The trigger mechanism 7 penetrates through the shell 1, one end is in contact with the cylinder mechanism 3, the other end is movably connected with the shell 1, and is in an untriggered state. The air inlet mechanism 2 is arranged at the bottom of the shell 1 and is fixedly connected with the shell 1. When the external air source (such as compressed air) enters through the air inlet mechanism 2, the gas flows to the cylinder mechanism 3 through the connecting air pipe 4, and the cylinder mechanism 3 is provided with a driving element inside; when the user needs to knock the workpiece, the trigger mechanism 7 is operated to move the part in contact with the cylinder mechanism 3; the movement of the trigger mechanism 7 causes the air pressure inside the cylinder mechanism 3 to rise, pushing the hammer handle 51 and the rubber hammer 5 connected with the cylinder mechanism 3 to move forward; the rubber hammer 5 is quickly knocked forward against the resistance of the first reset spring 6 under the air pressure. After knocking, the air pressure in the cylinder mechanism 3 decreases, and the first reset spring 6 begins to play a role in pulling the rubber hammer 5 back to the initial position, so as to realize the reciprocating knocking of the workpiece.

[0059] It should be noted that the air inlet mechanism 2 includes a regulating valve 21 and an air inlet 22; wherein the regulating valve 21 is arranged at the bottom of the shell 1, and one end of the regulating valve 21 in the shell 1 is connected with the connecting air pipe 4; the air inlet 22 is arranged at the other end of the regulating valve 21 outside the shell 1, and the air inlet 22 is connected with the other end of the regulating valve 21 outside the shell 1.

[0060] Further, the air inlet 22 is the entrance of the external air source such as compressed air into the hammer, which is connected to the other end of the regulating valve 21 outside the shell 1; the regulating valve 21 is a key control element, which is arranged at the bottom of the shell 1 and connected with the connecting air pipe 4 and the air inlet 22. Through the regulating valve 21, the user can control the air flow and air pressure entering the cylinder mechanism 3; when the external air source enters the connecting air pipe 4 through the air inlet 22 and the regulating valve 21, the gas is delivered to the cylinder mechanism 3; when the trigger mechanism 7 is operated, the air pressure inside the cylinder mechanism 3 rises rapidly, pushing the rubber hammer 5 to move forward for knocking. Through the regulating valve 21, the user can accurately control the air pressure entering the cylinder mechanism 3, so as to realize accurate control of the knocking force.

[0061] It should be noted that the cylinder mechanism 3 includes a cylinder body 31, a piston head 32 and a piston rod 33; wherein the cylinder body 31 is fixedly connected with the inside of the shell 1 through a support, the side of the cylinder body 31 is provided with a ventilation hole 311, a trigger hole 312 and a gas release hole 313; the ventilation hole 311 is connected with the end of the connecting air pipe 4 away from the regulating valve 21; the position of the cylinder body 31 on the side of the trigger hole 312 is in contact with the trigger mechanism 7; the piston head 32 is arranged in the cylinder body 31, the piston head 32 is in contact with the inner wall of the cylinder body 31, and the initial position of the piston head 32 covers the gas release hole 313; one end of the piston rod 33 penetrates through the cylinder body 31 and is connected with the piston head 32, and the other end is connected with the hammer handle 51 away from the hammer head 52.

The side of the cylinder body 31 is provided with a ventilation hole 311, a trigger hole 312 and a gas release hole 313. The ventilation hole 311 is connected with the end of the connecting air pipe 4 away from the regulating valve 21, for receiving the air pressure from the air inlet mechanism 2. The trigger hole 312 is a channel for the interaction between the trigger mechanism 7 and the inside of the cylinder mechanism 3, for controlling the movement of the piston head 32. The gas release hole 313 allows the air pressure inside the cylinder body 31 to be released when the piston head 32 moves; the piston head 32 is arranged in the cylinder body 31 and is in close contact with the inner wall of the cylinder body 31. The initial position of the piston head 32 covers the gas release hole 313 to prevent air pressure leakage. One end of the piston rod 33 penetrates through the cylinder body 31 and is connected with the piston head 32, and the other end is connected with the hammer handle 51 away from the hammer head 52. The piston rod 33 is responsible for converting the linear motion of the piston head 32 into the knocking action of the rubber hammer 5. When the external air source enters the connecting air pipe 4 through the air inlet mechanism 2 and enters the cylinder body 31 through the ventilation hole 311, since the trigger hole 312 is not blocked by the trigger mechanism 7, at this time the inner wall of the cylinder body 31 is not in a sealed state, the gas entering the cylinder body 31 exits from the trigger hole 312; by operating the trigger mechanism 7, the trigger mechanism 7 is moved to block the trigger hole 312, at this time, a sealed space is formed inside the cylinder body 31, with the entry of the external air source, the air pressure in the cylinder body 31 gradually increases, pushing the piston head 32 to move, pushing the piston rod 33 and the rubber hammer 5 to move forward quickly for knocking; due to the movement of the piston head 32, the covered gas release hole 313 is opened, thereby causing the air pressure inside the cylinder body 31 to decrease, and the first return spring 6 starts to work, pulling the piston head 32 and the rubber hammer 5 back to the initial position through the piston rod 33, at this time, the gas release hole 313 is covered by the piston head 32 again, and the air pressure in the cylinder body 31 rises quickly again, pushing the piston head 32 out again, the piston head pushing the piston rod 33 and the rubber hammer 5 to move forward quickly for knocking, and the cycle is repeated to complete the continuous knocking of the workpiece; the user can control the air flow and air pressure entering the cylinder body 31 through the regulating valve 21, thereby realizing accurate control of the knocking force.

[0063] It should be noted that the trigger mechanism 7 includes an L-shaped trigger lever 71 and a second reset spring 72; wherein one end of the L-shaped trigger lever 71 is in contact with the position of the cylinder body 31 on one side of the trigger hole 312, the other end penetrates the shell 1, and the L-shaped trigger lever 71 is movably connected with the shell 1; the second reset spring 72 is sleeved on the end of the L-shaped trigger lever 71 outside the shell 1, one end of the second reset spring 72 is connected with the outer surface of the L-shaped trigger lever 71, and the other end is connected with the shell 1.

[0064] Further, the L-shaped trigger lever 71 is the main part of the trigger mechanism 7, one end of the L-shaped trigger lever 71 penetrates the shell 1 and is movably connected with the shell 1, allowing the L-shaped trigger lever 71 to swing or move under the action of external force; the other end is in contact with the position of the cylinder body 31 on one side of the trigger hole 312, for moving to cover the trigger hole 312 when subjected to external force; one end of the second reset spring 72 is connected with the outer surface of the L-shaped trigger lever 71, and the other end is connected with the shell 1, the second reset spring 72 is sleeved on the end of the L-shaped trigger lever 71 outside the shell 1, for resetting the L-shaped trigger lever 71 to the initial position when the external force acting on the L-shaped trigger lever 71 disappears; when the user needs to perform a knocking action, only need to apply an external force (such as manual pressing) to the end of the L-shaped trigger lever 71 outside the shell 1, the external force causes the L-shaped trigger lever 71 to move, so that the end of the L-shaped trigger lever 71 inside the shell 1 covers the trigger hole 312, forming a closed space inside the cylinder body 31, as the external air source enters, the air pressure in the cylinder body 31 gradually increases, pushing the piston head 32 to move, pushing the piston rod 33 and the rubber hammer 5 to move forward quickly for knocking; due to the movement of the piston head 32, the covered air vent 313 is opened, thereby causing the air pressure inside the cylinder body 31 to decrease, and the first reset spring 6 begins to act, pulling the piston head 32 and the rubber hammer 5 back to the initial position through the piston rod 33, at this time, the air vent 313 is covered by the piston head 32 again, and the air pressure in the cylinder body 31 rises again, pushing the piston head 32 out again, the piston head pushing the piston rod 33 and the rubber hammer 5 to move forward quickly for knocking, and so on, completing the continuous knocking of the workpiece.

[0065] It should be noted that the hammer head 52 and the hammer handle 51 are threadedly connected.

[0066] Further, the threaded connection allows the hammer head 52 and the hammer handle 51 to be disassembled, thereby facilitating the replacement of different types of hammer heads 52.

[0067] It should be noted that the embodiment also includes a handle assembly 8, which is sleeved on the shell 1, and the handle assembly 8 is connected with the shell 1;

[0068] The handle assembly 8 comprises a fixing ring 81 and a handle 82; wherein the fixing ring 81 is sleeved on the outer shell 1, and the inner side wall of the fixing ring 81 is connected with the outer shell 1; the handle 82 is arranged on the outer surface of the fixing ring 81, and the handle 82 is connected with the fixing ring 81.

[0069] Further, as the base part of the handle assembly 8, the fixing ring 81 is closely sleeved on the outer shell 1. Its inner side wall is connected with the outer shell 1 through thread connection, welding or buckle fixing, which ensures the stability of the handle assembly 8. The handle 82 is arranged on the outer surface of the fixing ring 81 and is firmly connected with the fixing ring 81. The handle 82 is designed considering the ergonomic principle, so that the user can hold it comfortably and operate accurately; when using the edge beater, the user can hold the handle 82 comfortably and control the direction and force of the knocking action by adjusting the holding position and force.

[0070] It should be noted that the diameters of the air release hole 313, the trigger hole 312 and the air vent hole 311 are equal.

[0071] Further, when the diameters of the air release hole 313, the trigger hole 312 and the air vent hole 311 are equal, the design and manufacturing process of the cylinder 31 can be simplified.

[0072] It should be noted that the outer surface of the piston head 32 is provided with a sealing ring, and the side of the sealing ring away from the piston head 32 is in contact with the inner wall of the cylinder 1.

[0073] Further, the sealing ring is an annular part made of elastic material (such as rubber, silicone or polyurethane), and its design purpose is to form a tight sealing interface between the piston head 32 and the inner wall of the cylinder 31; the sealing ring is installed on the outer surface of the piston head 32, and the side of the sealing ring away from the piston head 32 is in close contact with the inner wall of the cylinder 31; in this way, the sealing ring effectively prevents gas from leaking out of the gap between the piston head and the cylinder, thereby maintaining the stability of the air pressure inside the cylinder.

[0074] It should be noted that further, the outer surface of the handle 82 is provided with threads.

[0075] Further, by providing threads on the outer surface of the handle 82, sufficient friction is provided to prevent hand slipping.

[0076] According to the edge tacker for vehicle, when in use, a gas source is connected through the air inlet 22, and then is delivered to the cylinder 31 through the connecting air pipe 4 after the adjusting valve 21. The flow and pressure of the gas entering the cylinder 31 can be controlled through the adjusting valve 21. When the trigger mechanism 7 is not triggered, the trigger hole 312 is open, and no closed space is formed in the cylinder 31, and the gas flows out from the trigger hole 312. When the trigger mechanism 7 is triggered (the L-shaped trigger rod 71 moves to block the trigger hole 312), a closed space is formed in the cylinder 31. With the continuous entering of the external gas source, the pressure in the cylinder 31 gradually increases, and the piston head 32 is pushed to move, and the piston rod 33 and the rubber hammer 5 are quickly moved forward to strike. Due to the movement of the piston head 32, the covered air vent 313 is opened, so that the pressure in the cylinder 31 is reduced, and the first reset spring 6 starts to work, and the piston head 32 and the rubber hammer 5 are pulled back to the initial position through the piston rod 33. At this time, the air vent 313 is covered by the piston head 32 again, and the pressure in the cylinder 31 rises again, and the piston head 32 is pushed out again, and the piston head pushes the piston rod 33 and the rubber hammer 5 to quickly move forward to strike. In this way, the workpiece is continuously struck.

[0077] The edge tacker for vehicle has the following beneficial effects:

[0078] (1) The cooperation between the air inlet mechanism, the cylinder mechanism, the connecting air pipe, the rubber hammer, the first reset spring and the trigger mechanism of the edge tacker can realize continuous and automatic striking of the workpiece. Compared with the traditional manual striking, the pneumatic striking method is more labor-saving and the striking force is more uniform.

[0079] (2) The edge tacker realizes the compactness of the structure and the integration of the function through the integration of the shell, the air inlet mechanism, the cylinder mechanism, the connecting air pipe, the rubber hammer, the first reset spring and the trigger mechanism.

[0080] (3) The combination of the air inlet mechanism and the cylinder mechanism enables the tacker to drive the rubber hammer to strike through the gas pressure. By adjusting the gas pressure of the air inlet mechanism, the user can flexibly adjust the striking force to meet the edge requirements of different materials and thicknesses.
