DETAILED DESCRIPTION

[0034] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not used to limit the scope of the present invention.

[0035] Example 1

[0036] The present invention provides a clamp for installing and fastening a stamp, such as Figure 2-5 As shown, the seal 1 includes a seal handle 11 and a seal body 12 installed on the seal handle 11. The seal handle 11 is a cylindrical shape with a concave middle portion, that is, the seal handle 11 is a variable cross-section cylindrical shape. The diameter of the middle portion of the seal handle 11 is the smallest, and the diameter of the end of the seal handle 11 is the largest, that is, the major diameter.

[0037] The clamp comprises an adapting ring 2 , elastic claws 4 and a clamping claw ring 5 .

[0038] The adapter ring 2 is sleeved and abutted on the seal body 12. That is, the adapter ring 2 is sleeved on the seal body 12 and the circumference of the connection between the seal body 12 and the seal handle 11, and the inner wall of the adapter ring 2 abuts the seal body 12 downward.

[0039] The elastic claw 4 is a cylindrical structure, which is sleeved on the seal handle 11. An external thread 41 is provided on the outer circumference of the elastic claw 4. A claw head 42 is provided at one end of the elastic claw 4, and a connecting part 43 is provided at the other end. The connecting part 43 is inserted into the adapter ring 2 and connected to the adapter ring 2.

[0040] In order to facilitate the elastic claw 4 to firmly grasp the stamp handle 11, the number of claw heads 42 is designed to be multiple, preferably, the number of claw heads 42 is three.

[0041] Since the structural design of the present application has low requirements on the material elasticity of the claw head 42, the material of the claw head 42 can be rubber, metal or plastic, and the plastic material is preferably PVC material or polytetrafluoroethylene; the metal material is preferably a bent steel sheet, which is pre-embedded in the elastic claw 4 and then injection molded.

[0042] Since the present application is mainly aimed at copper seals, due to the high hardness of copper, the elastic claws 4 will not cause scratches or other damage to the outer wall of the seal.

[0043] The clamping claw ring 5 is sleeved on the outer circumference of the elastic claw 4 , and an inner circumferential wall of the clamping claw ring 5 is provided with an internal thread 51 , which is screwed with the external thread 41 of the elastic claw 4 .

[0044] The claw ring 5 holds the claw head 42 against the upper part of the seal handle 11, and the lower end of the claw ring 5 holds the adapter ring 2, and the seal 1 is installed and fastened in the fixture.

[0045] It should be noted that the inner diameter of the elastic claw 4 in the free state is smaller than the maximum diameter (i.e., the major diameter) of the stamp handle 11, and the elastic claw 4 is placed in the middle of the stamp handle 11 by virtue of its deformation. In other words, the multiple claw heads 42 of the elastic claw 4 are all elastic and can be deformed, and the inner diameter of the circle formed by the multiple claw heads 42 in the free state is smaller than the major diameter of the stamp handle 11. When the elastic claw 4 is pushed downward to pass through (sleeve) the major diameter of the stamp handle 11, the claw head 42 is forced to move outward, that is, the inner diameter of the circle formed by the multiple claw heads 42 is larger than the major diameter of the stamp handle 11, and the elastic claw 4 is smoothly sleeved on the stamp handle 11.

[0046] The present application adjusts the relative positions of the adapter ring 2 and the elastic claw 4 by means of the threaded cooperation between the clamping claw ring 5 and the elastic claw 4, thereby achieving the fastening of the seal 1.

[0047] In order to prevent the adapter ring 2 and the elastic claw 4 from rotating, a protrusion 21 is provided on the inner wall of the adapter ring 2, and a groove 431 is provided on the outer wall of the connecting portion 43 of the elastic claw 4. The protrusion 21 is engaged with the groove 431, so that the adapter ring 2 and the elastic claw 4 are engaged, effectively preventing the adapter ring 2 and the elastic claw 4 from rotating relative to each other.

[0048] The number of the protrusion 21 is at least one, and the number of the grooves 431 is equal to the number of the protrusions 21. Preferably, the number of the protrusions 21 and the number of the grooves 431 are both two.

[0049] Considering the length of the stamp handle 11, if the stamp handle 11 is too long, the clamp further comprises an extension ring 3, and the structure of the extension ring 3 is the same as that of the adapter ring 2. If the stamp handle 11 is too short, the extension ring 3 does not need to be assembled.

[0050] Specifically, the lower end of the clamping claw ring 5 abuts against the upper end of the lengthening ring 3 , the lower end of the lengthening ring 3 abuts against the adapting ring 2 , and the connecting portion 43 of the elastic claw 4 is inserted into the lengthening ring 3 .

[0051] In order to prevent the extension ring 3 and the elastic claw 4 from rotating relative to each other, a protrusion is provided on the inner wall of the extension ring, which engages with the groove 431 of the connecting portion 43 of the elastic claw 4 to achieve the engagement of the extension ring 3 and the elastic claw 4, thereby preventing the extension ring 3 and the elastic claw 4 from rotating relative to each other.

[0052] In order to facilitate the installation of the clamp on the printing control instrument, the clamp further includes a printing control instrument installation handle 6 , and the printing control instrument installation handle 6 is installed on the upper end of the clamping claw ring 5 .

[0053] The printing control instrument mounting handle 6 and the claw ring 5 are detachably connected, preferably by a threaded connection.

[0054] A connection structure is provided on the printing control instrument mounting handle 6. Preferably, the connection structure is a card slot 61 for mounting the printing control instrument.

[0055] Example 2

[0056] A method for installing and fastening a seal, using the clamp in Example 1, the method comprising the following steps:

[0057] Step 1: Sleeve the adapter ring 2 onto the stamp body 12 and hold it there;

[0058] Specifically, the inner wall of the adapter ring 2 is provided with a step, and the step is engaged with the corner of the seal body 12 , that is, the inner wall of the adapter ring 2 presses the seal body 12 downward.

[0059] Step 2: Sleeve the elastic claw 4 onto the stamp handle 11, and insert the connecting portion 43 of the elastic claw 4 into the adapter ring 2;

[0060] Specifically, with the claw head 42 of the elastic claw 4 facing upwards, the elastic claw 4 is forcibly pushed through the large diameter of the end of the seal handle 11, and the elastic claw 4 is sleeved on the circumference of the seal handle 11. The connecting portion 43 of the elastic claw 4 is inserted into the inner wall of the adapter ring 2, and the groove 431 of the elastic claw 4 is engaged with the protrusion 21 on the inner wall of the adapter ring 2, and the elastic claw 4 presses the adapter ring 2 downward.

[0061] If the seal handle 11 is long, the extension ring 3 needs to be installed first, and then the claw ring 5 is installed.

[0062] Step 3: Sleeve the claw ring 5 on the elastic claw 4 , and screw the internal thread 51 of the claw ring 5 into the external thread 41 of the elastic claw 4 .

[0063] Since the seal handle 11 is a cylindrical shape with a concave middle part, the internal thread 51 of the claw ring 5 is screwed together with the external thread 41 of the elastic claw 4, and the inner wall of the claw ring 5 holds the claw head 42 against the connection between the large diameter and the concave part of the seal handle 11. The connection between the large diameter and the concave part of the seal handle 11 is an arc-shaped structure, which presses the claw head 42 downward, and the claw head 42 drives the elastic claw 4 to press downward against the adapter ring 2, and the clamp clamps the seal 1.

[0064] This application has the following beneficial effects:

[0065] 1) The clamp provided by the present invention is simple and convenient to operate. It only needs to fit the adapter ring, the extension ring, the elastic claw, and the clamping claw ring in sequence, and finally tighten the clamping claw ring and the elastic claw;

[0066] 2) By designing multiple claws of the elastic claws and the inner wall of the claw ring, the claws are held against the handle, so that the clamp can firmly clamp the stamp to prevent it from loosening;

[0067] 3) By designing the adapter ring and elastic claws, the seal can be accurately fixed in the fixture, avoiding excessive correction steps and ensuring the stability of the seal during use.

[0068] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by any technician familiar with the technical field within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
