[0033] The technical solutions in the embodiments of the present application will be apparently and completely described in conjunction with the drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0034] As shown in the figure, the present application discloses an adjustable follow-up opening tightening gun head, which comprises two clamps 1, the rear end of the two clamps 1 is connected with a gun head seat 3 through a pin 1, the lower end of the gun head seat 3 is provided with a clamp lock 4, the rear end of the clamp lock 4 is arranged in a gun head cylinder seat 5, the rear part of the clamp lock 4 is connected with a cylinder 6, the output end of the cylinder 6 penetrates through the gun head cylinder seat 5, the front end of the clamp 1 is provided with a pin 2, the lower end of the pin 2 is provided with a roller 8, the front end of the clamp lock 4 is provided with a limiting groove 41, the lower end of the roller 8 is located in the limiting groove 41, and the inner wall of the clamp 1 and the gun head seat 3 are provided with a spring 9.

[0035] When the clamp needs to be closed, the spring 9 is compressed, when the two clamps need to be opened, the cylinder 6 works to push the clamp lock 4 to move forward, the roller 8 moves forward along the limiting groove 41, at this time, the spring 9 resets to drive the front end of the clamp to rotate outward around the pin 1, so as to realize opening. When the two clamps need to be closed, the cylinder 6 drives the clamp lock 4 to move in the opposite direction.

[0036] In an embodiment of the present application, the pin 1 penetrates through the gun head cylinder seat 5.

[0037] In an embodiment of the present application, the front end of one of the clamps 1 is provided with a recess 1, the front end of the other clamp 1 is provided with a recess 2, when the two clamps 1 are in the closed state, the recess 1 and the recess 2 form a circular hole, at this time, the spring 9 is in the compressed state. A standard part is placed at the circular hole.

[0038] In one embodiment of the present invention, the limiting groove 41 of the clamp lock 4 is an open structure. The limiting groove 41 includes a first groove 411 and a second groove 412. Both the first groove 411 and the second groove 412 are trapezoidal, and the upper bottom of the first groove 411 is the lower bottom of the second groove 412.

[0039] When the clamp is in the closed state, the two rollers 8 are in contact with the edge of the groove 412;

[0040] When the clamp is in the open state, the two rollers 8 are located in the slot 411.

[0041] In one embodiment of the present invention, the rear end of the clamp lock 4 is provided with a floating head mounting groove 42, and a floating head 12 is installed at the floating head mounting groove 42. The floating head 12 is connected to the output end of the cylinder 6. The floating head 12 can be replaced with a corresponding model as needed.

[0042] In one embodiment of the present invention, the gun head base 3 has clamp placement grooves 31 on both sides and a standard part through hole 32 on the front side. The clamp placement grooves 31 restrict the clamp to move in the vertical direction, and the clamp can only rotate in the horizontal direction.

[0043] In one embodiment of the present invention, the clamp 1 is provided with a spring mounting hole 101, which is located at the front end of the pin 2. The pin 2 is vertically arranged and the spring 9 is horizontally arranged.

[0044] In one embodiment of the present invention, the front end of the gun head cylinder seat 5 is provided with a clamp lock placement groove 51, and the rear end of the gun head cylinder seat 5 is provided with a floating head moving groove 52. The floating head moving groove 52 and the clamp lock placement groove 51 are connected. The floating head moves horizontally at the floating head moving groove 52, and the clamp lock moves horizontally at the clamp lock placement groove 51.

[0045] In one embodiment of the present invention, a set screw 13 is further included, which is installed at the middle of the front end of the gun head cylinder seat 5. The set screw 13 serves to limit the position of the floating head 12. It limits the extension position of the cylinder to prevent the clamps from either not clamping tightly or clamping too tightly. Adjusting the position of the set screw 13 allows the extension position of the floating head 12 to be adjustable, ultimately achieving concentricity of the first and second grooves of the two clamps. Compared with the traditional method of tightening the gun head, the adjustment time is greatly shortened.

[0046] The above description is merely an example and illustration of the structure of the present invention. Those skilled in the art can make various modifications or additions to the specific embodiments described, or use similar methods to replace them, as long as they do not deviate from the structure of the present invention or exceed the scope defined in the claims, all of which should fall within the protection scope of the present invention.
