Description

Technical Field

[0001] The utility model relates to the field of snowball clips, in particular to a snowball clip. Background Art

[0002] The snowball clamp comprises an X-shaped movable rod and a clamp shell, wherein the openings of the paired clamp shells are arranged opposite to each other, wherein the clamp shells are connected to the movable rod; the operation of clamping and throwing snow is cleverly completed through the cooperation of the X-shaped movable rod and the clamp shell, without direct contact of human hands with snow;

[0003] However, the movable rod and the chuck shell of the snowball clamp on the market are not detachable, and the user cannot replace the chuck shells of different shapes to pinch snowballs of different shapes. The snowball clamp is not very interesting. How to achieve a stable connection and convenient replacement between the movable rod and the chuck shell on the basis of the snowball clamp being able to replace the chuck shell is also a problem that designers have yet to solve. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a snowball clamp, which solves the problem that the clamping shell of the snowball clamp cannot be replaced.

[0005] The technical solution adopted by the utility model is: a snowball clamp, including a movable rod and a chuck shell, the number of the movable rod and the chuck shell are both two, the middle parts of the two movable rods are rotatably connected to each other, the movable rod includes a handle rod and a connecting rod, the connecting rod is provided with an extension plate, the extension plate is bent and provided with a positioning plate, the chuck shell is provided with an extension notch and a positioning groove that are interconnected; the extension plate is embedded in the extension notch, and the positioning plate is embedded in the positioning groove.

[0006] Through the above technical scheme, the detachable connection between the movable rod and the chuck shell is realized by the cooperation of the extension plate together with the positioning plate and the extension slot together with the positioning slot; the extension plate and the positioning plate are both arranged in a plate shape, and the contact area between the extension plate and the extension slot and the positioning plate and the positioning slot when connected in cooperation is larger, and the connection state is more stable.

[0007] Furthermore, the positioning plate extends to opposite sides at the end of the extension plate, and the cross-sectional shape of the extension plate together with the positioning plate is T-shaped; the positioning groove extends to opposite sides inside the extension groove, and the cross-sectional shape of the extension groove together with the positioning groove is T-shaped.

[0008] Through the above technical solution, when the chuck shell and the movable rod are connected, the forces on both sides of the extension plate are more even, and the connection is more stable.

[0009] Furthermore, the extension notch and the positioning groove on one chuck shell are both closed at one end close to the other chuck shell, and the extension notch and the positioning groove on one chuck shell are both open at one end away from the other chuck shell.

[0010] Through the above technical solution, when the two chuck shells perform snow clamping action and generate reverse thrust, the extension plate together with the positioning plate are squeezed toward the extension slot and the closed end of the positioning slot, thereby preventing the chuck shell and the movable rod from accidentally disengaging during the snow clamping action, and making the connection state more stable.

[0011] Furthermore, the extension plates are arranged in a strip shape, and the length directions of the two extension plates are perpendicular to the rotation axis of the movable rod.

[0012] Through the above technical solution, the length direction of the extension plate and the positioning plate is closer to the force direction, which reduces the plastic deformation or even fracture of the extension plate and the positioning plate due to the pressure generated during the activity, thereby extending the service life.

[0013] Furthermore, a pressure protrusion for pressing the chuck shell is arranged on the end surface of the connecting rod.

[0014] Through the above technical solution, after the chuck shell and the movable rod are connected to each other, the pressurizing protrusion can provide additional pressure, so that the edge of the extended groove presses against the end face of the connecting rod and the positioning plate with greater force and the connection state is more stable.

[0015] Furthermore, a pressure protrusion for pressing the chuck shell is arranged on the end surface of the connecting rod, and the pressure protrusion is arranged in a strip shape; as the pressure protrusion on one connecting rod approaches the other connecting rod, the protruding height of the pressure protrusion gradually increases.

[0016] Through the above-mentioned technical solution, after the chuck shell and the movable rod are connected to each other, the pressure-applying protrusion can provide additional pressure, so that the edge of the extended groove is pressed against the end face of the connecting rod and the positioning plate with greater force and the connection state is more stable; the protruding height of the strip-shaped pressure-applying protrusion is gradually increased, which ensures the pressure-applying effect while reducing the difficulty of connecting the chuck shell and the movable rod, making it more convenient to use.

[0017] Furthermore, a stabilizing groove is provided on one of the chuck shells, and a stabilizing protrusion is correspondingly provided on the other chuck shell; when the openings of the two chuck shells are buckled with each other, the stabilizing protrusion is inserted into the stabilizing groove.

[0018] Through the above technical solution, the stabilizing protrusion and the stabilizing groove cooperate with each other to withstand the lateral force between the two chuck shells that tend to be dislocated from each other, avoiding the mutual dislocation of the two chuck shells when they are closed, making the use state more stable.

[0019] Furthermore, a snow discharge notch is provided on the opening edge of at least one of the chuck shells.

[0020] Through the above technical solution, when using the chuck shell to pinch out a snowball, excess snow can be removed through the bleeding notch, so that the pinched snowball is closer to the shape formed inside the chuck shell. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] refer to Figure 1-Figure 4 A snowball clamp comprises a movable rod 1 and a chuck shell 2. The number of the movable rods 1 and the chuck shell 2 are both two. The middle parts of the two movable rods 1 are rotatably connected to each other. The movable rod 1 comprises a grip rod 11 and a connecting rod 12. The connecting rod 12 is provided with an extension plate 13. The extension plate 13 is bent and provided with a positioning plate 14. The chuck shell 2 is provided with an extension slot 21 and a positioning slot 22 which are connected to each other; the extension plate 13 is embedded in the extension slot 21, and the positioning plate 14 is embedded in the positioning slot 22.

[0033] The detachable connection between the movable rod 1 and the chuck shell 2 is achieved by the cooperation of the extension plate 13 together with the positioning plate 14 and the extension slot 21 together with the positioning slot 22; the extension plate 13 and the positioning plate 14 are both arranged in a plate shape, and the contact area between the extension plate 13 and the extension slot 21 as well as the positioning plate 14 and the positioning slot 22 when they are connected in cooperation is larger, and the connection state is more stable.

[0034] The positioning plate 14 extends to opposite sides at the end of the extension plate 13, and the cross-sectional shape of the extension plate 13 and the positioning plate 14 is T-shaped; the positioning groove 22 extends to opposite sides inside the extension groove 21, and the cross-sectional shape of the extension groove 21 and the positioning groove 22 is T-shaped.

[0035] This ensures that when the chuck shell 2 and the movable rod 1 are connected, the forces on both sides of the extension plate 13 are more evenly distributed, and the connection is more stable.

[0036] refer to Figure 4, the end of the extension notch 21 and the positioning groove 22 on one chuck shell 2 close to the other chuck shell 2 are both closed, and the end of the extension notch 21 and the positioning groove 22 on one chuck shell 2 away from the other chuck shell 2 are both open. This means that the relatively close ends of the extension notch 21 and the positioning groove 22 on the two chuck shells 2 are closed, and the relatively far ends are open.

[0037] When the two chuck shells 2 perform snow clamping action and generate reverse thrust, the extension plate 13 together with the positioning plate 14 are squeezed toward the extension slot 21 and the closed end of the positioning slot 22 to prevent the chuck shells 2 and the movable rod 1 from accidentally disengaging during the snow clamping action, thereby making the connection state more stable.

[0038] The extension plates 13 are arranged in a strip shape, and the length directions of the two extension plates 13 are perpendicular to the rotation axis of the movable rod 1 .

[0039] The length direction of the extension plate 13 and the positioning plate 14 is closer to the force direction, which reduces the plastic deformation or even fracture of the extension plate 13 and the positioning plate 14 due to the pressure generated during the activity, thereby extending the service life.

[0040] refer to Figure 3 A pressure protrusion 15 for squeezing the chuck shell 2 is arranged on the end surface of the connecting rod 12, and the pressure protrusion 15 is arranged in a strip shape; as the pressure protrusion 15 on one connecting rod 12 approaches the direction of the other connecting rod 12, the protruding height of the pressure protrusion 15 gradually increases.

[0041] After the chuck shell 2 and the movable rod 1 are connected to each other, the pressure-applying protrusion 15 can provide additional pressure, so that the edge of the extended slot 21 presses against the end face of the connecting rod 12 and the positioning plate 14 with greater force and a more stable connection state; the protruding height of the strip-shaped pressure-applying protrusion 15 is gradually increased, which reduces the difficulty of connecting the chuck shell 2 and the movable rod 1 while ensuring the pressure-applying effect, and is more convenient to use.

[0042] A stabilizing groove 23 is provided on one chuck shell 2 , and a stabilizing protrusion 24 is correspondingly provided on the other chuck shell 2 ; when the openings of the two chuck shells 2 are engaged with each other, the stabilizing protrusion 24 is inserted into the stabilizing groove 23 .

[0043] The stabilizing protrusion 24 and the stabilizing groove 23 cooperate with each other to withstand the lateral force between the two chuck shells 2 that tends to be dislocated from each other, thereby avoiding the two chuck shells 2 from being dislocated from each other when covered, making the use state more stable.

[0044] At least one of the opening edges of the chuck shell 2 is provided with a snow discharge notch 25 .

[0045] When the chuck shell 2 is used to pinch out a snowball, excess snow can be discharged through the bleeding notch, so that the pinched snowball is closer to the shape formed inside the chuck shell 2.

[0046] Preferably, both chuck shells 2 are provided with snow-removing notches 25 . When the two chuck shells 2 are assembled together, the two snow-removing notches 25 butt against each other and form a hole shape, so that the snow-removing action is more efficient.

[0047] The above description is only a preferred embodiment of the utility model, and does not limit the patent scope of the utility model. All equivalent structural changes made by using the contents of the utility model specification and drawings under the utility model concept, or directly / indirectly used in other related technical fields are included in the patent protection scope of the utility model.
