[0044] The elastic member 8 is used to allow the first rotating member 3 and the second rotating member 41 to rotate and engage along the circumferentially distributed square blocks 421 and the circumferentially distributed square grooves 311 when the rotating cylinder is adjusted relative to the handle, thereby achieving relative folding of the body 1 and the handle 2. When the square blocks 421 leave the corresponding square grooves 311, the elastic member 8 is compressed between the mounting groove 73 of the retaining portion 7 and the second connecting member 9. When the square blocks 421 mate with the corresponding square grooves 311, the elastic member 8 returns to press the square blocks 421 tightly within the corresponding square grooves 311. At the same time, the elastic member 8 increases the damping effect of the rotation of the body 1 and the handle 2.

[0045] In one embodiment of the present invention, there is a groove rib portion 312 between adjacent square grooves 311 . The groove rib portion 312 has a structure that is larger at the bottom and smaller at the top, so that the square groove 311 has a structure that is smaller at the bottom and larger at the top.

[0046] The structure of the groove rib portion 312 being larger at the bottom and smaller at the top means that the cross-sectional area of ​​the portion of the groove rib portion 312 close to the fuselage is larger than the cross-sectional area of ​​the portion close to the connecting member 4; the structure of the square groove 311 being smaller at the bottom and larger at the top means that the cross-sectional area of ​​the portion of the square groove 311 close to the fuselage 1 is smaller than the cross-sectional area of ​​the portion close to the connecting member 4; the square groove 311 and the square block 421 are easier to engage when matched, making the assembly of the first rotating member 3 and the second rotating member 41 simple and convenient, improving production efficiency, and being easy to use and operate, thereby enhancing user experience.

[0047] In one embodiment of the present invention, the groove rib portion 312 includes a first side wall 32 and a second side wall 33. The first side wall 32 forms a sloped structure with the bottom of the square groove 311, and the angle between the first side wall 32 and the bottom of the square groove 311 is 20-60 degrees; the second side wall 33 forms a sloped structure with the bottom of the square groove 311, and the angle between the second side wall 33 and the bottom of the square groove 311 is 20-60 degrees.

[0048] By setting the first side wall 32 and the second side wall 33 to form a structure with a slope with the bottom, on the one hand, the square groove 311 is made into a structure that is small at the bottom and large at the top. On the other hand, it is convenient for the clamping block 421 to move easily from one square groove 311 to another square groove 311 during the rotation process, thereby reducing the rotation force and avoiding self-locking.

[0049] In one embodiment of the present invention, the angle between the first side wall 32 and the bottom of the square groove 311 is 40 degrees; the angle between the second side wall 33 and the bottom of the square groove 311 is also 40 degrees.

[0050] In one embodiment of the present invention, the angle between the first side wall 32 and the bottom of the square groove 311 is 35 degrees; the angle between the second side wall 33 and the bottom of the square groove 311 is also 35 degrees.

[0051] In one embodiment of the present invention, the square block 421 has a structure that is larger at the bottom and smaller at the top, and the cross-section of the side close to the square groove 311 is smaller than the cross-section of the side away from the square groove 311. When the square block 421 is matched with the square groove 311, the smaller end of the square block 421 matches the lower part of the square groove 311, and the larger end of the square block 421 matches the upper part of the square groove 311, so as to prevent the square block 421 and the square groove 311 from being disengaged.

[0052] In one embodiment of the present invention, the elastic member 8 is a torsion spring.

[0053] In one embodiment of the present invention, the elastic member 8 is a wave spring.

[0054] In one embodiment of the present invention, the limiting portion 7 has a plurality of reinforcing ribs 72 ; the reinforcing ribs 72 are used to enhance the strength of the limiting portion 7 , so that during the folding process, the strength of the limiting portion 7 is enhanced to avoid cracks or breakage.

[0055] In one embodiment of the present invention, the folding fascia gun further includes a decorative sheet 10 , which is fixed to the outside of the second rotating member 41 . The decorative sheet 10 is used to decorate the second rotating member 41 .

[0056] In one embodiment of the present invention, the adjustment mechanism 30 further includes a third rotating member 301 . The other side of the rotating cylinder 20 is rotatably connected to the third rotating member 301 via a rotating shaft. The lower end of the third rotating member 301 is connected to the handle 2 .

[0057] In one embodiment of the present invention, the third rotating member 301 and the connecting member 4 are detachably connected, and the rotating drum 20 is rotatably disposed between the third rotating member 301 and the connecting member 4 .
